Abstract
Psychosis in children and adolescents has been studied on a spectrum from (common) psychotic experiences to (rare) early-onset schizophrenia spectrum disorders. This research review looks at the state-of-the-art for research across the psychosis spectrum, from evidence on psychotic experiences in community and clinical samples of children and adolescents to findings from psychosis risk syndrome research, to evidence on early-onset psychotic disorders. The review also looks at new opportunities to capture psychosis risk in childhood and adolescence, including opportunities for early intervention, identifies important unanswered questions, and points to future directions for prevention research.

Gouveia M, Morgado T, Costa T, Sampaio F, Rosa A, Sequeira C. Intervention Programmes for First-Episode Psychosis: A Scoping Review. NURSING REPORTS 2025; 15:16. [PMID: 39852638 PMCID: PMC11767625 DOI: 10.3390/nursrep15010016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2024] [Revised: 12/21/2024] [Accepted: 01/07/2025] [Indexed: 01/26/2025] Open
Abstract
The aim of this scoping review was to map intervention programmes for first-episode psychosis by identifying their characteristics, participants, and specific contexts of implementation. It seems reasonable to suggest that early intervention may be beneficial in improving recovery outcomes and reducing the duration of untreated psychosis (DUP). Despite the expansion of these programmes, there are still some significant variations and barriers to access that need to be addressed. In line with the Joanna Briggs Institute (JBI) methodology and the Participants, Concept, and Context (PCC) framework, this review encompasses studies focusing on individuals grappling with early-stage psychosis and their caregivers across a range of settings, including hospital and community environments. The review identified 47 studies from 2002 to 2023, which revealed a great deal of diversity in programme characteristics and implementation contexts. This reflects a global perspective. The results showed that there is a great deal of variety in the characteristics of the programmes, with interventions ranging from single-component strategies, such as cognitive-behavioural therapy (CBT) and cognitive remediation therapy (CRT), to multicomponent programmes that integrate a number of different approaches, including psychosocial, pharmacological, and family-focused strategies. The objectives included attempts to improve cognitive functioning; enhance coping skills; reduce caregiver burden; and address symptoms such as anxiety, depression, and hallucinations. It is notable that there was considerable variation in the frequency, duration, and follow-up periods of the interventions, with some lasting just three sessions over one month and others spanning five years and 48 sessions. The majority of the programmes were delivered in community or outpatient settings, although there were also examples of hospital- and home-based interventions. These findings highlight the value of early interventions and provide a useful resource for adapting programmes to different social and cultural contexts. It would be beneficial for future research to explore how these interventions can be tailored to diverse settings.

Abstract
BACKGROUND To provide precision cognitive remediation therapy (CR) for schizophrenia, we need to understand whether the mechanism for improved functioning is via cognition improvements. This mechanism has not been rigorously tested for potential moderator effects. STUDY DESIGN We used data (n = 377) from a randomized controlled trial using CIRCuiTS, a therapist-supported CR, with participants from first-episode psychosis services. We applied structured equation modeling to test whether: (1) CR hours explain the goal attainment functional outcome (GAS) at posttreatment, (2) global cognitive improvement mediates GAS, and if (3) total symptoms moderate the CR hours to cognitive improvement pathway, and/or negative symptoms moderate the cognition to functioning pathway, testing moderator effects via the mediator or directly on CR hours to functioning path. STUDY RESULTS CR produced significant functioning benefit for each therapy hour (Coeff = 0.203, 95% CI 0.101-0.304, P < .001). The mediated path from CR hours to cognition and cognition to functioning was small and nonsignificant (Coeff = 0.014, 95% CI = -0.010, 0.037, P = .256). Total symptoms did not moderate the path to cognition (P = .211) or the direct path to outcome (P = .896). However, negative symptoms significantly moderated the effect of cognitive improvements on functioning (P = .015) with high negative symptoms reducing the functional gains of improved cognition. CONCLUSIONS Although cognitive improvements were correlated with functioning benefit, they did not fully explain the positive effect of increased therapy hours on functioning, suggesting additional CR factors also contribute to therapy benefit. Negative symptoms interfere with the translation of cognitive improvements into functional gains so need consideration.

Abstract
Background/Objectives: Cognitive impairment is a core feature of schizophrenia, affecting attention, memory, and executive function and contributing significantly to the burden of the disorder. These deficits often begin before the onset of psychotic symptoms and persist throughout life, making their treatment essential for improving outcomes and functionality. This work aims to explore the impact of these impairments at different life stages and the interventions that have been developed to mitigate their effects. Methods: This narrative review examined literature searching for different approaches to treat cognitive impairments in schizophrenia across the lifespan. Results: Cognitive alterations appear before psychosis onset, suggesting a window for primary prevention. Then, a period of relative stability with a slight decline gives the period to secondary and eventually tertiary prevention for more than two decades. Finally, another window for tertiary prevention occurs from the third decade of illness until the later stages of the illness, when a progression in cognitive decline could be accelerated in some cases. Cognitive remediation and physical exercise are evidence-based interventions that should be provided to all patients with disabilities. Conclusions: Treating cognition throughout the whole lifespan is crucial for improving functional outcomes. It is necessary to consider the need for personalized, stage-specific strategies to enhance cognitive function and functioning in patients.

Child Adolesc Psychiatry Ment Health 2024; 18:122. [PMID: 39342296 PMCID: PMC11439254 DOI: 10.1186/s13034-024-00815-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Accepted: 09/19/2024] [Indexed: 10/01/2024] Open
Abstract
BACKGROUND Cognitive impairment presents in both adolescent-onset(ado-OP) and adult-onset psychosis(adu-OP). Age and neurodevelopmental factors likely contribute to cognitive differences. This study aimed to characterize cognitive functions in ado-OP compared to adu-OP in a clinical population with drug-naive first-episode psychosis(FEP). METHODS A total of 788 drug-naive patients with FEP and 774 sex- and age-matched healthy controls(HCs) were included. Participants were divided into four groups by whether they were under or over 21 years of age: adolescent-onset FEP(ado-FEP, n = 380), adult-onset FEP(adu-FEP, n = 408), adolescent HC(ado-HC, n = 334), and adult HC(adu-HC, n = 440). Comprehensive cognitive assessments were performed using the MATRICS Cognitive Consensus Battery(MCCB), covers six cognitive domains: speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning, and problem-solving. Data analyses were conducted using correlation analyses and binary logistic regression. RESULTS The patterns of cognitive domain differences between ado-FEP and adu-FEP were found to be similar to those between ado-HC and adu-HC, whereas cognitive impairments appeared to be more pronounced in patients with adu-OP than ado-OP. The mazes subtest had the maximum effect size(ES) in the FEP(ES = 0.37) and HC(ES = 0.30) groups when comparing the adolescent and adult groups. Cognitive subtests were mostly significantly correlated with negative symptoms, especially for adolescents with FEP, in which all the subtests were significantly correlated with negative symptoms in the ado-FEP group. Better performance in the domains of spatial cognition and problem-solving abilities was more likely in the ado-FEP group than in the adu-FEP group. CONCLUSIONS These findings suggest cognitive differences between adolescents and adults but similar patterns of affected domains in HCs and patients with FEP. Therefore, the development of targeted cognitive interventions tailored to the specific needs of different age groups appears warranted.

Wykes T, Bowie CR, Cella M. Thinking About the Future of Cognitive Remediation Therapy Revisited: What Is Left to Solve Before Patients Have Access? Schizophr Bull 2024; 50:993-1005.

