A mixed methods study of perceived social norms and high-risk alcohol and marijuana use among a diverse sample of young adult community college students

项目摘要 酒精和大麻是中国大学生最常使用的精神活性物质 美国和研究记录了高风险使用的许多严重和长期的负面后果。 几乎所有已发表的关于大学生饮酒和吸食大麻的研究都集中在四年制大学 学生，尽管有统计数据表明，参加两年制社区大学的学生构成了一个庞大且不断增长的群体 美国大学生比例和许多社区大学生从事高风险酒精 以及大麻的使用和经历与物质有关的问题。酒精和大麻的发展 对从事高风险使用的社区大学生进行干预是必要的，然而，需要 更好地了解与在这一特定人群中使用药物相关的风险因素，以识别/适应 干预的目标。先前的研究表明，感知到的描述性和禁制性酒精和大麻 规范是酒精和大麻使用和个性化规范反馈的最强预测因素之一 干预措施被用作独立的酒精干预措施，并作为多组成部分简报的一部分 动机干预，以减少对同伴物质使用和批准使用的规范性误解。 社会心理学与高等教育理论(即社会认同理论和学生参与模式) 建议认同感和学生连接性是社会关系中需要考虑的重要因素 规范和行为。采用混合方法的研究设计，本申请的具体目的是：(1) 定性地探索社会和教育身份、学校人脉和感受到的同伴酒精和 在不同样本的社区大学生中使用大麻，(2)进行有限混合建模以 确定不同类别的酒精和大麻的使用以及所确定的后果和重要相关因素 (3)采用多层次的纵向调查数据 分析以检查使用的短期和长期后果，以及(4)横截面和 规范和使用之间的预期关联以及这些关联的潜在主持人 年轻成人社区大学生的多样化样本。拟议的研究解决了一个重要的差距 通过检查经常被忽视的人群进行的物质使用研究和干预。申请者还将 接受以下方面的高级培训：(1)青少年药物使用和治疗的病因、预防和治疗 研究管理的科学方面，(2)定性和混合方法研究方法和先进 统计方法，(3)青少年药物使用的干预和应用工作，以及(4)科学写作 和传播。

Project Summary Alcohol and marijuana are the most commonly used psychoactive substances among college students in the US and research has documented many acute and long-term negative consequences of high-risk use. Nearly all of the published research on college student drinking and marijuana use focuses on 4-year college students, despite statistics that students attending 2-year community colleges make up a large and growing proportion of college students in the US and that many community college students engage in high-risk alcohol and marijuana use and experience substance-related problems. The development of alcohol and marijuana interventions are warranted for community college students engaging in high-risk use, however, there needs to be a better understanding of risk factors associated with use among this particular population to identify/adapt targets of intervention. Prior research suggests that perceived descriptive and injunctive alcohol and marijuana norms are among the strongest predictors of alcohol and marijuana use and personalized normative feedback interventions have been used as stand-alone alcohol interventions and as part of multi-component brief motivational interventions to reduce normative misperceptions of peer substance use and approval of use. Social psychology and higher education theories (i.e., Social Identity Theory and Student Involvement Model) suggest identity and student connectedness are important factors to consider in the relationship between social norms and behavior. Using a mixed methods research design, the specific aims of this application are: (1) qualitatively explore social and educational identity, school connectedness, and perceived peer alcohol and marijuana use among a diverse sample of community college students, (2) conduct finite mixture modeling to identify distinct classes of alcohol and marijuana use and consequences and important correlates of identified classes among young adult community college students, (3) use longitudinal survey data with multilevel analyses to examine short- and longer-term consequences of use, as well as (4) cross-sectional and prospective associations between norms and use and potential moderators of these associations among a diverse sample of young adult community college students. The proposed study addresses an important gap in substance use research and intervention by examining an often ignored population. The applicant will also receive advanced training in: (1) etiology, prevention, and treatment of young adult substance use and scientific aspects of study management, (2) qualitative and mixed method research methods and advanced statistical methods, (3) interventions and applied work for young adult substance use, and (4) scientific writing and dissemination.
