Abstract (eng)
The person's subjective perception of its wellbeing is a central aspect in evaluating a therapy. Health-related quality of life (HRQoL), depression and self-efficacy of substance dependent delinquents, who participated in a quasi-compulsory therapy (QCT), were assessed at the institution P.A.S.S in Vienna, Austria. A total of 34 patients completed two questionnaires, the German version of the Short Form-36 Health Survey (SF-36) and the Nottingham Health Profile (NHP), to determine the HRQoL. To assess depression and self-efficacy the Becks Depression Inventory and the General Perceived Self-Efficacy Scale were used. At the beginning of the therapy HRQoL and depression were significantly lower compared to the sample of the standard population. After seven weeks of therapy an increase in almost all subscales of HRQoL and depression was observed. The discriminative and psychometric properties of the NHP and SF-36 were assessed using the discriminative validity, receiver operating characteristic (ROC) analysis, the selectivities as well as floor- and ceiling effects. The SF-36 had an overall better performance. To sum up, the evaluation of the QCT showed a positive impact on HRQoL and depression of the participants, despite the fact of coercion.
