From prediction to explanation: Is the relationship between youth psychopathy traits and continued offending in adulthood mediated by social environment?

Studies that focus on whether psychopathy statistically predicts reoffending are not informative of the process that connects the putative cause (psychopathy) to the expected outcome (offending). Understanding the causal mechanisms responsible for the relationship between psychopathy and offending has received minimal empirical attention even though fourth-generation risk assessment protocols and treatment strategies regularly require a specific focus on psychopathy. Theory can help guide an improved understanding of the causal mechanisms underlying the relationship between psychopathy and offending. Cumulative disadvantage theories anticipate that the relationship between psychopathy and reoffending is mediated by a person's social environment. Propensity theories anticipate that psychopathy is a common cause of both a person's negative social environment and reoffending. These two theoretical perspectives were compared using longitudinal data covering the transition from adolescence to adulthood among 490 male and female participants from the Incarcerated Serious and Violent Young Offender Study. Psychopathy was measured in adolescence using the Psychopathy Checklist: Youth Version. Social environment was measured in adulthood using an informal social control scale from the Community Risk Needs Assessment. Conviction frequency was measured over a 3-year period after the Community Risk Needs Assessment rating. Bias-corrected bootstrapped confidence intervals indicated that informal social control partially mediated the relationship between Psychopathy Checklist: Youth Version scores and conviction frequency. The mediating effect was robust to unobserved confounders. Findings supported the philosophy of risk management and intervention strategies that target a person's social environment when aiming to reduce reoffending for persons with psychopathy traits.

BRAIN IMAGING OF PSYCHOPATHY: A NARRATIVE LITERATURE REVIEW

The general definition of psychopathic is an individual who focuses on self-perspective, is feelingless, without compassion, lacks empathy, lacks/disloyalty, and lacks the ability to form close relationships (less intimacy). Psychopathy is also known as psychopathic, antisocial, disocial, and sociopathic personality disorder. In Indonesia, clinical diagnosis guidelines for psychopathic individuals still refer to Dissocial Personality Disorder according to the Guidelines for Classification and Diagnosis of Mental Disorders Edition III (PPDGJ-III), coupled with other commonly used supporting examinations, namely the MMPI (Minnesota Multiphasic Personality Inventory), LSRP (Levensone Self-Report Psychopathy Scales), PCL:SV (Psychopathy Checklist: Screening Version). This Narrative Literature Review aims to summarize findings about brain imaging in Psychopath. As for psychopathic-related brain imaging, namely aberrant brain activity was found in the prefrontal area, temporal cortex, limbic (amygdala- hippocampus complex), striatum, corpus callosum, and insular. These findings hope to be able to explain the basic etiological of deviant behavior in psychopathic perpetrators. Thus, psychopathic neuroanatomy is a research area that has the potential to contribute as a preventive and curative measure of psychopathy on a scientific basis.

Evaluator Disagreement about the Association between Psychopathy Checklist-Revised Scores and Risk for Future Sexual Violence

It is common for forensic evaluators to use assessment instruments in risk assessment evaluations. This study examines whether different evaluators use instrument results the same way when coming to conclusions about risk for sexual recidivism in Sexually Violent Predator (SVP) evaluations. Three evaluators who each used both the Static-99R and Psychopathy Checklist-Revised in more than 60 SVP evaluations (Total N = 338) provided data for the study. There were clear evaluator differences in how instrument scores were associated with risk opinions. For one evaluator, multiple regression results revealed that PCL-R Facet 2 (Affective) and Facet 3 (Lifestyle) scores were the only statistically significant predictors of risk. In other words, this evaluator’s risk opinions were more clearly associated with scores on a psychopathy measure (PCL-R) than scores on a measure specifically designed to assess risk (Static-99R). For another evaluator, only Static-99R scores were independent predictors of risk. For the final evaluator, Static-99R scores and, to a lesser extent, PCL-R Facet 2 scores were independent predictors of risk. These findings add to the growing body of research suggesting that forensic evaluation results can depend, to a non-trivial extent, on the specific evaluator conducting the evaluation.

Predictive validity of the Psychopathy Checklist: Screening Version (PCL:SV) in a sample of New Zealand Māori and European male prisoners.

