Obesity Clinical Trial - Project Step: Evaluating Deposit Contracts &

Status Completed

Clinical Trial Summary

The purpose of this study is to test whether deposit contracts, wherein individuals invest their own money with the study to serve as the incentive, with or without daily feedback about progress help individuals to increase step counts and more often meet a step goal compared to self-monitoring only.

Clinical Trial Description

Approximately 68% of adults are overweight or obese, which is associated with increased risk for health conditions, including cardiovascular disease, type 2 diabetes, and cancer. These individuals are more often sedentary than the general population, which compounds the risk for these same conditions. While the benefits of engaging in physical activity are well-established, few individuals are able to successfully increase activity to recommended levels. Existing intervention programs, often derived from theories such as social cognitive theory or related theories, have had limited success. Behavioral economics offers a promising alternative, suggesting that engagement in any behavior is based on the maximizing utility and happiness. Interventions based on this theory aim to increase the immediate benefit of engaging in physical activity, often using a financial incentive.

This study will last for 16 weeks. Each participant will invest $42 with the study, and be exposed to to each of three interventions. All participants will have the use of a FitBit for ongoing self-monitoring and a step-count goal of 10,000 steps per day. In one condition, these will be the only interventions you receive. In one condition, you will receive a monetary consequence for meeting or not meeting the goal. Each day during the incentive conditions, you will be eligible to lose $0.75 of your own money for not meeting the goal, or to earn back $0.75 of your money plus $0.75 from the study (i.e., a total of $1.50) for meeting the goal. In the third condition, you will have daily feedback mid-afternoon about your distance from the goal and the money you stand to gain or lose. You will be made aware of what condition you are in. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
