A proof of concept study of promotive, mixed, and risk effects using the SAVRY assessment tool items with youth with sexual offenses.

Abstract

There is currently a lack of consensus about the nature of strengths in forensic assessments. With 273 justice-involved male youth and a fixed 3-year follow-up, this study adopted the approach of Farrington and colleagues to investigating the nature of associations between trichotomized variables, representing risks and strengths, and outcomes using pairs of odds ratios (ORs) and percentage point changes from base rates. Items from the Structured Assessment of Violence Risk in Youth (SAVRY), a structured professional judgment tool used to assess risk and protective factors in justice-involved youth, were employed for this purpose. In the literature, the accuracy of SAVRY summed totals for its Risk Factor item sets (each item rated using a trichotomy) has been generally in the moderate range in predicting future violence. But the total for its summed Protective Factor items (each rated using a dichotomy) has been less consistently encouraging. In this study, contrary to their labels, the majority of SAVRY Risk and Protective Factors (rated using trichotomies) exerted a risk effect at one end of their trichotomy (risk item ratings of 2, protective item ratings of 0) and a promotive effect at the other end (risk item ratings of 0, protective factor ratings of 2) for a new violent (including sexual) offense and any new offense. Subsets of items conservatively weighted using ORs (capturing risk and strength) were statistically significantly more accurate in predicting outcomes than their originally rated counterpart subsets. Implications for understanding the nature of strengths and for applied assessment practices are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
