RCT of an Intersectional Stigma Intervention to Sustain Viral Suppression Among Women Living With Serious Mental Illness and HIV in Botswana

The proposed project, "RCT of an intersectional stigma intervention to sustain viral suppression among women living with serious mental illness and HIV in Botswana," will test a culturally tailored stigma intervention among women with co-occurring serious mental illness (SMI) and HIV receiving inpatient treatment at Sbrana Psychiatric Hospital in Lobatse, Botswana, who are then discharged into outpatient care. The culturally tailored stigma intervention is based on our novel 'what matters most' (WMM) approach to target intersectional stigma. The investigators will also be conducting a family-level stigma intervention to test its efficacy at reducing family-level SMI and HIV stigma, and to test family-level stigma as a mechanism for change in VL among women. Lastly, the investigators will pilot a policymaker workshop intended to facilitate structural-level change.

Populations included in the study:

• Women with SMI and HIV,
• Family members, and
• Policymakers and other stakeholders

RESEARCH AIM 2.

The investigators propose a two-arm randomized controlled trial (RCT) with a 4-month follow-up to compare the effectiveness of our WMM-based stigma intervention to reduce viral load (VL) at 4-month follow-up (primary outcome) and improve the secondary outcomes of antiretroviral treatment (ART) and psychiatric treatment adherence, MH outcomes (e.g., depression), and social outcomes (e.g., social integration).

In Botswana, families are usually contacted and engaged in psychiatric treatment planning during inpatient stay or on admission. The involvement of family continues during outpatient follow-ups since most patients are accompanied by some relative or caregiver on such visits. Because family acceptance can bolster achieving the capabilities of 'good womanhood' (i.e., by being a family caregiver), family members will receive a parallel, group stigma intervention, which could further facilitate treatment adherence of the recently discharged family member. Therefore, the investigators will conduct a parallel two-arm intervention among women's family members to test its effectiveness in reducing family-level stigma and to assess family-level stigma as a mechanism of change for primary and secondary outcomes among women with SMI and HIV (e.g., VL, ART and psychiatric treatment adherence, MH outcomes and Social outcomes).

Participants in Research Aim 2 will be 75% female identified (100% of inpatient participants will be female-identified, and the investigators are accounting for a 50-50 gender split among recruited family members). Estimated distribution is 270 women, 90 men.

• Recruit 180 women to allow for 8% attrition post-intervention, with an added 8% during 4-month follow-up (below), to yield a final sample of N=151 expected to complete WMM or control (n=75 in each of 2 arms).
• The investigators expect to recruit ~180 family members to allow for 16% attrition overall, to yield a final sample of N=151 expected to complete the stigma intervention or control (n=75 in each of the 2 arms, under assumption that attrition on average occurs at the same rate in each arm).

RESEARCH AIM 3.

The investigators further propose to pilot and evaluate policymaker workshops whereby peer women with SMI and HIV share RCT findings via lived experience to policymakers to initiate structural-level change.

The investigators anticipate that the multisectoral stakeholder committee members (n=15) and policymakers (n=50) in Research Aim 3 will have ~50-50 gender split - 32 women, 33 men.

• The investigators plan to convene a Multisectoral Stakeholder Committee facilitate development of the policymaker workshops. Our MSC will include policymakers across multiple sectors: Ministry of Health (MoH), District Health Management Team (DHMT), Policy, Academic leaders
• The investigators additionally plan to recruit 50 policy makers to participate in the policymaker workshops in conjunction with 2-3 peer co-leader women with SMI and HIV to reduce stigma among policymakers and lay a foundation for sustaining interventions to improve HIV and other health outcomes in this vulnerable group.

OVERVIEW.

UBotswana will recruit participants and conduct the intervention, assessments, and data management. Overseen by PI Yang, NYU will provide study oversight, expertise in WMM and stigma, and conduct data analyses; UPenn will provide expertise in integration of the intervention for SMI and HIV; Botswana-UPenn Partnership will provide expertise in integration of peers into stigma interventions and implementation of community based interventions in Botswana; UCSF and UC Riverside will offer expertise and supervision in stigma interventions.

(A) WOMEN WITH SMI AND HIV

At Sbrana Psychiatric Hospital, the investigators will recruit women with SMI and HIV who are receiving treatment at that facility. Women with SMI and HIV will be receiving psychiatric care and ART and must:

• Meet DSM-5 criteria for current psychotic disorder or mood disorders or other disorders causing functional impairment except substance use disorders and developmental disorders, per clinician interview based on the MINI
• Have confirmed HIV positive status
• Be 18-55 years of age
• Be female
• Have capacity to provide consent and written informed consent
• Speak English or Setswana
• Be a Botswana citizen

The investigators will also recruit 6 to 8 women with SMI and HIV as peer co-leaders to facilitate the intervention. For women who are peer co-leaders, inclusion criteria include #1 to #7 above in addition to:

• Remaining adherent to psychiatric medications
• Being symptomatically stable for >2 years
• Maintaining consistent ART adherence.

(B) FAMILY MEMBERS OF WOMEN WITH SMI AND HIV.

In Botswana, families are usually contacted and engaged in psychiatric treatment planning during inpatient stay or on admission. The involvement of family continues during outpatient follow-ups since most patients are accompanied by some relative or caregiver on such visits. Eligible participants include:

• Identified by participant and/or clinician as the relative 'most involved in the client's care'.
• Be 18-65 years of age
• English or Setswana speaking
• Botswana citizen.

(C) POLICY MAKERS AND OTHER STAKEHOLDERS.

Policy makers will be

• Be 18-55 years of age
• Include: (a) bureaucratic officials of Botswana, public sector ministries (government) at the national level holding appointment to senior offices that develop, interpret and/or implement national mental health and HIV programs (prevention and treatment) or related clinical services; (b) senior bureaucratic officials of the National AIDS and Health Promotion Agency (NAHPA); and (c) senior members of civil society organizations (CSOs), nongovernment organizations (NGOs) or other entities that support the national Botswana government to implement services to People Living With HIV (PLWH) and mental health patients.
