Promoting healthy eating by enhancing the correspondence between attitudes and behavioral intentions

Background: Healthy eating campaigns are not always successful in changing food-related attitudes. Even when interventions produce the desired outcomes in attitudes, it is often challenging to translate those psychological changes into subsequent behaviors. Previous research has shown that elaboration (amount of thinking) is a critical construct for understanding the ability of attitudes to guide behavior. Instead of looking directly at objective elaboration, this study examined attitude-behavior correspondence as a function of subjective elaboration. Method: Participants were first randomly assigned to generate positive or negative arguments with regard to taxing junk food. After this experimental manipulation, participants reported their subjective elaboration (as an additional predictor), and their attitudes and behavioral intentions regarding the proposal (as dependent measures). Results: As hypothesized, the results showed that the greater perceived elaboration, the larger the ability of attitudes to guide behavioral intentions. That is, attitudes were more predictive of behavioral intentions in participants with higher levels of perceived elaboration compared to those with relatively lower levels of subjective thinking. Conclusion: Health initiatives can benefit from considering the extent to which participants perceive thinking about persuasive proposals.
