Product Replacement Motivation
Six statements with seven-point Likert-type response scales are used to measure the degree to which a person has bought a product because what it replaces is viewed as being degraded to the point of unacceptability, probably due to poor performance. At the other extreme, a purchase is indicated to have occurred because something newer was available that was more desirable than what was replaced. The scale was called nature of purchase decision by Grewal, Mehta, and Kardes (2004).
