Obesity has become a leading cause of health problems in the United States, creating a great need for interventions to increase physical activity. In this experiment, a package intervention consisting of task clarification, goal setting, self-monitoring, and feedback was evaluated across 4 participants in a multiple baseline design with a brief reversal for 2 of the 4 participants. Minor changes were made to the goal setting component for 2 participants in an attempt to increase calorie expenditure further. A fifth participant received task clarification, goal setting, and self-monitoring, which were evaluated in an ABAB reversal design. The level of increase was somewhat variable, but the intervention package was successful at increasing calorie expenditure in all 5 participants. Additionally, all participants reported that the research was beneficial and their physical activity level increased as a result of participating in the study.
