Recidivism risk assessment in sex offenders

Violent behaviour risk assessment is one of the most relevant research areas in current Psychology of Crime. Various scales for violence risk assessment have recently been developed from research about crime careers and risk factors. One of these instruments is the Sexual Violence Risk Assessment-20 (SVR-20), translated and adapted to Spanish by the Group of Advanced Studies in Violence of the University of Barcelona. The goal of this study is to verify the predictive capacity of the SVR-20 to predict sexual violence recidivism in a Spanish sample of sexual offender inmates. The method used was a retrospective study based in 163 sexual offender files and a 4-year time lag. The data were analysed with the logistic regression technique. Of the sample, 79.9% non-recidivist individuals were correctly classified, and 70.8% recidivist individuals. The ROC curve obtained for the model shows a very good discriminant capacity for the SVR-20, with a 0.83 AUC value. The main conclusion of this study is that the Spanish adaptation of SVR-20 is a good instrument to predict the risk of sexual violence.     

Study of empathy in a Spanish sex offender sample

International research has emphasised that empathy is a relevant factor of sex offending. The main goal of this study is to explore, in a Spanish sex offender sample, the relationship between empathy deficits and sex crime for various types of victims. This study also analyses the positive effect that psychological treatment could have on empathy. For this purpose, 118 non-sex offenders were compared on an adapted version of Rape Empathy Measure to 39 treated rapists and 34 untreated rapists. Results show that the untreated rapists have lower empathy levels than non-sex offenders. Nevertheless, the treated rapists scored higher on empathy than the other two groups assessed, untreated rapists and non-sex offenders. Lastly, some suggestions are provided for future research in terms of the assessment of empathy and other factors related to sexual aggression.     

Gender differences in psychopathy in a Swedish offender sample

In this study we examined gender differences in the PCL:SV employing a variety of statistical methods with two subsets of psychopathic individuals drawn from larger samples of 129 female and 499 male Swedish offenders. The larger samples included forensic psychiatric patients, forensic psychiatric evaluees and criminal offenders. We found gender differences in antisocial behavior, as defined in factor 2 of the PCL:SV, with female psychopaths (PCL:SV>or=18) displaying significantly more lying, deceitfulness and lack of control, while male psychopaths were more antisocial as measured by the PCL:SV. We conclude that it might be meaningful to use gender specific definitions in the assessment of psychopathy or, alternatively, slightly revise the diagnostic tools. Our results support the use of the three-factor model of the PCL-R and PCL:SV introduced by Cooke and Michie (2001) in female populations.     

Field validity of the Psychopathy Checklist-Revised in sex offender risk assessment

Several studies have concluded that scores from Hare's (2003) Psychopathy Checklist-Revised (PCL-R) predict reoffense among sexual offenders, but most of those studies examined the predictive validity of scores from trained research staff, not clinicians in the field scoring the measure as part of actual forensic assessments. Therefore, we examined the field validity of PCL-R scores that forensic evaluators assigned to 333 male sexual offenders who underwent evaluations during a civil commitment selection process. Overall, no PCL-R score was a significant predictor of sexually violent recidivism. Facet 4 was the only PCL-R score with an area under the curve (AUC) greater than .50 (AUC = .53, p = .85) and the only PCL-R score that approached statistical significance for predicting the combined category of violent or sexually violent offending (AUC = .63, p = .08). However, scores from a subset of evaluators revealed stronger predictive effects, indicating that predictive validity was higher for scores from some evaluators than others. Overall, these results suggest that the stronger predictive validity values in controlled research studies may not apply to all evaluators when the PCL-R is administered in the field.     