Abstract
In our previous paper on the Future of Cognitive Remediation published more than 10 years ago, we envisaged an imminent and wide implementation of cognitive remediation therapies into mental health services. This optimism was misplaced. Despite evidence of the benefits, costs, and savings of this intervention, access is still sparse. The therapy has made its way into some treatment guidance, but these documents weight the same evidence very differently, causing confusion, and do not consider barriers to implementation. This paper revisits our previous agenda and describes how some challenges were overcome but some remain. The scientific community, with its commitment to Open Science, has produced promising sets of empirical data to explore the mechanisms of treatment action. This same community needs to understand the specific and nonspecific effects of cognitive remediation if we are to provide a formulation-based approach that can be widely implemented. In the last 10 years we have learned that cognitive remediation is not "brain training" but is a holistic therapy that involves an active therapist providing motivation support, and who helps to mitigate the impact of cognitive difficulties through metacognition to develop awareness of cognitive approaches to problems. We conclude that, of course, more research is needed but, in addition and perhaps more importantly at this stage, we need more public and health professionals' understanding of the benefits of this therapy to inform and include this approach as part of treatment regimens.

Abstract
Approximately 8 % of patients with schizophrenia are diagnosed before age 18, and 18 % experience their first symptoms before age 18. This narrative review explores the management of patients with early-onset schizophrenia (EOS) and childhood-onset schizophrenia (COS) from diagnosis to their transition to adult care settings. Early diagnosis of schizophrenia in children and adolescents is essential for improving outcomes, but delays are common due to overlapping of symptoms with developmental phenomena and other psychiatric conditions, including substance use, and lack of clinicians' awareness. Once diagnosed, antipsychotic treatment is key, with specific second-generation agents generally being preferred due to better tolerability and their broader efficacy evidence-base in youth. Dosing should be carefully individualized, considering age-related differences in drug metabolism and side effect liability. Clinicians must be vigilant in detecting early non-response and consider switching or dose escalation when appropriate. Since early age of illness onset is a consistent risk factor for treatment-resistant schizophrenia (TRS), clinicians need to be competent in diagnosing TRS and using clozapine. Since COS and EOS are associated with cognitive deficits and impaired functioning, psychosocial interventions should be considered to improve overall functioning and quality of life. Good long-term outcomes depend on continuous treatment engagement, and successful transitioning from pediatric to adult care requires careful planning, early preparation, and collaboration between pediatric and adult clinicians. Targeting functional outcomes and quality of life in addition to symptom remission can improve overall patient well-being. Comprehensive evaluations, age-specific assessments, and targeted interventions are needed to address the unique challenges of EOS and COS.

Abstract
Deficits in social and occupational function are widely reported in psychosis, yet no one measure of function is currently agreed upon as a gold standard in psychosis research. The aim of this study was to carry out a systematic review and meta-analysis of functioning measures to determine what measures were associated with largest effect sizes when measuring between-group differences, changes over time, or response to treatment. Literature searches were conducted based on PsycINFO and PubMed to identify studies for inclusion. Cross-sectional and longitudinal observational and intervention studies of early psychosis (≤5 years since diagnosis) that included social and occupational functioning as an outcome measure were considered. A series of meta-analyses were conducted to determine effect size differences for between-group differences, changes over time, or response to treatment. Subgroup analyses and meta-regression were carried out to account for variability in study and participant characteristics. One hundred and sixteen studies were included, 46 studies provided data (N = 13 261) relevant to our meta-analysis. Smallest effect sizes for changes in function over time and in response to treatment were observed for global measures, while more specific measures of social and occupational function showed the largest effect sizes. Differences in effect sizes between functioning measures remained significant after variability in study and participant characteristics were accounted for. Findings suggest that more specific measures of social function are better able to detect changes in function over time and in response to treatment.

Abstract
Background Cognitive training (CT) for illness-linked neuropsychological deficits has been attempted in psychiatric disorders and, more recently, in obsessive-compulsive disorder (OCD). However, studies are few and far between, with a limited understanding of factors contributing to efficacy. This article aims to provide a comprehensive critical review of studies employing CT in OCD. Methods This systematic review follows the Preferred Reporting of Items for Systematic Review and Meta-Analyses Protocols. Empirical studies that used any form of CT/remediation in individuals with OCD were included. Results Eight articles met the criteria for inclusion, of which five were randomized controlled trials, two were case series, and one was an open-label trial. The studies have predominantly demonstrated improved trained cognitive functions, with only two showing generalization to untrained domains like clinical symptoms and socio-occupational functioning. Conclusion There are few controlled trials of CT in OCD, which limits conclusions of efficacy. Given the sparse research in the area, the review summarizes the current status of research and examines important methodological considerations that may inform future studies.

Abstract
BACKGROUND Few studies have explored associations between adaptive functioning and cognition in adolescents with early-onset schizophrenia spectrum disorders (EOS). METHODS Adaptive functioning, cognition, positive, negative, and general symptoms were characterized in adolescents with EOS and healthy controls. A modified scale of negative, respectively, general symptoms was used. Bivariate analyses identified correlates of adaptive functioning to be included in multivariate analysis. RESULTS Adolescents with EOS showed significant impairments of social- and neurocognitive functions (-0.86 < Cohen´s ds < -0.58) and adaptive functioning (Cohen´s d = -2.23). Visual memory, verbal working memory, processing speed, reaction time, social cognition, and modified negative and general symptoms correlated significantly with adaptive functioning. The multiple regression analysis revealed only verbal working memory as uniquely associated with adaptive functioning (explaining 22.7 % of its variance). Verbal working memory also associated significantly with adaptive functioning in the context of the nonsignificant modified negative and the significant modified general symptoms dimension. CONCLUSIONS Adolescents with first-episode EOS had large impairments in adaptive functioning and moderate to large cognitive deficits. Verbal working memory was an important associate to concurrent adaptive functioning and may be a treatment target for trials to improve cognitive and adaptive functioning in adolescents with EOS.

Abstract
BACKGROUND Psychosis, even in its early stages, ranks highly among the causes of disability worldwide, resulting in an increased focus on improved recovery of social and occupational functioning. This study aimed to provide an estimate of the effectiveness of psychosocial interventions for improving functioning in early psychosis. We also sought evidence of superiority between intervention approaches. METHODS An electronic search was conducted using PubMed and PsycINFO to identify original articles reporting on trials of psychosocial interventions in early-stage psychosis, published up to December 2020 and is reported following PRISMA guidelines. Data were extracted on validated measures of functioning from included studies and pooled standardised mean difference (SMD) was estimated. RESULTS In total, 31 studies involving 2811 participants were included, focusing on: cognitive behavioural therapy for psychosis (CBTp), family-based therapy, supported employment, cognitive remediation training (CRT) and multi-component psychosocial interventions. Across interventions, improved function was observed (SMD = 0.239; 95% confidence interval 0.115-0.364, p < 0.001). Effect sizes varied by intervention type, stage of illness, length and duration of treatment and outcome measure used. In particular, interventions based on CRT significantly outperformed symptom-focused CBT interventions, while multi-component interventions were associated with largest gains. CONCLUSIONS Psychosocial interventions, particularly when provided as part of a multi-component intervention model and delivered in community-based settings are associated with significant improvements in social and occupational function. This review underscores the value of sensitively tracking and targeting psychosocial function as part of the standard provided by early intervention services.

