Risk Assessment in Juvenile and Young Adult Offenders: Predictive Validity of the SAVRY and SAPROF-YV.

ABSTRACT: Most juvenile risk assessment tools heavily rely on a risk-focused approach. Less attention has been devoted to protective factors. This study examines the predictive validity of protective factors in addition to risk factors, and developmental differences in psychometric properties of juvenile risk assessment. For a national Dutch sample of 354 juvenile and young adult offenders (16-26 years) risk and protective factors were retrospectively assessed at discharge from seven juvenile justice institutions, using the Structured Assessment of Violence Risk in Youth (SAVRY) and Structured Assessment of Protective Factors for violence risk - Youth Version (SAPROF-YV). Results show moderate validity for both tools predicting general, violent, and nonviolent offending at different follow-up times. The SAPROF-YV provided incremental predictive validity over the SAVRY, and predictive validity was stronger for younger offenders. Evidently both the SAVRY and SAPROF-YV seem valid tools for the assessment of recidivism risk in juvenile and young adult offenders. Results highlight the importance of protective factors, especially in juvenile offenders, emphasizing the need for a balanced risk assessment.

Project description:ImportanceThe ability of present-day etiologic stroke classification systems to generate subtypes with discrete stroke characteristics is not known.ObjectiveTo test the hypothesis that etiologic stroke subtyping identifies different disease processes that can be recognized through their different clinical courses.Design, setting, and participantsWe performed a head-to-head evaluation of the ability of the Causative Classification of Stroke (CCS), Trial of Org 10172 in Acute Stroke Treatment (TOAST), and ASCO (A for atherosclerosis, S for small-vessel disease, C for cardiac source, and O for other cause) classification systems to generate etiologic subtypes with different clinical, imaging, and prognostic characteristics in 1816 patients with ischemic stroke. This study included 2 cohorts recruited at separate periods; the first cohort was recruited between April 2003 and June 2006 and the second between June 2009 and December 2011. Data analysis was performed between June 2014 and May 2016.Main outcomes and measuresSeparate teams of stroke-trained neurologists performed CCS, TOAST, and ASCO classifications based on information available at the time of hospital discharge. We assessed the association between etiologic subtypes and stroke characteristics by computing receiver operating characteristic curves for binary variables (90-day stroke recurrence and 90-day mortality) and by calculating the ratio of between-category to within-category variability from the analysis of variance for continuous variables (admission National Institutes of Health Stroke Scale score and acute infarct volume).ResultsAmong the 1816 patients included, the median age was 70 years (interquartile range, 58-80 years) (830 women [46%]). The classification systems differed in their ability to assign stroke etiologies into known subtypes; the size of the undetermined category was 33% by CCS, 53% by TOAST, and 42% by ASCO (P < .001 for all binary comparisons). All systems provided significant discrimination for the validation variables tested. For the primary validation variable (90-day recurrence), the area under the receiver operating characteristic curve was 0.71 (95% CI, 0.66-0.75) for CCS, 0.61 (95% CI, 0.56-0.67) for TOAST, and 0.66 (95% CI, 0.60-0.71) for ASCO (P = .01 for CCS vs ASCO; P < .001 for CCS vs TOAST; P = .13 for ASCO vs TOAST). The classification systems exhibited similar discrimination for 90-day mortality. For admission National Institutes of Health Stroke Scale score and acute infarct volume, CCS generated more distinct subtypes with higher between-category to within-category variability than TOAST and ASCO.Conclusions and relevanceOur findings suggest that the major etiologic stroke subtypes are distinct categories with different stroke characteristics irrespective of the classification system used to identify them. We further show that CCS generates discrete etiologic categories with more diverse clinical, imaging, and prognostic characteristics than either TOAST or ASCO.
