This scale measures how unsure a consumer feels about whether they will end up liking a product they just chose. Choe, Kan, and Polman (2023) used it in a study on how budgeting differs for gift purchases versus personal purchases.

Reliability was strong (α = .903; Choe, Kan, and Polman 2023, web appendix, p. 10). The item set was created by the authors, drawing a single keyword per item from an earlier persuasion-and-certainty scale rather than reusing its items directly. In a gift-purchase condition, wording shifts to reference a friend's anticipated reaction rather than the respondent's own. The blank should be filled with a name for the focal product.
