酒精提示反应性，可操作为对酒精相关刺激的经典条件反应，可以通过心率变异性 (HRV) 等生理功能的变化进行评估，心率变异性反映了情绪和认知过程的实时调节。尽管有充足的证据将饮酒史与提示反应性联系起来，但目前尚不清楚当前的提示反应性是否与一系列关于酒精影响的巩固信念（即预期）相结合，以及治疗是否有助于区分积极与消极预期与提示反应性的关系。本研究考察了两组新生成年人对酒精图片线索的反应性与饮酒预期之间的关系：一组患有酒精使用障碍的住院患者样本（n=28），另一组是大学生样本，此前因违反大学有关宿舍内饮酒的政策而被要求进行简短干预（n=43）。使用几个 HRV 指数和自我报告唤醒评级作为线索反应性测量进行序贯回归分析。结果表明，两组的线索反应性和负面酒精结果预期之间的关系不同。使用HRV指数评估的更大的提示反应性与住院患者样本中更多的负面预期相关，但在强制学生样本中与更少的负面预期相关，而主观唤醒则发现了相反的趋势。目前的研究结果强调了通过包括 HRV 等生理标志物在内的多维评估方式来表征线索反应性的重要性。
Alcohol cue reactivity, operationalized as a classically conditioned response to an alcohol related stimulus, can be assessed by changes in physiological functions such as heart rate variability (HRV), which reflect real time regulation of emotional and cognitive processes. Although ample evidence links drinking histories to cue reactivity, it is unclear whether in-the-moment cue reactivity becomes coupled to a set of consolidated beliefs about the effects of alcohol (i.e., expectancies) and whether treatment helps dissociate the relation of positive versus negative expectancies to cue reactivity. This study examined the relationship between reactivity to alcohol picture cues and alcohol expectancies in two groups of emerging adults: an inpatient sample with alcohol use disorders (n=28) and a college student sample who previously were mandated to a brief intervention for violating university policies about alcohol use in residence halls (n=43). Sequential regression analysis was conducted using several HRV indices and self-report arousal ratings as cue reactivity measures. Results indicated that the relationship between cue reactivity and negative alcohol outcome expectancies differed for the two groups. Greater cue reactivity, assessed using HRV indices, was associated with more negative expectancies in the inpatient sample but with less negative expectancies in the mandated student sample, while an opposite trend was found for subjective arousal. The present findings highlight the importance of characterizing cue reactivity through multi-dimensional assessment modalities that include physiological markers such as HRV.
