Virtual reality exposure therapy (VRET) is an intervention used to treat alcohol and nicotine dependence that delivers cue exposure therapy using a virtual reality environment; however, little is known about the effects of these interventions.
Method:
We used systematic review methods to examine the effects of VRET on alcohol or nicotine dependence, craving, and substance use with persons with current nicotine or alcohol dependence. We conducted a comprehensive search to retrieve published and unpublished intervention studies in 18 databases and other gray literature sources. Studies were screened, and data were extracted by two independent reviewers.
Results:
Five studies including 212 participants were included. Effects were found for alcohol and nicotine dependence and craving; however, significant methodological issues and high risk of bias were present across studies.
Conclusion:
Evidence of effects of VRET is sparse, and methodological flaws and gaps in reporting were identified. Implications for practice and research are discussed.
