The differential predictive validity of the Youth Level of Service/Case Management Inventory: the role of gender

ABSTRACTMost criminogenic risk assessments are developed and empirically validated on samples of boys or samples comprised of mostly boys, and subsequently applied to girls. Using a sample of male (n = 1,267) and female (n = 453) probationers, the purpose of the current study was to examine the potentially differential performance of the Youth Level of Service/Case Management Inventory (YLS/CMI) and the instrument’s eight domains for female juvenile offenders. Findings revealed gender differences in the predictive validity of the YLS/CMI in which girls scored significantly higher on the risk assessment, but recidivated at significantly lower rates than boys two years following the administration of the assessment. The predictive validity of the instrument was impacted by these gender differences in which the YLS/CMI total score was a better predictor of recidivism for boys (area under the curve (AUC) = .623) than girls (AUC = .565). The only subscales that significantly predicted recidivism for girls were the family (AUC = .607) and personality (AUC = .572) domains, whereas all of the subscales significantly predicted recidivism for boys. Directions for future research as well as gender-responsive assessment, programming, and policy implications are discussed.

The Predictive Validity of Savry Ratings for Assessing Youth Offenders in Singapore: A Comparison With YLS/CMI Ratings.

Empirical support for the usage of the SAVRY has been reported in studies conducted in many Western contexts, but not in a Singaporean context. This study compared the predictive validity of the SAVRY ratings for violent and general recidivism against the Youth Level of Service/Case Management Inventory (YLS/CMI) ratings within the Singaporean context. Using a sample of 165 male young offenders (Mfollow-up = 4.54 years), results showed that the SAVRY Total Score and Summary Risk Rating, as well as YLS/CMI Total Score and Overall Risk Rating, predicted violent and general recidivism. SAVRY Protective Total Score was only significantly predictive of desistance from general recidivism, and did not show incremental predictive validity for violent and general recidivism over the SAVRY Total Score. Overall, the results suggest that the SAVRY is suited (to varying degrees) for assessing the risk of violent and general recidivism in young offenders within the Singaporean context, but might not be better than the YLS/CMI.

Predictive Validity of the Youth Level of Service/Case Management Inventory with Youth who have Committed Sexual and Non-Sexual Offenses

The predictive validity of the Youth Level of Service/Case Management Inventory (YLS/CMI) and the use of professional override were examined in a matched sample of youth who committed sexual ( n = 204) and non-sexual ( n = 185) offenses. Based on the actuarial score, the YLS/CMI obtained moderate to strong levels of predictive validity for non-violent, violent, sexual, and technical recidivism in both samples of youth. Probation officers always used override to increase risk level classification and did so at a high level for both sexual ( n = 151; 74.0%) and non-sexual ( n = 77; 41.6%) offending youth. There was a detrimental impact on the predictive validity of the YLS/CMI for youth who received an override adjustment, regardless of offending category. These preliminary findings suggest that the application of override should be carefully considered on instruments such as the YLS/CMI.

Assessing youth offenders in a non-Western context: The predictive validity of the YLS/CMI ratings.

Empirical support for the usage of the Youth Level of Service measures has been reported in studies conducted in the North America, United Kingdom, and Australia. Recent meta-analytic studies on the Youth Level of Service/Case Management Inventory (YLS/CMI) have revealed that the measure has modest to moderate predictive validity for general recidivism, but there are very few studies on the predictive validity of the YLS/CMI ratings for recidivism in non-Western contexts. This study examined the predictive validity of the YLS/CMI 2.0 ratings for general recidivism in a sample of 3,264 youth offenders within a Singaporean context (Mfollow-up = 1,764.5 days; SDfollow-up = 521.5). Results showed that the YLS/CMI 2.0 overall risk ratings and total scores significantly predicted general recidivism for both male and female youth offenders. Overall, the results suggest that the YLS/CMI 2.0 is suited for assessing youth offenders in terms of their risk for general recidivism within a non-Western context.

Impact of Type of Intervention on Youth Reoffending: Are Gender and Risk Level Involved?

The objective of this study was to analyse the impact of the type of intervention on youth reoffending. Moreover, the possible influence that the offender's gender and level of risk could have on this relationship was also explored. Juvenile offenders from four different types of educational interventions participated in the study (N = 210): victim–offender mediation (VOM) as a diversion procedure, and case closure, reprimand, and community service as dispositions. Aged between 14-18 years, they were assessed by means of the Youth Level of Service/Case Management Inventory (YLS/CMI). Recidivism rates were evaluated as the number of new records in a follow-up period of 24 months. Results of this study showed that type of intervention (diversion versus dispositions) had no apparent effect on youth recidivism. Furthermore, an important aspect to consider in youth assessment was the different impact that risk level had on boys’ and girls’ recidivism.

