Affective startle potentiation differentiates primary and secondary variants of juvenile psychopathy / Eva R. KIMONIS in Development and Psychopathology, 29-4 (October 2017)

KIMONIS, Auteur ; Kostas A. FANTI, Auteur ; Natalie GOULTER, Auteur ; Jason HALL, Auteur Article en page(s) : p.1149-1160 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Individuals with psychopathic traits show an attenuated emotional response to aversive stimuli. However, recent evidence suggests heterogeneity in emotional reactivity among individuals with psychopathic or callous–unemotional (CU) traits in the identification of primary and secondary subtypes, or variants. We hypothesized that primary CU variants will respond with blunted affect to negatively valenced stimuli, whereas individuals with a history of childhood maltreatment, fitting with theoretical conceptualizations of secondary psychopathy, will display heightened emotional reactivity. To test this hypothesis, we examined fear-potentiated startle between CU variants while viewing aversive, pleasant, and neutral scenes. Two hundred thirty-eight incarcerated adolescent (M age = 16.8 years, SD = 1.11 years) boys completed a picture-startle paradigm and self-report questionnaires assessing CU traits, aggressive behavior, and maltreatment. Latent profile analysis of CU trait, aggression, and maltreatment scores identified four classes: primary psychopathy variants (high CU traits, high aggression, low maltreatment; n = 46), secondary psychopathy variants (high CU traits, high aggression, high maltreatment; n = 42), and two nonpsychopathic groups differentiated on maltreatment experience (n = 148). Primary CU variants displayed reduced startle potentiation to aversive images relative to control, maltreated, and also secondary variants that exhibited greater startle modulation. Findings add to a rapidly growing body of literature supporting the possibility of multiple developmental pathways to psychopathic traits (i.e., equifinality), and extend it by finding support for divergent potential biomarkers between primary and secondary CU variants.

Developmental trajectories of conduct problems from childhood to adolescence: Early childhood antecedents and outcomes in adolescence / Olivier F. COLINS in Development and Psychopathology, 37-5 (December 2025)

Therefore, we tested if child- and environmental-level risk factors predict CP trajectory membership and if CP trajectories are associated with developmental outcomes in adolescence. Six waves of data (teacher-, parent- and child self-reports) were used from 2,045 children. General growth mixture modeling identified four CP trajectories (waves 2-5): childhood-persistent, childhood-limited, adolescent-onset, and low CP. Relative to the adolescent-onset CP trajectory, wave 1 child- and environmental-level risk factors increased the likelihood of being in the childhood-persistent CP trajectory, though all but two (callous-unemotional traits and non-intact family) antecedents lost significance after controlling for wave 1 conduct problems. Few significant differences emerged in risk factors when comparing childhood-persistent and childhood-limited CP trajectories. Individuals identified in the adolescent-onset and childhood-persistent CP trajectories faced a higher risk for later maladjustment than those in the childhood-limited CP trajectory, whereas the adolescent-onset and childhood-persistent CP trajectories only differed in three out of 13 outcomes. Overall, findings indicate that individuals with CP are at risk for later maladjustment, but predicting the childhood-persistent trajectory of CP in young children is difficult.

Facial reactions to emotional films in young children with conduct problems and varying levels of callous-unemotional traits / Eva R. KIMONIS in Journal of Child Psychology and Psychiatry, 64-3 (March 2023)

HAWES, Auteur ; Valsamma EAPEN, Auteur Article en page(s) : p.357-366 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Elevated levels of callous-unemotional (CU) traits have proven useful for identifying a distinct subgroup of children whose conduct problems (CP) are early emerging, severe, persistent, and underpinned by aberrant emotional processing. The early childhood emotional experiences and expressions of CP subtypes are poorly understood, despite their importance to understanding the problematic attachments and atypical social affiliation experienced by children with elevated CU traits. The current study aimed to test for differences in facial emotional reactions to mood-inducing film clips in children with CP and varying levels of CU traits. Method We compared facial emotional reactions during a developmentally appropriate mood induction task in a mixed-sex sample of clinic-referred preschool children (Mage=3.64 years, SD=0.63, 66.9% male) classified as CP with elevated levels of CU traits (CP + CU; n=25) versus low CU traits (CP-only; n=47), and typically developing children (TD; n=28). Results Relative to TD children, children with clinical CP showed less congruent and more incongruent facial emotional expressions to sad and happy film clips, controlling for child sex, age, and ethnicity. Conclusions Consistent with older samples, young children with CP show atypical facial emotional expressions in response to positive and negative emotional stimuli. Findings have implications for developmental models of childhood antisocial behavior and can inform the development of targeted interventions.

Factors differentiating callous-unemotional children with and without conduct problems / Tina D. WALL in Journal of Child Psychology and Psychiatry, 57-8 (August 2016)

This study investigated characteristics that might differentiate children with elevated CU traits with and without CP in an effort to identify factors that may reduce the risk for CP in children with limited prosocial emotions. Methods Utilizing a sample of 1,366 children from Cyprus, five groups were identified for further study based on latent profile analysis: low-risk (67.2%), high-CP/low-CU (7.9%), high-CU (9.4%), moderate-CP/CU (8.4%), and high-CP/CU (7.2%). The identified groups were compared on behavioral and social measures. Results There were significant main effects of group for: impulsivity and executive functioning; parenting; and connectedness to school. The high-CU group had significantly lower hyperactivity-impulsivity and executive functioning deficits, significantly higher self-regulation, and their mothers reported more maternal involvement and positive parenting than those in the high-CP/CU group. Also, the high-CU group showed more school connectedness than those in the high-CP/CU group. Conclusions These findings highlight several factors in the child and in his or her social environment that are associated with CU traits in the absence of serious CP and that may suggest targets for intervention for youth who may lack prosocial emotions.

The better of two evils? Evidence that children exhibiting continuous conduct problems high or low on callous–unemotional traits score on opposite directions on physiological and behavioral measures of fear / Kostas A. FANTI in Development and Psychopathology, 28-1 (February 2016)

FANTI, Auteur ; Georgia PANAYIOTOU, Auteur ; Chrysostomos LAZAROU, Auteur ; Raphaelia MICHAEL, Auteur ; Giorgos GEORGIOU, Auteur Article en page(s) : p.185-198 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The present study examines whether heterogeneous groups of children identified based on their longitudinal scores on conduct problems (CP) and callous–unemotional (CU) traits differ on physiological and behavioral measures of fear. Specifically, it aims to test the hypothesis that children with high/stable CP differentiated on CU traits score on opposite directions on a fear–fearless continuum. Seventy-three participants (M age = 11.21; 45.2% female) were selected from a sample of 1,200 children. Children and their parents completed a battery of questionnaires assessing fearfulness, sensitivity to punishment, and behavioral inhibition. Children also participated in an experiment assessing their startle reactivity to fearful mental imagery, a well-established index of defensive motivation. The pattern of results verifies the hypothesis that fearlessness, assessed with physiological and behavioral measures, is a core characteristic of children high on both CP and CU traits (i.e., receiving the DSM-5 specifier of limited prosocial emotions). To the contrary, children with high/stable CP and low CU traits demonstrated high responsiveness to fear, high behavioral inhibition, and high sensitivity to punishment. The study is in accord with the principle of equifinality, in that different developmental mechanisms (i.e., extremes of high and low fear) may have the same behavioral outcome manifested as phenotypic antisocial behavior.
