RT Journal Article SR Electronic T1 Endorsement Theory: How Consumers Relate to Celebrity Models JF Journal of Advertising Research JO J Advert Res FD WARC SP 564 OP 572 DO 10.2501/S0021849908080550 VO 48 IS 4 A1 Roger Marshall A1 Woonbong Na A1 Gabriel State A1 Sonali Deuskar YR 2008 UL http://www.journalofadvertisingresearch.com/content/48/4/564.abstract AB The relationship of image congruity and postpurchase dissonance has been reported in the advertising literature. The relationship among dissonance, dissatisfaction, and repeat-purchase behavior is a familiar subject as well. But the juxtaposition of all three constructs has yet to be fully explored. In this research, the incongruity between self-image and the image projected by an advertisement is found to correlate to postpurchase dissonance in the purchasers of lipstick. A follow-up study tracks satisfaction and repeat purchase intentions, and through structural equation modeling, it is established that although satisfaction is not related directly to dissonance, repeat purchase is dependent upon both satisfaction and dissonance.
