Violent Video Game Exposure and Cyberbullying in Early Adolescents: A Latent Moderated Mediation Model.

Violent video game exposure (VVGE) is a significant predictor of adolescent cyberbullying perpetration. However, little is known about the mediating and moderated mechanisms between them. This study examined the mediating role of moral disengagement between VVGE and cyberbullying perpetration as well as the moderating role of callous-unemotional (CU) traits on those associations. A total of 2,523 Chinese adolescents (Mage = 13.22, SD = 1.60, 48.4 percent girls) participated this study. Structural equation modeling showed that VVGE was significantly related to cyberbullying perpetration and moral disengagement play a mediating role between them. Latent moderated structural equation modeling showed that CU traits strengthened the effect of VVGE on moral disengagement and of VVGE on cyberbullying perpetration. Results further showed that the mediating effect of moral disengagement was more prominent for youths who have higher levels of CU traits. Interventions to reduce moral disengagement and CU traits among adolescents may interrupt the effect of VVGE to cyberbullying perpetration.

Hostile and threatening interpretation biases in adolescent inpatients are specific to callous-unemotional traits and social anxiety

Psychopathological syndromes, such as disruptive behavior and anxiety disorders in adolescence, are characterized by distorted cognitions and problematic behavior. Biased interpretations of ambiguous social situations can elicit both aggressive and avoidance behavior. Yet, it is not well understood whether different interpretation biases are specific to different syndromes, or whether they can co-occur. We assessed both hostile and threatening interpretation biases in identical social situations, and proposed that they are uniquely related to callous-unemotional (CU) traits and social anxiety, respectively. We also explored the role of gender and age herein. The sample consisted of 390 inpatients between 10 and 18 years of age with a variety of psychiatric disorders. Hostile and threatening interpretations were assessed with the Ambiguous Social Scenario Task (ASST) consisting of 10 written vignettes. Both CU-traits and social anxiety were assessed with self-report questionnaires. Results showed that, overall, CU-traits were related to more hostile interpretations, whereas social anxiety was related to more threatening interpretations. In addition, in boys, hostile and threatening interpretations correlated significantly positive with each other. Age was not related to interpretation biases. Together, these results generally support the content-specificity of interpretation biases in concepts relevant to disruptive behavior disorders and anxiety disorders, and indicate that different interpretation biases can co-occur specifically in boys.

Callous-Unemotional Traits in Adolescents' Daily Life: Associations with Affect and Emotional and Conduct Problems.

Intensive longitudinal methods (e.g., daily diary) inform understanding of dynamic processes by parsing within-person state-like fluctuations from stable between-person trait-like differences. In this exploratory study, we investigated whether self-reported callous-unemotional (CU) traits (callousness, uncaring) demonstrated daily fluctuations, as well as whether daily CU traits were associated with multiple forms of daily emotional and behavioral functioning. A sample of 99 adolescents (55.8% female; Mage = 14.60 years) provided baseline information and completed a naturalistic 30-day diary reporting on CU traits, positive and negative affect, and emotional and conduct problems in their daily lives. Dynamic structural equation modeling revealed that many CU traits items showed within-person autoregressive and cross-lagged links; however, there was substantial between-person variation in within-person fluctuations across items. At the subscale level, cross-day associations were observed between callousness and uncaring, conduct problems and uncaring, positive affect and callousness, negative affect and emotional problems, and emotional problems and negative affect. By harnessing intensive longitudinal data, our findings provide preliminary state-level evidence of CU traits, as well as functional information with regards to CU traits and emotional and behavioral problems in daily life. We consider the implications of our findings in terms of informing future CU traits intensive longitudinal evaluations.

Commentary: Optimism and guidance for improving treatment effects among children with callous-unemotional traits - reflections on Perlstein et al. (2023).

Callous-unemotional (CU) traits have increasingly received attention as a potential predictor and outcome of treatment for children with conduct problems. The results of Perlstein etal. (2023) offer the first meta-analytic evidence against the long-held belief that CU traits confer treatment resistance. The results also suggest that children with conduct problems and CU traits require something more or different to achieve treatment outcomes commensurate with their conduct problems-only peers. In this commentary, I reflect on how treatment adaptations for children with conduct problems and CU traits have attempted to achieve this goal, emphasizing that more work is needed to maximize improvement in putative mechanisms and mediators of treatment-related change. In this way, I argue that Perlstein etal. (2023) offer both optimism and guidance for improving treatment effects among children with conduct problems and CU traits.

