title: Examination of the inventory of drug use consequences with individuals with serious and persistent mental illness and co-occurring substance use disorders.
abstract: BACKGROUND
  The Inventory of Drug Use Consequences (InDUC) ( [1] ) is a 50-item measure that evaluates lifetime and recent consequences of substance use.
  
  
  OBJECTIVE
  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.
  
  
  CONCLUSIONS
  The InDUC-M and the SIP-M performed well in individuals with SPMI and SUDs.
  
  
  CONCLUSIONS
  Overall, these findings are a useful first step in determining the utility of the InDUC-M in people with SPMI and SUDs.
