The Level of Service/Case Management Inventory (LS/CMI) and the Youth version (YLS/CMI) generate an assessment of risk/need across eight domains that are considered to be relevant for girls and boys and for women and men. Aggregated across five data sets, the predictive validity of each of the eight domains was gender-neutral. The composite total score (LS/CMI total risk/need) was strongly associated with the recidivism of males (mean r = .39, mean AUC = .746) and very strongly associated with the recidivism of females (mean r = .53, mean AUC = .827). The enhanced validity of LS total risk/need with females was traced to the exceptional validity of Substance Abuse with females. The intra-data set conclusions survived the introduction of two very large samples composed of female offenders exclusively. Finally, the mean incremental contributions of gender and the gender-by-risk level interactions in the prediction of criminal recidivism were minimal compared to the relatively strong validity of the LS/CMI risk level. Although the variance explained by gender was minimal and although high-risk cases were high-risk cases regardless of gender, the recidivism rates of lower risk females were lower than the recidivism rates of lower risk males, suggesting possible implications for test interpretation and policy.  相似文献

The present investigation examined the predictive accuracy of the Youth Level of Service/Case Management Inventory (YLS/CMI) for youth and adult recidivism in a Canadian sample of 167 youths (93 males, 74 females) charged with serious offenses who received psychological services from a community mental health outpatient clinic. Youths were followed for an average of 7 years in the community, and predictive accuracy was examined for several recidivism outcomes as a function of gender, ethnicity, and developmental age group. YLS/CMI total scores significantly predicted all recidivism categories in the overall sample (area under the curve values ranged from 0.66 to 0.77) although the instrument as a whole, and its criminogenic needs, demonstrated somewhat stronger and more consistent predictive accuracy for youth outcomes. The YLS/CMI also demonstrated significant predictive accuracy within demographic subgroups. The implications of these findings are discussed in terms of the use of risk-need assessment tools in providing clinical assessment, treatment, and case management services to diverse young offender groups.

Historically, minority youth have experienced harsher punishments and more negative outcomes than White youth even when risk assessment is used. The current study investigated the role of ethnicity in an understudied dispositional decision–program referral–and the outcomes associated with said referral using a sample of juvenile offenders (N = 2,678). The study used the Youth Level of Service/Case Management Inventory (YLS/CMI) to determine (1) if ethnicity predicted program referral when accounting for risk assessment and (2) if program referral predicted recidivism. Results indicated that ethnicity predicted program referral, and program referral predicted recidivism. Future directions for Disproportionate Minority Contact (DMC) research and implications for court officials are discussed.  相似文献

Purpose . The predictive validity of the psychopathy checklist‐youth version (PCL:YV) and Youth Level of Service/Case Management Inventory (YLS/CMI) for juvenile offenders were compared to examine whether a broad needs–risk tool predicted violence better than a focused individual assessment of psychopathy. Methods . 94 adolescents from residential and secure units were interviewed and assessed using the PCL:YV and YLS/CMI. Total scores were retrospectively applied to staff‐recorded incidents of violence, total number of charges and convictions and formally recorded assaults. The predictive accuracy of each tool was assessed using correlational and receiver operator characteristic analyses. Results . The PCL:YV was a better predictor of staff‐recorded violence than the YLS/CMI; both instruments were similar in their ability to predict total number of charges and convictions and assaults. When subdivided by gender, the correlations for predicting staff recorded violence in male participants were significantly higher than for female participants for both test instruments. Both instruments were broadly equivalent in their association with assaults and charges and convictions by gender. Conclusion . The PCL:YV is a better predictor of recorded violence than the YLS/CMI, but for charges and convictions and assaults, the YLS/CMI and PCL:YV were comparable for UK adolescent offenders. When recalculated to exclude the likelihood of predictor–criterion overlap, the results were the same. These findings are discussed in relation to the value of using risk–needs assessment instruments as compared with scales with a more psychopathological and personality focus.  相似文献

