Abstract: | The purpose of this study is to describe recruitment and retention experiences from three behavioral randomized controlled trials conducted among youth with type 1 diabetes. Eligibility, recruitment, and retention data were examined. Study-specific differential study participation and loss-to-follow-up analyses assessed the relations of patient characteristics with treatment completion and 6-month retention. Multivariable logistic regression identified factors independently associated with 6-month retention among all participants. Approximately 70–92 % of randomized participants completed treatment and 58–90 % were retained for follow-up. Older patients and non-Caucasian patients were less likely to enroll. Treatment completion and 6-month retention were less likely among youth who were older, had worse baseline glycemic control, lower household income, and/or unmarried parents. Some subgroups of patients are less likely to participate in research and are more susceptible to loss-to-follow-up. More work is needed to understand the facilitators and barriers to research participation. |
