Alcohol cues increase behavioral economic demand and craving for alcohol in nontreatment‐seeking and treatment‐seeking heavy drinkers

Abstract

AbstractBackgroundBehavioral economic research has revealed significant increases in alcohol demand following exposure to alcohol‐related cues. Prior research has focused exclusively on nontreatment‐seeking heavy drinkers, included only male participants, or used heterogeneous methods. The current studies sought to replicate and extend existing findings in treatment‐seeking and nontreatment‐seeking heavy drinkers while also examining sex effects and moderation by alcohol use disorder (AUD) severity.MethodsStudy 1 included 117 nontreatment‐seeking heavy drinkers (51.5% women; M age 34.69; 56.4% AUD+), and Study 2 included 89 treatment‐seeking heavy drinkers with AUD (40.4% women; M age = 41.35). In both studies, alcohol demand was measured using a hypothetical alcohol purchase task (APT), and subjective alcohol craving was measured using visual analog scales. Measures were collected following exposure to neutral (water) cues in a standard room and alcohol cues in a bar lab.ResultsAlcohol demand (intensity, Omax, breakpoint, and elasticity) and craving were significantly increased following alcohol cues compared to neutral cues (ps < 0.005) with effect sizes ranging from small to large (ηp2 = 0.074–0.480). Participants with AUD (Study 1) or with higher AUD severity (Study 2) reported higher craving and higher demand for most indices (i.e., main effects; ps < 0.032, ηp2 = 0.043–0.239). A larger alcohol cue increase in Omax was found for AUD+ participants in Study 1 compared to non‐AUD participants (p = 0.028, ηp2 = 0.041) but not for any other indices in Study 1 or Study 2. There were no significant sex effects.ConclusionsThese findings replicate and extend prior research by offering additional insight into alcohol cue effects on the reinforcing value of alcohol and subjective motivation to drink. The results also suggest that sex and AUD severity do not meaningfully impact cue effects across most indices of demand.
