The investigators will conduct a randomized controlled trial of Group Care in the GHESKIO Community Center versus Individual Care in the GHESKIO Adolescent Clinic for 160 HIV-infected adolescent girls age 16-23 years in Haiti (80 per arm). Adolescents randomized to Group Care will receive HIV services including integrated clinical and social support care in groups of 5-10. Adolescents randomized to Individual Care will continue to receive individual care at the GHESKIO Adolescent Clinic, which is the current standard of care (described below). If a subject declines to participate in the study they will continue to receive standard HIV care. Participants will be randomized to either Group Care or Individual Care in a 1:1 ratio using a computer generated random assignment.

Individual Care (standard of care): Adolescents randomized to Individual Care will receive care in the GHESKIO Adolescent Clinic which cares for both males and females age 13-23 years. The Adolescent Clinic waiting room has a television showing educational videos. After seeing a triage peer counselor and having their vital signs taken, participants see a nurse practitioner (NP) one-on-one in a private room for a 10-15 minute clinic visit. The NP may also provide family support counseling including family visits per clinical judgment. Each NP sees approximately 20 HIV-infected adolescents per day. The adolescent then returns to the HIV positive peer counselor, who provides one-on-one counseling for 30 minutes on topics chosen by the adolescent and the counselor. Each counselor sees \~10 adolescents per day.

Group Care (intervention): Adolescent girls randomized to Group Care will join a group within one week of study enrollment and receive care in the GHESKIO Community Center. The investigators estimate that it will take 4-6 weeks to constitute a full group of 5-10. During this enrollment phase, groups will meet weekly, adding new participants each week. The participants will then meet monthly with an NP and a HIV positive peer counselor. Each monthly group session will last \~2 hours. This is comparable to the time it takes for a patient to pass through the Adolescent HIV Clinic. It will start with a 30 minute unstructured discussion. This time is intentionally unstructured and responds to our previous research finding that adolescents want to talk about topics of their choosing with their peers. This will be followed by a 45 minute group counseling session following a structured curriculum, addressing topics such as social isolation, stigma, family support, sexual risk behavior, life goals, medication adherence, job skills, and transitions. This is followed by a 30 minute social activity led by two rotating group leaders who are elected by their peers. Social activities include crafts, playing cards, and charades. Participants will be seen one by one by the NP for \~10-15 minutes in a screened in clinical area during the unstructured discussion and the social activity. All HIV clinical services, including provision of antiretroviral therapy (ART) medications, CD4 T cell monitoring, screening for symptoms and OI, medication adherence monitoring, family planning, and general primary care will be provided by the NP. Girls who become eligible for ART will be provided with individual counseling and promptly initiated on ART by the NP. The primary hypothesis is that Group Care will improve retention at 12 months compared with standard Individual Care. The study has \> 90% power to detect a difference in retention from 60% to 85%. Participants in both study arms will complete a questionnaire with a research nurse at enrollment, 6, and 12 months collecting data on HIV knowledge, HIV-related stigma, HIV disclosure, social and family support, depression and alcohol use, problem solving skills, and food insecurity.
