Obesity has become a leading cause of health problems in America, many of which can be combated by increasing physical activity. As a result, interventions targeting increased physical activity are greatly needed. In this study, a package intervention consisting of goal setting, self-monitoring, and feedback was evaluated across five participants in a multiple baseline design with a brief reversal for three of the five participants. The intervention package increased calorie expenditure for all five participants. Copyright © 2009 John Wiley & Sons, Ltd.
