Effects of Alcohol on the Response to Hyperventilation of Participants High and Low in Anxiety Sensitivity
Bibliographic record
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 may increase risk for alcohol abuse by promoting a heightened sober reactivity to 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 alcohol dampening 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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
