Associations Between Callous-Unemotional (CU) Traits and EmotionRecognition Abilities in School Children: The Influence of ConductProblems and Age.

Callous-unemotional (CU) traits are associated with severe conduct problems (CP) in youth. Causal theories for CU traits focus on emotion processing deficits that interfere with empathy development. However, though CU traits are consistently associated with deficits in affective empathy (i.e., emotional reactivity), the association between CU traits and cognitive empathy, which requires accurate emotion recognition, is less clear. We hypothesize that past inconsistencies in the associations between CU traits and emotion recognition may be due to interactions with conduct problems (CP) and age. To test this, a sample (N = 258) of school children in the 3rd, 6th, and 8th grades completed a computer task that assessed facial expression recognition, while caregivers and teachers reported on CU traits and CP. Results from hierarchical linear regression analyses indicated significant interactions between CU traits and CP in their associations with overall emotion recognition and with recognition of fearful and sad faces. In each case, CP showed a non-significant negative association with emotion recognition at high levels of CU traits. However, for fear and sadness recognition, CP was positively associated with accuracy at low levels of CU traits. Significant interactions between CU traits and age also emerged for recognition of fear and sadness, such that there were non-significant negative associations between CU traits and recognition accuracy in younger children, but significant positive associations in 8th grade students. These results have multiple implications as they help to clarify past inconsistencies on the association between CU traits and emotion recognition and can aid in the development of more effective interventions to prevent or treat conduct problems in young children.

Callous-unemotional traits, cognitive functioning, and externalizing problems in a propensity-matched sample from the ABCD study.

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. 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. 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). 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.

EMOCIONALNI PROCESI KOD MALOLETNIH DELINKVENATA: KRIMINOLOŠKE IMPLIKACIJE

Juvenile delinquency represents a serious societal issue, and this paper focuses on the emotional aspects associated with it. Juvenile offences are estimated to constitute 7% of total criminal acts worldwide, with significant social consequences. Delinquents often come from dysfunctional families, abuse psychoactive substances, and experience psychiatric disorders, highlighting the complexity of this problem. The paper’s emphasis is on the emotional processes underlying delinquency, starting with emotional intelligence (EI). Research indicates a connection between low EI and juvenile delinquency, highlighting the role of emotion recognition and emotional regulation in this context. Various forms of delinquency may be linked to different aspects of emotional regulation, particularly impulsivity. The paper also considers psychopathy as a prominent personality characteristic closely related to juvenile delinquency, exploring the emotions that describe psychopathy. Factors such as manipulativeness, low empathy, and impulsivity are often present in juveniles with psychopathic traits. Additionally, in this paper, we are interested in Callous-Unemotional (CU) Taits. CU model is applied to describe the psychopathic tendencies of children and adolescents. The connection between emotions and cognition in the context of juvenile delinquency is illustrated through findings that discuss two dimensions of empathy: affective and cognitive, as well as the role of executive functions in delinquent behaviors. Finally, the importance of research seeking to explain the link between emotions and cognition is emphasized, particularly in the context of understanding personality traits responsible for such behaviors, such as psychopathy.

Child Maltreatment Increases the Risk for Callous-Unemotional Traits: A Three-Level Meta-Analytic Review.

Callous-unemotional (CU) traits are characterized by lack of remorse and guilt, lack of empathy, and shallow and deficient emotions. A growing body of research has examined the association between child maltreatment and CU traits. However, empirical findings on this association are inconclusive. Therefore, this meta-analytic review aimed to examine the overall association between child maltreatment and CU traits and potentially moderating variables. After searching five databases (Web of Science, ScienceDirect, PubMed, MEDLINE, and CNKI), a total of 37 studies (N = 26,010 participants) yielding 165 effect sizes were synthesized in three-level meta-analytic models. Results showed that child maltreatment is significantly and positively related to CU traits (mean r = .183; p < .001). Moderator analyses showed that this association is larger in females than in males, larger in community samples (r = .243) than in clinical samples (r = .073), and in terms of CU trait dimensions stronger for callousness (r = .251) than for uncaring (r = .134) and unemotional dimensions (r = .050). It is concluded that child maltreatment is a risk factor for the development of CU traits and discussed that interventions for CU traits in antisocial groups should be aware of the environmental influence of interpersonal trauma resulting from childhood maltreatment experiences.

Investigating cross-sectional and longitudinal relationships between brain structure and distinct dimensions of externalizing psychopathology in the ABCD sample.