Numerous studies have investigated the predictive validity of the Hare Psychopathy Checklist (PCL), but the majority have used samples from North America. The PCL may inform important decisions about people's futures; recognition has been growing of the importance of ensuring that its psychometric properties are established in each jurisdiction where it is used, especially for Indigenous and non-European populations. The present study examined the predictive properties of the Hare Psychopathy Checklist: Screening Version (PCL:SV; Hart et al., 1995) in 371 New Zealand (NZ) male prisoners, including NZ European and NZ Māori subsamples. Discrimination analyses showed that PCL:SV total scores had moderate predictive accuracy for any new conviction within 5 years of release; no significant differences were detected for Māori versus NZ European on this outcome. PCL:SV Factor 2 (Lifestyle/Antisocial) scores were moderately predictive of violent recidivism within 5 years of release. In a second, independent sample of male prisoners (n = 102), both PCL:SV total and Factor 2 scores showed moderate predictive accuracy for serious institutional violence. Additionally, PCL:SV Facets 1 (Interpersonal) and 2 (Affective) scores were uniquely associated with time to sexual and violent recidivism, respectively. Understanding the predictive performance of clinical risk measures across diverse ethnic groups is an important step toward identifying and addressing ethnic disparities in criminal justice outcomes.

Psychopathy and Gender in Three Faces of Homicide

ABSTRACT Few existing studies have explored the relationship between facet-levels of psychopathy and different types of homicide. This study analyzed Korean homicide offenders’ psychopathic traits that were assessed by the Psychopathy Checklist-Revised (PCL-R) and compared family homicide offenders to those who killed complete strangers, and to those who killed nonfamily acquaintance victims. The study used the four psychopathy facet scores, age, education, and gender as predictors to postdict the three types of homicide. Multinomial logistic regression as well as Somer’s d tests revealed that psychopathic traits differentially contributed to the different forms of deadly violence. Compared to family homicide, stranger homicide scored higher on facet 2 (affective), facet 3 (lifestyle), and facet 4 (antisocial), but lower on facet 1 (interpersonal). In the similar sense, nonfamily homicide scored higher on facets 3 and 4, but lower on facet 1, when compared to family homicide. Family homicide offenders’ higher deficit in interpersonal traits (higher scores on facet 1) has been discussed, but merits further analysis. In addition, homicides by men tended to be extrafamilial, whereas killings by women were more likely to be intrafamilial. The study suggests interesting insights on differences in psychopathy and gender in the typology of homicide.

Risk for Violent and IPV Recidivism Among Incarcerated Men With a History of IPV Perpetration: An Examination of the Predictive Validity of the ODARA, DVRAG, and PCL-R

Using a hybrid prospective-retrospective study design, we examined the predictive validity of the Ontario Domestic Assault Risk Assessment (ODARA), Domestic Violence Risk Appraisal Guide (DVRAG), and the Psychopathy Checklist–Revised (PCL-R) in an incarcerated sample of 94 Canadian adult men with a history of intimate partner violence (IPV) referred for treatment. The sample was followed for an average of 3.6 years following release, yielding base rates of 23.4% and 12.8% for violent and IPV recidivism, respectively. Analyses revealed that the ODARA and DVRAG displayed high inter-rater reliability and that the two measures along with Factor 1 of the PCL-R generated the largest area under the curve (AUC) for IPV recidivism (AUC = .71, .71, and .69, respectively). Predictive validity of the three measures was maintained even after accounting for treatment exposure. Although promising, clinical implications of administering the ODARA and DVRAG to incarcerated men with a history of IPV are discussed.

Psychopathy traits explain variance shared between features of substance use disorders and violence.

There is a substantial research literature on identifying risk and protective factors for violence perpetration. Substance use disorders have long been identified as constituting a significant predictor of violent behaviour. Psychopathy traits have also been similarly recognised, but inter-relationships between psychopathy traits, features of substance use disorders and violence have been little explored. To determine the degree to which shared variance between substance dependence symptoms and violence, as indicated by criminal charges for violent offences, among jailed men can be explained by psychopathy traits. Features of dependence on substances in three drug classes (alcohol, cannabis and cocaine) were assessed in a sample of 682 men in a county jail awaiting trial on criminal charges, many for violent offences. Statistical comparisons of zero-order and partial correlations tested whether accounting for psychopathy total and facet scores, assessed by the Psychopathy Checklist-Revised (PCL-R), affected associations between substance dependence symptoms and violent charges. Total PCL-R scores accounted for a significant proportion of the shared variance between the history of criminal charges for violence offences and lifetime substance dependence symptoms in all three drug classes. At the facet level, controlling for ratings on the interpersonal and modified antisocial facets reduced the association between criminal charges for violent offences and symptoms of cocaine dependence; controlling for ratings on a modified antisocial facetalso attenuated links between alcohol and cannabis dependence symptoms and history of charges for violent offences. These findings build on the sparse literature to date on the role of psychopathy traits on relationships between features of substance use disorders and violence. Given that the observed connection between substance dependence symptoms and charges for violent offences is partly accounted for by individual differences in psychopathy traits, it follows that effective treatment for those traits may be useful, perhaps essential to reducing links between features of some substance use disorders and violent offending.

