Trajectories of occupational and social functioning in people with recent-onset non-affective psychosis enrolled in specialized early intervention services across New York state

Background: Despite the benefits of early intervention services for the initial stages of psychosis ongoing impairments in functioning are common. Aims: To identify 1-year trajectories of occupational and social functioning in individuals enrolled in OnTrackNY, a statewide program offering early intervention services for recent-onset psychosis in community settings. Method: We included 937 persons with recent-onset psychosis enrolled at 19 programs across New York State. Demographic, social and clinical data was collected at program entry and at 3, 6, 9 and 12 months. We used growth mixture models to identify occupational and social functioning trajectories and examined the association between trajectory class, baseline factors and symptoms during 1-year follow-up. Results: Four distinct trajectory classes of occupational and social functioning were identified. The converging (58.0%) class had disparate levels of functioning at baseline (low occupational, higher social) which eventually converged. The other classes had high-stable (14.8%), moderate-stable (17.8%) and low-improving (9.4%) trajectories. Female gender, educational attainment and private insurance status were significantly associated with the trajectory characterized by higher functioning, while living alone, homelessness, a longer period from psychosis onset to program enrollment, a schizophrenia diagnosis and cannabis use at enrollment were associated with the poorest trajectory. The differences in severity of symptoms by trajectory class diminished over time. Conclusions: Trajectories of occupational and social functioning showed substantial variation, but overall, remained stable or improved during 1-year follow-up. The relationship between symptoms and occupational and social functioning attenuated after the acute treatment phase.
