背景：与异性恋者相比，性少数群体（如女同性恋、男同性恋、双性恋）患酒精使用障碍（AUD）的风险增加。少数族裔压力模型假设AUD的差异部分源于特定于性少数群体的压力（例如异性恋）。然而，很少有研究探讨心理生理标记的少数民族压力反应和心理生理压力反应是如何与终身少数民族的压力和酒精使用的性少数。惊恐反应的情绪调节是一个在受控实验室条件下捕获心理生理应激反应的成熟范式。PurposeThis初步研究是第一个使用惊恐实验范式来研究性少数群体对污名的心理生理反应的研究。年龄18 ~ 27岁（M= 21.80，SD = 2.65）。我们比较了三种类型的刺激（耻辱，消极和中性）的酗酒性少数青年人的惊吓反应。虽然统计不足，我们还探讨了惊吓反应和自我报告的饮酒行为和终身少数stress.ResultsBoth耻辱和一般不愉快的刺激之间的关联产生更多的心理生理应激反应比中性刺激性少数。心理生理应激反应与过去一个月饮酒日报告的大量饮酒有关，但与频率无关。此外，终身暴露于少数民族的压力与迟钝的反应耻辱stimulation.ConclusionsThese研究结果提供了方法上的进步和重要的影响，少数民族的压力理论和酒精使用之间的性少数。
Background: Sexual minorities (e.g. lesbian, gay, bisexual) are at increased risk for alcohol use disorder (AUD) compared to heterosexuals. The minority stress model postulates that disparities in AUD stem, in part, from stress specific to sexual minorities (e.g. heterosexism). However, little research has examined psychophysiological markers of minority stress reactivity and how psychophysiological stress reactivity is associated with lifetime minority stress and alcohol use among sexual minorities. Emotion modulation of the startle response is a well-established paradigm for capturing psychophysiological stress reactivity under controlled laboratory conditions.PurposeThis preliminary study is the first to use the startle experimental paradigm to examine psychophysiological reactivity to stigma among sexual minorities.ProceduresSexual minority participants (N= 20; 55% female), aged 18 to 27 years (M= 21.80,SD= 2.65), were recruited from the community. We compared startle reactivity in response to three types of stimuli (stigma, negative, and neutral) among heavy drinking sexual minority young adults. Although statistically underpowered, we also explored the associations between startle reactivity and self-reported drinking behaviors and lifetime minority stress.ResultsBoth stigma and general unpleasant stimuli produced more psychophysiological stress reactivity than neutral stimuli among sexual minorities. Psychophysiological stress reactivity was correlated with greater quantity of drinks reported on drinking days in the past month, but not greater frequency. Additionally, lifetime exposure to minority stress was associated with a blunted reactivity to stigma stimuli.ConclusionsThese findings provide methodological advances and important implications for minority stress theory and alcohol use among sexual minorities.
