Abstract

The present study examined inter-rater agreement on the Anxiety Disorder Interview Schedule DSM-IV Child and Parent Interview (ADIS-IV-C/P) in youth with autism spectrum disorder and if age and ASD diagnosis moderated agreement. Diagnoses established for 70 7-16-year-old youth with ASD during a live administration of the ADIS-IV-C/P were compared to diagnoses identified by a second rater after listening to audiotaped recordings of the interviews. Inter-rater agreement on parent and child reports was excellent (k=1.00). Inter-rater agreement on principal diagnoses (k=0.91), individual anxiety diagnoses (k=0.85-0.97), and other comorbid diagnoses (i.e., major depressive disorder, dysthymia, oppositional defiant disorder, attention deficit hyperactivity disorder-Inattention/Hyperactivity/Combined Type) (0.89-1.00) were excellent; agreement did not differ as a function of ASD diagnosis or age. Results suggest that the anxiety disorders and comorbid disorders assessed by the ADIS-IV-C/P can be diagnosed by pairs of clinicians with good reliability.
