Supplemental Material for Pretrial Risk Assessment Validation Research: Range Restriction and Attenuation of Predictive Validity Estimates

Juvenile court practitioners and researchers have recently gained interest in evaluating internal and external strengths, or protective factors. Some scholars assert that incorporating measures of strengths into the risk assessment process can increase the accuracy of identifying odds of recidivating. Relatively few juvenile risk assessment validation studies have evaluated the predictive validity of strengths. This study employed a diverse sample ( N = 278) of juveniles under supervision in a Midwestern court. The Protective Factors for Reducing Juvenile Reoffending (PFRJR) significantly predicted recidivism for the total sample, males, and White youth. There was no evidence of differential predictive validity across gender; however, strengths predicted differently across race/ethnicity. Strengths did not increase the amount of variance explained in recidivism after accounting for the variance explained by risk factor scores. Findings contribute to the paucity of validation studies that investigated the differential and incremental predictive validity of strengths.

Domestic Violence Screening

This study seeks to determine the concurrent and predictive validity of a dual risk assessment protocol. It combines the risk of persistence in intimate partner violence (IPV) measured via the Domestic Violence Screening Instrument–Revised (DVSI-R) with supplemental items from the Danger Risk Assessment (DRA) bearing on the risk of potential lethality. We further test whether this assessment protocol reproduces disparities by race and ethnicity found in the larger population. Using a sample of 4,665 IPV male defendants with a female victim, analyses support both types of criterion validity. The DRA risk score is associated with felony charges, incarceration at the initial arrest, and the frequency of subsequent dangerous behavior. Results also suggest minimal predictive bias or disparate impact by race and ethnicity. Incorporating supplemental items bearing on potential lethality risk adds important information concerning the risk management strategies of those involved in IPV.

Over Time

The Level of Service Inventory—Revised (LSI-R) is an actuarially derived risk assessment instrument with a demonstrated reputation and record of supportive research. It has shown predictive validity on several offender populations. Although a significant literature has emerged on the validity and use of the LSI-R, no research has specifically examined change scores or the dynamics of reassessment and its importance with respect to case management. Flores, Lowenkamp, Holsinger, and Latessa and Lowenkamp and Bechtel, among others, specifically identify the importance and need to examine LSI-R reassessment scores. The present study uses a sample of parolees ( N = 179) from various community corrections programs that were administered the LSI-R at two different times. Results indicate that both mean composite and subcomponent LSI-R scores statistically significantly decreased between Time 1 and Time 2. The practical, theoretical, and policy implications of these results are discussed.
