Stress and anxiety are widely believed to contribute to drinking. Alcohol is thought to reduce tension caused by stress (the "flight or fight" response) as well as alleviate the unpleasant symptoms of anxiety (anticipation of the unpredictable, impending threats). Prior research, however, has yielded inconsistent findings as to the unique relations between stress and anxiety, on the one hand, and alcohol consumption and alcohol use disorders, on the other hand. This study was designed to examine how differences in self-reported levels of anxiety, anxiety sensitivity, and perceived stress impact the frequency and intensity of drinking, alcohol craving during early withdrawal, and alcohol craving and stress reactivity.
