Many people in the United States do not engage in the recommended levels of physical activity. Self-management strategies, including self-monitoring and goal setting, are among the interventions that have been used to increase physical activity in adults. Visual feedback has also been incorporated into interventions to increase physical activity. Minimal research has focused on increasing swimming behavior. The current study investigated the effectiveness of self-management strategies to increase swimming activity in adults. An automated recording device (watch) was used to collect data on participants’ swimming behavior. The effect of self-monitoring in the form of a self-graphing intervention to increase swimming activity was evaluated. If self-graphing alone was not effective, goal setting was added to the intervention. Three participants showed an increase in swimming activity when self-graphing was implemented. Two participants showed little or no change in activity across all phases. This study did not include any reinforcement contingencies for engaging in an increase in swimming activity. Future research directions are discussed.
