Four databases were searched to identify studies published by Arab researchers on parents' perceptions of autism spectrum disorder and studies conducted by US researchers and published in systematic reviews of this topic. The electronic search resulted in 14 studies published by Arab researchers and 55 studies published by US researchers. The results showed that autism spectrum disorder has many of the same effects on Arab and American families. Six major areas were identified in the results. Financial difficulties associated with raising children with autism spectrum disorder were mentioned more in Arab studies than in US studies. Arab studies had more emphasis on gender than US studies. The results related to quality of life of parents of children with autism spectrum disorder in Arab studies were equivocal. US studies included comparisons with families without a child with autism spectrum disorder, and addressed factors that were associated with quality of life indicators. More health, educational, and social services were available in United States than in Arab countries, but some frustration was reported by US parents in obtaining appropriate services in some studies. A higher percentage of Arab studies mentioned the role of religious faith than US studies. Finally, social stigma was evidenced in both cultures, but not much research was available.
