OBJECTIVES: >50 countries use graphic health warnings (GHWs) with the minimum size that is recommended by the World Health Organization (WHO). The aim of the present study was to evaluate the effect of the size of GHWs on physiological responses that serve as indices of arousal and aversive motivation in nonsmokers, weekly smokers, and daily smokers. METHODS: The skin conductance response, corrugator muscle activity, and startle reflex were recorded in 35 nonsmokers, 35 weekly smokers, and 35 daily smokers while they observed pictures of cigarette packs without GHWs, cigarette packs with GHWs that covered 30% of the pack, and cigarette packs with GHWs that covered 60% of the pack. RESULTS: Cigarette packs with 30% GHWs did not generate significantly higher responses on any of the physiological measures compared with cigarette packs without GHWs. Conversely, cigarette packs with GHWs that covered 60% of the pack generated a greater skin conductance response, greater corrugator muscle activity, and an increase in the startle reflex compared with cigarette packs without GHWs. No significant differences were found between groups in any of the physiological measures. CONCLUSIONS: The minimum size of GHW that is recommended by the WHO is insufficient to generate an emotional response that favors avoidance of the cigarette pack. GHW that cover 60% of the cigarette pack significantly reduced the attractiveness of the tobacco packaging and generated greater arousal responses.
