Learning Objective 1: The learner will be able to identify values reflected in the Code of Ethics for Nurses with Interpretive statements.

Learning Objective 2: The learner will be able to utilize the NPVS-R to measure professional nursing values in students and/or practicing nurses.

Purpose: The purpose of this study was to examine the psychometric properties of the Revised Nurses Professional Values Scale (NPVS-R) in a random sample of baccalaureate and masters' students, and practicing nurses.  The NPVS-R is an instrument derived from the Code of Ethics for Nurses designed to measure nurses professional values.

Methods: The NPVS-R, a 26 item Likert-scale format instrument was tested on 782 subjects.  Responses to the NPVS-R were subjected to exploratory and confirmatory factor analysis. 

Results: Principal component analysis varimax rotation and Kaiser normalization resulted in a five factor solution explaining 56.7% of the common variance.  Findings supported internal consistency reliability with alpha coefficients from .70 to .85; total scale alpha coefficient of .92.  Construct validity was supported with an overall factor loading range of .46 to .79 across the five factors labeled Caring, Activism, Trust, Professionalism, and Justice.

Conclusion: The NPVS-R is a useful instrument for measuring professional nurses values and enhancing professional socialization.
