One of the core features of mental health is psychological well-being, which includes enjoyment, pleasure, happiness, fulfillment, and resilience. Assessing psychological well-being might be a useful indicator in determining the effectiveness of a research study or the appropriateness of a clinical intervention. The gender and sexually diverse people (GSDP), including men who have sex with men (MSM), male sex workers (MSW), and transgender women (hijra), are subject to widespread stigma and discrimination in Bangladesh that imposes a great mental health burden by compromising their mental health and well-being. The Bangla WHO-5 Well-being Index may be considered a promising and useful instrument for assessing the well-being of GSDP. However, the psychometric properties of the Bangla WHO-5 Well-being Index on GSDP have never been explored in Bangladesh.
