Indirect Effects of Early Parenting on Adult Antisocial Outcomes via Adolescent Conduct Disorder Symptoms and Callous-Unemotional Traits

Introduction to the Special Issue: Prevention Science and Youth Conduct Problems: Development, Prevention, and Treatment

This introductory article describes this Special Issue entitled Prevention Science and Youth Conduct Problems: Development, Prevention, and Treatment that is being offered in recognition of the research and scientific contributions of Dr. Robert J. McMahon. This Special Issue includes a collection of 15 original empirical research articles, systematic reviews, meta-analyses, and theoretical pieces spanning three themes consistent with Dr. McMahon's program of research: (1) risk and protective factors in the development and maintenance of youth conduct problems; (2) family based preventive and treatment interventions for youth conduct problems; and (3) multicomponent preventive and treatment interventions for youth conduct problems. Following these articles, this Special Issue contains two commentaries from experts in the fields of youth conduct problems and prevention science, as well as a reflection from Dr. McMahon. Our introduction provides a brief synopsis of each article contained in the Special Issue, identifying how these works reflect upon and were inspired by Dr. McMahon's research legacy and how they advance understanding of conduct problems. We close this introduction with thoughts regarding future research directions that will extend Dr. McMahon's impressive impact on the field of youth conduct problems.

Low Parental Empathy Predicts Callous-Unemotional Traits in Children With Enhanced Autonomic Sensitivity to the Environment

INTRODUCTION

Recent evidence suggests that autonomic nervous system functioning can reflect individual differences in sensitivity to the environment, which in turn moderates the effects of family context on psychopathic and antisocial behaviour. Although some preliminary research suggests that the coordination of the sympathetic (SNS) and parasympathetic (PNS) branches of the autonomic nervous system may reflect sensitivity to environmental influences, the majority of research to date has been limited in its focus on just one branch, and little is known about the effects of parental empathy on a child's psychopathic-like traits. This study aimed to address this gap by examining if the SNS and PNS jointly moderate the prospective contribution of parental empathy to youth psychopathic-like traits.

METHODS

Male and female children (n = 340; age = 8-10 years) from the community completed an emotion regulation task during which their skin conductance level (SCL) and respiratory sinus arrhythmia (RSA) activity were recorded. Parental cognitive, affective, and somatic empathy were reported by the caregivers. The child's psychopathic-like traits were reported by the caregiver and the child and were reassessed 1 year later.

RESULTS

Hierarchical regression indicated that after controlling for child sex, age, and concurrent CU traits, low affective empathy in parents predicted higher CU traits 1 year later in youths who exhibited reciprocal sympathetic activation (i.e., SNS activation along with PNS withdrawal), reflecting their enhanced sensitivity to the environment. No such effects were found for other psychopathic-like traits.

CONCLUSIONS

Findings suggest that reciprocal SNS reactivity may be a biological indicator for sensitivity to environmental influence and highlight the importance of examining the interactions among multiple systems to better understand the aetiology of psychopathic traits.

Modeling Adolescent Disposition Development: Age-Related Changes in Psychosocial Processes Correlated with Substance Use

PURPOSE

A model is proposed in which longitudinal changes in adolescents' dispositions increase age-related risk for the onset of substance use.

METHOD

Pooled surveys from 25 longitudinal studies were examined. Disposition was calculated from eight variables: use intentions; refusal intentions; attitudes; positive consequence beliefs; beliefs about negative consequences; descriptive peer normative beliefs; injunctive peer normative beliefs; and lifestyle incongruence. Substance use onset (past 30-day alcohol, cigarette, and marijuana use) was analyzed using participants' just prior dispositional status and recent changes in their dispositions.

RESULTS

Disposition was highly correlated with each of the measured variables. The pattern of disposition changes as adolescents grow older, revealing that younger adolescents have more positive dispositions; whereas when they grew older, negative dispositions gradually emerged among a subset of adolescents. Analyses also revealed that dispositional status and recent changes in their dispositions were strong predictors of substance use onset.

