Measuring death anxiety: conceptual, psychometric, and factor-analytic aspects.
This study was undertaken to construct a brief, reliable, and valid questionnaire for measuring attitudes toward death and dying. In Stage 1, four groups of individuals ranging in age from 30 to 82 years completed the Death Anxiety Questionnaire (DAQ), a brief anxiety scale (MAS), and a depression scale (DP). During Stage 2, results on these scales were cross-validated on a new sample of subjects, and the Templer and Dickstein measures of death anxiety were also completed. Internal consistency of the DAQ as determined by coefficient alpha was .83 (n = 230) and test-retest reliability was .87 (n = 30). No significant sex or age differences were found for any of the groups tested. Results provided evidence for both construct and concurrent validity of the DAQ and for discriminant validity of the items. A principal-components factor analysis suggested four independent dimensions of death anxiety: Fear of the Unknown; Fear of Suffering; Fear of Loneliness; and Fear of Personal Extinction. Recommendations for future research include an investigation of the degree to which scores on these four dimensions might differentiate among different sex, age, personality, affective, and diagnostic groupings.
