A Motivational Perspective on Alcohol Use and Sexual Behavior

描述(由申请人提供)：基于动机的干预方法的不断扩大的市场要求对预期和动机在行为参与和行为后果中的作用有具体的了解。尽管人们对大量饮酒和新兴成年人的危险性行为之间的双向影响感到担忧，但很少有研究具体说明这两个领域中个人动机之间的联系，也没有研究这些行为在事件层面上的共同发生。基于理性行为理论，目前的研究计划旨在提高对饮酒动机和性行为之间的关联的理解。数据将由连续14天收集的大学新生在线自我报告组成。密集的日常数据可以调查行为及其后果的事件级关联，包括对人内影响的建模(例如，一个人是否更有可能在他喝酒的日子发生性行为)，这将补充现有的文献，这些文献在很大程度上依赖于以变量为中心的横截面数据。具体目标是：(A)使用聚类分析确定具有支持和反对饮酒和性行为动机的特征特征的个人群体；以及(B)使用多层次模型评估基于与性有关的酒精预期的酒精和性行为后果的每日波动和协变。重要的是要了解个人饮酒和性行为的动机是如何相似或不同的，以及积极和消极的情况在人的一天中可能会或不会一起变化。随着人们对饮酒和性行为的积极和消极后果的动机有了更好的理解，基于动机的简短干预措施是否可以同时针对这些行为将变得更加清楚，这些干预旨在通过减少与大学校园饮酒(例如伤害、酒精中毒)和性行为(例如性传播疾病、意外怀孕)相关的危害来促进公共健康。

DESCRIPTION (provided by applicant): The expanding market for motivation-based approaches to intervention demands specific knowledge of the role of expectancies and motivations in behavior engagement and behavioral consequences. Despite concerns over bidirectional influences between heavy alcohol use and risky sexual behavior among emerging adults, little research has either specified the links between individual motivations in these two domains or examined the event-level co-occurrence of these behaviors. Based on the theory of reasoned action, the current research plan is designed to improve understanding of the associations of the motivations for alcohol use and sex. Data will consist of web-based self-reports from college freshmen collected across 14 consecutive days. Intensive daily data allows investigation of event-level associations of behaviors and their consequences, including the modeling of within-person effects (e.g., whether an individual is more likely to have sex on days he has been drinking) which will supplement existing literature which has largely relied on variable-centered, cross-sectional data. Specific aims are: (a) to identify groups of individuals with characteristic profiles of motivations for and against drinking and sexual behavior using cluster analysis; and (b) to assess daily fluctuations and co-variations in alcohol and sexual behavior consequences based on sex-related alcohol expectancies using multi-level modeling. It is important to understand both how individuals' motivations may be similar or different for drinking and sex and how thteir positive and negative conseuqences may or may not vary together within-people across days. As motivations based on positive and negative consequences of drinking and sex are better understood, it will become clearer whether these behaviors could be targeted together in motivation-based brief interventions designed to promote public health by reducing the harm associated with alcohol use (e.g., injury, alcohol poisoning) and sexual behavior (e.g., STDs, unwanted pregnancy) on college campuses.
