In the present study, the authors investigated whether callous and unemotional (CU) traits designated a distinct and important group of adolescent sex offender. A sample of 150 detained adolescents (mean age = 15.89, SD = 1.53) with a current sexual offense disposition was assessed with a self-report measure of CU traits and through extensive assessments of the characteristics of their sexual offending behaviors using self-report interviews and file review. Results indicated that after controlling for the severity of their history of impulsive/antisocial behaviors, offenders high on CU traits had a greater number of sexual offense victims, used more violence with their victims, and engaged in more sexual offense planning than those low on these traits. The 2 groups did not differ greatly on the age of, gender of, or relationship with their victims. [ABSTRACT FROM AUTHOR]

This study examined parent and child reports of parenting practices separately to predict child and parent reports of child externalizing and internalizing features, as well as delinquent activity. Participants included 98 children (51 male, 47 female) from a community sample, aged 9-15 at the beginning of the study. Results revealed that child reports of parenting practices were significantly correlated with a greater number of indices of delinquency and conduct problems than were parent reports. Child reports of parenting also showed some association with delinquency at three yearly follow-ups, whereas parent reports did not. Finally, reports of negative parenting from both informants were concurrently related to internalizing characteristics. Implications for child assessment and planning interventions for children and parents are discussed. [ABSTRACT FROM AUTHOR]

Research has suggested that childhood-onset conduct problems (CPs) are more strongly related to individual predispositions, whereas adolescent-onset CP is more strongly associated with social factors, such as peer delinquency. Neighborhood disadvantage (ND) increases the risk for associating with deviant peers. Thus, peer delinquency could mediate the relationship between ND and adolescent-onset CP. This mediational hypothesis has not been tested previously. We tested this hypothesis in 1,127 justice-involved adolescent males using self-reported delinquency and official arrest records over 3 years after the youth's first arrest as outcomes. Predictors were self-reported and census-derived indicators of ND and self-reported peer delinquency. Age of onset moderated the associations between self-reported ND and arrests and between self-report of peer delinquency and arrests. In both cases, the association was stronger for those with adolescent-onset CP. Peer delinquency mediated all relationships between ND and CP. Our results also showed some unexpected differences in associations depending on whether self-reported ND or census-derived indicators were used as predictors. Specifically, census-derived ND was negatively related to self-reported offending, which could be due to the use of an arrested sample and the need for youth in more advantaged neighborhoods to show a more severe pattern of antisocial behavior to be arrested.

The Face-to-Face Still-Face (FF-SF) procedure has been a popular paradigm to understand infant behavior. The current study examines the validity of mothers' behavior during the Still-Face phase of the FF-SF, especially the quality of her neutral face and its impact on infant arousal (N = 358 ethnically-diverse mother-infant dyads, Mean infant age = 223 days, SD = 27 days). Results showed that more than half of the mothers in the sample breached one or more Still-Face phase instructions; however, mothers' breaches of the Still-Face instructions were unrelated to infant arousal (Skin Conductance Responses) during the FF-SF. Additionally, facial analysis revealed that along with a neutral quality to the Still-Face, mothers also displayed significant levels of facial emotion during the Still-Face phase. Higher levels of scared and/or sad expressions during the Still-Face were associated with higher infant arousal during the Still-Face phase. The current study helps us to understand the real-life implementation of the Still-Face during the Face-to-Face Still-Face paradigm. Results indicate that mothers show considerable non-compliance with Still-Face phase instructions, and the infant arousal levels are associated with emotional expressions contaminating the quality of mothers' neutral faces., (© 2024 International Congress of Infant Studies.)

Antisocial and illegal behavior generally declines as youth approach adulthood, but there is significant individual variation in the timing of the peak and decline of offending from adolescence to young adulthood. There are two primary research questions in the present study. First, are there subgroups of youth who follow similar patterns of offending over the nine years after their first arrest? Second, what baseline factors predict which youth will follow each pattern of offending? Data were drawn from the Crossroads study, which includes a sample of racially and ethnically diverse boys who were interviewed regularly for 9 years following their first arrest. Boys were between 13 and 17 years old at the start of the study and were approximately 24-25 years old at the final interview. Trajectories were measured with youths' self-reported offending using latent class growth analysis (LCGA). Results indicated that there were four subgroups of youth: a stable low group (55%), an escalating group (23%), a short-term recidivist group (15%), and a persistently high group (7%). Several baseline factors distinguished the groups. In particular, the results indicated that youth who were informally processed after their first arrest were more likely to be in the low offending group than any of the other LCGA groups. Age at first arrest, peer delinquency, exposure to violence, substance use, callous-unemotional traits, physical aggression, and perceptions of police legitimacy were also significantly related to group membership. Results suggest that certain risk factors identified after youths' first arrest may predict which youth continue to offend and which desist., (© 2024 The Authors.

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., (© 2024.

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.

