“…Early research underscores the importance of source credibility in determining responses towards information sources (Hovland et al, 1953). More recent studies in various contexts have also accentuated the significant effects of source trustworthiness on various consumer outcomes such as attitudes towards a message, information adoption and purchase intentions (e.g., Ayeh, Au, & Law, 2013b;Jin, Cheung, Lee, & Chen, 2009;Kim & Kim, 2013;Li, 2013;MacKenzie & Lutz, 1989;Pornpitakpan, 2004;Sussman & Siegal, 2003;Wang & Doong, 2010).
