Optimizing Youth Risk Assessment Performance: Development of the Modified Positive Achievement Change Tool in Washington State

“…For a given model, if a scale was not found to be predictive of recidivism, the model was run a second time with the individual items (deconstructing the scale) included in place of the combined metric. While every scale identified in the PCA was not found to be predictive, many offered underlying evidence to support a variety of variable combinations (see Hamilton, Kigerl, Mei, Routh, & Kowalski, 2018). 3…”

“… 3. Detailed information pertaining to the principle component analysis (PCA) methods and results can be found in Appendix III of the technical report completed for the Washington State Juvenile Court Administrators (WSJCAs) (see Hamilton, Kigerl, Mei, Routh, & Kowalski, 2018). …”

“… 8. Item/response weights and model coefficients can be found in Hamilton et al’s (2018) technical report. The initial version of the Modified Positive Achievement Change Tool (M-PACT) produced separate models for Property and Drug outcomes, which were later combined to create the nonviolent models presented here. …”

“…This set of factors can then be crossvalidated on new samples and the model's predictivity, validity, and reliability compared to available "gold standard" recidivism risk/needs assessment tools, including the Level of Service/Case Management Inventory (LS/CMI; Andrews et al, 2004), the Federal Post-Conviction Risk Assessment (PCRA; Johnson et al, 2011), and the Ohio Risk Assessment System (ORAS; Latessa et al, 2009). For a review of the most commonly used and bestvalidated recidivism risk/needs assessment tools, see the handbook by Hamilton et al (2018). To date, none of these instruments has been validated on adult offenders diagnosed with FASD, although promising preliminary findings have been discovered for the use of risk/needs assessment tools with young offenders with FASD (McLachlan et al, 2018).…”

“…In addition to stressing the importance of assessors being cognizant of FASD in the populations they serve, staff need to be made aware of the various recommendations to best factor this information into their practices. Studies have found that providing "booster" sessions every 2-3 years following an initial training can be helpful in knowledge retention (Hamilton et al, 2018). These boosters may involve practice examples such as showing participants a recorded mock interview, allowing them to evaluate the interviewee, and then reviewing their evaluations.…”
