Abstract
OBJECTIVE. The purpose of this study was to empirically derive dimensions of activity participation among a sample of school-age children with autism spectrum disorder (ASD; n = 713). Additionally, we examined the associations between dimensions of activity participation and child characteristics (i.e., chronological age, autism severity, gender) and family demographics (i.e., maternal education). METHOD. Exploratory factor analysis was used to determine the factors on the Home and Community Activities Scale (HCAS). Multiple regression was used to examine the extent to which child characteristics and family demographics were related to HCAS dimensions. RESULTS. A six-factor model best characterized activity participation among the school-age children with ASD, and child characteristics and family demographics were differentially associated with HCAS dimensions. CONCLUSION. The findings have implications for how activities may be categorized for children with ASD and suggest that the frequency of specific activities is affected by child characteristics and maternal education.
