The Efficacy of Virtual Reality Exposure Therapy (VRET) for Post-Traumatic Stress Disorder (PTSD): A Meta-Analysis of Randomized Controlled Trials
Abstract
Virtual Reality Exposure Therapy (VRET) has emerged as a promising intervention for Post-Traumatic Stress Disorder (PTSD), offering immersive and controlled environments for exposure to traumatic memories. This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of VRET in reducing PTSD symptoms and improving overall functioning in individuals with PTSD. Through a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of VRET compared to control conditions (e.g., waitlist, traditional exposure therapy) in targeting symptoms of PTSD, including intrusive thoughts, avoidance behaviors, hyperarousal, and negative mood. Additionally, it examines potential moderators of treatment outcomes, such as the type of trauma, level of immersion, therapist involvement, and participant characteristics (e.g., age, gender), to better understand the factors influencing the effectiveness of VRET for PTSD.
