The Child Behaviour Checklist (CBCL) is a widely used caregiver report form identifying problem behaviour in children. It is widely used in both research and clinical practice with youths. It has been translated into more than 90 languages, and normative data are available integrating information from multiple societies. Because a core set of the items have been included in every version of the CBCL since the 1980s, it provides a meter stick for measuring whether amounts of behaviour problems have changed over time or across societies. This is a helpful complement to other approaches for looking at rates of mental-health issues, as the definitions of disorders have changed repeatedly over the same time frame.
Like on the preschool version, the school-age version of the CBCL (CBCL/6-18) instructs a respondent who knows the child well (usually a parent or other close caregiver) to report on the child’s problems. Alternative measures are available for teachers (the Teacher’s Report Form) and the child (the Youth Self Report, for youths age 11 to 18 years). The school-age checklist contains 118 problem behaviour questions.
