简要总结
This study proposes a novel behavioral intervention to help smokers in Thailand to achieve their goals of quitting. Smoking treatment programs are rare throughout most of Asia and unlikely to meet the impending demand for quitting that tobacco control regulations is stimulating. New approaches are needed.
The present study is a randomized controlled trial to test the effectiveness of a novel, scalable approach to smoking cessation that is targeted toward rural Southeast Asian communities. Thailand is used as a test case to explore if pairs of smokers quit successfully after making financially-backed commitments and receiving cash incentives to quit. The control group receives education and counseling about quitting. In addition to education and counseling about quitting, the intervention includes two key components:
- Each participant is encouraged to deposit his "cigarette money" on a weekly basis, to be returned only if the smoker quits successfully within three months. Such commitment contracts, based on theory from behavioral economics, are designed to help a person to maintain self-control and motivation in the face of temptation.
- Each participant is paired with another study participant. If both quit, each receives a cash bonus. The joint incentives are designed to lead partners to support each other throughout the quit attempt.
Thus, group commitment contracts marshal a robust blend of elements: financial commitment, social support, peer pressure, and monetary rewards. A larger, follow-up evaluation will clarify the relative importance of each of these elements.

Group commitment contracts
In addition to education and counseling, the intervention includes the following components:
- Each participant is encouraged to deposit his "cigarette money" on a weekly basis, to be returned only if the smoker quits successfully within three months.
- The project gives a series of two matching contributions of 150 baht each to participants who meet certain deposit requirements.
- Each participant is paired with another study participant. If both quit, each receives a cash bonus of 1,200 baht. At enrollment, pairs receive brief counseling on ways to support each other during the quit attempt.
干预措施: Group commitment contract (Behavioral)