Perception of emotional facial expressions in aggression and psychopathy.

Altered affective state recognition is assumed to be a root cause of aggressive behavior, a hallmark of psychopathologies such as psychopathy and antisocial personality disorder. However, the two most influential models make markedly different predictions regarding the underlying mechanism. According to the integrated emotion system theory (IES), aggression reflects impaired processing of social distress cues such as fearful faces. In contrast, the hostile attribution bias (HAB) model explains aggression with a bias to interpret ambiguous expressions as angry. In a set of four experiments, we measured processing of fearful and angry facial expressions (compared to neutral and other expressions) in a sample of 65 male imprisoned violent offenders rated using the Hare Psychopathy Checklist-Revised (PCL-R, Hare, R. D. (1991). The psychopathy checklist-revised. Toronto, ON: Multi-Health Systems) and in 60 age-matched control participants. There was no evidence for a fear deficit in violent offenders or for an association of psychopathy or aggression with impaired processing of fearful faces. Similarly, there was no evidence for a perceptual bias for angry faces linked to psychopathy or aggression. However, using highly ambiguous stimuli and requiring explicit labeling of emotions, violent offenders showed a categorization bias for anger and this anger bias correlated with self-reported trait aggression (but not with psychopathy). These results add to a growing literature casting doubt on the notion that fear processing is impaired in aggressive individuals and in psychopathy and provide support for the idea that aggression is related to a hostile attribution bias that emerges from later cognitive, post-perceptual processing stages.

Adolescents with Elevated Psychopathic Traits are Associated with an Increased Risk for Premature Mortality.

The mortality rate among adolescents has been steadily increasing in recent years. Researchers have previously identified forms of externalizing psychopathology measured during adolescence associated with an increased risk for premature mortality, including attention-deficit/hyperactivity disorder (ADHD), substance use disorders (SUDs), oppositional defiant disorder (ODD), and conduct disorder (CD). The current study investigated whether additional personality traits (i.e., adolescent psychopathic traits, assessed via the Hare Psychopathy Checklist: Youth Version [PCL:YV]) were also associated with premature mortality risk among maximum-security incarcerated adolescents (N = 332). During a follow-up period ranging from 10 to 14 years, premature mortality was observed in n = 33 participants (9.94%), a mortality rate nearly ten times higher than population norms. We observed that adolescents scoring the highest on PCL:YV total scores exhibited significantly higher rates of premature mortality compared to adolescents scoring lower on PCL:YV total scores via Fisher's exact tests. Additionally, through univariate Cox proportional hazard regression analyses, PCL:YV total, Factor 2 (measuring lifestyle/behavioral and antisocial/developmental psychopathic traits), Facet 1 (measuring interpersonal psychopathic traits), and Facet 3 (measuring lifestyle/behavioral psychopathic traits) scores were associated with faster time to premature mortality. In supplemental analyses performed, we observed that adolescents meeting criteria for externalizing psychopathology (i.e., ADHD, SUDs, ODD, and CD) did not exhibit higher rates of premature mortality compared to control participants. The current study therefore identifies additional maladaptive personality traits to consider in relation to premature mortality risk (i.e., psychopathic traits) among a high-risk sample of incarcerated adolescents.

Unveiling covert psychopathy: a case report utilizing the Psychopathy Checklist-Revised scale in the forensic psychiatric setting

This case report explores the diagnostic complexities and treatment challenges associated with psychopathy and antisocial personality disorder (ASPD) in a forensic psychiatric setting. Utilizing the Psychopathy Checklist-Revised (PCL-R) scale, we assessed a 29-year-old male previously detained for two attempted murders and investigated for insulting a public official. Despite a history of mood and psychotic symptoms, previous evaluations failed to identify underlying psychopathic traits. Our assessment revealed a PCL-R score of 33/40, indicating a clear picture of psychopathy. The subject exhibited aggressive and violent behaviors from childhood, including cruelty to animals and reckless actions. Diagnoses over time included attention deficit/hyperactivity disorder, bipolar disorder, and substance use disorders, reflecting significant diagnostic heterogeneity. The case underscores the importance of comprehensive psychopathy assessments in forensic contexts, particularly when previous diagnoses and treatments have been inconsistent. Our findings highlight the potential of the PCL-R scale as a valuable tool for identifying covert psychopathic traits, which are often underestimated. This study calls for further research into the diagnostic and therapeutic approaches for psychopathy and ASPD, emphasizing the need for tailored interventions in correctional institutions to mitigate the risk of recidivism.

