This paper examines the concordance of reported shared sexual behaviors, including condom use, among 535 heterosexual, African American, serodiscordant couples and identifies factors that might predict discordant reports. Percentages of agreement, Kappa and McNemar's statistics and conditional probability indices are used to measure concordance. Logistic regression models identify predictors of couples' discordant sexual reports. Analyses revealed Kappa statistics for reporting anal sex, fellatio and cunnilingus indicated moderate to substantial agreement. The effects of demographics and the couples' relationship contexts on concordance of reported sexual behaviors were found to vary somewhat by gender and type of sexual behavior. Findings showed that concordance of reporting between the couples was consistent for the past 90 and 30 days. Findings from this paper provide new scientific insights into the knowledge base of self-reported couples' data and suggest that these data can be used to evaluate their accuracy and serve as a proxy for validity.
本文考察了 535 对异性恋、非裔美国、血清不一致的夫妇报告的共享性行为（包括 condom 使用）的一致性，并确定了可能预测不一致报告的因素。使用百分比一致性、Kappa 和 McNemar 的统计数据和条件概率指数来衡量一致性。逻辑回归模型确定了夫妇不一致性性报告的预测因素。分析显示，报告肛交、口交和阴交的 Kappa 统计数据表明存在中度至大量的一致性。研究结果表明，人口统计学和夫妻关系背景对报告性行为一致性的影响因性别和性行为类型而异。研究结果表明，过去 90 天和 30 天内，夫妇之间的报告一致性一致。本文的研究结果为自我报告的夫妇数据知识库提供了新的科学见解，并表明这些数据可用于评估其准确性，并作为有效性的替代指标。
