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

描述（由申请人提供）：通常认为饮酒会增加性冒险行为，但事件级关联的经验证据并不一致。“选择”研究将考察酒精使用和性行为之间的共同变异，因为它们在大学期间以及在关系和情况下的发展变化。基于发展背景的视角，CHOICES将采用纵向和基于事件的日记设计，结合大学7个学期（31年半）的纵向数据和每学期5周的事件级数据。612名非裔美国人、亚裔美国人、欧裔美国人和拉丁裔美国人的多种族大学生将完成一系列基于网络的调查。具体目的是：(1)追踪大学生饮酒、性行为的发展轨迹及其共变；(2)酒精使用与性行为之间的事件水平关联模型；(3)确定个人水平（如性别、种族）、发展变化（如宗教信仰、饮酒动机）和环境波动（如伴侣特征）的酒精使用、性行为预测因素及其关联。除了饮酒和性行为外，结果还包括短期后果、健康事件和学习成绩。分析将涉及哪些人饮酒预示着性冒险，在什么情况下，以及这种联系在大学期间如何发展变化。纵向和事件级网络调查的自我报告将由调查人员编码的本地和校园事件以及大四的学习记录数据补充。对行为变化的开放式感知将被编码，以补充定量的……数据/分析将测试来自酒精预期模型、酒精近视理论的预测，以及使用潜在增长曲线模型和多层次模型从日常活动角度对情境偏差的预测。酒精使用和性行为是青少年和初成人发病和死亡的主要原因。在这一关键时期所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。很少有纵向研究集中追踪了多种族新成年样本的酒精使用和性行为。CHOICES研究将提供关于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、发育变化和环境变量而变化的程度。在一个种族多样化的大学生样本中，这项关于酒精使用是否预测性风险的研究，将通过确定学生的特征和最容易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.
