The scale measures the likelihood that a consumer will buy a product he/she is knowledgeable of. The measure was referred to as willingness to buy by Dodds, Monroe, and Grewal (1991) as well as Grewal, Monroe, and Krishnan (1998). The version of the scale used by Dodds, Monroe, and Grewal (1991) had five items whereas the ones used by Grewal, Monroe, and Krishnan (1998), Grewal et al.(1998), and Hardesty, Carlson, and Bearden (2002) had three.
I really appreciate your marketing scales database online. It is an important resource for both our students and our researchers as well. Since my copies of the original books are slowly disintegrating due to the intensive use, I am happy that you are making them available in this way. It is very helpful in the search for viable constructs on which to do sound scientific research.
