RecruitingBehavioural interventionAn Adaptive Intervention to Increase Engagement to Community-Based Care After an ED AdmissionThe goal of this study is to develop a feasible brief, family-based adaptive intervention, via SMART design, for youth with suicidal and non-suicidal self-injurious behavior (SSIB) to increase community-based mental health (MH) care attendance and reduce SSIB risk post emergency department (ED) admission. The intervention will focus to increase understanding on youth MH literacy, MH communication, and MH engagement. Integrating an adaptive intervention via a SMART design in the ED could address subsequent barriers to youth obtaining appropriate level of community-based MH care and therefore reduce ED readmissions.
