This study aimed to adapt the Nurses Professional Values Scale-3 (NPVS-3) for Korean nursing students and assess its reliability and validity.
Methods
The NPVS-3 was translated into Korean using forward and back translation with expert review. Data from 206 nursing students at four universities were analyzed to assess content, construct, discriminant, and criterion validity, as well as internal consistency.
Results
The Korean version (NPVS-3K) consisted of 21 items in three subscales: caring (eight items), activism (eight items), and professionalism (five items), explaining 60.9% of the total variance. For convergent validity, standardized coefficients for the items ranged from .56 to .81, construct reliability ranged from .89 to .95, and the average variance extracted ranged from .61 to .72. The model was validated by confirmatory factor analysis (χ2=526.00 [p<.001], χ2/degrees of freedom=2.83, standardized root mean residual=.03, goodness of fit index=.81, comparative fit index=.87, Turker Lewis index=.85). Discriminant validity was confirmed using a multi-trait and multi-item matrix. Criterion validity showed positive correlations between the three NPVS-3K factors and professional identity (factor 1: r=.40, p<.001; factor 2: r=.55, p<.001; factor 3: r=.43, p<.001). Internal consistency, as measured by Cronbach’s α, was .94 overall, with subscale values of .90 for caring, .92 for activism, and .78 for professionalism.
Conclusion
The NPVS-3K demonstrated satisfactory validity and reliability, establishing it as a valuable tool for assessing the professional values of Korean nursing students. Additionally, it can aid in developing educational strategies to strengthen these values, although further research is required to confirm its broader applicability.
