Professional respondents in panels

Single Wave Study

General Information

Professional respondents in panels
This questionnaire will be used to investigate the existence of different respondent types in the LISS-I panel. It will be examined whether these respondent types differ on demographic and psychographic variables and survey attitudes, whether respondent types differ in response propensity and attrition in the LISS-I panel and if they produce data of different quality. The questionnaire is also administered to the LISS panel.
