What affects the effectiveness of celebrity endorsement? Impact of interplay among congruence, identification, and attribution

ABSTRACT

This study draws upon congruence theory, identification theory, and attribution theory as a means of examining how celebrity endorsement works. The study proposes that the effectiveness of celebrity endorsement may be influenced by the following three factors: congruence between a celebrity endorser and endorsed brand/product, identification with a celebrity endorser, and consumers’ attribution styles (i.e., internal vs. external). To test the proposed hypotheses, the study employs a 2 × 2 × 2 between-subject factorial design. A total of 317 college students participated in the study in return for course credits. The study findings suggest that congruence, identification, and consumers’ attribution styles indeed have impacts on consumers’ attitude toward ad, brand, or purchase intention. The study also finds that there is a relationship between congruence (low vs. high congruence) and attribution styles (internal vs. external). Theoretical and practical implications are discussed.
