RT Journal Article SR Electronic T1 #BeingReal about Instagram Ad Models: The Effects of Perceived Authenticity JF Journal of Advertising Research JO J Advert Res FD WARC SP JAR-2019-035 DO 10.2501/JAR-2019-035 A1 Heather Shoenberger A1 Eunjin (Anna) Kim A1 Erika K. Johnson YR 2019 UL http://www.journalofadvertisingresearch.com/content/early/2019/09/26/JAR-2019-035.abstract AB This research suggests that perceived authenticity plays a significant mediating role for the effects of model image modification and body size on consumers' advertisement and product evaluations. Participants reported that they liked the advertisement more—and more likely would buy the advertised items in advertisements—with a not digitally enhanced plus-sized female model, because of the perceived authenticity of the model. The results of this investigation also suggest that attitude toward the advertisement and purchase intention were highest when a plus-size model who was not digitally enhanced was featured on a women's clothing brand's Instagram account.
