Abstract:
PURPOSE: This study was done to evaluate validity and reliability of the Korean version of the expanded nursing stress scale (ENSS). METHODS: Forward-backward translation of ENSS from English to Korean was conducted. The translated instrument was pilot-tested and administrated to 285 nurses who worked in five general hospitals in Korea. Internal consistency reliability was assessed using Cronbach's alpha and composite reliability. Validity was evaluated through construct validity with confirmatory factor analysis, convergent and discriminant validity. RESULTS: The Korean version of ENSS showed a reliable internal consistency with Cronbach's alpha .95 and composite reliability .99. Model fit indexes for 46 items were validated by confirmatory factor analysis(goodness of fit index .82, Tucker-Lewis index .92, root mean square error of approximation .04), indicating suitable construct validity. Factor loading of the 48 items (.47~.88) and average variance extracted out of nine factors (.52~.71.) indicated satisfactory convergent validity. Some values of square of the correlation coefficient between factors (.12~.89) were higher than average variance extracted values of each factor (.52~.71) so that it partly satisfied discriminant validity. CONCLUSION: Findings show that the Korean version ENSS has good reliability and suitable validity; therefore, can be used to assess and identify Korean nurses' job stress.