IMPLICATIONS

Better understanding the development of dispositions will aid in designing effective interventions. Subordinate variables are amenable to intervention and are recommended as the primary focus of prevention programming. Because of the developmental trajectory of dispositions, multi-year interventions are highly recommended. Whenever possible, tailored approaches that take adolescents' pre-intervention dispositions into account should be considered.

Early childhood family threat and longitudinal amygdala-mPFC circuit development: Examining cortical thickness and gray matter-white matter contrast

Early threat-associated cortical thinning may be interpreted as accelerated cortical development. However, non-adaptive processes may show similar macrostructural changes. Examining cortical thickness (CT) together with grey/white-matter contrast (GWC), a proxy for intracortical myelination, may enhance the interpretation of CT findings. In this prospective study, we examined associations between early life family-related threat (harsh parenting, family conflict, and neighborhood safety) and CT and GWC development from late childhood to middle adolescence. MRI was acquired from 4200 children (2069 boys) from the Generation R study at ages 8, 10 and 14 years (in total 6114 scans), of whom 1697 children had >1 scans. Linear mixed effect models were used to examine family factor-by-age interactions on amygdala volume, caudal and rostral anterior cingulate (ACC) and medial orbitofrontal cortex (mOFC) CT and GWC. A neighborhood safety-by-age-interaction was found for rostral ACC GWC, suggesting less developmental change in children from unsafe neighborhoods. Moreover, after more stringent correction for motion, family conflict was associated with greater developmental change in CT but less developmental change in GWC. Results suggest that early threat may blunt ACC GWC development. Our results, therefore, do not provide evidence for accelerated threat-associated structural development of the amygdala-mPFC circuit between ages 8-14 years.

Cascading Effects of the Family Context in Adolescence: Implications for Young Adult Antisocial Behavior and Intergenerational Transmission of Risk

Inspired by the tremendous impact of Robert McMahon's career, this study evaluated an intergenerational cascade model in which young adult conduct problems may serve as a risk pathway linking generation 1 (G1) parenting and family climate in adolescence with generation 2 parenting quality and family climate with their children (G2-G3). Our sample included 396 parents (Mage = 28.3; 70% women; child Mage = 3.96, 48% girls) who have participated in the PROSPER study since they were in 6th grade. Our developmental model included a random intercept cross-lagged panel model assessing bidirectional relations between family climate and effective discipline, assessed over six measurement occasions from 6th through 10th grade (G1). In turn, random intercepts for family climate and effective discipline in adolescence predicted distal outcomes: young adult antisocial behavior (assessed at ages 20, 23, and 25) and G2-G3 parenting quality (warm, lax, harsh, and abusive parenting) and family-level (cohesion, conflict, routines) functioning. Cross-lagged analyses revealed a bidirectional relation between G1 family processes: in early adolescence, higher levels of a positive family climate were associated with increases in effective discipline; in middle adolescence, the direction of effects reversed, with effective discipline predicting increases in positive family climate. In terms of cascading effects, a more positive G1 family climate was associated with reduced risk for young adult antisocial behavior, but no effect was evident for G1 effective discipline. Antisocial behavior was linked with all three aspects of G2-G3 family climate and with lower levels of parental warmth. Direct, domain-specific intergenerational links were found for G1 family climate with G2-G3 family-level functioning and G1 effective discipline with more effective G2-G3 parenting.

Is childhood lying shaped by callous-unemotional traits or does lie-telling make children more callous-unemotional? A longitudinal between- and within-person perspective

The current study aims to advance knowledge on the causal interrelationship between childhood CU traits and lying both at a between- and a within-person perspective across a significant developmental period of mid-childhood to mid-adolescence. Cross-lagged panel models and Random-intercept cross-lagged panel models were used to investigate the prospective associations between lying and the distinct subcomponents of CU traits, including Callousness, Uncaring, and Unemotional in a sample of 719 children (T1; Mage = 10.73 years, SDage = 1.38, range = 7-15 years, 54.4% girls) across four assessment points. Results supported large vulnerability effects at the between-person level across time, indicating that CU traits predominantly influence the subsequent development of lying, with Callousness and Uncaring showing most profound effects on subsequent developmental processes of lying. At the within-person level, fluctuations in CU traits and lying were overall meaningfully related, but no causal relationship could be empirically determined. These findings provide a differentiated etiological viewpoint on the intertwinement of CU traits and lying at a young age, and underscore the importance of an early identification of children with callous and uncaring tendencies in order to prevent more persistent lying in adolescence.

