Abstract
Methods: The participants of the study were Filipino internet service subscribers, and they were selected using purposive sampling technique. The approach used in this study was quantitative research and causal-predictive approach while the partial least squares-structural equation modeling (PLS-SEM) was used to estimate the relationships of the proposed model.
Findings: The results showed that an endorser's credibility significantly influences consumers’ purchase intention and attitude towards a brand. On the other hand, the relationship between brand credibility and purchase intention is not supported. However, there is a significant relationship between brand credibility and attitude towards a brand. The relationship between attitudes towards a brand and purchase intention is also supported. The mediation analysis revealed the importance of attitude towards a brand which tremendously mediates the relationship between brand credibility and endorser’s credibility leading to purchase intention.
Originality: This study highlights the novel role of consumers' attitude as a mediator between endorser and brand credibility, shaping purchase intentions in the Philippine telecom industry through K-pop idol endorsements.
