The present analysis examined sample attrition in a one-year longitudinal health survey that made use of telephone follow-up interviews (N = 1210). Overall, respondent attrition had little impact on the sociodemographic and health status characteristics of the sample at the final interview. However, certain subgroups were statistically less likely to participate in the follow-up interviews, including younger respondents, the non-employed, people from the lower socioeconomic groups, and those who initially rated their health as fair or poor. Reports of physical illness and disability obtained at the initial interview were unrelated to rates of sample attrition.
本分析在一项为期一年的纵向健康调查中研究了样本损耗情况，该调查采用电话随访访谈（N = 1210）。总体而言，受访者损耗对最终访谈时样本的社会人口统计学和健康状况特征影响不大。然而，某些亚组在统计学上参与随访访谈的可能性较小，包括年轻受访者、未就业者、社会经济地位较低群体的人，以及那些最初将自己的健康状况评为一般或较差的人。在初次访谈中获得的身体疾病和残疾报告与样本损耗率无关。
