Facebook commerce, a new and novel form of social commerce that has gained momentum over the last few years, refers to the utilization of the largest social networking site in the world, Facebook, to buy, sell, and exchange products and services. Both individual consumers and businesses are using the platform to conduct electronic business activities. Drawing on the extant literature on perceived social support, need for cognitive closure, and social commerce, a multidisciplinary conceptual model was advised to investigate the direct and indirect impacts of the need for cognitive closure as an individual trait on Facebook members’ intention to use the platform for e-commerce activities. An online survey was used to gather data from Facebook users in Jordan. The findings indicate that both shoppers’ perception of social support and need for cognitive closure display direct positive impacts on Facebook commerce intention. Moreover, the results show that need for cognitive closure positively influences one’s perception of social support over Facebook which in turn increases purchase intention, supporting the proposed hypothesis that perceived social support mediates the relationship between need for cognitive closure and Facebook commerce intention. Theoretical and managerial implications of the study along with limitations, future research directions and conclusions are discussed in the paper.
