Abstract
Objectives. To examine quality of life and subjective well-being as predictors of symptomatic treatment outcome. Methods. Biweekly PANSS ratings were performed in 285 inpatients with schizophrenia spectrum disorders within a multicenter trial by the German Research Network on Schizophrenia. Quality of life and subjective well-being were assessed using the Medical Outcomes Study-Short Form 36-Item Health Survey (SF-36), the Subjective Well-being Under Neuroleptic Treatment Scale (SWN-K) and the Adjective Mood Scale (AMS). Response was defined as an initial 20% PANSS total score reduction and remission according to the consensus criteria. Correlation analysis, logistic regression and CART-analysis were performed. Results. In total, 81% of the sample achieved symptom response and 48% symptom remission. The statistical analyses revealed early improvement within the first two treatment weeks in the SWN-K scale to be a significant predictor for symptomatic response. Concerning symptomatic remission the SF-36 and SWN-K baseline scores as well as SWN-K early improvement showed significant predictive value. Conclusions. These results highlight the importance of the patient's self-perception and especially of early improvement of quality of life and subjective well-being for symptomatic treatment outcome.
