Nomophobia (no mobile phone phobia) is a term used to describe discomfort or anxiety experienced when individuals are unable to use or access their mobile phones. Although not formally recognized in the DSM-5 or ICD-11, nomophobia has gained increasing research attention. The present study systematically reviewed and meta-analyzed the global prevalence of nomophobia, based on 43 studies (n = 36,656 participants) from 18 countries. Only studies using validated self-report instruments, primarily the Nomophobia Questionnaire (NMP-Q), were included. Subgroup analysis and meta-regression were conducted to determine the sources of heterogeneity. Results indicated that nomophobia is widespread, with 26 % of participants reporting mild symptoms, 51 % moderate symptoms, and 21 % severe symptoms. Importantly, these figures reflect self-reported levels of distress rather than clinical diagnoses. Higher prevalence was observed among university students and young adults. The wide variation across regions and instruments suggests nomophobia is influenced by cultural, behavioral, and technological contexts. Despite ongoing debates regarding whether nomophobia is an anxiety disorder, these findings highlight the critical need for precise definitions and continued exploration of its psychological correlates.

Nomophobia and social anxiety have significant negative implications for the physical and mental health of students, as well as their academic performance. Considering the variability in findings across studies on the prevalence of nomophobia and social anxiety, this study aimed to investigate the prevalence of nomophobia, its associated factors, and its relationship with social interaction anxiety among nursing students.

This cross-sectional descriptive-analytical study was conducted between August 22nd and September 23rd, 2023, at the School of Nursing and Midwifery in Kermanshah, located in western Iran. A convenience sampling method was employed, resulting in the recruitment of 258 participants. Data were collected using a three-part questionnaire, including a demographic information form, the Nomophobia Questionnaire (NMP-Q) to assess the severity of nomophobia, and the Social Interaction Anxiety Scale (SIAS) to measure social anxiety levels. Data were analyzed using STATA, version 14. Descriptive statistics were used to summarize demographic and clinical characteristics. The Chi-square test, one-way analysis of variance, the Pearson correlation coefficient, and linear regression modeling were employed for inferential analysis.

All participating nursing students (n = 258) exhibited some degree of nomophobia. The prevalence of mild, moderate, and severe nomophobia was 40.7%, 40.3%, and 19%, respectively. Furthermore, 25.6% of the students experienced social anxiety. A significant positive correlation was found between nomophobia scores and social interaction anxiety (r =.37, P <.001). Social interaction anxiety emerged as the only significant independent predictor of nomophobia (P <.001), explaining 21% of the variance in nomophobia scores.

The results indicate both the prevalence of nomophobia and social anxiety, as well as the correlation between these two factors among students. Considering the numerous risks associated with nomophobia and social interaction anxiety, it is essential to optimize technology use and improve social interactions among students. Identifying students at risk of nomophobia and social interaction anxiety and providing psychological counseling services to them should be prioritized.

The rise in smartphone use and the resulting dependence has led to the emergence of nomophobia, a term describing the anxiety or discomfort experienced when individuals are without their mobile phones. This study aimed to examine the prevalence of nomophobia among adults in Cyprus and explore its relationship with demographic characteristics, reasons for smartphone use, and coping styles.

In line with this aim, participants were 300 adults from Cyprus recruited by convenience and snowball sampling methods. The data were collected via an internet-based questionnaire that examined participants' level of nomophobia, reasons for phone use, time spent on their phones, and coping styles. The study utilized a Personal Information Form, the Nomophobia Questionnaire (NMP-Q), and the Brief Coping to Problems Experienced Inventory (Brief COPE) to gather data.

The results suggest that (a) nearly all participants (99.3%) exhibited some level of nomophobia, with more than half of our sample (51.3%) experiencing moderate levels, (b) younger adults, women, and individuals with lower education levels were more prone to nomophobia, (c) communication and social media were positively related to nomophobia, and (d) maladaptive and avoidant coping strategies exacerbated the severity of nomophobia.

The findings highlight the growing concern of nomophobia and stress the need for educational programs promoting healthier smartphone habits.

Smartphones have become an indispensable part of people's lives, and the fear of being without them, what has been termed "no mobile phone phobia" (nomophobia), is a growing phenomenon. The rise of problematic smartphone use highlights the urgent need to explore the intricate relationship between smartphones and human behavior. However, the connections between nomophobia, mental health indicators, smartphone use patterns, and daily activities remain largely underexplored.

