Assessing the Development and Validity of Educational Videos in Educating Dental Infection Control Coordinators

This study aimed to introduce video-recorded simulation-based scenarios to facilitate case-based learning discussions (CBLDs) and to evaluate the appropriateness of these educational videos for hands-on training by conducting an expert validation process.

Following educational video topics were chosen based on their practicality and high demand from the dental infection control coordinators (DICC): "Reprocessing and Sterilization Monitoring of Reusable Instruments," "Performance Monitoring of Infection Control Specialists," "Hand Hygiene and Personal Protective Equipment (PPE)," and "Reporting System and Post-Incident Management for Infection Exposures." Scenario development involved five dental hygienists with > 10 years of experience. To evaluate the effectiveness of the video, surveys were conducted with 25 individuals with > 5 years of experience in the field. Construct validity was assessed using exploratory factor analysis and internal consistency with Cronbach's α.

Ten educational videos were developed (2-3 videos per topic). Regarding internal consistency reliability, Cronbach's α values for each of the four topics were all greater than 0.9. Factor analysis of all 34 items yielded five factors that collectively explained 86.201% of the variance. Concerning the "overall educational satisfaction score," high ratings were obtained for "extensive coverage of dental clinical infection control content within each topic" and "appropriateness of the educational material for training in dental infection control management."

The developed videos for dental infection control were reliable and suitable for educating DICC. These videos are expected to hold significant importance in situations where face-to-face and hands-on training pose difficulties.
