Purpose: This study was conducted to confirm the effects of self-directed practice using augmented reality simulation on nursing students' confidence in nursing skills, ability to apply them, and satisfaction with self-study. Method: This was a quasi-experimental study with a non-synchronized pretest/posttest nonequivalent control group design. The study participants were 58 second-grade nursing students (29 in the experimental group and 29 in the control group) from Y city. The questionnaire was used to evaluate the confidence in nursing skills (16 questions), performance ability (23 questions), and satisfaction with self-practice (17 questions). The experimental group intervention was an autonomous practice using augmented reality simulation, and the control intervention was an autonomous practice using video-based interventions. The collected data were analyzed by t-test, x2-test, and ANCOVA (Analysis of Covariance) using the SPSS 25.0 program. Results: The experimental group outperformed the control group in terms of nursing skill confidence (F=25.79, p<.001), nursing skill performance ability (F=67.10, p<.001), and self-study satisfaction (F=14.10, p=.001). Conclusion: Self-directed practice using augmented reality simulation was confirmed to be an effective method to increase confidence, ability and practice satisfaction in nursing skills.
