Abstract

OBJECTIVES

To develop and test the psychometric properties (validity and reliability) of a questionnaire to evaluate clinical dental teachers.

METHODS

An item (question) pool was generated with the use of a literature review, feedback from faculty staff, and from focus group discussions with dental students. Following factor analysis the validity and reliability of a revised questionnaire was assessed. This involved 148 dental students and 453 assessments of 29 clinical dental teachers.

RESULTS

Effective clinical dental teaching (ECDT) scores were associated with 'global ratings' of the effectiveness of clinical dental teaching (P<0.01), indicating strong criterion validity. In comparison analysis there was strong agreement between students regarding ratings of individual clinical dental teachers, indicating good construct validity. Reliability was assessed by examining internal consistency of sub-scales and overall ECDT scale, and found to be good (Cronbach alpha's > 0.80).

CONCLUSION

A valid and reliable measure to evaluate clinical dental teachers has been developed for use in a clinical academia setting, and has potential use as a quality assurance measure.

摘要

目的

开发并测试一份用于评估临床牙科教师的问卷的心理测量特性（效度和信度）。

方法

通过文献综述、教职员工的反馈以及与牙科学生的焦点小组讨论生成一个项目（问题）池。经过因子分析后，对修订后的问卷的效度和信度进行评估。这涉及148名牙科学生以及对29名临床牙科教师的453次评估。

结果

有效的临床牙科教学（ECDT）得分与临床牙科教学有效性的“总体评分”相关（P<0.01），表明具有很强的效标效度。在比较分析中，学生们对个别临床牙科教师的评分之间存在很强的一致性，表明具有良好的结构效度。通过检查子量表和总体ECDT量表的内部一致性来评估信度，发现信度良好（克朗巴哈系数>0.80）。
