简要总结
The objective of this study is to examine whether a financial incentive program increases minutes of moderate-to-vigorous physical activity (MVPA) per week among cardiac rehabilitation (CR) graduates.
详细描述
A 52-week, randomized, crossover study design will be employed to examine the impact of financial incentives on MVPA among cardiac rehabilitation (CR) program graduates. Two experimental therapies, (1) online self-monitoring plus 'virtual rewards' (i.e. badges) (ExTrack.ca) and (2) online self-monitoring plus 'financial incentives' (ExTracker.ca), will be administered for six months, one after the other.
Study participants will be randomly assigned (1:1) to receive these therapies in one of two orders: Group A will receive ExTrack.ca (virtual rewards) for six months, followed by ExTracker.ca (financial incentives) for the next six months; Group B will receive the financial incentive condition first, and the virtual rewards condition second. While exposed to the incentive condition, participants will be eligible to earn financial reward per day exercise is tracked.
This study design allows for the assessment of 'real world' uptake of an incentive program among CR patients, since both Groups A and B will be able to earn incentives. This design will also help determine if incentives sustain MVPA in the first six months post-CR compared with the virtual rewards condition. Finally, the crossover design will allow the exploration of incentive 'timing' - that is, figuring out if incentives more effectively sustain MVPA post-CR if they are offered immediately, versus six months after graduation when patient motivation tends to wane.
In addition to tracking exercise sessions using the online self-monitoring tool, participants will be asked to record steps per day, and 10-minute MVPA bouts per day, using a StepsCount accelerometer. To check the accuracy of participant entries, participants will be asked to mail-in their accelerometers at the study mid- and end-points (26 and 52 weeks, respectively). Participants will also be asked to complete the Behavioural Regulation to Exercise Questionnaire (BREQ-3) at baseline (T1), study mid-point/crossover (T2), and study end-point (T3) as well as cardiopulmonary fitness assessments at T1 and T3.
