Résumé :

Cet essai a enquêté sur l’efficacité d’une intervention de l’exposition à la réalité virtuelle autonome comprenant l’interaction verbale avec les humains virtuels pour cibler les peurs sociales hétérogènes chez les participants souffrant de trouble d’anxiété sociale. Pour les thérapies par exposition à la réalité virtuelle, l’effet du stress perçu était significatif. Les TERV contenant une interaction verbale sans composantes cognitives, peuvent réduire efficacement les plaintes de trouble d’anxiété sociale généralisée. Des améliorations technologiques et psychologiques futures et des interactions sociales virtuelles pourraient encore améliorer l’efficacité des TERV pour le trouble d’anxiété sociale.

Abstract :

This randomized controlled trial investigated the efficacy of a stand-alone virtual reality exposure intervention comprising verbal interaction with virtual humans to target heterogeneous social fears in participants with social anxiety disorder. Sixty participants (Mage = 36.9 years; 63.3% women) diagnosed with social anxiety disorder were randomly assigned to individual virtual reality exposure therapy (VRET), individual in vivo exposure therapy (iVET), or waiting-list. Multilevel regression analyses revealed that both treatment groups improved from pre-to postassessment on social anxiety symptoms, speech duration, perceived stress, and avoidant personality disorder related beliefs when compared to the waiting-list. Participants receiving iVET, but not VRET, improved on fear of negative evaluation, speech performance, general anxiety, depression, and quality of life relative to those on waiting-list. The iVET condition was further superior to the VRET condition regarding decreases in social anxiety symptoms at post- and follow-up assessments, and avoidant personality disorder related beliefs at follow-up. At follow-up, all improvements were significant for iVET. For VRET, only the effect for perceived stress was significant. VRET containing extensive verbal interaction without any cognitive components can effectively reduce complaints of generalized social anxiety disorder. Future technological and psychological improvements of virtual social interactions might further enhance the efficacy of VRET for social anxiety disorder.
