Residual Scope: Web-based Physical Activity Intervention for Children with ALL

PRIMARY OBJECTIVES: I. To compare the effects of a rewards-and web-based physical activity intervention that includes structured social interaction between participants to the same web-based physical activity intervention that does not include rewards or structured social interaction on fitness among children and adolescents following treatment for acute lymphoblastic leukemia (ALL). SECONDARY OBJECTIVES: I. To evaluate the effect of a rewards-based, socially interactive web-based physical activity intervention on markers of cardiometabolic health among children and adolescents following treatment for ALL (compared to the same web-based physical activity intervention without rewards or social interaction). II. To evaluate the effect of a rewards-based, socially interactive, web-based physical activity intervention on physical activity, quality of life, fatigue, and school attendance among children and adolescents following treatment for ALL (compared to the same web-based physical activity intervention without rewards or social interaction). III. To determine if the effect of a rewards-based, socially interactive, web-based physical activity intervention on markers of cardiometabolic health is mediated by changes in fitness among children and adolescents following treatment for ALL (compared to the same web-based physical activity intervention without rewards or social interaction). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive educational handouts about physical activity and are encouraged to increase physical activity to at least 420 minutes per week. Patients wear Sqord activity monitor daily and upload data at least once a week to the Sqord website. Patients also access the limited version of Sqord website to get basic information related to their physical activity for 6 months. ARM II: Patients receive educational handouts about physical activity and are encouraged to increase physical activity to at least 420 minutes per week. Patients wear Sqord activity monitor daily and upload data at least once a week to the Sqord website. Patients also access the full version of the interactive-reward based Sqord website to see their activity, earn activity points, see other Sqord player's activity, and interact with other Sqord members for 6 months. After completion of study, patients are followed up at 24 and 48 weeks.