Externalizing psychopathology in childhood is a predictor of poor outcomes across the lifespan. Children exhibiting elevated externalizing symptoms also commonly show emotion dysregulation and callous-unemotional (CU) traits. Examining cross-sectional and longitudinal neural correlates across dimensions linked to externalizing psychopathology during childhood may clarify shared or distinct neurobiological vulnerability for psychopathological impairment later in life. We used tabulated brain structure and behavioural data from baseline, year 1, and year 2 timepoints of the Adolescent Brain Cognitive Development Study (ABCD; baseline n = 10,534). We fit separate linear mixed effect models to examine whether baseline brain structures in frontolimbic and striatal regions (cortical thickness or subcortical volume) were associated with externalizing symptoms, emotion dysregulation, and/or CU traits at baseline and over a two-year period. The most robust relationships found at the cross-sectional level was between cortical thickness in the right rostral middle frontal gyrus and bilateral pars orbitalis was positively associated with CU traits (β = |0.027-0.033|, pcorrected = 0.009-0.03). Over the two-year follow-up period, higher baseline cortical thickness in the left pars triangularis and rostral middle frontal gyrus predicted greater decreases in externalizing symptoms ((F = 6.33-6.94, pcorrected = 0.014). The results of the current study suggest that unique regions within frontolimbic and striatal networks may be more strongly associated with different dimensions of externalizing psychopathology. The longitudinal findings indicate that brain structure in early childhood may provide insight into structural features that influence behaviour over time.

Daily Associations between Parental Warmth and Discipline and Adolescent Conduct Problems and Callous-Unemotional Traits.

Past longitudinal research has demonstrated links between parenting behaviors and adolescent conduct problems (CP) and callous-unemotional (CU) traits on macro timescales (e.g., years). Less is known about daily fluctuations in parenting behaviors and adolescent CP and CU traits, as well as their daily associations on a micro timescale. This study investigated thedaily reciprocal associations between three key dimensions of parenting behaviors-parental warmth, inconsistent discipline, and non-harsh discipline-and adolescent CP and CU traits, and explored potential moderating effects of person-mean levels of these parenting behaviors on within-person cross-day links. Participants included an ethnically-racially diverse low risk community sample of 86 adolescents (Mage = 14.5years, 55% female, 45% non-White) who completed daily reports over 1month regarding their perceived parenting behaviors and their own levels of CP and CU traits (2056 total observations). Results from dynamic structural equation modeling showed that at the within-person level, higher than average levels of inconsistent discipline were linked to higher than average levels of CU traits the next day. Among adolescents with higher person-mean levels of parental warmth and non-harsh discipline, daily parental warmth and non-harsh discipline were protective against CU traits. Moreover, among adolescents with higher person-mean levels of parental warmth, adolescent CU traits also evoked lower parental warmth the next day. These findings have significant implications for understanding daily fluctuations in parenting behaviors and adolescent CP and CU traits, and inform novel parenting-based interventions that capitalize on recent advances in mobile and other technology.

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.

Autonomic regulation and comorbid symptoms in children with attention deficit hyperactivity disorder.

Vagally-mediated heart rate variability (vmHRV) is regarded as transdiagnostic marker of emotion regulation and cognitive control capacity. We analysed vmHRV of children with attention deficit/hyperactivity disorder (ADHD). Based on previous research, we expected to find comorbid symptom dimensions (i.e. internalizing symptoms, conduct problems (CP), and callous unemotional (CU) traits) to relate to vmHRV measures. The sample comprised 100 (70 boys) medication naïve children with ADHD. Children were 6 to 11 years old. High frequency HRV (HF-HRV) was measured at rest and during a delay of gratification task. Additionally, sympathetic reactivity was assessed via skin conductance responses (SCR). Comorbid symptoms were assessed by parent-report questionnaires and clinical interviews. The multiple correlation between CU traits and the HF-HRV scores proved statistically significant. Higher CU traits were associated with higher HRV resting-state and response scores. CP were positively associated with the SCR score. In children with ADHD, increased CU traits might point to a comparatively less impaired self-regulation capacity in the reward-related context. The result corresponds to findings from previous studies. In the future, CU traits should be considered in analyses of autonomic regulation in ADHD.

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.

The Inventory of Callous-Unemotional Traits (ICU) self-report version: Factor structure, measurement invariance, and predictive validity in justice-involved male adolescents.

