Clinical learning takes place in complex socio-cultural environments that are workplaces for the staff and learning places for the students. In the clinical context, the students learn by active participation and in interaction with the rest of the community at the workplace. Clinical learning occurs outside the university, therefore is it important for both the university and the student that the student is given opportunities to evaluate the clinical placements with an instrument that allows evaluation from many perspectives. The instrument Clinical Learning Environment and Supervision (CLES) was originally developed for evaluation of nursing students' clinical learning environment. The aim of this study was to adapt and validate the CLES instrument to measure medical students' perceptions of their learning environment in primary health care.
In the adaptation process the face validity was tested by an expert panel of primary care physicians, who were also active clinical supervisors. The adapted CLES instrument with 25 items and six background questions was sent electronically to 1,256 medical students from one university. Answers from 394 students were eligible for inclusion. Exploratory factor analysis based on principal component methods followed by oblique rotation was used to confirm the adequate number of factors in the data. Construct validity was assessed by factor analysis. Confirmatory factor analysis was used to confirm the dimensions of CLES instrument.
The construct validity showed a clearly indicated four-factor model. The cumulative variance explanation was 0.65, and the overall Cronbach's alpha was 0.95. All items loaded similarly with the dimensions in the non-adapted CLES except for one item that loaded to another dimension. The CLES instrument in its adapted form had high construct validity and high reliability and internal consistency.
CLES, in its adapted form, appears to be a valid instrument to evaluate medical students' perceptions of their clinical learning environment in primary health care.
临床学习发生在复杂的社会文化环境中,这些环境既是工作人员的工作场所,也是学生的学习场所。在临床环境中,学生通过积极参与以及与工作场所中的其他群体互动来学习。临床学习在大学之外进行,因此对于大学和学生而言,给予学生机会使用一种能从多个角度进行评估的工具来评价临床实习点非常重要。临床学习环境与监督量表(CLES)最初是为评估护理专业学生的临床学习环境而开发的。本研究的目的是对CLES量表进行改编和验证,以测量医学生对其在初级卫生保健中学习环境的认知。
在改编过程中,由基层医疗医生组成的专家小组对内容效度进行了测试,这些医生同时也是活跃的临床带教老师。将改编后的包含25个项目和6个背景问题的CLES量表以电子方式发送给一所大学的1256名医学生。394名学生的答案符合纳入标准。采用基于主成分法并进行斜交旋转的探索性因素分析来确定数据中因素的适当数量。通过因素分析评估结构效度。采用验证性因素分析来确认CLES量表的维度。
结构效度显示出一个明确的四因素模型。累积方差解释率为0.65,总体Cronbach's α系数为0.95。除一项加载到另一个维度外,所有项目与未改编的CLES量表维度的加载情况相似。改编后的CLES量表具有较高的结构效度、信度和内部一致性。
改编后的CLES量表似乎是评估医学生对其在初级卫生保健中临床学习环境认知的有效工具。
