Patient and public involvement is imperative to ensure relevance of research. There is a growing literature on the theoretical underpinning on patient and public involvement including level and processes of involvement. The aim of this paper is to describe a person-centred and culturally sensitive approach to working with minority ethnic communities, involving carers, people living with dementia, members of the public and carer support workers, as used in the Caregiving HOPE study; and the influence of the approach on the study's research processes and outcomes. Patient and public involvement members were considered experts by experience and involved with study conception, design, conduct and dissemination. The perspective of the experts by experience is also presented in this article. The level and nature of involvement was influenced by each individual's needs and desires which changed over the course of the study. The approach had a significant impact on study outcomes as evidenced by successful recruitment and engagement at a national level, but was not without challenges with greater flexibility required and fuller consideration of financial and time costs required. Benefits of the approach included strong engagement, improved outcomes (successful recruitment of seldom heard groups) and meaningful relationships between researchers and experts by experience. A person-centred and culturally sensitive approach is required with patient and public involvement to ensure involvement is not detrimental to those involved, is meaningful and enjoyable and has a positive impact on the research.