Analyzing structural and functional brain changes related to an integrative cognitive remediation program for schizophrenia: A randomized controlled trial. Schizophr Res 2023; 255:82-92. [PMID: 36965364 DOI: 10.1016/j.schres.2023.03.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 02/07/2023] [Accepted: 03/11/2023] [Indexed: 03/27/2023]
Abstract
Cognitive remediation has been shown to improve cognition in schizophrenia, but little is known about the specific functional and structural brain changes related to the implementation of an integrative cognitive remediation program. This study analyzed the functional and structural brain changes identified after implementing an integrative cognitive remediation program, REHACOP, in schizophrenia. The program combined cognitive remediation, social cognitive training, and functional and social skills training. The sample included 59 patients that were assigned to either the REHACOP group or an active control group for 20 weeks. In addition to a clinical and neuropsychological assessment, T1-weighted, diffusion-weighted and functional magnetic resonance images were acquired during a resting-state and during a memory paradigm, both at baseline and follow-up. Voxel-based morphometry, tract-based spatial statistics, resting-state functional connectivity, and brain activation analyses during the memory paradigm were performed. Brain changes were assessed with a 2 × 2 repeated-measure analysis of covariance for group x time interaction. Intragroup paired t-tests were also carried out. Repeated-measure analyses revealed improvements in cognition and functional outcome, but no significant brain changes associated with the integrative cognitive remediation program. Intragroup analyses showed greater gray matter volume and cortical thickness in right temporal regions at post-treatment in the REHACOP group. The absence of significant brain-level results associated with cognitive remediation may be partly due to the small sample size, which limited the statistical power of the study. Therefore, further research is needed to clarify whether the temporal lobe may be a key area involved in cognitive improvements following cognitive remediation.

Modeling the interplay of age at onset and sex on cognition in Schizophrenia. Asian J Psychiatr 2022; 75:103202.

Abstract
Cognition remains one of the most critical features of the schizophrenia. A wide range of factors has been associated to neurocognition and, among these, sex and age of onset are two of the most consistently reported to influence the functional and cognitive outcome. This work aims to evaluate the effects of sex and age of onset and their interaction on cognition in 419 subjects with schizophrenia. Analyses of variance and analyses of covariance were performed to evaluate the effect of sex and age at onset on cognition. To model the possible interaction sex-onset on cognition, a separate slope regression analysis was performed. Analyses of variance showed significant differences between sexes for age and age at onset, both significantly higher among females, as well as for Executive Functions, with higher performance among males. When compared according to age at onset, late-onset patients performed better than both early- and intermediate-onset ones in Verbal Memory subtest, with a significant effect of length of illness. Moreover, early-onset patients showed a significantly lower IQ compared to both intermediate and late-onset ones, with no significant effect of length of illness. Finally, the separate slope regression revealed a significant interaction between sex and age at onset, with early-onset being associated to a worse global cognition only among male patients. Our finding of a significant sex-onset interaction effect on neurocognition sheds new light on the complex issue of cognitive heterogeneity in schizophrenia. Our data may help towards the development of personalized programs for preventive and rehabilitative purposes.

Abstract
BACKGROUND Cognitive deficits at the first episode of schizophrenia are predictive of functional outcome. Interventions that improve cognitive functioning early in schizophrenia are critical if we hope to prevent or limit long-term disability in this disorder. METHODS We completed a 12-month randomized controlled trial of cognitive remediation and of long-acting injectable (LAI) risperidone with 60 patients with a recent first episode of schizophrenia. Cognitive remediation involved programs focused on basic cognitive processes as well as more complex, life-like situations. Healthy behavior training of equal treatment time was the comparison group for cognitive remediation, while oral risperidone was the comparator for LAI risperidone in a 2 × 2 design. All patients were provided supported employment/education to encourage return to work or school. RESULTS Both antipsychotic medication adherence and cognitive remediation contributed to cognitive improvement. Cognitive remediation was superior to healthy behavior training in the LAI medication condition but not the oral medication condition. Cognitive remediation was also superior when medication adherence and protocol completion were covaried. Both LAI antipsychotic medication and cognitive remediation led to significantly greater improvement in work/school functioning. Effect sizes were larger than in most prior studies of first-episode patients. In addition, cognitive improvement was significantly correlated with work/school functional improvement. CONCLUSIONS These results indicate that consistent antipsychotic medication adherence and cognitive remediation can significantly improve core cognitive deficits in the initial period of schizophrenia. When combined with supported employment/education, cognitive remediation and LAI antipsychotic medication show separate significant impact on improving work/school functioning.

Abstract
BACKGROUND Psychotic disorders are commonly accompanied by intense psychological burden, and psychological interventions are usually needed in order to reduce the symptoms and help in maintaining or improving the level of psychological and social functioning after the onset of psychosis. The evidence-base for treating young people at risk for psychosis and adults with psychotic disorders is accumulating. Yet, pervasive systematic literature reviews that would include patients from the full age range being the most essential period for the risk of developing a psychotic disorder, a wide range of psychological interventions, and various types of clinical trials, have been lacking. The aim of this systematic review is to fill the gap by presenting the current research evidence from clinical trials on the effectiveness of psychological interventions for treating young people (12-30) with psychotic disorders. METHODS A systematic search was conducted in PubMed and PsycINFO followed by a 3-step screening process based on the PICOS strategy. Risk of bias of the included studies was assessed by the Mixed Methods Appraisal Tool (MMAT). Extracted data from the included studies is reported using a narrative synthesis. RESULTS Of the 1,449 publications screened, 40 from 25 studies were included in the review. Of these, 10 studies reported results from cognitive or behavioral therapy, nine from cognitive remediation therapy (CRT), and six from other types of therapies (i.e., integrative interventions combining psychoeducation and family/group interventions). All but one study found the target interventions to be effective, but the results mostly did not differ significantly from the control conditions in reducing symptoms and improving functioning, preventing relapses and hospitalization, or improving psychological or family variables. The most consistent findings were from CRT, showing more improvement in cognitive functioning compared to control conditions while not being superior in reducing symptom severity. Integrative interventions might be effective in treating young people suffering from psychotic disorders. CONCLUSION There is some evidence that psychological interventions are effective for young people with psychotic disorders. However, with regard to symptom severity, psychotherapy does not outperform control conditions, and the results do not strongly favor any specific type of treatment.

Abstract
BACKGROUND Cognitive remediation therapy (CRT) and Computerized CRT (CCRT) improve cognition and functioning, but there is no direct evidence of whether there is an advantage of using a computer. This study fills this gap and extends research evidence to the long-term effect of these two treatments in a large sample of Chinese inpatients with a diagnosis of schizophrenia. METHOD We conducted a randomized single-blind, follow-up study with participants randomized to receive CCRT (n = 144), CRT (n = 72) or Active control (n = 54) for 12 weeks with 4-5 sessions per week. The main outcome was cognition (MATRICS Consensus Cognitive Battery total score, MCCB), and secondary outcomes were cognitive domains, symptoms and functioning assessed at baseline (0 month), post-treatment (3 months) and follow-up (6, 12 and 18 months). RESULTS The primary outcome (MCCB total score) improved in both treatment groups which was maintained at 18 months but did not differ between treatment groups. Post hoc analysis demonstrated that the CRT group had an advantage over CCRT for the Trail Making and Symbol Coding Tests (all p < 0.05), which lasted for almost 18 months. CONCLUSIONS Both CCRT and CRT contribute to general cognitive improvements in schizophrenia and the overall efficacy was similar. The effects were maintained for 18th months. Exploratory analyses revealed few differences except that CRT had a processing speed advantage.

Abstract
Background Impairment in a wide range of cognitive abilities has been consistently reported in individuals with schizophrenia. Both neurocognitive and social cognitive deficits are thought to underlie severe functional disabilities associated with schizophrenia. Despite the key role in schizophrenia outcome, cognition is still poorly assessed in both research and clinical settings. Methods In this guidance paper, we provide a systematic review of the scientific literature and elaborate several recommendations for the assessment of cognitive functions in schizophrenia both in research settings and in real-world clinical practice. Results Expert consensus and systematic reviews provided guidance for the optimal assessment of cognitive functions in schizophrenia. Based on the reviewed evidence, we recommend a comprehensive and systematic assessment of neurocognitive and social cognitive domains in schizophrenia, in all phases of the disorder, as well as in subjects at risk to develop psychosis. This European Psychiatric Association guidance recommends not only the use of observer reports but also self-reports and interview-based cognitive assessment tools. The guidance also provides a systematic review of the state of the art of assessment in the first episode of psychosis patients and in individuals at risk for psychosis. Conclusion The comprehensive review of the evidence and the recommendations might contribute to advance the field, allowing a better cognitive assessment, and avoiding overlaps with other psychopathological dimensions. The dissemination of this guidance paper may promote the development of shared guidelines concerning the assessment of cognitive functions in schizophrenia, with the purpose to improve the quality of care and to obtain recovery.

