Validity and Reliability of the Turkish Version of the Death Literacy Index

Death literacy is defined as a set of knowledge and skills that make it possible to gain access to, understand, and act upon end-of-life and death care options. This study was conducted to test the validity and reliability of the 29-item original version of the Death Literacy Index (DLI) in Turkish society. The scale was applied on a sample of 436 Turkish adults determined using the snowball sampling method. Explanatory and confirmatory factor analyses were performed. The scale consisted of 6 subscales. The test-retest analysis of this study showed a strong and highly significant positive correlation between overall DLI (.98) and its subscales (.73–.98). The total Cronbach’s alpha reliability coefficient of DLI was found to be .90. It was observed that the Turkish version of DLI was a valid and reliable tool and suitable for use in Turkish society.
