How self-affirmation reduces defensive processing of threatening health information: evidence at the implicit level

Health Psychol. 2009 Sep;28(5):563-8. doi: 10.1037/a0015610.

Abstract

Objective: Self-affirmation reduces defensive responses to threatening health information, but little is known about the cognitive processes instigated by self-affirmation. This study tested whether self-affirmation increases responsiveness to threatening health information at the implicit level.

Design: In an experimental study (N = 84), the authors presented high- (coffee drinkers) and low-relevance (noncoffee drinkers) participants with threatening health information linking caffeine consumption to health problems. Prior to reading this information, the authors manipulated self-affirmation.

Main outcome measures: Participants completed an unobtrusive lexical decision task to measure the accessibility of threat-related cognitions and reported their perceptions of message quality and intentions to take precautions.

Results: Among high-relevance participants, self-affirmation increased the accessibility of threat-related cognitions, increased perceptions of message quality, and promoted adaptive behavioral intentions.

Conclusion: The findings suggest that self-affirmation can increase implicit responsiveness to threatening health information among a target audience, that is, people for whom the health information is highly relevant.
