DESCRIPTION (provided by applicant): The goal of this study is to identify risk and vulnerability mechanisms for alcohol and marijuana use-related problems among college students. Use of alcohol and marijuana is prevalent among college students. Use of these drugs increases the potential for a broad range of psychosocial problems. Research indicates both common and divergent risk mechanisms for substance use and use-related problems. This project aims to examine the association of four risk variables (impulsivity, affect lability, drug consumption, and perceived utility of substance use in achieving personal goals) with problems associated with marijuana and alcohol use among college students. These variables have all been linked to substance use problems in cross-sectional research. This study will explore relationships with a prospective longitudinal design. College students (n=800) will be recruited through e-mail and fliers on campus. Participants will be assessed at two time points separated by a period of six months. All questionnaires will be completed online in reserved computer labs in small group sessions under the supervision of a research assistant. All responses will be anonymous and participants will be identified only by a unique self-generated code. Analyses will focus on the subset of students who report using alcohol (85 percent) or marijuana (25 percent) during the six-month assessment window. Three types of relationships will be examined. The first relationship is an indirect path in which the association between the risk variable and use-related problems is mediated by use frequency. The second, is a direct path in which the risk variable contributes to use-related problems independently of use frequency. The significance of the direct and indirect paths will be determined by a structural equation model. Third, a vulnerability mechanism will be examined. In addition to a direct effect, impulsivity is hypothesized to be a vulnerability factor, moderating the relationship between use-related problems and drug consumption. Moderating effects will be determined by multiple regression models. Better understanding of the etiological paths of substance use problems may be useful for early identification of individuals at risk for substance use problems and may inform the development of effective interventions.

描述（由申请人提供）：本研究的目的是识别风险 酒精和大麻使用相关问题的脆弱性机制 在大学生中。酒精和大麻的使用在大学中很普遍 学生这些药物的使用增加了广泛的 心理问题研究表明，共同和不同的风险 物质使用和使用相关问题的机制。该项目旨在 检查四个风险变量（冲动，情感不稳定， 药物消费，以及物质使用在实现个人 目标）与大麻和酒精使用相关的问题， 学生这些变量都与药物使用问题有关， 横截面研究。这项研究将探讨与一个 前瞻性纵向设计。将招募大学生（n=800） 在校园里发邮件和传单参与者将在两个时间进行评估 各点之间相隔六个月。所有问卷将 在网上完成的保留计算机实验室在小组会议下， 研究助理的监督。所有回复均为匿名， 参与者将仅通过独特的自我生成代码进行识别。分析 将重点关注报告使用酒精的学生（85%）或 大麻（25%）在六个月的评估窗口。三种类型的 关系将被审查。第一种关系是间接的， 风险变量与使用相关问题之间的关联是 通过使用频率进行调节。第二，是一条直接的路径， 变量导致与使用相关的问题，与使用频率无关。 直接路径和间接路径的重要性将由 结构方程模型第三，将审查脆弱性机制。 除了直接的影响，冲动被假设是一个 脆弱性因素，调节使用相关问题之间的关系 和毒品消费。调节效应将由多个 回归模型更好地理解物质的病因学途径 使用问题可能有助于早期识别有风险的个体， 物质使用问题，并可能为制定有效的 干预措施。
