I have relied on the Marketing Scales Handbooks over several years in academic and industry roles and look forward to using the newest edition. A seven on a seven-point satisfaction scale!
Materialism (Adolescent)
The degree to which a person believes that happiness is derived from buying and owning things is measured in this scale with ten, four point items. The scale is intended for use with teens or even pre-teens and was called the Youth Materialism Scale by its developers (Goldberg et al. 2003)
