Event history calendars (EHCs) are frequently used in social measurement to capture important information about the time ordering of events in people's lives, and enable inference about the relationships of the events with other outcomes of interest. To date, EHCs have primarily been designed for face-to-face or telephone survey interviewing, and few calendar tools have been developed for more private, self-administered modes of data collection. Web surveys offer benefits in terms of both self-administration, which can reduce social desirability bias, and timeliness. We developed and tested a web application enabling the calendar-based measurement of contraceptive method use histories. These measures provide valuable information for researchers studying family planning and fertility behaviors. This study describes the development of the web application, and presents a comparison of data collected from online panels using the application with data from a benchmark face-to-face survey collecting similar measures (the National Survey of Family Growth).
事件史日历（EHCs）常用于社会测量，以获取有关人们生活中事件时间顺序的重要信息，并推断这些事件与其他感兴趣结果之间的关系。迄今为止，EHCs主要设计用于面对面或电话调查访谈，很少有日历工具是为更私密的自我管理数据收集模式而开发的。网络调查在自我管理方面具有优势，这可以减少社会期望偏差，并且具有及时性。我们开发并测试了一个网络应用程序，用于基于日历测量避孕方法使用历史。这些测量为研究计划生育和生育行为的研究人员提供了有价值的信息。本研究描述了该网络应用程序的开发过程，并比较了使用该应用程序从在线样本收集的数据与从收集类似测量数据的基准面对面调查（全国家庭成长调查）的数据。
