Step It Up: Increasing Physical Activity for Adults With Autism Spectrum Disorder and Intellectual Disability Using Supported Self-Management and Fitbit Technology

Adults with autism spectrum disorder and intellectual disability often do not engage in healthy levels of physical activity despite its many benefits. We conducted a randomized control trial to evaluate the effectiveness and feasibility of the Step It Up program, which used supported self-management strategies, on daily step counts, health measures, and perceived quality of life for adults with autism spectrum disorder and intellectual disability. Forty participants, ages 18 to 57, were randomly assigned to a control or intervention group. Males accounted for 70.6% of participant gender. Both groups received Fitbits and Fitbit training, and they participated in pre- and post-assessments. The intervention group participated in the Step It Up program. Participants in the intervention group had significantly higher step counts and lost more weight. Feasibility and acceptability were also high. This study provides valuable data on using a supported self-managed exercise program as well as insight into its feasibility in home settings.