Abstract
This study analyzed the effectiveness of an integrative cognitive remediation program (REHACOP) in improving neurocognition, social cognition, creativity, functional outcome, and clinical symptoms in patients with schizophrenia. In addition, possible mediators predicting improvement in functional outcomes were explored. The program combined cognitive remediation with social cognitive training and social and functional skill training over 20 weeks. The sample included 94 patients, 47 in the REHACOP group and 47 in the active control group (occupational activities). Significant differences were found between the two groups in change scores of processing speed, working memory, verbal memory (VM), inhibition, theory of mind, emotion processing (EP), figural creative strengths, functional competence, disorganization, excitement, and primary negative symptoms. A mediational analysis revealed that changes in VM, inhibition, and EP partially explained the effect of cognitive remediation on functional competence improvement. This study provides initial evidence of the effect of integrative cognitive remediation on primary negative symptoms and creativity.

Abstract
OBJECTIVE After young adults experience a first episode of psychosis, many express a need for help with education and employment. A quality improvement collaborative (QIC) launched in the Netherlands aimed to reinforce vocational recovery by improving participation in education and employment and by enhancing cognitive skills and self-management. This study examined methods used to implement interventions, barriers and facilitators, and implementation outcomes (fidelity, uptake, and availability). METHODS The Breakthrough Series was the model for change. Three evidence-based interventions were implemented to achieve targeted goals: individual placement and support (IPS), cognitive remediation, and shared decision making. Fidelity scores were obtained with fidelity scales. RESULTS Eighty-five professionals and 332 patients representing 14 teams treating patients with early psychosis were included in the 24-month QIC. Of this group, 252 patients participated in IPS, 52 in cognitive remediation, and 39 in shared decision making. By month 22, teams attained moderate-to-high mean fidelity scores, with an average of 3.2 on a 4-point scale for cognitive remediation, 3.7 on a 5-point scale for IPS, and 4.9 on a 6-point scale for shared decision making. CONCLUSIONS Over 24 months, use of a Breakthrough QIC to implement three interventions aimed at improving vocational recovery in teams delivering services for early psychosis yielded mixed results in terms of uptake and availability and moderate-to-high results in terms of fidelity. When implementing these types of interventions in this population, a multifaceted implementation model and a focused testing phase for computerized interventions appear needed, preferably with a maximum of two interventions implemented simultaneously.

Abstract
OBJECTIVE Cognitive impairment in schizophrenia predicts functional outcomes and is largely unresponsive to pharmacology or psychotherapy; it is thus a critical unmet treatment need. This article presents the impact of remotely completed, intensive, targeted auditory training (AT) vs control condition computer games (CG) in a double-blind randomized trial in young adults with recent-onset schizophrenia. METHOD Participants (N = 147) were assessed for cognition, symptoms, and functioning at baseline, post-intervention, and at 6-month follow-up. All participants were provided with laptop computers and were instructed to complete 40 hours remotely of training or computer games. An intent-to-treat analysis (N = 145) was performed using linear mixed models with time modeled as a continuous variable. Planned contrasts tested the change from baseline to post-training, baseline to 6-month follow-up, and post-training to 6-month follow-up. RESULTS Global Cognition, which had improved in the AT group relative to the CG group at post-training, showed durable gains at 6-month follow-up in an omnibus group-by-time interaction test (F(1,179) = 4.80, P = .030), as did Problem-Solving (F(1,179) = 5.13, P = .025), and Speed of Processing improved at trend level significance (F(1,170) = 3.80, P = .053). Furthermore, the AT group showed significantly greater improvement than the CG group in positive symptoms (F(1,179) = 4.06, P = .045). CONCLUSIONS These results provide the first evidence of durable cognitive gains and symptom improvement at follow-up of cognitive training (CT) in early schizophrenia completed independently and remotely. While functioning did not show significant improvement, these findings suggest that intensive targeted CT of auditory processing is a promising component of early intervention to promote recovery from psychosis.

Abstract
BACKGROUND The 'jumping to conclusions' (JTC) bias is associated with both psychosis and general cognition but their relationship is unclear. In this study, we set out to clarify the relationship between the JTC bias, IQ, psychosis and polygenic liability to schizophrenia and IQ. METHODS A total of 817 first episode psychosis patients and 1294 population-based controls completed assessments of general intelligence (IQ), and JTC, and provided blood or saliva samples from which we extracted DNA and computed polygenic risk scores for IQ and schizophrenia. RESULTS The estimated proportion of the total effect of case/control differences on JTC mediated by IQ was 79%. Schizophrenia polygenic risk score was non-significantly associated with a higher number of beads drawn (B = 0.47, 95% CI -0.21 to 1.16, p = 0.17); whereas IQ PRS (B = 0.51, 95% CI 0.25-0.76, p < 0.001) significantly predicted the number of beads drawn, and was thus associated with reduced JTC bias. The JTC was more strongly associated with the higher level of psychotic-like experiences (PLEs) in controls, including after controlling for IQ (B = -1.7, 95% CI -2.8 to -0.5, p = 0.006), but did not relate to delusions in patients. CONCLUSIONS Our findings suggest that the JTC reasoning bias in psychosis might not be a specific cognitive deficit but rather a manifestation or consequence, of general cognitive impairment. Whereas, in the general population, the JTC bias is related to PLEs, independent of IQ. The work has the potential to inform interventions targeting cognitive biases in early psychosis.

Abstract
Negative symptoms of schizophrenia have generally been defined using five factors; however, few studies have examined the relationship between these five factors and functional outcomes. In addition, there is no definitive conclusion regarding the association between negative symptoms and various aspects of functional outcomes (daily living, social, and vocational). This study is aimed at examining the relationship between these five domains of negative symptoms and different functional outcomes. Patients diagnosed with chronic schizophrenia (n = 100) were selected for the evaluation. We used the Brief Negative Symptom Scale to assess negative symptoms, the Brief Psychiatric Rating Scale to assess positive symptoms, the Schizophrenia Cognition Rating Scale to assess cognition, and the Evaluative Beliefs Scale (negative self-assessment) to assess psychological factors. We analyzed their relative impact on Social Functioning Scale domains using hierarchical multiple regression analysis. Concerning the relationship between daily living and negative symptoms, cognitive function showed the highest association with residential outcomes, such as self-care and shopping, while avolition appeared to show an additional contribution; however, for recreational outcomes, avolition showed the main association, whereas cognitive function showed no additional contribution. For social outcomes, asociality and negative self-assessment showed the main associations, while vocational outcomes were determined by both cognitive function and multiple negative symptoms, such as avolition, anhedonia, asociality, and alogia. Since negative symptom domains appear to differentially impact each outcome, specifically daily living outcome, it is important to evaluate the residential outcomes and recreational outcomes separately. Overall, the present study points to the importance of formulating psychosocial treatment strategies specific for each type of preferred outcome in patients with schizophrenia.

