Abstract
Introduction
Worldwide, women comprised 51 percent of all adults living with HIV in 2015, with the incidence of HIV among women continuing to increase since the beginning of the HIV epidemic (
With improvements in access to HIV treatment and medications themselves, women living with HIV (WLWH) live increasingly longer and healthier lives (Teeraananchai et al., 2017). Growing attention has focused on understanding how to support WLWH’s positive emotional, psychological and social-cognitive well-being. High prevalence of psychiatric conditions including depression (Morrison et al., 2002), anxiety, and post-traumatic stress disorder (e.g. 5-fold as high rates in the United States (Machtinger et al., 2012), have been reported among WLWH. WLWH experience high levels of trauma across their lifetimes both prior to and following their HIV diagnoses, including physical, sexual and verbal/emotional abuse in both childhood and adulthood (LeGrand et al., 2015), as well as HIV discrimination and stigma (Logie et al., 2018). In Canada, Indigenous women are overrepresented among WLWH, and continue to experience ongoing and multi-generational mental health, quality of life and well-being effects related to the trauma of settler colonialism and residential schools (Benoit et al., 2016). Suicide ideation and attempts, isolation, limited social support, coping challenges, substance use, reduced medication self-efficacy and HIV medication adherence challenges are common for women following an HIV diagnosis (Machtinger et al., 2012).
Some of these markers of emotional, psychological and social-cognitive well-being have been found to have particularly strong direct associations with HIV treatment and care outcomes. Depression and depressive symptoms are associated with HIV medication non-adherence in systematic reviews (Uthman et al., 2014). Medication self-efficacy, defined as the confidence that one has in taking medications as prescribed, is a social-cognitive measure that has been identified as important along the pathway to HIV outcomes including HIV medication adherence (Langebeek et al., 2014). Social support has been associated with adherence to medication regimes in a review and meta-analysis (Langebeek et al., 2014). Thus, in addition to being critical to investigate on their own in relation to women’s well-being, these outcomes can also play important roles in supporting women’s health related to living with HIV more broadly.
Multiple forms of HIV stigma have been identified as barriers to depression, social support, and medication self-efficacy. The effects of HIV stigma remain a global concern for WLWH and are deeply embedded within these relationships. HIV stigma has been associated with higher depression and reduced social support (Rueda et al., 2016), and reduced HIV medication self-efficacy (Sweeney and Vanable, 2016). HIV stigma has also been associated with HIV treatment and care outcomes including reduced adherence to HIV medication (Sweeney and Vanable, 2016), Many mechanisms of HIV stigma have been characterized, and include anticipated stigma—referring to fear or anticipation of mistreatment and rejection following disclosure of one’s HIV positive status; internalized stigma—acceptance of negative feelings and societal beliefs about persons living with HIV (PLWH), and perceived stigma—awareness of negative beliefs and values toward PLWH in one’s society and community (Turan et al., 2017). Enacted stigma refers to acts of mistreatment due to HIV status, and can include discrimination (Turan et al., 2017).
Growing but very limited attention has been drawn to exploring the definitions and specific effects of two types of enacted stigma, including violence (e.g. verbal, physical) related to HIV status, and involuntary disclosure of HIV status/ HIV status disclosure without consent (Barreto, 2017; Duff et al., 2018). However, there is some evidence that these types of HIV stigma could have important impacts on other forms of HIV stigma as well as health and well-being outcomes for PLWH. While voluntary disclosure of HIV status has been shown to be positively correlated with social support (Loutfy et al., 2016), as well as quality of life (Loutfy et al., 2016), and reduced levels of depression or depressive symptoms among WLWH (Vyavaharkar et al., 2011), from a human rights perspective, it is imperative to recognize the potential and realized harms to women from disclosure (Obermeyer et al., 2011), particularly when disclosure is involuntary. These harms can include isolation, abandonment, other stigma, discrimination, and violence (Krüsi et al., 2018; Varga et al., 2006). No quantitative research to our knowledge has been conducted on relationships between HIV status disclosure without consent and important emotional, psychological, and social-cognitive well-being outcomes including depression, social support, or HIV medication self-efficacy; our research aims to fill this research gap.
