Enhancing Therapist Training in the Delivery of Exposure Therapy for Individuals with Anxiety Disorders Using Virtual...

Area of Science:

• Mental Health
• Clinical Psychology
• Virtual Reality Applications

Background:

• Exposure therapy is underutilized for anxiety disorders due to provider apprehension.
• Therapist beliefs about exposure are a significant barrier to its routine implementation.
• Virtual reality (VR) offers a scalable solution for standardized experiential training.

Purpose of the Study:

• To assess the usability and impact of a VR-based exposure training program (SET-VR).
• To evaluate effects on therapist knowledge, self-efficacy, and attitudes toward exposure.
• To compare the efficacy of high-immersion (HMD) versus lower-immersion (desktop) VR formats.

Main Methods:

• Clinicians (n=41) with active caseloads participated in a feasibility randomized controlled trial.
• Participants received didactic training followed by randomized assignment to desktop or HMD VR exposure simulation.
• Therapist outcomes (knowledge, self-efficacy, beliefs) were measured at multiple time points.

Main Results:

• Both VR groups showed significant improvements in exposure knowledge, self-efficacy, and beliefs post-didactic training.
• Further significant gains in self-efficacy and beliefs were observed post-experiential VR training.
• No significant differences were found between HMD and desktop VR formats; both were rated highly for acceptability and usability.

Conclusions:

• VR training, guided by an "exposure to exposure" (E2E) framework, effectively improved therapist self-efficacy and beliefs about exposure.
• The findings support VR as a standardized method for experiential practice, addressing therapist-level barriers.
• Lower-immersion VR may be sufficient, suggesting scalable implementations could enhance access to evidence-based care.
