Increasing Social Support to Improve HIV Care Engagement and Adherence in St. Petersburg, Russia

Increasing Social Support to Improve HIV Care Engagement and Adherence

Prior research has documented serious health, mental health, and social-behavioral issues among people living with HIV (PLH) in St. Petersburg. The investigators have established that PLH are clustered in friendship groups with other HIV+ persons and that an intervention delivered to groups composed of HIV+ men who have sex with men (MSM) who were friends in real life reduced mental health distress more than individual counseling. Specific aims of the collaborative mixed-methods, qualitative/ quantitative research are to: (1) identify facilitators and barriers of medical care attendance and ART adherence among PLH in St. Petersburg; (2) integrate these data into an intervention designed to increase HIV care attendance, retention, and adherence; (3) carry out a test-of-concept pilot study that recruits groups of PLH friends and delivers an intervention to intact PLH friendship groups to encourage mutual social support for attending medical appointments and adhering to HIV care; and (4) evaluate the effects of the intervention on both behavioral and biological measures, including viral load. These specific aims will be achieved by research carried out in two phases:

In Phase I, we will conduct in-depth interviews with 60 PLH and key informants in St. Petersburg purposively selected to include HIV+ persons in and not in medical care, adherent or not adherent to ART, and including men and women representing diverse exposure risks. In-depth interviews will be analyzed to identify factors associated with attending or not attending care and adhering or not adhering to ART, as well as identifying how HIV+ friends can support one another in HIV care entry, retention, and adherence.

In Phase II, the investigators will undertake a randomized intervention pilot study in which 20 groups of PLH friends are recruited by enrolling a PLH seed who is not reliably in care or is ART nonadherent and then recruiting all friends known by the seed to also be HIV+. A 7-session group intervention will be undertaken with all members of the friendship groups in the experimental condition to increase care and adherence-related social support, problem-solving, and mutual assistance for care. Baseline to 6-month followup data will determine whether the intervention produces greater improvement than found in the comparison group in care attendance and treatment adherence, improved mental health, lower substance use, and lower HIV viral load.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Social Support; Participants will be trained to give one another ongoing, theory-based but personally-tailored advice, recommendations, and support to encourage entry to HIV medical care, remaining in care, and adhering to medication regimens when they are prescribed. The intervention's intent is to increase mutual support, positive attitudes, intentions, plans, and collective self-efficacy for care engagement.	Behavioral: Social Support; Other Names: Social Network Training
No Intervention: No Intervention; Participants in this arm will not receive an intervention.
