What was measured

Dwell time measures the total duration of attention to an area of interest (AOI). Each warning label consisted of two AOIs: image AOI and text AOI. Dwell time for each AOI was averaged across three PWLs within each arm.

Analysis population: Sticky's internal algorithms determined cases where the eye tracking data is less than "perfect" and only returns "usable" data. Thus, only usable eye tracking data were analyzed.

Groups in this outcome

Narrative Pictorial Warning Labels

Participants in this arm were presented with three narrative pictorial warning labels (PWLs) for alcoholic beverages. Narrative PWLs included a photo showing the lived experiences of individuals affected by alcohol-related cancer (e.g., a headshot of a man with a misshapen jaw) and a text warning statement (e.g., WARNING: Drinking alcohol can cause oral cancer). The warnings focused on oral, esophageal, and laryngeal cancers, respectively.

Non-Narrative Pictorial Warning Labels

Participants in this arm will be presented with three non-narrative pictorial warning labels (PWLs) for alcoholic beverages. Non-narrative PWLs contained graphic images of diseased organs (e.g., a closeup image of a mouth with rotten teeth and oral thrush) and a text warning statement (e.g., WARNING: Drinking alcohol can cause oral cancer). The warnings focused on oral, esophageal, and laryngeal cancers, respectively.
