Conversely, the Self-Rating Anxiety Scale was employed to evaluate the subjective experience of anxiety in patients and to monitor its alteration throughout the therapeutic process. The Self-Rating Depression Scale is a self-assessment tool designed to measure the severity of depressive states and track changes during treatment. SAS: Self-Rating Anxiety Scale; SDS: Self-Rating Depression Scale.
