目的：描述在常规接触调查期间从性传播疾病/人类免疫缺陷病毒病例中得出的首次和最后一次性接触报告日期的可靠性，并确定其用于评估并发性的充分性。方法：我们使用了来自 5 项研究的接触者追踪数据，在这些研究中，对 774 名情侣的两名成员进行了访谈，并将彼此指定为性伴侣。我们评估了合作伙伴在第一次和最后一次接触日期方面的协议，这与报告日期的精确度（日、月或年）以及二人的人口统计和行为特征有关。我们进行了模拟，根据观察到的数据引入报告错误，假设伙伴关系的“真实”时间配置，以评估报告不可靠性对并发性测量的影响。结果：32% 的情侣同意第一次性接触的确切日期，36% 的人同意最后一次性接触的日期。 64% 的人在第一次性接触之日起的 30 天内同意，81% 的人在最后一次性接触的日期内同意。报告日期的可靠性与报告的准确性呈正相关。对报告的暴露日期的一致与任何可用的社会人口统计和行为变量没有有意义的关联。根据模拟，在各种条件下，报告日期对估计并发性的正向预测值约为 80%。结论：这些数据表明，报告暴露日期的可靠性相当不错，但用报告日期估计并发性会出现一些错误。需要为此目的而设计的数据，并在充分关注评估并发性的统计和流行病学问题的情况下进行分析。
Objectives: To describe the reliability of reported dates of first and last sexual exposure, as elicited from sexually transmitted disease/ human immunodeficiency virus cases during routine contact investigation, and determine their adequacy for assessing concurrency.Methods: We used contact tracing data from 5 studies in which both members of 774 dyads were interviewed and named each other as sex partners. We assessed partners' agreement on the dates of first and last exposure as related to precision (to the day, month, or year) of reported dates and demographic and behavioral characteristics of the dyad. We performed simulations that introduced reporting error, based on our observed data, to posited "true" temporal configurations of partnerships to assess the impact of unreliability in reporting on the measurement of concurrency.Results: Thirty-two percent of dyads agreed on the exact date of first sexual exposure, and 36% did so for the date of last sexual exposure. Sixty-four percent agreed within 30 days on the date of first sexual exposure, and 81% did so for the date of last sexual exposure. The reliability of reported dates was positively related to the precision of the reports. Agreement on reported exposure dates was not meaningfully associated with any of the sociodemographic and behavioral variables available. Based on simulations, the positive predictive value of reported dates for estimating concurrency is approximately 80% over a wide range of conditions.Conclusions: These data suggest that the reliability of reported exposure dates is reasonably good but that estimating concurrency with reported dates is subject to some error. Data designed for the purpose and analyzed with adequate attention to the statistical and epidemiologic issues of assessing concurrency are needed.
