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, Fitbit training, and 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.

尽管有许多好处，但患有自闭症谱系障碍和智力残疾的成年人通常不会进行健康水平的体育锻炼。我们进行了一项随机对照试验，以评估 Step It Up 计划的有效性和可行性，该计划使用支持的自我管理策略，对患有自闭症谱系障碍和智力残疾的成年人的每日步数、健康措施和感知生活质量进行评估。40 名 18 至 57 岁的参与者被随机分配到对照组或干预组。男性占参与者性别的 70.6%。两组都接受了 Fitbits、Fitbit 培训，并参与了前后评估。干预组参加了 Step It Up 计划。干预组的参与者步数明显更高，体重减轻更多。可行性和可接受性也很高。这项研究提供了有关使用支持的自我管理锻炼计划的宝贵数据，并深入了解其在家庭环境中的可行性。
