Studies have described measures associated with assault in the community, but few have identified measures associated with assault in prison or prison psychiatric treatment. In this study, prison assault histories and assaults while in prison psychiatric treatment for 222 randomly selected male inmates were evaluated. Using record reviews, interviews, neuropsychological, Rorschach, and psychopathy measures, risk factors for assault in prison and in prison psychiatric treatment were identified. Youth Authority placement, inhalant use, antisocial lifestyle, neurological injury, neuropsychological impairment, and higher PCL-R Factor II ratings were associated with assault in prison. Absence of major mental disorder, neurological impairment, or psychotic thinking, but presence of psychopathy was associated with assault in prison psychiatric treatment. In identifying risk for violence, the importance of (1) the context in which violence occurs; (2) the need for clear admission criteria for prison psychiatric treatment; and (3) the need to develop risk assessments that are specific to prison environments are emphasized.

This study used confirmatory factor analysis to compare alternative models of the structure of posttraumatic distress symptoms as measured by the Posttraumatic Stress Disorder Checklist--Civilian version (PCL-C; F. W. Weathers, B. T. Litz, D. S. Herman, J. A. Huska, & T. M. Keane, 1993). Data were derived from English- (N = 299) and Spanish-speaking (N = 120) samples of young adult survivors of community violence recruited following hospitalization for physical injuries. The best fit to the data was a four-factor model measuring correlated dimensions of reexperiencing, avoidance, emotional numbing, and hyperarousal. English- and Spanish-language versions of the PCL-C showed general measurement equivalence.

This study examined the predictive validity of the Hare Psychopathy Checklist: Youth Version (PCL:YV) from adolescence to early adulthood. The authors coded the PCL:YV using file information and collected criminal record information over a 10-year follow-up period on 157 boys, ages 12 through 18, referred to Youth Forensic Psychiatric Services for assessment in 1986. The risk for violence into early adulthood was greater among those with high PCL:YV scores than among those with low scores, even after controlling for conduct disorder, age at first offence, and history of violent and nonviolent offending. These results indicate that the PCL:YV provides meaningful information about young offenders' risk for violence into early adulthood. Clinical implications are discussed, with reference to pertinent ethical issues.

A survey of clinical views suggests that the significance of antisocial and socially deviant behavior in the diagnosis of psychopathic personality disorder is unclear. To investigate this issue, we evaluated Psychopathy Checklist-Revised ratings (PCL-R; Hare, 1991) using structural equation modeling. One model, referred to as the measurement model, included PCL-R ratings related to antisocial behavior as primary symptoms of psychopathy; a second, referred to as the causal model, included the same PCL-R ratings as secondary symptoms or consequences. Compared to the measurement models, the causal model included more PCL-R items, was more parsimonious, and had equal or superior fit indices. These findings suggest that antisocial behavior is best viewed as a secondary symptom or consequence of psychopathy, In addition, the findings have important implications for future research and clinical-forensic practice, especially concerning the assessment of risk for criminality and violence.

Violence risk assessment constitutes a major concern in forensic psychiatry, psychology and related fields. Numerous instruments like the Hare Psychopathy Checklist (PCL-R, Hare, 1991) and the Violence Risk Appraisal Guide (VRAG) have been developed in the aim of improving precision in the prediction of violence. This study assesses the reliability index of the HCR-20 Violence Risk Assessment Scheme and evaluates its relationship with the PCL-R the Buss and Perry's self-report Aggression Questionnaire (AQ) and the type of offenses officially registered. All participants (n=86) are male adult offenders detained in a Belgian high-security forensic hospital. The mean IQ and age were respectively, 81,03 and 36,71. Items common to these instruments were omitted in order to avoid a circular effect. Results showed that the HCR-20 was significantly related to the PCL-R: the historical factor was strongly correlated to the PCL-R factor 2 while the clinical factor was strongly correlated to the PCL-R factor 1. The HCR-20 was significantly related to the AQ: the historical factor was strongly correlated to the AQ Physical Aggression factor and to the Anger factor. As regards to the HCR-20 relations with offenses, its Historical factor was related to both violent (assault and battery, robbery) and non-violent offenses (drug offenses, theft). Finally, the HCR-20 was also positively related to "instrumental" and rather premeditated homicide but negatively related to psychotic homicide. The overall findings are congruent with -published data on the convergent validity of the HCR-20.

