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.

The scale is composed of four, seven-point Likert-type items that measure a consumer's perceived knowledge of brands in a specified product category as well as the confidence to make purchase decisions and give advice to others about the product class.

Seven, five-point, Likert-type statements are used to measure the degree to which a person expresses the need to have friends' approval of where and what he/she buys. The scale was developed for use with teenagers but appears to be amenable for use with other age groups, though some testing may be necessary.