We are also unaware of any studies that look at the relationship between verbal or physical violence perceived as being related to HIV status on these outcomes. Many studies with women (both living and not living with HIV) have found a relationship between violence and depression; for example, a meta-analysis of studies largely from the United States suggested an increased risk of major depressive disorder (2- to 3-fold), elevated depressive symptoms, and post-partum depression (1.5- to 2-fold increased odds) among women exposed to intimate partner violence relative to those not exposed (Beydoun et al., 2012). Recent trauma has been associated with having a detectable viral load (⩾75 copies/mm) and reduced self-reported antiretroviral use among cis and trans women (Machtinger et al., 2012), and gender-based violence against WLWH has been associated with reduced ART adherence in our study setting (Barreto, 2017). WLWH with a history of physical and sexual violence were significantly more likely to experience negative social and physical consequences following HIV disclosure (Gielen et al., 2000). Research with women suggests that experiences with intimate partner violence have been associated with lower perceived social support (Thompson et al., 2000). Among adolescents, violence has been associated with reduced peer status (Cook et al., 2010), as well as loss of friends/reduced social networks, with this relationship stronger among girls (Wallace and Ménard, 2017).
The factors through which these two rarely examined forms of enacted HIV stigma – HIV disclosure without consent and verbal/physical violence related to HIV status – act on emotional, psychological, and social-cognitive well-being outcomes is not well-understood. Previous research in our study setting has identified direct associations between disclosure of HIV status without consent and anticipated, enacted and perceived HIV stigma and between verbal and physical violence associated with HIV-positive status (“HIV-related violence”) and enacted, internalized, and perceived HIV stigma (Deering et al., 2019). The current study draws on this analysis and the literature to test a conceptual model using path analysis and investigate pathways from HIV disclosure without consent, HIV-related physical and verbal violence, and depression, social support, and HIV medication self-efficacy through mediators of other HIV-related stigma dimensions (other enacted, anticipated, internalized and perceived HIV stigma) among WLWH currently taking ART in Vancouver, Canada.
Methods
Study design and sampling
Data were drawn from 2 years of follow-up (four follow-up surveys) from a longitudinal community-based participatory open cohort of 325+ cis or trans WLWH who lived and/or accessed care in Metro Vancouver, Canada (2014-present; Sexual Health and HIV/AIDS: Women’s Longitudinal Needs Assessment “
Eligibility for SHAWNA includes being aged 14 or older and living and/or accessing HIV/AIDS services in Metro Vancouver. Various recruitment methods based on community-based research principles were used to recruit participants, including: self-referrals and referrals from HIV care providers, peer researchers, HIV/AIDS service organizations, and clinical outreach, including British Columbia’s primary referral center for WLWH (Oak Tree Clinic, based at BC Women’s Hospital; Kestler et al., 2018). Participants who have provided informed consent completed a semi-annual peer or community interviewer-administered questionnaire at baseline and 6-month follow-ups. The questionnaire covers social-demographics and structural vulnerability (e.g. experiences of violence, food insecurity, sex work, and drug use). Participants then respond to a second questionnaire, administered by a sexual health research nurse, that covers various aspects of sexual and reproductive health access and outcomes, as well as questions related to HIV status.
Participants also receive voluntary viral load/CD4 measurements and serology for sexually transmitted infections/Hepatitis C Virus serology by one of the project’s sexual health nurses. Participants are offered treatment by project nurses onsite, if needed, for symptomatic STI infections and Papanicolaou testing, regardless of enrolment in the study. At each visit, participants receive CA$50 remuneration for their time, travel, and expertise. SHAWNA holds ethical approval through Providence Health/University of British Columbia Research Ethics Board and BC Women’s Hospital.
Primary outcomes and explanatory variables in the path analysis model
All of the following variables were updated every 6 months (time-dependent), with the last 6 months (“recent”) as a reference point.
Our three main outcomes included: (1) depression (defined as a response of “yes” to a survey item asking if participants had been diagnosed with, had been treated for, or had received counseling for depression); (2) social support (defined as responding “a lot,” on a four-point response to the single survey item question “In general, how satisfied are you with the overall support you get from family/friends?”); and (3) and HIV medication self-efficacy (defined as responding “extremely sure” or “very sure,” on a four-point response to the single survey item question “How sure are you that you will be able to take all or most of your medication as directed?”).
Key explanatory variables in the path analysis model included HIV disclosure without consent (“outed” for being HIV-positive), and experiencing verbal or physical violence related to HIV status (being verbally or physically abused by a perpetrator because they knew or suspected the participant was HIV-positive). As in a previous study (Deering et al., 2019), HIV stigma was measured using nine questions from Wright’s shortened 10-item version (Wright et al., 2007) of Berger’s HIV-stigma scale (Berger et al., 2001). All stigma measures were considered continuous in path analysis. Table 1 presents the survey items that comprise each sub-scale.

