While past research has revealed diverse forms of relationships between consumers and brands similar to those of interpersonal relationships, this research focuses on the perspective of the brand role in its relationship with consumer in an advertising context. Therefore, the present research examines the interactive effect of brand role (partner vs. servant) and regulatory focus message (promotion vs. prevention) on advertising effectiveness. The results show that interaction between brand role and regulatory focus message significantly influences advertising persuasiveness and consumers' attitudes toward the advertisement, but not consumer's advertising believability, attitudes toward the brand and purchase intention. To be specific, individuals are more persuaded and show more positive attitudes toward advertising when a partner brand is advertised with a promotion-focused message. In contrast, when a servant brand is advertised with a prevention-focused message, individuals are more persuaded and show more positive attitudes toward advertising. / text
