Many studies have documented associations of substance use with aggression perpetration and aggression victimization; however, little is known about the co-occurrence of these problem behaviors within the same day in college students. The present study investigated whether substance use and aggression increase the likelihood of each other and whether attitudes justifying aggression strengthen those associations. College student participants (N = 378, 32% males) self-selected into an online study in which they reported on 2 days of alcohol/drug use and on aggression perpetration and victimization (including physical, psychological and electronic aggression, and sexual coercion) with friends and dating partners. Using regression to test for nonequivalence of predictor and outcome variables, we found bidirectional effects for males only. Males' substance use was associated with an increased likelihood on the same day of aggression perpetration and of aggression victimization; males' aggression perpetration and aggression victimization were associated with an increased likelihood of substance use on the same day. Females did not show significant contingencies between substance use and aggression in either direction. Males' attitudes justifying male-to-female aggression were associated with their aggression perpetration and victimization and their justification of female-to-male aggression strengthened the link between substance use and aggression perpetration. With interpersonal aggression and substance use being significant problems on college campuses, many colleges offer separate preventive intervention programs aimed at these public health challenges; this study suggests possible benefits of an integrated approach that addresses connections between alcohol/drug use and aggression.
许多研究记录了物质使用与攻击行为的实施和受害之间的关联；然而，对于大学生在同一天内这些问题行为的同时发生，我们知之甚少。本研究调查了物质使用和攻击行为是否会相互增加发生的可能性，以及是否合理化攻击行为的态度会加强这些关联。大学生参与者（N=378，32%为男性）自行选择参加一项在线研究，他们在其中报告了两天的酒精/药物使用情况，以及与朋友和约会伴侣的攻击行为实施和受害情况（包括身体、心理和电子攻击以及性胁迫）。我们使用回归来检验预测变量和结果变量的等价性，发现只有男性存在双向效应。男性的物质使用与当天攻击行为实施和受害的可能性增加有关；男性的攻击行为实施和受害与当天物质使用的可能性增加有关。女性在任何方向上都没有显示出物质使用和攻击行为之间的显著关联。男性合理化男性对女性攻击的态度与他们的攻击行为实施和受害以及他们合理化女性对男性攻击的态度与物质使用和攻击行为实施之间存在联系。由于人际攻击和物质使用是大学校园中的重大问题，许多学院都提供了针对这些公共卫生挑战的单独预防干预计划；这项研究表明，解决酒精/药物使用和攻击行为之间联系的综合方法可能具有益处。
