Measurement invariance and other psychometric properties of the Short Inventory of Problems (SIP-2R) across racial groups in adults experiencing homelessness and alcohol use disorder.

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: Adults experiencing homelessness and AUD who had participated in one of two randomized controlled trials of harm-reduction treatment (N = 493; NAI = 205, Black = 125, and White = 163) were included in this psychometric study of the 15-item SIP-2R. Results: Multigroup confirmatory factor analysis (MGCFA) indicated that a model comprising one general alcohol-related harm factor overarching five factors, showed close fit and partial scalar invariance, χ²(329, N = 493) = 624.902, p
