由访谈者进行的调查是收集人口一级流行病学数据的一个重要方法，但受到答复率下降和费用增加的影响。网络调查提供了更快的数据收集和更低的成本。然而，人们对网络调查的数据质量表示关切。以前的研究主要集中在选择偏差上，很少有人探索测量差异。本文旨在评估模式对同一受访者在两个时间点给出的回答的影响程度，并提供有关未来使用网络调查时潜在测量误差的信息。来自第三次英国性态度和生活方式全国调查（Natsal-3）的527名参与者，使用计算机辅助个人访谈（CAPI）和自我访谈（CASI）模式，随后在网络调查中回答了措辞相同的问题。McNemar检验评估了个体内反应的差异是随机的还是表明了模式效应，即在一种模式下报告更敏感反应的比例更高。通过广义估计方程对汇总答复进行分析，探讨了性别和问题类型对变化的影响。只有10%的回答在两次调查之间发生了变化。然而，约三分之一的变量发现了模式效应，与Natsal-3相比，在网络上更常见的敏感反应的报告更高。网络似乎是敏感行为调查的一种有前途的模式，最有可能是混合模式设计的一部分。我们的研究结果表明，模式效应可能会有所不同的问题类型和内容，以及所使用的模式的特定组合。混合模式调查需要仔细发展，以了解模式效应和如何解释它们。
Interviewer-administered surveys are an important method of collecting population-level epidemiological data, but suffer from declining response rates and increasing costs. Web surveys offer more rapid data collection and lower costs. There are concerns, however, about data quality from web surveys. Previous research has largely focused on selection biases, and few have explored measurement differences. This paper aims to assess the extent to which mode affects the responses given by the same respondents at two points in time, providing information on potential measurement error if web surveys are used in the future. 527 participants from the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3), which uses computer assisted personal interview (CAPI) and self-interview (CASI) modes, subsequently responded to identically-worded questions in a web survey. McNemar tests assessed whether within-person differences in responses were at random or indicated a mode effect, i.e. higher reporting of more sensitive responses in one mode. An analysis of pooled responses by generalized estimating equations addressed the impact of gender and question type on change. Only 10% of responses changed between surveys. However mode effects were found for about a third of variables, with higher reporting of sensitive responses more commonly found on the web compared with Natsal-3. The web appears a promising mode for surveys of sensitive behaviours, most likely as part of a mixed-mode design. Our findings suggest that mode effects may vary by question type and content, and by the particular mix of modes used. Mixed-mode surveys need careful development to understand mode effects and how to account for them.