The Effects of Psychopathy Facets on Treatment Involvement.

The current study explored the relations between patient characteristics and psychopathic traits in predicting treatment involvement. We rated treatment involvement using detailed archival clinical files of 218 individuals committed to the Massachusetts Treatment Center (MTC). Psychopathy Checklist-Revised (PCL-R) scores had been rated from a previous study on the same sample. Overall, PCL-R Facets 2 and 4 significantly predicted decreases in treatment involvement, suggesting the characteristics associated with these facets have the most disruptive effects on treatment involvement. Exploratory analyses were also conducted assessing the relations between the PCL-R facets and the individual treatment involvement components. Whereas Facet 2 significantly predicted lower levels in all three individual treatment involvement components, Facet 4 only significantly predicted lower levels in two, highlighting the differentiating effects of these facets. Identifying the components that have either positive or negative effects on treatment involvement can allow clinicians to tailor treatments to optimize treatment involvement and outcome.

Do risk measure scores and diagnoses predict evaluator opinions in sexually violent predator cases? It depends on the evaluator.

Field research increasingly reveals that forensic evaluators are not interchangeable. Instead, they tend to differ in their patterns of forensic opinions, in ways that likely reflect something about themselves, not just the persons evaluated. This study used data from sexually violent predator (SVP) evaluations to examine whether evaluator differences in making intermediate decisions (e.g., instrument scoring, assigning diagnoses) might explain their different patterns of final opinions. Although this study was generally exploratory and not strongly hypothesis driven, we expected that there might be evidence for a simple form of bias in which some evaluators would be more likely than others to consistently "find" indications of SVP status (i.e., consistently assigning higher risk scores and more SVP-relevant diagnoses) and, therefore, be more likely to find behavioral abnormality, the legal construct qualifying someone for commitment as an SVP. The study used data from 745 SVP evaluations conducted by 10 different evaluators who were assigned cases from the same referral stream. Potential evaluator difference variables included behavioral abnormality opinions, paraphilia and antisocial personality disorder diagnoses, and Psychopathy Checklist-Revised and Static-99 scores. Evaluator differences explained a statistically significant (p < .001) amount of variance in behavioral abnormality opinions (17%), paraphilia diagnoses (7%), and Psychopathy Checklist-Revised scores (16%). Contrary to our expectation of a simple tendency for some evaluators to find all indicators of SVP status more often than others, evaluators differed in the ways that underlying diagnoses and scores corresponded with their conclusions. The overall pattern was one in which different evaluators appeared to base their final opinions on different factors. Findings reveal further evidence of substantial forensic evaluator differences in patterns of assigning instrument scores and reaching forensic conclusions. But these findings are the first to also reveal wide variability in their patterns of reaching forensic conclusions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Psychopathic Traits in Adult versus Adolescent Males: Measurement Invariance across the PCL-R and PCL:YV.

Both the Psychopathy Checklist-Revised (PCL-R) and the Psychopathy Checklist: Youth Version (PCL:YV), respectively, are established instruments for assessment of psychopathy and development of psychopathic propensity. To reliably compare scores from both instruments, measurement invariance must be established. The current study involved a combined sample of 1091 male participants (adults = 813; adolescents = 278) from correctional facilities in New Mexico. An exploratory structural equation modeling (ESEM) framework was used to test for measurement invariance. The four-factor ESEM model demonstrated good fit for the combined and individual samples. Results from the multiple group ESEM provide evidence for generally strong invariance, with equivalent factor loadings and thresholds. Adolescents exhibited decreased latent interpersonal traits but increased latent features on other PCL factors (affective, lifestyle, and antisocial) compared to adults. Findings suggest that the four-factor model and the measurement of psychopathic traits remain consistent across age groups. Implications of the findings within research and clinical contexts are discussed.

