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

描述(由申请者提供)：酒精使用通常被认为会增加性风险，但事件级别关联的经验证据并不一致。这项选择研究将考察酒精使用和性行为的协变，因为它们改变了整个大学的发展，并在不同的关系和情况下发生变化。基于发展语境的观点，SELECTIONS将采用纵向+基于事件的日记设计，结合7个学期(31年半)的大学纵向数据和每个学期5周的事件级别数据。对612名非洲裔美国人、亚裔美国人、欧洲裔美国人和拉美裔美国人的多种族样本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、性行为及其在整个大学中的共同变化的发展轨迹；(2)建立酒精使用和性行为之间的事件级关联模型；以及(3)确定酒精使用、性行为及其关联的个人水平(例如，性别、种族)、发展变化(例如，宗教信仰、饮酒动机)和上下文波动(例如，伴侣特征)的预测因素。除了饮酒和性行为外，后果还包括短期后果、健康事件和学习成绩。分析将解决酒精使用预测性风险的人，在什么情况下，以及这种联系在大学期间是如何发展变化的。纵向和事件级网络调查的自我报告将由调查员编码的本地和校园事件以及高年级的学术记录数据补充。对行为变化的开放式感知将被编码，以补充数量上的…数据/分析将使用潜在增长曲线模型和多水平模型来测试酒精预期模型、酒精近视理论和日常活动对情景偏差的预测。酒精使用和性行为是青少年和初出茅庐的成年人发病和死亡的主要原因。在这一关键时期采取的途径和确立的生活方式可能会影响成年后的健康。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。CHOICES研究将提供有关酒精使用和性行为的发展和情景协同变化的新信息，以及这些联系在多大程度上因个人水平、发育变化和环境变量而不同。这项关于酒精使用是否预示着不同种族大学生样本中的性风险的研究，将通过确定学生的特征和最有可能发生危险行为的情况，为预防和政策制定提供信息。

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.
