To assess the psychometric properties regarding the Portuguese version of the Practice Environment Scale of the Nursing Work Index.
The Practice Environment Scale of the Nursing Work Index is the most widely used measure for assessing the practice environment. A model with a higher number of factors appears to be more adequate to Portuguese settings.
A confirmatory factor analysis was performed to the Practice Environment Scale of the Nursing Work Index using a sample of 850 Portuguese nurses. Three models were tested: the original model, a seven-factor model and a higher-order model. An analysis of invariance was performed in two subsets to confirm the stability of the solution.
The seven-factor model fit better to the data than the original model. After refinement, this solution showed suitability and a stable factor structure. Reliability, convergent validity and discriminant validity were confirmed. A second-order factor solution also showed suitability.
The seven-factor structure of the Practice Environment Scale of the Nursing Work Index showed a better goodness-of-fit to Portuguese settings than the original structure. The second-order factor solution allows an overall assessment of practice environments.
The Portuguese version of the Practice Environment Scale of the Nursing Work Index is a valuable tool for assessing Portuguese nursing practice environments. The seven-factor solution of the Practice Environment Scale of the Nursing Work Index showed high specificity.
评估护理工作指数实践环境量表葡萄牙语版本的心理测量特性。
护理工作指数实践环境量表是评估实践环境最广泛使用的工具。一个具有更多因素的模型似乎更适合葡萄牙的情况。
使用850名葡萄牙护士的样本对护理工作指数实践环境量表进行验证性因素分析。测试了三个模型：原始模型、七因素模型和高阶模型。在两个子集中进行了不变性分析以确认解决方案的稳定性。
七因素模型比原始模型更适合数据。经过优化后，该解决方案显示出适用性和稳定的因素结构。可靠性、收敛效度和区分效度得到了确认。二阶因素解决方案也显示出适用性。
护理工作指数实践环境量表的七因素结构比原始结构更适合葡萄牙的情况。二阶因素解决方案允许对实践环境进行整体评估。
护理工作指数实践环境量表的葡萄牙语版本是评估葡萄牙护理实践环境的宝贵工具。护理工作指数实践环境量表的七因素解决方案显示出高特异性。
