Purchase Dissimilarity

A consumer's belief that his/her purchase of a product was not the same as experienced by a friend is measured with three, nine-point Likert-type items.  To be clear, the scale measures the belief that the purchases made by two people of the same type of product were different in some way (unspecified) rather than the products themselves being different, e.g., different prices.
