Effects of Drink‐Stress Sequence and Gender on Alcohol Stress Response Dampening in High and Low Anxiety Sensitive Drinkers
Bibliographic record
Abstract
Background: This study tested the appraisal disruption hypothesis of alcohol stress response dampening (SRD) in male and female high or low anxiety sensitive (AS) undergraduates. The hypothesis predicts that alcohol SRD will be greater when drinking occurs before versus after stress exposure. High AS males' predominant social‐evaluative concerns further implied that alcohol SRD to a social stressor (i.e., a speech) would be relatively stronger in high AS males than in high AS females. Methods: Male and female (n=90/gender) high and low AS participants (≥70th; ≤30th percentile on Anxiety Sensitivity Index‐Revised) were matched on drinking habits and randomly assigned to 1 of 9 experimental cells. Drink type—alcohol (0.7 g/kg males; 0.63 g/kg females), placebo, soda—was fully crossed with stress condition—drink before stress (DBS), drink after stress (DAS), and no stress control (NSC). Stress was induced by telling participants they would be required to make a self‐revealing speech. Stress response dampening was assessed for state anxiety on the Spielberger scale and Stroop interference to threat‐related words. Subjective desire for alcohol was also assessed. Results: Relative to placebo, alcohol (peak blood alcohol concentration, 0.064%) reliably reduced state anxiety in high AS but not in low AS participants. Alcohol decreased STAI scores and Stroop interference to social threat words significantly more in the DBS than the DAS condition in high AS males; high AS females displayed the exact opposite pattern of effects. In contrast to other participants, high AS males also reported relatively strong desire scores under alcohol. Conclusions: Overall, the results do not support the appraisal disruption hypothesis as a general mechanism of alcohol SRD in undergraduate drinkers. The findings for high AS males do support the hypothesis, while the opposing profile for high AS females implies that the nature of the stressor (i.e., social challenge) may contribute to gender differences in alcohol SRD in high AS individuals.

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.
