Achenbach Child Behavior Checklist ages 6-18


The Child Behavior Checklist–Preschool and Child Behavior Checklist–School-Ageare part of the Achenbach System of Empirically Based Assessment (ASEBA) and use information collected from parents to assess the behavior and emotional and social functioning of children. The school-age forms assess children ages 6 to 17 years. Primary caregivers rate children on each item, indicating whether it is not true, somewhat or sometimes true, or very or often true, now or in the past six months. The internalizing group includes subscales that assess whether the child is emotionally reactive, anxious/depressive, withdrawn, or has somatic complaints. The externalizing group includes subscales that assess whether the child has attention problems or exhibits aggressive behavior. The school-age form provides information on 20 competencies covering children’s activities, social relations, and school performance through 113 items that describe specific behavioral and emotional problems. The items are also organized into six DSM-oriented scales based on factor analyses of parents’ ratings of 4,994 clinically referred children; the scales were normed on 1,753 children ages 6 to 18. The school-age normative sample represented the 48 contiguous states for socioeconomic status, ethnicity, region, and urban-suburban-rural residence. Both versions of the CBCL are widely used and have received an assessment rating of “A-Reliability and Validity Demonstrated” from the California Evidence-Based Clearinghouse for Child Welfare.