Conceptualizing Callous-Unemotional Traits in Chinese Preschoolers: Factor Structure and Measurement Invariance.

With the increasing use of the Inventory of Callous Unemotional Traits (ICU) to examine callous-unemotional traits, few studies have explicitly tested the most appropriate ICU factor structures and measurement invariance in Chinese children at preschool age. This study was conducted with a large community sample of 2055 Chinese preschoolers (53.6% male, M age = 62.23 months, SD = 9.91) to test the most appropriate model of ICU and the measurement invariance across parent gender, child gender, as well as age. The confirmatory factor model suggested that the two-factor model with 11 items (ICU-11) is the best-fitting model for a Chinese preschool sample, which includes a callousness and an unemotional factor. The results from measurement invariance revealed that the factor structures were invariant across child gender, as well as child age and parental gender. The finding suggested that the ICU-11 may be a useful tool for evaluating CU traits in Chinese preschoolers.

Exploring the Relationship between Callous-Unemotional Traits and Implicit Attitudes toward Violence.

Past research has associated callous-unemotional traits (CU) in young people with serious conduct problems and antisocial behavior. However, whether CU traits influence implicit attitudes toward violence remains largely unexplored. We assess this hypothesis in two independent samples: a sample of youth with no criminal records (Study 1, N = 86), and in a sample of young offenders (Study 2, N = 61). Both groups were not compared due to theoretical (very different demographics) and statistical reasons (the total sample was insufficient to be able to reach the statistical power required in the comparison of both groups). Further, we use an implicit procedure to examine whether CU traits modulate wanting for violent stimuli. Across two samples of youth, we found little evidence of an association between CU traits and implicit violent cognition. In youth with no criminal records, implicit attitudes toward violence were related to the unemotional factor of CU traits, but unrelated to other factors and to a global CU traits score. CU traits were not associated with implicit attitudes toward violence in young offenders. The latter finding was mirrored in the implicit wanting task. Overall, our findings cast some doubts on the adequacy of implicit measures to assess implicit violent cognition in youth with CU traits. We discuss potential methodological limitations of this research (e.g., characteristics of the sample and performance in the implicit procedures) that may impact our results.

Fearlessness as an Underlying Mechanism Leading to Conduct Problems: Testing the Intermediate Effects of Parenting, Anxiety, and callous-unemotional Traits.

This study investigates whether the longitudinal association between fearlessness and conduct problems (CP) is mediated by warm and harsh parenting, parent-child conflict, anxiety, and callous-unemotional (CU) traits. The constructs under investigation were assessed at five different time points, spanning a period of eight years. A multi-informant approach was followed, collecting data from parents and teachers (N = 2,121; 47% girls). The structural equation model pointed to both direct and indirect pathways between fearlessness and CP. Specifically, findings suggested that Time 1 fearlessness (age 3-5 years) increased the likelihood of Time 2 (age 4-6 years) harsh parenting and Time 3 (age 5-7 years) parent-child conflict. Further, fearlessness was positively associated with Time 4 (age 8-10) callous-unemotional traits and Time 5 (age 11-13) CP. The total indirect effect from fearlessness to CP through these variables was significant, although the specific indirect effect from fearlessness to CU traits to CP accounted for most of the variance. Warm parenting and anxiety did not mediate the association between fearlessness and CP. In addition to the identified pathways connecting fearlessness to CP, findings pointed to the existence of multiple developmental pathways to future CP, as well as gender differences in longitudinal associations.

Bystanders' reactions to animal abuse in relation to psychopathy, empathy with people and empathy with nature.