With high rates of violence exposure among justice-involved youth, it is critical to identify factors that might impact the likelihood of youth engaging in violence themselves. One such factor is sensitivity to context, which describes how sensitive youth are to experiences in their environment. Using an ethnically diverse sample of justice-involved male adolescents (47% Latino, 38% Black/African American, 15% White) aged 13-17 at the time of their first arrest, the results of this study indicate that exposure to violence was related to increased violent behavior six months later, and this effect was strongest among youth who were low in sensitivity to context. These findings may help practitioners identify which youth are at greatest risk for violence in a policy-relevant population., (© 2024 The Authors.

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 = 10.29 years; 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 increase in 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., (© 2024. The Author(s).)

Recent changes to diagnostic criteria for serious conduct problems in children and adolescents have included the presence of elevated callous-unemotional traits to define etiologically and clinically important subgroups of youth with a conduct problem diagnosis. The Clinical Assessment of Prosocial Emotions (CAPE) is an intensive assessment of the symptoms of this limited prosocial emotions specifier that uses a structured professional judgment method of scoring, which may make it useful in clinical settings when diagnoses may require more information than that provided by behavior rating scales. The present study adds to the limited tests of the CAPE's reliability and validity, using a sample of clinic-referred children ages 6-17 years of age, who were all administered the CAPE by trained clinicians. The mean age of the sample was 10.13 years ( SD = 2.64); 54% of the sample identified as male and 46% identified as female; and 67% of participants identified as White, 29% identified as Black, and 52% identified as another race/ethnicity (i.e., Asian, Hispanic/Latinx, or other). The findings indicated that CAPE scores demonstrated strong interrater reliability. The scores also were associated with measures of conduct problems and aggression, even when controlling for behavior ratings of callous-unemotional traits. Further, when children with conduct problem diagnoses were divided into groups based on the presence of the limited prosocial emotions specifier from the CAPE, the subgroup with the specifier showed more severe conduct problems and aggression. The results support cautious clinical use of the CAPE, its further development and testing, and research into ways to make its use feasible in many clinical settings.

Objective: The Inventory of Callous-Unemotional Traits (ICU) is a widely used, comprehensive measure of callous-unemotional (CU) traits. While the ICU total score is used frequently in research, the scale's factor structure remains highly debated. Inconsistencies in past factor structure research appear to be largely due to the use of small non-representative samples and failure to control for method variance (i.e., item wording direction)., Method: The current study used a multitrait-multimethod (MTMM) confirmatory factor analysis (CFA) approach that considers both trait and method variance to test the factor structure of a 22-item version of the self-report ICU in a multinational community sample of 4,683 adolescents (ages 11-17)., Results: Results showed that a hierarchical four-factor model (i.e., one overarching CU factor, four latent trait factors) that controlled for method variance (i.e., by allowing residuals from positively worded items to covary) provided the best fit ( χ2  = 2797.307, df  = 160, RMSEA=.059, CFI=.922, TLI=.888, SRMR=.045)., Conclusions: After controlling for method variance, the best-fitting factor structure is consistent with how the ICU was developed and corresponds to the four symptoms of Limited Prosocial Emotions (LPE) specifier in the DSM-5 criteria for Conduct Disorder (CD). In addition, measurement invariance of this factor structure across age (i.e., younger versus older adolescents) and sex was supported. As a result, mean differences in ICU total score across age and sex can be interpreted as reflecting true variations in these traits. Further, we documented that boys generally scored higher than girls on the ICU, and this sex difference was larger in later adolescence.

Objective: Callous-unemotional (CU) traits are associated with chronic and severe antisocial behavior. Although previous research has found that parents play an important role in the etiology and maintenance of youth CU traits, little research has examined the extent that parents' own CU traits impact the stability of their children's CU traits. The present study investigated the moderating role of maternal CU traits on developmental changes in youth CU traits., Method: A sample of 346 mother-son dyads, in which all youth were justice-involved males ( M age   = 15.81; 57.80% Latino, 20.52% White, 18.21% Black, 3.47% other race/ethnicity), across three states (California, Louisiana, and Pennsylvania) completed a semi-structured interview., Results: Youth exhibited a decrease in CU traits over 30 months. Mothers' CU traits moderated this relation, such that high maternal CU traits were associated with a smaller decrease in CU traits than low or average maternal CU traits, both when considering youth CU traits continuously and using a clinically significant cut score. The findings remained for continuous CU traits even after accounting for environmental factors (i.e., maternal warmth, maternal hostility, victimization, and witnessing violence), and these environmental factors did not vary over time., Conclusion: The results highlight the importance of maternal influence in understanding how youth CU traits change over time, and have important implications for the use of parenting and family-level interventions among justice-involved youth.

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., Competing Interests: The authors declare no conflicts of interest.

