Exploring Moderation Dynamics: Callous-Unemotional Traits, Parental Practices and Conduct Problems in JuvenileDelinquency.

Callous-unemotional (CU) traits, parental practices and conduct problems (CP) have been consistently identified across numerous studies as significant predictors of the severity and persistence of juvenile delinquency. This study seeks to investigate the moderation dynamics underlying the relationships between these variables among Arab incarcerated youth. Specifically, the study aims to (1) explore whether parental practices moderate the relationship between CU traits and CP among incarcerated youth in Jordan and (2) examine the bidirectional moderating influence of CU traits in shaping the dynamic relationship between parental practices and CP within the context of Arab juvenile delinquency. An observational survey design was employed, gathering data from 184 incarcerated youth across 11 rehabilitation centres in Jordan. Latent profile analysis identified three parental practice classes: more positive, balanced and more negative. Moderation analyses indicated significant associations between CU traits, parental practices and CP. Parental practices, especially positive ones, moderated the relationship between CU traits and CP, highlighting the protective influence of balanced parenting. Furthermore, bidirectional moderation effects were observed: CU traits moderated the link between parental practices and CP, while CP influenced parenting practices, particularly in the presence of elevated CU traits. The findings of this study underscore the vital role mental health nurses can play in addressing the behavioural and psychological challenges faced by youth involved in the justice system and their families. Specifically, mental health nurses can aid in ameliorating mental distress by supporting parents in understanding and managing CU traits and CP. Nurses can provide targeted educational programmes that empower parents with strategies to reinforce positive parenting practices and reduce negative interactions. Furthermore, nurses can facilitate access to community resources and therapy options, helping families build a supportive environment conducive to the mental well-being of the youth. These interventions are crucial not only for the direct treatment of juveniles but also in providing holistic support to their families, thereby enhancing the overall efficacy of mental health care in juvenile delinquency. This study highlights the essential role that mental health nurses play in managing behavioural issues among youth, emphasising the significance of implementing culturally sensitive interventions. Mental health nurses possess a pivotal position in early detection and intervention, which enables them to guide families in fostering positive parenting practices, essential for preventing delinquent behaviours. Their efforts to promote understanding and responsiveness within family dynamics make a significant contribution to the mental well-being of individuals, highlighting the necessity of their role in global mental health.

Callous-unemotional traits moderate the association between inhibitory control and disruptive behavior problems.

The presence of callous-unemotional (CU) traits may not be unique to conduct disorder (CD) but also extend to oppositional defiant disorder (ODD). While a distinct neurocognitive profile characterizes CU traits, it remains unclear whether this CU-related neurocognitive profile differs between youth with CD and ODD. This study investigated whether CU traits moderate the relationship between inhibitory control and CD or ODD symptoms. We leveraged computational modeling to decompose task-based inhibitory control in a sample of 200 children (59.5% boys, 86.5% Caucasian), aged 8 to 15 years (M = 10.10, SD = 1.88), referred to an outpatient child diagnostic clinic focused on externalizing problems. Analyses examined whether CU traits moderated the relationship between inhibitory control and CD or ODD symptoms while controlling for ADHD symptoms and child demographics. The results indicated that the strength of the relationship between inhibitory control and CD and ODD symptoms varies as a function of CU traits. Specifically, CD was linked to a more cautious decision-making style when elevated CU traits were present, whereas ODD was associated with more efficient decision making. These findings suggest distinct neurocognitive profiles based on CU traits, which vary between CD and ODD. Clinically, this underscores the importance of tailoring interventions for CD-CU and ODD-CU, focusing on decision making processes rather than merely addressing impulsivity. This research contributes to a more nuanced understanding of the interaction between neurocognitive processes and disruptive behavior, with significant implications for both theoretical models and treatment approaches.

