Abstract

Purpose
The purpose of this study was to develop a scale to measure professionalism of clinical nurses and evaluate the reliability and validity of the scale.
Methods
DeVellis’s scale-development eight steps were applied. The initial items were developed through a literature review and discussion with investigators, and the content validity was verified by seven experts. The data were collected from 250 hospital nurses for exploratory factor analysis and 217 hospital nurses for confirmatory factor analysis. Exploratory and confirmatory factor analyses were utilized to assess the construct validity. Cronbach’s ⍺ was used to test the internal consistency reliability.
Results
The results of the exploratory and confirmatory factor analyses showed that the scale comprised four factors: professional skill(eight items), sense of ethics (five items), knowledge-seeking activities (four items), and autonomy(three items). The four-factor structure was validated (x² =600.85 p<.001, GFI=.88, CFI=.84, RMSEA=.07), and Cronbach’s ⍺ for the total scale was .84.
Conclusion
The study results showed satisfactory reliability and validity of the professionalism measurement scale for clinical nurses. This scale has potential as an appropriate instrument for measuring clinical nurse professionalism.
