Reliability and validity of Korean version of DASH(Debriefing Assessment for Simulation in Healthcare) for simulation in learning: Mixed study

Abstract

Objectives Debriefing is the core of simulation education that helps learners to meaningfully structure their experience. A valid and reliable scale capable of evaluating debriefing in Korean culture is required. This study translated the Debriefing Assessment for Simulation in Healthcare (DASH), into Korean, and analyzed its validity and reliability. Methods A total of 66 participants from nursing colleges in 3 different regions evaluated the tools and 4 participated via in-depth interviews. Results A one-factor model showed acceptable fit indices (χ2=20.21, χ2/df=2.25, comparative fit index=.95, standardized root mean square residual=.05, normed fit index=.91, tucker-lewis index=.92, root mean square error of approximation=.15). Via in-depth interviews, using K-DASH was identified to helped in successful debriefing. Cronbach’s α was .94. Conclusions This study demonstrated acceptable validity and reliability of K-DASH and its introduction into the Korean simulation curriculum can improve the efficacy of simulation education.
