To provide access to timely youth psychiatric care, the Bridge Program: School-Based Psychiatry provides interim, school-based psychiatric services by child psychiatrists and psychiatric nurse case managers at no cost to families. In its first year, Bridge served 394 youths, mostly from economically disadvantaged backgrounds, within 10 days of referral. Parents and teachers reported significant reductions in symptoms and high ratings of satisfaction and social validity. In the present study, we examine these same indicators during Bridge's third year of implementation to examine Bridge's sustained effects. During its third year (January to June 2018), Bridge served 210 youths (the majority were from economically disadvantaged families) within 4 weeks of referral. Outcomes for youth symptoms, treatment adherence, and parent and school personnel satisfaction remained as strong or stronger compared to the first year. These findings demonstrate promise for Bridge's sustainability and provide implications for school-based providers.
