Prediction of hospitalizations by schizophrenia patients' assessment of treatment: an expanded study.

This study examines whether schizophrenia patients' global assessment of treatment predicts outcome in community care. Eighty-five patients rated the extent to which their treatment was right for them. The outcome measure was assessed by means of a hospitalization index reflecting the duration of full and partial hospitalization within a follow-up period of 24 months. Patients who dropped out (n = 21) assessed their treatment more negatively than those who remained in the care system during follow-up. Patients with no hospitalization (n = 25) expressed a more negative assessment than patients who were hospitalized in the follow-up period at least once (n = 39). In this latter subgroup, however, patients with a more negative assessment had a longer duration of hospitalization during follow-up, and patients' assessment of treatment was the best single predictor of outcome (r = -0.50, P < 0.01). In a multiple regression analysis, patients' assessment of treatment, the number of previous hospitalizations and the hospitalization index in the two years prior to the interview, together, explained approximately half of the variance of outcome (adjusted R2 = 0.46). The findings underline the relevance of asking patients whether treatment is right for them, although the relationship between patients' assessment of treatment and long-term outcome seems more complex than previous studies suggested.
