CHIBE researchers apply concepts from the field of behavioral economics to design, implement, and evaluate interventions that improve health and build knowledge about efficacy, cost and effectiveness.
The Basic Science Core aims to support laboratory or low-cost field studies that will shed light on mechanisms that can generate behavior change. In contrast to previous large-scale field studies, which have often combined multiple mechanisms into one intervention in order to maximize impact on behavior, basic science projects supported by the Core focus on disentangling and precisely identifying the impacts of individual mechanisms.

Identifying effective strategies for treating obesity is both a clinical challenge and a public health priority. While a variety of approaches are successful in achieving initial weight loss, techniques for maintenance of initial weight loss have largely been unsuccessful. This randomized controlled trial will compare the relative effectiveness and cost-effectiveness of lottery-based incentives, traditional direct payments, and daily feedback without incentives among patients who successfully lost at least 5 kg over 6 months during participation in Weight Watchers (Pre Phase). Incentives will be provided to some study participants for the following 6 months (Phase I), and subjects will be followed for 6 more months to examine effects following cessation of incentives (Phase II).
