Barriers to an Information Effect on Diagnostic Disparities of Autism Spectrum Disorder in Young Children.

Objectives: Autism spectrum disorder (ASD) is underdiagnosed in children from minority and low socioeconomic status families, and reports indicate that parental "lack of awareness" of symptoms is a factor, which implicates the adoption of the category globally. However, parental knowledge of ASD has failed to explain emerging clusters of cases. The objective of the present research was to identify and describe barriers to an "information effect" in diagnosis.

Parental Action and Referral Patterns in Spatial Clusters of Childhood Autism Spectrum Disorder.

Sociodemographic factors have long been associated with disparities in autism spectrum disorder (ASD) diagnosis. Studies that identified spatial clustering of cases have suggested the importance of information about ASD moving through social networks of parents. Yet there is no direct evidence of this mechanism.

In the U.S., children with autism spectrum disorder (ASD) have been found to live in spatial clusters.
