Do Parental Interviews for ASD Converge with Clinical Diagnoses? An Empirical Comparison of the 3di and the DISCO in Children with ASD, a Clinically-Referred Group, and Typically Developing Children

Two semi-structured parental interviews are available with algorithms developed to measure DSM-5 criteria of ASD, namely the Developmental, Dimensional and Diagnostic Interview (3di) and the Diagnostic Interview for Social and Communication Disorders (DISCO-11). The main aim of this study was to examine the agreement between classification according to both interviews, and their convergence with the clinical diagnosis. Therefore, the 3di and DISCO-11 were administered from three groups of parents of a 4-18 year old. Results showed 75% agreement between both instruments, but in the ASD group only 16% of the children scored above threshold on both instruments. Exploratory analyses suggested that the 3di failed to detect rigid and repetitive behaviors, whereas the DISCO-11 was insufficiently sensitive in detecting socio-communicative problems.
