Callous-unemotional traits and reduced default mode network connectivity within a community sample of children / Rebecca H. UMBACH in Development and Psychopathology, 33-4 (October 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-4 (October 2021) . - p.1170-1183 Titre : Callous-unemotional traits and reduced default mode network connectivity within a community sample of children Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca H. UMBACH, Auteur ; Nim TOTTENHAM, Auteur Article en page(s) : p.1170-1183 Langues : Anglais (eng) Mots-clés : brain imaging developmental  callous-unemotional  resting state Index. décimale : PER Périodiques Résumé : Callous-unemotional (CU) traits characterize a subset of youth at risk for persistent and serious antisocial behavior. Differences in resting state connectivity in the default mode network (DMN) have been associated with CU traits in forensic and clinical samples of adolescents and with deficient interpersonal/affective traits (often operationalized as Factor 1 psychopathy traits) in adults. It is unclear whether these brain-behavior associations extend to community-based children. Using mixed model analyses, we tested the associations between CU traits and within-network resting-state connectivity of seven task-activated networks and the DMN using data from 9,636 9–11-year-olds in the Adolescent Brain Cognitive Development (ABCD) study. Even after accounting for comorbid externalizing problems, higher levels of CU traits were associated with reduced connectivity within the DMN. This finding is consistent with prior literature surrounding psychopathy and CU traits in clinically and forensically based populations, suggesting the correlation likely exists on a spectrum, can be detected in childhood, and is not restricted to children with significant antisocial behavior.
