This article reports on construct validity and reliability of 30 items of the Practice Environment Scale of the Nursing Work Index (PES-NWI). Australia, like other countries, is experiencing a shortage of nurses; a multifactor approach to retention of nurses is required. One significant factor that has received increasing attention in the last decade, particularly in the USA, is the nursing practice environment. The reliability of the 30 items of the PES-NWI was assessed by Cronbach's alpha and factor analysis was performed using principal component analysis. The PES-NWI was completed by nurses working in the aged-care, private and public sectors in Queensland, Australia. A total of 3000 surveys were distributed to a random sample of members of the Queensland Nurses Union. Of these, 1192 surveys were returned, a response rate of 40%. The PES-NWI was shown to be reliable demonstrating internal consistency with a Cronbach's alpha of the total scale of 0.948. The 30 items loaded onto five factors explaining 57.7% of the variance. The items across the factors differed slightly from those reported by the original author of the PES-NWI. This study indicates that the PES-NWI has construct validity and reliability in the Australian setting for nurses.
本文报告了护理工作指数实践环境量表（PES-NWI）30个条目的结构效度和信度。与其他国家一样，澳大利亚正面临护士短缺的问题；需要采取多因素方法来留住护士。在过去十年中，尤其是在美国，一个受到越来越多关注的重要因素是护理实践环境。通过克朗巴哈系数评估了PES-NWI 30个条目的信度，并使用主成分分析进行了因子分析。PES-NWI由在澳大利亚昆士兰州老年护理、私立和公立部门工作的护士完成。总共向昆士兰护士联盟成员的随机样本发放了3000份调查问卷。其中，1192份问卷被收回，回复率为40%。结果显示，PES-NWI具有信度，总量表的克朗巴哈系数为0.948，表明其内部一致性良好。30个条目加载到五个因子上，解释了57.7%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。本研究表明，PES-NWI在澳大利亚护士群体中具有结构效度和信度。