Dimensions of Parenting and Children's Conduct Problems: The Importance of Considering Children's Callous-Unemotional Traits

Research has clearly indicated that the development of serious behavioral problems in children and adolescents is influenced by parenting. However, recent research has refined the role of parenting by showing the importance of distinguishing between different types of parenting and in considering the role of callous-unemotional traits (CU traits) and conduct problems (CP) of the children. In the current study, we advance this research by distinguishing between emotional (e.g., parental warmth; parental hostility) and behavioral (e.g., use of positive reinforcement; inconsistent discipline/harsh discipline) aspects of parenting and by considering the way parents respond to children's emotions (i.e., coaching and dismissing). The sample consisted of 136 mothers (M = 38.09 years, SD = 4.51 years, 45.41% high school degree) with a child (age range 3-5 years) enrolled in kindergarten in central Italy. Multiple regression analyses indicated that, after controlling for level of CP, use of positive reinforcement (β = -0.31, p < 0.001) and warm feelings (β = -0.22, p < 0.05), remained associated with CU traits and punitive parenting was no longer significant. Consistent with predictions, use of positive reinforcement was no longer associated with conduct problems when controlling for CU traits and the positive associations with punitive parenting (β = 0.24, p < 0.05) and negativity (β = 0.36, p < 0.001) remained significant. These findings support the need for continued research that considers both the emotional and behavioral aspects of parenting and disentangles their associations with conduct problems and CU traits. Such research could not only advance causal theories for children with conduct problems but also help to guide more effective treatments, especially for those with elevated CU traits who often leave treatment with significant conduct problems remaining.

Pathways to substance use: Examining conduct problems and parenting behaviors from preschool to adolescence

While many studies have identified risk and protective factors of substance use (SU), few have assessed the reciprocal associations of child conduct problems (CP) and parenting practices and behaviors in the prediction of SU across development. A greater understanding of how these factors relate over time is needed to improve the timing of targeted prevention efforts. This study examined how child CP, parenting behaviors, and parents' own antisocial behavior relate from preschool to adolescence and eventuate in SU. Participants included 706 youth (70.6% male; 89.7% white) enrolled in the Michigan Longitudinal Study. Data from waves 1 (ages 3-5), 2 (ages 6-8), 3 (ages 9-11), 4 (ages 12-14), and 5 (ages 15-17) were included. A random intercept cross-lagged panel model (RI-CLPM) examined reciprocal associations between parenting practices, parents' antisocial behavior, and child CP over time (waves 1-4) and how these factors contribute to adolescent alcohol, cigarette, and marijuana use (wave 5). At the within-person level, negative parenting and parents' own antisocial behavior had a strong influence in late childhood/early adolescence. Only child CP emerged as a significant predictor of SU. Results highlight the importance of early intervention and the potential influence of parenting and child factors throughout development in the prevention of SU.

How Does Trauma Make You Sick? The Role of Attachment in Explaining Somatic Symptoms of Survivors of Childhood Trauma

Exposure to traumatic events during childhood is common, and the consequences for physical and mental health can be severe. Adverse childhood experiences (ACEs) such as physical abuse, sexual abuse, emotional abuse, and neglect appear to contribute to the onset and severity of a variety of somatic inflictions, including obesity, diabetes, cancer, and heart disease. The aim of this scoping review was to try to gain insight into how this might occur. Given the evidence of indirect (i.e., through unhealthy behaviours such as excessive drinking or poor eating habits) and direct (i.e., through its impact on the endocrine, immune, and cardiovascular systems as well as on the brain) effects of attachment on health, we examined the possibility that insecure attachment might contribute to the development of somatic symptoms in adult survivors of childhood trauma. Eleven studies met our inclusion criteria. Findings from this review suggest that insecure and disorganized attachment orientations are related to DNA damage, metabolic syndrome and obesity, physical pain, functional neurological disorder, and somatization in adults exposed to childhood trauma. We discuss the implications of this for the conceptualization and treatment of trauma and stress disorders.

