Research shows that Latinos are less likely to be diagnosed with autism than their non-Latino counterparts. One factor that may contribute to these differences is that autism diagnostic instruments have not been adapted for the Latino population. The present study compared scores from the Autism Diagnostic Interview-Revised for two groups: 48 Latino adolescents and adults with autism and a matched sample of 96 non-Latino Whites. There were no significant differences between the two groups in total impairments in social reciprocity or communication. However, lower levels of restrictive-and-repetitive behaviors were found among Latino adolescents and adults with autism compared to Whites. Findings suggest that there may be cultural equivalency in some domains, but others may warrant further exploration.