In the eye of the beholder? An examination of the inter-rater reliability of the LSI-R and YLS/CMI in a correctional agency

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.

An Examination of Criminogenic Needs, Mental Health Concerns, and Recidivism in a Sample of Violent Young Offenders: Implications for Risk, Need, and Responsivity

Young offender populations typically display high rates of substance use pathology and mental health concerns, however, little is known regarding how these factors relate to dynamic risk factors for reoffending (criminogenic needs) among young offenders. The present study investigated a Canadian sample of 186 youth charged with serious/violent offenses on measures of psychopathology, substance abuse, risk, and recidivism. Significant relationships were found between measures of substance abuse with most indices of the Youth Level of Service/Case Management Inventory (YLS/CMI), a validated risk assessment tool designed to assess criminogenic risk and need. Furthermore, measures of substance abuse predicted general, violent, and nonviolent recidivism for both youth and adult outcomes to varying degrees. Youth with disruptive behavior disorders, comorbid substance use concerns with another disorder (dual diagnosis), or with two or more disorders evidenced more serious criminogenic need profiles, whereas mood, anxiety, and cognitive disorders were unrelated to criminogenic risk. With the exception of conduct disorder and substance use pathology, mental health concerns tended not to be related to recidivism. The implications of these findings in terms of assessing risk and providing treatment services for young offenders is discussed in relation to the risk-need responsivity (RNR) model of effective correctional intervention.

Does diagnosis affect the predictive accuracy of risk assessment tools for juvenile offenders: Conduct Disorder and Attention Deficit Hyperactivity Disorder

Studies have suggested an increased risk of criminality in juveniles if they suffer from co-morbid Attention Deficit Hyperactivity Disorder (ADHD) along with Conduct Disorder. The Structured Assessment of Violence Risk in Youth (SAVRY), the Psychopathy Checklist Youth Version (PCL:YV), and Youth Level of Service/Case Management Inventory (YLS/CMI) have been shown to be good predictors of violent and non-violent re-offending. The aim was to compare the accuracy of these tools to predict violent and non-violent re-offending in young people with co-morbid ADHD and Conduct Disorder and Conduct Disorder only. The sample included 109 White-British adolescent males in secure settings. Results revealed no significant differences between the groups for re-offending. SAVRY factors had better predictive values than PCL:YV or YLS/CMI. Tools generally had better predictive values for the Conduct Disorder only group than the co-morbid group. Possible reasons for these findings have been discussed along with limitations of the study.

Juvenile offenders and experiences of neglect: The validity of the YLS/CMI with dual-status youth

The extant literature suggests that youth present in both child welfare and juvenile justice systems (dual-status) represent a unique subset of young offenders. Sparse attention has been given to the predictive validity of risk assessment measures with this uniquely vulnerable subpopulation. The focus of this research was the validity of a commonly used recidivism risk/need assessment, the Youth Level of Service/Case Management Inventory (YLS/CMI), with dual-status adolescents. One hundred twenty-eight dual-status youth from a probation division were administered the YLS/CMI and monitored during a twenty-four month follow-up for recidivism. The YLS/CMI demonstrated poor predictive validity for the dual-status youth. Recommendations for future research and policy are presented.

Are Youth Violence Risk Instruments Interchangeable? Evaluating Instrument Convergence in a Sample of Incarcerated Adolescent Offenders

In light of the growing number of youth violence instruments at a clinician’s disposal, this study sought to investigate the interchangeability of two widely validated adolescent violence risk instruments. The concurrent and incremental validity of the Structured Assessment of Violence Risk in Youth (SAVRY) and the Youth Level of Service/Case Management Inventory (YLS/CMI) were evaluated in a young Australian custodial population. A significant degree of dimensional construct overlap between instruments was discovered. Both measures were similarly found to be moderately predictive of general and violent recidivism. Findings indicate that the instruments are potentially substitutable when used to evaluate future violence in these settings. Clinical implications for risk assessment practice are discussed.

