RESUMEN
OBJECTIVE: The aim of the study was to examine the association between resource activation and treatment success in in-patient and day-care psychosomatic treatment. METHODS: 130 patients were examined at the beginning and at the end of their in-patient or day-care psychosomatic treatment. The change of resource realization (RES[1]) and different measures of therapeutic success (SCL-90-R[2], BDI-II[3], WHO-5-Q[4], GAS[5], retrospective success evaluation [6]) were assessed using standardized questionnaires. RESULTS: The results demonstrated a significant trans-diagnostic change in patients' resource realization, which correlated with different measures of mental health (SCL-90-R, BDI-II, WHO-5-Q). Resource realization at the beginning of the treatment and the process of resource activation (pre-post measure of resource realization) turned out to be relevant for predicting treatment success. Furthermore, mediation analysis shows that initiation of experiences of mastery (BSPR-P[7]) seems to be effective as a mediation process. CONCLUSION: The results show that resource realization improves during psychosomatic treatment and is associated with treatment success.
