Longitudinal interrelationships of mental health discrimination and stigma with housing and well-being outcomes in adults with mental illness and recent experience of homelessness

Rationale: Stigma and discrimination are negatively associated with social and health status. People who are homeless often experience systemic stigma and discrimination. Objective: In this study, we analyze the longitudinal interrelationships between the trajectories of housing (housing stability) and well-being outcomes (i.e., recovery, quality of life, and community functioning) and the trajectories of discrimination and stigma in a sample of adults with mental illness and recent experiences of homelessness in Toronto, Canada. We also examined the effect of the Housing First (HF) intervention on these interrelationships. Method: The Group-Based Trajectory Model was used to estimate the interrelationship (or intersections) between discrimination and stigma with housing stability, recovery, quality of life, and community functioning in 274 participants of the At Home/Chez Soi, phase 2, Toronto site randomized trial over a two-year follow-up period. Results: Three distinct trajectory groups were observed for discrimination (Low, Moderate decrease, and moderate increase), stigma (Low, Moderate, and High), recovery (Low, Moderate, and High), and the quality of life (Low, Moderate, and High). Two-trajectory groups (Low and High) were identified for housing stability and community functioning. The analyses showed that the trajectory groups for discrimination and stigma are strongly and contemporaneously interrelated with thetrajectory groups for housing stability, recovery, quality of life, and community functioning ability. The HF intervention had a mitigating effect on the changes across select trajectory groups, particularly for members of the Low and High discrimination and stigma trajectories group. Conclusion: Persistent mental health-related discrimination and stigma trajectories are longitudinally and contemporaneously interrelated with housing and well-being outcomes in persons experiencing mental illness and recent homelessness. These findings indicate the need for interventions and actions to reduce stigma toward thispopulation. Such interventions may improve housing stability, quality of life, mental health recovery, and community functioning.