Social and academic interest in animal abuse has recently increased thanks to greater awareness of the importance of biodiversity in promoting sustainability. The redefinition of human-animal relationships, in the context of the fight against speciesism and the defense of veganism, has also contributed to this greater attention. Moreover, public awareness of animal rights has strengthened social reactions to violence against animals, though there are still some social sectors that are indifferent to these changes. Thus, better knowledge of the psychological mechanisms underlying reactions to animal abuse could contribute to better informal, social control of such abuse. The main aim of this study is to analyze the relationships between psychopathy, empathy with people, and empathy with nature arising from people's reactions to protected and domestic animal abuse and illegal dumping. Also, as previous studies have shown differences between men and women, both in animal abuse and in personality traits, thus gender is taken into account when analyzing these relationships. A total of 409 people, resident in a highly environmentally protected territory, participated in this study. They were aged between 18 and 82 years old and 49.9% women. Participants were asked about assigned punishments, as well as the probability of intervening personally and/or calling the police, in relation to ten scenarios, based on press releases, describing one of three types of transgression of environmental laws: abuse of protected animals, abuse of domestic animals or illegal dumping. They also responded to Spanish adaptations of the Inventory of Callous Unemotional Traits, the Basic Empathy Scale, the Dispositional Empathy with Nature Scale, and the Social Desirability Scale. Each participant was randomly given ten scenarios corresponding to just one transgression type but all the personality scales. Results show that people's reactions were greater for abuse of domestic than protected animals or for illegal dumping, irrespective of gender. Empathy with nature was related to the reaction against animal abuse more than empathy with people and psychopathy. Results are discussed highlighting the need for future research into similarities and differences between animal abuse and other types of environmental offences, which have many victims but no single being suffering.

Altered functional connectivity of the amygdala across variants of callous-unemotional traits: A resting-state fMRI study in children and adolescents

Over the past years, research has shown that primary (high callousness and low anxiety) and secondary (high callousness and anxiety) variants of CU traits may be associated with opposite amygdala activity (hypo- and hyper-reactivity, respectively). However, their differences in amygdala functional connectivity remains largely unexplored. We conducted a Latent Profile Analysis on a large sample of adolescents (n = 1416) to identify homogeneous subgroups with different levels of callousness and anxiety. We then performed a seed-to-voxel connectivity analysis on resting-state fMRI data to compare subgroups on connectivity patterns of the amygdala. We examined the results in relation to conduct problems to identify potential neural risk factors. The Latent Profile Analysis revealed four subgroups, including the primary and secondary variants, anxious, and typically developing adolescents. The seed-to-voxel analyses showed that the primary variant was mainly characterized by increased connectivity between the left amygdala and left thalamus. The secondary variant exhibited deficient connectivity between the amygdala and the dorsomedial prefrontal cortex, temporo-parietal junction, premotor, and postcentral gyrus. Both variants showed increased connectivity between the left amygdala and the right thalamus but exhibited opposite functional connectivity between the left amygdala and the parahippocampal gyrus. Dimensional analyses indicated that conduct problems may play a mediating role between callousness and amygdala-dmPFC functional connectivity across youths with already high levels of callousness. Our study highlights that both variants differ in the functional connectivity of the amygdala. Our results support the importance of disentangling the heterogeneity of adolescents at risk for conduct problems in neuroimaging.

Antisocial behavior is associated with reduced frontoparietal network efficiency in youth.

Youth antisocial behavior (AB) is associated with deficits in socioemotional processing, reward and threat processing and executive functioning. These deficits are thought to emerge from differences in neural structure, functioning and connectivity, particularly within the default, salience and frontoparietal networks. However, the relationship between AB and the organization of these networks remains unclear. To address this gap, the current study applied unweighted, undirected graph analyses to resting-state functional magnetic resonance imaging data in a cohort of 161 adolescents (95 female) enriched for exposure to poverty, a risk factor for AB. As prior work indicates that callous-unemotional (CU) traits may moderate the neurocognitive profile of youth AB, we examined CU traits as a moderator. Using multi-informant latent factors, AB was found to be associated with less efficient frontoparietal network topology, a network associated with executive functioning. However, this effect was limited to youth at low or mean levels of CU traits, indicating that these neural differences were specific to those high on AB but not CU traits. Neither AB, CU traits nor their interaction was significantly related to default or salience network topologies. Results suggest that AB, specifically, may be linked with shifts in the architecture of the frontoparietal network.

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.

Psychopathy and callous-unemotional traits in adolescence: A systematic review of cultural inclusion and meta-analysis of fMRI neural correlates

