This thesis is presented in three parts. Part One is a literature review of the key issues faced by women with gynaecological cancer, the need for psychosocial interventions, and the effectiveness of psychosocial interventions in meeting this need. Part Two presents the empirical paper. This paper explores how a new peer support service for women with gynaecological cancer was experienced by both the peer helpers and the women they were supporting. In Part Three, the issues and challenges raised during the completion of the empirical study are discussed.
