Discrimination and alcohol problems among heavy drinking HIV-positive men who have sex with men: The buffering effect of a brief Motivational Intervention to reduce alcohol use

Abstract

Introduction: Heavy alcohol use negatively impacts health outcomes among people with HIV and is especially prevalent among men who have sex with men (MSM). Alcohol problems among MSM with HIV may occur, in part, due to increased stress caused by experiences of identity-based discrimination, such as heterosexism, HIV stigma, and racism. The current study examined (a) whether MSM with HIV who experience greater identity-based discrimination reported higher levels of alcohol problems over time in the absence of alcohol intervention, and (b) whether motivational interviewing (MI) to reduce alcohol use would attenuate the effects of discrimination on alcohol problems.

Methods: Data came from a clinical trial in which MSM with HIV were randomized into brief MI for alcohol harm reduction [n = 89] or an HIV treatment as usual assessment only control [TAU; n = 91]. Alcohol use and problems were assessed at baseline, 3, 6, and 12 months.

Results: Generalized Estimating Equations found a significant interaction between MI and baseline identity-based discrimination, such that in those not receiving MI, discrimination prospectively predicted alcohol problems over time (B = 0.065, SE = 0.018, p < .001, 95% Wald CI [.030- 0.100]). In those receiving MI, discrimination did not have an effect (B = - 0.002, SE = 0.131, p = .987, 95% Wald CI [- 0.258 to 0.254]).

Conclusions: Even without explicitly targeting experiences of identity-based discrimination, a person-centered intervention, like MI, appears to mitigate the negative impact of identity-based discrimination on alcohol-related problems.
