Validity and Reliability Study of the Turkish Adaptation of the Disaster Response Self- Efficacy Scale (DRSES).

Objective: This study aimed to assess the validity and reliability of the Turkish version of the 'Disaster Response Self-Efficacy Scale (DRSES).'

Method: This is a methodological study to validate the DRSES. Third and fourth grade nursing students participated in the study (n = 340). Construct validity was evaluated by exploratory and confirmatory factor analysis. Reliability was assessed by internal consistency and test-retest reliability. Data were analyzed in SPSS 20.0 (IBM Corp., Armonk, NY, USA) and IBM SPSS AMOS 21.0. (IBM Corp., Armonk, NY, USA).

Results: The content validity was 0.96, Cronbach's alpha coefficient was 0.94, and the intraclass correlation coefficient for test-retest reliability was 0.95. The exploratory factor analysis revealed that 3 factors accounted for 59.4% of the explained variance. The factor loads ranged between 0.50 - 0.81. The construct validity was good (χ2/df = 2.54; RMSEA = 0.067; CFI = 0.93; NFI = 0.95; GFI = 0.93; TLI = 0.94; IFI = 0.92; < 0.001).

Conclusions: The results of this study show that the Disaster Response Self-Efficacy Scale is a valid and reliable tool that could be used to determine the nursing students' disaster response self-efficacy.
