Brief Summary
This is a five-year hybrid type 3 effectiveness-implementation study evaluating multilevel strategies to sustain a nationwide implementation of an evidence-based HIV prevention curriculum in schools. Advanced machine learning methods are being used to enhance implementation strategies. A Sequential, Multiple Assignment, Randomized Trial (SMART) design will be employed.

Conditions
Outcome Measures
Primary Outcomes (8)
Fidelity of Implementation
Adherence to the core activities (number of core activities taught as intended)
Years 1, 2, 3, and 4
Sustainability
Teachers' continued implementation of the intervention with fidelity (at least 80% of core activities) and adherence to program principles across 4 years
Year 4
Sustainment determinants
The Sustainment Measurement System Scale (SMSS) is a 35-item instrument that evaluates sustainment determinants and outcomes (one sustainment outcome subscale and seven determinant domain subscales). Items are rated on a 5-point scale, from 1 = Little or no extent to 5 = Great extent. Subscale scores are calculated as the average of the items within the subscale, ranging from 1 to 5. Higher scores on all subscales indicate greater agreement with the subscale.
Years 1 and 3
Inner and outer context factors affecting implementation
The Program Sustainability Assessment Tools (PSAT) is an eight-domain, 40-item instrument that assesses a program's capacity for sustainability. Items are rated on a 7-point scale from 1 = Little or no extent to 7 = A very great extent. Scores are first averaged within each domain, and an overall sustainability score is calculated by averaging the domain scores (range: 1-7). Higher scores indicate a great level of sustainability capacity.
Yeasr 1 and 3
School implementation climate
The School Implementation Climate Scale (SICS) is a seven-domain, 21-item instrument assessing a school's climate for implementing an evidence-based practice. Items are rated on a 5-point scale (0 = Not at all; 4 = Very great extent). Scores are first averaged within each domain, and an overall sustainability score is calculated by averaging the domain scores (range: 0-4). Higher scores indicate a more favorable implementation climate.
Years 1 and 3
Condom use skills
The Condom-Use Skills Checklist is an 8-item scale assessing youth's understanding of correct condom use. Each item is answered True/False. Scores are calculated as the total number of correct responses. Scores range from 0 to 8, with higher scores indicating greater knowledge of condom-use skills.
Years 1, 2, 3, and 4
Self-efficacy
A 5-item self-efficacy for condom use scale will be utilized to assess students' self-perceived ability to use condoms. Items are rated on a 5-point scale (1 = Strongly disagree; 5 = Strongly agree). Scores are calculated as the average of all items, with a range of 1 to 5. Higher scores indicate greater self-efficacy for condom use.
Years 1, 2, 3, and 4
Condom use
Self-reported condom use in the last sexual intercourse and frequency of condom use in general (always, often, sometimes, or never)
Years 1, 2, 3, and 4
Secondary Outcomes (3)
Youth risk and protective behaviors
Years 1, 2, and 4
Youth sensation seeking
Years 1, 2, 3, and 4
Neighborhood risk
Years 1, 2, 3, and 4
Study Arms (3)
Stage 1
EXPERIMENTALAll grade six teachers will go through the Usual Implementation (UI) of FOYC+CImPACT (teacher training only in Year 1).
Stage 2
EXPERIMENTALBased on their performance in Year 1, teachers who do not meet the benchmark (implementing \> 80% of core activities) will be randomized to receive 1) "Biweekly Monitoring and Feedback (BMF)" or 2) "BMF+Site-Based Assistance Mentorship (SAM)." Responders (completing at least 80% of core activities) will continue with UI.
Stage 3
EXPERIMENTALAt the end of Year 2 (stage 2), the performance of the teachers in all three intervention arms will be assessed again. Non-responders in the UI arm will be re-randomized to receive either BMF or BMF+SAM. Non-responders in the BMF-only group will be re-randomized to receive BMF+SAM or BMF+enhanced SAM. Non-responders in the BMF+SAM group will receive BMF+enhanced SAM.
Interventions
School coordinators will monitor teachers' implementation progress biweekly and provide feedback to teachers.
High-performing teachers will serve as team leaders and guide non-responding teachers on preparation and planning. The team leader will promote group activities and enhance interaction among teachers in these meetings.
A FOYC coach (with FOYC implementation and training experience) will provide tailored in-person support, facilitate goal-setting, opportunities to interact with consultants, supportive text messaging, continuing education, networking strategies, and monthly check-ins.
Focus on Youth in the Caribbean (FOYC) is an evidence-based, eight-session life skills curriculum designed to reduce risk-taking behaviors related to HIV/STI transmission and teen pregnancy. Woven throughout FOYC is a decision-making model that provides guidance and practice in problem solving with a focus on how to obtain factual information on sexual health. CImPACT is a single-session intervention including a 24-min educational video filmed in The Bahamas. The video focuses on effective parent-adolescent communication and listening strategies related to difficult topics including "safe-sex" followed by two role-plays for the parent and youth, a discussion, and a condom demonstration.
Eligibility Criteria
You may qualify if:
- Grade 6 teachers who teach Health and Family Life Education (HFLE) and their classes in 65 government primary schools.
