Preliminary evidence suggesting caution in the use of psychiatric self-report measures with adolescents with high-functioning autism spectrum disorders

摘要

This study investigated the utility of self-report measures to screen for psychiatric comorbidities in autism spectrum disorders (ASDs). Thirty-eight 10–17 year olds with an ASD and without mental retardation completed: the Children’s Depression Inventory-Short version (CDI-S), Revised Children’s Manifest Anxiety Scale (RCMAS), Conners-Wells Adolescent Self-report Scale-Short edition (CASS-S), and Short Leyton Obsessional Inventory-Child Version (SLOI-CV). Their parents were interviewed with the Autism Comorbidity Interview-Present and Lifetime (ACI-PL) to establish psychiatric diagnoses. Sensitivity, specificity, positive and negative predictive values, and reliability coefficients were calculated for each self-report and compared to values from literature. The CDI-S and CASS-S yielded a high number of false negatives, with lower sensitivities and specificities in the sample than the literature. There was a nearly significant difference in total mean RCMAS scores between participants with and without anxiety, though again the means for both groups were below the threshold of concern. The SLOI-CV yielded a high false positive rate. All four instruments had reliability coefficients comparable to literature values. Results must be considered preliminary due to sample size. However, the findings suggest that although self-report instruments may provide useful information in the diagnosis of psychiatric comorbidities in ASD, caution must be exercised in their interpretation.
