Abstract
INTRODUCTION: Emotive health messages are widely used tools in tobacco control. However, under some circumstances, they can be less effective than desired by eliciting defensive responses in smokers. AIMS: This study tests whether enhancing a currently used emotive graphic smoking health warning with a self-affirmation component reduces cigarette consumption and whether potential effects are stronger in heavier smokers, as suggested by previous research. METHODS: Participants (n = 265) were randomly allocated to a self-affirmation (reflecting on personal values and positive traits using a questionnaire) or matched control condition before viewing an emotive graphic health message from a current Australian government public health campaign. The primary outcome (cigarettes per day [CPD]) was assessed both before and a week following the intervention. RESULTS: No main effect of self-affirmation on smoking, but as hypothesized, a significant interaction between baseline smoking and self-affirmation was found that showed that heavier smokers (>21 CPD) who self-affirmed significantly reduced CPD compared to nonaffirmed smokers. CONCLUSIONS: These findings support the use of self-affirmation to enhance smoking awareness campaigns in heavier smokers. IMPLICATIONS: This study shows that enhancing emotive graphic smoking health messages with self-affirmation (the act of reflecting on positive aspects of oneself) increases their effectiveness in heavier smokers. This suggests that self-affirmation might be a particularly useful tool for health promotion targeting heavier smokers. This study adds to previous research in that it is the first to test the add-on effects of self-affirmation to current graphic health messages on smoking rather than smoking-related cognitions.