The Predictive Validity of Risk Assessment Approaches for Young Australian Offenders

Validation literature on the predictive ability of North American youth violence risk assessment inventories is developing across international settings. Yet no information exists on the utility of the Structured Assessment of Violence Risk in Youth (SAVRY) and the Psychopathy Checklist: Youth Version (PCL:YV),]and little research has been conducted on the Youth Level of Service/Case Management Inventory (YLS/CMI) across Australian young offender populations. The current study investigated the validity of the risk instruments on 213 young people in detention in Victoria, Australia. Findings indicated moderate to strong predictive accuracy for re-offence outcomes across the three inventories for the total sample and for males. The SAVRY was also able to identify the strength of protective factors for young female offenders. The inventories appear to be suitable prediction aides in the Australian youth justice context although further research is required to ascertain their applicability to Australian young female offenders.

Screening Offenders: The Exploration of a Youth Level of Service/Case Management Inventory (YLS/CMI) Brief Screener

Although structured assessments have helped standardize juvenile court processes by systematically measuring risk for recidivism, it has been argued that some assessments lack the ability to perform as a brief screener. This study explored the potential for the original 42-item Youth Level of Service/Case Management Inventory (YLS/CMI) risk assessment to perform as a brief screener for a sample of first-time juvenile offenders in a Midwestern, industrialized county. Results indicated that the original and shortened version of the YLS/CMI significantly predicted 2-year recidivism for male and female offenders. Implications for situationally targeted forms of risk assessment are discussed.

Predictive Validity of Risk Assessments in Juvenile Offenders

This study examined the validity and reliability of the Structured Assessment of Violence Risk in Youth (SAVRY), the Youth Level of Service/Case Management Inventory (YLS/CMI), and the Psychopathy Checklist: Youth Version (PCL:YV) in a sample of Spanish adolescents with a community sanction (N = 105). Self-reported delinquency with a follow-up period of 1 year was used as the outcome measure. The predictive validity of the three measures was compared with the unstructured judgment of the juvenile's probation officer and the self-appraisal of the juvenile. The three measures showed moderate effect sizes, ranging from area under the curve (AUC) = .75 (SAVRY) to AUC = .72 (PCL:YV), in predicting juvenile reoffending. The two unstructured judgments had no significant predictive validity whereas the SAVRY had significantly higher predictive validity compared with both unstructured judgments. Finally, SAVRY protective factor total scores and SAVRY summary risk ratings did not add incremental validity over SAVRY risk total scores. The high base rates of both violent (65.4%) and general reoffending (81.9%) underline the need for further risk assessment and management research with this population.

A cross-validation of the Youth Level of Service/Case Management Inventory (YLS/CMI) among Japanese juvenile offenders.

The main purpose of the current research is to examine the applicability of the Youth Level of Service/Case Management Inventory (YLS/CMI) in a Japanese juvenile offender population. Three hundred eighty-nine youths who were released from the five Juvenile Classification Homes were followed for approximately one and half years. Results show that the YLS/CMI total score significantly predict recidivism. Survival time analysis demonstrates that the YLS/CMI total score also significantly predicted faster time to recidivism. The overall findings support adequate predictive validity of the YLS/CMI total score, but subscales lacked content representativeness and predictive validity in this sample. Canadian and Japanese cultural differences in criminal history and substance abuse are contributors to the lack of content representativeness.

Impact of risk/needs assessment on juvenile probation officers' decision making: Importance of implementation.

The adoption of risk assessment tools has increased in popularity in the juvenile justice system due, in part, to recommendations by the Juvenile Justice Delinquency Prevention Act (JJDPA). However, very little is known about whether adoption of these tools actually effectuates change in the way young offenders are handled. Qualitative and quantitative data were gathered from 111 juvenile probation officers (JPOs) from six probation offices before and twice after standardized, rigorous implementation of the Structured Assessment of Violence Risk for Youth (SAVRY) or the Youth Level of Service/Case Management Inventory (YLS/CMI). The purpose of this study was to examine JPOs' changes in attitudes and case management decisions following implementation of a risk/needs assessment (RNA) tool. There was a significant reduction in JPOs' perceptions of the proportion of young offenders who would reoffend. There were many shifts in JPOs' decision-making to be more consistent with Risk-Need-Responsivity practices, such as (a) making service referrals based on the fit between youths' criminogenic needs and services, and (b) assigning levels of supervision based on youths' level of risk. There was a shift in attention to more evidence-based dynamic risk factors. These changes occurred regardless of which RNA tool was used. Juvenile justice agencies are encouraged to adopt an evidence-based RNA tool using a sound implementation model in order to meet the objectives of the JJDPA and RNR practices. Benefits and barriers to adoption of RNA tools by juvenile probation departments are discussed. KW: Juvenile justice; Juvenile delinquency; Language: en

Short and long-term prediction of recidivism using the youth level of service/case management inventory in a sample of serious young offenders.