Abstract
BACKGROUND While Cognitive Remediation (CR) is effective in reducing cognitive and functioning difficulties in people with schizophrenia, there is variability in treatment response. Previous research suggested that participants' age may be a significant moderator of CR response. AIM To examine the impact of participants' age on CR outcomes. METHOD Individual participant data were accessed from fourteen CR randomised controlled trials. We tested the moderating effect of participants' age on cognitive and functioning outcomes using multivariate linear models. RESULTS Data from 1084 people with a diagnosis of schizophrenia were considered. Participants had a mean age of 36.6 years (SD 11), with 11.6 years of education (SD 2.8), and an average duration of illness of 13.5 years (SD 10.7). Multivariate models showed that participants' age, when considered as a continuous variable, was not a significant moderator of treatment effect for cognitive and functioning outcomes. However, when participants were split by median age, younger participants showed higher gains in executive functions following CR compared to older participants (p=0.02). CONCLUSION These results suggest that participants' age does not moderate most CR outcomes. However, larger age differences may influence the effect of CR on executive function. This may suggest some adaptation of CR practice according to participants' age. These findings inform the CR personalisation agenda.

Abstract
BACKGROUND IQ and IQ decline are considered risk factors for poor prognosis in people with a diagnosis of schizophrenia. However, it is still not clear if, at least in part, IQ and IQ decline influence long-term outcomes via a negative effect on interventions. AIM To identify whether current IQ, estimated premorbid IQ, or IQ decline moderate the response to cognitive remediation (CR). METHOD Individual participant data from twelve randomised controlled trials of CR were considered. Hierarchical and k-means analyses were carried out to identify different IQ clusters. The moderating effect of estimated premorbid IQ, current IQ, and different IQ clusters (preserved, deteriorated and compromised trajectories) on cognitive outcomes at post-therapy and follow-up were evaluated using multiple linear regression. RESULTS Data from 984 participants (CR = 544, control = 440) with schizophrenia and schizoaffective disorders were considered. The sample had a mean current IQ of 84.16 (SD 15.61) and estimated premorbid IQ of 95.82 (SD 10.63). Current IQ moderated working memory outcomes: people with higher IQ had larger working memory gains after therapy compared to those with a lower IQ. Those with a preserved IQ had better cognitive outcomes compared to either the deteriorated or compromised IQ groups, and those with a deteriorated IQ had better outcomes compared to those in the compromised IQ group. CONCLUSION Current IQ is a significant moderator of cognitive gains after CR. These findings highlight the need to evaluate whether therapy adaptations (e.g. offering more sessions) can attenuate this effect so that those with lower IQ may derive benefit similar to those with higher IQ.

Abstract
BACKGROUND Psychosis is an illness characterised by alterations in thoughts and perceptions resulting in delusions and hallucinations. Psychosis is rare in adolescents but can have serious consequences. Antipsychotic medications are the mainstay treatment, and have been shown to be effective. However, there is emerging evidence on psychological interventions such as cognitive remediation therapy, psycho-education, family therapy and group psychotherapy that may be useful for adolescents with psychosis. OBJECTIVES To assess the effects of various psychological interventions for adolescents with psychosis. SEARCH METHODS We searched the Cochrane Schizophrenia Group's study-based Register of Trials including clinical trials registries (latest, 8 March 2019). SELECTION CRITERIA All randomised controlled trials comparing various psychological interventions with treatment-as-usual or other psychological treatments for adolescents with psychosis. For analyses, we included trials meeting our inclusion criteria and reporting useable data. DATA COLLECTION AND ANALYSIS We independently and reliably screened studies and we assessed risk of bias of the included studies. For dichotomous data, we calculated risk ratios (RRs) and 95% confidence intervals (CIs) on an intention-to-treat basis. For continuous data, we used mean differences (MDs) and the 95% CIs. We used a random-effects model for analyses. We created a 'Summary of findings' table using GRADE. MAIN RESULTS The current review includes 7 studies (n = 319) assessing a heterogenous group of psychological interventions with variable risk of bias. Adverse events were not reported by any of the studies. None of the studies was sponsored by industry. Below, we summarise the main results from four of six comparisons, and the certainty of these results (based on GRADE). All scale scores are average endpoint scores. Cognitive Remediation Therapy (CRT) + Treatment-as-Usual (TAU) versus TAU Two studies compared adding CRT to participants' TAU with TAU alone. Global state (CGAS, high = good) was reported by one study. There was no clear difference between treatment groups (MD -4.90, 95% CI -11.05 to 1.25; participants = 50; studies = 1, very low-certainty). Mental state (PANSS, high = poor) was reported by one study. Scores were clearly lower in the TAU group (MD 8.30, 95% CI 0.46 to 16.14; participants = 50; studies = 1; very low-certainty). Clearly more participants in the CRT group showed improvement in cognitive functioning (Memory digit span test) compared to numbers showing improvement in the TAU group (1 study, n = 31, RR 0.58, 95% CI 0.37 to 0.89; very low-certainty). For global functioning (VABS, high = good), our analysis of reported scores showed no clear difference between treatment groups (MD 5.90, 95% CI -3.03 to 14.83; participants = 50; studies = 1; very low-certainty). The number of participants leaving the study early from each group was similar (RR 0.93, 95% CI 0.32 to 2.71; participants = 91; studies = 2; low-certainty). Group Psychosocial Therapy (GPT) + TAU versus TAU One study assessed the effects of adding GPT to participants' usual medication. Global state scores (CGAS, high = good) were clearly higher in the GPT group (MD 5.10, 95% CI 1.35 to 8.85; participants = 56; studies = 1; very low-certainty) but there was little or no clear difference between groups for mental state scores (PANSS, high = poor, MD -4.10, 95% CI -8.28 to 0.08; participants = 56; studies = 1, very low-certainty) and no clear difference between groups for numbers of participants leaving the study early (RR 0.43, 95% CI 0.15 to 1.28; participants = 56; studies = 1; very low-certainty). Cognitive Remediation Programme (CRP) + Psychoeducational Treatment Programme (PTP) versus PTP One study assessed the effects of combining two types psychological interventions (CRP + PTP) with PTP alone. Global state scores (GAS, high = good) were not clearly different (MD 1.60, 95% CI -6.48 to 9.68; participants = 25; studies = 1; very low-certainty), as were mental state scores (BPRS total, high = poor, MD -5.40, 95% CI -16.42 to 5.62; participants = 24; studies = 1; very low-certainty), and cognitive functioning scores (SPAN-12, high = good, MD 2.40, 95% CI -2.67 to 7.47; participants = 25; studies = 1; very low-certainty). Psychoeducational (PE) + Multifamily Treatment (MFT) Versus Nonstructured Group Therapy (NSGT, all long-term) One study compared (PE + MFT) with NSGT. Analysis of reported global state scores (CGAS, high = good, MD 3.38, 95% CI -4.87 to 11.63; participants = 49; studies = 1; very low-certainty) and mental state scores (PANSS total, high = poor, MD -8.23, 95% CI -17.51 to 1.05; participants = 49; studies = 1; very low-certainty) showed no clear differences. The number of participants needing hospital admission (RR 0.84, 95% CI 0.36 to 1.96; participants = 49; studies = 1) and the number of participants leaving the study early from each group were also similar (RR 0.52, 95% CI 0.10 to 2.60; participants = 55; studies = 1; low-certainty). AUTHORS' CONCLUSIONS Most of our estimates of effect for our main outcomes are equivocal. An effect is suggested for only four outcomes in the SOF tables presented. Compared to TAU, CRT may have a positive effect on cognitive functioning, however the same study reports data suggesting TAU may have positive effect on mental state. Another study comparing GPT with TAU reports data suggesting GPT may have a positive effect on global state. However, the estimate of effects for all the main outcomes in our review should be viewed with considerable caution as they are based on data from a small number of studies with variable risk of bias. Further data could change these results and larger and better quality studies are needed before any firm conclusions regarding the effects of psychological interventions for adolescents with psychosis can be made.

