Behavioural Economics-based Incentives in Adults With Type 2 Diabetes (BET2)

Participants will be credited with HK$1,000 in their virtual accounts at the beginning of the trial. After baseline step counts are gathered in the second week, they will lose HK$40 for each subsequent week that they do not meet their personal weekly step target. Regarding social incentives, participants will be placed in teams of six, receiving feedback of their physical activity performance, rankings within their groups, and positive messages for encouragement. Nominated supporters will be informed of participants' performance for social support.