The Inventory of Callous-Unemotional Traits (ICU) is a widely used measure of callous-unemotional (CU) traits that may aid in the assessment of the diagnostic specifier "with limited prosocial emotions," which has been added to diagnostic criteria for conduct disorder. Though there is substantial support for use of the ICU total score, the scale's factor structure has been highly debated. Inconsistencies in past factor analyses may be largely attributed to failure to control for method variance due to item wording (i.e., half of the items being worded in the callous direction and half worded in the prosocial direction). Thus, the present study used a multitrait-multimethod confirmatory factor analytic approach that models both trait and method variance to test the factor structure of the ICU self-report in a clinically relevant, high-risk sample of justice-involved male adolescents (N = 1,216). When comparing the fit of empirical and theoretical models, goodness of fit indices (χ² = 1105.877, df = 190, root-mean-square error of approximation = .063, comparative fit index = .916, Tucker-Lewis index = .878, standardized root-mean-square residual = .051) provided support for a hierarchical four-factor model (i.e., one overarching callous-unemotional factor, four latent trait factors) when accounting for method variance (i.e., covarying positively worded items). This factor structure is consistent with the way the ICU was constructed and with criteria for the limited prosocial emotions specifier. In addition, measurement invariance of this factor structure across age, race, and ethnicity was supported, and the predictive validity of the ICU was supported across these demographic groups in predicting self-reported antisocial behavior and rearrests over a 5-year period following an adolescent's first arrest.

Parent-Child Interaction Therapy with Separated Parents of a 3-Year-Old Child with Conduct Problems and Callous-Unemotional Traits

Callous and unemotional (CU) traits are associated with an earlier onset of conduct problems in children. The presence of CU traits typically predicts a severe, stable, and aggressive pattern of behavior, especially when the onset of such behaviors begins in childhood. Children with conduct problems and CU continue to exhibit challenging behavior despite implementation of behavior management strategies compared to children with conduct problems alone. An emerging body of research suggests that Parent-Child Interaction Therapy (PCIT) specifically tailored to address the characteristics unique to CU traits (PCIT-CU) may be an effective intervention for children with conduct problems + CU. This case study presents the treatment of a 3-year-old boy using PCIT-CU who presents with oppositional defiant disorder (ODD), attention-deficit/hyperactivity disorder—combined presentation (ADHD-C), and CU traits. Both caregivers participated but were separated. Following the completion of treatment, conduct problems improved, parent ratings of CU traits decreased, and positive parenting practices increased. This case study adds to the growing literature in support of tailoring behavioral management training interventions for children with conduct problems + CU.

Testosterone, cortisol, and psychopathy: Further evidence with the Levenson self-report psychopathy scale and the inventory of callous unemotional traits

ABSTRACT The current study explored associations between testosterone, cortisol, and both the Levenson Self-Report Psychopathy Scale (LSRPS) and the Inventory of Callous Unemotional (ICU) traits. Data were gathered from a relatively large sample of university students (n = 522) and analyses considered direct and interactive associations between hormones and psychopathic traits, as well as interactions between these associations and the time of day at which samples were gathered and the sex of participants. Baseline cortisol had a negative association with LSRPS primary psychopathy scores. In addition, baseline cortisol interacted with the time of day in association with LSRPS total scores. Simple slopes analyses indicated cortisol had a negative association with LSRPS total scores in the morning but not the afternoon. Interactions among hormone measures were not statistically significant. There was also no evidence for the moderation of associations between hormones and psychopathic traits by sex.

Do Children with High Callous-Unemotional Traits Have Attentional Deficits to Emotional Stimuli? Evidence from a Multi-Method and Multi-Informant Study.

Callous-unemotional (CU) traits in children and adolescents are linked to severe and persistent antisocial behavior. Based on past empirical research, several theoretical models have suggested that CU traits may be partly explained by difficulties in correctly identifying others' emotional states as well as their reduced attention to others' eyes, which could be important for both causal theory and treatment. This study tested the relationships among CU traits, emotion recognition of facial expressions and visual behavior in a sample of 52 boys referred to a clinic for conduct problems (Mage = 10.29years; SD = 2.06). We conducted a multi-method and multi-informant assessment of CU traits through the Child Problematic Traits Inventory (CPTI), the Inventory of Callous-Unemotional (ICU), and the Clinical Assessment of Prosocial Emotions-Version 1.1 (CAPE). The primary goal of the study was to compare the utility of these methods for forming subgroups of youth that differ in their emotional processing abilities. An emotion recognition task assessed recognition accuracy (percentage of mistakes) and absolute dwell time on the eyes or mouth region for each emotion. Results from repeated measures ANOVAs revealed that low and high CU groups did not differ in emotion recognition accuracy, irrespective of the method of assessing CU traits. However, the high CU group showed reduced attention to the eyes of fearful and sad facial expressions (using the CPTI) or to all emotions (using the CAPE). The high CU group also showed a general increasein attention to the mouth area, but only when assessed by the CAPE. These findings provide evidence to support abnormalities in how those elevated on CU traits process emotional stimuli, especially when assessed by a clinical interview, which could guide appropriate assessment and more successful interventions for this group of youth.

