网络问卷，包括在混合模式调查中使用的问卷，通常比访谈者管理的问卷产生更高水平的项目无反应。项目不响应通常被视为对数据质量有不利影响。目前的研究考察了使用动机陈述，以减少项目无反应在一个混合模式设计的网络调查组件。对于网络调查和混合模式调查，比较了不同实现的效果。此外，混合模式的结果与面对面的调查进行了比较。目前的研究通过一个独特的大规模随机实验来检验动机陈述时间的影响，并与访谈者管理的背景下的相同调查进行比较，从而增加了关于动机陈述使用的文献。研究结果表明，在一个问题没有得到回答之后，紧接其后的动机陈述的效果大大优于对照或调查中稍后的动机陈述。使用这种即时反应性提示将道具的无反应程度降低到等同于面对面的水平。相反，对照组（无陈述）和后来放置的动机陈述导致更大的项目无反应。被测变量的点估计不受所获得的附加响应的影响。结果表明，在使用网页设计时，减少项目无反应的实际设计意义，特别是有计划地使用反应性动机提示。
Web questionnaires, including those used in mixed-mode surveys, generally produce higher levels of item nonresponse than interviewer-administered questionnaires. Item nonresponse is generally seen as having a detrimental impact on data quality. The current study examines using motivational statements to reduce item nonresponse in a web survey component of a mixed-mode design. The effects of alternative implementations are compared, both for web surveys and for mixed-mode surveys. In addition, the mixed-mode results are compared to a face-to-face survey. The current study adds to the literature on the use of motivational statements by using a unique large-scale randomized experiment to examine the impact of the timing of the motivational statement, and to compare with the same survey in an interviewer-administered context. Findings show that a motivational statement following immediately after an item is left unanswered greatly outperforms either the control or a motivational statement at a later point in the survey. Using this immediate reactive prompt reduces item nonresponse to levels equivalent to a face-to-face version. Conversely, the control (no statement) and later placed motivational statement lead to significantly greater item nonresponse. Point estimates for the tested variables are not affected by the additional responses obtained. The results suggest practical design implications to reduce item nonresponse when using a web design, specifically the use of a reactive motivational prompt in a planned way.
