Alavi et al. (2020) appear to have created this scale themselves, drawing conceptual inspiration from Zeithaml, Parasuraman, and Berry's (1985) influential framework distinguishing goods from services. Reliability was strong (α = .90–.93) across two MTurk studies. Validity wasn't explicitly discussed, though AVEs of .75–.83 were reported.
