The Effects of Changes in Dynamic Risk on Reoffending among Serious Juvenile Offenders Returning from Residential Placement

This study examines whether changes in dynamic risk during juvenile justice long-term residential placement affect recidivism. Advancing the work of prior dynamic risk change analyses, we examine a large sample of 11,891 male and 1930 female juvenile offenders while taking methodological steps to ensure successful and non-successful youth (in terms of recidivism) are (statistically) identical at admission. Specifically, we employ propensity score matching on residential placement youth who recidivate post-release and non-recidivists on static risk factors and initial dynamic risk scores assessed at admission to residential placement. Post-matching, changes in dynamic risk factors from initial assessment at admission to exit assessment at release are examined with a focus on whether those changes distinguish recidivists from non-recidivists. Separate analyses are conducted for male and female juveniles. Results indicate that changes in dynamic risk do affect recidivism likelihood, but that different factors matter for males and females. These sex-specific models allow for distinct policy recommendations.
