Summary View help for Summary
This study sought to develop a risk assessment instrument to be used in the placement of adjudicated juveniles and determination of outcomes for juvenile probationers. The following research questions served as a guide in developing the risk assessment instrument: (1) Does the instrument measure what it purports to measure? (2) Do similar cases receive similar recommendations for placement services? (3) Is the instrument fair to dissimilar groups? (4) Is the instrument useful to practitioners? and (5) Will the instrument be simple to implement? The goal of the new risk assessment instrument was to address the relative risk of recidivism without taking into account the severity of the current offense. In order to develop a new risk assessment instrument, researchers adapted a pre-existing instrument that had been used and validated with juvenile probationers in California. The new instrument was used to evaluate youths for three measures of recidivism: intake actions, petitions filed, and petitions sustained through one year after the placement decisions were made. The sample of youths was comprised of those who in 1996 had received either a field supervision or a placement order as a disposition. The instrument measured age at first finding, prior criminal behavior, institutional commitments or placement of 30 consecutive days or more, drug/chemical use, alcohol use, parental skills, school disciplinary problems, and peer relationships.

Study Purpose View help for Study Purpose
This study was undertaken as part of a larger project whereby the Alameda County Probation Department in California sought to improve the effectiveness and efficiency of its Juvenile Services Division by implementing a system-wide classification and placement system to address the public concern for safety and effectiveness in dealing with juvenile crimes. The purpose of this study was to develop a risk assessment instrument to be used in the placement of adjudicated juveniles and determination of outcomes for juvenile probationers. The following research questions served as a guide in developing the risk assessment instrument: (1) Does the instrument measure what it purports to measure?

Study Design View help for Study Design
In order to develop a new risk assessment instrument, researchers adapted a pre-existing instrument that had been used and validated on juvenile probationers in California. The goal of the new risk assessment instrument was to address the relative risk of recidivism without taking into account the severity of the current offense. Nine probation officers consisting of deputies and supervisors were trained using the draft of the new instrument. The instrument was used to evaluate youths for three measures of recidivism: intake actions, petitions filed, and petitions sustained through one year after the placements decisions were made. The sample of youths was comprised of those who in 1996 had received either a field supervision or a placement order as a disposition. Field supervision refers to a sanction in which the youth was maintained and supervised in the community with the aid of weekend programming. Placement refers to any sanction in which the youth was placed out of home (e.g., a group home, camp, or residential treatment).
