This article describes a study in which a systematic classification of cancer patients was produced on the basis of their needs. A series of 380 cancer patients from four hospitals in the North West of England responded to a self-completion questionnaire that included a 48-item inventory of psychosocial needs covering seven needs domains (information, health professionals, emotional and spiritual, identity, practical, support, and child care). Latent class analysis was used to identify differing patterns of psychosocial need. Four patterns of need were identified.
