Alcohol Use and Sex in College: Developmental Change and Situational Fluctuations

描述（由申请人提供）：酒精的使用通常被认为会增加性风险，但事件水平关联的经验证据是不一致的。选择研究将研究酒精使用和性行为的共同变化，因为它们在大学和背景下的关系和情况下改变了发展。基于发展背景的角度来看，选择将利用纵向加事件为基础的日记设计结合纵向数据跨越7个学期（31/2年）的大学和事件水平的数据跨越5周每学期。612名非洲裔美国人、亚裔美国人、欧洲裔美国人和拉丁裔美国人的新兴成人大学生将完成一系列基于网络的调查。具体目标是：（1）跟踪酒精使用，性行为及其在大学中的共同变化的发展轨迹;（2）模拟酒精使用和性行为之间的事件水平关联;（3）确定人的水平（例如，性别，种族），发展变化（例如，宗教信仰，饮酒动机），以及上下文波动（例如，伴侣特征）预测酒精使用，性行为及其关联。除了酒精使用和性行为，结果还包括短期后果，健康事件和学业成绩。分析将解决酒精使用预测性风险的人，在什么情况下，以及这种关联如何在大学期间发展变化。从纵向和事件层面的网络调查的自我报告将补充由教师编码的本地和校园活动，并通过高年级的学业成绩数据。对行为变化的开放式感知将被编码，以补充定量分析。数据/分析将使用潜在增长曲线模型和多水平模型测试酒精预期模型、酒精近视理论和常规活动对情境偏差的预测。饮酒和性行为是青少年和新生儿发病和死亡的主要原因。在这一关键时期采取的途径和建立的生活方式可能会影响整个“成年期”的健康。很少有纵向研究深入跟踪新兴成年人的多种族样本的酒精使用和性行为。选择研究将提供有关酒精使用和性行为的发展和情境共变的新信息，以及这些联系因个人水平、发展变化和环境变量而异的程度。这项研究是否酒精使用预测性风险采取在种族多样性样本的大学生将告知预防和政策制定，确定学生的特点和最危险的行为的情况。

DESCRIPTION (provided by applicant): Alcohol use is often assumed to increase sexual risk taking, but empirical evidence for event-level associations is inconsistent. The CHOICES study will examine the co-variation of alcohol use and sexual behavior as they change developmental^ across college and contextually across relationships and situations. Based on a developmental contextual perspective, CHOICES will utilize a longitudinal plus event- based diary design combining longitudinal data across 7 semesters (31/2 years) of college and event-level data across 5 weeks each semester. A multi-ethnic sample of 612 African American, Asian American, European American, and Latino American emerging adult college students will complete a series of web- based surveys. Specific aims are to: (1) Track developmental trajectories of alcohol use, sexual behavior, and their co-variation across college; (2) Model event-level associations between alcohol use and sexual behavior; and (3) Identify person-level (e.g., gender, ethnicity), developmentally-changing (e.g., religiosity, drinking motivations), and contextually-fluctuating (e.g., partner characteristics) predictors of alcohol use, sexual behavior, and their associations. In addition to alcohol use and sexual behaviors, outcomes will include short-term consequences, health events, and academic performance. Analyses will address for whom alcohol use predicts sexual risk taking, under what circumstances, and how this association changes developmentally across the college years. Self-reports from the longitudinal and event-level web surveys will be supplemented by investigator-coded local and campus events and by academic record data through senior year. Open-ended perceptions of change in behavior will be coded to complement the quantitative ... data/Analyses will test predictions from alcohol expectancy models, alcohol myopia theory, and a routine activities perspective on situational deviance using latent growth curve modeling and multi-level models. Alcohol use and sexual behavior are primary causes of morbidity and mortality for adolescents and emerging adults. Pathways taken and lifestyles established during this pivotal period may impact health throughout " adulthood. Little longitudinal research has intensively tracked the alcohol use and sexual behaviors of multi- ethnic samples of emerging adults. The CHOICES study will provide new information about the developmental and situational co-variation of alcohol use and sexual behavior, and the extent to which these links vary by person-level, developmentally-changing, and environmental variables. This examination of whether alcohol use predicts sexual risk taking within an ethnically-diverse sample of college students will inform prevention and policy development by identifying characteristics of students and of situations most at risk for hazardous behaviors.
