Youth Mental Health First Aid: Examining the Influence of Pre-Existing Attitudes and Knowledge on Training Effectiveness.

Youth Mental Health First Aid (YMHFA) is a gatekeeper training designed to assist professionals in their identification and response to youth mental illness. Despite widespread implementation, few studies have examined how individual-level trainee characteristics may impact the effectiveness of this training. In this study, we examined how pre-existing knowledge and attitudes about youth mental illness (measured prior to participation in the program) influenced training outcomes. We used a sample of 987 child-serving professionals who completed the YMHFA training program to identify demographic and work-related factors that predicted pre-existing attitudes and knowledge. The sample was then divided into two groups based on pre-existing attitudes and knowledge. We examined training effectiveness across four constructs: knowledge, confidence, intentions to intervene, and stigma. Findings indicate that gender and work-related characteristics were associated with pre-existing knowledge and attitudes about youth mental illness. The magnitude of training effectiveness varied across pre-existing attitudes and knowledge. Those participants with above average attitudes and knowledge benefited little from the program, suggesting that universal implementation of YMHFA may not be an efficient use of resources. Suggestions for a tiered implementation plan that prioritizes professionals most in need of the training are discussed.