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.

Parenting styles, empathy and aggressive behavior in preschool children: an examination of mediating mechanisms

Introduction

This study examined the interplay between parenting styles, empathy, and aggressive behavior in Chinese preschool children aged 3-5 years.

Methods

Data were collected from 87 participants using the Child Behavior Checklist, Children's Empathy Quotient, and Parenting Style Questionnaire, and were subsequently analyzed.

Results

The findings revealed significant age and gender differences in empathy, but not in parenting styles or aggressive behavior. Additionally, a substantial correlation was identified between authoritarian parenting style and aggressive behavior, as well as between children's empathy levels and aggressive behavior. This indicates that empathy may act as a mediator between parenting style and aggressive behavior.

Discussion

Our findings suggest that an authoritarian parenting style influences aggressive behavior both directly and indirectly through its effect on children's empathy. These results point toward the possibility that an authoritarian parenting style may stifle the development of empathy in preschool children, subsequently heightening their aggressive behavior.

Promoting Empathy and Affiliation in Relationships (PEAR) study: protocol for a longitudinal study investigating the development of early childhood callous-unemotional traits

INTRODUCTION

Children with callous-unemotional (CU) traits are at high lifetime risk of antisocial behaviour. Low affiliation (ie, social bonding difficulties) and fearlessness (ie, low threat sensitivity) are proposed risk factors for CU traits. Parenting practices (eg, harshness and low warmth) also predict risk for CU traits. However, few studies in early childhood have identified attentional or physiological markers of low affiliation and fearlessness. Moreover, no studies have tested whether parenting practices are underpinned by low affiliation or fearlessness shared by parents, which could further shape parent-child interactions and exacerbate risk for CU traits. Addressing these questions will inform knowledge of how CU traits develop and isolate novel parent and child targets for future specialised treatments for CU traits.

METHODS AND ANALYSIS

The Promoting Empathy and Affiliation in Relationships (PEAR) study aims to establish risk factors for CU traits in children aged 3-6 years. The PEAR study will recruit 500 parent-child dyads from two metropolitan areas of the USA. Parents and children will complete questionnaires, computer tasks and observational assessments, alongside collection of eye-tracking and physiological data, when children are aged 3-4 (time 1) and 5-6 (time 2) years. The moderating roles of child sex, race and ethnicity, family and neighbourhood disadvantage, and parental psychopathology will also be assessed. Study aims will be addressed using structural equation modelling, which will allow for flexible characterisation of low affiliation, fearlessness and parenting practices as risk factors for CU traits across multiple domains.

ETHICS AND DISSEMINATION

Ethical approval was granted by Boston University (#6158E) and the University of Pennsylvania (#850638). Results will be disseminated through conferences and open-access publications. All study and task materials will be made freely available on lab websites and through the Open Science Framework (OSF).

Predictive Validity of Adolescent Callous-Unemotional Traits and Conduct Problems with Respect to Adult Outcomes: High- and Low-Risk Samples

Current understanding of the predictive validity of callous-unemotional (CU) traits is limited by (a) the focus on externalizing psychopathology and antisocial behaviors, (b) a lack of long-term prospective longitudinal data, (c) samples comprised of high-risk or low-risk individuals. We tested whether adolescent CU traits and conduct problems were associated with theoretically relevant adult outcomes 12-18 years later. Participants were drawn from two studies: higher-risk Fast Track (FT; n = 754) and lower-risk Child Development Project (CDP; n = 585). FT: conduct problems positively predicted externalizing and internalizing psychopathology and partner violence, and negatively predicted health, wellbeing, and education. Three conduct problems × CU traits interaction effects were also found. CDP: CU traits positively predicted depression and negatively predicted health and education; conduct problems positively predicted externalizing and internalizing psychopathology and substance use, and negatively predicted wellbeing. CU traits did not provide incremental predictive validity for multiple adult outcomes relative to conduct problems.

