DESCRIPTION (provided by applicant): The overarching objective of the proposed research is a multi-level examination of sexual concurrency and mixing patterns among U.S. men and women. Specifically, we will examine: (1) the patterns of concurrent partnerships, and gender differences in these patterns as a function of individual, relationship, and community characteristics; (2) the individual, relationship, and community characteristics associated with the risk of entry and exit from concurrent partnerships; and gender differences in the effects of these characteristics on that risk; (3) the differences between continually monogamous and initial concurrent partnerships and between initial concurrent and secondary concurrent partnerships with respect to partner characteristics (i.e., mixing patterns) and HIV-risk sexual behaviors, including alcohol and drug use prior to and with sex. We have two corollary aims. These are, to examine: (4) the cross-sectional change in the patterns of concurrent partnerships over time, and the change in the effects of individual, relationship, and community characteristics on the likelihood of formation and dissolution of concurrent partnerships; and (5) the cross-sectional change, overtime, in HIV-risk sexual behaviors, including alcohol and drug use, within different types of partnerships, and the change in the effects of these characteristics on HIV-risk sexual behaviors. We will use data from four national surveys of men and women: The 2002 National Survey of Family Growth (NSFG), the 1996 National Sexual Health Survey (NSHS), and the 1991 National Survey of Men (NSM) and the National Survey of Women (NSW). The research is guided by the expectancy-value theory, and the analyses are based on a modified version of the Subjective Expected Utility model, hi the analysis of the risk of entry into and exit from concurrent partnerships we will use hazard models. Binary outcome measures will be analyzed using logistic regression. The analysis of risk perceptions which are ordered scales will use ordered logit models. When the outcomes measures are nominal unordered categories we will use multinomial logit models, and when the outcome measures are skewed toward zero we will use tobit models, which can incorporate information on the proportion of the sample with outcomes of zero.

描述(由申请人提供)： 这项拟议的研究的首要目标是对美国男性和女性的性并发和混合模式进行多层次的检查。具体地说，我们将研究：(1)同时伙伴关系的模式，以及这些模式中的性别差异作为个人、关系和社区特征的函数；(2)与进入和退出同时伙伴关系的风险相关的个人、关系和社区特征；以及这些特征对风险影响的性别差异；(3)持续的一夫一妻制和最初的同时伙伴关系之间以及最初的同时伙伴关系和第二次同时伙伴关系之间在伴侣特征(即混合模式)和艾滋病毒风险性行为方面的差异，包括在性行为之前和性行为中使用酒精和药物。我们有两个必然的目标。这些是：(4)同时伙伴关系模式随时间的横向变化，以及个人、关系和社区特征对同时伙伴关系形成和解散可能性的影响的变化；(5)不同类型伙伴关系中包括酒精和药物使用在内的艾滋病毒危险性行为的横向变化，以及这些特征对艾滋病毒危险性行为影响的变化。我们将使用四项全国性男女调查的数据：2002年全国家庭增长调查(NSFG)、1996年全国性健康调查(NSHS)、1991年全国男性调查(NSM)和全国妇女调查(NSW)。本研究以期望值理论为指导，分析基于主观期望效用模型的修正版本，在分析进入和退出兼营伙伴关系的风险时，我们将使用风险模型。将使用Logistic回归分析两种结果衡量标准。对有序尺度的风险感知的分析将使用有序的Logit模型。当结果度量是名义无序类别时，我们将使用多项Logit模型，而当结果度量偏向于零时，我们将使用Tobit模型，该模型可以纳入关于结果为零的样本比例的信息。
