Rubber dam isolation is considered as an essential component of modern adhesive dentistry. However, dental students do not always use it due to several barriers they face on their clinical practice. The aim of this study was to design and validate a questionnaire based on the COM-B model to measure students' implementation of rubber dam isolation in restorative treatments with adhesive materials.
A 7-item questionnaire was developed based on the COM-B model, with questions measuring the Capability, Opportunity (Relevance and Resources), and Motivation to perform rubber dam isolation (Behaviour). Content validation of the questionnaire was conducted by experts in aesthetic/restorative dentistry that assessed the clarity, coherence and relevance of the questions. The final survey was administered to a dental student population from three large private universities in the Dominican Republic. Descriptive analysis, t tests, polychoric correlations and a path analysis were carried out to establish the validity of the instrument.
A total of 382 students from three universities completed the questionnaire. According to the COM-B path model, the significant predictors of the implementation of rubber dam isolation were Capability and Motivation for University A, Motivation and Opportunity-Resources for University B, and Opportunity-Relevance and Capability for University C.
The RDIS is a very short, easy to administer and valid questionnaire that can be applied by the universities to determine where they need to focus their interventions to achieve better rubber dam isolation implementation by their students.
橡胶坝隔离被认为是现代黏附性牙科的重要组成部分。然而，由于学生在临床实践中面临的诸多障碍，他们并不总是使用它。本研究的目的是设计并验证基于 COM-B 模型的问卷，以衡量学生在使用黏附性材料进行修复治疗时实施橡胶坝隔离的情况。
根据 COM-B 模型，开发了一个包含 7 个问题的问卷，这些问题衡量了实施橡胶坝隔离的能力、机会（相关性和资源）和动机（行为）。问卷的内容有效性由美学/修复牙科专家进行评估，以评估问题的清晰度、连贯性和相关性。最终的调查针对来自多米尼加共和国三所大型私立大学的牙科学生群体进行。为了确定该工具的有效性，进行了描述性分析、t 检验、多元相关分析和路径分析。
共有来自三所大学的 382 名学生完成了问卷。根据 COM-B 路径模型，对橡胶坝隔离实施的显著预测因素为大学 A 的能力和动机、大学 B 的动机和机会-资源以及大学 C 的机会-相关性和能力。
RDIS 是一个非常简短、易于管理且有效的问卷，各大学可以使用它来确定他们需要在哪些方面进行干预，以提高学生实施橡胶坝隔离的能力。