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.

Elucidating the treatment needs of gang‐affiliated youth offenders

PurposeGang affiliation is strongly associated with youth crime. Although gang prevention, intervention and suppression programmes have been used to reduce affiliation and manage youth gang‐related activities, the effectiveness of these approaches is questionable. Further, comprehensive programmes supporting disengagement from gangs that also address the actual criminal behaviours of gang‐affiliated youth are rare. Arguably, these are necessary if the goal of intervention is to reduce criminal behaviour and support disengagement from gangs. This paper aims to address these issues.Design/methodology/approachThis study sought to elucidate the criminogenic needs of gang‐ and nongang‐affiliated youth offenders (n=165) using two commonly used risk/need assessment instruments, the structured assessment of violence risk in youth (SAVRY) and the youth level of service/case management inventory (YLS/CMI).FindingsThe results revealed that gang‐ and nongang‐affiliated youth offenders had similar criminogenic need profiles except for one difference on an item measuring peer delinquency.Practical implicationsGang‐affiliated youth offenders have comparable criminogenic needs to other youth offenders. These needs require intervention if a reduction in crime is desired, and since gang‐affiliated youth offenders are more likely to re‐offend than those that are nongang‐affiliated, these results also suggest that there may be additional needs, beyond those assessed by the SAVRY and YLS/CMI, which should be investigated and considered in rehabilitation programmes.Originality/valueFew studies have directly compared the risk and needs profiles between gang‐ and nongang‐affiliated youth offenders using standardised risk assessment measures; this study may be relevant to professionals working in the juvenile justice and offender rehabilitation arenas.

Multilevel Recidivism Prediction

Risk assessments such as the Youth Level of Service/Case Management Inventory (YLS/CMI) that predict delinquency outcomes based on proximal risk factors may benefit from an incorporation of distal risk factors in their prediction models. This study utilized a juvenile probationer sample and block group SES data in exploring the differential predictive validity of the YLS/CMI with youth of similar person-centered risk levels from different criminogenic neighborhood types. The study entailed an exploratory factor analysis of block group socioeconomic variables, which were used in a cluster analysis to create criminogenic neighborhood typology system. Hierarchical logistic regression was used to analyze the relationship among recidivism (Level 1), risk score (Level 1), neighborhood SES factors (Level 2), and neighborhood types (Level 2). Significant interactions were found across levels among variables, suggesting the risk—recidivism relationship was moderated by neighborhood socioeconomic ecology. Implications for practice and policy are discussed.

Comparative Analyses of the YLS/CMI, SAVRY, and PCL:YV in Adolescent Offenders: A 10-year Follow-Up Into Adulthood

A growing body of research has been dedicated to developing adolescent risk assessment instruments, but much of this research has been limited to short-term tests of predictive validity. The current study examined the predictive and incremental validity of the Youth Level of Service/ Case Management Inventory (YLS/CMI), Structured Assessment of Violence Risk in Youth (SAVRY), and Psychopathy Checklist: Youth Version (PCL:YV) in adolescent offenders over a mean 10-year follow-up period. Each instrument predicted general recidivism with moderate- (YLS/CMI area under the curve [AUC] = .66) -to-large effect sizes (SAVRY AUC = .74; PCL:YV AUC = .79). However, there was variation in predictive validity across types of recidivism, and all three instruments were better at predicting recidivism in males than females. SAVRY total also demonstrated incremental validity over its structured professional judgment of risk. Clinical implications and future directions for youth risk assessment are discussed.

Predictive validity of the youth level of service/case management inventory in custody sample in England

The Youth Level of Service/Case Management Inventory (YLS/CMI) is widely used in the United Kingdom, yet there have been no validation studies in England and Wales. This prospective study aimed to explore the predictive ability of the YLS/CMI in sample of 135 male adolescents with conduct problems in the absence of major Axis I pathology. Participants were assessed in custody and followed up 12 months post release. Outcome data on recidivism were based on Home Office records. YLS/CMI total score was a modest predictor of non-violent and any recidivism but the YLS/CMI risk classification showed greater predictive power. Participants classified at different risk levels showed differences in the frequency and time-to recidivism. Those rated as very high risk were 10.7 times more likely to re-offend sooner and 94% of the very high-risk group did re-offend over the follow-up period. Data are discussed in relation to implications for treatment planning and risk management.
