Stability of outcomes after 5 years of treatment in an early intervention programme

Aim It has been hypothesized that the first 5 years are critical in determining long-term recovery from psychotic disorders. We examine stability in recovery indices after 5 years for 56 patients treated in an early intervention programme for psychosis. Methods Assessments of symptom remission and functional recovery were carried out 5 and 10 years after initiation of treatment. Results Although overall rates of recovery were comparable at both times, there were significant changes for individuals reflecting both improvement and deterioration. Conclusions Evidence concerning the critical period hypothesis should examine stability in individuals rather than relying on cumulative indices.