Proposed Specifiers for Conduct Disorder-Short Version (PSCD-SV): Psychometric Properties, Concurrent Correlates and Parenting Predictors

The present study aims to further examine the four-factor model of psychopathy in adolescence with a new alternate model for the assessment of psychopathic traits and conduct disorder (CD): The Proposed Specifiers for Conduct Disorder-Short version (PSCD-SV). Data were collected in a sample of 414 adolescents (49.2% females) aged 12-15 at the first assessment who were then followed-up 2 years later. Results supported the usefulness of the PSCD-SV to assess the broader construct of psychopathy showing good psychometric properties, including adequate reliability and validity, while accounting for all its dimensions. In addition, the study showed close associations between psychopathic traits and adolescent behavioral, emotional and psychosocial maladjustment. Finally, the findings elucidated the PSCD's connection to parental support and psychological control, and reinforced the potential role of parenting practices as predictors that can act as mechanisms of change in the development of psychopathy. Overall, current findings shed light on conceptual and developmental models of psychopathy that may have implications for assessment, diagnostic classification, prevention, and intervention.

The Mediating Role of Callous-Unemotional Traits in the Relationship between Parental Aggression and Behavioral Problems among Chinese Preschoolers

It is well known that aggressive parenting is associated with behavioral problems among Western children in their early childhood, but this has rarely been examined among Chinese preschoolers. The purpose of this study is to explore the relationship between aggressive parenting, callous-unemotional traits (CU traits), and behavioral problems among a large Chinese preschool sample. Data were collected in Wuhu city, China, from 1879 preschoolers (54% of whom were male) with a mean age of 65.66 months (standard deviation = 9.41). Parents provided information about the frequency of aggressive parenting, children's behaviors, and demographic characteristics via an online questionnaire. Mediation models were applied to analyze the associations between aggressive parenting, CU traits, and behavioral problems. Preschoolers' age, gender, and family socioeconomic status were considered as covariates. The findings of our study revealed that higher frequencies of parental psychological and physical aggression were associated with high levels of CU traits, which were related to increased levels of preschoolers' behavioral problems. This study extends previous studies by revealing a positive relationship between aggressive parenting and behavioral problems among Chinese preschoolers via CU traits and highlights the risks of aggressive parenting. Interventions for improving parenting strategies and lessening callous-unemotional traits should be developed to help reduce behavioral problems.

The effectiveness of blended versus regular Forensic Outpatient Systemic Therapy in the treatment of juvenile antisocial behavior: a study protocol of a randomized controlled trial

BACKGROUND

Antisocial behavior during adolescence can have long-lasting negative effects and leads to high societal costs. Forensic Outpatient Systemic Therapy (Forensische Ambulante Systeem Therapie; FAST) is a promising treatment for juveniles aged 12-21 showing severe antisocial behavior. The intensity, content and duration of FAST can be adjusted to the needs of the juvenile and their caregiver(s), which is considered crucial for effective treatment. Next to the regular version of FAST (FASTr), a blended version (FASTb) in which face-to-face contacts are replaced by minimally 50% online contacts over the duration of intervention was developed during the Covid-19 pandemic. The current study will investigate whether FASTb is equally effective as FASTr, and through which mechanisms of change, for whom, and under which conditions FASTr and FASTb work.

METHODS

A randomized controlled trial (RCT) will be carried out. Participants (N = 200) will be randomly assigned to FASTb (n = 100) or FASTr (n = 100). Data collection will consist of self-report questionnaires and case file analysis, and include a pre-test at the start of the intervention, a post-test immediately after the intervention, and a six month follow-up. Mechanisms of change will be investigated using monthly questionnaires of key variables during treatment. Official recidivism data will be collected at two-year follow-up.

DISCUSSION

This study aims to improve the effectiveness and quality of forensic mental health care for juveniles with antisocial behavior by studying the effectiveness of blended care, which has not been studied before in treatment of externalizing behavior. If found to be at least as effective as face-to-face treatment, blended treatment can help meet the urgent need for more flexible and efficient interventions in this field. In addition, the proposed study aims to unravel what works for whom, knowledge urgently needed in mental health care for juveniles with severe antisocial behavior.

TRIAL REGISTRATION

This trial was registered at ClinicalTrials.gov on 07/11/2022, registration number NCT05606978.

