An Attentional bias modification task, through virtual reality and eye-tracking technologies, to enhance the treatment of anorexia nervosa

Mirror exposure therapies (METs) have been shown to be effective in reducing body image disturbances through the habituation process. Virtual reality (VR) combined with eye-tracking techniques can provide innovative solutions to some of METs' limitations reported with patients with anorexia ner...

This pilot study aimed to assess the preliminary efficacy of a new VR-based AB modification task (ABMT) among healthy women and the procedure's user experience.

Overall, the software received a 'C-rating' on a scale from 'A' (most usable) to 'F' (least usable).

Overall, the software received a 'C-rating' on a scale from 'A' (most usable) to 'F' (least usable). These results provide evidence of the opportunity to use a VR-based ABMT procedure to reduce AB and improve existing treatments for AN.
