Abstract Interviewer characteristics are usually assumed fixed over the fieldwork period. The number of sample units that require the interviewers’ attention, however, can vary strongly over the fieldwork period. Different workload levels produce different constraints on the time interviewers have available to contact, recruit and interview each target respondent, and may also induce different motivational effects on interviewers’ behavior as they perform their different tasks. In this article we show that fine-grained, time-varying operationalizations of project-specific workload can be useful to explain differences in interviewers’ field efforts and achieved response outcomes over the fieldwork period. We derive project-specific workload for each interviewer on each day of fieldwork in two rounds of the European Social Survey in Belgium from contact history and assignment paradata. Project-specific workload is measured as (1) the number of sample units which have been and remain assigned on any day t (assigned case workload), and (2) the number of sample units for which interviewer activity has started and not yet ceased on any day t (active case workload). Capturing temporal variation in interviewers’ workloads in a direct way, the time-varying operationalizations, are better predictors than are the interviewer-level operationalizations of typical (active or potential) workload that are derived from them, as well as the traditional total-count workload operationalization.

调查中采访者工作量的测量以及工作量对采访者实地调查工作和绩效的影响

摘要通常认为采访者的特征在田野调查期间是固定的。但是,需要访谈员注意的样本单位数量在实地调查期间可能会有很大差异。不同的工作量水平对访问者可用来联系,招募和采访每个目标受访者的时间产生了不同的限制,并且还可能在访问者执行其不同任务时对访问者的行为产生不同的动机影响。在本文中,我们表明,针对特定项目的工作负载的细粒度,时变的操作性可以用于解释访调员在现场工作中的差异以及在现场工作期间所获得的响应结果。我们根据联系历史和工作分配数据,在比利时进行的两轮欧洲社会调查中,在田野调查的每一天为每个访调员得出了特定于项目的工作量。特定于项目的工作量的度量方式是:(1)在第t天已经分配和保持分配的样本单位数(分配的案例工作量);以及(2)访调员活动已经开始但尚未停止的样本单位数。在任何一天(活动案例工作量)。直接捕获采访者工作量的时间变化(随时间变化的操作性)是比从中得出的典型(活动或潜在)工作量的采访者级操作性以及传统总计数更好的预测指标工作负载操作化。特定于项目的工作量的度量方式是:(1)在第t天已经分配和保持分配的样本单位数(分配的案例工作量);以及(2)访调员活动已经开始但尚未停止的样本单位数。在任何一天(活动案例工作量)。与直接从访问者那里获得的典型(活动或潜在)工作量的访问者级别的操作性以及传统的总计数相比,直接捕获访问者的工作量的时间变化(时变的操作性)是更好的预测指标工作负载操作化。特定于项目的工作量的度量方式是:(1)在第t天已经分配和保持分配的样本单位数(分配的案例工作量),以及(2)访调员活动已经开始但尚未停止的样本单位数。在任何一天(活动案例工作量)。直接捕获采访者工作量的时间变化(随时间变化的操作性)是比从中得出的典型(活动或潜在)工作量的采访者级操作性以及传统总计数更好的预测指标工作负载操作化。