This study aimed to explore the relationship between young adults with depression and smartphones and investigate nomophobia by analyzing data obtained from a pilot study of depression in a youth cohort. Exploring nomophobia can enhance our understanding of the dynamics between young adults and smartphone use, potentially empowering them to manage and regulate their smartphone use more effectively.

During an 8-week period, data collected via smartphone sensors, such as locations and screen status, were gathered from a cohort of 41 individuals diagnosed with major depressive disorder. In addition to passive-sensing smartphone data, the study collected ecological momentary assessments and psychometric measures, including the Nomophobia Questionnaire, which formed the basis of our investigation. We explored statistical associations among smartphone-derived behavioral features, psychometric indicators, and nomophobia. In addition, we used behavioral and psychometric data to develop regression models demonstrating the prediction of nomophobia levels.

Our findings revealed that the level of nomophobia was positively associated with depression and negative affect, lower geolocation movements, and higher comfort with smartphone sensing. The exploratory predictive linear regression models demonstrated the feasibility of predicting an individual's Nomophobia Questionnaire score based on their smartphone sensing data. These models effectively used input features derived from both a combination of smartphone sensing data and psychometric measures and from smartphone sensing data alone.

Our work is the first to explore the relationship between nomophobia and smartphone sensor data. It provides valuable insights into the predictors of nomophobia level, contributing to the understanding of the relationship between smartphones and human behavior and paving the way for future studies.

The advent of the metaverse, including virtual reality, augmented reality, and artificial intelligence, is an undeniable issue that health care scientists need to update. It influences all fields of knowledge, interpersonal relationships, and health. Regarding mental health since the post-coronavirus disease 2019 pandemic, it is necessary to consider and understand the potential, possibilities, weaknesses, and consequences arising from and provided by this new scenario. Due to the increasing need for mental health monitoring and care, mental health treatments require in-depth training and preparation to achieve the maximum use of the metaverse advantages and possibilities. Currently, very little is known about the effectiveness of remote mental health treatment, but it is certainly suggested that accessibility and the characteristics associated with the use of metaverse technologies may represent new horizons for accessibility and approach tools, as long as more studies are carried out and more evidence is collected to develop accurate guidelines, safe training, solve ethical concerns, and overcome limitations.

Nomophobia is a public health issue that involves the fear of being without a mobile phone. The study aimed to estimate the prevalence of nomophobia and its relation to psychological factors, including depression and insomnia, among the general population in Makkah Province and Al-Madinah Province, Saudi Arabia.

This analytical cross-sectional study was conducted and data were obtained through a self-administered online questionnaire using the Patient Health Questionnaire-2 (PHQ-2) for depression, the Nomophobia Questionnaire (NMP-Q), and Insomnia Severity Index (ISI).

A total of 1022 participants completed the questionnaire. The prevalence of nomophobia was 96.7%. Moderate nomophobia was prevalent (47.8%). Based on the PHQ-2, possible depression was identified in 47.3% of the respondents. 37.1% had sub-threshold insomnia. In terms of personal psychiatric history, the most common mental disorders in the participants included generalized anxiety disorder (9.9%) and major depressive disorder (9.7%). 61.6% of them used mobile devices for more than four hours per day.

Nomophobia is prevalent in the Makkah and Al-Madinah provinces in Saudi Arabia. The risk of nomophobia was significantly higher for participants who spent more hours using mobile devices, those with possible depression, and those having irritable bowel syndrome.

Today, adolescents tend to accept smartphones more quickly than adults and spend more time with these devices since they are members of the first generation born and living in environments where smartphones and the internet are common. However, when they use smartphones excessively and become addicted to smartphones, this may cause them to suffer from various psychological, emotional, and physical health problems from an early age. Therefore, this study systematically examines the articles on smartphone addiction in adolescents. For this purpose, the related articles were screened using the Web of Science database and 188 studies by the search criteria were subjected to a systematic review. In this sense, methodological tendencies, variables and main findings of the studies included in the present study were examined. This study revealed that the quantitative research method was primarily used. The studies mainly investigated smartphone use, social relations, demographic characteristics, depression, personal characteristics, and sleep variables. Moreover, the studies were primarily conducted in China, and large sample groups were preferred. The factors that triggered the smartphone addiction of adolescents were family problems, and especially females were more addicted to smartphones than males. Moreover, smartphone addiction causes depressive symptoms, sleep problems, and decreased academic achievement in adolescents. Finally, various suggestions were presented based on the findings of this study.

