Contingency Management to Induce Exercise Among College Students

Abstract

Objective: The effects of contingency management to induce physical activity levels were examined in seven non-obese physically inactive undergraduate students by providing monetary payments using a multiple baseline, changing-criterion procedure. Methods: Participants attended a baseline phase, a subsequent intervention phase consisting of three exercise sessions per week for 4 weeks, and a follow-up session 2 weeks post intervention. A total of $145 was available for attendance and exercise contingency payments. Results: Results indicate that all participants significantly increased exercise during intervention from inactivity at baseline to exercising three 30-minute sessions per week. Participants maintained some gains during follow-up. Limitations: The study employed a small and homogenous sample size and required participants to exercise in a lab setting thus limiting external validity. Conclusions: These findings suggest that incentive-based interventions are an effective and viable means for inducing exercise.
