Incidence, prevalence, and trajectories of suicidal ideation among clients enrolled in early intervention services for first episode psychosis in New York State

Knowledge on how suicidal ideation (SI) varies following first episode psychosis (FEP) onset is scarce. We identified 1-year trajectories of SI and baseline predictors of emergent SI among all 1298 clients aged 16-30 years enrolled between October 2013-December 2018 in OnTrackNY, a program providing early intervention services for FEP across New York State. Clinicians recorded baseline clinical and sociodemographic variables and quarterly assessments of SI over a one-year follow-up. We examined baseline correlates of baseline SI and of 1-year SI trajectory. Among clients not reporting baseline SI, we examined predictors of subsequent emergent SI. Baseline SI was reported by 349 (26.9 %) clients and associated with schizoaffective disorder, previous self-injurious behavior, any alcohol or substance use, higher symptom severity, poorer social functioning, and Non-Hispanic White, Asian or Hispanic ethnoracial background. Two hundred and two (15.6 % overall) clients stopped being suicidal within 6 months of follow-up. Persistent SI was reported by 147 (11.3 % overall) clients and, among clients not discharged before one year of follow-up, was associated with schizoaffective disorder, any alcohol use, being female, and being Hispanic or White Non-Hispanic. Among 949 (73.1 %) clients not reporting baseline SI, subsequent emergent SI was reported by 139 (10.7 % overall) and predicted at baseline by schizoaffective disorder, higher symptom severity, recent homelessness, and not being Hispanic. In conclusion, SI is highly prevalent and varies markedly over time among FEP early intervention clients. These results highlight the importance of ongoing assessment for SI among individuals experiencing FEP - even in the absence of baseline SI.
