Clinical Usefulness of the Iowa Gambling Task in Severe Alcohol Use Disorders: Link with Relapse and Cognitive-Physiological Deficits.

SAUD is not related to a global IGT deficit, as suggested earlier, but rather to a specific impairment for decision making under risk. This deficit is not associated with other disease-related variables and has no relapse prediction power. These results question the clinical usefulness of the IGT as a tool identifying key treatment levers and guiding (neuro)psychological rehabilitation.
