Comparison of Two ASI-Based Standardized Patient Placement Approaches

Abstract

This study evaluated the predictive validity of two automated approaches based on the Addiction Severity Index (ASI) to patient placement criteria. Patients (N = 2,429) in 78 substance abuse treatment programs completed an ASI at intake and were assigned a treatment modality based on availability and clinical considerations. Treatment completion and self-reported abstinence 6 months post-discharge were collected. Two placement approaches were developed using ASI summary score cut points or problem-specific algorithms from ASI items. Both approaches showed evidence of predictive validity. Given the ASI's widespread use in community programs, evidence is provided in support of its ability to inform clinical judgment and implementation of standardized placement.
