Internet Interviewing and the HRS

我们申请资助一个为期五年的项目，对健康与退休研究（HRS）的一部分受访者进行两次互联网访谈，并建立一个由1,000名非HRS受访者组成的独立互联网小组，他们将在四年内每年通过互联网接受两次访谈，另加一个由500名非HRS受访者组成的对照组，他们将在四年内每年通过电话接受一次访谈。数据收集和分析将告知HRS互联网面试的潜力，并可作为HRS的测试样本。我们提出的研究涵盖了方法论问题和实质性问题，最重要的是在经济学，认知心理学和流行病学。鉴于目前互联网接入在人口中的分布情况（老年人群体的接入率下降），预计在可预见的未来，人力资源服务部将在使用其他方式的同时使用互联网访谈。这激发了所提出的研究的混合模式设计。具体来说，我们的目标是：1。 提供数据，以便对互联网受访者和电话受访者进行比较研究，目的是了解选择偏差; 2.提供更有系统的观点，以比较互联网访问与其他收集调查数据的方式，特别是中年和老年受访者; 3。在问卷和问题设计方面进行各种实验，开发网络访谈的潜力。将特别注意认知功能的作用和互联网作为面试环境的适宜性。4.改善对消费或财富等各种重要客观变量的衡量; 5.为复杂的可能主观的变量，如概率，期望，健康史，风险态度和时间偏好开发新的测量方法; 6。将这些活动产生的数据提供给研究界。从2004年起，将研究成果与人力资源系统部分和逐步实施互联网访谈相结合。

We request funding for a five year proj4ect to conduct two Internet interviews with a subset of the respondents to the Health and Retirement Study (HRS), and to set up a separate Internet panel of 1,000 non-HRS respondents, who will be interviewed via Internet twice a year for four years, plus a control group of 500 non-HRS respondents, who will e interviewed once a year by telephone for four years. The data collection and analysis will inform the HRS about the potential of Internet interviewing and may serve as a tested sample for the HRS. Our proposed study covers both methodological issues and substantive issues, foremost in economics, cognitive psychology and epidemiology. In view of the current distribution of Internet access among the population (with access dropping of among older age groups), it is anticipated that in the foreseeable future the HRS will use Internet interviewing alongside other modes. This motivates the mixed mode design of the proposed study. Specifically, we aim: 1. To provide data that will permit a comparative study of the population of Internet interviewees with the population of telephone interviewees with the goal of understanding selection bias; 2. To provide more systematic insight in the properties of Internet interviewing in comparison with other modes of collecting survey data, in particular among middle aged and elderly respondents; 3. To initiate various experiments in questionnaire and question design, exploiting the potential of Internet interviewing. Special attention will be paid to the role of cognitive functioning and the suitability of the Internet as an interviewing environment. 4. To improve the measurement of various important objective variables such as consumption or wealth; 5. To develop new measurement methods for complex possibly subjective variables such as probabilities, expectations, health histories, risk attitudes and time preferences; 6. To make the data generated by these activities available to the research community. To gear the outcomes of the research towards partial and gradual implementation of Internet interviewing in the HRS as of 2004.
