Enjoyment is a fundamental component of activity participation. This study compared leisure activity enjoyment experienced by typically developing children (TD; n = 64) and those with autism spectrum disorders (ASD; n = 67) from age 6 to 13. The TD children enjoyed "formal" and "physical" activities significantly more than the children with ASD. Symptom severity was negatively related to enjoyment of "overall", "formal", "physical" and "social activities". Older children with ASD enjoyed "overall", "informal", "recreational", and "self-improvement" activities significantly less than younger children, but no differences were seen across TD age groups. Children with ASD enjoyed swimming significantly more than TD children. Understanding patterns of activity enjoyment is useful for being better able to address a child's motivation to participate in various life activities.