Offender assessment in corrections has advanced considerably over the last several decades. Currently, it is not uncommon to find correctional professionals using any number of objective standardized assessment instruments. While many of these instruments possess face validity as well as statistical predictive validity, more work is needed to test classification protocol on new populations, and in various correctional environments. The current paper investigates the predictive validity of the Youth Level of Service/Case Management Inventory (YLS/CMI) within an institutional setting. Specifically, the composite score rendered from the YLS/CMI is used to predict institutional misconduct. The YLS/ CMI was found to effectively differentiate between two levels of offender risk/ need, and was significantly related to outcome using several different statistical techniques.  相似文献

In this retrospective study, the interrater reliability and predictive validity of 2 risk assessment instruments for sexual violence are presented. The SVR-20, an instrument for structured professional judgment, and the Static-99, an actuarial risk assessment instrument, were coded from file information of 122 sex offenders who were admitted to a Dutch forensic psychiatric hospital between 1974 and 1996 (average follow-up period 140 months). Recidivism data (reconvictions) from the Ministry of Justice were related to the risk assessments. The base rate for sexual recidivism was 39%, for nonsexual violent offenses 46%, and for general offenses 74%. Predictive validity of the SVR-20 was good (total score: r = .50, AUC = .80; final risk judgment: r = .60, AUC = .83), of the Static-99 moderate (total score: r = .38, AUC =.71; risk category: r = .30, AUC = .66). The SVR-20 final risk judgment was a significantly better predictor of sexual recidivism than the Static-99 risk category.  相似文献

PurposeTo examine the inter-rater reliability of two risk assessment tools: The Level of Service Inventory-Revised (LSI-R) and the Youth Level of Service/Case Management Inventory (YLS/CMI).MethodsTwo identical experiments are reported. For both studies, a random sample of 10 offenders were interviewed and videotaped with each tool (totaling 20 offenders). The tapes were then shown to a random selection of 20 raters (for a total of 40 raters) employed at a state agency. The fully-crossed design allowed each of the raters to rate the each of the cases, resulting in 200 total risk score observations for each tool. Inter-rater reliability analyses were then conducted.ResultsThe LSI-R demonstrated adequate to fair reliability, with certain domains showing lower reliability. Overall, the LSI-R had an ICC of .65. The YLS/CMI demonstrated higher reliability (ICC of .78). In addition, for the LSI-R study, comparisons were made between staff raters who work in a facility versus those in the community (e.g., probation officers). For the YLS/CMI study, comparisons were made between incarcerated offenders versus probationers. Neither comparison yielded consistent differences.ConclusionsThe YLS/CMI is generally reliable. The LSI-R showed less reliability. However, each study showed certain domains with less than ideal reliability.  相似文献

Psychopathy as conceptualized with Hare's Psychopathy Checklist Revised, PCL-R, has attracted much research during the 1990s. In the Scandinavian countries, few studies that empirically support the validity of North American risk assessment techniques in our regional context have been published. The purpose of this paper is to explore the predictive power of the PCL-R in a population of personality-disordered violent offenders subjected to forensic psychiatric evaluation in Sweden. Following release from prison (n = 172), discharge from forensic psychiatric treatment (n = 129), or probation (n = 51), a total of 352 individuals were followed for up to 8 years (mean = 3.7 years) with reconviction for violent crime as endpoint variable (base rate 34%). As the estimate of predictive power, the area under the curve of a receiver operating characteristic (AUC of ROC) analysis was calculated. For PCL-R scores to predict 2-year violent recidivism, AUC of ROC was .72 (95% CI: .66–.78). In addition, the personality dimension of psychopathy (Factor 1) and the behavioral component (Factor 2) both predicted 2-year recidivism significantly better than random: AUC of ROC .64 (95% CI: .57–.70) and .71 (95% CI: .65–.77), respectively. We conclude that psychopathy is probably as valid a predictor of violent recidivism in Swedish forensic settings as seen in previous North American studies.  相似文献

