A two-arm RCT will be conducted to test the efficacy of Women SHINE, a web-based trauma-informed peer navigation-social support intervention (Figure 2). A total of 360 women living with HIV/AIDS (WLHA) with a history of adulthood interpersonal violence who have been prescribed ART but are non-adherent (< 90% ART adherent in the last 4 weeks) will be enrolled in the study. WLHA will be randomized (1:1) into one of the following conditions: 1) Women SHINE intervention arm (n=180) or 2) Control arm (n=180). The Women SHINE intervention arm will receive a four-month intervention including peer navigator (PN) one-on-one sessions, phone/text-based check-ins, 7 psychoeducation weekly support group sessions (120 mins.) co-facilitated by a licensed therapist and PN, and access to a static website with resources for HIV care, interpersonal violence, trauma, mental health, and substance use. The control arm will receive one group session (60 mins.) on self-care and well-being and access to the aforementioned website with resources. Women will complete a video-based survey and mailed hair sample self-collection at baseline, 4-, 8-, and 12-months post-randomization, to evaluate improvements in ART adherence (Aim 1), emotion regulation, and PTSD symptoms (Aim 2). Investigators will examine the mediating effect of individual (retention in HIV care, coping self-efficacy, social support, ancillary support services use) and socio-structural (stigma, medical mistrust) mechanisms of change on the efficacy of Women SHINE (Aim 3).
In the US, women living with HIV/AIDS (WLHA) are less likely to be adherent to antiretroviral therapy (ART) and virally suppressed compared to men living with HIV/AIDS. Concurrently, WLHA experience high rates of interpersonal violence - physical, sexual, and/or psychological abuse in childhood or adulthood - which often results in trauma (e.g., post-traumatic stress disorder [PTSD]) and other adverse mental health, further contributing to ART non-adherence. Additionally, the confluence of syndemic or co-occurring adverse mental health, substance use, and socio-structural factors (e.g., HIV stigma, medical mistrust) further contribute to poor HIV outcomes. Social support through peer navigation and networks has been shown to counter these effects and improve HIV outcomes among WLHA. Likewise, psychoeducation addressing affective distress to improve mood and emotion management and relationship skills has been shown to reduce PTSD and depression. However, limited resources at HIV service agencies combined with socio-structural barriers (e.g., social isolation, lack of transportation) impede the potential effectiveness of in-person peer navigation. A scalable and sustainable solution is the use of technology in the form of web-based video interaction. Building on these promising pilot findings, investigators propose to conduct a randomized clinical trial of Women SHINE (new name) to improve ART adherence among WLHA affected by interpersonal violence in California. Participants will be randomized to either: a) the intervention arm (n=180) where they will receive a 4-month program comprised of video-based peer navigation support via one-on-one sessions, 7 psychoeducation weekly support group sessions, and access to a static Women SHINE website with statewide resources for HIV care, interpersonal violence, trauma, mental health, and substance use; or b) the control arm (n=180) where they will receive a single group session on self-care and well-being, with access to the static Women SHINE website. Women will complete video-based survey assessments and mailed hair sample self-collection at baseline, 4-, 8-, and 12-months post-randomization. Compared to the control arm, investigators will determine if Women SHINE is associated with improvements in ART adherence (Aim 1) and PTSD symptoms and emotion regulation (Aim 2). Investigators will also examine individual (e.g., self-efficacy for coping, social support networks) and socio-structural (e.g., HIV stigma, medical mistrust) mechanisms of change in the efficacy of Women SHINE (Aim 3). If efficacious, investigators will conduct subsequent research to determine effective and feasible methods for intervention implementation nationwide to improve HIV outcomes among WLHA.
