A Randomized Controlled Efficacy Trial of a Telemedicine-based Virtual Reality Clinic for the Treatment of Phobias
23 avril 2026 mis à jour par: University of South Florida
Doxy.me VR vs. Telemental Health-Based Exposure Therapy: Phase II
The goal of this clinical trial is to learn if a telemedicine-based virtual reality clinic (Doxy.me VR) works to treat dog, spider, and snake phobias in adults. The main questions it aims to answer are:
Does Doxy.me VR decrease the severity of phobias better than traditional telemedicine-based treatment? Does this work because it feels more realistic than telemedicine alone?
