Callous-Unemotional Traits Modulate Brain Drug Craving Response in High-Risk Young Offenders

Adults with psychopathy have a high propensity for substance abuse, generally starting from a young age. This investigation tested hypotheses about differences in the neural responses associated with drug craving among high-risk young offenders with histories of abuse of stimulants and other drugs as a function of psychopathic traits. Fifty-four male adolescents (44 with a history of stimulant abuse and 10 controls) incarcerated at a maximum-security facility (M age = 17.08 years) completed a drug-cue exposure task while brain hemodynamic activity was monitored using functional magnetic resonance imaging (fMRI) with a mobile MRI scanner stationed at the facility. Psychopathic traits were assessed using the Hare Psychopathy Checklist: Youth Version (PCL:YV). In the stimulant abuser group, drug cues elicited activity in classic reward circuitry. Consistent with studies of adult psychopathic traits and substance abuse, there was a negative association between PCL-YV scores and hemodynamic response related to drug craving in the amygdala and ACC in youth with a history of stimulant abuse. However, there were considerably more negative associations between the PCL:YV and hemodynamic response among youth than adults and this was primarily due to callous-unemotional traits rather than interpersonal or behavioral traits. The implications for how personality traits modulate motivations for drug-seeking behavior among adolescent offenders are discussed.     

Nipping psychopathy in the bud: an examination of the convergent, predictive, and theoretical utility of the PCL-YV among adolescent girls

Over the last decade rates of violence among adolescent girls have increased. Within high-risk contexts, urgent calls for assessment options have resulted in the extension of adult and male-based instruments to adolescent females in spite of the absence of strong empirical support. The current study evaluates the downward extension of psychopathy within a population of female juvenile offenders (N=125). The convergent and predictive validity of the Psychopathy Checklist-Youth Version (PCL-YV) were evaluated within a structural equation modeling (SEM) framework. Results indicated that while a specific component of psychopathy, deficient affective experience, was related to aggression, the effect was negated once victimization experiences were entered into the models. In addition, PCL-YV scores were not predictive of future offending, while victimization experiences significantly increased the odds of re-offending. Implications for research, policy, and clinical practice are discussed.     

Psychopathie,antisoziale Persönlichkeitsstörung und Sexualdelinquenz

In today’s field of forensic psychiatry, psychopathy is seen as a subtype of antisocial personality disorder and includes manipulative behavior, egocentric and arrogant characteristics, high-risk behavior as well as a lack of empathy. Empirical data on the prevalence of psychopathy and antisocial personality disorder among offenders greatly vary depending on the study design and the composition of the sampled population. Offenders who committed both violent and sex offenses seem to have antisocial traits with a higher probability than offenders who committed only violent or only sex offenses. In the context of criminal responsibility and risk assessment for sex offenders, antisocial and psychopathic traits have a negative impact on the prediction of recidivism. Many study results, even though not all, additionally indicate that the combination of psychopathic traits and sexual deviance (i.?e. for example a paraphilic disorder such as sexual sadism) in sex offenders may be associated with a particularly high risk to reoffend. Due to the specific interpersonal characteristics (e.?g., dominant, provocative behavior, exaggerated self-esteem), therapeutic treatment of sex offenders with antisocial and psychopathic traits is often difficult. The regular supervision by the therapist is considered to be crucial to avoid harmful relationship dynamics or distorted perception of the therapist.     

Psychopathy and comorbidity in a young offender sample: taking a closer look at psychopathy's potential importance over disruptive behavior disorders

