The practice environment pivotal role in patients and nurses better outcomes is evident. Practice Environment Scale of Nursing Work Index (PES-NWI) is widely utilized to assess nursing work environments. The present study was conducted to demonstrate the validity and reliability of the Persian version of PES-NWI.
The instrument was translated and its psychometrics were investigated by content, construct validity (factor analysis), and homogeneity (internal consistency and intraclass correlation) on a sample of 350 nurses at educational hospitals in East Azerbaijan, Iran.
The 30 items loaded onto 4 factors explained 34.95-50.06% of the variance. The items across the factors differed slightly from those reported by the original author of the PES-NWI. Cronbach's alpha and Pearson coefficient for the entire instrument and also for extracted factors was 0.70-0.96.
The Persian version of PES-NWI has an appropriate level of validity and reliability in the Iranian setting for nurses. The subscale of Nursing Foundations for quality care needs modification.
实践环境在患者和护士获得更好结局方面的关键作用是显而易见的。护理工作指数实践环境量表（PES-NWI）被广泛用于评估护理工作环境。本研究旨在验证波斯语版PES-NWI的有效性和可靠性。
对该工具进行翻译，并通过内容效度、结构效度（因子分析）和同质性（内部一致性和组内相关），在伊朗东阿塞拜疆省教学医院的350名护士样本中对其心理测量学特性进行研究。
30个条目加载到4个因子上，解释了34.95%-50.06%的方差。各因子中的条目与PES-NWI原作者报告的条目略有不同。整个工具以及提取因子的克朗巴哈α系数和皮尔逊系数为0.70-0.96。
波斯语版PES-NWI在伊朗环境中对护士具有适当水平的有效性和可靠性。优质护理的护理基础子量表需要修改。
