How to capture Doppelganger Brand Image with Brand Concept Mapping

In a Web 2.0 context, negative user-generated content (UGC) that damages the brand reputation can be easily produced and quickly spread. There is a lack of literature on how to measure the value destruction, known as doppelgänger brand image (DBI). The authors define DBI as the appearance, or reinforcement, of negative associations at the brand reputation level. Brand reputation is the collective brand image that is shared by multiple stakeholders.
Using brand concept mapping (BCM) on two corporate brands, this study shows the effect of exposure to negative UGC on the brand image perception and measures the impact of this exposure on DBI. The authors use a two*two between-subjects design with 280 consumers in order to study the effects of the type of media and source credibility, brand experience and Internet experience on the DBI.
The results suggest that, the negative UGC will cause an increase in the frequency of mentions of negative associations. At the reputation level, if the brand already has a DBI, an exposure to negative UGC will reinforce it. However, if the brand reputation is mostly positive, a single exposure to negative UGC will not create a DBI.
The results also confirm the effect of source credibility and type of media on the likelihood of DBI. The experience with the brand and with Internet will reduce the risk of DBI.
