摘要

Emerging adulthood is a critical developmental period for examining food- and eating-related behaviors as long-term weight-related behavioral patterns are established. Virtual really (VR) technology is a promising tool for basic and applied research on eating and food-related processes. Thus, the present study tested the validly and user perceptions of a highly immersive and realistic VR food buffet by: (1) comparing participants' food selections made in the VR buffet and a real-world (RW) food buffet cafeteria one-week apart, and (2) assessing participants' rated perceptions of their VR experience (0-100 scale). Participants comprised an ethnically diverse sample of emerging adults (N = 35, M-age = 20.49, SD = 2.17). Results revealed that participants' food selections in the VR and RW food buffets were significantly and positively correlated in Kcals, grams, carbohydrates, and protein (all p's < 0.05). Moreover, participants perceived that (a) the VR buffet was natural (M = 70.97, SD = 20.92), (b) their lunch selection in the VR buffet represented a lunch they would select on an average day (M = 84.11, SD = 15.92); and (c) their selection represented a lunch they would select if the same foods were available (M = 91.29, SD = 11.00). Our findings demonstrated the validly and acceptability of our highly immersive and realistic VR buffet for assessing food selection that is generalizable to RW food settings one-week apart without precisely matched foods. The findings of this study support the utility of VR as a validated tool for research on psychological and behavioral food-related processes and training interventions among emerging adults.
