title: Targeted recruitment of adults with type 2 diabetes for a physical activity intervention.
abstract: Recruiting sufficient numbers of participants for physical activity trials for individuals with diabetes can be difficult because there are often many behavioral demands for participants, and inclusion and exclusion criteria can be extensive. This study examined the recruitment strategies used for a randomized, controlled trial designed to investigate the efficacy of an automated telephone intervention to promote physical activity in adults with type 2 diabetes in an urban Veterans Administration health care system. Traditional recruitment approaches of posting flyers and obtaining referrals from clinicians did not yield sufficient numbers of interested patients. Using the electronic medical record system to identify patients with uncontrolled diabetes allowed staff to send targeted mailings to participants, and 77% of participants were recruited using this method. The targeted mailing approach elicited a positive response rate of 12% (328 of 2,764 potential participants identified) and appeared to produce a more representative and appropriate sample than other recruitment methods used. Lessons learned in this study may be helpful to researchers in future trials who attempt to recruit participants with diabetes for physical activity protocols.