Illuminating the origins of the intergenerational transmission of psychopathology with a novel genetically informed design

Although it is well known that parental depression is transmitted within families across generations, the etiology of this transmission remains unclear. Our goal was to develop a novel study design capable of explicitly examining the etiologic sources of intergenerational transmission. We specifically leveraged naturally-occurring variations in genetic relatedness between parents and their adolescent children in the 720 families participating in the Nonshared Environment in Adolescent Development (NEAD) study, 58.5% of which included a rearing stepparent (nearly always a stepfather). Results pointed squarely to the environmental transmission of psychopathology between fathers and children. Paternal depression was associated with adolescent depression and adolescent behavior problems (i.e., antisocial behavior, headstrong behavior, and attention problems) regardless of whether or not fathers and their children were genetically related. Moreover, these associations persisted to a subset of "blended" families in which the father was biologically related to one participating child but not to the other, and appeared to be mediated via father-child conflict. Such findings are not only fully consistent with the environmental transmission of psychopathology across generations, but also add to extant evidence that parent-child conflict is a robust and at least partially environmental predictor of adolescent psychopathology.

Genetic versus environmental influences on callous-unemotional traits in preadolescence: The role of parenting and parental psychopathology

Children with callous-unemotional (CU) traits are at risk for severe conduct problems. While CU traits are moderately heritable, parenting also predicts risk. However, few studies have investigated whether parenting factors (e.g., acceptance, conflict, parental psychopathology) moderate the etiology of CU traits, while accounting for gene-environment correlations. To address this knowledge gap, we used data from 772 twin pairs from the Adolescent Brain and Cognitive Development Study to test bivariate models that explored overlapping etiological influences on CU traits and child reports of their parenting environment. We also used gene-by-environment interaction models to test whether parenting moderated genetic versus environmental influences. There were no overlapping etiological influences on CU traits and parental acceptance, but modest genetic and non-shared environmental overlap between CU traits and family conflict. Parental acceptance and psychopathology moderated non-shared environmental influences, with stronger non-shared environmental influences on CU traits among children who experienced lower parental acceptance and greater parental psychopathology. Family conflict only moderated environmental influences when models did not covary for conduct problems. Parental acceptance and parental psychopathology may be specific environmental protective and risk factors for CU traits, whereas family conflict may represent a general environmental risk factor for both CU traits and conduct problems.

Longitudinal Associations between Parental Warmth, Harsh Discipline, Child Emotion Regulation, and ODD Dimensions

Research has yet to investigate the mediating role of emotion regulation in the relation between parental warmth and harsh discipline with oppositional defiant disorder (ODD). Further, few studies have investigated ODD as both a unitary construct and as three distinct dimensions (anger, defiance, spitefulness). Thus, the present study aimed to investigate child emotion regulation (grade 2) as a mediator of the relation between parental warmth and harsh discipline (kindergarten, grade 1, grade 2) and ODD and its dimensions (grade 3). Participants included the high-risk and normative samples from the Fast Track project (N = 753, male = 58 %, Black = 46 %). Constructs were assessed using observation and parent and teacher reports. Although results demonstrated an absence of indirect effects, emotion regulation was negatively associated with overall ODD and anger and defiance, but not spitefulness. Findings illustrate how increased attention toward the study of ODD as distinct dimensions contributes to our ability to parse out heterogeneity among children with the disorder.

Examining the potential link between child maltreatment and callous-unemotional traits in children and adolescents: A multilevel analysis

BACKGROUND

There is a great deal of research indicating that callous-unemotional traits in childhood are among the strongest predictors of adult psychopathy and psychopathic traits. As a result, there has been a recent surge of studies examining potential risk factors that may be related to the development of callous-unemotional traits.

OBJECTIVE

The current study sought to extend prior research examining potential risk factors for the development of callous-unemotional traits by estimating the extent to which child maltreatment related to callous-unemotional traits in children and adolescents.

PARTICIPANTS

To do so, the study uses a longitudinal sample of 4579 male and female youths drawn from the National Survey of Child and Adolescent Well-Being (NSCAW I) across four waves of data. Data collection ran from November 1999 to December 2006.

METHODS

A series of multilevel random-effects models were estimated in order to examine the association between child maltreatment and callous-unemotional traits.

