Evaluation of a Modularized Cognitive Behavioral Group Therapy Programme for Young Adults (CHANGE-Study)

This prospective, non-randomised, pre-post feasibility study evaluates CHANGE, a novel 8-session modularized cognitive behavioral group psychotherapy for young adults (18-25 years) with psychiatric disorders receiving inpatient or day-care treatment. All eligible participants (planned n=30) receive the intervention in addition to treatment-as-usual; there is no control arm. The primary aim is to assess feasibility, acceptability and appropriateness of the intervention (SMI (a German scale for feasibility), SAI (a German scale for acceptability), AIS (a German scale for appropriateness) scales; recruitment, retention, adherence and dropout rates). Secondary outcomes include perceived competence, self-efficacy (SWE), motivation (FEVER), satisfaction, quality of life (WHOQOL-BREF) and level of functioning (GAF), assessed before (T0) and after (T1) the intervention.
