IntroductionThere is an increasing concern about the mental health and mental well-being of university students in the UK. Black university students who report a mental health condition are less likely to complete their course, achieve a first-class or upper second-class degree and progress to further education. This study will document black university students’ accounts of their mental health experiences and perceptions of key turning points of biographical changes to their mental health as they move through the university life cycle.Methods and analysisThis is a qualitative study. Data will be collected through a biographical narrative interpretive method. Interviews will enable the researcher to study systematically how participants make sense of themselves and account for the complexities of their life experiences, from their own perspectives and language. An interpretative phenomenological approach will be used to offer insights into what black students studying at UK universities report affects their mental health and well-being. Data collection for this study commenced in October 2020. Data collection and analyses will be completed by January 2022.Ethics and disseminationFull ethical approval for the current study was obtained from King’s College London Psychiatry, Nursing and Midwifery Research Ethics Subcommittee (Rec Ref: 20489, Project Ref: HR-19/20-20489, 2 October 2020). From the study findings, we aim to contribute to the evidence base, make recommendations for interventions and encourage further study into black student mental health.
