This paper presents a literature review of content validity, summarizes qualitative and quantitative approaches for content validity assessment, and explores the extent to which IS researchers have content validated their developed instruments. An extensive review of scale development papers published in five major IS journals between 1989-2005 revealed that the proportion of published studies reporting content validity had indeed increased; however, qualitative assessment of content validity remains the preferred approach. To encourage the utilization of an alternative approach to content validity assessment, this paper describes a quantitative approach to evaluating the content validity of the B2E portal user satisfaction instrument.
