The Psychology of Self‐defense: Self‐Affirmation Theory

This chapter provides an overview of self-affirmation theory. Self-affirmation theory asserts that the overall goal of the self-system is to protect an image of its self-integrity, of its moral and adaptive adequacy. When this image of self-integrity is threatened, people respond in such a way as to restore self-worth. The chapter illustrates how self-affirmation affects not only people's cognitive responses to threatening information and events, but also their physiological adaptations and actual behavior. It examines the ways in which self-affirmations reduce threats to the self at the collective level, such as when people confront threatening information about their groups. It reviews factors that qualify or limit the effectiveness of self-affirmations, including situations where affirmations backfire, and lead to greater defensiveness and discrimination. The chapter discusses the connection of self-affirmations theory to other motivational theories of self-defense and reviews relevant theoretical and empirical advances. It concludes with a discussion of the implications of self-affirmations theory for interpersonal relationships and coping.
