Influence of Individual Traits on Adaptation Processes in Individuals With Alcohol Use Disorder

Alcohol Use Disorder (AUD) is associated with difficulties in decision-making and behavioral adaptation, particularly in situations involving uncertainty. Individual psychological traits may influence how people with AUD adjust their behavior when facing changing environments, but this relationship remains insufficiently understood. This monocentric, non-interventional study aims to explore how individual traits influence adaptive processes in adults diagnosed with Alcohol Use Disorder. Participants receiving usual care at Paul Brousse Hospital will attend a single experimental session lasting approximately 45 minutes. During this session, they will perform a computerized learning task designed to evaluate behavioral adaptation when task rules change unexpectedly. They will also complete standardized questionnaires assessing personality traits and cognitive functioning. Behavioral performance during the task will be analyzed to measure adaptation to uncertainty and examined in relation to individual psychological characteristics. The study does not involve medication, medical devices, or any modification of clinical care.
