Inpatients' assessment of outcome at psychiatric institutions: an analysis of predictors following a national cross-sectional survey in Norway.

Self-perceived mental health before admission, current overall state and type of admission were the most important background factors for patient-assessed outcome. The most important structure and process variables were related to patient-centred interaction. The background factors should be considered in case-mix adjustments of quality indicators, while the process variables could be used as focus areas in work aiming to improve patients' assessment of outcome.
