Supplementary materials to: Emotional impact of graphic health warnings on tobacco packaging: Analysis of their content

The use of graphic health warnings (GHWs) on tobacco packaging is one of the most widely used public health strategies worldwide, but there is little evidence of the emotional impact of its content and craving they generate. The objective of the present study was to evaluate the emotional and craving responses to GHW content. The study included 300 men and women of different ages (adolescents, young adults, and adults), both smokers and non-smokers. We evaluated the participants’ emotional and craving responses to 16 GHWs with different content (i.e., cancer, cardiovascular disease, abortion, and childhood illness). We analyzed the effects of sex, smoking status, and age. GHWs exhibited the capacity to elicit aversive emotional states, with low levels of arousal and high levels of dominance and did not produce craving. GHWs that showed images of cancer and abortion had the greatest emotional impact. Non-smoking adolescent females experienced the greatest emotional impact of GHWs. The results suggest that GHWs effectively reduce the attractiveness of cigarette packages and discourage consumption, and increasing the size of GHWs may favor avoidance of the package. GHWs that depicted explicit threats had a greater emotional impact, especially in women.
