Acar et al. (2021) adapted this scale from a measure used by Kirmani et al. (2017); used with a Prolific sample. Reliability was good (α = .90). Validity wasn't discussed. This is a companion to three other scales from the same paper already on this site (Product Preference ×2, Purchase Motivation).
