Alcohol Use Disorder (AUD) is a chronic condition that affects behavior, decision-making, and the ability to adapt to changing situations. While many studies have examined AUD from medical and social perspectives, less is known about how individual psychological traits influence the way people with AUD respond to uncertainty and adapt their behavior.
This study aims to better understand how personal characteristics such as anxiety, self-esteem, sensitivity to reward and punishment, perfectionism, and cognitive abilities may influence adaptation processes in individuals with AUD.
Participants receiving usual care at Paul Brousse Hospital will be invited to take part in a single experimental session lasting about 45 minutes. During this session, they will complete:
The learning task is designed to evaluate how participants adjust their behavior when the rules of the task change unexpectedly. Researchers will measure how performance changes in response to uncertainty and examine how these changes relate to individual psychological characteristics.
This research does not modify participants' medical care and involves no medication or invasive procedures.
By improving understanding of the cognitive and behavioral mechanisms involved in Alcohol Use Disorder, the study may help advance scientific knowledge about how individuals adapt to uncertainty and inform future research in addiction and mental health.
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.

Exclusion Criteria:
Uncertainty Cost Index During Behavioral Adaptation Task
Uncertainty cost index. Exploration-exploitation behaviors are inferred from the percentage of correct responses obtained during the CHEAT phase of the computerized task. For each participant, the difference in accuracy rate between the end of the learning phase and the beginning of the CHEAT phase is calculated. This difference (Δ) defines the uncertainty cost index and reflects exploratory behavioral responses to the introduction of misleading feedback.
Time frame: At the end of the learning phase and at the beginning of the uncertainty phase during the single study session (approximately 45 minutes)
Correlation Between Uncertainty Cost Index and Psychometric Trait Scores
Correlation coefficient between the uncertainty cost index and standardized psychometric test scores assessing personality traits and cognitive characteristics.
Time frame: During the single study session (approximately 45 minutes)
