Moderating effects of self-image congruity on the relationship between advertisement message strength and revisiting intention

This research note delineates the effect of restaurant customers’ perceived self-image congruity (i.e., the match between the image of a product or brand and customers’ image of themselves) on the relationship between the strength of a restaurant advertisement and customers’ intention to revisit that restaurant. This study posits that customers’ preference for a restaurant brand, formed by their perceived self-image congruity, can alter the effects of ad message strength on their revisiting intention. More specifically, due to the biasing effect caused by self-image congruity, the effect of an ad’s argument strength on behavioral intentions may be diminished when customers have a high perceived level of self-image congruity. The findings indicate that strong ad messages elicit significantly higher revisiting intentions than weak ad messages when customers perceive a mismatch between the image, the brand, and themselves; however, no significant difference in revisiting intentions was detected between strong and weak ad messages when customers perceived a match between image and restaurant brand. Furthermore, this study examines how gender-based information-processing tendencies influence this effect of self-image congruity on the relationship between ad message strength and revisiting intention. Overall, this study provides a theoretical understanding of the biasing effect of self-image congruity on customers’ information processing and has important managerial implications for restaurant marketing.
