The validation of the Multidimensional Orientation Toward Dying and Death Inventory in an Iranian People

Introduction and Objective: The Multidimensional Orientation Toward Dying and Death Inventory (MODDI-F) is a ۴۷-item self-report scale. This study aimed to assess the psychometric properties of the MODDI-F in a sample of Muslims.Research Methodology: In this study, which was a cross-sectional design, ۴۶۵ individuals (۲۲۰ men and ۲۴۵ women) were selected by random sampling and completed the Death Anxiety Scale (DAS), the Death Obsession Scale (DOS), the Death Depression Scale (DDS), and the MODDI-F. Data were analyzed using principal component analysis and multiple analyses of variance (MANOVA).Findings: The factor analysis results using principal component analysis (PCA) showed that the MODDI-F was a multidimensional scale and four factors including fear of oneself death, fear of other’s death, death loneliness, and death acceptance explained the most variances respectively. Females had higher scores on the MODDI-F than males. In order to examine concurrent validity of the MODDI-F, the relations of the MODDI-F to the DAS, the DOS, and the DDS were investigated. The results showed that the MODDI-F had an appropriate concurrent validity. In addition, three types of reliability (test-retest, split-half, and internal consistency) were reported.Conclusion: Considering desirable psychometric properties of the MODDI-F in the present study, this scale can be used in research on death among Iranian people.
