Celebrity Endorsement for Nonprofit Organizations: The Role of Celebrity Motive Attribution and Spontaneous Judgment of Celebrity-Cause Incongruence

This study investigated relationships among celebrity motive attribution, celebrity-cause congruence, and involvement with a cause. A 2 (altruistic motive: high vs. low) X 2 (congruence: high vs. low) X 2 (involvement: high vs. low) experimental study examined perceptions of celebrity credibility, attitudes toward celebrity endorsement and nonprofit organization, and intentions to donate money and volunteer time. The findings attest to main effects of causal attribution of a celebrity's altruistic motive and interaction effects between motive attribution and congruence (i.e., spontaneous judgment of celebrity-cause incongruence). Further, three-way interaction effects suggest the role of involvement in spontaneously activating celebrity-cause disassociation.
