Table 2 Comparison of the effect of the VR intervention and control condition.

From: A randomized trial testing the effectiveness of virtual reality as a tool for pro-environmental dietary change

Intentions post

2.16, 95% CI [1.62, 2.69]

  1. All variables are calculated as change scores from baseline to the second measurement, except for Intentions and Knowledge, which are presented as post-intervention scores. Beta coefficients report the impact of the VR intervention compared to the control condition when controlled for the pre-intervention scores.
