Specifications include, but are not limited to: The STATE is seeking a PROVIDER to study data on all assessments conducted since implementation of the YASI assessment tool. A series of fixed follow-up samples (e.g., 12 months, 2 years, 3 years, etc.) will need to be assembled to evaluate the predictive validity of the YASI scores. Both Pre-Screen (Risk and Protective Factors) and Full Assessments overall scores and domains (Overall Dynamic Risk, Overall Dynamic Protective Factors) must be included. The study must assess the predictive validity of the assessment model using the “Area Under the Curve” as the index of predictive accuracy. Predictive Validity for multiple recidivism measures, as available, must be included in the study. The study must also examine the performance of the current cut-points for overall Pre-Screen and Full Assessment scores with the potential for customizing the cut-points for the STATE.
