In this study, a psychometric evaluation of the Nurse Practitioner Self-efficacy Scale (NPSES) was conducted.
Self-efficacy is an important concept for optimal nurse practitioner (NP) performance and retention. The NPSES may serve as a valuable instrument to support NP practice.
This descriptive cross-sectional study evaluated the NPSES responses from 230 NPs. Confirmatory factor analysis, reliability, and t tests were used to analyze the results.
Confirmatory factor analysis revealed acceptable goodness of fit for an 8-factor model (root-mean-square error of approximation = 0.05, comparative fit index = 0.97, Tucker Lewis index = 0.96). Reliability estimates resulted in acceptable internal consistency (coefficient α = 0.94). The t tests comparing more and less experienced NPs resulted in higher scores in more experienced NPs.
This validation study showed that the NPSES is a psychometrically-sound instrument to assess NP self-efficacy. The NPSES is a cost-effective and convenient method to measure self-efficacy, a valuable concept for NP practice.
本研究对护士从业者自我效能感量表（NPSES）进行了心理计量学评估。
自我效能感是护士从业者（NP）最佳表现和保留的重要概念。NPSES 可能是支持 NP 实践的有价值工具。
本描述性横断面研究评估了 230 名 NP 的 NPSES 反应。采用验证性因子分析、可靠性和 t 检验来分析结果。
验证性因子分析显示，8 因素模型具有可接受的拟合优度（近似均方根误差=0.05，比较拟合指数=0.97，塔克-刘易斯指数=0.96）。可靠性估计得出可接受的内部一致性（系数α=0.94）。比较经验更丰富和经验较少的 NP 的 t 检验显示，经验更丰富的 NP 的得分更高。
这项验证性研究表明，NPSES 是评估 NP 自我效能感的心理计量学上合理的工具。NPSES 是衡量自我效能感的一种具有成本效益且方便的方法，自我效能感是 NP 实践的一个有价值的概念。