Impact of an 8-Week, Intensive Summer Treatment Program on Improving Coercive Caregiver-Child Interactions Among Children With and Without Callous Unemotional Traits

The coercive process is the primary explanatory mechanism implicated in the maintenance of disruptive behavior disorders (DBDs), and understanding the coercive cycle may be especially important for caregivers with children with elevated callous-unemotional (CU) traits. The purpose of the current pilot study is twofold. First, we assessed whether the Summer Treatment Program (STP), an established intensive behavioral intervention for children with DBDs, reduced coercive caregiver-child interactions using a novel parent-report measure of coercive interactions. We then sought to assess whether the STP improved coercive caregiver-child interactions among children with elevated CU traits (i.e., moderated the effect). Thirty-three caregivers and their children who had been diagnosed with DBDs participated in the STP, which involved the children receiving behavior modification for 9 hours per day and caregivers attending a weekly behavioral parent training group session over the course of 8 weeks. Children (Mage = 8.51 years old, SD = 1.70, range 6–12) were primarily male (78.5%) and Hispanic/Latine (84.8%). A linear multilevel model revealed a statistically significant improvement in caregiver-child coercive interactions from pre- to posttreatment. However, child pretreatment CU traits moderated this effect such that families with children with elevated CU traits did not show improvement in caregiver-child coercive cycles following treatment. Results suggest the benefits of intensive behavioral treatment on the caregiver-child coercive cycle for many families, but the need to modify the intensity or dose of treatments for those with children with DBDs and elevated CU traits.

Parasympathetic Nervous System Functioning Moderates the Associations between Callous-Unemotional Traits and Emotion Understanding Difficulties in Late Childhood.

Callous-unemotional (CU) traits are characterized by low empathy, guilt, and prosociality, putting children at risk for lifespan antisocial behavior. Elevated CU traits have been linked separately to difficulties with emotion understanding (i.e., identifying emotional states of others) and disrupted parasympathetic nervous system (PNS) functioning. However, no study has investigated how PNS functioning and emotion understanding are jointly related to CU traits. We explored associations between CU traits, emotion understanding, and PNS functioning (indexed via respiratory sinus arrhythmia [RSA]) among children aged 7-10 years old (n = 55). We also tested whether deficits in emotion understanding differ across specific emotions (i.e., fear, pain, happiness, anger). Each child's RSA was continuously recorded while they watched a film that included emotionally evocative social interactions. To assess emotion understanding, children identified emotions replayed in 1s animations of scenes from the film. Parents reported on child CU traits, conduct problems, and demographic information. Higher CU traits were related to lower emotion understanding (β = -0.43, p = 0.03). PNS activity during the film moderated this association (β = -0.47, p < 0.001), such that CU traits were associated with lower emotion understanding among children with mean (B = -0.01, t = -2.46, p = 0.02) or high (i.e., 1 SD > M; B = -0.02, t = -3.00, p < 0.001) RSA levels during the film, but not among children with low RSA levels (i.e., 1 SD < M; B = 0.00, t = -0.53, p = 0.60). Moreover, we found that the observed moderated associations are driven by deficits in fear, specifically. The link between poorer emotion understanding, fear understanding in particular, and CU traits was attenuated for children who demonstrated patterns of PNS functioning consistent with attentional engagement while viewing the emotion stimuli.

Moderators of the relationship between callous-unemotional traits and externalizing problems in youth.

The names appear correctly in this record.] Callous-unemotional (CU) traits (i.e., tendencies to experience low levels of guilt and empathy) are associated with severe and persistent conduct problems in youth. However, some youth with elevated CU traits do not exhibit severe externalizing problems, and further research is needed to identify conditions under which CU traits are more versus less strongly associated with higher levels of externalizing behavior. To this end, the current preregistered study examined whether internalizing problems, five-factor model personality traits, and parenting practices moderated associations between CU traits and externalizing problems. Caregivers of 1,232 youth ages 6-18 (Mage = 11.46) reported on youths' CU traits, externalizing, internalizing, and five-factor model traits as well as on their own parenting practices. We found that the relationship between CU traits and externalizing was robust to the moderating effects of internalizing problems and parenting practices, but CU traits were more strongly related to externalizing problems at higher levels of neuroticism and at lower levels of agreeableness and conscientiousness. Results contribute to a more comprehensive understanding of externalizing problems among youth high in CU traits and may inform future longitudinal and intervention research seeking to identify factors that reduce externalizing behavior among high-CU youth.

