Effects of a transformative learning theory based debriefing in simulation: A randomized trial

Debriefing, based on reflection, is imperative in simulation. Mezirow's transformative learning theory (TLT) uses critical reflection in providing care to patients, which involves clinical judgment in nursing. The aim of this study was to compare the effects of TLT-versus a non-TLT-based debriefing protocol on knowledge, problem-solving process, critical thinking disposition, and clinical judgment in nursing students. A randomized controlled trial was performed. Fifty-six junior nursing students were assigned to the TLT (n = 26) and the control (n = 30) groups in South Korea. Debriefing protocols based on Mezirow's TLT for the experimental group and gather-analyze-summarize-based debriefing for the control group were used for four weeks. Scores of the TLT group were significantly higher than those of the control group in the problem-solving process, critical thinking disposition, and clinical judgment of reflection. We identified the main effects of group, time, and time-by-group interaction for clinical judgment (noticing, interpreting, and responding), except for knowledge between the two groups. The TLT debriefing approach in simulation can be tailored to improve problem-solving, critical thinking, and clinical judgment outcomes, which are vital to nursing education related to the provision of care to patients.
