Youth Mental Health First Aid (YMHFA) is an 8-hour program that introduces participants to risk factors and warning signs of mental health concerns in youth and teaches them how to help youth experiencing mental health challenges. Blended funding from Project Cal-Well, BlueSky, and Cal-STOP is supporting the statewide implementation of YMHFA trainings. Our School Health Evaluation and Research team provides YMHFA evaluation services to not only track the statewide reach of the training, but also to collect registration and follow-up survey data to document changes among training participants in confidence in supporting youth mental health.