Confounders in the multivariable path analysis model
Potential confounders for the final path analysis model included variables chosen based on a priori knowledge gathered from previous research and through ongoing discussions with peer researchers and members of our Community Stakeholder Advisory Board and Positive Women’s Advisory Board of WLWH. Socio-demographic variables included the following: age (continuously in years); duration since first diagnosed with HIV (continuously in years); identifying as a member of the sexual minority community (i.e. identifying as any of “gay,” “lesbian,” “bisexual,” “two-spirit,” “asexual,” “queer,” “other,” vs “straight”); identifying as a member of the gender minority community (identifying as any of “transgender,” “intersex,” “transexual,” “two-spirit,” “genderqueer,” “other,” vs “cisgender”); ethnicity (defined as Indigenous (First Nations, Métis, or Inuit), other visible/ethnic minority (African/Caribbean/Black/other minority), vs White); im/migrant to Canada (vs born in Canada); and education (graduated high school vs did not). With the exception of age, duration since HIV diagnosis, identifying as sexual minority and identifying as gender minority, all of the social-demographic variables listed were considered time-independent variables. The remaining variables were considered time-dependent and updated every 6 months. In addition to those just described, additional time-dependent variables examined as potential confounders included, in the last 6 months, being homeless, being in jail overnight or longer, sex work, injection drug use, and non-injection drug use.
Statistical analysis
Descriptive statistics were calculated for the overall sample of WLWH on ART and included frequencies and proportions for categorical variables, and measures of central tendencies (i.e. mean, medians, and interquartile ranges (IQRs)) for continuous data.
We used path analysis to investigate pathways from HIV disclosure without consent and HIV-related violence to depression, social support and HIV medication self-efficacy through mediators of other HIV-related stigma dimensions (other enacted from the HIV Stigma Scale, anticipated, internalized, and perceived HIV stigma). Path analysis is a form of multiple regression statistical analysis that is used to evaluate causal models by examining the relationships between one or several outcomes and two or more explanatory variables (Muthen et al., 1997). Path analysis was conducted using a weighted least-squares approach, with mean and variance adjustment to evaluate the hypothesized model (Muthen et al., 1997). We tested direct relationships between HIV disclosure without consent and physical/verbal violence associated with participant’s HIV-positive status, and three outcomes: depression, social support, and medication self-efficacy. We tested indirect relationships via four HIV-related stigma dimensions (other enacted from the HIV Stigma Scale, anticipated, internalized, and perceived HIV stigma). In the final models, we adjusted for the variables that were identified as confounders, described above. Standardized coefficients, standard errors, critical ratios, and

Results
Characteristics of participants
Overall, our study included 208 participants on ART who responded to ⩾1 follow-up survey during the 2 years of follow-up (max: four follow-up surveys). Table 1 presents characteristics of participants at their baseline survey. The median age of participants was 47 years (IQR: 40–53 years), with a median of 15 years (IQR: 9–21) since first diagnosed with HIV (Table 1). Indigenous women were over-represented in the sample (57.2%) relative to the BC population (5% in 2011), with 34.1 percent of participants reporting being White and 8.7 percent reporting another ethnicity. Overall, 38.9 percent of the sample reported identifying as sexual minority and 10.6 percent reported identifying as gender minority. In total, 6.3 percent reported having immigrated/migrated to Canada and 46.2 percent reported high school graduation. In the last 6 months, 10.1 percent reported being homeless, 23.6 percent reported sex work, and 44.2 percent and 47.1 percent reported injection and non-injection drug use, respectively (Table 1).
In the last 6 months, 13.5 percent of participants had their HIV status disclosed without their consent, and 9.6 percent reported physical or verbal violence related to their HIV status. With respect to outcomes, 19.2 percent of participants reported being diagnosed with, treated for, or received counseling for depression in the last 6 months, 56.3 percent reported being satisfied with their social support and 87.5 percent reported having HIV medication self-efficacy, as measured by feeling able to take ART as prescribed.
Path analysis
Path analysis was conducted to examine the direct and indirect effects of disclosure of HIV status without consent, physical, or verbal violence perceived as associated with HIV status and depression, social support, and HIV medication self-efficacy. After missing data were excluded, 194 participants with 464 observations over 2 years of follow-up were included in the final model. Final model fit indices suggest the model fit well to the data (χ2 = 2.856;

Discussion
Study findings suggested that two dimensions of HIV-related stigma play important mediating roles along the pathways to HIV medication self-efficacy and depression, and two important outcomes for PLWH that have emerged from the field of psychological health. Internalized HIV stigma mediated the relationship between physical/verbal violence associated with participant’s HIV status and reduced medication self-efficacy, while enacted HIV stigma mediated the relationship between HIV disclosure without consent and heightened depression. These results offer key insights into the psychological health and well-being of WLWH.
