Web-based interventions helping people with type 2 diabetes become regularly active: importance of online peer-support versus personalized delivery of content.

Inclusion criteria

Inclusion criteria: 1. The target population for this research project are Canadian men and women with type 2 diabetes 2. Patients not meeting the Canadian Diabetes Association guidelines related to aerobic PA 3. Being able to understand French 4. Being able to navigate on the Internet 5. Being between 18 and 65 years of age 6. Not having medical indications limiting the practice of PA Investigators will be able to judge if inclusion criteria are satisfied with a self-reported questionnaire administered to potential participants via the interventions’ websites, during the study registration process.

Design outcomes

Primary

Measure	Time frame
Physical activity levels will be evaluated from an adapted version of the Godin Leisure Time Exercise Questionnaire (GLTEQ). To explain, the measures will be self-reported via the intervention websites, where participants will indicate: 1. The frequency with which they practiced intensity-specific PA activities (i.e. low, moderate, vigorous) for a typical 7-day week (closed question) 2. The average duration, in minutes, of these activities for each intensity category. 3. Final PA levels will be obtained by calculating the converted total minutes per week of moderate intensity PA participants are practicing during a typical week, while only considering moderate (4 METS) to vigorous (7.5 METS) types of PA, and where the total minutes of vigorous PA/week will be considered as 1.875x minutes of moderate PA/week (7.5 METS/4 METS = 1.875). Using this method, a participant will be considered "regularly active" with a PA level that is equal to or greater than 150 minutes of moderate physical activity/week. This threshold corresponds to the recommendations of the Canadian Diabetes Association for aerobic physical activity.	—

Secondary

Measure	Time frame
Items related to intention, attitude, self-efficacy, social influence and type of motivation will be assessed. Data collected from these items will again be self-reported, as participants will provide their answers during baseline, 3-month follow-up, and 9-month follow-up assessments directly on the interventions’ Websites. Regarding the items related to intention, attitude, self-efficacy and social influence, these were validated during a previous study of Boudreau and Godin. The items were submitted to a test-retest procedure over a two-week period to a subgroup of 30 individuals with type 2 diabetes. The mean age of participants was 58.9 years (SD = 9.8), 33% were male and 33% had completed postsecondary education. Test-retest intraclass correlation coefficients and Cronbach's alpha coefficients were verified and are reported elsewhere. As for the items assessing the type of motivation of participants, a modified, validated, francophone version of the BREQ-2 [85] (Behavioral Regulation in Exercise Questionnaire, version 2) was used to measure all possible types of motivation a participant can hold, including integrated motivation, which is normally absent in the standard BREQ-2. Construct & discriminant validity was assessed with confirmatory factor analysis by the investigators who developed the questionnaire used for the present study.	—
