Such work may be challenging in countries where policies have strongly denormalised smoking and arguably created disincentives for smokers to self-identify.12 17 Translating the messages sellckchem we found effective into interventions would enable the examination of cessation-linked responses among women and those in their immediate social network.16 20 A quantitative study estimating how women of childbearing age who smoke respond to the messages our participants regarded as most effective could examine how our findings predict population-level responses. Such a study could

estimate how likely respondents are to quit before becoming pregnant, or on learning they are pregnant, and would provide direct guidance to policymakers. While these studies could not determine causality, they would nevertheless enable comparison of the messages’ relative effects. Future work could also explore how effectively the messages tested maintain smoke-free behaviour, particularly postpartum, when relapse is common.6 20 35 Conclusions Knowledge of the metaphors on which smokers rely and the rationalisations these

support informed new message strategies, the most effective of which focused on affect rather than cognitions. Specifically, framing smoking not as an assertion of women’s choices, but as a behaviour that deprives children of the freedom to make choices, offers a new approach to promoting cessation to pregnant women. In line with conceptual and empirical studies foregrounding the primacy of affective responses, messages that aroused strong self-referent emotions created dissonance less amenable to counter-argument. Generating affective, rather than cognitive, dissonance appears to have a stronger cut-through than

informational or didactic messages. Our findings have two key implications. First, they suggest policymakers could diversify their current approaches to behaviour change, which assume a rational decision-making process in which few consumers engage. Second, our results offer social marketers a potentially more effective new approach to designing interventions for this high priority population group. Specifically, we suggest there is potential value in testing the most effective messages in targeted communications that reach women when they are in healthcare settings where cessation support is available.
