Social Allure Ads

Active Comparator group

Description:

Described below is Phase 3. Phase 1 and Phase 2 were small pilots used to inform and select study stimuli. Phase 3 was the larger randomized controlled online trial testing effects of warnings on social allure ads.. Participants were randomized to one of three health warning label (HWL) arms in a 1:2:2 ratio: 1) ads only, 2) ads with text HWLs only, and 3) ads with text + graphic HWLs. Within the latter two groups, participants were then randomized with equal probability to view HWLs in one of four domains: long- and short-term health events, toxicants, and addiction; participants viewed two HWLs within each domain - there were two HWLs per domain. The text or text + graphic HWLs were placed randomly on two social allure ad themes without replacement. Thus, participants viewed two HWLs within the same domain, with each warning being placed on a different social allure ad. Participants in the ads only arm, only viewed two ads without replacement.

Product Ads

Active Comparator group

Description:

Described below is Phase 3. Phase 1 and Phase 2 were small pilots used to inform and select study stimuli. Phase 3 was the larger randomized controlled online trial testing effects of warnings of product ads. Participants were first randomized to one of three health warning label (HWL) arms in a 1:2:2 ratio: 1) ads only, 2) ads with text HWLs only, and 3) ads with text + graphic HWLs. Within the latter two groups, participants were then randomized with equal probability to view HWLs in one of four domains: long- and short-term health events, toxicants, and addiction; participants viewed two HWLs within each domain - there were two HWLs per domain. The text or text + graphic HWLs were placed randomly on two ads that represented a flavored tobacco product or a waterpipe apparatus. Thus, participants viewed two HWLs within the same domain, with each warning being placed on a product ad Participants in the ads only arm, only viewed two product ads without replacement.
