Efficacy of the substance abuse subtle screening inventory-3 (SASSI-3) in identifying substance dependence disorders in clinical settings

This article presents analyses on psychometric properties of a recent revision of the Substance Abuse Subtle Screening Inventory (SASSI-3). Participants were 772 individuals from a range of clinical settings who were independently diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-II-R]; American Psychiatric Association [APA], 1987) or DSM-IV (APA, 1994) criteria regarding the presence or absence of a substance-dependence disorder. A development sample (n = 391) was used to formulate SASSI-3 decision rules that yielded 95% agreement with clinical diagnoses of substance dependence. Correspondence with the criterion variable was shown to be 97% in a cross-validation sample (n = 381) from the same clinical settings. Convergent relations were demonstrated with a variety of other indexes of substance misuse, including clinical assessments of substance abuse history, alcohol and drug-related arrests, self-reported use of illicit drugs, and other instruments designed to screen for substance misuse. Further, logistic regression analyses indicated no significant differences in the overall accuracy of the SASSI-3 as a function of respondents' demographic characteristics or clinical ratings of respondents' level of adjustment and functioning (Global Assessment of Functioning ratings; APA, 1987, 1994).
