Center for Health Incentives and Behavioral Economics Research

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. 

Basic Science Core Request for Applications

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.  CHIBE researchers interested in applying for project support can click here for more information.

Developing Interactive Technologies to Improve Research and Health Behavior

Principal Investigators: Asch / Volpp

Co-investigators:  Bellamy, Halpern, Glanz, Goldberg, Groeneveld, Karlawish, Kimmel, Kuna, Loewenstein, Rozin, Shea, Troxel, Zauberman

David A. Asch, MD, MBA and Kevin G. Volpp, MD, PhD are developing IT infrastructure that will deploy clinical and behavioral research studies to advance the science at the intersection of behavioral economics and health.  The project is called Way to Health. For more information see:

Frailty Models for Quality of Life in Oncology (statistical methods)

Principal Investigator: Troxel

This project involves the development of new statistical models that facilitate the joint analysis of quality-of-life (QOL) data and clinical outcomes in oncology trials. A frailty models is a type of random-effects model for failure-time data that allows correlated events; estimation of this kind of model in the context of QOL allows for both the estimation of the correlation between length and quality of life and its adjustment when obtaining estimates of treatment or other intervention effects.

Deposit Contracts for Weight Loss

Principal Investigators: Volpp / Loewenstein 

Co-investigators:  Troxel

Deposit contracts are pre-commitment devices that are used in various non-health-related areas such as retirement savings investment, which help people overcome their present-biased tendencies. This is a randomized, controlled trial which tests the association between various types of deposit contract incentive schemes and weight loss among overweight volunteers in a workplace setting.

A Randomized Trial of Interventions to Improve Warfarin Adherence

Principal Investigators: Volpp / Kimmel 

Co-investigators:  Doshi, Loewenstein, Shea, Troxel

Pilot data from a study funded by the Aetna Foundation has shown that delivery of a lottery-based financial incentive was feasible and may be associated with substantial improvement in adherence. This larger phase III study is powered to evaluate the effectiveness and cost effectiveness of incentives and reminders for warfarin adherence.
