Acute negative mood powerfully motivates alcohol-seeking behavior, but it remains unclear whether sensitivity to this effect is greater in drinkers who report depression symptoms, drinking to cope, and subjective reactivity. To examine these questions, 128 young adult alcohol drinkers (ages 18-25) completed questionnaires of alcohol use disorder symptoms, depression symptoms, and drinking to cope with negative affect. Baseline alcohol choice was measured by preference to enlarge alcohol versus food thumbnail images in two-alternative forced-choice trials. Negative mood was then induced by depressive statements and music, before alcohol choice was tested. Subjective reactivity was indexed by increased sadness pre- to post-mood induction. Baseline alcohol choice correlated with alcohol dependence symptoms (p = .001), and drinking coping motives (ps ≤ .01). Mood induction increased alcohol choice and subjective sadness overall (ps < .001). The mood-induced increase in alcohol choice was associated with depression symptoms (p = .007), drinking to cope (ps ≤ .03), and subjective reactivity (p = .007). The relationship between mood-induced alcohol choice and drinking to cope remained significant after covarying for other drinking motives. Furthermore, the three predictors (depression, drinking to cope, and subjective reactivity) accounted for unique variance in mood-induced alcohol choice (ps ≥ .03), and collectively accounted for 18% of the variance (p < .001). These findings validate the pictorial alcohol choice task as sensitive to the relative value of alcohol and acute negative mood. The findings also accord with the core prediction of negative reinforcement theory that sensitivity to the motivational impact of negative mood on alcohol-seeking behavior may be an important mechanism that links depression and alcohol dependence.

急性负面情绪会强烈激发寻求酒精的行为,但对于报告有抑郁症状、为应对负面情绪而饮酒以及主观反应性的饮酒者而言,对这种影响的敏感性是否更高仍不清楚。为了研究这些问题,128名年轻成年饮酒者(年龄在18至25岁之间)完成了关于酒精使用障碍症状、抑郁症状以及为应对负面情绪而饮酒的问卷调查。在两项选择强迫试验中,通过对酒精与食物缩略图图像放大的偏好来测量基线酒精选择。然后通过抑郁陈述和音乐诱导负面情绪,之后再测试酒精选择。情绪诱导前后悲伤感增加作为主观反应性指标。基线酒精选择与酒精依赖症状相关(p = 0.001),以及与饮酒应对动机相关(p值≤0.01)。情绪诱导总体上增加了酒精选择和主观悲伤感(p值<0.001)。情绪诱导导致的酒精选择增加与抑郁症状相关(p = 0.007)、与为应对负面情绪而饮酒相关(p值≤0.03)以及与主观反应性相关(p = 0.007)。在对其他饮酒动机进行协变量调整后,情绪诱导的酒精选择与为应对负面情绪而饮酒之间的关系仍然显著。此外,这三个预测因素(抑郁、为应对负面情绪而饮酒以及主观反应性)在情绪诱导的酒精选择中占独特方差(p值≥0.03),并且共同占方差的18%(p < 0.001)。这些发现验证了图像化酒精选择任务对酒精的相对价值和急性负面情绪敏感。这些发现也符合负强化理论的核心预测,即对负面情绪对寻求酒精行为的动机影响的敏感性可能是连接抑郁和酒精依赖的重要机制。(《心理学文摘数据库记录》
