简要总结
The identification of mechanisms that underlie how people reduce or eliminate alcohol use is a critical public health issue. Understanding these mechanisms can inform how to effectively intervene with problem drinkers. Thus far it has been a challenge for the alcohol research field to find consistent empirical evidence in support of candidate mechanisms of behavior change. Scientific advancement in this area may be aided by longitudinal transdisciplinary research on the interplay between behavioral intervention, cognition, and brain activity to understand underlying processes of behavior change among heavy drinkers. This study employed a randomized 2-arm repeated measures design with a sample of non-treatment seeking adult heavy drinkers to examine changes in perceived reward value and risks of alcohol use as a mechanism of alcohol behavior change after a brief behavioral intervention. Participants were randomized to either a 1-session behavioral intervention or to an attention-matched control condition and immediately after completed an fMRI scan. The focus of this project is to examine if group differences in perceived alcohol reward value after the intervention mediates an intervention effect on reducing alcohol use in the 1 month following the intervention.
