Conceptualizing similarities and differences between purpose in life and self-affirmation.

Individuals contend with a variety of threats in daily life and may attempt to deal with them using various cognitive strategies. Two constructs borne from different literatures, purpose in life and self-affirmation, serve to promote well-being and to protect individuals from such threats. While self-affirmation has often been examined as a manipulation, purpose has, until recently, been considered a dispositional resource. However, both self-affirmation and purpose seem to confer similar advantages in response to threat. This paper reviews the evidence for the protective benefits of both purpose in life and self-affirmation, describes the mechanisms by which each confers these advantages, and considers the boundary conditions of each. Key similarities and differences are discussed, and we argue that there are broad gaps in the literature regarding where and when these constructs might operate differentially, or why these differences exist. We conclude with a call to researchers to explore empirically how and when these important interventions might be differentially beneficial to those who cultivate them. [ABSTRACT FROM AUTHOR]
