Little research has examined which individual factors may predict mental health court diversion outcome. Using data provided by a non-profit mental health services agency operating in the Durham Region in Ontario, this study examined 419 persons with mental illness participating in a post-charge diversion program. Socio-demographic and clinical characteristics were employed to investigate the relationship between clientspecific factors and level of program completion. Logistic regression results revealed that unemployment was a significant predictor of program completion. Employment and symptom severity were predictive of partial completion of court diversion. Additionally, participants who did not complete programming were more likely to have a concurrent disorder and were more likely to be residentially unstable than participants who did complete programming. These findings are discussed with respect to their implications for practice and future research.
