Validity and Reliability of the Korean Version of the Post-Code Stress Scale

Jin Hee Park, Eun Nam Lee, Dong Hee Cha


Purpose: This study aimed to evaluate the validity and reliability of the Korean version of nurses’ Post-Code Stress Scale (PCSS).

Methods: The process of translation followed Brislin’s back-translation model. The internal consistency reliability and construct validity of the translated scale were evaluated using confirmatory factor analyses. This scale was distributed to 168 nurses who had experience of performing cardiopulmonary resuscitation on duty and who had worked in an intensive care unit, emergency department, or medical-surgical ward in which cardiopulmonary resuscitation was frequently performed.

Results: For internal consistency, Cronbach's α ranged from 0.76 to 0.87 for the 4 subscales of the Korean PCSS. Meanwhile, the factor loadings of the 13 items across the 4 subscales ranged from 0.61 to 0.89. Further, the 4-subscale model was validated using confirmatory factor analysis (χ2/df = 2.3, p < 0.001, GFI = 0.9, RMSEA = 0.08, NFI = 0.9, TLI = 0.91, CFI = 0.94).

Conclusions: This study shows that the Korean PCSS is a valid and reliable instrument for measuring Korean nurses’ stress after experiencing situations involving cardiopulmonary resuscitation.
