What is the efficacy of virtual reality exposure therapy in reducing PTSD symptoms?
The aim of this systematic review is to explore the effectiveness of a new novel PTSD inter-vention (virtual reality exposure therapy, VRET) on PTSD symptoms. In this review PTSD symptoms were looked through the scope of the clinician administered PTSD scale (CAPS). Secondary outcome measures that were analyzed were physiological response, depression symptoms and drop-out rates.
This systematic review gathered articles from multiple databases with the main inclusion crite-ria being, that the study had to report relevant information on the effectiveness of VRET on a sample of clinically significant PTSD participants according to the DSM-IV or DSM-5 classi-fication of PTSD. The assessment of PTSD symptoms had to be done using the clinician ad-ministered PTSD scale. The final selection yielded 14 studies.
This review found that VRET reduces CAPS scores significantly and that in follow-up meas-urements these results are maintained. However, when VRET was compared to other forms of PTSD treatment VRET did not consistently outperform these interventions. In terms of sec-ondary measures, VRET reduced depression symptoms significantly in posttreatment and fol-low-up measures. Pooled drop-out rate of participants in VRET interventions were markedly higher when compared to relevant literature around PTSD treatment drop-out rates.
In conclusion, VRET in the light of this review looks to be an efficacious form of PTSD treatment in terms of outcome measures such as PTSD symptoms but also secondary measures such as comorbid depression symptoms. However, this claim is hindered by major limitations in population validity and increased drop-out rates when compared to other efficacious treat-ment forms of PTSD. These limitations have a limiting effect on the generalizability of VRET as an PTSD intervention.
