Data were collected from 475 clinical nurses working in hospitals using a questionnaire that included 40 items (consisting of 5 subscales) of the Korean version of the CPQ and 2 items of nursing confidence. The collected data were analyzed using SPSS 25.0. The characteristics of the nurses were calculated as a percentage and mean with standard deviations. Pearson's correlation was used to analyze the correlation between the sub-domains of the Korean CPQ tool and the characteristics of the nurse.
