SUMMARY OF PHASE 3 In Phase 3 of the study, focus groups discussion will identify implementation challenges and areas for improvement in preparation for a R01 submission for an intervention at scale. There will be three types of focus groups: (1) MSM and TGW clients from the intervention group and (2) testing staff and administrators. Focus groups will separately be run for MSM (n=3) and TGW (n=1) clients to broadly assess their experience participating in the intervention and for testing staff (n=1) to examine perception of study procedures, and identify areas for improvement. All of the groups will discuss how to best adapt the study for future scale up and implementation. Specially, the client focus groups will cover barriers and facilitators to obtaining HIV prevention information through the intervention messaging and ask about how information receipt did (or did not) translate into healthy behavior change. Ultimately these findings will guide the scale up and implementation of a large scale R01 RCT.
