The relationship between callous-unemotional traits and internalizing psychopathology in adolescent psychiatric inpatients: a network analysis.

Background: Numerous studies have investigated the relevance of callous-unemotional traits in relation to externalizing psychopathology among children and adolescents. However, less research has examined the connections between callous-unemotional traits and internalizing psychopathology and findings were inconsistent. Consequently, the present study aimed to elucidate the role of callous-unemotional traits in the context of depression and anxiety while controlling for conduct problems, age, and gender.

Methods: The study utilized self-report questionnaire data from 978 adolescent psychiatric inpatients (M_age = 15.18, SD = 1.44) presenting a range of psychopathological conditions. A network analysis was conducted, incorporating callous-unemotional traits, depressive symptoms, anxiety symptoms, conduct problems, and covariates (age, gender). Additionally, comparisons were made between the networks of inpatients diagnosed with conduct disorders and those with internalizing disorders.

Results: The findings indicated that callous-unemotional traits were relevant within the general network, as well as in both the conduct disorder and internalizing networks. In both contexts, callous-unemotional traits were predominately positively associated with depression and conduct problems. Within the conduct disorder network, callous-unemotional traits exhibited primarily negative associations with anxiety, whereas the relationships within the internalizing network were more varied.

Conclusions: Our findings suggest that callous-unemotional traits hold substantial relevance for internalizing symptoms, supporting the notion that these traits should be considered potentially transdiagnostic factors.
