Craving for alcohol: Findings from the clinic and the laboratory

Abstract

This paper presents a review of the current status of empirical research in the area of alcohol craving. After an introduction on the origins of the construct of craving, we first present clinical studies that have examined craving as a hallmark symptom of alcohol dependence and demonstrated its sensitivity as an outcome measure in assessing change in pharmacotherapy trials of alcohol dependence. There is also discussion regarding new multifactorial self-report instruments of alcohol craving with good reliability and predictive validity, that may be sensitive to detecting alcohol craving and assessing change in craving as it relates to relapse during treatment. Next, we examine the experimental paradigms that have been used to induce alcohol craving in the laboratory. Further, the methodological issues affecting laboratory-based paradigms are presented, while also elucidating the potential use of effective laboratory-based craving induction paradigms, both in clinical studies as well as in laboratory studies that examine the brain mechanisms associated with the concept of craving. Finally, directions for future research on craving in the laboratory and the clinic are presented in the context of developing more effective treatments for different phases of recovery from alcohol dependence.
