Testing a Brief Web-based Intervention to Increase Recognition of Tobacco Constituents
Objective: We examined website formats to increase smokers' recognition of harmful and potentially harmful constituents (HPHCs) in cigarettes. Methods: Adult, daily smokers (N = 279) were randomized to view a brief, single-page study website showing HPHC names and uses. The intervention site was tailored + interactive, labeled by cigarette brand/subbrand showing color imagery and pop-up boxes; the generic + static website (control) was unbranded in greyscale. Eye tracking equipment measured attention (dwell time) to precise website features. Linear regression analyses compared attention to HPHC descriptions and the correct recognition of 15 HPHC chemicals. A randomly selected sub-sample (N = 30) of participants qualitatively rated website usability. Results: Despite spending less dwell time on the HPHC text and entire website, adult smokers who viewed the generic + static website had greater improvement in HPHC recognition compared to the tailored + interactive website (4.6 vs 3.6; p = .02); this finding contrasts with current literature on tailoring and interactivity. Both websites were rated highly on ease-of-use and readability. Conclusions: Basic formats and narrative HPHC Web-based content attracted less visual attention, yet increased recognition of these chemicals in cigarettes, compared to brand-tailored, interactive web-based content.
