ABSTRACT

Background/Objectives: This research intended to systematically identify how a VR video aimed at improving recipients’ health affects their health efficacy through structural equation modeling. 

Method/Statistical analysis: The experiment was conducted with four participants simultaneously for 30 minutes at a time at the Virtual Reality and Health Research Center over approximately two weeks from May 1 to May 17, 2017. Data were collected using a self-report questionnaire. The final data used for the analysis were from 150 students consisting of 75 male and 75 female students. 

Findings: Confirmatory factor analysis was performed to evaluate the construct validity of the scale using AMOS 22. The data analyzed included participants’ responses on 22 items designed to measure five latents(social presence, arousal, message attention, message acceptance, health efficacy) constructs. Hypothesis 1 is whether social presence of VR Video is positively associated with arousal. SEM analysis indicated that social presence for VR Video is significantly associated with arousal, supporting the hypothesis. Hypothesis 2, 3 is whether arousal of VR Video is positively associated with message attention and acceptance. SEM analysis indicated that arousal for VR Video is significantly associated with message attention and acceptance, supporting the hypothesis. Hypothesis 4, 5 is whether message attention and acceptance is positively associated with health efficacy. SEM analysis indicated that message attention and acceptance for VR Video is significantly associated with health efficacy, supporting the hypothesis. 

Improvements/Applications: This research is believed to contribute to the convergence and expansion of new theories as it approached the subject matter based on VR user experience, and demonstrated important contributors to health efficacy.
