reliability and validity of the persian version of templer death anxiety scale-extended in veterans of iran–iraq warfare

objective: the purpose of this study was to determine the validity and reliability of the persian version of templer death anxiety scale-extended (das-e) in veterans of iran–iraq warfare. methods: in this cross-sectional study, 211 male veterans of iran–iraq warfare completed the 51 item dase. principal components analysis with varimax rotation was used to assess domain structure of the das-e. internal consistency reliability was assessed with cronbach’s alpha. test–retest reliability was assessed with intra-class correlation coefficients for absolute agreement for the individual items and domains. results: the construct validity of the scale was obtained using exploratory factor analysis that showed four factors with eigen values of greater than 1 (1, 11 items, α = 0.83 2, 7 items α = 0.87 3, 5 items, α = 0.73 and 4, 4 items, α = 0.75). test–retest and internal consistency (total alpha) was 0.91 and 0.89, respectively. conclusion: the das-e demonstrated suitable validity and reliability among the veterans under study. the factor analysis demonstrated that the das-e has a multi-dimensional structure. with consideration of the proper psychometric characteristics, this scale can be used to further research about death anxiety in this population.
