Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Reduction in depressive symptoms, anxiety symptoms, and global psychological distress during the waiting period for outpatient psychotherapy through the use of the DiGA deprexis® under real-world clinical conditions. - Outcomes will be assessed using standardized self-report questionnaires administered at multiple assessment points. Across all trial arms, a baseline assessment will be conducted prior to randomization (T1) and a final assessment will take place after twelve weeks (T4). - In the supported intervention group (IG-A), additional interim assessments are carried out after four weeks (T2) and eight weeks (T3) to record longitudinal change during DiGA use. - In the unsupported intervention group (IG-B), assessments will take place exclusively at baseline (T1) and post-intervention (T4). • In the waitlist control group (CG), assessments will also take place at T1 and T4. Assessment Instruments (Self-Report Questionnaires) • Patient Health Questionnaire-9 (PHQ-9; Kroenke et al., 2001) to assess the severity of depressive symptoms • Generalized Anxiety Disorder Scale-7 (GAD-7; Spitzer et al., 2006) to assess the severity of anxiety symptoms • Symptom Checklist-90-R (SCL-90-R; Derogatis, 1994) to assess global psychological distress and subjective symptom-related functional impairment | — |
Secondary
| Measure | Time frame |
|---|---|
| Acceptance, usage, and dropout patterns during the twelve-week DiGA-intervention period. The following parameters will be assessed: • Acceptance of the DiGA (e.g., user satisfaction, perceived fit, and perceived usefulness) • Usage intensity and adherence (e.g., frequency and extent of engagement) • Dropout rates, including reasons for discontinuation of DiGA-usage • Subjectively perceived effects of and subjectively perceived burden related to the intervention Secondary outcomes are assessed using study-specific standardized self-report questionnaires and structured interviews developed specifically for the study. These study-specific instruments serve scientific purposes and will undergo psychometric evaluation within the study. Exploratory Outcomes • Comparison of supported versus unsupported DiGA utilization with respect to efficacy, adherence, and attrtion • Examination of potential moderators and predictor variables (e.g., sociodemographic characteristics, baseline symptom severity, and attitudes toward digital health applications) • Evaluation of the clinical and healthcare relevance of the DiGA as a bridging intervention during the waiting time for psychotherapy within routine care settings | — |
