Models of Integration for Mental Health and HIV/AIDS Among Adolescents and Young People in Low- and Middle-Income Countries: A Scoping Review.

Adolescents and young people (AYP) experience a disproportionate burden of both mental health conditions and HIV, particularly in low- and middle-income countries (LMICs)-nations classified by the World Bank as having lower or middle economies. Mental health problems such as depression, anxiety, and substance use increase HIV (Human Immunodeficiency Virus that attacks the human immune system and leads to various illnesses when untreated) risk, and negatively affect treatment adherence and outcomes. However, mental health remains insufficiently integrated into HIV research and programming. Evidence on how mental health services are operationally integrated into HIV prevention and treatment for this population is limited and fragmented. This scoping review mapped existing evidence on the integration of mental health services into HIV treatment programs for AYP in LMICs, guided by PRISMA-ScR (a guideline used for reporting scoping reviews in research) and the Person-Concept-Context framework, a framework used to define specific research question in research. In this case, the population was adolescents and young people (10-24 years) receiving HIV prevention or treatment services, the concept referring to the integration of mental health interventions such as screening, assessment and counseling within HIV services, and the context focused on low- and middle-income countries (LMICs). PubMed, MEDLINE, Scopus and PsycINFO databases were searched for studies published between 2014 and 2024. Eligible studies reported mental health screening, assessment, treatment, or referral within HIV services for AYP in LMICs. Two reviewers independently screened studies, assessed full texts, and extracted data. Of 634 records identified, ten (10) studies met the inclusion criteria. All were conducted in Sub-Saharan Africa and primarily used qualitative or pilot designs. Four integration approaches were identified: routine mental health screening within HIV services, task-shifting to trained lay providers, peer-led and community-based psychosocial support, and culturally adapted, youth-centered psychological interventions. Common barriers included stigma, low mental health literacy, limited training and supervision, staffing constraints, and weak referral systems. Existing evidence is limited, remains exploratory, preliminary, and largely focused on feasibility and implementation experiences, suggesting that integrating mental health services within adolescent HIV care in LMICs may be feasible and acceptable when approaches are contextually adapted and participatory.
