Trajectories of suicidality during a 2-year early-intervention program for first-episode psychosis: A longitudinal study

Abstract

Little is known about the individual course of suicidal ideations and attempts (i.e., suicidality) after treatment initiation. We examined the trajectories of suicidality and associated risk factors over a 2-year early intervention program for first-episode psychosis in 450 patients (age range 18–35 years at admission) consecutively admitted from 2003 to 2017. Suicidality was assessed via systematic file review, while sociodemographic and clinical variables were assessed at admission. Latent class growth modelling identified three trajectories: low (69.6 %), initially high (22.9 %), and persistently high (7.6 %) suicidality. Patients who were younger, lived alone and were diagnosed with affective psychosis were significantly more likely to follow the initially high trajectory. Patients who attempted suicide up to 3 months before admission, lived alone and presented lower levels of the PANSS excited factor were significantly more likely to follow the persistently high trajectory. Attempting suicide up to 3 months before admission distinguished persistently high and initially high suicidality trajectories. Suicide risk during early intervention program for first-episode psychosis is heterogenous, with acute and enduring suicidal risk, suggesting the need to adapt suicide prevention strategies to these different risk profiles.
