The Reliability and Validity of the Korean Version of the Indiana University Simulation Integration Rubric for Interprofessional Communication among Nursing and Medical Students

Purpose: This study aimed to translate and validate the Korean version of the Indiana University Simulation Integration Rubric (K-IUSIR) for assessing interprofessional communication in simulation-based education, focusing on its reliability and validity. Background: Interprofessional education (IPE) improves communication and teamwork skills critical for ensuring patient safety. However, there is a lack of standardized tools for assessing interprofessional communication in Korea.Methods: A methodological study involving a secondary analysis was conducted with 221 nursing and medical students. Data were collected through simulation recordings and surveys and analyzed using Cronbach’s ⍺, intraclass correlation coefficients (ICCs), expert content validity, and Rasch analysis.Results: The K-IUSIR demonstrated high internal consistency (Cronbach’s ⍺=0.854), inter-rater reliability (ICC=0.832), and strong content validity. Rasch analysis confirmed appropriate item fit and difficulty levels, with a 3-point Likert scale identified as the most suitable format.Conclusion: The K-IUSIR is a reliable and valid tool for evaluating interprofessional communication, which can be utilized in developing interprofessional education programs. Furthermore, it can facilitate better interprofessional collaboration through effective communication.
