The Bahamian Ministry of Education has elected to implement at a national level in all Bahamian government grade six classes an evidence-based HIV prevention intervention [Focus on Youth in the Caribbean (FOYC)]. This study explores fidelity of implementation of the intervention, factors that may influence implementation fidelity, and the impact of variations in the implementation fidelity on student outcomes. Data were collected in the first wave of national implementation in 2011, involving 35 government primary schools and 110 teachers and 2,811 students. Structural equation modeling was performed to examine the relationships among factors which facilitated or impeded teachers’ implementation of FOYC. Results indicate that teachers taught 16.3 out of 30 core activities, 24.9 out of 46 total activities, and 4.4 out of 8 sessions on average. The strongest predictor of implementation fidelity was teacher comfort level with the FOYC curriculum. Teachers who did not perceive the FOYC intervention to be important for their students or who had attended only part of a FOYC training workshop were more likely to change the curriculum. Increased duration of experience as a teacher (>10 years) was negatively associated with fidelity of implementation. Teacher’s perception of the importance of the FOYC intervention and implementation fidelity had direct positive effects on students’ HIV/AIDS knowledge, reproductive health skills, protective intentions, and self-efficacy. Youth did not appear to benefit from FOYC if two or fewer sessions were delivered. We concluded that an evidence-based HIV prevention intervention can be implemented at a national level. Prior training of teachers in the intervention curriculum, teacher perception of the importance of the intervention, and fewer years as a teacher are associated with implementation fidelity. Implementation fidelity is associated with improved student outcomes.
