Measures of spiritual issues for palliative care patients: a literature review.

Members of the Quality of Life Group (QLG) of the European Organisation for Research and Treatment of Cancer (EORTC) are developing a stand-alone functional measure of spiritual well being for palliative care patients, which will have both a clinical and a measurement application. This article discusses data from a literature review, conducted at two time points as part of the development process of this instrument. The review identified 29 existing measures of issues relating to patients' spirituality or spiritual well being. Twenty two are stand-alone measures of which 15 can be categorised as substantive (investigating the substance of respondents' beliefs) and seven as functional (exploring the function those beliefs serve). However, perhaps owing to the lack of consensus concerning spirituality or spiritual well being, the functional measures all have different (although sometimes overlapping) dimensions. In addition, they were all developed in a single cultural context (the United States), often with predominantly Christian participants, and most were not developed with palliative care patients. None is, therefore, entirely suitable for use with palliative care patients in the United Kingdom or continental Europe.