Examining the relation among callous-unemotional traits and cortisol, alpha-amylase, and testosterone reactivity in legal system involved young men

Elevated callous-unemotional (CU) traits (e.g., lack of empathy, deficient guilt/remorse, and shallow affect) are associated with increased antisociality and distinct patterns of cognitive and emotional functioning. Previous investigations have suggested that deficits in physiological stress responses may underlie these associations, yet few studies simultaneously examine the multiple physiological systems responsible for mounting a stress response. To clarify how individuals with and without elevated CU traits respond to acute stress, the current study examined the association between CU traits and hormones released by three systems: cortisol from the hypothalamic-pituitary-adrenal (HPA) axis, alpha-amylase from the sympathetic nervous system (SNS), and testosterone from hypothalamic-pituitary-gonadal (HPG) axis. Specifically, we used fixed effect regression modeling to examine within-individual changes in each biomarker across the administration of a standardized laboratory stressor (Trier Social Stress Test) in a sample of 55 justice-involved young men (Mage= 22.84). Results indicated significant within-individual changes in cortisol, alpha-amylase, and testosterone following the stressor among those with low or average CU traits. However, those with high levels of CU exhibited no significant changes in their cortisol and testosterone levels. Furthermore, individuals with high CU traits exhibit an asymmetric stress response, such that alpha-amylase and testosterone levels were not associated with changes in cortisol levels. In sum, elevated CU traits were associated with blunted cortisol and testosterone reactivity and asymmetric response to stress. Additional work is needed to determine the behavioral and treatment implications of this distinct stress response.

The bidirectional effects of antisocial behavior, anxiety, and trauma exposure: Implications for our understanding of the development of callous–unemotional traits.

The association of anxiety and trauma with antisocial behavior in children and adolescents has long been the focus of research, and more recently this area of research has become critical to theories of the development of callous-unemotional (CU) traits. Research suggests those with elevated CU traits and anxiety (i.e., secondary CU variant) seem to show more severe externalizing behaviors and are more likely to show histories of trauma, compared to those with elevated CU and low anxiety (i.e., primary CU variant). These findings have typically been interpreted as being indicative of distinct etiological pathways to the development of CU traits. We test an alternative explanation that the higher rates of anxiety and trauma exposure in some youth with elevated CU traits are largely a consequence of their higher levels of antisocial behavior. The current study recruited a sample of 1,216 justice-involved adolescents (Mage = 15.28, SD = 1.28) from three distinct regions of the United States, who were assessed at 6, 12, 18, 24, 30, 36, 48, and 60 months following their first arrest. Using random-intercept cross-lagged models, both antisocial behavior and CU traits predicted changes in future anxiety and CU traits predicted increases in future victimization. Further, using longitudinal parallel mediation models, antisocial and aggressive behavior largely accounted for the predictive association between CU traits and anxiety and CU traits and victimization. These results support a model in which anxiety and trauma histories may be a marker of the severity of antisocial behavior displayed by youth with elevated CU traits.

A commentary on Perlstein etal. (2023): the past and future of treating youth with limited prosocial emotions.

Perlstein, Fair, Hong, and Waller (Journal of Child Psychology and Psychiatry, 2023) meta-analysis provides a critically important summary of the research on the treatment of children and adolescents with elevated callous-unemotional (CU) traits, 10 years after they were added to diagnostic criteria in the "with Limited Prosocial Emotions" specifier for conduct disorder. Their meta-analysis provides clear and convincing evidence that many treatments that reduce conduct problems in youth are also effective for children with elevated CU traits. However, their findings also indicate that CU traits are a severity indicator, in that youth high on these traits start treatment with more severe behavior problems and, despite improving with treatment, often leave treatment with more severe behavior problems. Such findings provide a clear focus for future research to adapt existing treatments to be more effective for youth with elevated CU traits. Further, the findings from the meta-analysis suggested that while treatments overall were not effective in reducing callous-unemotional traits, high-quality parenting interventions show promise for improving this outcome.

Disentangling the relationship between callous-unemotional traits and unsupportive parenting through a developmental lens.

Research suggests that unsupportive parenting practices are consistentbut modest risk factors for children's behavioral and social problems, emphasizing the importance in identifying sources of variability in children's vulnerability. To address this research direction, this study examined children's callous-unemotional (CU) traits (i.e., affective indifference; lack of guilt or empathy), as a moderator of the associations among maternal and paternal unsupportive parenting and their externalizing symptoms. Participants included 240 mothers, partners, and their children (Mage = 4.6 years; 56% girls) from diverse backgrounds (48% Black; 16% Latinx) who took part in a longitudinal multi-method study with two measurement occasions spaced 2 years apart. Findings from structural equation modeling indicated the prospective association between observational assessments of unsupportive maternal (but not paternal) parenting and residualized changes in teacher reports children's externalizing problems over 2 years was significantly moderated by maternal reports of children's callous-unemotional traits (β = -.21, p < .05). Follow-up analyses of the interaction provided support for differential susceptibility. These findings highlight that children with elevated CU traits may experience diminished susceptibility to parenting, while children with lower levels of CU traits may exhibit plasticity in response to socialization environments.

