Does IQ moderate the relation between psychopathy and juvenile offending?

Psychopathology, psychopathy, body management, and undoing in youthful parricide offenders

This study of 21 youthful parricide offenders (YPOs) ages 11-21 examined the relationship between psychopathology, level of psychopathy, and crime scene behaviors, particularly two forms of "body management": (1) "body movement" and (2) "body alteration." Undoing, a form of body alteration reflecting psychological rather than practical needs, for example, to lessen guilt or symbolically reverse the killing, was present in one-third of the sample. The sample shared common characteristics with juvenile parricide offenders overall in that most of them killed one parent, were victims of chronic child abuse, had one or more psychiatric diagnoses (PTSD was most prevalent), used a firearm, and committed the killings at the family home. Unexpectedly, YPOs who were child abuse victims were not more likely to engage in undoing behaviors than non-abused youth, and over half of the youth with undoing behaviors had elevated psychopathy levels. Three-quarters of youth who moved victim bodies following the murders had elevated psychopathy levels. Similarly, all three youth who transported bodies away from the crime scene had elevated psychopathy levels and conduct disorder. None of the youth with psychotic symptoms engaged in undoing behaviors, altered victim bodies, moved bodies either within or away from the home, or had an elevated degree of psychopathy; they also most often killed using bladed weapons, whereas the nonpsychotic youth usually used firearms. Studies examining the influence of mental illness and psychopathy level on parricidal behaviors by youth are scarce, and to our knowledge this is the largest study to date investigating this area.

Psychopathy Scores Predict Recidivism in High-risk Youth: A Five-year Follow-up Study

Psychopathic traits have been associated with rearrest in adolescents involved in the criminal legal system. Much of the prior work has focused on White samples, short follow-up windows, and relatively low-risk youth. The current study aimed to evaluate the utility of the Hare Psychopathy Checklist: Youth Version (PCL:YV) for predicting general and violent felony recidivism in a large sample of high-risk, predominantly Hispanic/Latino, male adolescents (n = 254) with a five-year follow-up period. Results indicated higher PCL:YV scores and lower full-scale estimated IQ scores were significantly associated with a shorter time to felony and violent felony rearrest. These effects generalized to Hispanic/Latino adolescents (n = 193)-a group that faces disproportionate risk of being detained or committed to juvenile correctional facilities in the U.S. These results suggest that expert-rated measures of psychopathic traits and IQ are reliable predictors of subsequent felony and violent felony rearrest among high-risk male adolescents.

Psychopathy and substance use predict recidivism in women: A 7-year prospective study

Recidivism places a significant burden on society and efforts aimed at reducing cyclical criminal justice involvement are needed. This prospective study tested the utility of psychopathic traits in predicting general, felony, and substance-related rearrest in women following release from a correctional facility. The extent to which psychopathic traits offered incremental utility in predicting outcomes, above and beyond other established risk factors, including substance use disorder, was examined. Participants included 327 incarcerated adult women who completed comprehensive clinical and psychiatric assessments prior to release from correctional facilities. Psychopathic traits and lifetime substance use disorder were measured using the Hare Psychopathy Checklist-Revised (PCL-R) and Structured Clinical Interview for DSM-IV-TR Axis I Disorders, respectively. Results showed that general, felony, and substance-related rearrest following institutional release were associated with higher PCL-R Factor 2 scores, assessing lifestyle/behavioral and antisocial/developmental psychopathic traits. Additionally, when controlling for other risk factors associated with recidivism, including age at release, number of prior adult prison terms, and substance use disorder, higher PCL-R Factor 2 scores remained significantly associated with rearrest outcomes in women. Findings inform risk prediction and treatment efforts aimed at reducing recidivism in justice-involved women. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Resilience and mental health among juveniles: role of strategies for coping with stress

BACKGROUND

Mental health is an important aspect of the process of individual adaptation and development. The present study analysed the role played by resilience in mental health while taking into account both positive and negative indicators among juveniles. The aim of the first study (Study 1) is to analyse the relationship between resilience and the broadly understood mental health of juveniles admitted to youth education centres. Study 2 aimed to understand the direct and indirect role of resilience in shaping the mental health of juveniles. In the model we tested, we looked at the relationship among resilience, coping strategies, and mental well-being.

