Evaluation of a Virtual Reality-based Version of the Multiple Errands Test in Alcohol Use Disorder (EVIMETAL)
Evaluation of a Virtual Reality-based Version of the Multiple Errands Test for the Assessment of Executive Functions 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:
- evaluate if the performance in the virtual version of the test is related to the performance in the original test in patients with AUD.
- 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.

Detaljeret beskrivelse
The project aims to validate the virtual version of the Multiple Errands Test (V-MET) as a tool for assessing executive function in patients with alcohol use disorder (AUD), in comparison to the original test (MET), by:
- establishing the ecological validity of the V-MET: a high correlation between performance on the MET and performance on the V-MET (total number of errors) in patients with TUAL and executive dysfunction.
- establishing the sensitivity of the V-MET (to executive dysfunction): significant difference between V-MET performance in patients with an AUD and executive dysfunction versus (a) patients without executive dysfunction and (b) "healthy" volunteers

Intervention / Behandling |
|---|---|
|
Eksperimentel: AUD group with executive function deficit
Group of patients with alcohol use disorder and a deficit in executive functions as assessed by the Frontal Assessment Battery
|
The 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).
The 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) . |

Aktiv komparator: AUD group without executive function deficit
Group of patients with alcohol use disorder but without a deficit in executive functions as assessed by the Frontal Assessment Battery
