Self-Persuasion Increases Healthy Eating Intention Depending on Cultural Background.

Area of Science:

• Behavioral Science
• Health Psychology
• Cross-Cultural Psychology

Background:

• Unhealthy eating is a global health concern requiring effective intervention strategies.
• Self-persuasion shows promise over direct persuasion for attitude and intention change.
• The moderating role of cultural background in persuasion effectiveness for healthy eating remains under-explored.

Purpose of the Study:

• To investigate the effectiveness of self-persuasion versus direct persuasion in promoting healthy eating intentions.
• To examine how cultural background (Dutch, Moroccan-Dutch, Turkish-Dutch) influences the effectiveness of these persuasion techniques.
• To explore potential cultural differences in responses to healthy eating messages in the Netherlands.

Main Methods:

• Two studies were conducted with participants from diverse ethnic backgrounds in the Netherlands.
• Participants were exposed to either a self-persuasion or a direct persuasion message via posters.
• Healthy eating intention for the upcoming month was measured post-exposure.

Main Results:

• Significant cultural differences in healthy eating intentions were observed between ethnic groups.
• Cultural background moderated the relationship between persuasion type and healthy eating intention.
• Self-persuasion was more effective for individuals with an individualistic cultural orientation.
• Direct persuasion was more effective for individuals with a collectivistic cultural orientation.

Conclusions:

• Cultural background significantly moderates the effectiveness of persuasion strategies for promoting healthy eating.
• Tailoring persuasion techniques to cultural values (individualism vs. collectivism) can enhance healthy eating interventions.
• Findings suggest a nuanced approach to health communication, considering cultural specificities for optimal impact.
