CAPE for measuring callous-unemotional traits in disadvantaged families: a cross-sectional validation study.

Callous-unemotional (CU) traits are important for designating a distinct subgroup of children and adolescents with behaviour problems.  As a result, CU traits are now used to form the specifier "with Limited Prosocial Emotions" that is part of the diagnostic criteria for the Conduct Disorder in the Diagnostic and Statistical Manual of Mental Disorders 5 Edition (DSM-5) and International Classification of Diseases 11 Revision (ICD-11).  Given this inclusion in major classification systems, it is important to develop and test methods for assessing these traits that can be used in clinical settings.
