Abstract Interactivity is an often mentioned but seldom operationalized concept associated with the World Wide Web. Interactivity has been positioned conceptually as a process, a function, and a perception, but most operational definitions have focused on the process or function. This study develops scales to operationalize the perception-based approach to interactivity, because consumer perceptions are central to advertising research. Three overlapping constructs that are central to interactivity are explored: direction of communication, user control, and time. A multistage method is used to identify and refine measures of perceived interactivity (MPI). The 18 items included in the MPI offer researchers a tool for measuring a consumer perception central to advertising on the Web.
