We examined the influence of three types of psychotherapy on general and specific aspects of psychopathology in adolescents with depression. General factor and specific conduct problems factor scores decrease across treatment and follow-up, whereas melancholic and depressive cognitions decrease only in the initial 6 weeks. Longitudinal courses of general and specific factors are similar across therapies, although conduct problems decrease more post-therapy after brief psychosocial intervention than CBT.

We examined whether scores on the CBCL Dysregulation Profile are meaningful indicators of clinical severity in children with disruptive behaviour. We found that the Dysregulation Profile identifies impaired, symptomatic children with disruptive behavior but situation & informant factors may influence the Dysregulation Profile and associated impairment.

This study identified profiles of reactive aggression, proactive aggression, callous-unemotional (CU) traits, and prosocial behavior in a sample of children with DB. Associations with social functioning (social interaction, social status) were then examined, along with sex differences in profile membership.

This study examined cross-informant evidence for a general factor of psychopathology (“P”) and a narrower, clinically oriented dysregulation general factor based on the Dysregulation Profile (“DP”) in a large clinical sample of children and adolescents. We also compared the magnitude of P and DP general factor associations with self-harm and suicidal ideation as an indicator of criterion validity.

This study examined the effects of comorbid ADHD symptoms, internalizing psychopathology, Callous–Unemotional (CU) Traits, and conduct problem severity on children’s response to an evidence-based psychosocial intervention. Children with DBD and comorbid symptoms appear to benefit from a multi-component intervention, but those with ADHD symptoms may require additional support to address social and behavioral challenges.
