Background and objective: Acquired accurate clinical nursing skills are among the most important core nursing competencies for nursing students, as nursing students' inadequate skill capacities might endanger patients safety. Therefore, it is essential to develop teaching strategies to strengthen students' nursing skills. This study examined the effects of an immersive three-dimensional (3D) interactive video program on improving nursing students' nasogastric tube feeding skill competence. Design: A randomized controlled trial research design. Settings and participants: Forty-five nursing students from a university in northern Taiwan. Methods: The students were randomly assigned to an intervention group (n = 22) and a comparison group (n = 23). The intervention group received the immersive 3D interactive video program on nasogastric tube feeding, whereas the comparison group watched a regular demonstration video. The questionnaire was used to collect data before the intervention, immediately after the intervention, and one month after the intervention. Results: Nursing students' knowledge and confidence in nasogastric tube feeding were significantly improved after the intervention in both groups. Although there were no significant differences in students' knowledge, skill, and confidence between the two groups, participants' average satisfaction score with the immersive 3D interactive video program in the intervention group was significantly higher than in the comparison group that watched a regular video (t = 2.302, p = 0.026). Conclusions: The findings of this study showed that both immersive 3D interactive video program and regular demonstration video could improve nursing students' learning outcomes. The higher satisfaction score in the intervention group indicates that learning through immersive 3D interactive video is acceptable and satisfactory. This study provides useful information for nursing faculty members for designing and developing teaching methods for the acquisition of nursing skills. It can also serve as a reference for further studies relating to AR, VR, or immersive learning materials.
