Title Mode and Context Effects in Measuring Household Assets
Year 2011
Access date 21.09.2009

Differences in answers to Internet and traditional surveys can be due to selection, mode, or context and question wording effects. We exploit unique experimental data to analyze mode and context effects controlling for arbitrary selection. The longitudinal Health and Retirement Study (HRS) surveys a random sample of the US 50+ population, with CAPI or CATI core interviews for the same respondents once every two years. In 2003 and 2005, random samples were drawn from HRS respondents in 2002 and 2004 willing and able to participate in an Internet interview. Comparing regular and Internet survey answers of the same people, we analyze mode, context and wording effects, controlling for selection. We focus on household assets, for which mode effects in Internet surveys have rarely been studied. We find some large differences between the first Internet survey and the other three surveys. Further analysis suggests that these differences are the result of context and question wording effects rather than of a pure mode effect.
