Psychometric evaluation of the nurses professional values scale-3: Indonesian version

Abstract

The Nurses Professional Values Scale-3 (NPVS-3) is an important instrument for measuring the development and sustainability of professional values in nurses and nursing students. The translation, adaptation, and validation on this scale, including in Indonesia, is still very limited. The purpose of this study was to examine the Indonesian version of NPVS-3. This study used forward and backward translation methods and a cluster random sampling of 600 nurses participated. The 28-item scale of NPVS3-I was tested using EFA, applying the principal axis factoring extraction method and varimax with Kaiser normalization rotation method. The CFA used SEM with AMOS. Findings suggested sufficient content validity, construct validity, and reliability of the Indonesian version of NPVS-3. The I-CVI values ranged between 0.80 to 1.00 and the S-CVI was 0.99. Construct validity was supported with loading factors ranging from 0.49 to 0.84 for three factors (Caring, Activism, and Professionalism). The CFA goodness-of-fit indices were X2 (df ) = 1516.95 (347), p < 0.001, normed chi-square (X2/df ) = 4.37, RMSEA = 0.106, SRMR = 0.079, and CFI = 0.735. The Indonesian version of the NPVS3 showed good internal consistency with Cronbach’s alphas for the instrument of 0.97 and 0.94, 0.95, and 0.89 for Caring, Activism, and Professionalism, respectively. The Indonesian version of the NPVS-3 is valid and reliable for use in Indonesia.
