Background: Serious games (SGs) have been proposed as a type of technology-enhanced simulation that may provide nursing students with an opportunity to practice their clinical reasoning and decision-making skills in a realistic and safe environment. Materials and Methods: The aim of this study is to determine the effect of serious play on nursing students' self-confidence (SC) and anxiety in clinical decision making. The randomized controlled trial evaluated the efficacy of SGs for undergraduate nursing students using pre- and posttests. The study was conducted during nursing students' clinical practice and teaching. All undergraduate nursing students (n = 120) attending internal medicine nursing lesson were approached. Sixty students out of 120 answered the questionnaires at both baseline and follow-up (30 in the experimental group [EG] and 30 in the control group). The students answered the questionnaire after taking the first clinical practice, taking the endocrine course. In the 1 week, the EG played the game and both groups returned to clinical practice. Questionnaire data were collected after clinical application. Results: SC and two subdimensions, using the information in hand to determine the problem, and knowing and taking action, were improved in the intervention group and a significant interaction effect was found for changes over time between the two groups. Anxiety scores between groups were not statistically significant differences. Conclusions: Nursing professional educators can adopt SGs to improve cognitive and attention skills, strengthen judgment, require making time efficient, practice making safe decisions, and encourage the exploration of decision.
