Adapting a youth suicide prevention program for rural communities in the United States: a feasibility study

Rural youth suicide represents a major source of mental health inequity in the United States (US). School-based suicide prevention programs may provide an effective avenue to address this mental health crisis among rural youth. This study's primary goal is to demonstrate the feasibility and acceptability of a novel implementation approach (utilizing teachers from a neighboring school) for delivering the Youth Aware of Mental Health (YAM) program, an evidence-based, universal youth suicide prevention curriculum, to high school students in rural Montana. We will recruit approximately 1300 9th grade student in four Montana schools. Using a non-inferiority design, we will randomize classrooms in each school to be instructed by a teacher from another school (YAM-TE; experimental) or a traditional external instructor (YAM-EXT; control). We will assess program fidelity of both YAM training and implementation via independent observer and instructor-reporter ratings. Youth will complete measures of acceptability at post-YAM and outcome measures at pre-YAM, post-YAM, and 12 month follow-up. Standard and mixed linear and logistic regression models will be used to test the main hypothesis that the YAM-TE does not differ from YAM-EXT regarding fidelity (teachers) and acceptability (teachers and youth). Exploratory analyses will test moderation of the intervention effect (e.g., sex, poverty) and the mediating effect of mental health literacy, belongingness, and perceived burdensomeness on the intervention effect. Results of this pilot study will inform the development of subsequent, fully powered noninferiority trials. Our long-term goal is to scale YAM-TE for implementation across rural US communities or, if culturally appropriate, more globally.
