Measures the degree to which a consumer anticipates that a specific product will enhance their performance in a relevant domain. All three items require blanks to be filled with both the product name and the performance domain, making the scale highly flexible across physical, cognitive, and prestige-related contexts. Developed as a manipulation check for research on marketing-induced placebo effects. Two items use bipolar anchors (harm/help; bad/good at improving); one is phrased as a direct extent question.
