RESUMO
Racial/ethnic minority status and physical abuse history are risk factors for higher mortality rates and lower adherence to antiretroviral therapy (ART) in women living with HIV (WLWH) in the United States. The current study tested the hypotheses that minority status and physical abuse history might lead women to silence the self (minimize and hide thoughts and feelings in order to avoid relational conflict, loss, and/or abuse) as measured by the Silencing the Self Scale (STSS), and that STSS might mediate and moderate relationships of physical abuse and racial/ethnic minority status with ART adherence. Divided Self (DS; acting in ways inconsistent with inner thoughts and feelings), an STSS subscale, was targeted for study along with the total STSS score. Participants were 513 women from the U.S. Women's Interagency HIV Study (M age = 46; 387, 75%, Black; 66, 13%, Hispanic; 60, 12%, White). Multiple logistic regressions indicated that across all racial/ethnic groups, physical abuse history related to higher DS and lower adherence. DS significantly mediated relationships between abuse and adherence. Compared to White women, Black women demonstrated worse ART adherence, but had lower total STSS. Racial/ethnic minority women and women with a physical abuse history who had higher DS had lower adherence than other groups. Results indicate that being a racial/ethnic minority or having a history of physical abuse may increase vulnerability to the deleterious effects of DS on ART adherence, findings that can help inform interventions to decrease health disparities in WLWH.