Abstract
BACKGROUND Computerized cognitive remediation therapy (CCRT) is generally effective for the cognitive deficits of schizophrenia. However, there is much uncertainty about what factors mediate or moderate effectiveness and are therefore important to personalize treatment and boost its effects. METHOD In total, 311 Chinese inpatients with Diagnostic and Statistical Manual of Mental Disorders-IV schizophrenia were randomized to receive CCRT or Active control for 12 weeks with four to five sessions per week. All participants were assessed at baseline, post-treatment and 3-month follow-up. The outcomes were cognition, clinical symptoms and functional outcomes. RESULTS There was a significant benefit in the MATRICS Consensus Cognitive Battery (MCCB) total score for CCRT (F1,258 = 5.62; p = 0.02; effect size was 0.27, 95% confidence interval 0.04-0.49). There were no specific moderators of CCRT improvements. However, across both groups, Wisconsin Card Sort Test improvement mediated a positive effect on functional capacity and Digit Span benefit mediated decreases in positive symptoms. In exploratory analyses younger and older participants showed cognitive improvements but on different tests (younger on Symbol Coding Test, while older on the Spatial Span Test). Only the older age group showed MSCEIT benefits at post-treatment. In addition, cognition at baseline negatively correlated with cognitive improvement and those whose MCCB baseline total score was around 31 seem to derive the most benefit. CONCLUSIONS CCRT can improve the cognitive function of patients with schizophrenia. Changes in cognitive outcomes also contributed to improvements in functional outcomes either directly or solely in the context of CCRT. Age and the basic cognitive level of the participants seem to affect the cognitive benefits from CCRT.

Improving social functioning in community-dwelling patients with schizophrenia: a randomized controlled computer cognitive remediation therapy trial with six months follow-up. Psychiatry Res 2020; 287:112913. [PMID: 32203751 DOI: 10.1016/j.psychres.2020.112913] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 03/08/2020] [Accepted: 03/08/2020] [Indexed: 11/20/2022]
Abstract
Computerized cognitive remediation therapy (CCRT) has been found to generally improve cognition among patients with schizophrenia, but its effect on functioning has not been extensively studied. This study addressed this gap in the literature by investigating the effect of CCRT and its long-term efficacy among community-dwelling patients with schizophrenia. 157 Chinese patients with schizophrenia were recruited from communities and randomized to CCRT (n = 78) or treatment as usual (TAU; n = 79) groups for 12 weeks with 4-5 sessions per week. Neurocognition, functioning, and symptoms of participants were assessed at baseline, after treatment, and at the 6 month follow-up. The CCRT group showed significantly greater improvements than the TAU group regarding the MATRICS Consensus Cognitive Battery (MCCB) total score and social cognition score. Significant cognitive benefits for functioning were observed (Personal and Social Performance scale, PSP). Moreover, improvement of the MCCB total score mediated a positive effect on functional capacity (UCSD Performance-based Skills Assessment, UPSA), and mediated decreases in negative symptoms across both groups. CCRT improved social functioning and general cognitive functioning among community-dwelling patients with schizophrenia. These improvements persisted for 6 months after treatment. CCRT also led to improvements in functioning and symptom severity by modulating cognitive functioning.

Role of Executive Function in Response to a Problem Solving Based Psychoeducational Intervention in Adolescents with Psychosis: The PIENSA Trial Revisited. J Clin Med 2019; 8:jcm8122108.

Abstract
An improvement in negative symptoms and a reduction in the number of visits to the emergency department have been reported in a problem solving based psychoeducational group intervention (PE) for adolescents with psychosis relative to a nonstructured group (NS). One of the factors that may play a role on the response to PE treatment is executive function (EF), a crucial cognitive domain for problem-solving performance. We aimed to examine the role of EF in response to PE treatment versus an NS group. We examined the associations between changes in cognition and in clinical/functional variables within each treatment group using Spearman-ranked and partial correlation analyses. A total of 22 individuals (mean age: 16.3) were randomized to PE (N = 10) and NS (N = 12). We found an association between improvements in EF performance and a reduction in positive symptoms (rs = –0.756, p = 0.030 for semantic fluency), reduction in negative symptoms (r = 0.758, p = 0.029 for semantic; rs = –0,733, p = 0.025 for verbal fluency), and reduction in the number of visits to the emergency department (r = –0,743, p = 0.035 for semantic fluency) in the PE group. No associations were found in the NS group. Our results suggest that EF may play a role in the specific improvements observed in the PE group. This may have implications in the development of new areas of clinical intervention focusing on the role of cognitive functioning in response to psychosocial treatments in psychosis.

Abstract
We explored the adherence to a home-delivered, computer-based, cognitive remediation protocol in a first-episode psychosis outpatient cohort. Seventeen patients underwent a cognitive training protocol for 6 months using an online platform accessible from their home under the supervision of a qualified neuropsychologist. Neuropsychological, psychopathological, and functional data were collected at baseline and postintervention, whereas qualitative appraisal of the intervention was assessed monthly. Overall, participants' evaluation of the program was positive. This was reflected in a good adherence rate with 12 (70%) of 17 patients completing 80% of the prescribed sessions. Exploratory analysis revealed significant improvements in sustained attention (p = 0.020) and verbal memory (p = 0.018). A decrease in negative symptoms and an improvement on the Clinical Global Impression were also found (p = 0.009). We believe these are encouraging results to further explore the adopted delivery approach, which could facilitate access to cognitive training earlier and to a larger group of patients.

Abstract
BACKGROUND: Neurocognitive and social cognitive impairments are core characteristics of psychotic disorders, which are present in the first episode of psychosis (FEP) and strongly predict poor social functioning. Addressing cognitive impairments through cognitive training and remediation (CTR) may be a crucial component of recovery-oriented treatment. AIMS: The objectives of this review were to (1) evaluate the CTR theoretical basis and intervention components and (2) examine the effects of CTR on cognition and social functioning in FEP. METHOD: A combined search of Ovid Medline, Embase, and Psych Info databases was conducted using keywords. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Quality and risk of bias were assessed using established instruments. RESULTS: Ten randomized controlled trials were included in this review and had an overall fair to poor quality. CTR interventions in FEP utilize a range of theoretical backgrounds, with most including a focus on higher order cognitive processes. Varied doses and intervention components are used. All but one study found improvements in at least one cognitive domain. Global cognition, verbal learning, and memory and executive function were most commonly improved. Three studies found an effect on a range of functional outcomes. CONCLUSIONS: A broad range of CTR interventions have promising effects for addressing cognitive impairments in FEP. Evidence of functional impact is less consistent. Further research is needed in FEP on CTR targeting sensory and perceptual processes, and to identify CTR intervention targets and treatment components that will lead to robust improvements in cognition and functioning.

Abstract
OBJECTIVE Cognitive remediation therapy is a moderately effective intervention for ameliorating cognitive deficits in individuals with schizophrenia-related disorders. With reports of considerable variability in individual response to cognitive remediation therapy, we need to better understand factors that influence cognitive remediation therapy efficacy to realise its potential. A systematic review was conducted to identify and evaluate predictors of cognitive outcome. METHODS An electronic database search was conducted identifying peer-reviewed articles examining predictors of cognitive response to cognitive remediation therapy. RESULTS A total of 40 articles accounting for 1681 cognitive remediation therapy participants were included; 81 distinct predictors of cognitive response were identified. Data synthesis and discussion focused on 20 predictors examined a minimum three times in different studies. Few of the examined predictors of cognitive outcome following cognitive remediation therapy were significant when examined through systematic review. A strong trend was found for baseline cognition, with reasoning and problem solving and working memory being strongly predictive of within-domain improvement. Training task progress was the most notable cross-domain predictor of cognitive outcome. CONCLUSION It remains unclear why a large proportion of participants fail to realise cognitive benefit from cognitive remediation therapy. However, when considering only those variables where a majority of articles reported a statistically significant association with cognitive response to cognitive remediation therapy, three stand out: premorbid IQ, baseline cognition and training task progress. Each of these relates in some way to an individual's capacity or potential for change. There is a need to consolidate investigation of potential predictors of response to cognitive remediation therapy, strengthening the evidence base through replication and collaboration.

