Background: Youths with intellectual disabilities (ID) exhibit low levels of physical activity, but the underlying contributors to behavior are unclear. We compared physical activity enjoyment, perceived barriers, beliefs, and self-efficacy among adolescents with ID and typically developing (TD) adolescents.
Methods: A questionnaire was administered to 38 adolescents with ID (mean age, 16.8 years) and 60 TD adolescents (mean age, 15.3 years). Of the original 33 questionnaire items, 23 met the test-retest reliability criteria and were included in the group comparisons.
Results: Fewer adolescents with ID reported that they have someone with whom to do physical activity (64% vs 93%: P < .001), and a greater percentage of adolescents with ID perceived that physical activities were too hard to learn (41% vs 0%; P < .001). Fewer adolescents with ID believed that physical activity would be good for their health (92% vs 100%; P = .05). More adolescents with ID reported a dislike of individual physical activities (P = .02). A large percentage of adolescents with ID (84%) responded that they were good at doing physical activities, but the difference between groups was only of borderline significance (95% of TD adolescents, P = .06).
Conclusions: Adolescents shared many of the same perceptions about physical activity, but some important differences between groups were identified.