Primary and Secondary Callous-Unemotional Childhood Variants in a Korean Community Sample.

Despite the growing support for the multiple developmental pathways to phenotypic callous-unemotional (CU) traits (i.e., primary, and secondary CU variants), there remains limited research on childhood manifestations of CU variants in non-Western, community samples. Using a latent profile analysis with data sourced from the longitudinal, nationwide Korean sample (N = 1597, 48.7% girls), we discerned heterogeneous groups of children, based on externalizing problems, CU traits, and emotional reactivity level. The optimal five-profile solution identified distinct subgroups: low-risk, primary CU (characterized by low emotional reactivity and externalizing problem), reactive (low CU/moderate emotion reactivity and externalizing problem), and two secondary CU groups (i.e., secondary-high CU and secondary-moderate CU; both high in emotional reactivity and externalizing problems). The two secondary CU variants demonstrated differences from the primary CU variants, in that both are high in preschool externalizing problems (age 6) and school-age conduct problems (age 11). However, the secondary-moderate CU group displayed greater levels of anxiety at age 11 compared to secondary-high CU, indicating divergent developmental trajectories of secondary CU variants. These findings expand our understanding of CU variants among Korean preschoolers and highlight the role of emotional reactivity in distinguishing such subtypes and identifying their developmental outcomes across time.

Unique versus shared neural correlates of externalizing psychopathology in late childhood.

Childhood externalizing psychopathology is heterogeneous. Symptom variability in conduct disorder (CD), oppositional defiant disorder (ODD), attention-deficit/hyperactivity disorder (ADHD), and callous-unemotional (CU) traits designate different subgroups of children with externalizing problems who have specific treatment needs. However, CD, ODD, ADHD, and CU traits are highly comorbid. Studies need to generate insights into shared versus unique risk mechanisms, including through the use of functional magnetic resonance imaging (fMRI). In this study, we tested whether symptoms of CD, ODD, ADHD, and CU traits were best represented within a bifactor framework, simultaneously modeling shared (i.e., general externalizing problems) and unique (i.e., symptom-specific) variance, or through a four-correlated factor or second-order factor model. Participants (N = 11,878, age, M = 9 years) were from the Adolescent Brain and Cognitive Development Study. We used questionnaire and functional magnetic resonance imaging data (emotional N-back task) from the baseline assessment. A bifactor model specifying a general externalizing and specific CD, ODD, ADHD, and CU traits factors demonstrated the best fit. The four-correlated and second-order factor models both fit the data well and were retained for analyses. Across models, reduced right amygdala activity to fearful faces was associated with more general externalizing problems and reduced dorsolateral prefrontal cortex activity to fearful faces was associated with higher CU traits. ADHD scores were related to greater right nucleus accumbens activation to fearful and happy faces. Results give insights into risk mechanisms underlying comorbidity and heterogeneity within externalizing psychopathology. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Reduced prosocial motivation and effort in adolescents with conduct problems and callous-unemotional traits.

Prosocial behaviours - acts that benefit others - are of crucial importance for many species including humans. However, adolescents with conduct problems (CP), unlike their typically developing (TD) peers, demonstrate markedly reduced engagement in prosocial behaviours. This pattern is particularly pronounced in adolescents with CP and high levels of callous-unemotional traits (CP/HCU) who are at increased risk of developing psychopathy in adulthood. While a substantial amount of research has investigated the cognitive-affective mechanisms thought to underlie antisocial behaviour, much less is known about the mechanisms that could explain reduced prosocial behaviours in adolescents with CP. Here we examined the willingness to exert effort to benefit oneself (self) and another person (other, prosocial condition) in children with CP/HCU, CP and lower levels of CU traits (CP/LCU) and their TD peers. The task captured both prosocial choices, and actual effort exerted following prosocial choices, in adolescent boys aged 11-16 (27 CP/HCU; 34 CP/LCU; 33 TD). We used computational modelling to reveal the mechanistic processes involved when choosing prosocial acts. We found that both CP/HCU and CP/LCU groups were more averse to initiating effortful prosocial acts than TD adolescents - both at a cognitive and at a behavioural level. Strikingly, even if they chose to initiate a prosocial act, the CP/HCU group exerted less effort following this prosocial choice than other groups. Our findings indicate that reduced exertion of effort to benefit others may be an important factor that differentiates adolescents with CP/HCU from their peers with CP/LCU. They offer new insights into what might drive low prosocial behaviour in adolescents with CP, including vulnerabilities that may particularly characterise those with high levels of CU traits.

