Achieved 90% Survey Completion Over 30 Days
University of New Mexico
Researchers at the University of New Mexico needed to run a complex longitudinal study over 30 days and maintain participant engagement. They faced the challenge of executing repeated surveys across the full study period. They needed a way to keep participants involved throughout the longitudinal timeline. The research team used a platform to recruit participants and manage participation across repeated surveys. They implemented a setup that supported sending and administering surveys multiple times over the 30-day period. They relied on the platform to help coordinate ongoing participation across the study. The study achieved a 90% survey completion rate across the full 30-day period. Participant engagement was maintained through the end of the longitudinal study. The research effort successfully collected repeated survey responses over the entire 30-day timeline.
