Hierarchical confirmatory factor analysis of the Child Behavior Checklist/4–18.

Hierarchical confirmatory factor analysis was used to evaluate the 2-factor 2nd-order structure of T. M. Achenbach's ( 1991 ) Child Behavior Checklist in a sample of 577 children who had been identified as having serious emotional disturbance. An alternative 1-factor 2nd-order model also was tested. Results supported T. M. Achenbach's model in which the broadband Internalizing factor was represented by the narrowband Withdrawn, Somatic, and Anxious/Depressed syndromes, and the broadband Externalizing factor was represented by the narrowband Delinquent and Aggressive syndromes. Consistent with T. M. Achenbach's model, the remaining narrowband syndromes (i.e., Social, Thought, Attention ) loaded equally on both broadband factors and should not be included in scoring either Internalizing or Externalizing. Fit of the 1-factor model also was good and only slightly poorer than the 2-factor model. Therefore, an overall score would be appropriate as a measure of global problem behavior.
