Believing Is Seeing: A Proof-of-Concept Semiexperimental Study on Using Mobile Virtual Reality to Boost the Effects...

Cognitive Bias Modification of Interpretations (CBM-I) is a computerized intervention designed to change negatively biased interpretations of ambiguous information, which underlie and reinforce anxiety. The repetitive and monotonous features of CBM-I can negatively impact training adherence and learning processes.

This proof-of-concept study aimed to examine whether performing a CBM-I training using mobile virtual reality technology (virtual reality Cognitive Bias Modification of Interpretations [VR-CBM-I]) improves training experience and effectiveness.

A total of 42 students high in trait anxiety completed 1 session of either VR-CBM-I or standard CBM-I training for performance anxiety. Participants' feelings of immersion and presence, emotional reactivity to a stressor, and changes in interpretation bias and state anxiety, were assessed.

The VR-CBM-I resulted in greater feelings of presence (P<.001, d=1.47) and immersion (P<.001, η_p²=0.74) in the training scenarios and outperformed the standard training in effects on state anxiety (P<.001, η_p²=0.3) and emotional reactivity to a stressor (P=.03, η_p²=0.12). Both training varieties successfully increased the endorsement of positive interpretations (P<.001, d_{repeated measures} [d_rm]=0.79) and decreased negative ones. (P<.001, d_rm=0.72). In addition, changes in the emotional outcomes were correlated with greater feelings of immersion and presence.

This study provided first evidence that (1) the putative working principles underlying CBM-I trainings can be translated into a virtual environment and (2) virtual reality holds promise as a tool to boost the effects of CMB-I training for highly anxious individuals while increasing users' experience with the training application.