The Static-99 is a widely used actuarial risk assessment instrument. Various international validation studies have found satisfactory to good predictive validity for the Static-99, with the area under the curve (AUC) between 59% and 95%. This study is the first evaluation of the predictive accuracy of the Static-99 among sex offenders in Switzerland. The Static-99 scores of 69 violent/sex offenders in Switzerland were assessed using data from their psychiatric assessments. Recidivism was operationalized as reconviction assessed from penal records. The Static-99 risk levels were predictive for recidivism (AUC = .758) among our population. The results are discussed on the basis of the literature.  相似文献

Abstract

Youth gangs are ubiquitous around the world and have been problematic for the social and criminal justice agencies. Despite widespread public concern, there has been relatively scarce empirical scrutiny of youth gangs internationally and little outside of America and Europe. In particular, the activities of youth gangs, the function of gang membership, the criminogenic needs of gang-affiliated youth, and the risk of criminal recidivism for gang-affiliated youth remain unclear. Against this background, this study explored the sociodemographic characteristics, risk and rate of criminal recidivism in a cohort of 165 male youth offenders in Singapore, of which 58 were gang-affiliated. Multivariate analyses revealed that gang-affiliated youth offenders were significantly more likely to have histories of substance use, weapon use and violence than nongang-affiliated youth offenders. Gang-affiliated offenders also scored higher on measures of risk for recidivism (SAVRY and YLS/CMI), and engaged in violent and other criminal behaviors more frequently during follow-up. These differences indicate a significant relationship between gang affiliation and criminal recidivism in youth offenders. Furthermore, these findings have important clinical and policy implications, indicating an increased requirement for additional and more intensive assessment and tailored interventions for gang-affiliated youth offenders.  相似文献

Purpose. This study examined the degree to which child sex offenders demonstrated crossover in victim choice, as defined by age, gender, and relationship to the offender. It also aimed to explore the direction of the shift in victim type with repeated offending within each of the three domains and to identify variables predictive of crossover behaviour. Method. The sample comprised 128 adult male child sexual offenders. All had offended against multiple victims and were attending a community‐based assessment and treatment service for sexual offenders at the time of data collection. Variables were gathered, coded, and de‐identified from a manual search through clinical casenotes, from client assessment reports as well as from supplementary information consisting of sentencing remarks or other professional reports. Results. More than half of the sample (63.3%, N = 81) demonstrated crossover in victim type across at least one domain. Crossover was 48.0% (N = 59) in the age domain, 22.0% (N = 28) in the gender domain, and 25.8% (N = 33) in the relationship to victim domain. Crossover offending was associated with number of victims but unrelated to frequency of offending or to recidivism risk as assessed by a standard risk assessment instrument. Transitional matrices showed general stability in victim type across offences within the gender and relationship domains, but lower stability within the age domain. Conclusions. Crossover offending behaviour was found to be frequent in the age domain, but the high frequency of crossover in this domain may be artifactual. Crossover offending was less frequent in the gender and relationship domains, but should be taken into account in risk assessment. Victim type shows stability across multiple offences in the gender and relationship to victim domains. Analysis of victim type across multiple offences should be replicated under conditions where disclosure of offending is maximized.  相似文献

Psychopathy has been linked to violent reoffending in men, but the findings in women have been contradictory. The aim of this study was to examine the predictive validity of the Psychopathy Checklist-Revised (PCL-R) for violent recidivism in a nationwide sample of female violent offenders. The offenders (n = 48) had been assessed by the PCL-R and were followed after their release from prison or a psychiatric hospital. The average follow-up period was 8 years. Of the offenders, 16 (33%) had been reconvicted of a violent crime. Current findings of the performance indicators did not support the use of the PCL-R as a predictive instrument assessing risk of violent recidivism in females. The findings indicate that impulsivity plays a crucial role in female violent recidivism and that the PCL-R should be used with caution in risk assessment with female populations.  相似文献

