Over the last three decades, the public's willingness to takepart in surveys has gradually declined, and the decline hasbeen attributed in part to increasing concern about the confidentialityof the data requested. This paper reviews the early literaturebearing on confidentiality assurances and willingness to respond,and then reports on three experiments designed to investigatethe effects of confidentiality on the expectations of respondentsand on their willingness to take part in a survey. The resultsof all three experiments confirm our expectation that confidentialityassurances are not always perceived as reassuring, and do notnecessarily increase the public's willingness to respond.  相似文献   

'NO OPINION'-FILTERS: A COGNITIVE PERSPECTIVE   总被引：1，自引：0，他引：1

Research on the use of ‘no opinion’-filters suggeststhat respondents are the less likely to offer a substantiveresponse the more strongly the filter question is worded. Aseries of experiments is reported that demonstrates that filterquestions influence respondents' perception of their task: themore strongly the filter question is worded, the more respondentsassume that they will have to answer difficult questions, andthat they may not have the required knowledge. Accordingly,filter questions discourage respondents from offering globalopinions that they may hold. In line with this assumption, allrespondents who reported not having an opinion in response toa filter question, subsequently provided substantive responseson a global opinion question—presumably because the globalquestion asked was less demanding than expected on the basisof the filter. Analyses of these substantive responses indicatedthat respondents who initially reported not having an opiniondiffered from respondents who reported having one. Methodologicalimplications of these findings for the use of filter questionsand for research on the nature of ‘floating’ arediscussed.  相似文献
