Technology-based contingency management for walking to prevent prolonged periods of workday sitting.

Sedentary behavior is an emerging public health issue. Frequent, brief bouts of walking are recommended by experts to reduce the health risks correlated with physical inactivity and prolonged sedentary periods. The purpose of the current study was to extend the literature by evaluating a remote, technology-based contingency management (CM) intervention that reinforced frequent, brief bouts of walking to decrease prolonged periods of sitting during the workday. A packaged intervention consisting of a contingency contract, monetary incentives, goal setting, textual prompts, and performance feedback was implemented with individuals with sedentary job responsibilities working from home during the COVID-19 pandemic. The intervention increased the number of physically active intervals to mastery for 4 participants, thereby disrupting prolonged periods of sedentary time. For 2 participants, the intervention did not meaningfully increase the number of physically active intervals. Results suggest that a remote, digital CM intervention can decrease sedentary behavior in home office environments.
