Adolescence, defined as the period between 10 and 19 years of age, is a developmental stage during which many psychosocial and mental health challenges emerge. There is a well-established link between mental health and HIV outcomes. Adolescents and young adults living with HIV typically have additional mental health needs linked to their experiences of living with and managing a chronic illness, along with prevailing stigma and discrimination. Mental health promotion and prevention is thus a critical priority for this group.