Psychopathy, psychological distress, and treatment history among perpetrators of intimate partner femicide, homicide, and other violent crimes in Buenos Aires, Argentina

Intimate partner femicide—the killing of women based on their gender by their former or current partners—is a global long-standing manifestation of violence against women. Despite the enactment of femicide-specific laws in Latin America, femicide rates have remained relatively constant throughout the last decade. Often perpetrators are pathologized as suffering from mental illness, yet the data on their mental health status is still relatively unknown. Thus, more research is needed to understand the extent of poor mental health among these individuals. The purpose of this study was to compare levels of psychopathy, psychological distress, and treatment history among an all-male sample of intimate partner femicide perpetrators, male-male homicide perpetrators, and offenders convicted of other violent crimes in Buenos Aires, Argentina. This study utilized a cross-sectional survey based on data derived from a two-stage sampling strategy. The questionnaire included two standardized instruments for the measurement of psychopathy (revised Psychopathy checklist and the Levenson Self-Report Psychopathy scale) and one for general distress (Spanish version of 12-item General Health Questionnaire). The final sample included 205 prisoners including 68 intimate partner femicide perpetrators, 73 homicide perpetrators, and 64 individuals convicted of other violent crimes. There were no significant differences across these groups based on their socio-demographic characteristics. Participants did not differ in terms of their psychopathology; however, femicide perpetrators were statistically more likely to experience psychological distress. In addition, femicide perpetrators self-reported more prior episodes of mental and substance use treatments. The findings of increased psychological distress and prior mental health and substance use treatment among femicide perpetrators suggest that there may be missed opportunities for femicide prevention within the public health subspecialties of mental health and substance use disorders. This study suggests that femicide perpetrators likely require distinctive interventions, including self-assessments and harm mitigation tactics, to prevent their potential for femicide perpetration.

EFFECTS OF FAMILY DYNAMICS ON PSYCHOPATHIC TRAITS AND CRIMINAL TENDENCIES AMONG NON-CRIMINAL PEOPLE

The present study investigates the impact of family dynamics on the development of psychopathic traits in non-criminal populations. Utilizing a sample size of 200 participants, the study employs the Hare Psychopathy Checklist-Revised (PCL-R) to quantify psychopathic traits and examine the association with specific family patterns. The results indicate that poor parental supervision, inconsistent discipline, and high family conflict are significantly correlated with higher levels of psychopathic traits. Quantitative analysis reveals that individuals with high scores on the PCL-R are more likely to report negative family dynamics. Qualitative data from interviews and observations support these findings, highlighting the critical role of early family interactions in shaping psychological development. The study underscores the importance of early identification and family-based interventions to mitigate the development of psychopathic traits. These findings contribute to the broader understanding of psychopathy and offer valuable insights for developing targeted preventive strategies.

In the I of the beholder: an attempt to capture the implicit self-concept regarding psychopathy.

This article explores the implicit self-concept pertaining to psychopathy. Two online studies showed inconsistent results, with Study 1 (n = 243) suggesting that psychopathy is linked to an implicit self-concept marked by low empathy and Study 2 (n = 230) implying no such relationship. In a sample of offenders and community controls (Study 3a, n = 166), higher scores on the Psychopathy Checklist-Revised (PCL-R) were related to an implicit self-concept of being less rather than more antisocial, and the implicit self-concept showed incremental validity compared to the explicit self-concept. The retesting of an offender subsample (Study 3b, n = 47) yielded no evidence for temporal stability or convergent validity. The implicit self-concept of highly psychopathic individuals thus appears to vary, depending on the social context. Future studies should replicate these results in different samples, using additional external correlates.

The Utility of Expert-Rated and Self-Report Assessments of Youth Psychopathic Traits for Predicting Felony Recidivism Among Formerly Incarcerated Youth

Psychopathic traits assessed with expert-rated instruments are well-established predictors for both general and violent felony recidivism outcomes in adjudicated youth. However, it is not clear whether self-report assessments of psychopathic traits show similar predictive value. The current study evaluated both expert-rated (i.e., the Hare Psychopathy Checklist: Youth Version [PCL:YV]) and self-report measures (i.e., the Childhood Psychopathy Scale, Inventory of Callous Unemotional Traits, Antisocial Process Screening Device, and the Youth Psychopathic Traits Inventory) assessing youth psychopathic traits for predicting general and violent felony recidivism among formerly incarcerated high-risk male adolescents ( n = 275). Scores on both expert-rated and self-report instruments were significantly associated with a shorter time to felony rearrest into early adulthood (with an average follow-up window of 11 years). However, the expert-rated PCL:YV, but not self-report measures, provided significant utility for predicting violent felony arrest. These results suggest that in general, youth psychopathic traits, regardless of the specific instrument used, are predictors of general felony rearrest outcomes, while the expert-rated PCL:YV alone provides utility for predicting the most severe crimes (i.e., violent felonies). The strengths and limitations of the assessment modalities are discussed.

