Résumé

Objective
To investigate whether first-episode psychosis patients receiving extended early intervention had better functional outcomes than those in regular care and to examine the predictors of functional outcomes.

Methods
This is a randomized controlled single-blind trial of 220 patients randomized after 2 years of early intervention to receive early intervention or regular care for the subsequent 3 years. Outcomes included cumulative time in functional recovery during the 3-year trial assessed using the Social and Occupational Functioning Assessment Scale (SOFAS); and employment/education at last assessment which were, respectively, analyzed using multiple linear regression and logistic regression, accounting for well-known predictors. Linear mixed and generalized linear models were also used to examine the course of SOFAS and employment/education over the 3-year period.

Results
The extended early intervention and regular care groups did not differ on time in functional recovery (mean = 50.17 weeks, SD = 46.62 vs. mean = 46.18 weeks, SD = 51.54); percent employed/in school (60.4% vs. 68.8%) or change in SOFAS or employment/education status over time. SOFAS scores were stable between years 2 and 5. Individuals with longer periods of total symptom remission experienced significantly longer periods of functional recovery and were likelier to be employed/in school. Those who had completed high school were nine times likelier to be employed/studying.

Conclusion
Most individuals maintained functional gains accrued from 2 years of early intervention with no further improvement whether in extended early intervention or regular care. There was a gap between symptomatic and functional recovery, and one-third were unemployed/not in school at year 5. The lack of additional progress even in extended early intervention suggests that specific interventions addressing functional roles need to be provided beyond the first 2 years of early intervention. Sustaining symptom remission and high-school completion may be additional avenues for targeting functional recovery.
