The Level of Service Inventory (Ontario Revision) scale validation for gender and ethnicity : addressing reliability and predictive validityHogg, Sarah Marie 14 April 2011
Previous investigations of the Level of Service Inventory Ontario Revision (LSI-OR) have examined individual subgroups of offenders (e.g., women, Aboriginal offenders), which has made comparisons of its predictive validity between specific offender groups suspect. This study was conducted on a complete cohort of 26,450 offenders who were released from Ontario provincial correctional facilities, sentenced to a conditional sentence, or who began a term of probation in 2004. Participants were followed up for at least four years to collect recidivism information on numerous subgroups of offenders including males (81.7%), females (18.3%), Aboriginal (6.4%), Black (7.3%) and Caucasian offenders (59.2%). Analyses revealed that the LSI-OR scores are positively correlated with recidivism (r = .441, p < .001), and similar correlations were found for all offenders regardless of gender or race, (Aboriginal r = .377, p < .001; Black, r = .420, p < .001; Caucasian, r = .417, p < .001; Male, r = .439, p < .001; Female, r = .426, p < .001). LSI-OR scores are also correlated with severity of the recidivism offence, (r = .098, p <.001) indicating that higher LSI-OR scores are related to higher offence severity for all ethnicities, sentence types, and genders. These findings indicate that the LSI-OR is an effective risk assessment tool for use among different ethnicities, sentence types and genders for provincially sentenced offenders in Ontario.

The level of service inventory and female offenders : addressing issues of reliability and predictive abilityBrews, Albert Lawson 14 April 2009
The legitimacy of classifying female offenders in the correctional system has been disputed (especially the application of male-normed risk assessment tools), and yet, there is a need to accurately determine the risk of re-offending and the criminogenic needs of the offender along with general and specific issues (i.e., responsivity) that will encourage successful program delivery. The Level of Service Inventory Ontario Revision (LSI-OR; Andrews, Bonta & Wormith, 1995) is an assessment tool used throughout Ontarios probation services and provincial institutions. Although the first edition of the LSI was based primarily on a male sample, later revisions included norms for female offenders based on samples spanning three continents (Blanchette & Brown, 2006). Although its reliability and predictive validity has been demonstrated across many field settings and offender populations, few studies (e.g., Rettinger, 1998) have addressed the question of predictive validity on a sufficiently large sample of female offenders to convince the skeptics of the LSI-ORs applicability to women (Blanchette & Brown).<p>
The current study examined internal consistency, the ability to discriminate recidivists from non-recidivists with t-tests, and the capacity to predict recidivism with correlation and receiver operating characteristic analysis. The sample consisted of 2831 female offenders who were either released from a provincial correctional facility, completed a conditional sentence in the community, or completed a sentence of probation in Ontario during a one year period (2002/2003). Special consideration was given to female offenders from different disposition groups, with different racial backgrounds, with mental health issues and with prior victimization. The LSI-OR had very strong internal consistency and was able to distinguish offenders who committed a re-offence from those who did not commit a re-offence; both when considering the scale as a whole and when considering individual subscales. The LSI OR was also found to predict recidivism for all female offenders. It also predicted recidivism for all subgroups with the exception of female offenders released on a conditional sentence and who had been previously victimized. While the use of the LSI-OR to assess provincial female offenders is supported, however, new risk levels are suggested to increase the predictive ability and reduce the potential for over-classification.

Risk assessment and community management : the relationship between implementation quality and recidivismLuong, Duyen 01 October 2007
Risk assessment and case management are two important aspects of young offender corrections and reintegration. Evaluating the extent to which case management practices are guided by risk assessment is important because the impact of the risk assessment instrument cannot be adequately assessed if the instrument is not being applied as fully intended. Unfortunately, little research has been devoted to examining the use of risk/need instruments in offender case management. The purpose of the present study was to investigate the link between risk assessment and community case management of young offenders in Saskatchewan and whether adherence to the principles of risk, need, and responsivity vis-à-vis the Level of Service Inventory Saskatchewan Youth Edition (LSI-SK; Andrews, Bonta, & Wormith, 2001) is related to recidivism. <p>Risk assessment and case management data were collected for a total sample of 193 young offenders who were supervised by youth workers from the Saskatoon and Regina probation offices. The sample was followed up for an average of 644 days. The overall recidivism rate was 62.2% with no significant difference in recidivism according to office of supervision, sex, or ethnicity.<p>The LSI-SK total and seven of the subscale scores were significantly, positively correlated with recidivism. Results also indicate that the LSI-SK was being used to guide supervision intensity as well as interventions. Moreover, the present study found that adherence to the need principle was associated with reductions in recidivism. Appropriateness (defined as the presence of interventions for identified needs or absence of interventions for areas that were not identified as needs) correlated significantly with recidivism (r = - .214). Appropriateness was found to be a significant predictor of recidivism after controlling for ethnicity and length of follow up. For every appropriate intervention listed on the case plan, the likelihood of recidivism was reduced by 24%. In terms of inappropriate treatment, under treatment was significantly correlated with recidivism (r = .283) but over treatment was not. Under treatment was a significant predictor of recidivism after controlling for ethnicity and length of follow up. For every identified need that did not have a corresponding intervention, the risk of recidivism increased by 91%. Implications for case management and direction for future research are discussed.

Gender and Risk Assessment in Juvenile Offenders: A Meta-analysisJanuary 2016 (has links)
abstract: Although young males are still the primary perpetrators of juvenile crime, girls are increasingly coming into contact with the criminal justice system. While girls may have different pathways to crime and risks for recidivism than boys, their risk to reoffend is typically assessed using a gender-neutral tool that is based on social learning theory: a theory originally developed and tested on males. With the appropriateness of using gender-neutral tools to assess female criminality coming into question, a number of researchers have searched for a resolution. To date, mixed findings on the predictive validity of risk assessment tools have not provided any definitive answers. To help assess the predictive validity of the Youth Level of Service Inventory, separate meta-analyses were conducted for male and female juvenile offenders using previous studies. The mean effect sizes were compared in order to determine whether the predictive validity is similar for both males and females. With the exception of violent recidivism, results indicate that the YLS/CMI works equally well for male and female offenders. The implications of these findings for theory, research, and correctional policy are discussed. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2016

Initial Drug Court Risk Assessment Scores and Probationers' Completion of Drug Court ProgramsAtkins, Carina T 01 January 2018 (has links)
Drug offenders continue to cost citizens and governments money, while drug courts attempt to rehabilitate offenders and reduce recidivism. The Level of Service Inventory-Revised (LSI-R) is a risk assessment tool used by courts and probation offices to determine needs and risks of offenders, and often determine levels of supervision. The purpose of this quasi experimental study was to determine if there is a statistically significant association between the initial LSI-R scores of offenders entering drug courts and their successful completion of the drug court program. Therapeutic jurisprudence theory, the theoretical framework for this study, suggests that the courts and the law are therapeutic to people and that drug treatment will promote positive behavior changes for the offenders. Data for this study were acquired from a database provided by a Kansas drug court, including initial LSI-R scores, completion records, and demographics of 210 drug court participants. A one-way ANOVA was used to test the hypotheses. Significant statistical results were found, indicating that drug court success was positively associated with the LSI-R score. The study may lead to social change by providing information about participants, most likely to benefit from drug court programs, which will save governments money and make room in the programs for more successful candidates, thus producing more productive citizens in the community.
