Study Details

Study Description

Brief Summary

This study will evaluate the main effects of daily vs. weekly feedback and contingent vs. non-contingent incentives for increasing walking behavior among overweight and obese adults.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: Non-contingent incentives
  • Behavioral: Contingent incentives
  • Behavioral: Weekly feedback
  • Behavioral: Daily feedback
N/A

Detailed 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 (i.e., weighing the cost and benefit of the behavior). 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 8 weeks. All participants will have the use of a FitBit for ongoing self-monitoring and a personalized step-count goal designed to help increase daily steps. Participants will receive feedback on reaching their goals either daily or weekly.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Non-contingent incentives and weekly feedback

Participants will receive payment for participating in the study (regardless of goal attainment) and will receive weekly updates about their performance.

Behavioral: Non-contingent incentives
Incentives are provided for participation

Behavioral: Weekly feedback
Text message feedback is delivered weekly summarizing the past week's progress

Experimental: Non-contingent incentives and daily feedback

Participants will receive payment for participating in the study (regardless of goal attainment) and will receive daily updates about their performance.

Behavioral: Non-contingent incentives
Incentives are provided for participation

Behavioral: Daily feedback
Text message feedback is delivered daily summarizing the current day's progress

Experimental: Contingent incentives and weekly feedback

Participants will receive payment for meeting their daily goals and will receive weekly updates about their performance.

Behavioral: Contingent incentives
Incentives are provided for attaining daily goals

Behavioral: Weekly feedback
Text message feedback is delivered weekly summarizing the past week's progress
