Abstract

OBJECTIVE: Investigated the use of a combined scale (Worry/Depressed and Avoidant scales) from the Autism Spectrum Disorders-Comorbidity for Children (ASD-CC) as a measure of anxiety. Alternative methods of measuring anxiety were examined using the ASD-CC in an ASD population.

METHODS: Participants included 147 children, age 2-16 years, evincing a mixture of behavior problems. Comparisons between scores on the ASD-CC and Behavior Assessment System for Children, Second Edition (BASC-2) were examined to determine the most efficacious method of measuring anxiety and to establish convergent and discriminant validity.

RESULTS: The worry/depressed subscale was the most effective subscale of the ASD-CC to measure anxiety with proven incremental validity over the combined scale.

CONCLUSION: The worry/depressed subscale is the best measure of anxiety utilizing the ASD-CC in children with an ASD. Additionally, convergent and discriminant validity was demonstrated by comparing the scale with similar and dissimilar scales of the BASC-2.