The authors examined the construct of psychopathy as applied to 130 adolescent offenders using 3 psychopathy measures and a broad range of DSM-TV Axis I diagnoses and psychosocial problems. Measures used in the study included the following: (a) Psychopathy Checklist-Youth Version, (b) Antisocial Process Screening Device, (c) a modified version of the Self-Report Psychopathy-II scale, and (d) the Adolescent Psychopathology Scale. Results from this study offer incremental support for the construct validity of psychopathy in youth. Psychopathy evidenced better convergent and discriminant validity results than did the disruptive behavior disorders (DBDs) such as oppositional-defiant disorder (ODD) and conduct disorder (CD). Despite this finding, psychopathy scales nonetheless correlated with other forms of psychopathology at a higher rate than was expected, suggesting that comorbidity is high even when psychopathy is used as a classification scheme. Also, hierarchical multiple regression was used to determine whether psychopathy offered an improvement in the prediction of previous violent and nonviolent offenses. The results for the current study were mixed, with only the PCL-YV significantly predicting previous violent and nonviolent offenses beyond the DBDs. The findings indicate that psychopathy may offer incremental improvement over DBDs with regard to level of comorbidity and perhaps even prediction. However, simply extending the adult construct of psychopathy to youth without considering the array of psychopathology that may accompany adolescent psychopathy could be misleading.     

An Examination of Triarchic Psychopathy Constructs in Female Offenders

This study sought to expand scientific knowledge on psychopathic personality traits in female offenders by evaluating the relationship between MMPI–2–RF triarchic scales and self-reported external variables in a sample of 205 female offenders. Results indicated that boldness was inversely related to internalizing dysfunction, including suicidal behavior, psychosis, youth conduct problems, problems stemming from alcohol use, and a history of outpatient mental health treatment. Meanness was positively related to internalizing dysfunction as well as youth conduct problems, anger, prison disciplinary reports, and psychosis. Disinhibition was associated with a history of abuse in childhood, suicidal behavior, internalizing dysfunction, problems associated with alcohol and drug use, family history of mental illness, prison disciplinary reports for violence, number of previous criminal charges, and anger. Consistent with views of psychopathy as a configural condition, interactive effects of boldness with disinhibition and meanness were observed for multiple key external variables (e.g., conduct problems, substance use, nonsuicidal self-injurious behavior). This study provides further evidence for the triarchic conceptualization of psychopathy in female offenders and lends additional support for the validity of MMPI–2–RF triarchic psychopathy scales.     

Paralimbic Gray Matter Reductions in Incarcerated Adolescent Females with Psychopathic Traits

Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N?=?39; mean age?=?17.6 years). Consistent with male samples, regional gray matter volumes were negatively related to psychopathic traits in female youth offenders in limbic and paralimbic areas, including orbitofrontal cortex, parahippocampal cortex, temporal poles, and left hippocampus. These results provide evidence that psychopathic traits manifest similar neural abnormalities across sex and age.     

Predictive validity of the Psychopathy Checklist: Youth Version for general and violent recidivism

Several authors have expressed concern regarding the use of youth psychopathy assessments in determinations of risk for general and violent offending. The Psychopathy Checklist: Youth Version (PCL:YV) was completed with 182 male adolescent offenders in this prospective study (average 14.5 month follow-up) of general and violent recidivism. Both a two-factor and three-factor model of the PCL:YV significantly predicted general and violent recidivism at a predictive accuracy ranging from 68 to 63%. However, regression analyses indicated these associations were explained primarily by behavioral psychopathic symptoms, rather than interpersonal or affective traits. Implications for the use of psychopathy assessments for risk during adolescence are discussed.     

Linking adult psychopathy with childhood hyperactivity-impulsivity-attention problems and conduct problems through retrospective self-reports

The purpose of the present study was to test whether adult criminals with psychopathy diagnoses, more than those without, have histories of hyperactivity-impulsivity-attention problems (HIA) and conduct problems (CP). We compared psychopathic and nonpsychopathic violent criminal offenders on retrospective reports of conduct problems before the age of 15 and hyperactivity-impulsivity-attention problems before the age of 10. We used a sample of 186 adult men sentenced to prison in Sweden for 4 years or more for violent, nonsexual crimes. The mean age was 30.7( SD = 9.4). The results showed that a combination of childhood HIA problems and CP was typical for adult psychopathic offenders. They were four times more likely than chance to have had a combination of HIA problems and CP during childhood and only one-fifth as likely than chance to have had neither problem. Nonpsychopathic offenders, on the other hand, were five times more likely than chance to have had neither problem and only one-quarter as likely than chance to have had both problems.     

