BACKGROUND: The Inventory of Drug Use Consequences (InDUC) ( [1] ) is a 50-item measure that evaluates lifetime and recent consequences of substance use. OBJECTIVES: This study examined the psychometric properties of a modified version of the Inventory of Drug Use Consequences (InDUC-M) in individuals with serious and persistent mental illness (SPMI) and co-occurring substance use disorders (SUDs). METHODS: We examined self-reported consequences in the sample, evaluated internal consistency, identified items for a brief form of the InDUC-M, and explored relationships with indicators of substance use severity. RESULTS: InDUC-M Lifetime and Recent subscales showed good internal consistency and were related to other measures of substance use and problems. A brief version of the InDUC-M Recent (SIP-M) showed excellent internal consistency and was highly correlated with both Lifetime and Recent subscales. CONCLUSION: The InDUC-M and the SIP-M performed well in individuals with SPMI and SUDs. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Overall, these findings are a useful first step in determining the utility of the InDUC-M in people with SPMI and SUDs.
