Confirmatory factor analysis test (LISREL) and Cronbach alpha were used to assess the validity of the questionnaire. Results showed the validity and reliability of the questionnaires. The results of the LISREL structural equation show that brand equity is viewed as a mediator in the relationship between viral marketing and behavioral intentions.