Child Psychopathy: Theories,Measurement, and Relations with the Development and Persistence of Conduct Problems

To develop more accurate explanatory and predictive models of child and adolescent conduct problems, interest has grown in examining psychopathic traits in youth. The presence or absence of these traits may help to identify unique etiological pathways in the development of antisocial behavior. The current review provides a detailed summary and analysis of (a) the conceptualization and measurement of child and adolescent psychopathy, (b) research on relations between psychopathic traits and a range of conduct problems and associated variables, (c) efforts to utilize data on child and adolescent psychopathy to delineate a subgroup of youth whose conduct problems share a relatively homogenous etiology and developmental trajectory, and (d) current challenges and limitations in the study of youth psychopathy and directions for future research efforts. Specific sections include the origins of the youth psychopathy construct, conceptualization and measurement, relations between psychopathic traits and conduct problems, relations between measures of psychopathy and measures of individual and contextual variables, efforts to identify a unique subgroup of children with conduct problems using psychopathic traits, and finally, challenges that face the field and goals for the next generation of research.     

Views of the downward extension: comparing the Youth Version of the Psychopathy Checklist with the Youth Psychopathic traits Inventory

Increasing interest in "juvenile psychopathy" has been met with scholarly debate about the validity of directly extending the adult construct of psychopathic personality disorder to youth. To inform this debate, this study of 160 serious adolescent offenders compared two alternative, adult-based conceptualizations of juvenile psychopathy: that of the Psychopathy Checklist: Youth Version (PCL:YV) and the self-report Youth Psychopathic traits Inventory (YPI). The results indicate that these two conceptualizations overlap only partially, with the YPI focusing more tightly on core interpersonal and affective features than the PCL:YV. Each conceptualization is reliable and predicts different forms of short-term institutional misbehavior. However, only the YPI possesses a theoretically coherent, inverse association with anxiety. Despite this promise, these conceptualizations of psychopathy are less strongly associated with one another than they are with psychosocial markers of developmental maturity. This raises questions about their divergent validity and ability to identify a disorder that will remain stable during the transition from adolescence into adulthood. Implications for future longitudinal research on the validity, manifestations, and course of juvenile psychopathy are discussed.     

Treatment and psychopathy in forensic settings

People commonly question whether highly psychopathic offenders are treatable. Little scientific research has addressed this question despite key developments in the last 20 years in two relevant areas: reliable measurement of psychopathy, and effective treatments for reducing criminal and antisocial behavior in offenders. One obstacle to progress is confusion about defining psychopathy; a necessary preliminary step to advancing intervention. After outlining the principal definitional issues, we review past and recent research on psychopathy and treatment, concluding that a handful of newer, well-designed studies suggest grounds for optimism about psychopathy and treatability. Although psychopathy characteristics—along with other indices of criminal risk—signal responsivity challenges, well-conceived programs for higher risk offenders can reduce recidivism in highly psychopathic offenders and appear to do so by reducing dynamic risk factors. There are no clear indications yet of whether PCL-psychopathic offenders differ from other high-risk offenders in their ability to respond to such treatments. The questions of whether psychopathy itself responds to treatment, and if so, what forms such treatment might take have not yet been addressed. We conclude by suggesting that advances will come from the use of more divergent measures of psychopathy, and in particular, dynamic measures of psychopathy traits that will allow us to document whether change is occurring.     