METHODS

The first study involved 201 juveniles, and the second involved 253 juveniles. Resilience was measured by the Resilience Scale-14. Coping strategies were measured with the Brief-COPE Questionnaire, and information on mental health was obtained using the Kutcher Adolescent Depression Scale, the Satisfaction with Life Scale and the Warwick-Edinburgh Mental Well-being Scale.

RESULTS

The results of both studies have shown that resilience is an important predictor of the mental health of juveniles, primarily with respect to its positive indicator. The stronger the severity of resilience, the greater the satisfaction with life and mental well-being of the juveniles surveyed. In addition, two coping strategies (seeking support from others and coping through emotions) mediated the relationship between resilience and mental well-being.

CONCLUSIONS

The results obtained indicate that work at the level of juvenile resilience leads to the strengthening of positive mental health indicators and buffering of negative indicators.

Aggressive Video Games are Not a Risk Factor for Future Aggression in Youth: A Longitudinal Study

The issue of whether video games with aggressive or violent content (henceforth aggressive video games) contribute to aggressive behavior in youth remains an issue of significant debate. One issue that has been raised is that some studies may inadvertently inflate effect sizes by use of questionable researcher practices and unstandardized assessments of predictors and outcomes, or lack of proper theory-driven controls. In the current article, a large sample of 3034 youth (72.8% male Mage = 11.2) in Singapore were assessed for links between aggressive game play and seven aggression or prosocial outcomes 2 years later. Theoretically relevant controls for prior aggression, poor impulse control, gender and family involvement were used. Effect sizes were compared to six nonsense outcomes specifically chosen to be theoretically unrelated to aggressive game play. The use of nonsense outcomes allows for a comparison of effect sizes between theoretically relevant and irrelevant outcomes, to help assess whether any statistically significant outcomes may be spurious in large datasets. Preregistration was employed to reduce questionable researcher practices. Results indicate that aggressive video games were unrelated to any of the outcomes using the study criteria for significance. It would take 27 h/day of M-rated game play to produce clinically noticeable changes in aggression. Effect sizes for aggression/prosocial outcomes were little different than for nonsense outcomes. Evidence from this study does not support the conclusion that aggressive video games are a predictor of later aggression or reduced prosocial behavior in youth.

Facets of Psychopathy, Intelligence, and Aggressive Antisocial Behaviors in Young Violent Offenders

Psychopathy continues to be a challenge in forensic contexts, and evidence of its association with destructive behaviors, such as aggressive antisocial behaviors, is extensive. However, the potential role of intelligence as moderator of the well-established association between psychopathy and aggressive antisocial behaviors has largely been neglected, despite intelligence having been independently related to both concepts. Increased knowledge of whether intelligence is relevant to this association is needed because of its possible implications on the assessment and treatment of individuals with psychopathic traits and aggressive antisocial behaviors. This study aimed to investigate the association between psychopathic traits, aggressive antisocial behaviors, and intelligence in young violent offenders and to test whether intelligence moderates the relationship between psychopathic traits and aggressive antisocial behaviors. Participants were 269 male violent offenders aged 18–25 years, assessed on the Psychopathy Checklist-Revised (PCL-R), the Life History of Aggression (LHA), and the General Ability Index from the Wechsler Adult Intelligence Scale, 3rd edition. Associations were tested with Spearman’s rho, and moderation analysis was performed through ordinary least squares regressions. The PCL-R four-facet structure was used for the analyses. We found a positive association between psychopathic traits and aggressive antisocial behaviors, and a small negative association between the Affective PCL-R facet and intelligence. In the moderation analyses, a small yet statistically significant moderation effect of intelligence on the association between the Interpersonal facet and LHA total scores was demonstrated. However, the amount of variance in the LHA total score explained by the model was very small: 2.9%. We suggest that intelligence, however, important for rehabilitation strategies and everyday functioning, is not necessarily pertinent to understanding aggressive antisocial behaviors in young offenders with psychopathic traits.

