Typically, longitudinal survey managers send ‘keep in touch’ mailings to sample members between waves to help minimise non-response through failure to locate individuals at future waves. This paper reports the results from a randomised experiment to impro... see more

Longitudinal surveys are valuable tools for investigating health and social outcomes across the life course. In such studies, selective mortality leads to changes in the social composition of the sample, but little is known about how selective survey part... see more

Using mixed-mode data collection is becoming a mainstream way of conducting longitudinal surveys. However, interviewing the same units in a mixed-mode longitudinal design can lead to respondents switching between modes over time. As a result, mode switchi... see more

In an opening paper Harvey Goldstein questions the need for observational studies to achieve representativeness for real populations, in particular for longitudinal studies. He draws upon recent debates and argues for the need to distinguish scientific in... see more

Longitudinal surveys typically devote considerable resources to tracking procedures designed to minimise attrition through failure to locate sample member who move. Although these tracking procedures are often very successful, there is relatively little m... see more

In many panel surveys that rely on face-to-face interviewing, interviewers are repeatedly allocated to the same respondents in each wave. Researchers and fieldwork agencies argue that interviewer continuity can contribute to the quality of the data collec... see more

Refusal conversion is one of the fieldwork strategies commonly used to minimise non-response in surveys. There is, however, relatively little evidence about the effectiveness of this strategy, particularly for face-to-face longitudinal surveys. Moreover, ... see more