Predictors of treatment outcome in dually-diagnosed antisocial youth: an initial study of forensic inpatients

The safe and effective management of adolescent offenders is a top priority for inpatient forensic programs. Treatment successes were examined for adolescent offenders on four parameters, specifically hospital course, level of improvement, time to discharge, and rapidity of improvement. Hospital course was predicted primarily by the breadth of polysubstance abuse with modest but independent contributions by psychopathic characteristics, and aggressive conduct-disorder symptoms. An important finding for treatment was that level of improvement at discharge was only marginally affected by psychopathic traits. In addition, rapidity of improvement was predicted only by decreased polysubstance abuse. Approximately one-fourth of the adolescent offenders experienced a substantial decrease in psychopathic characteristics. This finding was unexpected because the generic treatment program did not target the core elements of psychopathy. Even in the absence of nontreatment controls, this diminution of psychopathic traits in 25% of adolescent offenders raises important questions about the temporal stability of these traits and their potential amenability to generic interventions.     

Interaction between Prenatal Maternal Stress and Autonomic Arousal in Predicting Conduct Problems and Psychopathic Traits in Children

Evidence has suggested that neurobiological deficits combine with psychosocial risk factors to impact on the development of antisocial behavior. The current study concentrated on the interplay of prenatal maternal stress and autonomic arousal in predicting antisocial behavior and psychopathic traits. Prenatal maternal stress was assessed by caregiver’s retrospective report, and resting heart rate and respiratory sinus arrhythmia (RSA) were measured in 295 8- to 10-year-old children. Child and caregiver also reported on child’s antisocial behavior and psychopathic traits. Higher prenatal maternal stress was associated with higher caregiver-reported antisocial and psychopathy scores, even after the concurrent measure of social adversity was controlled for. As expected, low heart rate and high RSA were associated with high antisocial and psychopathic traits. More importantly, significant interaction effects were found; prenatal stress was positively associated with multiple dimensions of psychopathic traits only on the conditions of low arousal (e.g., low heart rate or high RSA). Findings provide further support for a biosocial perspective of antisocial and psychopathic traits, and illustrate the importance of integrating biological with psychosocial measures to fully understand the etiology of behavioral problems.     

Subtypes of adolescent offenders: affective traits and antisocial behavior patterns

Etiological models of life-course persistent offending often emphasize behavioral explanations. Suggestions that persistent offenders have psychopathy ignore the distinct non-behavioral features of the psychopathy disorder. Using a three-factor model of the PCL-YV and cluster analysis with 259 incarcerated adolescents, we identified four distinct juvenile subtypes on the basis of affective, interpersonal, and behavioral dimensions. Prospective and retrospective comparisons of antisocial behavior patterns found the cluster comprising all three psychopathy dimensions to be the most chronic and severe. Impulsive features alone were strongly associated with severe antisocial behaviors retrospectively, but not prospectively. Findings rebut the proposal that disruptive behavioral and impulsive symptoms can identify "fledgling psychopaths." Assessments that disregard callous-unemotional traits will likely result in high false positive rates among serious adolescent offenders. Implications for developmental models of chronic offending are discussed in light of the need for further follow-up into adulthood.     

An empirical investigation of psychopathy in a noninstitutionalized and noncriminal sample

This study examined the construct of psychopathy using the Psychopathy Checklist-Revised (PCL-R) in 54 participants from the general population. To obtain a sample of community participants with psychopathic characteristics, participants were recruited using advertisements for a "personality study" that incorporated the characteristics of psychopathy in a nonpejorative manner. The methodology successfully recruited community participants with moderately elevated PCL-R scores. Participants exhibited the personality features of psychopathy (Factor 1) to a greater extent than the behavioral features (Factor 2), which is consistent with the results obtained with the PCL-R normative samples. Roughly 40% of the sample reported no history of involvement with the criminal justice system, yet these participants exhibited moderately elevated PCL-R scores. Moreover, a sizeable portion of the noncriminal participants reported a substantial history of violent behavior. Comparisons of PCL-R scores between participants with and without a criminal history suggest that these two groups differ in ways unrelated to criminal justice system involvement.     

