Sensory and Physical Reactions to Beverage Cues
Sensory and Physiological Responses to Beverage Stimuli: A Randomized Crossover Study
University of Texas Southwestern Medical Center
20 participants

INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to evaluate changes in craving and sensory responses to different beverage cues in adults (aged 21-70) with current mild or greater alcohol use disorder (AUD). The main questions it aims to answer are: * Does exposure to different beverage cues elicit distinct changes in subjective craving? * How do beverage liking, peak craving, and the return of craving to baseline compare across different test-beverage conditions? Researchers will compare Session A (Test Beverage Condition A) to Session B (Test Beverage Condition B) in a randomized crossover design to see if sensory and expectancy effects influence craving responses without consumption. Participants will: * Complete two separate 3-minute cue reactivity trials per session (a baseline water cue, followed by a test-beverage cue) while listening to guided audio instructions and holding/smelling the beverage without drinking it. * Rate their craving and beverage liking using visual analog scales (VAS) immediately after each trial. * Provide breathalyzer readings (BrAC), vital signs, and safety/medication checks at both study visits. * Complete diagnostic and drinking history assessments (such as the SCID-5, TLFB, and ACQ-SF-R).
