Evaluation of the validity and reliability of the Korean version of the Nursing Professional Values Scale-Revised

Background: The development of professional values is a significant factor in improving nursing practice. It is important to develop nursing curricula for establishing and investigating nursing students' professional values. Professional values of Korean nursing students may differ from those of nursing students in other countries, and research on the professional values of Koreans using a validated scale is needed. Objectives: The purpose of this study was to test the validity and reliability of the Korean version of the Nursing Professional Values Scale-Revised. Methods: Convenience samples of 1077 baccalaureate nursing students were recruited from four universities in Korea. Construct validity and internal consistency reliability using explanatory factor analysis were examined. Results: The validity was obtained using a principle component analysis of a five-factor structure (variance explained 58.90%). The five factors were labeled human dignity, professionalism, innovation, contribution, and advocacy. The Cronbach's alphas were .93 for the total scale and .89-.62 for the subscales. Conclusions: The overall Korean version of the Nursing Professional Values Scale-Revised was valid and reliable for measuring nursing professional values. Criterion-related validation of the Korean version of the Nursing Professional Values Scale-Revised and the development of items congruent with Korean culture are needed to support the validity and reliability of the Korean version of the Nursing Professional Values Scale-Revised.