Cognitive functioning and aggressive antisocial behaviors in young violent offenders

Studies have shown that offenders have impaired cognitive abilities yet it is unclear if cognitive dysfunction per se contributes to aggressive antisocial behaviors. Our aims were to (1) determine associations between cognitive functioning and different forms of aggressive antisocial behaviors, (2) describe prevalence of, and covariates to, uneven intellectual profiles, and (3) investigate associations between cognitive functioning and age at onset of aggressive antisocial behaviors. A cohort (n = 269) of 18-25 years old male violent offenders were assessed for general intellectual functioning with the Wechsler Adult Intelligence Scales-third edition, and for executive functions with the Cambridge Neuropsychological Test Automated Battery. Only one measure of cognitive functioning - slower reaction times in a response inhibition test - was significantly correlated with higher occurrence of aggressive, but not exclusively antisocial, behaviors. Furthermore, offenders with even intellectual profiles showed more aggressive antisocial behaviors than offenders with uneven intellectual profiles. Finally, increased errors in tests of cognitive flexibility and slower reaction times in a response inhibition test were associated with a younger age at onset of general, but not exclusively violent, criminality. Overall, effect sizes were small. The findings emphasize the need of research investigating how cognitive functioning in offenders affects susceptibility to treatment interventions.

Narcissistic traits and self-esteem in children: Results from a community and a clinical sample of patients with oppositional defiant disorder

BACKGROUND

Several studies have investigated relationships between narcissism, self-esteem and behavioral problems in children. Most of these studies have been conducted in community samples, rather than in clinical referred samples. This field of research is clinically important, because data on community samples suggest that narcissism is a significant risk factor for children's behavioral problems.

METHODS

The study aimed to test the psychometric properties of the Child Narcissism Scale (CNS) in a community sample of Italian children and to explore the clinical utility of CNS in a sample of referred children with Oppositional Defiant Disorder (ODD).

RESULTS

In the community sample, the Italian version of the CNS was shown to be a normally distributed, single-factor measure of childhood narcissism with very good internal consistency. Furthermore, high levels of narcissism were associated with less self-esteem in family relationships, more parent-reported conduct problems, and less teacher-reported pro-social behaviors. In the ODD sample, high levels of narcissism were associated with more conduct problems and emotional symptoms. Low levels of self-esteem were associated with more conduct problems.

LIMITATIONS

The cross sectional design does not allow for estimates of CNS test-retest reliability and sensitivity to change, nor does it allow for interpretations that suggest temporal precedence or causality.

CONCLUSIONS

We found support for the cross-cultural utility of the CNS as a short and comprehensive self-report measure of narcissistic traits, which can be used in community and clinical samples of children, and suggested how narcissism may be involved in children's behavioral problems.

The Relation Between Callous-Unemotional Traits, Psychosocial Maturity, and Delinquent Behavior Among Justice-Involved Youth

Callous-unemotional (CU) traits are a risk factor for severe and persistent patterns of juvenile delinquency. Given the influence of CU trait assessments in justice-system settings, it is important to determine whether the predictive utility of CU traits is conditional on the absence of protective psychosocial factors. Employing a sample of justice-involved male youth (N = 1,216, M_age  = 15.29), this study examined whether psychosocial maturity (PSM) outweighs or attenuates the effect of CU traits on delinquency. Results indicated that youth with high CU traits or low PSM offended more during the year following their first arrest. Additionally, PSM moderated the relation between CU traits and offending, such that higher PSM was associated with less offending but only among low CU youth.

Research Review: What do we know about psychopathic traits in children?

BACKGROUND

Research on the topic of child psychopathy has advanced over the past decade increasing what we know.

METHOD

This qualitative review examines the research base for child psychopathy and emphasizes its three dimensions: grandiose-manipulative, callous-unemotional, and daring-impulsive. Literature is reviewed addressing the cognitive, emotional, motivational, personality, parenting, and biological correlates.

RESULTS

Support has emerged for the phenotypic construct of child psychopathy, while questions remain regarding definitional issues and key external correlates (e.g., reward and punishment processing, parenting, molecular genetics, brain imaging).

CONCLUSIONS

While the construct appears to be valid, future work should broaden its focus from callous unemotional traits to all three dimensions of the construct, enhance measurement precision, and examine dimension interactions. Such research could have important implications for CD specification for future versions of the DSM and ICD and speed etiological knowledge and clinical care for youth with conduct problems.

