A Randomized, Head-to-Head Study of Virtual Reality Exposure Therapy for Posttraumatic Stress Disorder

Area of Science:

• Psychiatry
• Psychology
• Military Medicine

Background:

• Virtual reality exposure therapy (VRET) shows promise for treating combat-related PTSD in active duty service members.
• Randomized controlled trials support VRET, but its comparative effectiveness against traditional methods needs further investigation.

Purpose of the Study:

• To compare the effectiveness of VRET versus control exposure therapy (CET) for combat-related PTSD.
• To determine if virtual reality technology offers additional benefits beyond standard exposure therapy.

Main Methods:

• A comparative effectiveness study randomly assigned service members with combat-related PTSD to nine weeks of VRET or CET.
• Clinician-Administered PTSD Scale (CAPS) assessed PTSD symptom improvement one week and three months post-treatment.
• Assessors were blinded to treatment conditions, but therapists were not.

Main Results:

• Both VRET and CET led to significant PTSD symptom improvement.
• No statistically significant differences in outcomes were observed between VRET and CET groups.
• Dropout rates were higher in the VRET group compared to the CET group.

Conclusions:

• Exposure therapy is effective for treating combat-related PTSD in service members.
• The inclusion of virtual reality in exposure therapy did not demonstrate additional benefits over traditional CET.
• Further research may explore factors contributing to higher dropout rates in VRET.
