In Germany methodologically reliable procedures to assess patients satisfaction with inpatient health care are almost totally missing. With reference to the well known American CSQ-Questionnaire (Attkisson et al.) a 17-items questionnaire (to assess satisfaction) was developed and presented to a sample of 300 patients undergoing inpatient treatment within a psychosomatic clinic (the rate of responding was about 80%). With a concise form of the questionnaire (Zuf-8, 8 items) an economical and reliable test-instrument is presented in this paper to measure general satisfaction, which also was investigated in regard to item- and factor analysis. This method seems suitable for measuring patient satisfaction with inpatient psychosomatic treatment. The investigated scales of satisfaction show a statistically significant correlation with additionally obtained patient characteristics. This inquiry also suggests that it might be rewarding to pursue the often neglected phenomenon of questionnaires filled out incomplete as an indicator of latent dissatisfaction.
