Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention involves providing relatively small, intermittent incentives in the form of points exchangeable for gift vouchers, offered over a 4-month period, to participants who successfully increase their physical activity or decrease their sitting time. Participants will be awarded one point per minute (capped at 30 points/day) of physical activity, and one point per minute (capped at 30 points/day) reduction of sitting time. Weight reduction is NOT a points incentive in this study but rather will be monitored as an outcome. Incentives are supplemented with a one-on-one motivational interview with a member of the research staff, for around 20 minutes duration, focused on goal-setting and addressing barriers at intervention commencement; and weekly SMS text messages providing encouragement/support. Participants also receive a Fitbit One device and Bluetooth weighing scales.

Efficacy
Statistical methods / analysis
Based on our previous physical activity studies, a sample of 80 adults was calculated to provide 80% power at a=0.05 to detect an effect size in the primary outcome, physical activity duration, of at least 0.3 (equivalent to 60 minutes of physical activity/week, an increase that is feasible but significant in this initially sedentary sample), allowing for up to 10% attrition over the 4-month study period. Study effects will be evaluated using t-tests and regression models predicting change in key outcomes from pre- to post-test.
