About this trial
The goal of this observational study is to investigate longitudinal stress response profiles and adaptive versus non-adaptive stress responses in alcohol use disorder. The main questions the projects aims to answer are:
What are the neurobehavioral underpinnings of adaptive stress responses and resilience to repeated stress exposure with regards to:
* alcohol craving? * alcohol use? * their modulation by prior stress exposure, social interactions, coping strategies and individual health behavior?
Participants will:
* be exposed to an established experimental stress-induction protocol, the Trier Social Stress Test * be exposed to their favorite drink in a bar lab environment * be assessed using fMRI to determine their neural alcohol cue reactivity, response inhibition, and emotion processing * conduct an ambulatory phase to assess stressors, alcohol craving, substance use and details on social interactions, health behavior and coping strategies using ecological momentary assessment tools.
