Dementia Care Mapping (DCM): initial validation of DCM 8 in UK field trials

Abstract

This paper describes DCM 8 and reports on the initial validation study of DCM 8. Between 2001-2003, a series of international expert working groups were established to examine various aspects of DCM with the intention of revising and refining it. During 2004-2005 the revised tool (DCM 8) was piloted in seven service settings in the UK and validated against DCM 7th edition. At a group score level, WIB scores and spread of Behavioural Category Codes were very similar, suggesting that group scores are comparable between DCM 7 and 8. Interviews with mappers and focus groups with staff teams suggested that DCM 8 was preferable to DCM 7th edition because of the clarification and simplification of codes; the addition of new codes relevant to person-centred care; and the replacement of Positive Events with a more structured recording of Personal Enhancers. DCM 8 appears comparable with DCM 7th edition in terms of data produced and is well received by mappers and dementia care staff.
