The Reliability and Validity Study of Turkish Version of the Death Depression Scale-Revised Among Nurses

Abstract

The study aimed to establish the reliability and validity of the Turkish version of the Death Depression Scale-Revised (DDS-R) with a sample of 284 nurses. Cronbach’s coefficient for the whole scale was .909 and the sub-dimension values were calculated as .934, .798, .715, and .537. The test-retest reliability coefficient was found to be .880. The content validity index (CVI) of the scale was calculated as .86. The results of the exploratory factor analysis showed that 62.254% variance was explained in 4 sub-dimensions of the scale (existential vacuum, death emptiness, other death, death sadness). Confirmatory factor analysis revealed that a four-dimensional structure yielded a good fit (X2/df = 3.124, RMSEA = .087). TDDS-R was found to be a valid and reliable measurement tool in determining the death depression levels of nurses.