Emotion Regulation Difficulties and Callous-Unemotional Traits: The Role of Guilt Across Samples of Incarcerated Male Adult Offenders

ABSTRACT The study aimed to: (1) analyze differences between psychopathic and non-psychopathic offenders in terms of difficulties in emotion regulation and callous-unemotional traits, (2) investigate the association between difficulties in emotion regulation and callous-unemotional traits among psychopathic and non-psychopathic offenders, and (3) examine the mediation role of guilt in the relationship between difficulties in emotion regulation and callous-unemotional traits among non-psychopathic offenders, controlling for the level of desirable responses. The participants were 191 incarcerated male adult offenders serving their sentences in closed and semi-open custody. The incarcerated offenders participated in a semi-structured interview and completed self-report measures of emotion dysregulation, guilt, callous-unemotional traits, and social desirability. According to the results on the Hare Psychopathy Checklist-Revised, 60 (27.9%) participants were included in the psychopathic group, while 131 (60.9%) were non-psychopathic. The results showed a positive relationship between difficulties in emotion regulation, callousness, and psychopathy. The multiple regression analysis indicated that guilt contributed to the variance of callousness. Guilt was a mediator in the relationship between difficulties in emotion regulation and callousness among the group of non-psychopathic incarcerated offenders. The current study highlighted the importance of guilt as an adaptive moral emotion useful in the treatment of several psychological problems among male offenders.

Adverse childhood events and self-harming behaviours among individuals in Ontario forensic system: the mediating role of psychopathy

BackgroundAdverse childhood events (ACEs), psychopathy, and self-harming behaviours are prevalent among individuals in the forensic psychiatry system. While existing literature suggests that ACEs, self-harm, and psychopathy are interrelated, little is known about the interplay of psychopathic traits in this relationship. The present study aimed to determine the mediating role of psychopathy in the relationship between ACEs and self-harming behaviours in forensic patients.MethodsThis was a retrospective study of patients under the Ontario Review Board (ORB) between 2014 and 2015. In the analysis, we included patients with complete data on ACEs, self-harming behaviours, and a Psychopathy Checklist-Revised (PCL-R) score - a measure of psychopathic traits and their severity conducted during the reporting period. Mediation analysis was based on the Baron and Kenny approach, and sensitivity analysis was performed based on the types of ACEs.Results​​​The sample population (n = 593) was made up of adults, with a mean age of 41.21 (± 12.35) years and were predominantly males (92.37%). While there was a partial mediating effect of psychopathy on the relationship between ACEs and incidents of self-harming behaviours in the past year, the mediation was complete in the relationship between ACEs and a lifetime history of self-harming behaviours. Following sensitivity analysis based on the types of ACE, the mediating effects were more attributed to specific ACEs, especially having experienced child abuse or having an incarcerated household member before 18 years.ConclusionAmong forensic patients in Ontario, psychopathy mediates​ ​the relationship between experiencing ACEs and engaging in self-harming behaviours. Effective intervention to mitigate self-harming behaviours in this population should consider the potential role of psychopathy, especially among individuals who have experienced ACEs involving a history of child abuse and a family who was incarcerated.

Therapeutic and risk relevance of psychopathy and general criminal attitude change in an institutional sexual offense treatment program.

We examined the interrelationships between psychopathy, changes in general criminal attitudes, and community recidivism in a sample of 212 men who attended an institutional sexual offense treatment program (SOTP) and were followed for an average of 12.73years post-release. The men completed a self-report measure of general criminal attitudes, the Criminal Sentiments Scale, as part of routine SOTP service delivery, Psychopathy Checklist-Revised (PCL-R) ratings were completed via file review, and recidivism data were obtained from official criminal records. Criminal attitude endorsement and criminal attitude change had clinically meaningful, but differential, associations with the antisocial and interpersonal features of psychopathy. Further, positive changes in criminal attitudes-particularly tolerance of law violations (i.e., rationalizations for criminal behavior)-were significantly predictive of reductions in community violent and general recidivism after controlling for PCL-R score. Results demonstrate that general criminal attitude change has risk relevance in the treatment of high psychopathy persons with sexual offense histories.
