在不熟悉的社交环境中经常饮酒与问题饮酒有关。大量的间接证据表明，酒精的有益情绪效应--无论是消极情绪的缓解还是积极情绪的增强--在不熟悉的社会环境和熟悉的社会环境中饮用时都会被放大。但实证研究从未直接研究过情境熟悉度和酒精奖励之间的联系。在目前的研究中，我们动员了新的流动技术来研究社会熟悉度对日常饮酒环境中酒精奖励的影响，同时还研究了在这些领域中观察到的酒精奖励如何与实验室中观察到的奖励相对应。重度社交饮酒参与者（N=48，50%男性）进行了为期一周的密集动态评估。参与者戴着透皮酒精传感器，同时报告他们的情绪，并根据随机提示拍摄他们的社交环境照片。参与者还参加了两个实验室饮料管理会议，在此期间，他们的情绪反应进行了评估和经皮传感器进行校准，以估计BrAC（eBrAC）。结果表明，社交熟悉度和酒精发作在日常饮酒环境中的显着相互作用，酒精在更大程度上提高情绪在相对陌生与熟悉的社交环境。研究结果还表明，在相对不熟悉的社交环境中饮酒与更高的eBrAC有关。最后，研究结果表明，实验室内外酒精对情绪的影响是一致的。这项研究提出了一种新的方法来检查酒精奖励，并指出社会熟悉度作为一个有前途的方向，寻求解释问题饮酒的研究。
Regular alcohol consumption in unfamiliar social settings has been linked to problematic drinking. A large body of indirect evidence has accumulated to suggest that alcohol’s rewarding emotional effects—both negative-mood relieving and positive-mood enhancing—will be magnified when alcohol is consumed within unfamiliar vs. familiar social contexts. But empirical research has never directly examined links between contextual familiarity and alcohol reward. In the current study, we mobilized novel ambulatory technology to examine the effect of social familiarity on alcohol reward in everyday drinking contexts while also examining how alcohol reward observed in these field contexts corresponds to reward observed in the laboratory. Heavy social drinking participants (N=48, 50% male) engaged in an intensive week of ambulatory assessment. Participants wore transdermal alcohol sensors while they reported on their mood and took photographs of their social contexts in response to random prompts. Participants also attended two laboratory beverage-administration sessions, during which their emotional responses were assessed and transdermal sensors were calibrated to estimate BrAC (eBrAC). Results indicated a significant interaction between social familiarity and alcohol episode in everyday drinking settings, with alcohol enhancing mood to a greater extent in relatively unfamiliar vs. familiar social contexts. Findings also indicated that drinking in relatively unfamiliar social settings was associated with higher eBrAC’s. Finally, results indicated a correspondence between some mood effects of alcohol experienced inside and outside the laboratory. This study presents a novel methodology for examining alcohol reward, and indicates social familiarity as a promising direction for research seeking to explain problematic drinking.
