Self-efficacy in the nursing profession has been reported to have a positive effect on personal performance in terms of clinical performance and decision-making abilities, nursing performance, professional intuition, organizational commitment, and turnover intention.
The purpose of this study was to verify the validity and reliability of the Korean version of the Nursing Profession Self-Efficacy Scale (K-NPSES).
This methodological study used questionnaires collected from 307 nurses at medical institutions in South Korea. The content validity of the questionnaire was verified using the averaging method, whereas the criterion-related validity was evaluated by calculating the correlation with the Sherer General Self-Efficacy Scale. The construct validity was determined by analyzing the explanatory and confirmatory factors. Reliability was verified using Cronbach's α and test-retest by calculating intraclass correlation coefficients.
The content validity index of the K-NPSES was found to be greater than .95, and the criterion-related validity was satisfactory (coefficient = .57, p < .001). The original Nursing Profession Self-Efficacy Scale has two subfactors, and the K-NPSES analyzed in this study has four subfactors. The data were appropriate for factor analysis using Kaiser-Meyer-Olkin (.87) and Bartlett's sphericity test (χ2 = 1236.01, df = 137, p < .001). The model fit was acceptable (normed chi-square [χ2/df] = 2.22, root mean square residual = .05, root mean square error of approximation = .09, comparative fit index = .88, Tucker-Lewis index = .86, goodness-of-fit index = .83). Regarding reliability, Cronbach's α was .91 and the intraclass correlation coefficient was .78 (p < .001).
CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The findings of this study confirmed the K-NPSES as having acceptable validity. In addition to predicting nursing clinical performance, a well-established nursing profession self-efficacy scale may be used to improve the quality of clinical nursing.
自我效能感在护理专业中被报道对个人表现具有积极影响，包括临床表现和决策能力、护理绩效、专业直觉、组织承诺和离职意向。
本研究旨在验证韩国版护理职业自我效能量表（K-NPSES）的效度和信度。
本方法学研究使用问卷收集了韩国医疗机构的 307 名护士的数据。使用平均法验证问卷的内容效度，通过计算与 Sherer 一般自我效能感量表的相关性来评估效标关联效度。通过分析解释和验证性因素来确定构念效度。使用 Cronbach's α 和计算组内相关系数的重测信度来验证信度。
K-NPSES 的内容效度指数大于.95，效标关联效度令人满意（系数=.57，p <.001）。原始护理职业自我效能量表有两个亚因素，本研究分析的 K-NPSES 有四个亚因素。数据适合使用 Kaiser-Meyer-Olkin（.87）和 Bartlett 球形检验（χ2 = 1236.01，df = 137，p <.001）进行因子分析。模型拟合可接受（标准化卡方比 [χ2/df] = 2.22，均方根残差 =.05，近似均方误差 =.09，比较拟合指数 =.88，Tucker-Lewis 指数 =.86，拟合优度指数 =.83）。关于信度，Cronbach's α 为.91，组内相关系数为.78（p <.001）。
结论/对实践的启示：本研究结果证实了 K-NPSES 具有可接受的效度。除了预测护理临床绩效外，一个成熟的护理职业自我效能量表还可以用于提高临床护理质量。
