Cultural dimensions of autism spectrum disorder (ASD) are relatively unexplored in the research literature. The current study is a systematic scoping review describing social, educational, and psychological research focused on individuals with ASD and their family members in Arab countries and cultures. Seventy studies met eligibility criteria. Most of the studies were from Jordan, Saudi Arabia, and Lebanon. Most of the identified research addressed three major domains: the prevalence of ASD and diagnosis issues, the experiences and outcomes for Arab caregivers of individuals with ASD, and social and communication behaviour of Arab individuals with ASD. There were significant gaps in research evidence base, including research on interventions and on ASD services. Overall, the included research was appraised as being of weak quality.
