Turkish version of the revised nursing professional values scale: Validity and reliability assessment

Abstract

Aim: The purpose of this study was to assess the reliability and validity of a Turkish version of the Revised Nursing Professional Values Scale (NPVS-R). Methods: The sample of this methodological study consisted of 385 participants, including senior undergraduate nursing students (n=328) and clinical nurses (n=57). Data was collected using the NPVS-R. For NPVS validity, content validity and construct validity were analyzed. The content validity index (CVI) was used to determine item validity. Results: Item CVI ranged from 0.78 to 1.0, and total CVI was 0.93. Construct validity was examined using factor analysis and the five factors were identified as original NPVS-R. Chronbach's alpha was used to assess the internal consistency reliability. The 26-item NPVS had a standardized alpha coefficient of 0.92. Test-retest reliability scale was r=0.76 (P<0.001). Conclusion: Our analyses showed that the Turkish version of NPVS-R has high validity and reliability. © 2012 Japan Academy of Nursing Science.