Resting-state connectivity underlying cognitive control's association with perspective taking in callous-unemotional traits

Callous-Unemotional (CU) traits are often associated with impairments in perspective taking and cognitive control (regulating goal directed behavior); and adolescents with CU traits demonstrate aberrant brain activation/connectivity in areas underlying these processes. Together cognitive control and perspective taking are thought to link mechanistically to explain CU traits. Because increased cognitive control demands modulate perspective taking ability among both typically developing samples and individuals with elevated CU traits, understanding the neurophysiological substrates of these constructs could inform efforts to alleviate societal costs of antisocial behavior. The present study uses GIMME to examine the heterogenous functional brain properties (i.e., connection density, node centrality) underlying cognitive control's influence on perspective taking among adolescents on a CU trait continuum. Results reveal that cognitive control had a negative indirect association with CU traits via perspective taking; and brain connectivity indirectly associated with lower CU traits – specifically the social network via perspective taking and conflict network via cognitive control. Additionally, less negative connection density between the social and conflict networks was directly associated with higher CU traits. Our results support the growing literature on cognitive control's influence on socio-cognitive functioning in CU traits and extends that work by identifying underlying functional brain properties.

Behavioral Improvements but Limited Change in Callous-Unemotional Traits in Adolescents Treated for Conduct Problems

Callous-unemotional (CU) traits have been linked to more severe and sustained behavior problems among adolescents. The aims of this study were to examine the treatment impact and malleability of CU traits among adolescents and explore potential moderation effects of treatment condition and CU sub-typology. A sample of 159 adolescents (45.9% girls; M age = 14.7 years, SD = 1.47) and their parents participated in a randomized controlled trial of Functional Family Therapy with three assessments (baseline, 6-months and 18-months) of behavior problems, CU traits, prosocial skills and the parent-youth relationship. Latent growth curve model (LGCM) analyses revealed that children with higher CU traits had greater reductions in aggressive and rule-breaking behavior and greater improvements in social skills (|standardized coefficients| = 0.27–0.32). Similarly, higher CU traits were linked to larger increases in parent-ratings of family cohesion and youth-ratings of maternal support (standardized coefficients = 0.26–0.27). Reliable Change Index summaries showed that CU traits remained unchanged for the majority of participants (73.6% and 72.6% had no reliable short- and long-term change, respectively). Baseline anxiety linked to CU sub-typology moderated some of the study results. Findings show that adolescents with co-occurring behavior problems and elevated CU traits can obtain improvement in behavioral and relational outcomes in out-patient treatment. Strikingly, such improvements can occur notwithstanding a limited reduction in CU traits. Future work should investigate whether the treatment gains would be more substantial and stable if treatment adjuncts modifying the CU traits themselves were concurrently deployed.

Facial reactions to emotional films in young children with conduct problems and varying levels of callous-unemotional traits.

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. 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). 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. 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.

Parent Training Adapted to the Needs of Children With Callous–Unemotional Traits: A Randomized Controlled Trial

Callous–unemotional (CU) traits designate a distinct subgroup of children with early-starting, stable, and aggressive conduct problems. Critically, traditional parenting interventions often fail to normalize conduct problems among this subgroup. The aim of this study was to test whether parent–child interaction therapy (PCIT) adapted to target distinct deficits associated with CU traits (PCIT-CU) produced superior outcomes relative to standard PCIT. In this proof-of-concept trial, 43 families with a 3- to 7-year-old child (M age = 4.84 years, SD = 1.12, 84% male) with clinically significant conduct problems and elevated CU traits were randomized to receive standard PCIT (n = 21) or PCIT-CU (n = 22) at an urban university-based research clinic. Families completed five assessments measuring child conduct problems, CU traits, and empathy. Parents in both conditions reported good treatment acceptability and significantly improved conduct problems and CU traits during active treatment, with no between-group differences. However, linear mixed-effects models showed treatment gains in conduct problems deteriorated for children in standard PCIT relative to those in PCIT-CU during the 3-month follow-up period (ds = 0.4–0.7). PCIT-CU shows promise for sustaining improvements in conduct problems for young children with conduct problems and CU traits, but requires continued follow-up and refinement.

