Schools are the most common venue for youth mental health services, but school mental health (SMH) typically does not use evidence-based clinical interventions (CI), common elements of effective mental health, or effective implementation strategies. To address this gap, a multidisciplinary team developed the Brief Intervention for School Clinicians (BRISC), a four-session engagement, brief intervention, and triage strategy targeting a range of mental health (e.g., anxiety, depression, past trauma) and other problems (academic, peer, family). BRISC outperformed SMH usual care on engagement, treatment completion, and youth self-reported problem severity. Although there are many evidence-based SMH strategies such as BRISC, integration into practice is poor because accompanying implementation strategies are often absent, poorly defined, or insufficiently tailored to the education context.
