Five items assess whether a consumer perceives two products that are jointly promoted as genuinely related — that is, as items typically used or consumed together. Aydınoğlu and Krishna (2019) employed the scale as a manipulation check across pretests in four studies. The scale appears to have been created by the authors. Slightly different versions were used depending on the study: the Study 1 pretest used items 1–3, while later pretests used items 2–5.
