Few studies have focused on home participation of high-functioning children with autism spectrum disorder. We employed a mixed-methods design to explore and compare parent perspectives on (1) participation of children with and without autism spectrum disorder in activities at home, (2) the environmental features and resources that affect these children's home participation and (3) the strategies parents use to help their children participate at home. The Participation and Environment Measure for Children and Youth (PEM-CY) was used to gather online survey and qualitative data from parents of 99 high-functioning children with autism spectrum disorder and 241 children without autism spectrum disorder. Independent sample t-tests and X[superscript 2] tests were used to explore differences between groups, and Cohen's d was calculated to examine effect sizes. Differences were obtained on all Participation and Environment Measure for Children and Youth dimensions but particularly when comparing parents' satisfaction and perceived environmental barriers to their children's participation. The qualitative analyses revealed that parents in both groups used similar strategies to facilitate their children's participation at home, although parents of children with autism spectrum disorder made use of more distinct modifications. Our results highlight the importance of environmental aspects and point to how practitioners can support families in their efforts to promote their child's participation at home.
