Measuring self-disclosure online: Blurring and non-response to sensitive items in Web-based surveys


Joinson, A; Paine, C; Buchanan, T; Reips, Ulf-Dietrich (2008). Measuring self-disclosure online: Blurring and non-response to sensitive items in Web-based surveys. Computers in Human Behavior, 24(5):2158-2171.

Abstract

People are increasingly required to disclose personal information to computer- and Internet-based systems in order to register, identify themselves or simply for the system to work as designed.
In the present paper, we outline two different methods to easily measure people’s behavioral self-disclosure to web-based forms. The first, the use of an ‘I prefer not to say’ option to sensitive questions is shown to be responsive to the manipulation of level of privacy concern by increasing the salience of privacy issues, and to experimental manipulations of privacy. The second, blurring or increased ambiguity was used primarily by males in response to an income question in a high privacy condi-
tion. Implications for the study of self-disclosure in human–computer interaction

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
