This scale measures how much a consumer prefers products and experiences that align with their true self and personal values. It is the personal-authenticity dimension of Bartsch, Zeugner-Roth, and Katsikeas's (2022) consumer authenticity seeking (CAS) framework, validated across six studies.

Reliability was consistently good to excellent across four administrations (α = .84, .87, .86, .92; Bartsch, Zeugner-Roth, and Katsikeas 2022, p. 300). Two-week test-retest reliability was r = .66 (Study 4, n = 54). The scale showed strong content, convergent, discriminant, predictive, nomological, and known-group validity, with AVEs of .64-.73 in Studies 2, 5, and 6.