Nomophobia ('no mobile phone phobia') has been growing issue worldwide in recent years and has been associated with a number of psychological and behavioral health-related problems. However, few studies have examined nomophobia in Bangladesh. Therefore, the severity and correlates of nomophobia, and the mediating role of smartphone use between Facebook addiction and nomophobia was investigated. A cross-sectional study utilizing 585 university students was conducted employing a convenience sampling method. Data were collected using a survey in March 2022. The survey comprised questions related to socio-demographics, behavioral health, academic performance, nomophobia, smartphone addiction, Facebook addiction, insomnia, and depression. The mean score of nomophobia was 88.55 out of 140 (±21.71). The prevalence was 9.4% for mild nomophobia, 56.1% for moderate nomophobia, and 34.5% for severe nomophobia. First-year students had higher levels of nomophobia than other years. Significant predictors for nomophobia included daily duration of smartphone time, psychoactive substance use, and being in a relationship. Nomophobia was significantly associated with smartphone addiction, Facebook addiction, insomnia, and depression. Moreover, smartphone addiction significantly mediated the relationship between Facebook addiction and nomophobia. Strategies that help reduce daily smartphone time, and reduce psychoactive substance use might help reduce nomophobia prevalence among university students.

The standard of care among youth who are psychiatrically hospitalized typically involves smartphone confiscation for the duration of treatment. However, very little is known regarding how youth respond to this period of smartphone "deprivation," factors that may influence this response, and ensuing clinical effects. The present exploratory mixed-methods study sought to elucidate the experience of psychiatrically hospitalized adolescents as it relates to smartphone deprivation, and to evaluate the impact of this widespread treatment approach. Psychiatrically hospitalized adolescents (N = 181; Mean age = 15.29 years) completed qualitative and quantitative measures assessing the experience of smartphone deprivation during hospitalization. Associations among reactions to smartphone deprivation and smartphone and social media use patterns were explored. Analyses additionally evaluated whether reactions to smartphone deprivation were associated with clinical symptom severity (e.g., suicidal ideation, internalizing and externalizing symptoms) and readiness for psychotherapy. Negative reactions to smartphone deprivation were significantly positively correlated with daily smartphone hours, addictive patterns of use, and both negative and positive emotional responses to social media use. Reactions to smartphone deprivation were not associated with clinical symptom severity. However, negative reactions to smartphone deprivation were associated with lower readiness for therapy, while positive reactions were associated with greater readiness. This preliminary work illustrates the complexities of smartphone use in adolescents and the potential positive and negative effects of smartphone deprivation during psychiatric hospitalization. Future prospective research with adolescents should clarify optimal smartphone access during inpatient hospitalization.

Nomophobia is the discomfort caused by not being in contact with a cell phone. Few studies have addressed nomophobia in university students. The study aimed to evaluate nomophobia and its associated factors in Peruvian medical students. We conducted an analytical cross-sectional study on Peruvian medical students between June 2020 and March 2021, using an online survey disseminated through social networks. We analyzed 3139 responses (females: 61.1%, median age: 22 years): 25.7% presented moderate nomophobia and 7.4% severe nomophobia. In the adjusted model, the nomophobia score was lower in students ≥24 years (β: −4.1, 95% CI: −7.2 to −1.0) and was higher in those who had a mobile internet data plan (β: 2.9, 0.8 to 5.0), used the cell phone >4 h (β: 4.5, 2.3 to 6.7), used a smartphone mainly for education (β: 2.5, 0.2 to 4.8), social networks (β: 8.2, 5.8 to 10.6) and entertainment (β: 3.3, 0.5 to 6.1), and those who presented possible anxious (β: 6.6, 4.3 to 8.9) or depressive (β: 19.5, 5.2 to 9.6) symptomatology. In conclusion, nomophobia in university students is a frequent and emerging problem, present mainly at younger ages and associated with symptoms of anxiety or depression. Implementing evaluation and early intervention strategies would favor the mental health of university students.

