Autism Screening Tools: An Evaluation of the Social Communication Questionnaire and the Developmental Behaviour Checklist-Autism Screening Algorithm
Witwer, Andrea N.; Lecavalier, Luc
Journal of Intellectual & Developmental Disability, v32 n3 p179-187 Sep 2007
Background: This study is the first to evaluate the "Social Communication Questionnaire" (SCQ) and the "Developmental Behaviour Checklist-Autism Screening Algorithm" (DBC-ASA) in the same sample of school-aged children with intellectual disability (ID) with and without Pervasive Developmental Disorders (PDDs). Method: Parents of 49 children (36 with PDDs and 13 with ID) completed a survey that included a demographic form, a measure of adaptive behaviour (the SIB-R), the SCQ, and the DBC-ASA. Results: According to established cut-offs, the SCQ's sensitivity was 0.92 and specificity was 0.62, and the DBC-ASA's sensitivity was 0.94 and specificity was 0.46. Six of the seven false positives on the DBC-ASA had DBC Total Problem Behaviour scores above the clinical cut-off. By contrast, all six true negatives had Total Problem Behaviour scores below the clinical cut-off. No such pattern was noted for the SCQ. Conclusion: While both instruments have good psychometric properties, the results of this study suggest that clinicians and researchers should exercise caution when utilising the DBC-ASA to screen for PDDs in individuals with significant behaviour problems, as this could decrease its diagnostic validity.
