Virtual Reality in Theory-Based Intervention: Examining the Efficacy of a Theory-Based Virtual Reality Intervention to Promote Physical Activity

Physical activity is crucial for health, and increasing it would benefit many people. Theory-based interventions have shown promise in promoting physical activity but often require trained specialists. Virtual reality (VR) has been helpful in various health domains, yet limited research exists on its use for theory-based physical activity interventions. This study explores the potential of VR to promote physical activity through theory-based interventions. We designed and simulated two VR exercise options to address the perceived barriers to habitual physical activity. Study participants completed pre- and post-questionnaires, which were analysed to assess the impact on behavioural determinants like self-efficacy, subjective norms, and exercise intention. Statistical analysis showed that the VR intervention increased participants’ intention and confidence in engaging in physical activity. We also discuss the framework and factors for successful theory-based VR interventions.
