Insufficient physical activity (PA) is prevalent amongst adolescents, particularly those diagnosed with autism spectrum disorders. According to the World Health Organization (2020), globally, 81% of adolescents do not meet the recommended levels of PA. Whole-day interventions (i.e., interventions implemented throughout the day) can effectively increase PA levels holistically throughout the day, in line with PA guidelines. However, research remains scarce regarding the effectiveness of whole-day interventions (i.e., interventions implemented throughout the day) for increasing PA levels in individuals diagnosed with ASD. The present study evaluated the use of a multicomponent intervention package comprising progressive goal setting, self-monitoring, feedback, and reinforcement, implemented by the parent to increase whole-day step count in two adolescents diagnosed with ASD. The participants increased their daily step counts to 14,000 steps by the conclusion of the study, thus meeting or exceeding PA guidelines. Perceived social validity was high among both parent and participants, and behavioural outcomes point to high social validity among participants. The implications of the findings are discussed in this paper.