Exposure to community violence and Callous-Unemotional traits in young children: the role of positive parenting

IntroductionStudies regarding environmental contributions on callous-unemotional (CU) traits in children have informed about the protective role of positive parenting. However, it has not been explored whether findings from these studies -mostly conducted in High-Income Countries- can be generalised to Low-Middle-Income Countries (LMICs). Exposure to community violence is common in LMICs and is associated with emotional and behavioural problems in children. Therefore, it may represent an environmental risk factor for CU traits.ObjectivesThis prospective study explores whether positive parenting has a protective role in relation to CU traits in young Colombian children whose families have been exposed to community violence.MethodsWe assessed 235 families with children at age 3.5 years, from three contrasting regions of Colombia, using observations of mother-child interactions and maternal reports of community violence at ages 3.5 and 5.0 years.ResultsHierarchical multiple linear regression models indicated that maternal positivity at 3.5 years was associated with lower CU traits at age 5.0 years only in children of families exposed to community violence (interaction term p= .001). In the exposed group maternal positivity explained 10% of the variance (β= -.34, p= .001) with low positivity associated with elevated CU traits and high positivity with low CU traits. Maternal praise was not associated with CU traits. However, maternal negativity during play was associated with elevated CU traits as a main effect.ConclusionsBased on these findings, whether or not exposure to community violence is associated with elevated CU traits depends on maternal positivity, with low positivity creating vulnerability, and high positivity, resilience.DisclosureNo significant relationships.

The Impact of Callous-Unemotional Traits on Achievement, Behaviors, and Relationships in School: A Systematic Review.

Disruptive behavior disorders (DBDs) are associated with significant academic, behavioral, and relationship challenges in the school setting. Children with co-occurring DBDs and callous-unemotional (CU) traits show a distinct pattern of early starting, chronic, and aggressive disruptive behavior and are resistant to traditional DBD interventions. There is growing evidence that CU traits have important consequences for children's school functioning. The purpose of this systematic review is to synthesize research on CU traits in school with a focus on academics, relationships, and behavior. We searched PsycINFO, PubMed, and Education Full-Text to identify 37 empirical studies that met inclusionary criteria. Findings suggest that CU traits are associated with poor academic performance, high levels of aggression and conduct problems, and difficulty forming relationships at school, often above and beyond the impact of DBDs alone. Findings and future directions are discussed including how the current study can support key stakeholders in promoting the success of students with elevated CU traits.

Longitudinal Associations between Callous-unemotional (CU) Traits and School-based Affiliative Relationships among South Korean Children

ABSTRACT Objective Callous-unemotional traits (CU) traits are characterized by low empathy, guilt, and reduced sensitivity to others’ feelings, along with a reduced drive for social affiliation. However, little is known about the relationships between CU traits and social affiliation in the school context, or the influence of gender on these associations. This study tested reciprocal associations between CU traits and school-based affiliative relationships and explored gender as a potential moderator. Method The sample included South Korean children aged 10 to 12 years (N = 218, M = 11.03, SD = .65, 52% boys). Children reported on CU traits, antisocial behavior, teacher-student relationship quality, and peer affiliation. Three-wave longitudinal cross-lagged models tested reciprocal associations between CU traits and affiliation with both teachers and peers, with multi-group modeling employed to test the moderating effect of gender. Results Higher CU traits at time 1 predicted decreases in teacher affiliation at time 2 controlling for CU traits, teacher-child affiliation, and antisocial behavior at time 1, while lower teacher-child affiliation at time 2 predicted increases in CU traits at time 3 accounting for CU traits, teacher-child affiliation, and antisocial behavior at time 2. However, there were no reciprocal associations between CU traits and teacher affiliation nor significant associations between CU traits and peer affiliation. Gender did not moderate any pathways between CU traits and teacher or peer affiliation. Conclusions Findings indicate CU traits may reduce teacher-child affiliation, potentially escalating risk for further increases in CU traits. Thus, teacher-child affiliation may represent an important target for school-based intervention for children with elevated CU traits regardless of gender.

Neurocognitive abilities associated with antisocial behavior with and without callous-unemotional traits in a community sample.

