Abstract
OBJECTIVE: People experiencing homelessness are disproportionately impacted by alcohol-related harm. Racially minoritized groups are disproportionately represented in the homeless population and are likewise disproportionately impacted by alcohol-related harm. Most alcohol outcome measures have not been adequately psychometrically studied in this marginalized population and across racial groups. This study documents psychometric properties, including measurement invariance, reliability, and convergent validity, of a measure of alcohol-related harm, the Short Inventory of Problems (SIP-2R), across Black, North American Indigenous (NAI), and White adults experiencing homelessness and alcohol use disorder (AUD). METHOD: = 493; NAI = 205, Black = 125, and White = 163) were included in this psychometric study of the 15-item SIP-2R. RESULTS: < .001. CONCLUSION: This study provided support for the internal consistency, convergent validity, and cross-group measurement equivalence of the SIP-2R for NAI, Black, and White adults experiencing homelessness with AUD.
