Low self-efficacy is a barrier to effective nurse prescribing. Therefore, nurses' self-efficacy should be assessed using validated tools. We aimed to develop and psychometrically test the Nurse Prescribing Self-Efficacy Scale (NP-SES). We conducted an observational cross-sectional study with 290 nurses between January and June 2019. We studied the NP-SES' reliability (i.e., internal consistency and temporal stability), validity (i.e., content, criterion, and construct) and legibility. The NP-SES showed good internal consistency (Cronbach's alpha=0.958) and temporal stability (intraclass correlation coefficient=0.783). The NP-SES also showed good content validity (scale's content validity index=0.98) and criterion validity (=0.75; p<0.001). Construct validity analysis revealed the NP-SES' three-dimensional structure and showed its ability to detect significant differences between nurses with different levels of experience. Our psychometric analysis suggests that the NP-SES is a reliable and valid instrument that could be used to assess nurses' self-efficacy in nurse prescribing.
自我效能感低是有效实施护士处方权的一个障碍。因此，应使用经过验证的工具来评估护士的自我效能感。我们旨在开发并对护士处方自我效能量表（NP-SES）进行心理测量学测试。2019年1月至6月，我们对290名护士进行了一项观察性横断面研究。我们研究了NP-SES的信度（即内部一致性和时间稳定性）、效度（即内容效度、效标效度和结构效度）以及易读性。NP-SES表现出良好的内部一致性（克朗巴哈系数=0.958）和时间稳定性（组内相关系数=0.783）。NP-SES还表现出良好的内容效度（量表的内容效度指数=0.98）和效标效度（=0.75；p<0.001）。结构效度分析揭示了NP-SES的三维结构，并显示出其能够检测出不同经验水平护士之间的显著差异。我们的心理测量学分析表明，NP-SES是一种可靠且有效的工具，可用于评估护士在处方权方面的自我效能感。
