(PS5-D79) Exploration of Multi-level Determinants That Influence Peer Body Project Implementation: A Mixed Methods Study

Across university campuses, college students experience high rates of mental health challenges, with eating disorders as a top concern. Unfortunately, due to a variety of interrelated factors (i.e., determinants), many do not receive the evidence-based interventions (EBIs) that they need. Further, university mental health systems are complex, and it is unclear which determinants are most influential in EBI implementation. The Consolidated Framework for Implementation Research (CFIR) provides a systematic approach for researchers to identify the most salient constructs for successful implementation of EBPs (Damschroeder et al., 2009). To address this issue, the current mixed methods study examined implementation determinants of a peer-led, evidence-based prevention program, the Peer Body Project, across multiple levels of influence, including organizational outer setting determinants, organizational inner setting determinants, and provider characteristics in 62 universities. The following hypotheses guided analyses: (1) multiple organizational inner and outer setting determinants will be associated with implementation climate and (2) organizational outer and inner setting determinants will predict provider attitudes toward intervention characteristics. Peer Body Project supervisors (N = 62) from participating universities completed qualitative interviews and related questionnaires before program implementation. Data analyses included a bivariate correlation matrix and multiple regression. There were no significant correlations between the examined outer and inner setting determinants and implementation climate, and the examined outer and inner setting determinants did not significantly predict provider attitudes toward intervention characteristics. However, findings suggest leadership engagement is positively associated with provider access to knowledge and information, as well as to material resources. Implications for university mental health systems and future directions are discussed.