Objective: The presence of callous-unemotional (CU) traits in adolescence predisposes youth to negative behavioral and social outcomes and may be particularly damaging to youth involved in the justice system. Whereas research has shown that CU traits predict later arrest, it remains unknown whether rearrest predicts changes in CU traits and whether these associations may be modified by maternal relationship quality. The present study assessed whether being rearrested predicted changes in CU traits and whether these associations varied by maternal warmth and maternal hostility., Hypotheses: We hypothesized that self-reported CU traits would increase at data collection time points following rearrest. Further, we hypothesized that maternal warmth would buffer the negative effects of rearrest, whereas maternal hostility would not have a significant moderating effect on the associations., Method: Hypotheses were tested using a large, multisite longitudinal data set of 1,216 justice-involved male youth (Mage = 15.82 years at baseline; 47% Latino, 38% Black/African American, 15% White). Data from a series of nine interviews (across a 7-year period) were used to determine associations between rearrest at one-time point and CU traits at the subsequent time point., Results: Rearrest is associated with a significant increase in CU traits. However, these associations are not moderated by either maternal warmth or maternal hostility., Conclusions: Rearrest predicts increases in a known risk factor for healthy socioemotional development among justice-involved youths (CU traits). Moreover, the way rearrest is associated with CU traits does not change depending on maternal warmth; rearrest is associated with increases in CU traits irrespective of the quality of a youth's relationship with their mother.

Previous research indicates that youth exhibiting antisocial behavior are at risk for utilizing a disproportionate amount of health services compared to youth without these problems. The present study investigates whether being processed by the juvenile justice system and showing callous-unemotional (CU) traits independently predict health service utilization (medical and mental health service use and out-of-home placement) over and above the severity of antisocial behavior across adolescence. A total of 766 participants who had been arrested for the first time in adolescence provided data at ten appointments over a period of seven years. Results showed that self-reported antisocial behavior at the time of arrest predicted increased use of most health service use types over the next seven years (i.e. medicine prescriptions, tests for sexually transmitted infections, mental health service appointments, and out-of-home placements). All except prescription medication use remained significant when controlling for justice system processing and CU traits. Further, justice system processing added significantly to the prediction of medical service appointments. Whereas CU traits were associated with mental health service appointments and out-of-home placements, these did not remain significant when controlling for severity of antisocial behavior. These findings are consistent with prior research documenting the health care costs of antisocial behavior., (© 2024. The Author(s).)

This study investigated the associations among conduct problems, callous-unemotional (CU) traits, and indices of emotion recognition accuracy and emotion recognition bias obtained from human faces. Impairments in emotion recognition were considered within broader, impaired emotional and social functioning. The sample consisted of 293 middle-school students (51.19% girls; M age = 12.97 years, SD = 0.88 years). In general, CU traits were associated with less accuracy in recognizing emotions, especially fearful and angry faces, and such deficits in emotional recognition were not associated with conduct problems independent of CU traits. These results support the importance of studying potential deficits in the recognition of emotions other than fear. Furthermore, our results support the importance of considering the role of CU traits when studying emotional correlates of conduct problems. For children scoring high on CU traits, the emotion recognition accuracy of anger was low irrespective of the level of conduct problems, whereas in children scoring low on CU traits, less accuracy in recognizing emotions was related to increases in conduct problems. Finally, our results support the need for research to not only focus on accuracy of emotional recognition but also test whether there are specific biases leading to these inaccuracies. Specifically, CU traits were associated not only with lower accuracy in recognizing fearful faces but also with a tendency to interpret fearful faces as angry. This suggests that the emotional deficit associated with CU traits is not just a deficit in empathic concern toward others distress but also includes a tendency to overinterpret emotions as potential threats to oneself.

Maternal-infant bonding is important for children's positive development. Poor maternal-infant bonding is a risk factor for negative mother and infant outcomes. Although researchers have examined individual predictors of maternal-infant bonding, studies typically do not examine several concurrent and longitudinal predictors within the same model. This study aimed to evaluate the unique and combined predictive power of cross-sectional and longitudinal predictors of maternal-infant bonding. Participants were 372 pregnant women recruited from an Australian hospital. Data were collected from mothers at antenatal appointments (T0), following their child's birth (T1), and at a laboratory assessment when their child was 5-11-months-old (T2). Poorer bonding at T2 was predicted at T0 by younger maternal age, higher education, and higher antenatal depressive symptoms. Poorer bonding at T2 was predicted at T1 by younger maternal age, higher education, and higher postnatal depressive symptoms. Poorer bonding at T2 was predicted at T2 by younger maternal age, higher education, higher postnatal depression symptoms, higher concurrent perceived social support, and more difficult infant temperament, when controlling for child age at T2. To promote positive maternal-infant bonding, global and targeted interventions in the perinatal period may benefit from targeting maternal psychopathology, perceived lack of social support, and coping with difficult infant temperament., (© 2022.

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., (© 2023 Association for Child and Adolescent Mental Health.)

