Abstract: A between-subjects 2 (source type: celebrity versus non-celebrity) x 2 (message valence: positive versus negative) factorial experiment (N = 288) examined the effects of source type and message valence on various outcomes of Instagram-based advertising messages about veganism. Results of data analyses indicate significant main effects of message valence on perceived information value of pro-veganism posts on Instagram and significant interaction effects of the two manipulated factors on consumers’ intention to spread electronic word-of-mouth (eWOM) about pro-veganism. Furthermore, perceived prosocial characteristics of the pro-vegan source and intention to build an online friendship with the source significantly moderated the effects of endorser type and message valence on perceived information value and eWOM intention. Theoretical contributions and practical implications are discussed.
Abstract: With an estimated 10.8 million adult users, particularly amongst 18 to 24-year olds, e-cigarette use is an increasingly serious health issue within the United States. These products are often promoted as smoking cessation devices for use in quitting smoking and nicotine replacement therapy. JUUL, a leading brand of e-cigarettes, is also heavily featured in online social media posts. This content analysis examined posts related to JUUL on the Instagram for their product relevance, how they are promoted, and how they are featured. Descriptive analysis and unsupervised topic modeling were used in preparation for future analysis involving additional relevance coding to analyze for links between content features and topic modeling results. Preliminary results reveal our TM topics and terms for analysis, a lack of promotion of JUULs as smoking cessation/NRT devices by commercial interests, and that half of JUUL-related posts were not JUUL relevant, suggesting its use to promote unrelated posts.
Abstract: This study examined effects of hashtag type (brand name versus empowering campaign hashtag) on information value and attitude towards hashtags. Results indicated that consumers showed more favorable attitudes towards empowering campaign hashtags than brand name hashtags, and that perceived information value of hashtags meditated the relationship between hashtag type and attitude toward the hashtags. Furthermore, consumer responses to the two hashtag types varied across luxury and mass-market cosmetic brands. When cosmetic brands used brand name hashtags, consumer responses were comparable across both brand types, but when brands used empowering campaign hashtags, perceived luxury affected consumer responses.
Abstract: Through a 2×3 between-subjects experiment, this study examined effects of health warning labels (presence or absence) and advertising message claims (“Quit smoking using e-cigarettes,” “Healthier than regular cigarettes” or none) in celebrity-endorsed Instagram e-cigarette brand advertisements. Results indicated health warning labels exerted significant main effects on attitude towards e-cigarettes, intention to use e-cigarettes, and brand attitude, and interacted with message claim type to affect these dependent measures. Health consciousness, perceived information value and social media usage also significantly moderated between health warning labels and attitude towards e-cigarettes, intention to use e-cigarettes and brand attitude. Research and practical implications are discussed.
