Researchers wanted to find better ways to keep rural people who use drugs participating in long-term health studies. They tested whether asking participants to recruit a friend or family member as a 'study buddy' would help. The buddy was supposed to encourage the participant to attend follow-up appointments. This was compared against standard methods like appointment reminders from study staff.
The study included 739 adults from rural areas in Ohio, Oregon, and Kentucky who used opioids or injected drugs. About half were women, most were White, and many were unstably housed. Participants were randomly assigned to either try the study buddy approach or just receive standard reminders.
After 12 months, the study buddy method did not keep more people in the research than standard reminders. The numbers showed no meaningful difference. Only about one in four people in the buddy group actually recruited someone. Overall, keeping people in the study was challenging, with less than half still participating after a year.
This research shows that simply asking participants to find a buddy wasn't enough to solve the retention problem in this setting. The idea might need to be adjusted or combined with other supports. For now, standard reminder systems remain the tested approach for similar studies.
