Comparison of Autistic Traits between Iranian Students with Different Ethnical Background: A Cross-Cultural Study ​

Abstract

Background: Autistic traits (ATs) include symptoms associated with autism spectrum conditions (ASCs), which are assumed to be continuously distributed across the general population. Studies had indicated the cultural differences in the expression ATs. To our knowledge, this is the first study designed to compare the expression of autistic traits between different ethnicities from the same country. Methods: Using the Autism-spectrum Quotient (AQ-28), we examined the possible cultural differences in the expression of autistic traits from four groups of students with different ethnicities backgrounds, including Turkish (n = 262), Persian (n = 290), Kurdish (n = 300), and Luri (n = 307) students. Results: Behaviors associated with autistic traits were reported overall higher for males than females. Also, significant cultural differences in autistic traits were found that were different for males and females. Furthermore, while the medical sciences student group scored significantly than the humanities group in the Imagination dimension, the humanities group had significantly high scores in Number/Pattern dimensions than the engineering and medical sciences groups. Limitations: First, other ethnicities (e.g., Arabs, Baloch) were not studied because of the lack of access. Second, for data gathering, we used only the self-report method. Third, our study included only a student sample but not the community and clinical samples from different ethnicities. Finally, our study sample included only students who are not representative of their entire ethnicity.Conclusions: Altogether, our results provide further support for the idea that the expression of ATs is significantly influenced by culture.
