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:
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.