ObjectivesThe past 15 years has witnessed an increase in neuroimaging examining individuals with psychopathic traits, including adolescent populations. Neuroimaging findings have identified a wide range of structural and functional abnormalities associated with psychopathy or callous-unemotional (CU) traits that have lacked consistency. Even with this increase in attention, neuroimaging research on psychopathy has not given proper attention to the role of cultural factors as a source of heterogeneous findings. Aims: Accordingly, the present study is a systematic review and coordinate based meta-analysis (CBMA) that seeks to add to the existing literature in two important ways. First, by focusing exclusively on the consistency of neuroimaging outcomes for adolescents with psychopathy/CU traits, and second, by reporting the prevalence of cultural group inclusion within this body of research. Methods: The systematic review consisted of 52 articles, published or authored prior to June 2021, 19 of which met inclusion criteria for the meta-analysis. Results: Out of the 52 adolescent articles, 98% reported the gender makeup of their sample; however, most articles reported only the number of male adolescents in their sample. Most articles (61.5%) reported at least one racial/ethnic group membership for their sample; however, almost 40% of articles did not report any information regarding the race/ethnicity of their sample. Three articles reported neuroimaging results for female participants and no articles reported results for racial/ethnic minority group members. Meta-analytic results revealed adolescents with psychopathy/CU traits had decreased brain activity in the anterior cingulate, insula, thalamus/hypothalamus, and increased activity in the prefrontal cortex. Conclusions: To our knowledge, the present study is the only systematic review of cultural inclusion and meta-analysis of functional neural correlates within neuroimaging research on adolescents with psychopathy/CU traits. Results highlight several important implications and areas for future direction for the improvement of cultural inclusion within neuroimaging research and its incorporation into the courtroom.

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.

Conception and Development of the Warmth/Affection Coding System (WACS): A Novel Hybrid Behavioral Observational Tool for Assessing Parent-to-Child Warmth.

A vast body of research and theory underscores the importance of parental warmth/affection (hereby 'warmth' and 'warmth/affection' are used interchangeably) as a distinct relational process that is fundamental to core developmental processes including parent-child attachment, socialization, emotion recognition and responsivity, and empathic development. The increasing focus on parental warmth as a viable transdiagnostic and specific treatment target for Callous-Unemotional (CU) traits highlights the critical need for a reliable and valid tool for measuring this construct within clinical contexts. However, existing assessment methods have limitations in their ecological validity, clinical utility, and the comprehensiveness of their coverage of core warmth subcomponents. In response to this clinical and research need, the observational Warmth/Affection Coding System (WACS) was developed to comprehensively measure parent-to-child warmth/affection. This paper chronicles the conception and development of the WACS, which adopts a hybrid approach of utilizing both microsocial and macro-observational coding methods to capture key verbal and non-verbal subcomponents of warmth that are currently underrepresented or poorly captured by existing assessment tools. Recommendations for implementation and future directions are also discussed.

Affective theory of mind impairments underlying callous-unemotional traits and the role of cognitive control

ABSTRACT Affective theory of mind (aToM) impairments associated with the youth antisocial phenotype callous-unemotional (CU) traits predict antisocial behaviour above CU traits alone. Importantly, CU traits associate with decrements in complex but not basic aToM. aToM is modulated by cognitive control and CU traits associate with cognitive control impairments; thus, cognitive control is a plausible mechanism underlying aToM impairments in CU traits. Because cognitive control is dependent on the availability of cognitive resources, youth with CU traits may have difficulty with allocating cognitive resources under greater demands that impact complex aToM. To test this, 81 participants (ages 12–14, Female = 51.8%, Male = 48.2%) were recruited to complete a behavioural paradigm that involved an initial aToM task with complex and basic emotions followed by placing additional demands on cognitive control and a final repeat of the same aToM task. Results indicate adolescents higher in CU traits had intact basic aToM but less accuracy in complex aToM that worsened after taxing cognitive control; and this load only required a short duration to account for ToM decrements (200 ms [range 150–1600 ms]). These results demonstrate CU traits association with cognitive control limitations that impact complex aToM. This may partially explain antisocial behaviour associated with CU traits.

Cognitive Mechanisms Underlying Prosocial Decision Making in Callous-Unemotional Traits.

Callous-unemotional (CU) traits are characterized by a lack of prosocial emotions, which has been demonstrated with prosocial behavior paradigms. While shaping our understanding of prosocial behavior in youth with CU traits, most of this work relies on outcomes that don't reliably capture cognitive processes during prosocial behavior. Examining prosocial cognitive processes can cue researchers into cognitive mechanisms underlying core impairments of CU traits. Drift diffusion modeling is a valuable tool for elucidating more precise outcomes of latent cognitive processes during forced choice tasks such as drift rate (information accumulation toward a decision boundary) and threshold separation (amount of information considered) as well as metrics outside of the decision-making processing including bias (starting point in decision process) and non-decision time (cognitive processes outside of choice). In a sample of 87 adolescents (12-14, 49% female) we applied diffusion modeling to a prosocial behavior task in which participants either accepted or rejected trials where a real monetary value was given to them and taken away from a charity (self-serving trial) or money was given to a charity and taken from them (donation trial). Results revealed that CU traits associated with information accumulation toward accepting self-serving trials. Exploratory sex differences suggested males trended toward rejecting donation trials and females considered more information during self-serving trials. CU trait associations were independent of conduct problems. Results suggest a unique cognitive profile that are differentiated by sex at higher CU traits when making prosocial decisions involving knowledge accumulation toward self-serving decisions.

