METHODS: We chose a naturalistic design with one pre- and two postmeasurements: admission, discharge, and 1-year follow-up with a follow-up sample of 935 patients from five psychosomatic hospitals.We assessed the effectiveness of inpatient psychosomatic treatments with the Global Severity Index (GSI) of the SCL-90-R at admission (M = 1.20, SD = 0.68), discharge (M = 0.67, SD = 0.58), and 1-year follow-up (M = 0.83, SD = 0.68) as well as with the Veränderungsfragebogen des Erlebens und Verhaltens (VEV-K) at discharge (M = 125.42, SD = 27.27) and follow-up (M = 115.50, SD = 31.16). RESULTS: Significant improvements were shown in the GSI from admission to discharge (F = 802.70, df = 1, p
