DOI : 10.31067/0.2020.301 Objective: In Turkey, unfortunately, there is no measuring tool to determine nurses" disaster response self-efficacy and thus appropriate tools should be either developed or adapted. This methodological study was designed to determine the validity and reliability of the Turkish version of the "Disaster Response Self-Efficacy Scale (DRSES)".

Materials and Methods: The data were collected through face-to-face interviews. The study sample comprised 271 3rd and 4th year students who attended a Nursing Faculty and accepted to participate in the study. In adapting the scale into Turkish, the translation and back-translation method was used. The Content Validity Index was used to test the content validity, the Exploratory and Confirmatory Factor Analysis was used for determining the construct validity, and Cronbach"s alpha value and item total correlation were used to test the reliability.

Results: The content validity index for the Disaster Response Self-Efficacy Scale was 0.99. The Cronbach alpha coefficient was 0.96. For on-site rescue competency, disaster psychological nursing competency, disaster role quality and adaptation competency subscales, it was 0.93. The item-total correlation was positive and high. The factor analysis revealed that the scale had a three-factor structure and that similar items were grouped under the same factors. Confirmatory factor analysis revealed the following values: RMSEA: 0.077, GFI: 0.87, CFI: 0.98, IFI: 0.98, RFI: 0.97, NFI (TLI): 0.97, and x2/df: 2.604.

Conclusion: It was concluded that the Turkish version of the Disaster Response Self-Efficacy Scale was a reliable and valid measurement tool that could be used to determine the nursing students" disaster response self-efficacy. Keywords : Disaster, nursing, self efficacy,validity, reliability