Maltreatment and parenting in youth with primary and secondary callous‐unemotional traits: Anxiety matters

AbstractBackgroundYouth with conduct disorder (CD) and high callous‐unemotional (CU) traits are not a homogenous group and can be disaggregated into primary and secondary subgroups. However, there are inconsistencies in defining primary and secondary subgroups, with some studies using anxiety, others using maltreatment and still others using both features to identify subgroups. There is a paucity of work comparing primary and secondary subgroups with typically developing (TD) youth on experiences of maltreatment and parenting as well as a lack of studies investigating sex differences.MethodsIn a large sample of TD youth (n = 946, 66% female) and youth with CD (n = 885, 60% female), we used latent profile analysis in youth with CD aged between 9 and 18 years to address four aims: (i) to demonstrate how primary and secondary subgroup membership differs when anxiety, maltreatment, or both are used as continuous indicators, (ii) to compare primary and secondary subgroups with TD youth on abuse and neglect measures, and (iii) to compare primary and secondary subgroups with TD youth on parenting experiences, and (iv) to examine whether the results were consistent across sexes.ResultsAnxiety without maltreatment yielded the best fitting and most theoretically interpretable classification of primary and secondary subgroups across both sexes (Bayesian information criterion = 17832.33, Entropy = 0.75, Lo‐Mendell‐Rubin: p &lt; 0.01). Compared with TD youth, youth with primary and secondary CU traits experienced greater levels of abuse and neglect (p &lt; 0.001, η2p = 0.04−0.16) and maladaptive parenting practices (p &lt; 0.001, η2p = 0.04−0.13). Youth with primary and secondary CU traits were equally high on levels of abuse, neglect, and maladaptive parenting (all p values &gt;0.05).ConclusionsWe provide evidence that anxiety and maltreatment cannot be used interchangeably to identify youth with primary versus secondary CU traits. Anxiey yielded the best fitting and most theoretically interpretable classifications across both sexes. Our results signify the need for researchers and clinicians to adopt a unified approach to defining primary and secondary subgroups of CU traits using anxiety in both sexes.

The role of threat sensitivity, social affiliation, and left-behind experience in shaping adolescent callous-unemotional and borderline personality traits

Exploring callous-unemotional (CU) and borderline personality disorder (BPD) traits during adolescence is crucial due to its role in the emergence of personality pathologies. Recent research highlights threat sensitivity and social affiliation as fundamental factors in the etiology of broader interpersonal dysfunctions in personality disorders. Further studies are needed to explore the contributions of these factors to CU and BPD traits, while considering specific parental risk factors within distinct cultural contexts. This study examines the effects of threat sensitivity, social affiliation, and left-behind experience (LBE) on CU and BPD traits in 563 Chinese adolescents. We found that the interaction between threat sensitivity and social affiliation significantly predicts CU traits in adolescents without LBE, where reduced social affiliation amplifies the association between low threat sensitivity and CU traits. Conversely, LBE and a strong need for social affiliation intensify the association between increased threat sensitivity and BPD traits. These findings highlight the specific contributions of dispositional factors to CU and BPD traits, offering insights into their divergent pathways. By elucidating the nuanced interplay of dispositional and parental risk factors, this study enhances our understanding of the predictors of adolescent personality disorders and emphasizes the need for targeted interventions tailored to these dynamics.

Educator Knowledge of Childhood Conduct Problems and Callous-Unemotional Traits.

Research evaluating mental health literacy (MHL) of adults who support children with mental health difficulties is relatively scarce. To date, no studies have investigated educator knowledge of conduct problems and callous-unemotional (CU) traits. This is a significant gap in the literature since conduct problems are among the most prevalent childhood mental disorders, while CU traits are associated with poor academic, behavioral, and social outcomes in school settings. In the current study, we assessed educators' knowledge of the characteristics and management of conduct problems and CU traits. Participants were N = 390 preschool and primary/elementary school educators (Mage = 38.62 years, SD = 11.66; 91% woman-identifying; 71% White) who completed a Knowledge Test and survey assessing educator characteristics and various student-educator outcomes. Averaged across items, educators scored 57.1% on the Knowledge Test. We identified gaps in educator knowledge with respect to identifying characteristics associated with distinct domains of externalizing difficulties and evidence-based management strategies. Educators' years of experience and accreditation status were not associated with knowledge. Paraeducators had significantly lower knowledge scores than teachers and leadership. Unexpectedly, greater knowledge was not associated with better student-teacher relationship quality or more positive perceptions of students with conduct problems. Findings support the need for universal MHL programs focused on conduct problems and CU traits, especially among paraeducators, while also suggesting that more intensive interventions may be required to improve educator-student relationship quality.
