Since 2016, Promotion of Human Rights of Persons with Disabilities in Bangladesh (PHRPB) has been working to include people with psychosocial disabilities in their community-based inclusive development work, and to increase access to formal mental health care. Field visits were carried out to PHRPBD catchment areas in Dhaka and Chittagong for a case study on the integration of mental health into community-based rehabilitation (CBR). This paper synthesizes the results of twenty-five semi-structured interviews carried out as part of the case study. Participants included people with psychosocial disabilities, intellectual disabilities, epilepsy or other cognitive impairments and their carers as needed. Interviews were audio-recorded, transcribed and translated from Bangla to English, then hand-coded for content analysis. Results were organized into five overarching categories: (1) explanatory models, (2) help-seeking behaviors, (3) impact of services, (4) challenges and barriers to improving mental health, (5) recommendations of users and carers. Respondents either had no explanation for why service users had become unwell or attributed it to physically and/or emotionally traumatic events or supernatural causes. Before attending PHRPBD's mental health services, most had visited formal or informal health care providers, often with disappointing results. Despite positive feedback on PHRPBD's services, participants identified ongoing challenges. Stigma, discrimination and human rights abuses persist and are compounded by issues of gender inequality. Participants also identified barriers and made recommendations specific to the program itself, mainly regarding accessibility (e.g., cost, distance, frequency). This study adds to the limited body of qualitative research on mental health in Bangladesh, reinforcing previous findings on explanatory models and health-seeking behaviors while providing new insights into the impact of a CBR program in this context. Feedback of service users and carers suggests that CBR may indeed be a useful approach to increase access to services in Bangladesh for people with psychosocial or intellectual disabilities, epilepsy or other cognitive impairments. However, this program is not without its limitations, some of which are the product of broader issues within the mental health system and others of the social and cultural context. More research is needed to formally evaluate this and other CBR programs in the Global South.
