Virtual reality for public health: a study on a VR intervention to enhance occupational injury prevention

Abstract

Background: Agriculture is one of the most hazardous occupations in the USA. Especially, tractor rollover incidents are the leading cause of farming-related injuries or deaths. This study examines the effect of a VR intervention (Virtual Reality Intervention for Safety Education; VRISE) on behavioral intentions for occupational safety and identifies a psychological mechanism that shows how the immersive technology works.

Methods: VRISE was developed by a multidisciplinary team of agricultural educators, computer scientists and communication specialists. It was designed to provide a virtual environment where users practice tractor operation and try to avoid several rollover hazards. The participants (291 high school students) were recruited at the 2019 National Future Farmers Association Convention & Expo and randomly assigned to one of three conditions: two different types of control groups (Control1: No treatment group and Control2: 2D Screen group) and the treatment group.

Results: Findings show that, through the immersive VR experience, the VR intervention enhanced perceived threat of tractor-related accidents which in turn, led to improved behavioral intentions for tractor safety.

Conclusions: Findings shed light on the effectiveness of a VR intervention to improve public health outcomes, especially in occupational safety education, where unsafe practices often result in injury and fatality.
