Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of the study is to compare adherence to aftercare between Combined and Classic Aftercare. The outcome measured is the percentage of attended in-person aftercare appointments (GE) out of the total number of GE planned for the respective group. The number of completed GE will be documented for each participant in participant and counselor questionnaires during the final session, 6 months after the start of aftercare at T2. To test the equivalence hypothesis, the difference between the two groups should not exceed ± 7 percentage points. The aim is to evaluate whether combined aftercare leads to equivalent utilization as classic aftercare. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints will be assessed at T0 (clinic recruits only), T1, and T2, and include work ability (WAI), abstinence self-efficacy (HEISA-16), general self-efficacy (ASKU), and psychological well-being (PHQ-9). At T1, additional measures capture therapy history (abstinence duration, number of treatment attempts, type and duration of therapy) as well as consumption history and current use. At T2, study-specific questions on participation in counseling sessions (GE), consumption/relapse via the KDS follow-up questionnaire (Katamnesebogen), and treatment satisfaction using the DRV-Bund questionnaire (from “Caspar multimodal,” item 27 adapted) are collected. In addition, a voluntary interview consent at the end of the T2 questionnaire enables qualitative analyses on integrability, time investment, potential barriers, and app relevance, for which contact details (phone number, name, email) are recorded. | — |
