OBJECTIVE: To examine the effects of a tailored, print-based intervention for promoting physical activity among patients with type 2 diabetes. METHOD: This randomized controlled trial was conducted 2006 to 2007 in Tallahassee, FL. Patients diagnosed with type 2 diabetes (N = 85; mean age 57.1 years; 74.1% caucasian) were recruited from a community diabetes clinic. The four-week intervention was tailored to participants' current activity levels, motivational readiness, self-efficacy, and other relevant psychosocial constructs. Primary outcomes included self-reported physical activity and physical activity stage of change. RESULTS: Compared with usual care, participants receiving the intervention were more likely to progress in their physical activity stage of change between baseline and month one (OR 3.2, 95% CI 1.0 to 10.3) and were more likely to be in the Action or Maintenance stages at month one (OR 5.6, 95% CI 1.7 to 18.3). The change in weekly activity among intervention participants was 22 min greater than those receiving usual care, although this represented a non-significant difference, p = 0.22. CONCLUSION: While this print-based intervention has the potential to reach a large audience and produced improvements in relevant psychosocial constructs, more intensive programs may be needed to achieve greater behavioral improvements.
