Despite previous reports of biased Short Inventory of Problems (SIP) items across racial groups of men who have sex with men, the assumption of measurement invariance has not yet been tested across African-American and non-Latino White outpatient groups for the SIP-R. This study investigated measurement invariance properties of the Short Inventory of Problems-Revised (SIP-R) across racial groups. The sample included 195 African-American and 194 non-Latino White adult participants in a clinical trial investigating the effectiveness of motivational enhancement therapy in the National Institute on Drug Abuse Clinical Trials Network (CTN-0004).

The SIP-R demonstrated configural invariance and weak metric invariance between racial groups, suggesting conceptualizations of adverse consequences of substance use are equivalent across racial groups. However, the SIP-R also indicated partial strong/scalar and strict metric invariance; that is, four of the five constructs suggested differences in the normative levels of the items across racial groups.

Conclusions: This study is the first to report measurement equivalence properties of the SIP-R across racial groups. This study contributes to the growing literature on how substance abuse treatment researchers can ensure unbiased assessment when studying treatment outcomes across racial/ethnic minority groups. Since MI and MET techniques have become standard social work practice in substance abuse treatment settings, the SIP-R is expected to continue to be one of the most prominent outcome measures in practices involving motivational techniques. The current findings encourage the valid use of the SIP-R with samples of African-American and non-Latino White adult outpatients to validly examine treatment outcomes and test potential differential effectiveness of treatments across racial groups.
