Study Arms (3)

Financial and social intervention

EXPERIMENTAL

Participants will receive the usual standard care (same as control group), loss-framed financial incentives, social incentives and weekly feedback on performance for 6 months.

Behavioral: Financial and social incentives

Control

NO INTERVENTION

Participants will receive standard care including patient screening and education on diet, physical activity, and smoking conducted by a multi-disciplinary team. Participants in the control group will neither be told their baseline step count nor receive any feedback messages.

Financial intervention

EXPERIMENTAL

Participants will receive the usual standard care (same as control group), loss-framed financial incentives, and weekly feedback on performance for 6 months.

Behavioral: Financial incentives

Interventions

Financial and social incentives BEHAVIORAL

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.
