Abstract

Background: Previous research suggests that high levels of anxiety sensitivity (AS; fear of anxiety symptoms) may constitute a risk factor for alcohol abuse. The present study evaluated the hypothesis that high AS levels mayincrease risk for alcohol abuse by promoting a heightened sober reactivityto theoretically relevant stressors and heightened sensitivity to alcohol's emotional reactivity dampening effects, which would negatively reinforce drinking in this population. Methods: One hundred and two undergraduate participants (51 high AS, 51 low AS) with no history of panic disorder were assigned to either a placebo, low-dose alcohol, or high-dose alcohol beverage condition (17 high AS, 17 low AS per beverage condition). After beverage consumption and absorption, participants underwent a 3 min voluntary hyperventilation challenge. Results and Conclusions: High-AS/placebo participants displayed greater affective and cognitive reactivity to the challenge than low-AS/placebo participants, which indicated increased fear and negative thoughts (e.g., "losing control") during hyperventilation among sober high AS individuals. Dose-dependent alcohol dampening of affective and cognitive reactivity to hyperventilation was observed only among high-AS participants, which suggested that high-AS individuals may be particularly sensitive to alcohol-induced reductions in their degree of fear and negative thinking in response to the experience of physical arousal sensations. In contrast, dose-dependent alcoholdampening of self-reported somatic reactivity was observed among both high- and low-AS participants. We discuss implications of these results for understanding risk for alcohol abuse in high-AS individuals, as well as directions for future research.
