Lay summary
The term Rainbow+ (also known as LGBTTQIA+ or MVPFAFF+) refers to people with diverse sexualities (like being lesbian, gay, bisexual), diverse gender identities (e.g. transgender, non-binary), and those with variations in sex characteristics (intersex). Young people aged 16 to 24 who identify as Rainbow+ often face greater challenges to their mental health than their non-Rainbow+ peers, including a higher burden of depressive symptoms, self-harm, and suicidal ideation. Many also experience barriers when trying to access mental health services. This research will identify specific ways in which mental health services and policy can be better targeted to the needs of Rainbow+ youth. Increased access to and use of services by Rainbow+ communities may lead to improved health outcomes and reductions in direct healthcare costs.
