We mailed a health survey to the 18,408 residents of a California retirement community and compared the 11,550 respondents on a number of characteristics by time of response. Early respondents were more likely to be the "worried well," that is, healthy individuals who see their doctor regularly, receive disease detection screening, and follow healthful life-style practices. Late respondents tended to answer questions regarding their mental function and emotional status more negatively. Early and late respondents did not differ in the rates of death or hospitalization during the first 5 years of the study; nonrespondents had a higher incidence of hospitalization than respondents in year 1 and higher death rates in the first 3 years, but not thereafter.
我们向加利福尼亚一个退休社区的18408名居民邮寄了一份健康调查问卷，并根据回复时间，对11550名受访者的若干特征进行了比较。早期受访者更有可能是“忧心健康者”，即那些定期看医生、接受疾病检测筛查并遵循健康生活方式的健康个体。晚期受访者在回答有关其心理功能和情绪状态的问题时往往更为消极。在研究的前5年中，早期和晚期受访者的死亡率或住院率并无差异；未回复者在第1年的住院率高于受访者，在头3年的死亡率也更高，但此后并非如此。
