Validation of the Korean Version of the Nursing Profession Self-Efficacy Scale: A Methodological Study

Abstract

Background: The Nursing Profession Self-Efficacy (NPSE) scale was developed to reflect the characteristics of nursing tasks. This study was conducted to validate the Korean version of the NPSE (K-NPSE) scale. Methods: The NPSE scale with nineteen items was translated into Korean after forward and backward translation according to Devellis’ guideline. For the exploratory factor analysis (EFA), 298 nurses participated and criterion-related validity and reliability were verified. For the confirmatory factor analysis (CFA), 218 other nurses participated. Content validity, criterion-related validity, and internal consistency reliability were examined. Additionally, construct validity was examined. SPSS and AMOS were used for the data analyses. Results: Nineteen items were selected after evaluating the content and cognitive validity and comprised three factors: “Professional (10 items)”, “Advocating (4)”, and “Caring (5)”. Construct validity was supported by the CFA. Criterion-related validity was supported by comparison with the General Self-Efficacy Test (r = 0.43, p < 0.001). Cronbach’s alpha of the K-NPSE was 0.93. Conclusions: Study findings indicate that the K-NPSE could be useful for assessing nurses’ self-efficacy. The K-NPSE may be used as a valuable reference for developing programs or policies that promote nursing professionals. It is expected that continued use of this scale in various clinical settings to further generalize and validate the scale.

Psychometric Properties of the Albanian Version of the Nursing Self-Efficacy Scale

“…The original NPSES developed by Caruso et al (2016) [ 24 ] includes two factors: ‘quality of service’ and nursing ‘professional situations’; these factors measure the skills nurses need to work in professional ways. Our study is more similar to a previous study located in Korea [ 45 ] and defined four factors in the A-NPSES.…”

“…We developed a fit model using CFA that showed that a four-factor structure explained the data collected from our reference sample better than the original two-factor model. Surely, the differences in the characteristics of the sample analyzed and the different cultural contexts are attributable to different nursing environments and may explain the differences in the structure of the factors, as they also indicated in the study of the Korean researchers, where even the structure of NPSES in the Korean context was to four factors [ 45 ].…”

Development and Validation of a Self-Efficacy Scale for Nursing Educators’ Role in Sri Lanka

“…The following are considered the reasons for this result: First, although 150 participants were considered eligible to participate, only 126 participants were included in this study. Second, to ensure the accuracy of CFA analysis, independent collection of data that do not overlap with EFA data is required [43,44]. However, the same data were analyzed for both CFA and EFA in this study.…”

An Observational Cross-Sectional Study on the Correlation between Professional Competencies and Self-Efficacy in Albanian Registered Nurses

“…Although having specific scales is vital to exploring the specific relationships between task-specific self-efficacy and related outcomes, having a broader measure of nursing self-efficacy is also essential when establishing a relationship with broader outcomes (e.g., stress, burnout, and job dissatisfaction) and requires further research [19]. The most widely used self-report scale is the Nursing Profession Self-Efficacy Scale (NPSES), developed in 2016 and translated into several languages (e.g., Korean, Albanian, Turkish) [20][21][22].…”
