• Nowadays celebrity endorsement has become a popular marketing technique in the non-profit sector. However, there is still a degree of light and shade as regards the determinants of the effectiveness of this communication strategy. Taking into account the significant lack of studies in this particular field, the current research presents a causal model with nine hypotheses, which analyse the sequence of relationships that cover from the background of celebrity credibility, to the determinants of the attitude towards adverts and the intention to collaborate. We surveyed 329 adults, who rated a fictitious ad with a celebrity without perceived experience in the non-profit area. As a result, it is observed that the celebrity�s credibility depends on the fit perceived, the attribution of altruistic motivation, the celebrity image and the general attitude towards celebrity activism. Furthermore, it is found that a credible celebrity has a strong influence on the attitude towards the advert and, indirectly, on behavioural intentions.
