Cross-cultural differences in comorbid symptoms of children with autism spectrum disorders: An international examination between Israel, South Korea, the United Kingdom and the United States of America

Objective: To examine the relationship between culture and symptoms of comorbid psychopathology in those with autism spectrum disorders (ASD). Design: Multivariate analyses of variance (MANOVAs) for each country and each sub-scale of the Autism Spectrum Disorders-Comorbid for Children (ASD-CC). Follow-up independent univariate analyses and post-hoc tests as needed. Methods: Separate samples from South Korea, the UK and Israel were compared to a sample from the US in order to examine cultural contributions, using the ASD-CC. Results: Overall, few differences were found. Significantly, the US had significantly higher scores than South Korea on the avoidant sub-scale. Additionally, the US had significantly higher scores than Israel on the over-eating and tantrum sub-scales. No significant differences were found between the US and the UK. Conclusion: Cultural factors, such as views of typical behaviour, should be taken into account when examining symptoms of comorbidity in children with ASD.
