Abstract: (2714 Views)
Objective: The Death Obsession Scale which was developed by Abdel-Khalek in Egypt, is designed to measure preoccupation, impulses and persistent ideas regarding death. The aim of this study was to investigate the psychometric properties of this scale in Iran.
Method: The current descriptive cross-sectional research was carried out in an ex-post facto research context. The Death Obsession Scale was administered to 342 individuals (126 males and 216 females), who were selected using random sampling from different schools of Allameh Tabatabie University.
Results: Factor analysis via analysis of the essential elements indicated three factors, namely, ``death rumination``, ``death dominance``, and ``death idea repetition``. No significant difference was observed between males and females regarding death obsession scale and its factors. To test concurrent validity, death anxiety scale was administered simultaneously, which indicated an appropriate concurrent validity. In addition, the presence of three types of reliability was reported (test-retest, half splitting, and internal consistency).
Conclusion: The results of factor analysis were in line with other research in the literature and reliability and validity coefficients were similar to previous findings. Regarding the features of appropriate psychometrics, the instruments in the present study can be used in research related to death. However, since the study was only limited to university students, there should be a limitation to generalizing the results of the present research to other social groups.
