This randomized controlled trial examined the effect of haptic glove-based virtual reality (VR) training on the aspiration skills and caregiving behaviors of intensive care nurses. A total of 60 nurses were randomly assigned to an experimental group receiving VR simulation supported by haptic gloves or a control group receiving standard mannequin-based training. Data were collected using the Nurse Information Form, Aspiration Skill Checklist, and Caregiving Behavior Scale. While VR training was effective in supporting aspiration skill development, no statistically significant differences were found between groups in total caregiving behavior scores or its subdimensions. These findings suggest that although VR and haptic technologies are valuable for enhancing technical skills, improvements in caregiving behaviors may require longer-term or repeated educational interventions.