The present study investigated 154 consecutive admissions to the Regional Treatment Center (Ontario) Sex Offender Treatment Program with reference to psychopathy and outcome. Ratings of treatment behavior, as well as clinical judgments as to whether risk was reduced, were coded based on treatment reports. With reference to Psychopathy Checklist-revised (PCL-R) scores, survival analyses indicated that high scorers recidivated at significantly higher rates than low scorers. However, offenders who received high PCL-R scores and lower scores on measures of treatment behavior recidivated at the same rate as low scorers on the PCL-R. Furthermore, among high PCL-R offenders, those rated as lower risk at post treatment in fact reoffended at a lower rate than those whose risk was rated as unchanged, although this difference failed to reach significance. Findings are discussed in light of the clinical and research literature.

This study evaluated the structural reliability, construct-related validity, and cultural validity generalization of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a sample of more than 560 male and female Swedish forensic psychiatric treatment patients, forensic evaluation patients, and criminal offenders. Structural reliability was excellent for most indices. PCL:SV scores were higher for males than females for total and Part 1 scores (interpersonal/affective features) but not for Part 2 (behavioral features). With some exceptions, PCL:SV scores were meaningfully related to aggression to others, a measure of risk for violence, substance use problems, personality disorder (positive), and psychosis (negative). Correlations between PCL:SV and aggression were larger for females than males, although the difference was smaller when personality disorder was held constant. The structural reliability and pattern of validity coefficients were comparable in these Swedish samples to other non-North American samples. Implications for the cross-cultural manifestation and correlates of psychopathy are discussed.

This study explores the performance of 132 female maximum-security inmates on the Psychopathy Checklist-Revised (PCL-R) and the HCR-20 (Historical, Clinical, and Risk Management Scheme) to examine the concordance between these two risk assessment instruments, and to assess their potential usefulness in determining level of risk for violent behavior and other forms of criminality. The two instruments demonstrated consistent and highly significant correlations across total scores, factor scores, and subscale scores. When the two instruments were entered into a multiple regression analysis to predict violent and non-violent crime, the HCR-20 did not add to the variance explained by the PCL-R. These results confirm earlier research that suggests that there is little or no difference between these two risk assessment instruments in their relationship to community or institutional violence. Further, Receiver Operating Characteristics (ROC) analyses show that both instruments demonstrated an inverse ability to predict convictions for murder, a close to chance ability to predict violent crime, but a shared ability to predict property and minor crime. Broadly, these results suggest that psychopathic women are involved in chronic patterns of non-violent criminality, while women charged and convicted of murder generally do not have elevated scores on the PCL-R or HCR-20. The relevance of these findings to rehabilitation and treatment is discussed.

This study examined the institutional outcomes (12 weeks post-admission) of 134 male patients with DSM-IV schizophrenia assessed using the Psychopathy Checklist: Screening Version (PCL: SV) in a medium secure unit in the UK. High psychopathy scorers (HP) were more likely to be violent, non-compliant with programmes, engage in substance misuse violations, have criminal attitudes/peers and have low levels of insight into risk and violence. Psychopathy was also a modest predictor of institutional outcome in these domains.

Despite a flurry of studies examining psychopathy in women, and the recent release of the second version of the Hare Psychopathy Checklist--Revised manual, there is still little consensus whether the lateral extension of the current conceptualization of psychopathy to women is appropriate. In particular, very little agreement exists concerning the clinical utility of the Hare psychopathy measures to assess women's risk of future offending and violence. This article presents a comprehensive review of studies of the association between psychopathy, antisocial behavior, and violence, in diverse samples of women, and looks at similarities and differences between these constructs in males and females. Findings from inmates and offenders, civil and forensic psychiatric patients, substance abusers, and community samples indicate a consistently lower base rate of psychopathy among women than among men. With some exceptions, correlates of psychopathy in women relevant to risk assessments for crime and violence tend to be modest and significant, generally mirroring what we see in men. Clinicians and policy makers charged with the care and management of women at risk for criminal offending and violence are likely to find the PCL-R and PCL:SV have clinical utility; however, cautious application is called for and ongoing research is required.
