AIMS Rather than using the traditional, costly method of personal interviews in a general population sample, substance-use prevalence rates can be derived more conveniently from data collected among members of an online access panel. To examine the utility of this method, we compared the outcomes of an online survey with those obtained with the computer-assisted personal interviews (CAPI) metho...

From a statistical viewpoint, a panel survey has the definite advantage that it offers more accurate estimates of changes than would repeated cross—sectional surveys with the sample size (Cochran, 1977, p.345). For example, suppose one wishes to monitor changes in bus use that may follow an introduction of a new line, and a sample of 1,000 households is drawn for a survey prior to the introduct...

1 Summary Although similar to weighting for unit nonresponse in cross-sectional surveys, adjustment for panel non-response needs to incorporate information about nonrespondents collected in the early waves of the panel. We review different weighting adjustments for panel nonresponse and discuss methods for incorporating complex survey design variables into the weighting adjustments. We propose ...

This article evaluates the effect of the choice of survey recruitment mode on the value of water quality in lakes, rivers, and streams. Four different modes are compared: bringing respondents to one central location after phone recruitment, mall intercepts in two states, national phone-mail survey, and an Internet survey with a national, probability-based panel. The modes differ in terms of the...

The aim of this paper is to explore the relationship between wages, human capital and investment in financial assets with risky returns at the individual level. To explore this relationship from an international perspective, we analyse individual level data from the British Household Panel Survey, the German Socio-Economic Panel and the U.S. Panel Study of Income Dynamics. Our findings suggest ...

Approaches to the use of the International Labour Office U/C Classification of radiological appearances are considered in the context of multiple readers recording different degrees of abnormality. The Panel on Survey Radiology has been set up to provide a basis for standardization. An example of how the panel may be used in this role is given. The approach will depend on the standards maintain...