Objective: The recent addition of the callous-unemotional (CU) traits specifier, "with Limited Prosocial Emotions (LPE)," to major classification systems has prompted the need for assessment tools that aid in the identification of elevations on these traits for diagnostic purposes. The goal of the current study was to use and evaluate multiple methods for establishing cutoff scores for the multi-informant questionnaire, the Inventory of Callous-Unemotional Traits (ICU). Method: The present study compared the clinical utility of various proposed cutoff methods and scores (i.e., empirically derived cutoffs using receiver operating characteristic (ROC), normative cutoffs, and rational scoring approximations of LPE criteria) in both a longitudinal sample of justice-involved male adolescents ( N = 1,216; M age  = 15.29, SD  = 1.29) and a cross-sectional sample of school children ( N = 289; M age  = 11.47 years; SD  = 2.26). Results: Methods resulted in a range of cutoff scores with substantial diagnostic overlap and validity. Specifically, they designated justice-involved adolescents at risk for later delinquency, aggression, and rearrests, and they designated school children more likely to be rated by parents and teacher as having conduct problems and rated by peers as being rejected and mean. Conclusions: The results lead to ranges of ICU scores that have support for their validity and can help to guide clinical decisions about children and adolescents who may be elevated on CU traits.

Oppositional defiant disorder (ODD) is a disruptive behaviour disorder involving an ongoing pattern of angry/irritable mood, argumentative/defiant behaviour and vindictiveness. Onset is typically before 8 years of age, although ODD can be diagnosed in both children and adults. This disorder is associated with substantial social and economic burden, and childhood ODD is one of the most common precursors of other mental health problems that can arise across the lifespan. The population prevalence of ODD is ~3 to 5%. A higher prevalence in males than females has been reported, particularly before adolescence. No single risk factor accounts for ODD. The development of this disorder seems to arise from the interaction of genetic and environmental factors, and mechanisms embedded in social relationships are understood to contribute to its maintenance. The treatment of ODD is often successful, and relatively brief parenting interventions produce large sized treatment effects in early childhood. Accordingly, ODD represents an important focus for research, practice and policy concerning early intervention and prevention in mental health., (© 2023. Springer Nature Limited.)

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 ( M age = 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.

Contemporary theories of early development and emerging child psychopathology all posit a major, if not central role for physiological responsiveness. To understand infants' potential risk for emergent psychopathology, consideration is needed to both autonomic reactivity and environmental contexts (e.g., parent-child interactions). The current study maps infants' arousal during the face-to-face still-face paradigm using skin conductance ( n = 255 ethnically-diverse mother-infant dyads; 52.5% girls, mean infant age = 7.4 months; SD = 0.9 months). A novel statistical approach was designed to model the potential build-up of nonlinear counter electromotive force over the course of the task. Results showed a significant increase in infants' skin conductance between the Baseline Free-play and the Still-Face phase, and a significant decrease in skin conductance during the Reunion Play when compared to the Still-Face phase. Skin conductance during the Reunion Play phase remained significantly higher than during the Baseline Play phase; indicating that infants had not fully recovered from the mild social stressor. These results further our understanding of infant arousal during dyadic interactions, and the role of caregivers in the development of emotion regulation during infancy.

Youth in the juvenile justice system evince high rates of mental health symptoms, including anxiety and depression. How these symptom profiles change after first contact with the justice system and - importantly - how they are related to re-offending remains unclear. Here, we use latent growth curve modeling to characterize univariate and multivariate growth of anxiety, depression, and re-offending in 1216 male adolescents over 5 years following their first arrest. Overall, the group showed significant linear and quadratic growth in internalizing symptoms and offending behaviors over time such that levels decreased initially after first arrest followed by a small but significant upturn occurring a few years later. Crucially, multivariate growth models revealed strong positive relationships between the rates of growth in internalizing symptoms and offending behaviors such that improvements in mental health related to greater decreases in offending, and vice versa. These results highlight the reciprocal nature of internalizing and externalizing problems in adolescence, underscoring the importance of considering mental health alongside offending in the juvenile justice system.

Callous-Unemotional (CU) traits are strongly related to early-onset and severe levels of conduct problems. However, much less research has focused on their association with potential problems in adolescents' social relationships. Further, it is important to determine if CU traits explain variance in important social variables, independent of conduct problems or general personality dimensions related to sociability, like agreeableness. In the current study, we examined the association of CU traits with a range of social variables in a community sample of Italian adolescents (N = 563; 460 girls; mean age = 15.80, SD = 1.50). Measures for the social variables included assessment of peer rejection, adolescents' prosocial behaviors, satisfaction in peer relationships, and feelings of connection with school and classmates. We also obtained self-report ratings of CU traits, conduct problems (CP) and agreeableness. Analyses showed that CU traits were significantly associated with all the social variables. After controlling for CP and agreeableness, CU traits were still positively associated with ratings of peer rejection and negatively associated with prosocial behavior and satisfaction in relationships with peers. However, the negative associations with feelings of connection to school and peers were no longer significant. These findings provide further support for the clinical usefulness of CU traits and further evidence for potential targets of intervention, particularly focused on the adolescent's relational skills., (Copyright © 2023.

