较高的酒精奖励值（RV）与较高的饮酒水平和酒精相关后果有关，有证据表明，特定的饮酒动机可能调解大学生需求与问题酒精使用之间的关系，使这些变量成为高RV和酒精问题风险的潜在重要指标。本研究在退伍军人的高风险样本中评估了这些关系。长期自由行动或伊拉克自由行动（OEF/OIF）的重度饮酒退伍军人（N = 68）完成了酒精需求（RV）的酒精购买任务（APT）测量，并对酒精消费、酒精相关问题和饮酒动机进行了标准评估。RV与整体酒精后果、人际酒精后果、社会责任后果和冲动控制后果相关。中介分析表明，社会动机、应对焦虑动机、应对抑郁动机和增强动机对RV与多个问题分量表的关系具有显著的中介作用。这表明，对酒精评价高的人可能在社交、情绪改善和应对情况下有更大的饮酒动机，从而导致与酒精相关的后果增加。需求和饮酒动机应作为干预服务需求的潜在指标和退伍军人的治疗目标加以审查。
Elevated alcohol reward value (RV) has been linked to higher levels of drinking and alcohol-related consequences, and there is evidence that specific drinking motives may mediate the relationship between demand and problematic alcohol use in college students, making these variables potentially important indicators of risk for high RV and alcohol problems. The present study evaluated these relationships in a high-risk sample of military veterans. Heavy-drinking (N = 68) veterans of Operations Enduring Freedom or Iraqi Freedom (OEF/OIF) completed the alcohol purchase task (APT) measure of alcohol demand (RV), and standard assessments of alcohol consumption, alcohol-related problems, and drinking motives. RV was associated with overall alcohol consequences, interpersonal alcohol consequences, social responsibility consequences and impulse control consequences. Mediation analyses indicated significant mediation of the relationships between RV and a number of problem subscales by social motives, coping-anxiety motives, coping-depression motives and enhancement motives. This suggests that individuals who have a high valuation of alcohol may have increased motivation to drink in social, mood-enhancement, and coping situations, resulting in increased alcohol-related consequences. Demand and drinking motives should be examined as potential indicators of need for intervention services and as treatment targets in veterans.