Proactive and reactive aggression: Developmental trajectories and longitudinal associations with callous-unemotional traits, impulsivity, and internalizing emotions.

Research on proactive and reactive aggression has identified covariates unique to each function of aggression, but hypothesized correlates have often not been tested with consideration of developmental changes in or the overlap between the types of aggression. The present study examines the unique developmental trajectories of proactive and reactive aggression over adolescence and young adulthood and tests these trajectories' associations with key covariates: callous-unemotional (CU) traits, impulsivity, and internalizing emotions. In a sample of 1,211 justice-involved males (ages 15-22), quadratic growth models (i.e., intercepts, linear slopes, and quadratic slopes) of each type of aggression were regressed onto quadratic growth models of the covariates while controlling for the other type of aggression. After accounting for the level of reactive aggression, the level of proactive aggression was predicted by the level of CU traits. However, change in proactive aggression over time was not related to the change in any covariates. After accounting for proactive aggression, reactive aggression was predicted by impulsivity, both at the initial level and in change over time. Results support that proactive and reactive aggression are unique constructs with separate developmental trajectories and distinct covariates.

Specific interpretation biases as a function of social anxiety and callous-unemotional traits in a community and a clinical adolescent sample

BackgroundThreatening and hostile interpretation biases are seen as causal and maintaining mechanisms of childhood anxiety and aggression, respectively. However, it is unclear whether these interpretation biases are specific to distinct problems or whether they are general psychopathological phenomena. The specificity versus pervasiveness of interpretation biases could also differ depending on mental health status. Therefore, in the current study, we investigated whether social anxiety and callous-unemotional (CU) traits were uniquely related to threatening and hostile interpretation biases, respectively, in both a community and a clinical sample of adolescents.MethodsA total of 161 adolescents between 10 to 15 years of age participated. The community sample consisted of 88 participants and the clinical sample consisted of 73 inpatients with a variety of psychological disorders. Social anxiety and CU-traits were assessed with self-report questionnaires. The Ambiguous Social Scenario Task was used to measure both threatening and hostile interpretations in response to written vignettes.ResultsResults showed that social anxiety was uniquely related to more threatening interpretations, while CU-traits were uniquely related to more hostile interpretations. These relationships were replicated for the community sample. For the clinical sample, only the link between social anxiety and threatening interpretations was significant. Explorative analyses showed that adolescents with externalizing disorders scored higher on hostile interpretations than adolescents with internalizing disorders.ConclusionsOverall, these results support the content-specificity of threatening interpretation biases in social anxiety and of hostile interpretation biases in CU-traits. Better understanding the roles of interpretation biases in different psychopathologies might open avenues for tailored prevention and intervention paradigms.

Childhood Trauma and Cyberbullying Perpetration: The Mediating Role of Callous-Unemotional Traits

ABSTRACT Throughout the years, cyberbullying has been explored and connected to experiences of childhood trauma (CT) and high levels of callous-unemotional (CU) traits. This study aims to explore differences between cyberbullying perpetrators and non-perpetrators and explore the mediate role of CU traits between CT and cyberbullying perpetration (CBP). A cross-sectional study was conducted with 7139 participants (3728 girls; 52.2%), aged 10–22 years, of whom 276 (59.8% male) self-reported cyberbullying perpetration. Propensity score matching was used to select a sample of 276 adolescents’ non-perpetrators with similar characteristics, in order to compare cyberbullying perpetrators with non-perpetrators. Results showed that CBP was more predominant among boys and middle adolescents. Callousness trait partially mediates the relation between all the studied dimensions of CT and CBP. Uncaring traits partially mediated the relation between emotional, physical, and sexual abuse. CU traits (i.e., callousness and uncaring) mediated the relation between physical, and sexual abuse, and physical and emotional neglect. This study gives a better understanding of the underlying mechanisms of the relation between CT and CBP, which allows professionals to have a different evaluation when considering intervention programs.

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.
