目标
人们对未完成健康问题电话调查的影响知之甚少。本文确定了一种很少被研究的不完成的来源，即被动拒绝，并评估了它与其他两个来源（不合作和不接触）对不完成偏差的贡献。被动拒绝包括反复要求回电的受访者和访谈员反复遇到答录机的家庭。
方法
通过奥兰治县健康调查对 4893 名受访者收集了不完成指标（不合作、被动拒绝和不接触）、人口和社会经济特征、健康风险因素以及医疗保健获取和健康状况指标。调查通过随机数字拨号进行抽样，并通过计算机辅助电话进行访谈。
结果
被动拒绝会对完成率和未完成造成的偏差产生重大影响。常用的完成率定义可能会低估由于未完成而产生的偏差，因为它们忽略了被动拒绝。在我们控制人口和社会经济因素后，选定的健康指标几乎没有出现未完成偏差。
结论
这些结果表明完成率的报告得到了改进，并支持研究电话健康调查中未完成情况的多变量框架。
OBJECTIVES
Little is known about the effect of noncompletion on telephone surveys of health issues. This paper identifies a little-studied source of noncompletion, passive refusal, and evaluates its contribution to noncompletion bias along with two other sources: noncooperation and noncontact. Passive refusals include respondents who repeatedly request callbacks and households where interviewers repeatedly encounter an answering machine.
METHODS
Measures of noncompletion (noncooperation, passive refusal, and noncontact), demographic and socioeconomic characteristics, health risk factors, and indicators of health care access and health status were collected through the Orange County Health Surveys on 4893 respondents. The surveys sampled by random-digit dialing and interviewed by computer-assisted telephone.
RESULTS
Passive refusals have a substantial impact on completion rates and bias due to noncompletion. Commonly used definitions for completion rates may underestimate the bias due to noncompletion because they omit passive refusals. After we controlled for demographic and socioeconomic factors, few noncompletion biases appeared on selected health indicators.
CONCLUSIONS
These results suggest improved reporting of completion rates and support a multivariate framework for studying noncompletion in telephone health surveys.
