To describe the Professional Practice Environment (PPE) scale, its conceptual development and psychometric evaluation, and its uses in measuring eight characteristics of the professional practice environment in an acute care setting.
The 38-item PPE Scale was validated on a sample of 849 professional practice staff at the Massachusetts General Hospital in Boston. Psychometric analysis included: item analysis, principal components analysis (PCA) with varimax rotation and Kaiser normalization, and internal consistency reliability using Cronbach's alpha coefficient.
Eight components were shown, confirming the original conceptually derived model's structure and accounting for 61% of explained variance. Cronbach's alpha coefficients for the eight PPE subscales ranged from .78 to .88.
Findings showed the 38-item PPE Scale was reliable and valid for use in health outcomes research to examine the professional practice environment of staff working in acute care settings.
描述专业实践环境(PPE)量表、其概念发展和心理测量学评估,以及它在测量急性护理环境中专业实践环境的八个特征方面的用途。
38项PPE量表在波士顿麻省总医院的849名专业实践人员样本上进行了验证。心理测量学分析包括:项目分析、采用方差最大化旋转和凯泽标准化的主成分分析(PCA),以及使用克朗巴赫α系数的内部一致性信度分析。
显示出八个组成部分,证实了最初概念推导模型的结构,并解释了61%的方差。八个PPE子量表的克朗巴赫α系数范围为0.78至0.88。
研究结果表明,38项PPE量表在健康结果研究中用于检查急性护理环境中工作人员的专业实践环境是可靠且有效的。
