Self-affirmation theory and cigarette smoking warning images

Introduction: The present study examined self-affirmation theory, cigarette smoking, and health-related images depicting adverse effects of smoking. Previous research examining self-affirmation and negative health-related images has shown that individuals who engage in a self-affirmation activity are more receptive to messages when compared to those who do not affirm. We were interested in examining the extent to which self-affirmation would reduce defensive responding to negative health images related to cigarette smoking. Methods: Participants included 203 daily smokers who were undergraduate students at a large southern university. Participants completed a battery of questionnaires and were then randomly assigned to one of four conditions (non-smoking image control, smoking image control, low affirmation, and high affirmation). Analyses evaluated the effectiveness of affirmation condition as it related to defensive responding. Results: Results indicated that both affirmation conditions were effective in reducing defensive responding for those at greatest risk (heavier smokers) and those more resistant to health benefits associated with quitting. Conclusions: Findings are discussed in terms of potential public health implications as well as the role defensive responding plays in the evaluation and processing of negative health messages.
