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.

Parallel
Multiple Errand Test (MET)
BehavioralThe test takes place in a real supermarket. Participants must complete a list of tasks (e.g., purchasing certain items, collecting some information) while adhering to rules (e.g., not visiting the same place twice, etc).
Virtual MET
BehavioralThe test takes place in a virtual supermarket, developed on the C2Neuro app by C2CARE®. Participants must complete a similar list of tasks to the MET (e.g., purchasing certain items, collecting some information) and adhere to similar to rules (e.g., not visiting the same place twice, etc) .
Total number of errors on the test
Total number of errors on the MET and the V-MET. Errors include: * Inefficiencies (a more effective action could have been made) * Rule breaks: a specific rule is broken * Interpretation failure (the task is misunderstood or misinterpreted) * Task failure: not carried out or not completely completed
Inefficiencies on the test
Inefficiencies on the MET/V-MET : a more effective action could have been made Can be infinite
Rule breaks on the test
Rule breaks on the MET / V-MET : a specific rule is broken
Interpretation failures on the test
Interpretation failures on the MET/V-MET : the task is misunderstood or misinterpreted
Task failures on the test
Task failures on the MET / V-MET : task not carried out or not completely completed
