Background & Aim: Increasing understanding of death anxiety among different cultures and patient populations is critical to provide quality patient care. Researchers who investigate death anxiety, are looking for a reliable and valid instrument compatible with culture in order to achieve this goal. The aim of the study was to evaluate the psychometric properties of the Templer’s Death Anxiety Scale-Extended (TDAS-E) among a sample of chemical veterans of Iran–Iraq warfare.

Methods & Materials: In this methodological study, 300 veterans completed the Persian version of the 51-item TDAS-E in 2015. The face, content and construct validity (convergent and discriminant validity) of the TDAS-E were assessed. Also, its reliability was measured using Cronbach’s alpha coefficient, construct reliability and intra correlation coefficient.

Results: Results of exploratory and confirmatory factor analyses extracted four stable distinct factors including fear of the hereafter, fear of facing death, fear of the shortness of life, fear of dying following an incident and mishap. The fitness of the four-factor model of the Templer’s death anxiety construct was approved based on standard indices (c2/df=2.832, GFI=.915, AGFI=.873, PCFI=.657, PNFI=.612, RMSEA=.078). Discriminant and convergent validity of all factors were acceptable. Also, scale reliability was confirmed using Cronbach’s alpha coefficient (0.88), construct reliability (higher than 0.70) and intra correlation coefficient (0.87).

Conclusion: The results of the current study revealed that the four-factor construct of TDAS-E had suitable validity and reliability among Iranian chemical warfare veterans. Given the proper psychometric properties, this scale can be used in future research to evaluate death anxiety in this population.