RESULTS

The results of the analyses revealed a significant association between child maltreatment and callous-unemotional traits across all the models. Additionally, our models demonstrated that the association between child maltreatment and callous-unemotional traits may be dependent upon the biological sex of the individual with child maltreatment having a stronger effect on males than females (β = 0.15*).

CONCLUSIONS

Overall, our analyses lend support to prior research examining child maltreatment as a risk factor for the development of callous-unemotional traits in youth. We conclude by discussing the implications of our study and considerations for future research.

Selfish parents, parenting practices, and psychopathic traits in children

Parental personality and parenting behavior have been associated with the development of psychopathic traits in offspring. However, no study has examined the effect of parental dispositional selfishness on the development of psychopathic traits in offspring, and the potential mechanism underlying this relationship. To address this issue, parents' reports on their dispositional selfishness, negative and positive parenting behavior, and child's psychopathic traits were collected for a group of children from the community (n = 118, 47% male, mean age = 14.1 years). Results showed that parental selfishness was associated with grandiose-manipulative (GM), daring-impulsive (DI), and callous-unemotional (CU) traits in children. In addition, the egocentric selfishness-GM relationship was indirectly mediated by parenting behavior including lack of involvement, poor monitoring, and inconsistent discipline, whereas the association with CU traits was directly mediated by lack of involvement. These effects remained significant after controlling for child's sex, age, race, social adversity, and a prior measure of psychopathic traits. Findings provide initial empirical evidence on the effect of parental selfishness on a child's psychopathic traits, and further support to the proposition that distinct etiology may underlie different dimensions of psychopathic traits.

Personality Disorder Traits, Rorschach Performance, and Neuropsychological Functioning in the Case of a Serial Killer: The Importance of a Multilevel Approach in the Assessment of Personalities Associated with Extreme and Repetitive Violence

The present paper utilized the case study of an incarcerated serial killer ("Keith") to demonstrate how combining three assessment techniques (the Structured Clinical Interview for DSM-IV Axis II Personality Disorders, the Rorschach task, and a comprehensive battery of neuropsychological measures) within a multilevel personality assessment framework might elucidate possible personality-based underpinnings of extreme and repetitive violence-representing a "next wave" of serial killer research while also highlighting the empirical and clinical value of an empirically-neglected multilevel assessment approach. Gacono and Meloy's multimethod "levels" model was selected as a multilevel framework, and Leary's recommended examination of inter-level consistency was utilized as an integrative strategy. Results indicated marked divergencies among Keith's data levels in areas of executive abilities, psychotic symptoms, affective/emotional disconnectivity, and sexual disturbance that suggested areas for potential change (perhaps in therapy), while consistencies among levels in social cognition and object relations suggested more stable characteristics that may be resistant to modification. The application of multilevel personality assessment methods to extremely and repetitively violent persons represents an important clinical approach worthy of future study-potentially having implications for research, clinical and forensic assessment, and treatment, and advancing empirical and clinical understandings of the continuum of interpersonal violence.

Network Structure of Callous-Unemotional Traits and Conduct Disorder Symptoms Among At-Risk Youth: Multi-Informant Reports and Gender Differences

Network analytic techniques examine how items used to measure underlying constructs are related to one another and identify core characteristics. While many studies have examined the covariance of callous-unemotional (CU) traits or features and conduct disorder (CD) symptoms, the inter-item relations of these constructs and the core characteristics of the CU construct are unclear. The present study aimed to examine the network connectivity of, and between, CU features and CD symptoms. We also examined both parent-reports and youth self-reports and gender differences. CU features and CD symptoms were rated by parents (n = 814; 74% mothers; age 23-73, M age = 43.86, SD = 8.13) and their child (n = 608; 57% female; age 7-19, M age = 13.98, SD = 2.36). Network plots depicted greater connectivity (i.e., density and weights) for CU features relative to CD symptoms across both informants. However, youth-reported CU features and CD symptoms were less densely connected than parent-reports. Items commonly comprising the callousness subscale were more central and linked the two constructs together, relative to uncaring items, across informant and gender. Gender related effects indicated lower centrality for male versus female youth, and this finding was particularly evident in youth-reports. Our findings highlight relations between CU features and CD symptoms, and point to the importance of callousness items in conceptualizations of CU features among high-risk youth from both the perspective of the parent and child. We also inform understanding of gender differences in CU features for which the literature is currently limited.

