The aim of this study was to develop and validate according to psychometric standards a self-administered instrument to measure the students' self-perceptions of the undergraduate clinical dental environment (DECLEI).
The initial questionnaire was developed using feedback from dental students, experts' opinion and an extensive literature review. Critical incident technique (CIT) analysis was used to generate items and identify domains. Thirty clinical dental students participated in a pilot validation that generated a 67-item questionnaire. To develop a shorter and more practical version of the instrument, DECLEI-67 was distributed to 153 clinical students at the University of Athens and its English version to 51 students from various dental schools, attending the 2012 European Dental Students Association meeting. This final procedure aimed to select items, identify subscales and measure internal consistency and discriminant validity.
A total of 202 students returned the questionnaires (response rate 99%). The final instrument included 24 items divided into three subscales: (i) organisation and learning opportunities, (ii) professionalism and communication and (iii) satisfaction and commitment to the dental studies. Cronbach's α for the total questionnaire was 0.89. The interscale correlations ranged from 0.39 to 0.48. The instrument identified differences related to school of origin, age and duration of clinical experience. An interpretation of the scores (range 0–100) has been proposed.
The 24-item DECLEI seemed to be a practical and valid instrument to measure a dental school's undergraduate clinical learning environment.
本研究的目的是根据心理测量标准开发并验证一种用于测量学生对本科临床牙科环境自我认知的自填式工具（DECLEI）。
初始问卷的开发采用了牙科学生的反馈、专家意见以及广泛的文献综述。采用关键事件技术（CIT）分析来生成项目并确定领域。30名临床牙科学生参与了预试验验证，生成了一份包含67个条目的问卷。为了开发一个更简短、更实用的版本，将DECLEI - 67分发给雅典大学的153名临床学生，并将其英文版本分发给参加2012年欧洲牙科学生协会会议的来自不同牙科学院的51名学生。这最后一步旨在选择条目、确定子量表并测量内部一致性和区分效度。
共有202名学生返回了问卷（回复率99%）。最终工具包括24个条目，分为三个子量表：（i）组织与学习机会，（ii）专业素养与沟通，（iii）对牙科学习的满意度与投入度。整个问卷的Cronbach's α系数为0.89。各子量表间的相关性在0.39至0.48之间。该工具识别出了与生源学校、年龄和临床经验时长相关的差异。已提出了分数（范围0 - 100）的解释。
24个条目的DECLEI似乎是一种用于测量牙科学院本科临床学习环境的实用且有效的工具。
