目的：探讨压力对重度社交饮酒者饮酒渴求和对酒精相关线索的注意偏向的影响。方法：四十四个重度社交饮酒者暴露于实验室压力源任务或控制操作之前完成的问卷测量酒精渴望和视觉探测任务，测量酒精相关线索的注意力偏差。参与者被细分为高水平和低水平的应对饮酒的动机。结果：与对照组相比，实验室应激任务使受试者的酒精渴求增加（P < 0.01）。实验室压力源任务也对酒精相关线索产生了显著的注意偏向，但仅在高水平应对动机的被试中存在（P < 0.05）。结论：研究结果与当代物质滥用的负强化模型以及物质相关线索的主观渴望和注意力偏差模型基本一致。
Aims: To investigate the effects of stress on alcohol craving and attentional bias for alcohol-related cues in a group of heavy social drinkers. Method: Forty-four heavy social drinkers were exposed to either a laboratory stressor task or a control manipulation before completing a questionnaire measure of alcohol craving and a visual probe task which measured attentional bias for alcohol-related cues. Participants were subdivided into those with high and low levels of coping motives for drinking. Results: Compared to a control manipulation, the laboratory stressor task produced increases in alcohol craving (P < 0.01). The laboratory stressor task also produced a significant attentional bias for alcohol-related cues, but only among participants who had high levels of coping motives (P < 0.05). Conclusions: Findings are broadly consistent with contemporary negative reinforcement models of substance abuse, and with models of subjective craving and attentional biases for substance-related cues.
