Mobile phone survey interviewing is becoming increasingly prevalent, so it is important to understand how it affects measurement error. We link cognitive response process theory (Tourangeau et al 2000) to theories of mode effects to build a comprehensive framework that identifies ways in which...

We assess whether the probability of a sample member participating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally...

Pre-election polls sometimes fail to reach the purpose for which they are carried out: to provide accurate predictions of electoral out-comes. By looking at the 2006 Italian General Elections, this paper aims to assess the role that different factors play in determining the accuracy of the...

We conduct two large-scale randomised experiments on the British Household Panel Survey (BHPS) to study methods of reducing panel attrition. The first experiment compares different strategies for tracing and maintaining contact with sample members. We find that change-of-address cards...

We analyse the results of experiments on aspects of the design of questionnaire and interview mode in the 2009 wave of the new UK Understanding Society panel survey. The randomised experiments relate to job- and life-satisfaction questions and vary the labeling of response scales, the mode of...

In face-to-face surveys interviewers play a crucial role in making contact with and gaining cooperation from sample units. While some analyses investigate the influence of interviewers on nonresponse, they are typically restricted to single-country studies. However, interviewer training,...

This paper examines the role of interviewers' experience, attitudes, personality traits and inter-personal skills in determining survey co-operation. We take the perspective that these characteristics influence interviewers' behaviour and hence influence the doorstep interaction between...