The validity of the Antisocial Process Screening Device as a self-report measure of psychopathy in adolescent offenders

There is a growing interest in the assessment of adolescent psychopathy to enable early treatment and intervention. Recently, a self-report measure has been developed to assess psychopathic traits in adolescents. The Antisocial Process Screening Device (APSD), a self-report measure of psychopathic traits, and the Psychopathy Checklist: Youth Version (PCL:YV), a clinical rating scale, were administered to a sample of 100 incarcerated male adolescent offenders to assess the concurrent validity of the APSD. Results indicated that the APSD had limited concurrent validity with respect to the PCL:YV and that there appears to be a method effect in the measurement of psychopathy. Thus, it appears the APSD did not assess psychopathy in a manner parallel to that of the PCL:YV.     

Child and adolescent psychopathy: Assessment issues and treatment needs

The identification of psychopathic traits in childhood and adolescence is a topic of growing interest for scientific research. The development of models to predict violent behavior, together with efficient preventive and therapeutic programs, is a major goal when assessing youths with psychopathic traits. This paper focuses on the construct of child and adolescent psychopathy, while approaching historical and conceptual issues. By discussing the “state of the art” of the construct, we will analyze different instruments to assess psychopathy in children and adolescents, as well as the available treatment modalities. Finally, we will present possible lines for research and clinical intervention according to an evolutionary approach to anger and antisocial behavior.     

精神病态暴力犯执行功能的缺陷*

为了解精神病态罪犯可能存在的执行功能缺陷及其是否受冲动性影响,研究采用精神病态检核表（PCL-R）筛选出30名精神病态组被试和30名非精神病态组被试,通过爱荷华赌博任务（IGT）和河内塔任务（TOH）对两组被试执行功能的特点进行分析,并结合冲动性量表（BIS-11）对其冲动性进行测量。研究发现精神病态组的冲动性显著高于控制组;精神病态组选择高风险的不利牌显著多于对照组,即对惩罚不敏感;精神病态组在河内塔任务中的错误次数及所消耗时间都显著高于控制组;冲动性水平与两任务得分均无显著相关。结果表明,精神病态暴力犯在与前额叶相关的执行功能上存在缺陷,并与个体的高冲动性无关。     

Psychopathy and Anxiety in Children and Adolescents: New Insights on Developmental Pathways to Offending

This study examined the relation between psychopathy and anxiety in 130 juvenile offenders. Adolescents were administered three psychopathy scales (PCL-YV, APSD, and SRP-II), a measure of psychopathology (APS), and subsequently followed prospectively in the community for three years in order to track recidivism. Three mediational models were tested to determine whether psychopathy mediates the relation between anxiety (trait anxiety, fearlessness, and trauma) and future offending. Findings indicated that psychopathy mediated the relation between two types of anxiety (trait anxiety and fearlessness) and recidivism when using the PCL-YV as an index for psychopathy. These influences were not supported when using self-report measures of psychopathy (APSD and SRP-II) and the meditational models did not apply to the anxiety subtype of trauma for any of the psychopathy measures. The PCL-YV mediational models provide new insights on the relation between psychopathy anxiety and offending. Specifically, pathways from fearlessness to psychopathy and later offending were in the expected direction. Surprisingly, higher levels of trait anxiety were linked with higher levels of psychopathy and subsequent offending. This developmental difference is in contrast with theory and the adult literature on this topic. The results from the current study suggest that both fear and anxiety may be important considerations in treatment planning for the reduction of adolescent offending.     

Psychopathic Traits in Youth: Is There Evidence for Primary and Secondary Subtypes?

The current study employed model-based cluster analysis in a sample of male adolescent offenders (n = 94) to examine subtypes based on psychopathic traits and anxiety. Using the Psychopathy Checklist: Youth Version (PCL:YV; Forth et al. 2003) and the self-report Antisocial Process Screening Device (APSD; Caputo et al. 1999), analyses identified three clusters in males that varied in the severity of psychopathic traits (low, moderate, and high) and anxiety. The high psychopathic group exhibited more negative personality traits and was judged to be at greater risk for dangerousness whereas the low psychopathic group exhibited more positive personality traits and was judged to be at lower risk for dangerousness. Implications regarding potential developmental differences between adolescent and adult psychopathy, as well as treatment considerations are discussed.
