This three-item scale measures how far a person believes a particular product is artificial rather than natural and contains additives. Philipp-Muller, Costello, and Reczek (2023) used it in two MTurk studies, with smoothies and body wash as the focal products, in research on when invoking science in product marketing backfires. The authors implied that Rozin (2005) and Scott and Rozin (2017) were the source; those articles discuss naturalness and additives but contain no comparable multi-item scale, so the items appear to have been written by the authors drawing on that work.
7-point scale (1 = not at all, 7 = very much so)
Full scale items shown. Always cite the original source when using this scale in research.
Alphas were .89 (Study 2, n = 402) and .86 (Study 3B, n = 1,013) (Philipp-Muller, Costello, and Reczek 2023, pp. 727, 730); validity was not discussed. Item 2 is reverse-scored. The blanks are filled with the name of the focal product. Rozin (2005) and Scott and Rozin (2017) are best regarded as inspiration rather than the origin of the items. See also Naturalness of the Object (ID 90457), Naturalness of the Food (ID 90044), and Perceived Device Artificiality (ID 90221).
