- Panel Conditioning Effects

Internet panels derived from probability-based sampling are attractive to researchers confronting the limitations of using more traditional modes, such as RDD telephone, to obtain nationally representative estimates (particularly of youth).  However, panel conditioning and panel attrition are potential weaknesses that can compromise panel data quality.  FMG examines panel conditioning effects in a cross-sectional advertising tracking study that involved the reuse of panelists in order to obtain the desired sample sizes.  Data analysis examines group differences in responses to questions on advertising awareness, brand imagery, and product endorsement. Data quality will also be examined by looking at non-differentiation, a form of survey satisficing, and constructing tests of concurrent validity. FMG's conclusions will offer new insights regarding the boundaries of panel conditioning and provide practical recommendations to researchers who employ Internet-panels for their own efforts.  FMG will present this paper (and others) at the 65th Annual Conference of the Association for Public Opinion Research in Chicago, IL.
