Parental First Concerns and Timing of Autism Spectrum Disorder Diagnosis

Specific developmental concerns can distinguish between an early versus later diagnosis of autism spectrum disorder (ASD). Caregiver survey responses of children ae 9 years-of-age (2012) with ASD were used to evaluate developmental concerns and associations with age of diagnosis [early (< 3 years: n = 106) vs. later (ae 3 years: n = 432)] using logistic regression. Concerns arose at mean age 18 and 35-months for children diagnosed early versus later, respectively. Concerns about poor eye contact (aOR 1.81, CI 1.08, 3.05), pointing/gesturing (aOR 2.74, CI 1.60, 4.70), response to own name (aOR 3.03, CI 1.75, 5.23), and babbling/speaking (aOR 1.67, CI 0.98, 2.82) were associated with an early diagnosis. Caregivers and pediatricians are critical in early identification and timely entry into intervention.