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.

Introduction: Although justice system involvement increases the risk of negative outcomes for adolescents, many justice-involved youth desist from crime as adults (Sampson & Laub, 2005). There are few studies examining predictors of positive development in justice-involved adolescents. In the current study, we assess the influence of maternal and peer warmth on the development of well-being in adolescents involved in the US justice system over the course of 5 years., Methods: Participants included 1216 adolescent males who experienced their first arrest. Interviews were given every year for 5 years. Well-being was measured using the EPOCH questionnaire (Kern et al., 2016) and relationship warmth was measured using a scale adapted from Conger et al. (1994). Hypotheses were tested using latent curve models with structured residuals., Results: Baseline levels of well-being were associated with maternal (β = 0.49, p < .001) and peer warmth, β = 0.52, p < .001. When an individual's maternal warmth was higher than predicted given their maternal warmth trajectory, their subsequent well-being was higher than expected given their well-being trajectory, b = 0.07, p < .001. When an individual's peer warmth was higher than predicted, their subsequent well-being was higher than expected, b = 0.06, p < .001. These relations were reciprocal, such that well-being also predicted increased maternal and peer warmth., Conclusions: These findings suggest that increasing maternal or peer warmth may have cascading effects on the well-being of justice-involved adolescents.

Background: In clinical settings, there is significant need for brief, easily-administered assessment tools for adolescent depression that can be used by mental health clinicians from a variety of training backgrounds. Existing depression screening tools do not assess for duration and consistency of symptoms, two key indicators of pathological depression., Objective: The Brief Adolescent Depression Screen (BADS) was developed to screen for major and persistent depressive disorders in adolescents in order to meet the assessment needs in an inpatient setting, and the validity of this tool was tested., Method: The current study used a sample of 396 inpatient adolescents to assess the screening utility of the BADS for detecting whether the adolescent meets criteria for a depressive diagnosis according to a well-validated semi-structured interview, as well as detecting a positive history of suicidal behavior. Further, the screening utility of this measure was compared to the utility of an established depression rating scale., Results: Analyses first determined the duration of depressive symptoms on the BADS that optimally screened for the presence of Major Depressive Disorder and Persistent Depressive Disorder. Findings indicated that, using these optimal screening cut-offs, the BADS showed a strong screening utility, resulting in a sensitivity and specificity for identifying full depressive diagnoses and a positive history of suicidal behavior with similar or greater accuracy than an established rating scale., Conclusions: These findings provide initial evidence to suggest that the BADS may be a helpful screening tool for adolescent depressive disorders in inpatient settings., Competing Interests: Competing interestsThe authors have no relevant financial or non-financial interests to disclose., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Due to the significant impairment associated with subthreshold bipolar symptomatology and the harmful effects of delayed diagnosis, there is a great need for diagnostic tools that can facilitate early identification of bipolar spectrum disorders. The Mood Disorder Assessment Schedule (MDAS) is a newly developed measure that focuses on autonomous changes in mood and energy, a key indicator of bipolar spectrum problems which is not included in current diagnostic tools for bipolar disorders. The current study tested the ability of the MDAS to identify individuals at risk for bipolar spectrum disorders. In a cross-sectional sample of 396 inpatient adolescents, the MDAS identified a group of individuals with several bipolar spectrum disorder (BSD) indicators, including greater manic and depressive symptoms, affective lability, suicidal behavior, adverse reactions to antidepressants, and a family history of bipolar disorder and suicidal behavior. When compared to a standard diagnostic interview for bipolar disorders (i.e., Kiddie Schedule for Affective Disorders and Schizophrenia [KSADS]), the MDAS yielded stronger clinical utility in its ability to identify individuals with BSD indicators. Therefore, the MDAS appears to be a promising diagnostic tool for identifying adolescents at risk for BSDs and may help facilitate earlier diagnosis and prevent harmful effects of improper treatment., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Elsevier Ltd.

Background: There are profound consequences when developing youth do not get adequate sleep. Adolescents who experience poor sleep may be more likely to engage in offending behavior. While there is a documented association between the number of hours youth sleep and their likelihood of offending, it is unclear how youths' perceptions of their sleep quality contribute to offending. Further, scholars have yet to rigorously examine the relation between sleep problems and offending in young adulthood, a developmental stage, which is both critical for desistance and in which sleep may play an important role., Methods: Using a sample of 1,216 justice-involved male youth, this study uses within-individual longitudinal methods (fixed-effects Poisson regression models) to examine the relation between changes in perceptions of sleep quality and changes in offending behavior from ages 13 to 24., Results: Increases in sleep problems are associated with increases in offending, particularly aggressive/person-related offenses, for both adolescents and young adults. This holds true even after controlling for time-varying anxiety, substance use, and violence exposure., Conclusions: Improving sleep quality may be critical for reducing aggressive behavior in at-risk adolescents and young adults. Interventions that address sleep quality, and not just quantity, may be particularly beneficial., (© 2022 Association for Child and Adolescent Mental Health.)

