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. (PsycINFO Database Record
酒精奖赏值（RV）升高与更高水平的饮酒及酒精相关后果有关，并且有证据表明特定的饮酒动机可能介导大学生对酒精的需求与酒精使用问题之间的关系，这使得这些变量可能成为高奖赏值和酒精问题风险的重要指标。本研究在高危退伍军人样本中评估了这些关系。参与过持久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）完成了酒精购买任务（APT）以测量酒精需求（奖赏值），并对酒精消费、酒精相关问题及饮酒动机进行了标准评估。奖赏值与总体酒精后果、人际酒精后果、社会责任后果及冲动控制后果相关。中介分析表明，社交动机、应对焦虑动机、应对抑郁动机及增强动机对奖赏值与多个问题分量表之间的关系起到了显著的中介作用。这表明，对酒精评价较高的个体在社交、情绪增强及应对情境中可能有更强的饮酒动机，从而导致更多与酒精相关的后果。应将对酒精的需求和饮酒动机作为退伍军人干预服务需求的潜在指标及治疗靶点进行研究。（PsycINFO数据库记录）
