This randomized controlled trial aims to evaluate the effectiveness of a virtual reality (VR) music-movement exergaming intervention for improving social connectedness and psychological well-being among young adults. Participants will be randomly assigned to one of three groups: (1) a VR social music-movement exergame group, (2) a VR solo exergame group without social interaction, and (3) a waitlist control group. The intervention integrates rhythmic movement, music-based interaction, and immersive VR environments to promote engagement and social connection. Primary outcomes include changes in depressive symptoms, anxiety, and social connectedness. Secondary outcomes include psychological need satisfaction and physical fitness indicators. Assessments will be conducted at baseline, post-intervention, and follow-up. The study will provide evidence on the potential benefits of immersive VR-based exergaming interventions for mental health and social well-being in young adults.
