This article describes the development and reliability and validity testing of the Addiction Severity Assessment Tool (ASAT), a brief, 27-item multidimensional self-report measure of problem severity in daily functioning, relational functioning, dysphoric states, dependence severity, recovery skill/self-efficacy, and existential factors for adult substance abuse clients. Items generated for an Alpha version were conceptually and empirically evaluated. A Beta version underwent further empirical evaluation and item selection. Cross validation of the final version examined internal consistency, test-retest reliability, factor structure, and convergent/discriminant and known groups validity. Sensitivity to change was evaluated in a 3-month outcome study. Clients were recruited from inpatient, outpatient and residential substance abuse treatment centers, and a sample of 238 nonpatients were also recruited from community groups. The Beta version was tested with 201 clients, and cross validation involved 242 clients. Well-known standardized, self-report and interview-based comparison measures were used to test convergent/discriminant validity of the ASAT. Reliability coefficients for the six ASAT domains were acceptable. Reasonable convergent/discriminant and known groups, construct validity were demonstrated, along with sensitivity to change of the domain scale scores. The ASAT appears to comprise a useful new tool for assessing clinical outcomes of adult clients in substance abuse treatment.