Relations between psychopathy facets and externalizing in a criminal offender sample

The construct of psychopathy is viewed as comprising distinctive but correlated affective-interpersonal and social deviance facets. Here, we examined these facets of Hare's Psychopathy Checklist-Revised (PCL-R) in terms of their associations with the externalizing dimension of adult psychopathology, defined as the common factor underlying symptoms of conduct disorder, adult antisocial behavior, alcohol use/abuse, and drug abuse, along with disinhibitory personality traits. Correlational analyses revealed a strong relationship between this externalizing dimension and the social deviance facet of psychopathy (r = .84), and a lesser relationship with the emotional-interpersonal component (r = .44). Structural models controlling for the moderate overlap between the PCL-R factors revealed that externalizing was substantially related to the unique variance in the social deviance features of psychopathy, but unrelated to the unique variance of the emotional and interpersonal features whether modeled together or as separate factors. These results indicate that the social deviance factor of the PCL-R reflects the externalizing dimension of psychopathology, whereas the emotional-interpersonal component taps something distinct aside from externalizing. In addition, based on our finding of an association between PCL-R social deviance and externalizing, we were able to predict new relations between this facet of psychopathy and criterion variables, including nicotine use and gambling, that have previously been linked to externalizing. Implications for future research on the causes and correlates of psychopathy are discussed.     

Associations among early abuse, dissociation, and psychopathy in an offender sample

Theorists have postulated that some variants of psychopathy result from childhood abuse and neglect. Dissociative symptoms are also thought to arise from abuse. To date, the conjoint associations among abuse, dissociation, and psychopathy have not been examined systematically. Some have hypothesized that abuse relates primarily to the affective symptoms of psychopathy, with dissociative experiences mediating this relationship. Others have suggested that abuse more directly affects the impulsive lifestyle features of psychopathy. The authors used structural equation modeling to examine these hypotheses in a sample of 615 male offenders who had completed a retrospective self-report measure of childhood abuse, the Dissociative Experiences Scale, and R. D. Hare's (2003) Psychopathy Checklist--Revised. Abuse exerted no direct or indirect effect on the core interpersonal and affective features of psychopathy but was directly related to the facet of psychopathy associated with an impulsive and irresponsible lifestyle. Implications for psychopathy subtypes are discussed.     

A theoretically informed meta-analysis of the risk for general and violent recidivism for mentally disordered offenders

Mentally disordered offenders (MDOs) pose a significant challenge for forensic and correctional staff charged with managing them in a safe and humane manner. As with non-disordered offenders, it is important to identify the factors that are predictive of recidivism and can serve as treatment targets for MDOs. The present meta-analysis evaluated the relative predictive validity of the risk/need domains from the General Personality and Cognitive Social Learning (GPCSL) perspective and variables taken from the clinical perspective. The search yielded a total of 126 studies reporting on 96 unique samples (N = 23,900). Results indicated that all risk/need domains under the GPCSL perspective were significantly related to both general and violent recidivism. In contrast, the majority of clinical variables (with the exception of antisocial personality/psychopathy) were not predictive of either outcome. These findings emphasize the importance of identifying appropriate risk factors for MDOs.     

Crime scene actions and offender characteristics in a sample of Finnish stranger rapes

The crime scene actions employed by offenders in stranger rapes were analysed in relation to offender characteristics. Data were drawn from an official police database and consisted of stranger rapes occurring in Finland between 1992 and 2001 (n = 100). The structure of dichotomous variables derived through a content analysis of crime scene actions and offender characteristics were analysed with non‐metric multidimensional scaling (MDS). The first analysis revealed three separate action themes, with thematic emphases on Hostility, Involvement or Theft. The MDS‐solution for offender characteristics suggested four themes: Conventional; Psychiatric/Elderly; Criminal/Violent; and Criminal/Property. Each case was assigned to one of the themes or as a hybrid in order to analyse the associations between action themes and characteristics. The only significant association was found between the action theme, Theft and characteristics theme Criminal/Property. The results are discussed in relation to previous research.

Factor structure and correlates of the dissociative experiences scale in a large offender sample

The authors examined the psychometric properties, factor structure, and construct validity of the Dissociative Experiences Scale (DES) in a large offender sample (N = 1,515). Although the DES is widely used with community and clinical samples, minimal work has examined offender samples. Participants were administered self-report and interview measures, and a subsample was followed longitudinally to determine criminal and violent recidivism. The DES exhibited good psychometric properties, but an identified three-factor structure was of questionable replicability. Moreover, the DES factors displayed no evidence of differential correlates. DES total scores were correlated with trauma-related variables even after controlling for negative affectivity. Total scores were related to measures of antisocial behavior and aggression but did not predict recidivism. These findings support the reliability and construct validity of the DES in offenders but raise questions regarding the clinical utility of the DES factor scores above and beyond that of the total score.     

