New study shows minority toddlers with autism are more delayed than affected Caucasian peers
Date:2/21/2012

ildren were evaluated by their caregivers using the Communication and Symbolic Behavior Scales Developmental Caregiver Questionnaire (CSBS-DP CQ) and by research clinicians using the Mullen Scales of Early Learning and the Autism Diagnostic Observation Schedule-Generic (ADOS). After controlling for participants' socioeconomic status, all three tools indicated a significant difference between minority and non-minority children.

Previous studies published by Dr. Landa and her colleagues at Kennedy Krieger show that detection of ASD is possible at as early as 14 months of age. While early diagnosis is crucial for accessing intervention services, studies examining children from minority groups suggest considerable delays in the diagnosis of ASD in these children relative to their Caucasian peers.

Dr. Landa points to cultural differences in what communities perceive as typical and atypical development in young children, the relationships between families and respected community physicians, and the stigma that some cultures place on disability as areas where education and awareness could have meaningful impact.

"Addressing cultural influences gives us a clear target to improve service delivery to minority children, but these findings may also suggest biological and other culturally-related differences between Caucasian and minority children with autism," says Landa. "There are other complex diseases that present differently in different ethnic groups and more research is needed to investigate this possibility."

The findings of this research prompted Dr. Landa and her team to begin a study that will document the age at which minority parents first noticed signs of developmental disruption in their children, the specific nature of the behavior that concerned them, and the children's intervention history. Additional research is also needed to study group-specific differences in the presentation of autism symptoms between a variety of mi
