This three-item scale measures a consumer's interest in, and likelihood of, buying a specific product they have just been shown. Hoffmann, Joerß, Mai, and Akbar (2022) used it in two follow-up studies with Prolific participants in research on augmented reality-delivered product information at the point of sale. The authors cited Dodds, Monroe, and Grewal (1991), but the overlap is limited to a few key words, so the scale is best regarded as the authors' own, borrowing some terms and ideas from that earlier measure.
Not stated by the authors; likely 7-point Likert-type (strongly disagree / strongly agree)

Alpha was .91 in both Follow-up Study 1 (n = 310) and Follow-up Study 2 (n = 420) (Hoffmann et al. 2022, pp. 759, 760). CFAs in both studies showed very strong loadings and clear unidimensionality, and supported discriminant validity relative to several other scales. The response format was not described; the authors generally used seven-point scales. Named with a qualifier to distinguish it from other purchase intention measures; see also Purchase Intention Scale (ID 208), Purchase Intention Semantic Differentials (ID 890), and Purchase Likelihood (In-Store Product Search) (this batch).
