? DESCRIPTION (provided by applicant): As pediatric HIV infection has shifted from being a fatal disease to a chronic illness, a growing cohort of young people are moving through adolescence with all the challenges of the adult HIV-infected population but largely without comparable treatment outcomes or an evidence base to improve adherence to antiretroviral treatment (ART) and preventive behavior. Despite overall declines in HIV incidence and mortality since the ART scale-up, both have risen among youth. The goal of the proposed 3-year R34 developmental study is to respond to this need for tailored research, in particular among HIV+ older adolescents, and contribute to understanding the added value in resource-limited settings of including caregivers in an adherence and risk reduction program. Although caregiver involvement is a recognized correlate of outcomes in HIV+ youth, there are no rigorous studies of the role of caregivers in outcomes among HIV+ older adolescents. This project will integrate caregiver involvement and cognitive behavioral intervention (CBI) elements to improve ART adherence and HIV risk reduction for HIV+ older adolescents treated in resource-poor clinical settings. Our proposed study population will include caregivers and 15 to 19 year-old HIV+ youth who know their status and are receiving ART in Port-au-Prince, Haiti. Guided by the theoretical framework of the developmentally sensitive Information-Motivation-Behavioral Skills for Pediatric Adherence (IMB-PED), we will develop Growing Up (N'ap Grandi, in Haitian Creole) as a collaborative model of caregiver-adolescent engagement in the key informational, motivational, and behavioral skills antecedents of ART adherence and risk reduction. The proposed study partners with Haiti's largest youth health provider, FOSREF, and builds upon prior work with HIV+ youth and adults in Port-au-Prince. The study will utilize qualitative and quantitative methods to: identify barriers and facilitators to adherence and risk reduction (Aim 1); develop and pretest N'ap Grandi, including developmentally-appropriate manuals, training materials, procedures, and psychometric adequacy of measures (Aim 2); and assess feasibility and preliminary efficacy in a 3-arm randomized controlled trial (RCT), in which 120 youth will be assigned to three groups: the experimental caregiver-adolescent N'ap Grandi, an adolescent-only version (N'ap Grandi-A) and an adolescent-only health promotion group (HP-A), examining ART adherence and virologic response, HIV risk behaviors, positive communication and monitoring, stress and mood, and costs from the health center perspective (Aim 3). Isolation, inhibited communication, caregiver distress, adolescent ART non-adherence and HIV risk are very high in Haiti, which is a microcosm of the global pediatric HIV epidemic in low and middle income countries (LMICs) with generalized epidemics. After sub- Saharan Africa, the Caribbean is the most HIV-affected region in the world, with 50% of people with HIV infection living in Haiti. Our proposed study will be the first tailored intervention and RCT pilotd for HIV+ adolescents in Haiti, and will represent one of only a handful in LMICs globally.
