^aEach expert’s rating was first dichotomized at the item level to indicate the status of an item-specific violation. Guidelines that included ≥ 8 experts who identified a violation were coded as a violation determined by the expert sample.

^bThe frequency criterion is an aggregate method at the item level that requires that > 50% of the experts rate the advertisement in violation.

^cThe average criterion is an aggregate method at the item level that determines whether average ratings of the expert group exceed a predetermined cutoff based on the particular measurement scale.
