内容摘要:Physical activity is very important for human life quality. How to make people to workout and form a habit is a long time challenge in health and behavioral studies. In this study, we design and run a field experiment on ex post feedback mechanism to induce people to work out. We design feedback message in two by two dimensions. On one dimension, we vary the feedback message by whether attributing the results to participants efforts or not (effort attribution treatment), and on the other dimension, we use “ I message” or “You message” to test whether the deictic relational framing of feedback matters (framing treatment).By using an exercising recording (i.e., “Dong Qi Lai”) applet embedded in WeChat, we conducted an 8-week field experiment in China. We find that: In the short run when feedback is provided (the first 5 weeks), on average, participants in“I message”treatment(i.e., We are so happy…) and“You message + effort”treatment(i.e., You make us so happy…) groups achieve the weekly exercise goals one more time than participants in control group. But in the long run when feedback is no longer provided (the later 3 weeks after intervention), theinfluences of “I message” and “You message + effort” cannot last in the long-term. What is more, the influences of “You message + effort” reverse and turn to negative in the long run. We also find that the effect of feedback is stronger among participants whose subjective ability of self-control and intrinsic motivation for workout are low.