Abstract
BACKGROUND Early onset psychosis (EOP), referring to psychosis with onset before the age of 18 years, is a more severe form of psychosis associated with worse prognosis. While medication is the treatment of choice, psychological interventions are also considered to have an important role in the management of symptoms and disability associated with this condition. The present review aimed to explore the effectiveness of such interventions. METHOD An electronic search was conducted on the Embase, Medline, and PsychInfo databases for papers of randomized controlled trials (RCTs) referring to psychological interventions in EOP. References of identified papers were hand searched for additional studies. Identified studies were quality assessed. RESULTS Eight studies were included in the present review evaluating cognitive remediation therapy (CRT), cognitive behavioural therapy (CBT), a family intervention and psychoeducation. CRT was associated with improvement in cognitive function and CBT and CRT seem to also have a positive effect in psychosocial functioning. Symptom reduction appears to not be significantly affected by the proposed treatments. CONCLUSIONS There is some evidence supporting the effectiveness of psychological interventions in EOP. However, most research on adolescents is focused on CRT and its effects on cognitive deficits. More studies on the effects of psychological interventions in EOP are needed.

Abstract
Computerised cognitive remediation therapy (CCRT) has been shown to improve cognitive function in individuals with schizophrenia beyond effects of other forms of therapy. However, results vary between studies, and most are aimed at individuals who are living in the community. Very few studies have investigated its efficacy in psychiatric wards in order to assess whether or not this is a suitable site to start the therapy. This study evaluated CCRT efficacy among schizophrenia inpatients who received a broad range of therapeutic interventions in a psychiatric ward. A randomised controlled trial of CCRT versus an active control in 66 young inpatients with a diagnosis of schizophrenia was conducted. The intervention lasted for 6 weeks and its efficacy was assessed with the composite score of the MATRICS Consensus Cognitive Battery. Both groups improved similarly in cognitive function and psychopathological symptoms. However, the CCRT group improved more than the controls in negative symptoms. This result shows that providing a drill and practice cognitive remediation to inpatients does not produce benefits for cognitive functioning substantially greater than other forms of therapy provided in a ward, but it is more efficient in reduction of negative symptoms. Our results suggest that CRT might be considered as a promising intervention for reducing negative symptoms in schizophrenia individuals.

Abstract
OBJECTIVE The REHABase project is a French observational, prospective, and multicenter cohort study of serious mental illness and autism spectrum disorder (ASD), launched in 2016 for a planned minimum duration of 15 years. The aim is to characterize the care and quality-of-life needs of participants. This article presents initial results from data collection. METHODS Psychosocial, cognitive, and functional data were collected at baseline, annually, and after rehabilitation care. Data from the baseline evaluation on diagnoses, medications, well-being, insight, life satisfaction, and care needs are presented. The clinical profiles of REHABase participants with serious mental illness or ASD were assessed in relation to their level of satisfaction with life and well-being in nine life dimensions and their needs, according to their stage of recovery in a five-stage model. RESULTS Baseline data were collected for 1,397 participants between January 2016 and August 2018. Main diagnoses were schizophrenia spectrum disorder (49%); ASD (13%); and personality (12%), bipolar (9%), and major depressive (6%) disorders. More than 50% of participants reported needs for care or interventions in four of nine dimensions: employment, cognitive functioning, symptom management, and interpersonal relationships. Nearly half of participants were not in the active stages of recovery (stages 4 and 5), and even those considered to have reached the final stage continued to require help in several areas. CONCLUSIONS Most participants had already received psychiatric care for several years, and most remained dissatisfied with their social and emotional life and their psychological well-being.

Abstract
Schizophrenia is a debilitating psychiatric disorder and patients experience significant comorbidity, especially cognitive and psychosocial deficits, already at the onset of disease. Previous research suggests that treatment during the earlier stages of disease reduces disease burden, and that a longer time of untreated psychosis has a negative impact on treatment outcomes. A targeted literature review was conducted to gain insight into the definitions currently used to describe patients with a recent diagnosis of schizophrenia in the early course of disease ('early' schizophrenia). A total of 483 relevant English-language publications of clinical guidelines and studies were identified for inclusion after searches of MEDLINE, MEDLINE In-Process, relevant clinical trial databases and Google for records published between January 2005 and October 2015. The extracted data revealed a wide variety of terminology and definitions used to describe patients with 'early' or 'recent-onset' schizophrenia, with no apparent consensus. The most commonly used criteria to define patients with early schizophrenia included experience of their first episode of schizophrenia or disease duration of less than 1, 2 or 5 years. These varied definitions likely result in substantial disparities of patient populations between studies and variable population heterogeneity. Better agreement on the definition of early schizophrenia could aid interpretation and comparison of studies in this patient population and consensus on definitions should allow for better identification and management of schizophrenia patients in the early course of their disease.

Abstract
AIM Schizophrenia and 22q11.2 deletion syndrome (22q11DS) share similar patterns of cognitive deficits. Up to 30% of those with 22q11DS develop schizophrenia during early adulthood. As cognitive decline has recently been found to predict onset of psychosis in adolescents with 22q11DS, early interventions such as cognitive remediation (CR) during adolescence are warranted. This paper investigates the durability of a remote, computerized, CR programme for youth with 22q11DS. Our aim was to determine if the positive effects of CR persisted 6 months beyond intervention completion. METHODS A longitudinal design with 21 participants serving as their own controls was used. Youth were seen for neurocognitive assessments at pre-treatment, after the targeted 8-month intervention, at post-treatment, and 6 months after for follow-up. During the intervention, cognitive coaches met remotely with participants for CR via video conferencing three times a week, and offered task-specific strategies. To determine if intervention improvements held across the 6-month follow-up period, neurocognitive measures were statistically examined with repeated measures analysis of variances from pre-treatment through follow-up. RESULTS Our CR intervention proved durable. Post-treatment improvements comprising cognitive flexibility, executive function, reaction time and working memory were maintained over the follow-up period. CONCLUSIONS Results confirm previous research regarding the durability of CR treatment and extend these findings to youth with 22q11DS. The present study may serve to inform early intervention efforts focused on cognitive and functionally relevant rehabilitation goals for youth with 22q11DS and suggests that 22q11DS can potentially serve as a suitable model for examining the trajectory preceding psychosis.

Abstract
Background Cognitive problems in people with schizophrenia predict poor functional recovery even with the best possible rehabilitation opportunities and optimal medication. A psychological treatment known as cognitive remediation therapy (CRT) aims to improve cognition in neuropsychiatric disorders, with the ultimate goal of improving functional recovery. Studies suggest that intervening early in the course of the disorder will have the most benefit, so this study will be based in early intervention services, which treat individuals in the first few years following the onset of the disorder. The overall aim is to investigate different methods of CRT. Methods This is a multicentre, randomised, single-blinded, controlled trial based in early intervention services in National Health Service Mental Health Trusts in six English research sites. Three different methods of providing CRT (intensive, group, and independent) will be compared with treatment as usual. We will recruit 720 service users aged between 16 and 45 over 3 years who have a research diagnosis of non-affective psychosis and will be at least 3 months from the onset of the first episode of psychosis. The primary outcome measure will be the degree to which participants have achieved their stated goals using the Goal Attainment Scale. Secondary outcome measures will include improvements in cognitive function, social function, self-esteem, and clinical symptoms. Discussion It has already been established that cognitive remediation improves cognitive function in people with schizophrenia. Successful implementation in mental health services has the potential to change the recovery trajectory of individuals with schizophrenia-spectrum disorders. However, the best mode of implementation, in terms of efficacy, service user and team preference, and cost-effectiveness is still unclear. The CIRCuiTS trial will provide guidance for a large-scale roll-out of CRT to mental health services where cognitive difficulties impact recovery and resilience.

