Titre : Callous-unemotional traits, cognitive functioning, and externalizing problems in a propensity-matched sample from the ABCD study Type de document : Texte imprimé et/ou numérique Auteurs : Samantha PERLSTEIN, Auteur ; Yael PAZ, Auteur ; Jakob SEIDLITZ, Auteur ; Adrian RAINE, Auteur ; Samuel HAWES, Auteur ; Amy BYRD, Auteur ; Rebecca WALLER, Auteur Article en page(s) : p.333-349 Langues : Anglais (eng) Mots-clés : callous-unemotional traits cognitive function aggressive behavior externalizing disorders Index. décimale : PER Périodiques Résumé : Background Many studies show that both callous-unemotional (CU) traits (e.g., low empathy, lack of guilt) and cognitive difficulties increase risk for externalizing psychopathology across development. However, other work suggests that some aggression (e.g., relational, proactive) may rely on intact cognitive function, which could vary based on the presence of CU traits. Moreover, no prior research has adequately accounted for common risk factors shared by CU traits, cognitive difficulties, and externalizing problems, which confounds conclusions that can be drawn about their purported relationships. The current study addressed these knowledge gaps by leveraging rigorous propensity matching methods to isolate associations between CU traits and different dimensions of cognitive function and externalizing problems. Methods Associations between CU traits, cognitive functioning, and externalizing outcomes were tested within dimensional (n?=?11,868) and propensity-matched group-based (n?=?1,224) models using data from the Adolescent Brain Cognitive Development Study?, with rigorous statistical control for shared sociodemographic risk factors. Cross-sectional outcomes were parent-reported symptoms of conduct disorder (CD), oppositional defiant disorder (ODD), and attention deficit hyperactivity disorder (ADHD). Longitudinal outcomes were child-reported overt and relational aggression. Results CU traits were uniquely related to more parent-reported CD, ODD, ADHD symptoms, as well as more child-reported aggressive behaviors. Effects of cognitive difficulties were domain specific and were not consistent across dimensional and propensity matched models. There was minimal evidence for divergent associations between CU traits and externalizing outcomes as a function of cognition (i.e., no moderation). Conclusions Rigorous control for sociodemographic factors within propensity-matched models establish CU traits as a robust and unique risk factor for externalizing psychopathology, over and above difficulties with cognitive functioning.

Preliminary evidence for the STAR model comes from work in early childhood. However, studies are needed that explore the STAR dimensions in late childhood and adolescence when severe conduct problems (CP) emerge. Moreover, it is unclear how variability across the full spectrum of threat sensitivity and affiliation gives rise to different forms of psychopathology beyond CU traits. Methods The current study addressed these gaps using parent- and child-reported data from three waves and a sub-study of the Adolescent Brain Cognitive Development Study? of 11,878 youth (48% female; ages 9?12). Results Consistent with the STAR model, low threat sensitivity and low affiliation were independently related to CU traits across informants and time. Moreover, there was significant interaction between the STAR dimensions, such that children with lower sensitivity to threat and lower affiliation had higher parent-reported CU traits. Unlike CU traits, children with higher threat sensitivity had higher parent-reported CP and anxiety. Finally, children with lower affiliation had higher parent-reported CP, anxiety, and depression. Results largely replicated across informants and time, and sensitivity analysis revealed similar findings in children with and without DSM-5 defined CP. Conclusions Results support the STAR model hypotheses as they pertain to CU traits and delineate threat sensitivity and affiliation as independent transdiagnostic risk factors for different types of psychopathology. Future research is needed to develop fuller and more reliable and valid measures of affiliation and threat sensitivity across multiple assessment modalities.

Titre : Genetic versus environmental influences on callous–unemotional traits in preadolescence: The role of parenting and parental psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Samantha PERLSTEIN, Auteur ; Samuel HAWES, Auteur ; Alexandra Y. VAZQUEZ, Auteur ; Ileana PACHECO-COLON, Auteur ; Sarah LEHMAN, Auteur ; Justin PARENT, Auteur ; Amy BYRD, Auteur ; Rebecca WALLER, Auteur Article en page(s) : p.1686-1701 Langues : Anglais (eng) Mots-clés : callous–unemotional traits environment etiology genetics parenting twin study Index. décimale : PER Périodiques Résumé : Children with callous “unemotional (CU) traits are at risk for severe conduct problems. While CU traits are moderately heritable, parenting also predicts risk. However, few studies have investigated whether parenting factors (e.g., acceptance, conflict, parental psychopathology) moderate the etiology of CU traits, while accounting for gene “environment correlations. To address this knowledge gap, we used data from 772 twin pairs from the Adolescent Brain and Cognitive Development Study to test bivariate models that explored overlapping etiological influences on CU traits and child reports of their parenting environment. We also used gene-by-environment interaction models to test whether parenting moderated genetic versus environmental influences. There were no overlapping etiological influences on CU traits and parental acceptance, but modest genetic and non-shared environmental overlap between CU traits and family conflict. Parental acceptance and psychopathology moderated non-shared environmental influences, with stronger non-shared environmental influences on CU traits among children who experienced lower parental acceptance and greater parental psychopathology. Family conflict only moderated environmental influences when models did not covary for conduct problems. Parental acceptance and parental psychopathology may be specific environmental protective and risk factors for CU traits, whereas family conflict may represent a general environmental risk factor for both CU traits and conduct problems.
