The aim of this study was to investigate how self-assessments of perceived distress and quality of life in patients with schizopsychotic illness are associated with nurse assessments of symptoms, function and life situation. Data were obtained through interviews that used evidence-based rating and visual analogue self-rating scales. Descriptive statistics, correlation and regression analyses were used to process the data. The results demonstrated that the patient self-ratings did not correlate with the nurse assessments, and the perceived distress was not affected by remission status. The findings indicate that patient self-assessments are not a sufficient basis for decisions regarding appropriate treatment interventions.