Abstract
Cognitive deficits are one of the core symptoms of schizophrenia that evolve during the course of schizophrenia, after being originated even before the onset of illness. Existing pharmacological and biological treatment modalities fall short to meet the needs to improve the cognitive symptoms; hence, various cognitive remediation strategies have been adopted to address these deficits. Research evidences suggest that cognitive remediation measures improve the functioning, limit disability bettering the quality of life. The functional outcomes of cognitive remediation in schizophrenia are resultant of neurobiological changes in specific brain areas. Recent years witnessed significant innovations in cognitive remediation strategies in schizophrenia. This comprehensive review highlights the biological correlates of cognitive deficits in schizophrenia and the remedial measures with evidence base.

Abstract
Background: Accumulating evidence indicates that cognitive remediation (CR) is effective for improving various cognitive deficits in adult patients with schizophrenia. Although reports of brain plasticity in older adults and the service needs for chronic patients with schizophrenia are increasing, very few randomized controlled trials of CR have been conducted in middle-aged or older inpatients with chronic schizophrenia. We investigated the efficacy of individualized CR on the cognitive impairments of middle-aged or older inpatients with chronic schizophrenia within the context of comprehensive psychiatric rehabilitation (PR) by comparing the results obtained with PR only and treatment as usual (TAU). Method: Fifty-seven middle-aged and older individuals with chronic schizophrenia and mild to moderate cognitive deficits were enrolled. Thirty-eight who were undergoing PR were randomly assigned to CR + PR (N = 19) or PR-only (N = 19) groups. Nineteen participants who were undergoing TAU without CR or PR were evaluated pre- and post-treatment. Results: CR was easily provided and well received (drop-out rates = 5.3%) by middle-aged or older psychiatric inpatients. Compared to the PR-Only or TAU patients, patients in the CR + PR group showed greater improvement in executive functioning. Compared to TAU patients, CR + PR and PR-only patients showed greater improvement in logical memory. More patients in the CR + PR group improved clinically significantly in executive functioning and logical memory, compared with the PR-only and TAU patients. Conclusions: These results suggested that CR improved some cognitive deficits in middle-aged or older inpatients with chronic schizophrenia and that it was effective as an adjunctive treatment to the usual PR services provided in inpatient settings. Clinical Registration: KCT0002609.

Abstract
Cognitive symptoms play a central role in schizophrenia and are strongly associated with social functioning. Treatment with clozapine presents controversial results regarding its effects on cognition. The opposite effects of clozapine and n-desmethylclozapine (NDMC) on cholinergic system have been suggested to underlie these inconclusive findings. The aim of this study is to determine whether clozapine/NDMC ratio can predict cognitive performance in patients with treatment-resistant psychosis. Nineteen clinically stable patients with schizophrenia or schizoaffective disorder treated with clozapine monotherapy completed demographic and clinical interviews. For the purpose of the study, patients were assessed with a neuropsychological battery and on the same day a blood sampling was obtained from each patient to measure plasma levels of clozapine and NDMC. Our results showed that clozapine/NDMC ratio, but not clozapine or NDMC plasma levels separately, was a predictive factor of cognitive performance, specifically of executive functioning. Our results showed that lower clozapine/NDMC ratios are associated with better executive functioning in clinically stable patients. These findings could be interpreted by the different pharmacodynamic properties on cholinergic, dopaminergic and serotonergic systems of NDMC compared to clozapine.

Abstract
The durability of computer-assisted cognitive remediation (CACR) therapy over time and the cost-effectiveness of treatment remains unclear. The aim of the current study is to investigate the effectiveness of CACR and to examine the use and cost of acute psychiatric admissions before and after of CACR. Sixty-seven participants were initially recruited. For the follow-up study a total of 33 participants were enrolled, 20 to the CACR condition group and 13 to the active control condition group. All participants were assessed at baseline, post-therapy and 12 months post-therapy on neuropsychology, QoL and self-esteem measurements. The use and cost of acute psychiatric admissions were collected retrospectively at four assessment points: baseline, 12 months post-therapy, 24 months post-therapy, and 36 months post-therapy. The results indicated that treatment effectiveness persisted in the CACR group one year post-therapy on neuropsychological and well-being outcomes. The CACR group showed a clear decrease in the use of acute psychiatric admissions at 12, 24 and 36 months post-therapy, which lowered the global costs the acute psychiatric admissions at 12, 24 and 36 months post-therapy. The CACR is durable over at least a 12-month period, and CACR may be helping to reduce health care costs for schizophrenia patients.

Abstract
This study aimed to test how an 8-week training using computerized cognitive remediation therapy (CCRT) would modify resting brain functional activity and improve cognitive function in patients with schizophrenia. Twenty-seven patients with schizophrenia were recruited and randomized into two groups: CCRT or treatment-as-usual (TAU). The CCRT group received 40 sessions of computerized cognitive training over an eight-week period. There was a significant treatment group × time interaction on the processing speed (trail making test: F = 8.14, P = 0.01) and a trend in problem solving (mazes test: P = 0.06). Post-hoc tests showed that CCRT but not TAU significantly improved scores from baseline to end-of-treatment on these two cognitive assessments. For the resting brain functional activity, significant group × time interaction effect was found in the medial prefrontal cortex (mPFC)/anterior cingulate cortex (ACC) and brainstem pons region. Post-hoc tests showed that there was significant increased activity in the mPFC/ACC in CCRT but not TAU group. In this small sample study, computerized cognitive remediation therapy is shown to enhance mPFC/ACC activity even at resting state and improve cognitive function in patients with schizophrenia. If replicated, this community and clinic accessible therapy may assist cognitive remediation effort for people with schizophrenia.

Abstract
INTRODUCTION Individuals with psychotic disorders experience profound impairment in neurocognition, which is consistently found to be the best predictor of independent community functioning. Several diverse behavioural treatments designed to enhance neurocognitive abilities have been developed, with subtle to stark differences among them. Various approaches, to varying degrees, have demonstrated success across diffuse outcomes: improved brain structure and function, performance on neuropsychological tests, and community activities associated with daily living. Areas covered: This paper reviews the different approaches to cognitive remediation and the differential effects these approaches have on neurophysiological function, neurocognitive abilities, and real-world community functioning. Cognitive remediation approaches can be broadly classified along two dimensions: 1) treatment target, and 2) treatment modality. Some approaches target more basic perceptual skills, some target higher level executive processes, while some are non-targeted and seek to improve general cognitive ability. With regard to modality, approaches might have little/no therapist involvement and rely exclusively on computerized practice or they may include intensive therapist involvment to generalize neurocognitive change to community functioning. Expert commentary: Compared to other widely implemented treatments for schizophrenia, cognitive remediation produces better effects on outcome measures. It is time for cognitive remediation to be adopted as a best practice in the treatment of schizophrenia.

Abstract
This paper examines the evidence that delusions can be explained within the framework of a neurocognitive model of how the brain assesses certainty. Here, 'certainty' refers to both low-level interpretations of one's environment and high-level (conscious) appraisals of one's beliefs and experiences. A model is proposed explaining how the brain systems responsible for assigning certainty might dysfunction, contributing to the cause and maintenance of delusional beliefs. It is suggested that delusions arise through a combination of perturbed striatal dopamine and aberrant salience as well as cognitive biases such as the tendency to jump to conclusions (JTC) and hypersalience of evidence-hypothesis matches. The role of emotion, stress, trauma and sociocultural factors in forming and modifying delusions is also considered. Understanding the mechanisms involved in forming and maintaining delusions has important clinical implications, as interventions that improve cognitive flexibility (e.g. cognitive remediation therapy and mindfulness training) could potentially attenuate neurocognitive processes.
