Survey mode effects on the general public’s elicited health care preferences

The use of internet surveys to collect information about people’s preferences for health and health care is increasing. However, little is known about how internet surveys differ from other survey modes, such as in-person interviews or postal surveys, in terms of sample representativeness, data quality or the convergent validity of elicited preferences. We present results from the first study to compare internet, in-person and mail surveys when eliciting general population preferences for health care. Each mode has over 1000 respondents. We find that the elicited willingness to pay estimates differ across modes. We also find that the survey mode affects response rates, who responds to a survey, how respondents answer the survey questions and respondents’ ability to provide accurate responses.
Learning objectives:
- The effect of survey mode on the type of people who respond to health related surveys
- The effect of survey mode on preference elicited in surveys
- The effect of survey mode on data quality
