Identification of semester-specific teaching contents for dental ethics: development, testing and validation of a questionnaire

摘要

Although medical ethics is an indispensable part of dental education, it has not played a relevant role in the dental curriculum thus far. This study is aimed at developing and validating a questionnaire that identifies semester-specific ethical issues, in order to develop longitudinal ethic modules. March 2018 a workshop on item generation was coordinated, using Delphi method; followed by a cognitive testing with students (2nd, 4th, 10th semesters, n?=?12). A pilot test was carried out with students from different semesters (n?=?60). The distribution of response frequencies and missing values were determined. The questionnaire used for validation consisted of three dimensions: ethical knowledge, dealing with ethical issues, expectations in terms of teaching. The psychometric examination was carried out by preclinical students (n?=?105) and clinical semesters (n?=?110) January 2019. After cognitive testing and piloting, some items were reformulated, so that a questionnaire with 127 items was used for validation. The individual dimensions were assigned to various factors with excellent to acceptable internal consistency (Cronbach’s α 0.72–0.96). The questionnaire has an acceptable to excellent consistency and suggests that the different dimensions are conclusive. With this questionnaire, ethical issues in dentistry can be mapped and teaching contents identified.
