Discriminant validity and clinical utility of the CBCL with anxiety-disordered youth.

This study investigated the utility of several scales of the Child Behavior Checklist (CBCL) when diagnosing anxiety disorders in youth. Participants were the mothers and fathers of 130 children (ages 7 to 14; M = 9.61 years, SD = 1.74; 69 boys, 61 girls) who were evaluated at a specialty mental health clinic (100 were referred for treatment; 30 were nonanxious volunteers). For both mothers' and fathers' reports, the highest correlations were found between the Anxious/Depressed subscale and the severity of generalized anxiety disorder (GAD); the second highest relations were between the Withdrawn subscale and the severity of social phobia (SP). Using either mothers' reports or fathers' reports, receiver operating characteristics (ROC) analyses identified cutoff scores that were useful in ruling in the presence of an anxiety disorder in general but did not identify cutoff scores to rule in the presence of principal GAD or principal SP. For mothers' reports only, receiver operating characteristics analyses identified a useful cutoff score to rule out the presence of an anxiety disorder, as well as a cutoff score to rule out the presence of principal GAD. Finally, discriminant function analyses determined the most useful subscales for ruling in and ruling out an anxiety disorder in general, as well as principal GAD and principal SP. Findings are discussed with regard to diagnosis of child anxiety and the clinical utility of the CBCL with anxious youth.