Taxometric analyses of borderline personality features in a large-scale male and female offender sample

Few studies to date have examined the extent to which borderline personality features are best construed as representing an underlying dimension or a discrete class or taxon. The authors conducted taxometric analyses using a large-scale sample of male (n=787) and female (n=368) prison inmates who had completed the Personality Assessment Inventory (L. C. Morey, 2007). Analyses based on the 4 subscales of the Borderline Features Scale offered compelling support for a dimensional structure in both the full sample and the female subsample--even after controlling for the potentially confounding effects of negative response distortion. Theoretical and pragmatic implications of these findings are reviewed.     

Co-occurring mental health and substance use problems in offenders: implications for risk assessment

We undertook a secondary data analysis to study issues relevant to co-occurring mental health and substance disorder in a combined sample of offenders (N = 3,197). Using the Personality Assessment Inventory, we compared the frequency of depressive, traumatic stress, and personality disorder symptom elevations across offenders with and without substance problems, identified the extent to which co-occurring problems were accompanied by risk factors for suicide and aggression, and tested for gender differences. Offenders with substance problems were more likely than others to have increased mental health problems and risk factors for suicide or aggression. Women with substance problems, compared with men, had higher depression, traumatic stress, and borderline features, in addition to lower antisocial features. The frequency with which suicide and aggression risk factors were associated with mental health problems was generally similar across men and women. Measurement issues relevant to co-occurring disorder and risk assessment are discussed.     

Psychological assessment, treatment, and outcome with sex offenders

The frequency and impact of sexual offenses have led to the recent enactment of sexual "predator" laws. Such laws are intended to reduce sexual violence through treatment and involuntary confinement. Sixty years ago, similar laws identifying "sexual psychopaths" were enacted and, in many states, eventually repealed for multiple reasons; among those reasons was an inability to demonstrate that treatment had any significant impact on recidivism. That inability forced us to reexamine, among other issues, the population(s) which undergo treatment, the outcomes that are used to measure treatment effectiveness, and the processes that constitute treatment itself. Those issues are considered in this paper through a review of treatment programs based on psychodynamic, behavioral, and cognitive-behavioral theories. Although the evidence is sparse, it is fair to conclude that the latter have been found to be effective. We call for dynamic measures, effective treatments, and the resources necessary for both developments.     

Child versus peer/adult offenders: A critical review of the juvenile sex offender literature

Sexual offenses are serious crimes and it is believed that adolescents perpetrate 20% of all sexual assaults and 50% of all child sexual abuse (Barbaree & Marshall, 2006). To better understand the etiology of juvenile sexual offending, researchers have explored differences between those who offend children versus those who offend peers/adults. This paper critically reviewed 21 studies that compared juvenile sex offenders who abused children with those who abused peers/adults on a variety of variables including victim, offense, and offender characteristics; psychosocial variables; and predictors and rates of recidivism. Strengths and weaknesses of these studies as well as future directions for the literature are discussed. Common methodological limitations of victim-age based comparisons of juvenile sex offenders included inconsistent definitions, low-powered studies, lack of standardized measures, and recidivism data based solely on conviction rates. Overall, many inconsistent findings limit our ability to give overarching conclusions; however, the research does suggests that not only is it important to examine child and peer/adult offenders, but mixed offenders (i.e., offender with both child and peer victims) as a distinct group need to be included in comparisons as well.     

Two-, three-, and four-factor PCL-R models in applied sex offender risk assessments

The authors compared 2-, 3-, 4-factor, and 2-factor/4-facet Psychopathy Checklist-Revised (PCL-R) models in a previously unpublished sample of 1,566 adult male sex offenders assessed under applied clinical conditions as part of a comprehensive state-mandated community notification risk assessment procedure. "Testlets" significantly improved the performance of all models. The 3-factor model provided the best fit to the current data, followed by the 2-factor/4-facet model. The 2-factor model was not supported.     

