Chinese version of the stressor scale for emergency nurse: A methodological study design

The aim of this study was to modify and test the psychometric properties of the Chinese version of the stressor scale for emergency nurses.

The methodological design was carried out in two phases: (a) form the Chinese version by Delphi method and (b) test the psychometric properties by cross-sectional survey.

The translated scale was administered to 420 nurses in Qingdao. Validity was assessed in terms of content validity, calibration correlation validity and construct validity using exploratory factor analysis and confirmatory factor analysis. Internal consistency was estimated using Cronbach α coefficients.

The Chinese version of the SSEN retains 27 items, four common factors were extracted by exploratory factor analysis, and the factor cumulative variance contribution rate was 78.463%. The fitting indexes of the four-factor model of CFA were all in the acceptable range[χ²  = 711.30, df = 312, p < 0.001, χ² /df = 2.280, CFI = 0.933, TLI = 0.924, IFI = 0.933, RMSEA = 0.079 (90% confidence interval = 0.071-0.086)].The item-level content validity index of the Chinese SSEN is 0.89 ~ 1.00; the scale-level content validity index is 0.98; the Cronbach α coefficient of the total table is 0.971 and the split-half reliability is 0.877.

The C-SSEN can be used to help nursing managers accurately formulate management measures to improve the stress coping ability of nurses in the ED, stabilize the nursing team and ensure nursing safety.
