# Testing reliability and validity of the Korean version of Debriefing Assessment for Simulation in Healthcare (K-DASH)

## TL;DR

This study developed and validated a Korean version of the DASH-SV tool to assess debriefing in healthcare education for nursing students.

## Contribution

The paper introduces a validated Korean version of the DASH-SV with confirmed reliability and validity for use in Korean healthcare education.

## Key findings

- The Korean DASH-SV showed acceptable content validity with high item and scale CVI scores.
- Exploratory and confirmatory factor analyses supported a unidimensional structure with six significant items.
- The tool demonstrated good internal consistency with a Cronbach’s alpha of 0.82.

## Abstract

Use of the Debriefing Assessment for Simulation in Healthcare (DASH©) would be beneficial for novice debriefers with less or no formal training in debriefing. However, the DASH translated into Korean and tested for psychometrics is not yet available. Thus, this study was to develop a Korean version of the DASH student version (SV) and test its reliability and validity among baccalaureate nursing students in Korea.

The participants were 99 baccalaureate nursing students. Content validity using content validity index (CVI), construct validity using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and internal consistency using Cronbach’s alpha coefficient were assessed.

Both Item-CVIs and Scale-CVI were acceptable. EFA supported the unidimensional latent structure of Korean DASH-SV and results of CFA indicated 6 items converged within the extracted factor, significantly contributing to the factor (p ≤ .05). Items were internally consistent (Cronbach’s α = 0.82).

The Korean version of the DASH-SV is arguably a valid and reliable measure of instructor behaviors that could improve faculty debriefing and student learning in the long term.
