PURPOSE: The role of the charity sport event on health promotion has been radically significant. In addition, cause-related marketing (CRM) is one of the most prominent strategies for event organizers to maintain the financial stability of the organization. Although many literatures focus on the business side of CRM, there is a lack of theoretical models that explains the association between CRM predictors and health campaign outcomes considering health behavior. Considering the importance of corporate sponsorship of philanthropic sport events, it is necessary to investigate how a health campaign in the sport event have an impact on stakeholders, especially those who participate in the event. Thus, the purpose of this study is to examine how the campaign is associated with the participant’s health belief and ultimately change their health-promoting behavior using an extended model of CRM campaign. METHODS: The structural equation modeling (SEM) was used to investigate the direct/indirect effects of the campaign on sponsor image and breast cancer test. This study was conducted with 1,000 females (18-56) who participated in the Pink Ribbon Marathon. RESULTS: The overall structural model’s goodness of fit showed excellent (χ2 = 15489.377, p<.01; RMSEA = .049, 90% CI =.046-.052; SRMR =.075; TLI =.910; and CFI =.918). SEM revealed that the following factors of Sponsor Fit (β = .736, p <.01). However, sponsor image, product reputation, and CSR were found to have no significant association with the campaign impact. Also, the findings of the results indicated that the impact of the campaign was found to have statistical significance with Perceived Barriers (β = .151), Perceived Threat (β = .-0.168), Self-Efficacy (β =.405), and Cues to Action (β =.650). All four factors regarding health belief positively influence on the intention to participate in breast cancer test. CONCLUSIONS: The results show that the pink ribbon campaign led to a higher level of the intention for breast cancer test by mediating participants’ existing health beliefs. Also, the effect of the campaign was expanded to creating a positive sponsor image. The findings provide insights into designing their cause-related marketing initiatives for practitioners. More detailed explanations concerning theoretical and practical implications will be presented.
