Abstract
Examined the concurrent validity of the Problem and Intensity scales of the Eyberg Child Behavior Inventory (ECBI), using the Child Behavior Checklist (CBCL) as the criterion measure. Subjects were 159 children ages 4 to 16 referred for psychological evaluation between 1985 and 1988 for whom both the ECBI and CBCL had been completed. ECBI scales were correlated with both the Internalizing and Externalizing scales of the CBCL but were significantly more highly correlated with the Externalizing scale. Results supported the validity of the ECBI as a concise measure of childhood conduct-problem behaviors.
