背景资料：行为决策，如爱荷华州赌博任务（IGT）的测量被发现在物质依赖和其他类型的去抑制精神病理学的个人减少。然而，很少有人知道大量饮酒和决策技能之间的关系在年轻人。因此，本研究调查了酗酒是否与不利的决策有关，如IGT所测量的。我们还研究了决策和impulsivity.Methods之间的关系：潜在的类增长分析被用来将大学生分为4组（每组n=50，50%男性），根据他们的狂饮轨迹超过2年的时间段（大学前通过第二年的大学）。参与者是200名大学生，分为4个亚组：（1）低狂欢饮酒者，（2）稳定的中度狂欢饮酒者，（3）增加狂欢饮酒者，（4）稳定的高狂欢饮酒者。一个措施的决策，IGT，冲动问卷调查，和多个指标的重度酒精useed.Results：稳定的高暴饮暴食组的IGT比低暴饮暴食组的有利选择。冲动性与决策绩效无关。决策性能并没有不同的性别，但甲板的喜好和决策时间模式不同，女性喜欢低频率，高金额的惩罚在更大程度上比manifest.Conclusions：虽然不利的决策与酗酒模式在成年初，这种关系是独立的冲动。此外，这种关联似乎可归因于那些在早期就大量饮酒的人，而不是一般的饮酒年龄。
Background: Behavioral decision making, as measured by the Iowa Gambling Task (IGT) is found to be diminished in individuals with substance dependence and other types of disinhibitory psychopathology. However, little is known regarding the relation between heavy alcohol use and decision-making skills in young adults. This study therefore investigated whether binge drinking is related to disadvantageous decision making, as measured by the IGT. We also examined the relation between decision making and impulsivity.Methods: Latent class growth analysis was used to classify college students into 4 groups (each group n=50, 50% male), based on their binge drinking trajectories over a 2-year time period (precollege through second year of college). Participants were 200 college students, divided in 4 subgroups: (1) low binge drinkers, (2) stable moderate binge drinkers, (3) increasing binge drinkers, and (4) stable high binge drinkers. A measure of decision making, the IGT, impulsivity questionnaires, and multiple indicators of heavy alcohol use were included.Results: The stable high binge-drinking group made less advantageous choices on the IGT than the low binge-drinking group. Impulsivity was not related to decision-making performance. Decision-making performance did not differ by gender, but deck preferences and decision time patterns did differ; women preferred low frequency, high amount punishments to a greater extent than men.Conclusions: Although disadvantageous decision making is related to binge-drinking patterns in emerging adulthood, this relation is independent of impulsivity. Additionally, the association appears attributable to those who engage in heavy (binge) drinking at an early age, but not to age of onset of drinking in general.
