In contrast to previous studies, which have used \u2018choice overload\u2019 to represent the amount of information provided to consumers, this study used \u2018information overload\u2019 theory to represent the abundance of information received by consumers in online shopping environments. Borrowing from the concepts of the communication model, this study investigated the antecedents of perceived information overload, including information characteristics (message), the information source, the system interface (channel) and recipients\u2019 motivation (receiver). A total of 15 adults with more than 3 years of online shopping experience participated in a focus group discussion. By integrating focus group results and the results of previous studies into a theoretical framework, this study developed and empirically tested a structural equation model of online information overload among 456 PChome customers. The results indicated that the complexity and ambiguity of information characteristics, number of brand alternatives offered by the information source and system interface all positively affect consumers\u2019 perceived information overload. Furthermore, information recipients\u2019 motivation not only negatively affected consumers\u2019 perceived information overload but also moderated the relationship between the number of brand alternatives and consumers\u2019 perceived information overload.<\/jats:p>","DOI":"10.1177\/0165551516670096","type":"journal-article","created":{"date-parts":[[2016,10,13]],"date-time":"2016-10-13T21:55:44Z","timestamp":1476395744000},"page":"835-851","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":72,"title":["Why do online consumers experience information overload?
