This study discusses the impact of the Enriched Home Environment Program (EHEP) on participation in home activities among two children with ASD using case study methodology. EHEP involves occupational therapists to collaborate with families of children with ASD to educate them about the impact of factors that influence child's participation within the home environment; and help them generate their own strategies to adapt or modify the environment, or routines to meet the needs of the child. The results of the study suggest that EHEP is effective in enhancing participation of children with ASD within their home environments.
