Abstract
The purpose of this study was to learn about the diagnostic accuracy of Module 1 of the ADOS-G. Specifically, this study was designed to determine how well the ADOS-G differentiates children with autism from children with language impairments without autism. Data for this study were obtained from 10 children who were recruited from speech, language and hearing clinics in the metropolitan area of Baton Rouge, Louisiana. Visual inspection and statistical analyses indicated that the means of the ADOS-G scores for all domains (Communication, Social Interaction, and Communication + Social Interaction Score) were higher for the autism group than for the non-autism group. The ADOS-G also yielded high sensitivity but low specificity values for correctly classifying the participants’ clinical diagnoses. Visual inspection of individual items revealed that for four items in the Communication domain and three items in the Social Interaction domain, 50% or more of the participants with and without autism earned similar scores. Overall, this study suggests that the ADOS-G is able to differentiate between groups of children with autism and children with language impairment without autism; however, at the level of the individual, it has a tendency to over classify children as presenting with autism or ASD.