Validity of the Externalizing Spectrum Inventory in a criminal offender sample: relations with disinhibitory psychopathology, personality, and psychopathic features

The Externalizing Spectrum Inventory (ESI; Krueger, Markon, Patrick, Benning, & Kramer, 2007) provides a self-report based method for indexing a range of correlated problem behaviors and traits in the domain of deficient impulse control. The ESI organizes lower order behaviors and traits of this kind around higher order factors encompassing general disinhibitory proneness, callous-aggression, and substance abuse. In the current study, we used data from a male prisoner sample (N = 235) to evaluate the validity of ESI total and factor scores in relation to external criterion measures consisting of externalizing disorder symptoms (including child and adult antisocial deviance and substance-related problems) assessed via diagnostic interviews, personality traits assessed with self-reports, and psychopathic features as assessed with both interviews and self-reports. Results provide evidence for the validity of the ESI measurement model and point to its potential usefulness as a referent for research on the neurobiological correlates and etiological bases of externalizing proneness.     

Objective risk, subjective risk, and colorectal cancer screening among a clinic sample

Among cancers, colorectal (CRC) is the third most incident and the second most lethal. Although screening for the disease has been shown to be effective in reducing morbidity and mortality, screening rates remain low. Risk of disease has been shown to increase screening uptake, but different types of risk may influence intent to screen, screening in a timely manner, or participating in screening at all. A cross-sectional design was used to select a diverse sample of CRC asymptomatic patients 50 or more years of age (N=104) visiting one of three Midwestern medical clinics. Results showed a positive relationship between receipt of CRC screening and planning to screen for CRC in the future. Objective risk factors (personal/family history and having a primary care physician) were associated with CRC screening uptake and screening within the time intervals recommended by professional screening guidelines, but subjective risk did not obtain significance for screening participation. Both objective (primary care physician) and subjective risk (long-term comparative risk, knowledge) were associated with future plans to screen. Findings suggest that CRC screening behaviors may be differentially influenced by type of risk.     

Violence risk assessment and women: predictive accuracy of the HCR-20 in a civil psychiatric sample

Research to date has not adequately demonstrated whether the HCR-20 Violence Risk Assessment Scheme (HCR-20; Webster, Douglas, Eaves, & Hart, 1997), a structured violence risk assessment measure with a robust literature supporting its validity in male samples, is a valid indicator of violence risk in women. This study utilized data from the MacArthur Study of Mental Disorder and Violence to retrospectively score an abbreviated version of HCR-20 in 827 civil psychiatric patients. HCR-20 scores and predictive accuracy of community violence were compared for men and women. Results suggested that the HCR-20 is slightly, but not significantly, better for evaluating future risk for violence in men than in women, although the magnitude of the gender differences was small and was largely limited to historical factors. The results do not indicate that the HCR-20 needs to be tailored for use in women or that it should not be used in women, but they do highlight that the HCR-20 should be used cautiously and with full awareness of its potential limitations in women.     

A multisite comparison of actuarial risk instruments for sex offenders

Four actuarial instruments for the prediction of violent and sexual reoffending (the Violence Risk Appraisal Guide [VRAG], Sex Offender Risk Appraisal Guide [SORAG], Rapid Risk Assessment for Sex Offender Recidivism [RRASOR] and Static-99) were evaluated in 4 samples of sex offenders (N = 396). Although all 4 instruments predicted violent (including sexual) recidivism and recidivism known to be sexually motivated, areas under the receiver operating characteristic (ROC) were consistently higher for the VRAG and the SORAG. The instruments performed better when there were fewer missing items and follow-up time was fixed, with an ROC area up to .84 for the VRAG, for example, under such favorable conditions. Predictive accuracy was higher for child molesters than for rapists, especially for the Static-99 and the RRASOR. Consistent with past research, survival analyses revealed that those offenders high in both psychopathy and sexual deviance were an especially high-risk group.
