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.

Three, nine-point items are used to measure the degree to which a person believes that a sensory experience with a product from a category would provide him/her with a better understanding of the different types within the category.  To be clear, this scale focuses on the differences between product types across a category (breadth) rather than the similarity within one type of product (depth).
