To undertake rigorous psychometric testing of the newly developed contemporary work environment measure (the Brisbane Practice Environment Measure [B-PEM]) using exploratory factor analysis and confirmatory factor analysis.
Content validity of the 33-item measure was established by a panel of experts. Initial testing involved 195 nursing staff using principal component factor analysis with varimax rotation (orthogonal) and Cronbach's alpha coefficients. Confirmatory factor analysis was conducted using data from a further 983 nursing staff.
Principal component factor analysis yielded a four-factor solution with eigenvalues greater than 1 that explained 52.53% of the variance. These factors were then verified using confirmatory factor analysis. Goodness-of-fit indices showed an acceptable fit overall with the full model, explaining 21% to 73% of the variance. Deletion of items took place throughout the evolution of the instrument, resulting in a 26-item, four-factor measure called the Brisbane Practice Environment Measure-Tested.
The B-PEM has undergone rigorous psychometric testing, providing evidence of internal consistency and goodness-of-fit indices within acceptable ranges. The measure can be utilised as a subscale or total score reflective of a contemporary nursing work environment.
An up-to-date instrument to measure practice environment may be useful for nursing leaders to monitor the workplace and to assist in identifying areas for improvement, facilitating greater job satisfaction and retention.
采用探索性因子分析和验证性因子分析对新开发的当代工作环境测量工具（布里斯班实践环境测量工具[B-PEM]）进行严格的心理计量学测试。
通过专家小组确定 33 项测量的内容效度。初步测试涉及 195 名护理人员，使用主成分因子分析和方差极大旋转（正交）以及克朗巴赫的α系数。使用另外 983 名护理人员的数据进行验证性因子分析。
主成分因子分析产生了一个具有大于 1 的特征值的四因子解，解释了 52.53%的方差。然后使用验证性因子分析验证了这些因子。整体而言，拟合优度指数显示出较好的拟合度，全模型解释了 21%至 73%的方差。通过对仪器的不断改进，删除了一些项目，形成了一个 26 项、四因子的测量工具，称为布里斯班实践环境测量工具-测试版。
B-PEM 已经经过了严格的心理计量学测试，提供了内部一致性和拟合优度指数的证据，这些指数在可接受的范围内。该测量工具可以作为一个子量表或总分来反映当代护理工作环境。
一种最新的测量实践环境的工具对于护理领导者来说可能是有用的，它可以帮助监测工作场所，并有助于确定需要改进的领域，从而提高工作满意度和保留率。
