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.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
