Depression poses a global challenge, imposing significant personal and societal burdens. In the United Kingdom, the rates of depression have increased, making it one of the most common mental health issues in the country and cited as a leading contributor to male suicide. Given that men are less likely to seek help for depression and more inclined to mask their expressions of it, it is crucial to understand men’s beliefs about depression to improve prevention and intervention strategies. However, while the United Kingdom is a diverse society with a predominantly Christian population, Muslim men, as a religious and ethnic minority group, are less likely than any other demographic to seek help for depression. Furthermore, the voices of Muslim men remain absent from academic literature, and their beliefs about the Western concept of depression are still unexplored, leaving them vulnerable to inequalities in accessing mental health services. Guided by the principles of liberation psychology, this study conducted two tasks as initial steps towards empowering Muslim men and developing religiously sensitive mental health care tailored for them. The first task involved recovering historical Islamic scholarship on concepts related to depression to shed light on Islam’s rich and holistic tradition of understanding and treating mental health difficulties related to depression. The second task, which comprises the bulk of the thesis, involved utilising participatory research, virtual focus groups, and photo-elicitation as a decolonial research approach to explore Muslim men’s beliefs about depression. Through thematic analysis, this task revealed Muslim men’s conceptualisations of depression, encompassing both religious and non-religious perspectives. It explored the role of Islam in managing experiences such as sadness and the influence of Islamic masculinity on their understanding of depression. Finally, it shed light on social and systemic barriers Muslim men face in accessing appropriate mental health care for this condition. The study’s findings are discussed in relation to the literature on psychology, religion, and psychotherapy.
