2wT Training
The RCT study team, both researchers and implementation teams, was trained on 2wT through a 3-day hands-on 2wT study training session and an additional week of on-site support during the study launch at each site. For approximately 1 month, the 2wT system was reviewed daily by the central study team, providing brief feedback to the site teams via WhatsApp (Meta Platforms Inc) on areas for improvement. Throughout the RCT, the study team provided follow-up coaching and mentoring to the site teams via email, WhatsApp, and phone calls. The 2wT daily task sheets and quick guides provided reminders, whereas quarterly in-person refresher training ensured adherence to the 2wT study protocol. The study team provided additional support to the VMMC teams via weekly study calls, identifying problems and collaboratively resolving concerns with the 2wT system or VMMC program implementation. The study team visited the sites weekly for the first 3 months and monthly thereafter for quality improvement.