Risk-need assessment is widely accepted as best practice with juvenile offenders and is underpinned by a healthy research literature on risk assessment inventories. Previous studies have found both similarities and differences on risk measures when gender and racial/ethnic subgroups have been compared. Differential validity has been examined, but differential prediction has been overlooked. The current study undertook gender and ethnic comparisons for a large sample (n = 3568) of community-based juvenile offenders who were evaluated using the Australian Adaptation of the Youth Level of Service/Case Management Inventory (YLS/CMI-AA). Analyses showed various gender and ethnic differences at the item level, across domain scores and on the total inventory score, but not for validity indices. However, 1-year reoffending rates for youth in three classification categories (low, moderate, high) varied by gender and ethnicity. The findings were related to contemporary understandings of the risk factors for offending and the dynamics of crime for gender/ethnic subgroups. It is argued that in spite of these subgroup differences, a generic inventory such as the YLS/CMI-AA can be used fairly with various subgroups. Recommendations for how this could be accomplished are provided. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献

ABSTRACT

This paper reports the findings of a systematic search of published literature which reports the predictive validity of violence risk assessment tools specifically designed for use with youth. A total of 38 studies, involving 9,307 participants, reported data for six different tools; the most common of which were the SAVRY and the YLS/CMI. Each of the tools demonstrated at least moderate levels of predictive validity, with the predictive validity of several newer assessment tools yet to be established. The results provide an up-to-date overview of the state of knowledge in an area in which practitioners make choices about which tools to use on an almost daily basis. It is important that practitioners are aware of the strength of evidence that is available to support the choice of violence risk assessment tools and the interpretation of results.  相似文献

This study explored change in dynamic risk for violence using the Clinical and Risk Management subscales of the Historical Clinical and Risk Management-20 version 3 (HCR-20 v3) and sought to determine whether change was associated with violent recidivism. The association between the magnitude of change and psychopathy was also assessed. Participants were 40 male (n = 32) and female (n = 8) forensic psychiatric inpatients discharged from a secure forensic mental health service. Results showed that participants significantly improved on the HCR-20v3 Clinical subscale but significantly worsened on the Risk Management subscale. Psychopathy was unrelated to change in Clinical and Risk Management subscales. The hypothesis that changes in dynamic risk would predict recidivism over and above total pre-treatment risk (HCR-20v3 Total score) and psychopathy was not supported. These results suggest that improvements in mental state risk factors alone are insufficient with regard to lowering violence risk.  相似文献

The current study seeks to extend routine activity theory by examining how gender conditions the relationship between leisure activities and adolescent delinquency. Using OLS regression with a sample of high school students from Toronto (n = 2,209), we find that (1) engaging in more unstructured and unsupervised activities with peers is associated with delinquency more strongly for boys than for girls, but is associated with substance use equally across gender; (2) this pattern is likely due to gender differences in the locations or contexts of leisure activities; and (3) prosocial leisure activities are associated with less delinquency only for boys. In general, routine activity theory appears apt at explaining the substance use of boys and girls, but is less capable of explaining the property and violent offending of girls. We discuss our findings and their implications for the growing body of research extending routine activity theory to explain gender differences in delinquency.  相似文献

