Athlete endorsements are widely used to shape consumer responses, yet how endorsement cues translate into Purchase Intention remains underexplored in integrated models. This study tests the effects of Endorser Credibility, Endorser–Product Fit, Emotional Appeal, and Social Influence on Purchase Intention, with Brand Trust as a mediator. Data were collected through an online survey of 610 respondents in Goa with prior exposure to athlete-endorsed advertising. The model was analysed using PLS-SEM (SmartPLS) with bootstrapping to estimate direct and indirect effects. Emotional Appeal, Endorser Credibility, and Endorser–Product Fit show significant direct effects on Purchase Intention and significant indirect effects via Brand Trust. Social Influence shows a small direct effect on Purchase Intention, but its indirect effect via Brand Trust is not significant. Measurement invariance (MICOM) confirms full invariance across gender, supporting multi-group comparisons. MGA indicates that the effects of Emotional Appeal, Endorser Credibility, and Social Influence on Purchase Intention differ significantly between male and female respondents. IPMA identifies Brand Trust as the most important driver of Purchase Intention but with only moderate performance, indicating that trust-building should be a strategic priority. Overall, the findings suggest that Brand Trust and Emotional Appeal are central mechanisms linking athlete endorsements to Purchase Intention, whereas Social Influence alone has limited capacity to generate trust-based buying motivation in this context.
