Though perceived value in e-services is construed as a multi-dimensional construct,
the dimensions are contextual and are therefore measured with a single-item scale.
van Riel et al. (2001) measured perceived value by asking respondents there degree of agreement with the statement “For the money, the portal delivers good quality.”
Parasuraman et al. (2002) asked respondents to rate the web site on four statements with implicitly expressed benefits and sacrifices: for example,
“The overall convenience of using this site” and “The overall value you get from this site for your money and effort.
This paper adopts the same view and value in use is measured with a single-item statement.