The current study compared the validity of self-, parent-, and teacher-report versions of the Inventory of Callous-Unemotional Traits (ICU), a widely used measure of callous-unemotional (CU) traits, at several different ages. Participants ( N = 236, 60.6% girls) were children in Grades 3, 6, and 8 ( M age = 11.55, SD = 2.23) from a public school system in the southern United States. We tested the association of all three ICU versions with several validators: parent- and teacher-reported conduct problems, peer nominations of characteristics associated with CU traits, and sociometric peer nominations of social preference. Results revealed an interaction between the ICU version and grade in the overall level of CU traits reported, with teacher-report leading to the highest ratings in sixth grade and being higher than parent-report in third grade. Furthermore, the validity of the different versions of the ICU varied somewhat across grades. Specifically, findings support the validity of both teacher- and self-report in third grade, but self-report was the only version to show strong validity in the eighth grade.

Callous-unemotional (CU) traits designate a distinct subgroup of children with early-starting, stable, and aggressive conduct problems. Critically, traditional parenting interventions often fail to normalize conduct problems among this subgroup. The aim of this study was to test whether parent-child interaction therapy (PCIT) adapted to target distinct deficits associated with CU traits (PCIT-CU) produced superior outcomes relative to standard PCIT. In this proof-of-concept trial, 43 families with a 3- to 7-year-old child (M age = 4.84 years, SD = 1.12, 84% male) with clinically significant conduct problems and elevated CU traits were randomized to receive standard PCIT (n = 21) or PCIT-CU (n = 22) at an urban university-based research clinic. Families completed five assessments measuring child conduct problems, CU traits, and empathy. Parents in both conditions reported good treatment acceptability and significantly improved conduct problems and CU traits during active treatment, with no between-group differences. However, linear mixed-effects models showed treatment gains in conduct problems deteriorated for children in standard PCIT relative to those in PCIT-CU during the 3-month follow-up period (ds = 0.4-0.7). PCIT-CU shows promise for sustaining improvements in conduct problems for young children with conduct problems and CU traits, but requires continued follow-up and refinement., (Copyright © 2022.

Adolescents who befriend drug using peers may be at risk for initiated and continued substance use. The present secondary data analysis examined how drug use homophily (i.e., similarity) in justice-involved boys' friendship groups relates to their subsequent substance use variety across a period of five years. Participants were 1216 first-time adolescent offenders (M age Baseline  = 15.29; 100% male). Multilevel model analyses revealed that, among participants who entered the study with a history of substance use, drug use homophily was associated with greater subsequent substance use variety. Among participants who entered the study without a history of substance use, this association was no longer significant. The findings have implications for guiding justice system programming aimed at decreasing adolescent offenders' substance use., (© 2022.

This study explored the generality versus specificity of two trait-liability factors for externalizing problems-disinhibition and callousness-in the concurrent and prospective prediction of symptoms of conduct disorder, attention-deficit/hyperactivity disorder (ADHD), and substance use (i.e., alcohol use disorder and history of illicit substance use). Disinhibition involves an impulsive, unrestrained cognitive-behavioral style; callousness entails a dispositional lack of social-emotional sensitivity. Participants were European adolescents from the multisite IMAGEN project who completed questionnaires and clinical interviews at ages 14 (N = 1,504, Mage = 14.41, 51.13% female) and 16 (N = 1,407, Mage = 16.46, 51.88% female). Disinhibition was related concurrently and prospectively to greater symptoms of conduct disorder, ADHD, and alcohol use disorder; higher scores on a general externalizing factor; and greater likelihood of having tried an illicit substance. Callousness was selectively related to greater conduct disorder symptoms. These findings indicate disinhibition confers broad liability for externalizing spectrum disorders, perhaps due to its affiliated deficits in executive function. In contrast, callousness appears to represent more specific liability for antagonistic (aggressive/exploitative) forms of externalizing, as exemplified by antisocial behavior. Results support the utility of developmental-ontogenetic and hierarchical-dimensional models of psychopathology and have important implications for early assessment of risk for externalizing problems.

The recent inclusion of callous-unemotional traits in the diagnostic criteria for serious conduct problems has led to renewed interest in more comprehensive integrations of the construct of psychopathy into research and clinical classification of childhood disruptive behavior disorders. There have been a number of recent reviews of research focusing the many potential benefits for this integration. However, there are also a number of issues that could reduce these benefits and even potentially lead to harmful effects. The current paper focuses on several of these issues, some of which are common when attempting to integrate research findings across areas that have been conducted independently of each other. Other issues are more specific to the construct of psychopathy. Specifically, the current paper focuses on the lack of agreement on the necessary and sufficient dimensions needed to define psychopathy, the need to consider developmental relationships among these dimensions, the implications of the different associations among the dimensions of psychopathy with conduct problems in children and adolescents, the need to consider how these dimensions relate to existing constructs used in the classification of disruptive behavior disorders, and the potential harmful effects of labeling something "a dimension of psychopathy". These issues have several clear implications for using the construct of psychopathy to guide research on and diagnostic classification of childhood disruptive behavior disorders., (Copyright © 2022 Elsevier Ltd.

