Globally, Deaf individuals experience disproportionately high rates of mental health conditions, yet their needs remain under-researched, particularly in low-resource settings. In Bangladesh, where ~10% of the population has disabling hearing loss, access to mental health services is extremely limited. Only one prior study has qualitatively explored Deaf adults’ mental health needs and experiences in Bangladesh, through participatory co-design workshops focused on communication and a Bangla Mental Health Sign Language Bank. Building on this, the current study used in-depth, one-to-one qualitative interviews to offer an individualised account of Deaf adults’ lived experience in the Bangladeshi context. Seven Deaf participants took part in semi-structured interviews in Bangla Sign Language (BdSL), facilitated by professional interpreters online, transcribed and coded in Bangla to preserve linguistic and cultural nuance. Thematic analysis revealed four interrelated themes: communication barriers and structural inaccessibility; emotional isolation and family neglect; mental health distress and suicidality; and resilience and peer support. These exploratory findings, while from a small sample, highlight the need for interpreter access in healthcare, greater mental health awareness within Deaf communities, and accessible service pathways. Larger-scale, more diverse qualitative and mixed-methods studies across Bangladesh are needed to build a stronger evidence base to inform policy and service development.
