Background/Description
The Child Behavior Checklist for Ages 6-18 (CBCL/6-18) is a widely used tool designed to assess a wide range of behavioral and emotional problems in children and adolescents. Originally developed in 1983, the CBCL has undergone several revisions to enhance its reliability and validity. The CBCL is part of the Achenbach System of Empirically Based Assessment (ASEBA) and provides standardized data on a child’s behavioral and emotional functioning.
The CBCL/6-18 is intended for use by parents and caregivers to report on the child’s competencies and behavioral issues, facilitating early identification and intervention. It includes 120 items that measure specific domains of behavior and emotional problems, including anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, and aggressive behavior
Administration, Scoring and Interpretation
- Preparation: Ensure that the parent or caregiver has a quiet, comfortable environment to complete the checklist.
- Completion: The parent or caregiver rates each of the 113 items based on the child’s behavior over the past six months. Each item is rated on a three-point scale: 0 (not true), 1 (somewhat or sometimes true), and 2 (very true or often true).
- Scoring: The scores are summed and converted into standardized scores based on age and gender norms. The checklist yields scores for syndrome scales, internalizing and externalizing broad-band scales, and a total problems scale.
- Interpretation: Higher scores indicate greater behavioral and emotional difficulties. Scores are compared to normative data to determine clinical significance
Reliability and Validity
The CBCL/6-18 has demonstrated strong reliability and validity across diverse populations. Its psychometric properties include:
- Construct Validity: The CBCL has shown high convergent, discriminant, and factorial validity.
- Criterion Validity: It has demonstrated good predictive and postdictive validity.
- Reliability: The CBCL has high internal consistency and test-retest reliability.
- Sensitivity and Specificity: Sensitivity rate of 0.92 and specificity rate of 0.82
