Testimonial

This scales book is a classic in psychometrics. It is instrumental for survey researchers in the fields of advertising, marketing, consumer psychology, and other related fields that rely largely on attitudinal measures. My copy has gotten me through years of field research by helping provide testable, reliable scales.

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).
