Predictive and Convergent Validity of the Youth Assessment and Screening Instrument in a Sample of Male and Female Justice

Sufficient evidence exists that gender should and does matter in offender management. This study examined the predictive validity of risk and strength factors extracted from the Youth Assessment and Screening Instrument (YASI) and the Youth Level of Service/Case Management Inventory (YLS/CMI) in a sample of 254 justice-involved youth (148 males, 106 females) from Ontario, Canada. Overall, total risk scores from both measures predicted recidivism (area under receiver operator characteristic curve [AUCs] = .62-.70). Domain-level analyses illustrated that criminal attitudes and associates (scored as risks or protective/strengths) were among the strongest predictors of recidivism in both genders. The YASI demonstrated strong convergent validity with the YLS/CMI. The results support the YASI and the YLS/CMI as viable risk assessment measures for justice-involved male and female youth. Given that the YASI includes both gender neutral and gender responsive items, it may be a particularly good choice for use with justice-involved females
