目的：探讨进食障碍行为两阶段流行病学研究中的无应答偏倚。方法：自报问卷发放到社区样本的妇女年龄在18-45岁的选民名册。完成了对一组答复者的后续访谈。在研究的第一阶段，在早期（n = 259）和晚期（n = 71）的受访者之间，以及在第二阶段，在完成访谈的个人（n = 208）和拒绝接受访谈的个人（n = 63）之间，比较了进食障碍的精神病理学、一般身心健康和社会人口学特征。结果如下：关于进食障碍的精神病理学水平，以及所有其他措施，在研究的第一阶段，只有在反复提醒后才做出回应的人与那些对最初邮件做出回应的人没有区别，拒绝接受采访的人与完成采访的人没有区别。结论：拒绝接受采访的个体之间的无应答偏倚不太可能在进食障碍的两阶段流行病学研究中造成问题。需要进一步研究来检查此类研究第一阶段非受访者的特征。(C)出版社：Wiley Periodicals，Inc.
Objective: To investigate nonresponse bias in a two-phase epidemiologic study of eating-disordered behavior. Method: Self-report questionnaires were delivered to a community sample of women aged 18-45 drawn from the electoral roll. Follow-up interviews were completed with a subgroup of respondents. Eating disorder psychopathology, general physical and mental health, and sociodemographic characteristics were compared among early (n = 259) and late (n = 71) respondents at the first phase of the study and among individuals with whom interviews were completed (n = 208) and individuals declining to be interviewed (n = 63) at the second phase. Results: With respect to levels of eating disorder psychopathology, and on all other measures, individuals who responded at the first phase of the study only after repeated reminders did not differ from those who responded to the initial mailout, and individuals who declined to be interviewed did not differ from individuals with whom interviews were completed. Conclusions: Nonresponse bias among individuals declining to be interviewed is unlikely to pose a problem in two-phase epidemiologic studies of eating disorders. Further research is needed to examine the characteristics of nonrespondents at the first phase of such studies. (C) 2004 by Wiley Periodicals, Inc.
