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.

Expected Picture Quality (Camera)

A three-item, seven-point summated ratings scale measuring the level of picture quality a consumer expects in a particular camera. Expectations are supposed to be distinct from desires because the latter relates to beliefs about ''ideal'' product performance that led to achievement of higher-level values whereas the former are beliefs about performance benefits that will occur with a specified focal brand but may be short of what is ''ideal'' (Spreng and Olshavsky 1993, p. 172). Thus, desires imply a higher standard than do expectations.
