The Influence of Acculturation on Substance Use Behaviors among Latina Sexual Minority Women: The Mediating Role of Discrimination

Background: A large body of work has demonstrated that sexual minority women have elevated rates of substance use morbidity, as compared with heterosexual women, and that this might be especially true for women of color. Objectives: This study examines the influence of acculturation and discrimination on substance use among Latina sexual minority women. Methods: Data were collected from 2007 to 2008 as part of a larger community-based survey in the greater Chicago area. Scales measured discrimination, acculturation, and substance use. Structural equation modeling validated scales and examined their relationships, which were further described via mediation analysis. Results: Increased acculturation leads to substance use and this relationship is partially mediated by discrimination (Sobel test = 2.10; p < .05). Conclusions/Importance: Implications of these findings and directions for future research are discussed. Funding was provided by several women's and public health organizations.
