Neural and Mobile Assessment OF Behavior Change Among Problem Drinkers

New York State Psychiatric Institute164 enrolled

Overview

This study will examine the neural mechanisms underlying both spontaneous behavior change and behavior change in response to a brief intervention among problem drinkers.

Although problem drinkers (PD) are a less severe, highly prevalent sub-type of alcohol use disorder (AUD) who are more likely to undergo reductions in alcohol use, compared to more severe AUD, the underlying mechanisms that maintain PD, as well as the mechanisms that underlie both spontaneous and treatment- related behavior change in this population, are not well understood. This proposal takes a lab to life approach by combining functional neuroimaging (fMRI), ecological momentary assessment (EMA), and brief interventions (BI) in non-treatment seeking PD to test whether heightened incentive salience (reactivity) to alcohol cues and impaired ability to regulate cue-induce craving are the mechanisms that characterize PD, and play a role in behavior change vs. persistence of behavior. Identifying these mechanisms is critical for testing and understanding treatments and uncovering who is most likely to respond to interventions.
