dc.description.abstractThe aim of this study was to adapt the short form of Death Literacy Index (DLI-9) into Turkish and to examine its psychometric properties. This study has a methodological cross-sectional design. The study was conducted with a sample of 400 adults across T & uuml;rkiye during October-November. Content Validity Index, Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), Convergent and Discriminant Validity Analyses, test-retest reliability, Cronbach's alpha-coefficient, item-total-score correlation, 27% upper-lower-group item analysis and Hotelling-T2 test were used in data analysis. In the EFA analysis, the scale consisted of 2 factors. The original two-factor structure of the scale was confirmed by CFA. CFA model fit values were found as CMIN/DF = 2.078, RMSEA = 0.074, RMR = 0.077, SRMR = 0.0455, CFI = 0.960, NFI = 0.927, TLI = 0.945, GFI = 0.946, and AGFI = 0.906. The total Cronbach's alpha reliability coefficient of the DLI-9 was found to be 0.84. This study indicates that scale is a reliable tool for evaluating death literacy in the Turkish population.
