许多健康状况调查是为邮件、电话或亲自管理而设计的。然而，除了极少数例外，调查人员没有研究调查管理模式对受访者评估其健康状况的方式和其他重要参数（如应答率，无应答偏倚和数据质量）的影响，这可能会影响结果的普遍性。我们使用来自综合社会调查的非机构化成年人的全国抽样框架，随机分配成年人进行邮件调查（80%）或计算机辅助电话调查（20%）。这些调查旨在为SF-36健康调查提供国家规范。电话调查每例的总数据收集成本（47.86美元）比邮件调查（27.07美元）高77%。在被随机分配到邮件的受访者中，回复率（79.2%）明显高于电话调查（68.9%）。无应答偏倚在两种模式中都很明显，但除年龄外，两种模式之间没有差异。邮件回复的缺失率高于电话回复（1.59对0.49）。基于SF-36量表的健康评级不太有利，慢性疾病的报告更频繁，邮件比电话受访者。结果进行了讨论，在选择一种调查方法的健康状况评估应用程序中所涉及的权衡。提供了SF-36调查的邮件和电话版本的标准，用于解释个人和团体评分。
Many health status surveys have been designed for mail, telephone, or in-person administration. However, with rare exception, investigators have not studied the effect the survey mode of administration has on the way respondents assess their health and other important parameters (such as response rates, nonresponse bias, and data quality), which can affect the generalizability of results. Using a national sampling frame of noninstitutionalized adults from the General Social Survey, we randomly assigned adults to a mail survey (80%) or a computer-assisted telephone survey (20%). The surveys were designed to provide national norms for the SF-36 Health Survey. Total data collection costs per case for the telephone survey ($47.86) were 77% higher than that for the mail survey ($27.07). A significantly higher response rate was achieved among respondents randomly assigned to the mail (79.2%) than telephone survey (68.9%). Nonresponse bias was evident in both modes but, with the exception of age, was not differential between modes. The rate of missing responses was higher for mail than telephone respondents (1.59 vs. 0.49 missing items). Health ratings based on the SF-36 scales were less favorable, and reports of chronic conditions were more frequent, for mail than telephone respondents. Results are discussed in light of the trade-offs involved in choosing a survey methodology for health status assessment applications. Norms for mail and telephone versions of the SF-36 survey are provided for use in interpreting individual and group scores.
