Bridges2Scale: Testing Implementation Strategies

The goal of this clinical trial is to compare two multifaceted strategies (standard vs enhanced) for scaling Bridges in a two-arm Hybrid III effectiveness-implementation cluster randomized controlled trial (RCT) in adolescent and youths affected by AIDS \[AYaAIDS\] (ages 11-17 years) from 48 schools in the Greater Masaka region of Uganda. The main aims of the clinical trial are: Aim 1. Compare the implementation effectiveness of the standard implementation strategy vs. an enhanced implementation strategy. The investigators will assess fidelity to Bridges (primary implementation outcome) and sustainment of Bridges (exploratory implementation outcome). Aim 2. Determine the clinical effectiveness of Bridges implemented via a standard vs. enhanced implementation strategy. Aim 3: Explore implementation processes, mechanisms, and determinants. Aim 4. Compare the cost and cost-effectiveness of the two implementation strategies. Using an activity-based ingredients approach, the investigators will examine how much each strategy costs to achieve a unit of effect.
