Abstract
BACKGROUND: Although exposure therapy is a proven treatment for post-traumatic stress disorder (PTSD), empirical research is difficult due to ethical issues. Recently, virtual reality-based content that can provide space and time similar to reality for exposure therapy techniques is increasing. AIM: To examine exposure therapy using driving simulations in patients with PTSD due to traffic accidents with PTSD symptoms. METHODS: The intervention was provided to two individuals who experienced PTSD symptoms after a traffic accident using a driving simulator. Among the single-subject experimental designs, the ABA (baseline-intervention-baseline) design was used, and the PTSD checklist and brain wave frequency were used to measure the results. RESULTS: In all participants, the standard category departure time of the electroencephalogram decreased from baseline, and PTSD symptoms decreased after the intervention. CONCLUSION: These results suggest the potential use of a driving simulator as an exposure treatment tool for PTSD.