Our finding that internalized HIV stigma was a mediator in the relationship between HIV-related physical/verbal violence and reduced HIV medication self-efficacy provides insight into results from growing research indicating that trauma and violence is associated with reduced ART use, adherence to medication and viral load (Hatcher et al., 2015; Mugavero et al., 2006), including in our setting (Barreto, 2017). Relative to other psychological social-cognitive adherence variables, including attitudes and norms surrounding medication use, HIV medication self-efficacy has been identified as a critical determinant of adherence to medication (Langebeek et al., 2014). Medication self-efficacy describes an individual’s belief that they possess the ability to take medication (Schwarzer, 1992). In our study, as in many others, the
Physical violence and verbal abuse related to HIV status is a particularly harmful example of enacted HIV stigma and more research is needed to better understand how to intervene. In the shorter term, results suggest that individual and broader community interventions to reduce HIV stigma should recognize the risk of abuse and violence among WLWH. As with other groups who experience high rates of trauma (
Our results suggest that other enacted HIV stigma was a mediator in the relationship between HIV status disclosure without consent and depression, a key measure of psychological well-being. Since enacted HIV stigma (including discrimination) reflects discriminatory societal views of HIV that are translated into actions (Earnshaw et al., 2013), interventions tailored for and with WLWH to address mental health and counter enacted HIV stigma could use approaches that aim to mobilize social change and address HIV stigma on a community level (Prinsloo et al., 2017). On an intrapersonal level, support in building resilient coping skills could help women develop strategies to reduce the personal and emotional impact caused by the negative stigmatizing actions of others (Logie et al., 2013). Higher resilience has also been associated with reduced depression symptoms among WLWH, alongside other factors that could act along the pathway from internalized HIV stigma to depression (e.g. self-efficacy, self-esteem; Dale et al., 2019). Among many different populations in a systematic review, psychological resilience interventions based on a combination of cognitive-behavioral therapy and mindfulness techniques had a positive impact on individual resilience; more interventions should be tailored by and with WLWH (Joyce et al., 2018). Results also highlight the importance of eliminating situations where women may have their HIV status disclosed involuntarily and without their consent as an approach to addressing women’s mental health. It is critical that medical information of WLWH remain confidential, including in healthcare settings, where health professionals have a duty of confidentiality toward clients/patients. Protection of privacy is a fundamental human right and WLWH ought to be able to rely on their health information remaining private, especially when accessing health services and because disclosure of medical information relating to HIV can have uniquely negative consequences for individuals living with HIV relative to other health conditions. Continuing to work toward ensuring women’s privacy can help reduce opportunities for non-consensual disclosure of HIV status. Furthermore, given the potential benefits of safe HIV disclosure on women’s health and well-being, future research should investigate how interventions to support safe disclosure can be designed and evaluated to minimize the impact of disclosure on enacted HIV stigma (Kennedy et al., 2015). Research into how Canada’s punitive HIV disclosure laws promote HIV disclosure without consent, stigma and violence and the benefits of repealing such laws, should be continued and supported (Krüsi et al., 2018).
This study had several limitations as well as strengths. Our study’s smaller sample size may not provide power to detect some associations. However, because we are able to make use of multiple measurements over time in our longitudinal study approach, effective sample size is increased. Our study may not be representative of all WLWH in Metro Vancouver nor be generalizable to other settings. However, recruitment of study participants for SHAWNA is achieved by broad coverage of diverse AIDS Service Organizations and clinical settings by our peer research associates and clinical outreach, and we feel that our sample reflects the diversity of WLWH. Our study includes self-report data, which can be subject to social desirability bias, as well as recall bias (Althubaiti, 2016). However, we are confident in the training and experience of our peer, community, and clinical research interviewers in safe and supportive interview approaches to minimize these biases. We have investigated several key pathways out of many potential pathways to explore. While we considered depression, social support, and medication self-efficacy as separate outcomes, evidence suggests that these variables may be related in some study populations. For example, social support may be a mediator between HIV stigma and depression (Rao et al., 2012a); in supplementary analysis, we did not find social support to be a mediator between HIV stigma and depression, with the model with this pathway having worse fit than the model presented here. We are limited in our ability to detect causation, with reverse causation possible for some relationships (e.g. HIV stigma and depression).
HIV stigma dimensions emerged as important mediators in relationships between HIV disclosure without consent, violence and the wellbeing of WLWH, including depression and medication self-efficacy. Findings provide important insights for WLWH and implications for policy and practice, and can help improve the services and interventions, as well as promote the psychological quality of life and well-being for WLWH.