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

Introduction: Poor parental monitoring has been theorized as a key risk factor for an adolescent's association with deviant peers. However, measurements of parental monitoring often only measure parental knowledge rather than parental monitoring actions, leaving the true longitudinal associations between parental monitoring and peer delinquency unclear., Methods: The current sample consisted of 1095 male justice-involved adolescents (13-17 years old at baseline collected between 2011 and 2013) from across the United States who provided survey data every 6 months for 3 years. Longitudinal associations between parental monitoring constructs (i.e., parental solicitation and monitoring rules) and peer delinquency were tested using random intercept cross-lagged panel models to investigate both between-individual associations and within-individual bidirectional effects., Results: Although parental monitoring and peer delinquency were negatively related at a between-individual level, very few within-individual directional effects were found. The few within-individual effects present indicated that parental solicitation predicted greater peer delinquency and peer delinquency predicted fewer parental monitoring rules over time., Conclusions: Current findings indicate that, while greater overall parental monitoring is associated with less peer delinquency, there is little evidence that changes in parental monitoring lead to reductions in peer delinquency over time. Results support previous findings suggesting parental monitoring should not be the sole target of intervention for reducing peer delinquency., (© 2022 The Foundation for Professionals in Services for Adolescents.)

There is tentative evidence that infants can learn preferences through evaluative conditioning to socioemotional stimuli. However, the early development of evaluative conditioning and the factors that may explain infants' capacity to learn through evaluative conditioning are not well understood. Infants (N = 319; 50.2% boys) participated in a longitudinal study where an evaluative conditioning paradigm using socioemotional stimuli was conducted on two occasions (when infants were 7 and 14 months old, on average). We tested whether repeatedly pairing neutral stimuli (triangular and square shapes) with affective stimuli (angry and happy faces) affects infants' preferences for these shapes. At both timepoints, the majority of infants did not choose the shape that was paired with happy faces, indicating that, in general, learning through evaluative conditioning was not present. However, as expected, individual differences were evident such that infants who spent more time fixating on faces compared to shapes (face-preferrers) during the conditioning trials were significantly more likely than non-face-preferrers to choose the shape paired with happy faces, and this effect strengthened with increasing age., (© 2022 Wiley Periodicals LLC.)

The triarchic model of psychopathy includes a disinhibition dimension related to externalizing outcomes, a meanness dimension pertaining to callous-unemotional traits, and a boldness dimension referring to emotional stability and high confidence in peer relationships. Some dimensions of psychopathy have been extensively investigated in samples of children and adolescents; in particular, the callous-unemotional (meanness) dimension has been associated with aggression and bullying in numerous studies. However, the other dimensions of the triarchic model have been relatively unexplored in samples of adolescents. Thus, we tested for associations between the triarchic dimensions and bullying and cyberbullying behaviors (i.e., proactive, goal-directed, and repetitive aggressive behaviors) in a sample of 580 high school students aged 14 to 19 years. Logistic regression analyses showed that (a) meanness and disinhibition scores were uniquely associated with traditional bullying, whereas only meanness was uniquely associated with cyberbullying; (b) boldness scores moderated the relationship between disinhibition and cyberbullying, such that disinhibition was related to cyberbullying only at low levels of boldness; and (c) these patterns were maintained when accounting for overall levels of conduct problems and were not moderated by the experience of victimization. Our findings suggest that the triarchic model of psychopathy can contribute to an understanding of youth engagement in bullying and cyberbullying.

The present study assessed whether cannabis use, other types of substance use, and drug-related offending changed among 1216 justice-system-involved youth after recreational cannabis legalization. Using generalized estimating equation population-averaged models, we compared youth in California, where recreational cannabis is legalized, and Pennsylvania, where recreational use is still prohibited. Results indicated that cannabis use, cannabis selling, and driving under the influences (DUIs) increased more among Pennsylvanian than Californian youth. We found no changes in alcohol or noncannabis drug use after legalization. Cigarette use did not change significantly among Pennsylvanian youth, but Californian youth exhibited decreased cigarette use after legalization. Although not directly tested in the present analysis, it is possible that changes in state-level recreational cannabis policies throughout the U.S. may contribute to more permissive attitudes toward cannabis, which leads to higher use and use-related outcomes. Future research should continue to consider the potential impacts of legalization on other types of risky and illegal behavior., (© 2022 John Wiley & Sons Ltd.)

