Disparities in the Identification and Diagnosis of Autism Spectrum Disorder in Culturally and Linguistically Diverse Populations

Abstract

Early identification and intervention services play a critical role in determining the degree of communication development in children with autism spectrum disorder (ASD). However, researchers have reported that African-American and Hispanic populations are less likely to be diagnosed with ASD, often receive the initial diagnosis at later ages, and experience differences in access to services in comparison to other racial and ethnic groups. Studies have also documented lower participation rates of minorities in research studies of ASD. These differences have contributed to disparities in services for children with autism from culturally, linguistically, and economically diverse backgrounds. The purpose of this article is to discuss disparities in the identification and diagnosis of children with ASD from diverse backgrounds. It will discuss the clinical implications for speech-language pathologists (SLPs) in addressing potential barriers and strategies to facilitate services.
