Abstract
BACKGROUND: Schools are critical venues for supporting LGBTQ+ youth well-being. Implementing LGBTQ-supportive practices can decrease experiences of stigmatization, discrimination, and victimization that lead to adverse mental health outcomes like anxiety, depression, and suicidality. However, schools are also subject to a wide range of outer-context pressures that may influence their priorities and implementation of LGBTQ-supportive practices. We assessed the role of emergent outer-context determinants in the context of a 5-year cluster randomized controlled trial to study the implementation of LGBTQ-supportive evidence-informed practices (EIPs) in New Mexico high schools. METHOD: Using an iterative coding approach, we analyzed qualitative data from annual interviews with school professionals involved in EIP implementation efforts. RESULTS: The analysis yielded three categories of outer-context determinants that created challenges and opportunities for implementation: (a) social barriers related to heterocentrism, cisgenderism, and religious conservatism; (b) local, state, and national policy and political discourse; and (c) crisis events. CONCLUSIONS: By exploring the implications of outer-context determinants for the uptake of LGBTQ-supportive practices, we demonstrate that these elements are dynamic-not simply reducible to barriers or facilitators-and that assessing outer-context determinants shaping implementation environments is crucial for addressing LGBTQ health equity.