The present study aimed at investigating nomophobia prevalence, thus, recurrence of anxiety without a smartphone, with preservice teachers in the Colleges of Education, Ghana. An actual sample of 345 preservice teachers responded to a 20-item questionnaire on nomophobia (NMP-Q). A one-way MANOVA between different groups statistics was applied in determining the differences in nomophobic behaviours among preservice teachers based on non-technology-related variables (gender, age, specialism, subjective economic status, sleep/rest hours, and religion) and technology-related variables (number of smartphones owned, smartphone ownership duration, active internet services, and daily internet usage time). The results evidenced that the vast majority of preservice teachers had mild to severe nomophobia, and their most significant anxiety was related to access to information and communication. Besides, non-technology-related variables in gender, sleep hours, and subjective economic status significantly impacted the preservice teachers' nomophobia. Technology-related variables that significantly influenced the nomophobic behaviour of preservice teachers included the number of smartphones owned, smartphone ownership duration, and active internet service. A sizable majority of the preservice teachers showed signs of mild to severe nomophobia. The present study provides prefatory support for the prevalence of nomophobia among the Ghanaian preservice teachers.

Nomophobia (no-mobile-phone phobia) is a relatively new term that describes the growing fear and anxiety associated with being without a mobile phone. Our study aims to determine the prevalence of nomophobia among the undergraduate students of Pakistan, and to determine its correlation with age and gender. It also aims to determine the contributory factors of nomophobia. A cross-sectional study was conducted through an online survey from March 25 to April 25, 2021. The snowball sampling technique was used for data collection. The Nomophobia Questionnaire (NMP-Q) developed by Yildirim and Correia was circulated among the target population. It was a 7-point Likert Scale that was analyzed on the basis of age and gender using IBM SPSS version 22 and MS Excel 2007. The contributing factors were also analyzed. Of the 483 responses we received, 28 were discarded due to incompleteness and respondents being out of age under study that is, 15-25 years. Most of the respondents were women (n = 314, 69.01 percent). Men were less in number than women (n = 141, 31 percent). The ages of most of the respondents lied between 15 and 25 years. Twenty was the mode age. One hundred eighty-six (40.88 percent) had severe, 221 (48.57 percent) had moderate, and 48 (10.55 percent) had mild nomophobia. Average factor-wise scores and individual item scores were also added. Our findings reached a conclusion that the majority of the undergraduate students in Pakistan suffer from nomophobia ranging from its mild to severe form. Nomophobia can possibly be included as a recognized phobia in the DSM. Wider research on the subject to investigate it further and evaluate the clinical significance should be done.

Nomophobia can be defined as a digital age phobia consisting of an excessive fear of being without a smartphone. Nomophobia negatively impacts physical and mental health, particularly in children and adolescents. This study aimed to test the factor structure and psychometric properties of the European Portuguese version of the Nomophobia Questionnaire for Adolescents (NMP-Q-A). Sample 1 comprised 338 adolescents (58.6% girls), with a mean age of 13.55 (SD = 2.07) years old, and was used to examine the factor structure of the NMP-Q-A, its psychometric properties and the association with other constructs. Sample 2 included 193 adolescents (53.9% boys), with a mean age of 13.61 (SD = 0.80) years old and was used to further test the NMP-Q-A factor structure. One higher-order factor with four lower-order factors structure revealed a good fit to the data in both samples. The NMP-Q-A showed good reliability, construct and concurrent validity. Girls showed higher nomophobia. Adolescents showing more nomophobia revealed more smartphone addiction and psychopathological symptoms and lower quality of life. The NMP-Q-A showed to be a valid and reliable measure to be used in clinical and educational settings.

NOMOPHOBIA (NO MObile PHone PhoBIA) or problematic smartphone use is a psychological disorder in which people are afraid of being cut off from their mobile phones. Currently, there has been no direct assessment of mobile phone screen size in the home setting and its effect on nomophobia and related symptoms, such as insomnia. Thus, we investigated the association between nomophobia, insomnia, and mobile phone screen size in a young adult population in Bahrain.

Using a descriptive, cross-sectional design, we surveyed participants aged 18 to 35 between August and September 2020 using an online questionnaire. Participants completed demographic questions and questions about personal mobile phones, the Nomophobia Questionnaire (NMP-Q), and the Insomnia Severity Index (ISI). The mobile phone screen size was determined using an open-source online database. Crude and adjusted regression analyses were fitted to examine the associations between the study variables.

A total of 549 individuals, 54% females, were included in the final analyses. One hundred and fourteen participants (21%) had severe nomophobia, and 81 (14%) had clinical insomnia. A strong positive pair-wise linear association was observed between NMP-Q and ISI β 0.15, P = 0.001. Age, sex, BMI, and mobile phone screen size showed no association with the NMP-Q.

Nomophobia is very prevalent in young adult men and women, and it is closely associated with insomnia, regardless of mobile phone screen size, suggesting that mobile phone screen size should not be used as a proxy for hazardous usage.
