Evaluation of a Virtual Reality-based Version of the Multiple Errands Test in Alcohol Use Disorder

The goal of this study is to validate the virtual version of the Multiple Errands Test (V-MET) as a tool for assessing executive functions in patients with alcohol use disorder (AUD). More specifically, the project aims to: 1. evaluate if the performance in the virtual version of the test is related to the performance in the original test in patients with AUD. 2. establish whether the virtual version of the test is sensitive enough to detect patients with or without an executive function deficit. All participants will perform the original version (in a real-life supermarket) and the virtual version of the test (in a virtual reality environment). Performance in the two versions of the test will be compared. Participants will also complete a battery of neuropsychological tests and questionnaires.
