Adapting Group PM+ for Venezuelan Refugees and Migrants in Colombia

This study is a type 2 hybrid implementation design, which aims to evaluate the utility and effectiveness of an intervention while simultaneously assessing implementation outcomes, such as adoption, fidelity, and maintenance. The aim is to compare participant level outcomes when the intervention is delivered by facilitators that are trained and supervised by psychologists versus by lay-supervisors. Group PM+ will be delivered to participants in two phases: first, with high levels of technical support through intensive training and supervision by mental health professionals and a second phase with routine service delivery and supervision. Non-specialist community members who are trained and supervised by psychologists to deliver PM+ as part of Phase 1 will be trained to become supervisors and train and support a cohort of new non-specialist facilitators for Group PM+ delivery in Phase 2. This model employs a train-the-trainers model to replicate routine service delivery especially in settings where mental health specialists may not be available to provide robust technical support and supervision to lay PM+ facilitators. The aim is to compare effectiveness and implementation outcomes of Group PM+ when delivered within routine care, to identify best practices for implementation, and ultimately, to shorten the time lag between intervention research and routine uptake.