Twin Differences in Harsh Parenting Predict Youth's Antisocial Behavior

In the current study, we leveraged differences within twin pairs to examine whether harsh parenting is associated with children's antisocial behavior via environmental (vs. genetic) transmission. We examined two independent samples from the Michigan State University Twin Registry. Our primary sample contained 1,030 families (2,060 twin children; 49% female; 6-10 years old) oversampled for exposure to disadvantage. Our replication sample included 240 families (480 twin children; 50% female; 6-15 years old). Co-twin control analyses were conducted using a specification-curve framework, an exhaustive modeling approach in which all reasonable analytic specifications of the data are interrogated. Results revealed that, regardless of zygosity, the twin experiencing harsher parenting exhibited more antisocial behavior. These effects were robust across multiple operationalizations and informant reports of both harsh parenting and antisocial behavior with only a few exceptions. Results indicate that the association between harsh parenting and children's antisocial behavior is, to a large degree, environmental in origin.

Callous-Unemotional Traits Do Not Predict Functional Family Therapy Outcomes for Adolescents With Behavior Problems

Despite the availability of evidence-based treatment models for adolescent behavior problems, little is known about the effectiveness of these programs for adolescents with callous-unemotional (CU) traits. Defined by lack of empathy, lack of guilt, flattened affect and lack of caring, CU traits have been linked to long-term anti-social behavior and unfavorable treatment outcomes and might be negatively related to outcomes in evidence-based programs such as Functional Family Therapy (FFT). This study used a single-group pre-post evaluation design with a sample of 407 adolescents (49.1% female, mean age = 14.4 years, SD = 1.9) receiving FFT to investigate whether outcomes in FFT are predicted by CU traits and to what extent reliable changes in CU traits can be observed. The results showed that although CU traits are related to increased problem severity at baseline, they predicted neither treatment dropout nor post-treatment externalizing behavior and family functioning. CU traits were related to diminished improvement ratings, in particular with respect to parental supervision. Reductions in CU traits were observed across the time of treatment, and these were most profound among adolescents with elevated levels of CU traits at baseline. Further research should investigate whether certain evidence-based treatment components are more suited for adolescents with CU, and if the addition of specific intervention elements for reducing CU-traits could further improve outcomes for this high-risk population.

Antisocial behaviour and teacher-student relationship quality: The role of emotion-related abilities and callous-unemotional traits

BACKGROUND

Childhood antisocial behaviour has been associated with poorer teacher-student relationship (TSR) quality. It is also well-established that youth with antisocial behaviour have a range of emotion-related deficits, yet the impact of these students' emotion-related abilities on the TSR is not understood. Furthermore, the addition of the Limited Prosocial Emotions Specifier in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) indicates that understanding the role of callous-unemotional (CU) traits for youth with antisocial behaviour problems is of particular importance.

AIMS

The aim of this study was to investigate the association between antisocial behaviour difficulties and the TSR by examining the influence of emotion-related abilities and CU traits.

SAMPLE

Twelve teachers from 10 primary schools provided anonymized information on 108 children aged 6-11 years.

RESULTS

Antisocial behaviour was associated with higher teacher-student conflict (but not closeness) as well as higher emotion lability/negativity and lower emotion understanding/empathy. Emotion lability/negativity was associated with higher teacher-student conflict (but not closeness), and emotion understanding/empathy was associated with lower teacher-student conflict and higher closeness. CU traits were associated with higher teacher-student conflict and lower teacher-student closeness (controlling for antisocial behaviour more broadly). We found no evidence of a moderating effect of CU traits or emotion-related abilities on the association between antisocial behaviour and TSR quality.

CONCLUSIONS

Interventions for behaviour difficulties should consider teacher-student relationships in the classroom. Strategies which aim to improve teacher-student closeness as well as reduce teacher-student conflict may be of particular value to students with high CU traits.