An attentional bias toward threat has been theorized to be a normative aspect of infants' threat and safety learning, and an indicator of risk for internalizing psychopathology in older populations. To date, only four studies have examined this bias using the dot-probe task in infancy and the findings are mixed. We extended the literature by examining patterns of attention to threat in a culturally and linguistically diverse sample of infants aged 5-11 months old (N = 151) using all measures previously employed in the infant dot-probe literature. Given that an attentional bias toward threat is associated with higher risk of developing anxiety disorders later in life, we also examined how negative affect-an early correlate of later anxiety disorders-is related to attentional bias toward threat in infancy. This study was the first to use a consistent measure of negative affect across the whole sample. An eye-tracking dot-probe task was used to examine attentional bias toward threat (i.e., angry faces) relative to positive (i.e., happy faces) stimuli. Results showed that an attention bias to threat was not characteristic of infants at this age, and negative affect did not moderate the putative relationship between attention and emotional faces (angry, happy). These findings therefore suggest that attention biases to socio-emotional threat may not have emerged by 11 months old., (© 2021 International Congress of Infant Studies.)

Parental warmth and hostility are two key dimensions of parenting for child development, but the differential effects of these parenting dimensions on child prosocial and antisocial development has not been adequately investigated. The current study hypothesized that parental warmth would be uniquely related to child callous-unemotional traits and prosocial behavior, whereas parental hostility would be uniquely related to child delinquency and aggression. These hypotheses were investigated in a diverse sample of 1,216 adolescent males (13 to 17 years old, 46% Latino, 37% Black) with justice-system involvement in the 5 years following their first arrest. Hybrid models estimated within- and between-individual associations over time, while controlling for the overlap between parental warmth and hostility and between child prosocial and antisocial outcomes. Results indicated that maternal warmth showed consistent associations with callous-unemotional traits and prosocial behavior over time, whereas maternal hostility showed consistent associations with delinquency and aggression over time. Further, the findings were similar across racial and ethnic groups. Implications for developmental models of antisocial behavior, particularly for those including the role of callous-unemotional traits, are discussed.

Although prior studies have identified several risk factors for gun carrying, no prior longitudinal studies have examined a comprehensive set of explanatory factors together in within-individual change models or examined whether the predictors of gun carrying change across adolescence and early young adulthood. The present study fills these gaps by examining the predictive utility of several risk factors for gun carrying, and by examining whether any of the associations vary by age. The sample included 1216 young men who were arrested for the first time during adolescence (approximately 15 years old) and interviewed regularly for 5 years (until approximately 20 years old) after the first arrest. The outcome was youth-self-reported gun carrying and the risk factors included several variables consistent with various explanations for gun carrying (psychosocial maturity deficits; antisocial behavioral style; socialization; victimization). Research questions were addressed with fixed effects dynamic panel models (within-individual change models). Results showed that the most robust predictors of gun carrying were increased exposure to guns and gun-related violence and increased engagement in other antisocial and illegal behavior. The results emphasize the specific etiology of gun carrying and the potential social contagion effect of gun-related events. Overall, the study points to the need for prevention and intervention programs to specifically target the reduction of the real and perceived prevalence of gun-related events in young men's lives., (© 2021.

Callous-unemotional (CU) traits have recently been added to the diagnostic criteria of Conduct Disorder in the Diagnostic and Statistical Manual of Mental Disorders-Fifth edition and of conduct-dissocial and oppositional defiant disorders in the International Classification of Disease-Eleventh edition as the limited prosocial emotions specifier. This change necessitates the assessment of these traits with validated measures in both research and clinical contexts. The current study sought to validate a semi-structured diagnostic interview method, the Michigan Limited Prosocial Emotion Addendum (M-LPE) to the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, of assessing CU traits based on a recently developed clinician rating system (Clinical Assessment of Prosocial Emotions, Version 1.1) in a sample of at-risk youth. Results supported the interrater reliability of the M-LPE with moderate agreement and high reliability between raters. The M-LPE demonstrated convergent and incremental validity with CU traits and various measures of antisocial behavior. The results provide preliminary evidence for the use of a semi-structured interview assessment of CU traits in research contexts and build the foundation for further validation.

Psychopathy is a personality disorder characterized by a constellation of affective, interpersonal, lifestyle and antisocial features whose antecedents can be identified in a subgroup of young people showing severe antisocial behaviour. The prevalence of psychopathy in the general population is thought to be ~1%, but is up to 25% in prisoners. The aetiology of psychopathy is complex, with contributions of both genetic and environmental risk factors, and gene-environment interactions and correlations. Psychopathy is characterized by structural and functional brain abnormalities in cortical (such as the prefrontal and insular cortices) and subcortical (for example, the amygdala and striatum) regions leading to neurocognitive disruption in emotional responsiveness, reinforcement-based decision-making and attention. Although no effective treatment exists for adults with psychopathy, preliminary intervention studies targeting key neurocognitive disturbances have shown promising results. Given that psychopathy is often comorbid with other psychiatric disorders and increases the risk of physical health problems, educational and employment failure, accidents and criminality, the identification of children and young people at risk for this personality disorder and preventative work are important. Indeed, interventions that target the antecedents of psychopathic features in children and adolescents have been found to be effective.
