The role of usability, aesthetics, usefulness and primary task support in predicting the perceived credibility of academic social networking sites

With technology being ubiquitous in our daily lives, it is crucial to understand the factors that influence their perceived credibility. In the current research, we focus on the design of Academic Social Networking Sites (ASNSs). In order to facilitate continuous adoption and use of ASNSs, it is important to understand the factors that determine their Perceived Credibility. Using the Persuasive System Design (PSD) framework as a foundation, the study investigated which of these four key constructs (i.e. Perceived Aesthetics, Perceived Usability, Perceived Usefulness and Perceived Primary Task Support) are the most relevant determinants of the Perceived Credibility of ASNSs. In an online survey, the current research assessed this research model. The results of Partial Least Square analyses confirmed that Perceived Aesthetics, Perceived Usefulness and Perceived Primary Task Support are determinants of Perceived Credibility but provided no evidence for Perceived Usability as a determinant. Moreover, the results showed that Perceived Primary Task Support was the most relevant determinant of Perceived Credibility. Implications of these findings are discussed.
