A Latent Class Analysis of Personality Traits in Adults Experiencing Homelessness.

This study focuses on identifying distinct subgroups of adults experiencing past-year homelessness in the United States based on their endorsement of personality difficulties related to borderline personality disorder (BPD), schizotypal personality disorder (SPD), and antisocial personality disorder (ASPD). Using latent class analysis on nationally representative data (N = 704), four classes were identified: a uniformly severe class with high endorsement of all personality difficulties and behavioral health disorders; an impulsive/antisocial class with elevated antisocial traits and substance use disorders; a minimal impairment class with low personality difficulties and behavioral health conditions; and an identity diffusion/relational instability class with higher mood and anxiety disorders and suicide attempts. The findings highlight the heterogeneity of personality difficulties among people experiencing homelessness and their differential associations with behavioral health conditions, suggesting the need for tailored interventions that address these varied profiles. Limitations include reliance on self-reported traits, assessment of only three personality disorders, and the cross-sectional design, which precludes causal inferences.
