样本单位拒绝和不联系样本单位都会造成调查无反应偏差。然而，在这两种情况下，贡献的性质可能会有很大的不同。扩大实地努力可能会减少无反应偏差的一种或两种成分。我们考察了来自英国的几项调查的数据，这些调查涉及更广泛的领域努力，以及它们似乎对无反应偏差及其组成部分的影响。发现了一些一致的模式。我们还探讨了这种分析对扩大努力的业务定义的敏感性。这一发现提供了一些证据，证明了拒绝转换和重复联系尝试在减少无反应偏见方面的相对作用。这项研究还对制定适当的实地战略以打击无反应偏见具有重要意义。
Refusal by sample units and failure to contact sample units can both contribute to survey non-response bias. However, the nature of the contribution can be rather different in the two cases. Extended field efforts may reduce either or both components of non-response bias. We examine data from several UK surveys on extended field efforts and the effect that they appear to have on non-response bias and its components. Some consistent patterns are found. We also explore the sensitivity of such analyses to the operational definition of extended efforts. The findings provide some evidence of the relative roles of refusal conversion and repeated contact attempts in reducing non-response bias. The study also has implications for the development of appropriate field strategies to combat non-response bias.
