Understanding excessive rates of psychosis in ethnic minority populations, through the life-narratives and perspectives of Black-Caribbean patients

Background Individuals from specific ethnic populations are at increased risk of developing psychosis. Although socio-environmental adversity is cited as the main cause, current theoretical perspectives remain limited. This study adds to the debate about psychosis excess, by examining the qualitative accounts and perspectives of racialised patients. Method Drawing on a phenomenological and life narratives approach, 13 semi-structured interviews were conducted with Black/Black-British Caribbean patients recovering from their first episode of psychosis. Interviews elicited key aspects of the patients’ lives and obtained their reflections on the perceived cause of their first episode. Interviews were analysed thematically. Results Seven themes captured the life events of the patients. These were: Interpersonal Relationships and Social Interactions; Employment; Hobbies and Personal Interests; Educational Attainment; Cannabis use; Migrating to England and Religiousness. Being mistreated by others, cannabis use, and the cumulative effect of all of life’s negative circumstances were cited as causes of their first episode. Discussion Our findings are discussed in the context of interpersonal trauma, cultural differences in the response to mental distress and social group theory. We also consider the role of cannabis use as a social process and the cumulative effect of negative life events. The limitations of this work are discussed along with recommendations for further research.
