This thesis examines the challenges of integrating LGBTQ+ inclusivity into HongKong’s mental health care system, focusing on barriers to effective psychiatric services forlesbian, gay, bisexual, transgender, and queer individuals. Guided by Queer Theory andIntersectionality, the study addresses two research questions: how the current system meetsLGBTQ+ needs and the primary challenges faced by providers in delivering inclusive care.Through semi-structured interviews with two service users and one psychiatric nurse, thematicanalysis identifies four barriers: lack of cultural competence training, heteronormative normsand cultural stigma, lack of policy implementation, and resource constraints. Policy analysis ofHong Kong’s key documents, including the Mental Health Review Report (2017) and HospitalAuthority Guidelines (2019), reveals absent provisions for LGBTQ+-specific stressors, suchas stigma and family rejection. International policy references from Taiwan, Singapore,Australia, the UK, and Canada contextualize these gaps, highlighting inclusive practices likemandated training. Findings indicate that Hong Kong’s system fails to provide affirming care,exacerbating mental health disparities, while providers face inadequate training, cultural biases,legal ambiguities, and resource shortages. The study contributes theoretically by applyingQueer Theory and Intersectionality to Hong Kong’s context, empirically by filling gaps in livedexperiences and provider perspectives, and practically by informing inclusive policy reforms.
