This study is to evaluate the psychometric properties of the Korean version of the Self-Efficacy of Evidence-Based Practice (SE-EBP) scale, which was originally developed by Chang and Crowe. The beta-version of the SE-EBP is a modified version of the original SE-EBP, which measures the clinical nurses' confidence in finding, appraising, and implementing evidence into practice. Although the original SE-EBP has been validated, no study has been conducted to validate the Korean version of SE-EBP.
The original scale was translated into Korean through a process of forward and back translation of the original scale. After getting confirmation of the equivalence of the Korean forward translation by the original author, exploratory factor analysis and confirmatory factor analysis of data from 212 clinical nurses were used to test construct validity. Internal consistency was examined using Cronbach α coefficients. For the statistical analysis, STATA version 13.0 software program was used.
Exploratory factor analysis of the 28 items revealed three factors with eigenvalues above 1, accounting for 60.2% of the total variance. Confirmatory factor analysis showed good fit of the three-factor structure which was statistically significant (χ=718.61, df=330, p<.01). For internal consistency, Cronbach α coefficient for the total scale was .95, and it was greater than .80 for each of the three subscales.
The Korean version of SE-EBP scale showed evidence of adequate construct validity and reliability. This study might have contributed to a wider application of the SE-EBP scale, but further studies are needed to provide more evidence on the structure of the scale.
本研究旨在评估由Chang和Crowe最初开发的循证实践自我效能感（SE-EBP）量表韩文版的心理测量特性。SE-EBP的beta版是原始SE-EBP的修订版，用于测量临床护士在查找、评估和将证据应用于实践方面的信心。尽管原始的SE-EBP已得到验证，但尚未有研究对SE-EBP韩文版进行验证。
通过对原始量表进行正向和反向翻译的过程，将原始量表翻译成韩文。在获得原始作者对韩文正向翻译等效性的确认后，使用来自212名临床护士的数据进行探索性因素分析和验证性因素分析，以检验结构效度。使用Cronbach α系数检验内部一致性。统计分析使用STATA 13.0软件程序。
对28个项目的探索性因素分析揭示了三个特征值大于1的因素，占总方差的60.2%。验证性因素分析表明三因素结构拟合良好，具有统计学意义（χ=718.61，df=330，p<.01）。在内部一致性方面，总量表的Cronbach α系数为0.95，三个子量表各自的系数均大于0.80。
SE-EBP量表韩文版显示出足够的结构效度和信度证据。本研究可能有助于SE-EBP量表的更广泛应用，但需要进一步研究以提供关于该量表结构的更多证据。
