Exploring the clinical utility of the DSM-5 conduct disorder specifier of 'with limited prosocial emotions' in an adolescent inpatient sample

Abstract

Background: With the recent addition of a callous-unemotional (CU) specifier to the diagnosis of conduct disorder (CD) in the DSM-5, studies are needed to evaluate the clinical utility of this specifier and the best ways to identify youth meeting criteria for this specifier in clinical samples.

Methods: To this end, the current study examined cross-sectional correlates and treatment response across four groups of inpatient adolescents (N=382, ages 12-17): those with CD without the specifier, with CD and the CU specifier, CU alone, and a group of psychiatric controls. We used two different measures to identify adolescents with high levels of CU traits: the Antisocial Process Screening Device (APSD) [1] and the Inventory of Callous-Unemotional Traits (ICU) [2]. Questionnaires and structured interviews were used to evaluate a range of outcomes including presence of baseline levels and treatment outcomes of both externalizing and internalizing problems.

Findings: Results indicated that the ICU, but not the APSD differentiated between conduct disordered youth with and without the specifier on externalizing behaviors in both cross-sectional relations and treatment response.

Conclusions: The results of the current study caution the use of the most frequently used measure to identify the CU specifier, and make suggestions about alternatives.
