AbstractThe purpose of this study was to establish whether or not readiness for death, as an indicator of healthy dying, is a measurable concept. Review of relevant literature revealed consensus regarding the universality of a human need for healthy dying. A theory of healthy dying was derived from the Rogerian paradigm. The McCanse Readiness for Death Instrument (MRDI) was constructed, which included indicators of physiological, psychological, sociological, and spiritual aspects of "healthy" field pattern as death is developmentally approached. The MRDI was a 26-item structured interview questionnaire which generated interval-ratio data through a visual analog scale. A pretest was conducted with a sample of 9 volunteer patients drawn from a small suburban outpatient hospice. The MRDI was concurrently administered to dying individuals, their primary caregivers, and their primary hospice nurses. Correlations between dying individuals' scores and their primary caregivers' estimates of patient death readiness as well as between patients and their primary hospice nurses were very encouraging. Cronbach's coefficient alpha for internal consistency reliability was .59. Content validity was supported by consensus of an expert panel of practicing hospice nurses. Construct validity was demonstrated through legitimate placement of the concept, healthy death readiness, within the theoretical web which supported it. The MRDI was then administered to a sample of 31 terminally-ill individuals, their primary caregivers, and their primary hospice nurses drawn from larger, urban hospice populations in three geographic areas of the United States. The MRDI was also administered to a contrast group of 39 cardiac-impaired individuals who were not terminally-ill. Overall internal consistency of the MRDI was found to be quite favorable (alpha = .76). Debilitating illness and actual mortality in the study sample precluded and/or confounded estimates of test-retest reliability. Convergent validity of the MRDI was indicated by significant correlations between patients' scores and primary caregivers' estimates (r = .35, p < .05) and between patients' scores and primary hospice nurses' estimates (r = .53, p < .01). Discriminant validity of the MRDI was demonstrated by a significant mean difference between the group of terminally-ill patients and the group of non-terminal, cardiac-impaired patients (t = 1.76, p < .01).
