Background: Automated, Internet-mediated behavior-change interventions can be disseminated widely and at a low per-person cost. They also allow users to receive support at a time and place that is convenient for them. However, some of these programs suffer from high rates of attrition. Online communities that allow participants to communicate with each other by posting and reading messages may decrease participant attrition. Methods: A randomized controlled trial of sedentary but ambulatory adult patients from an academic health system who use email regularly, and with at least one of the following: overweight (BMI ≥ 25), type 2 diabetes and/or coronary artery disease. All participants (n=324) wore enhanced pedometers for 16 weeks, uploaded step-count data and logged into the study website to view personalized feedback and goals. Those randomized to the “with online community” (WOC) group were able to post messages and read messages from other participants while those randomized to the “no online community group” (NOC) could not access this feature. Results: Participants increased their average daily steps by 1888 steps/day (Intention to treat: paired t-test, sem 133, p<.001), and there was no significant difference between groups. However, the percentage of completers was 13% higher in the WOC group than the NOC group (NOC: 66%, WOC: 79%, logistic regression, or = 0.49, p=.019). Conclusion: Online communities may be useful for solving the attrition problem in Internet-mediated health behavior change interventions.