Stability and predictors of psychopathic traits from mid-adolescence through early adulthood

High levels of psychopathic traits in youth are associated with multiple negative outcomes including substance misuse, aggressive behavior, and criminality. Evidence regarding stability of psychopathic traits is contradictory. No previous study has examined long-term stability of psychopathic traits assessed with validated clinical measures. The present study examined the stability of psychopathic traits from mid-adolescence to early adulthood and explored adolescent factors that predicted psychopathic traits five years later. The sample included 99 women and 81 men who had consulted a clinic for substance misuse in adolescence. At an average age of 16.8 years, the adolescents were assessed using the Psychopathy Checklist: Youth Version (PCL: YV) and five years later using the PCL-Revised (PCL-R). Additionally, extensive clinical assessments of the adolescents and their parents were completed in mid-adolescence. Among both females and males, moderate to high rank-order stability was observed for total PCL and facet scores. Among both females and males, there was a decrease in the mean total PCL score, interpersonal facet score, affective facet score, and lifestyle facet score. However, the great majority of females and males showed no change in psychopathy scores over the five-year period as indicated by the Reliable Change Index. Despite the measures of multiple family and individual factors in adolescence, only aggressive behavior and male sex predicted PCL-R total scores in early adulthood after taking account of PCL:YV scores. Taken together, these results from a sample who engaged in antisocial behavior in adolescence suggest that factors promoting high psychopathy scores act early in life.

Self-Control Assessments and Implications for Predicting Adolescent Offending

Although low self-control is consistently related to adolescent offending, it is unknown whether self-report measures or laboratory behavior tasks yield better predictive utility, or if a combination yields incremental predictive power. This is particularly important because developmental theory indicates that self-control is related to adolescent offending and, consequently, risk assessments rely on self-control measures. The present study (a) examines relationships between self-reported self-control on the Weinberger Adjustment Inventory with Go/No-Go response inhibition, and (b) compares the predictive utility of both assessment strategies for short- and long-term adolescent reoffending. It uses longitudinal data from the Crossroads Study of male, first-time adolescent offenders ages 13-17 (N = 930; 46 % Hispanic/Latino, 37 % Black/African-American, 15 % non-Hispanic White, 2 % other race). The results of the study indicate that the measures are largely unrelated, and that the self-report measure is a better indicator of both short- and long-term reoffending. The laboratory task measure does not add value to what is already predicted by the self-report measure. Implications for assessing self-control during adolescence and consequences of assessment strategy are discussed.

Narcissism and Callous-Unemotional Traits Prospectively Predict Child Conduct Problems

Although narcissism and callous-unemotional (CU) traits are separable facets of psychopathy, their independent prediction of conduct problems (CP) among young children is not well known. In addition, above-average IQ was central to the original conceptualization of psychopathy, yet IQ is typically inversely associated with youth CP. We examined narcissism and CU traits as independent and prospective predictors of oppositional defiant disorder (ODD), conduct disorder (CD), and youth self-reported antisocial behavior, as well as their moderation by IQ. At baseline, parents and teachers separately rated narcissism and CU traits in 188 6-to-10-year-old children (47.9% non-White; 69.1% male; M = 7.34 years, SD = 1.09) with (n = 99) and without (n = 89) attention-deficit/hyperactivity disorder (ADHD). Approximately 2 years later, parents and teachers separately rated youth ODD and CD symptoms, and youth self-reported antisocial behavior. With control of baseline ADHD and ODD/CD symptoms, narcissism and CU traits independently and positively predicted ODD and CD symptoms at follow-up. IQ did not moderate any CP predictions from baseline narcissism or CU traits. These preliminary findings suggest that individual differences in narcissism and CU traits, even relatively early in development, are uniquely associated with emergent CP. Findings are considered within a developmental framework and the multiple pathways underlying the heterogeneity of CP are discussed.

Intelligence and Psychopathy Do Not Influence Malingering

This study examined the influence of psychopathy and intelligence on malingering in a simulated malingering design. We hypothesized that participants high in both traits would be more adept at evading detection on performance validity tests (PVTs). College students (N = 92) were first administered the Wechsler Test of Adult Reading, a reading measure that estimates intelligence, and the Psychopathic Personality Inventory-Short Form under standard conditions. They were then asked to imagine as if they had suffered a concussion a year ago and were instructed to fake or exaggerate symptoms in a believable fashion to improve their settlement as part of a lawsuit. Participants were subsequently administered a brief neuropsychological battery that included the Word Memory Test, Rey 15-Item Test with Recognition, Finger-Tapping Test, and Digit Span from the Wechsler Adult Intelligence Scale-Fourth Edition. Moderated multiple regressions with hierarchical entry were conducted. Intelligence, psychopathy, and the interaction of intelligence and psychopathy were not related to performance on any of the PVTs. In other words, participants who scored higher on intelligence and psychopathy did not perform differently on these measures compared with other participants. Though a null finding, implications of this study are discussed in terms of the broader research and clinical literature on malingering.