Research Summary Over the past two decades, researchers have been increasingly interested in measuring the risk of offender recidivism as a means of advancing public safety and of directing treatment interventions. In this context, one instrument widely used in assessing offenders is the Level of Service Inventory‐Revised (LSI‐R). Recently, however, the LSI‐R has been criticized for being a male‐specific assessment instrument that is a weak predictor of criminal behavior in females. Through the use of meta‐analytic techniques, we assessed this assertion. A total of 27 effect sizes yielded an average r value of .35 ([confidence interval] CI = .34 to .36) for the relationship of the LSI‐R with recidivism for female offenders (N= 14,737). When available, we also made within‐sample comparisons based on gender. These comparisons produced effect sizes for males and females that were statistically similar. Policy Implications These results are consistent with those generated in previous research on the LSI‐R. They call into question prevailing critiques that the LSI‐R has predictive validity for male but not for female offenders. At this stage, it seems that corrections officials should be advised that the LSI‐R remains an important instrument for assessing all offenders as a prelude to the delivery of treatment services, especially those based on the principles of effective intervention. Critics should be encouraged, however, to construct and validate through research additional gender‐specific instruments that revise, if not rival, the LSI‐R.  相似文献

The effectiveness of the Self-Appraisal Questionnaire (SAQ) in providing estimates for predicting violent and nonviolent recidivism over a 9-year period is examined. The SAQ is a quantitative risk/need instrument consisting of 72 items that compose eight subscales. There were 657 federally sentenced Canadian male offenders who completed the SAQ prior to their release and were followed up for 9 years (108 months) at 4-month intervals. Consistent with previous predictive studies, the results presented here demonstrate that the SAQ has adequate predictive validity.  相似文献

The authors demonstrate a statistical bootstrapping method for obtaining unbiased item selection and predictive validity estimates from a scale development sample, using data (N = 256) of Epperson et al. [2003 Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) technical paper: Development, validation, and recommended risk level cut scores. Retrieved November 18, 2006 from Iowa State University Department of Psychology web site: http://www.psychology.iastate.edu/ approximately dle/mnsost_download.htm] from which the Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) was developed. Validity (area under receiver operating characteristic curve) reported by Epperson et al. was .77 with 16 items selected. The present analysis yielded an asymptotically unbiased estimator AUC = .58. The present article also focused on the degree to which sampling error renders estimated cutting scores (appropriate to local [varying] recidivism base rates) nonoptimal, so that the long-run performance (measured by correct fraction, the total proportion of correct classifications) of these estimated cutting scores is poor, when they are applied to their parent populations (having assumed values for AUC and recidivism rate). This was investigated by Monte Carlo simulation over a range of AUC and recidivism rate values. Results indicate that, except for the AUC values higher than have ever been cross-validated, in combination with recidivism base rates severalfold higher than the literature average [Hanson and Morton-Bourgon, 2004, Predictors of sexual recidivism: An updated meta-analysis. (User report 2004-02.). Ottawa: Public Safety and Emergency Preparedness Canada], the user of an instrument similar in performance to the MnSOST-R cannot expect to achieve correct fraction performance notably in excess of what is achievable from knowing the population recidivism rate alone. The authors discuss the legal implications of their findings for procedural and substantive due process in relation to state sexually violent person commitment statutes and the Supreme Court's Kansas v. Hendricks decision regarding the constitutionality of such statutes.  相似文献

Purpose. The goal of the present research was to develop a screening measure to assist in identifying offenders at risk for drop‐out or expulsion from correctional programmes. Methods. Non‐Aboriginal male offenders (N = 5,247) were randomly divided into a development sample (N = 2,617) and a validation sample (N = 2,630). In the development sample, individual predictors were identified through univariate and multivariate analyses, weighted based on their relationship with drop‐out/expulsion, and combined into a composite measure we called the drop‐out risk screen (DRS). Results. The DRS consists of five items, including static and dynamic risk factors for recidivism as well as motivation for intervention. It significantly predicted drop‐out/expulsion in the development sample (area under the receiver operating characteristic curve [AUC]= .72) and performed similarly in the validation sample (AUC = .70). Conclusions. The results indicate that the DRS is a valid screening instrument for risk of drop‐out/expulsion. Prior to commencement of a treatment programme, offenders with high scores on the DRS could be more thoroughly assessed and, if necessary, targeted with pre‐treatment efforts to increase their motivation and general readiness for treatment.  相似文献