Antisocial behavior (aggression, rule breaking) is associated with lower intelligence and executive function deficits. Research has not clarified whether these associations differ with the presence of callous-unemotional (CU) traits, particularly within levels of antisocial behavior observed in the community. We examined whether antisocial behavior and CU traits were differentially associated with intelligence and executive function metrics in 474 adolescent twins (Mean age = 14.18; SD = 2.20) sampled from birth records to represent youth in the community living in neighborhoods with above average levels of poverty. Intelligence was assessed using standardized scores from the Shipley-2. Executive function was assessed using Go/No-Go and Stop Signal tasks. Neither antisocial behavior, nor CU traits alone, were associated with cognitive functioning when accounting for demographic factors. However, antisocial behavior and CU traits interacted to predict reaction time variability. At low levels of CU traits, antisocial behavior was associated with higher reaction time variability (traditionally thought to reflect worse sustained attention). At high levels of CU traits, antisocial behavior was associated with lower reaction time variability (thought to reflect better sustained attention). Elevated antisocial behavior and CU traits may be characterized by a distinct neurocognitive profile compared to elevated antisocial behavior in isolation.

Conduct Disorders and Empathy Development.

Childhood conduct disorders, a serious mental health concern, put children at risk for significant mental health problems throughout development. Elevations on callous-unemotional (CU) traits designate a subgroup of youth with conduct disorders who have unique causal processes underlying their problem behavior and are at a particularly high risk for serious impairment relative to others with these disorders. As a result, these traits have recently been integrated into major diagnostic classification systems for conduct disorders. Given that CU traits are partly defined by deficits in empathy, we review research on empathy development in typically developing children and use this research to (a) advance theories on the specific emotional deficits that may be associated with CU traits, (b) explain the severe pattern of aggressive behavior displayed by children with elevated CU traits, and (c) suggest possible ways to enhance prevention and treatment for children with conduct disorders and elevated CU traits.

Understanding the Social Relationships of Youth with Callous-Unemotional Traits Using Peer Nominations

ABSTRACT Objective The current study investigated the social and interpersonal correlates of callous-unemotional (CU) traits using peer nominations. Method Participants (N = 289) were children in Grades 3, 6, and 8 (M age = 11.47 years, 40.1% male, 64.7% self-identified racial/ethnic minority) from two public school systems in the southern United States. Participants were asked to identify peers they believed fit a number of different characteristics hypothesized to be related to CU traits, in addition to individuals they “liked most” and “liked least.” We also obtained self- and teacher ratings of CU traits and parent and teacher ratings of conduct problems (CP). Results Factor analyses extracted three dimensions from peer nominations developed from past research describing social characteristics related to CU traits—being mean and aloof (Mean/Cold), untrustworthy and not nice (Not Nice), and dominant and manipulative (Desire for Dominance). Results indicated that CU traits were significantly associated with fewer “liked most” and greater “liked least” nominations, but not after controlling for CP. In contrast, both CP and CU traits were significantly independently associated with Mean/Cold nominations, and only CU traits were associated with Not Nice nominations when controlling for CP. Conclusions The findings from the current study suggest that CU traits are largely associated with traditional indices of peer rejection because of their level of CP. However, they contribute independently to perceptions of being mean, aloof, and untrustworthy. Thus, interventions focused on strengthening the social skills of children with elevated CU traits should consider ways to change these negative peer perceptions.

Positive and negative parenting in conduct disorder with high versus low levels of callous–unemotional traits

Less is known about the relationship between conduct disorder (CD), callous-unemotional (CU) traits, and positive and negative parenting in youth compared to early childhood. We combined traditional univariate analyses with a novel machine learning classifier (Angle-based Generalized Matrix Learning Vector Quantization) to classify youth (N = 756; 9-18 years) into typically developing (TD) or CD groups with or without elevated CU traits (CD/HCU, CD/LCU, respectively) using youth- and parent-reports of parenting behavior. At the group level, both CD/HCU and CD/LCU were associated with high negative and low positive parenting relative to TD. However, only positive parenting differed between the CD/HCU and CD/LCU groups. In classification analyses, performance was best when distinguishing CD/HCU from TD groups and poorest when distinguishing CD/HCU from CD/LCU groups. Positive and negative parenting were both relevant when distinguishing CD/HCU from TD, negative parenting was most relevant when distinguishing between CD/LCU and TD, and positive parenting was most relevant when distinguishing CD/HCU from CD/LCU groups. These findings suggest that while positive parenting distinguishes between CD/HCU and CD/LCU, negative parenting is associated with both CD subtypes. These results highlight the importance of considering multiple parenting behaviors in CD with varying levels of CU traits in late childhood/adolescence.
