To look at the characteristics of Postgraduate Hospital Educational Environment Measure (PHEEM) using data from the UK, Brazil, Chile and the Netherlands, and to examine the reliability and characteristics of PHEEM, especially how the three PHEEM subscales fitted with factors derived statistically from the data sets.
Statistical analysis of PHEEM scores from 1563 sets of data, using reliability analysis, exploratory factor analysis and correlations of factors derived with the three defined PHEEM subscales.
PHEEM was very reliable with an overall Cronbach's alpha of 0.928. Three factors were derived by exploratory factor analysis. Factor One correlated most strongly with the teaching subscale (R = 0.802), Factor Two correlated most strongly with the role autonomy subscale (R = 0.623) and Factor Three correlated most strongly with the social support subscale (R = 0.538).
PHEEM is a multi-dimensional instrument. Overall, it is very reliable. There is a good fit of the three defined subscales, derived by qualitative methods, with the three principal factors derived from the data by exploratory factor analysis.
利用来自英国、巴西、智利和荷兰的数据，观察研究生医院教育环境量表（PHEEM）的特点，并检验 PHEEM 的可靠性和特征，特别是三个 PHEEM 分量表如何与从数据集统计得出的因子拟合。
对来自 1563 组数据的 PHEEM 评分进行统计分析，使用可靠性分析、探索性因子分析以及与三个定义的 PHEEM 分量表相关的因子相关性分析。
PHEEM 具有非常高的可靠性，总体 Cronbach's alpha 为 0.928。通过探索性因子分析得出了三个因子。因子一与教学分量表相关性最强（R = 0.802），因子二与角色自主性分量表相关性最强（R = 0.623），因子三与社会支持分量表相关性最强（R = 0.538）。
PHEEM 是一个多维工具。总体而言，它具有很高的可靠性。通过探索性因子分析从数据中得出的三个主要因子与通过定性方法得出的三个定义的分量表非常吻合。
