Individual differences in spontaneous self-affirmation predict well-being

ABSTRACT The present research examines the relationship between individual differences in the extent to which people report self-affirming when faced with a threat (spontaneous self-affirmation) and well-being. Across three studies (total N = 515), spontaneous self-affirmation consistently emerged as a significant linear predictor of hedonic and eudaimonic well-being outcomes, both cross-sectionally and longitudinally. A self-affirmation manipulation eliminated this association for two indices of well-being, primarily by boosting the well-being scores of those lower in spontaneous self-affirmation. Furthermore, spontaneous self-affirmation was found to partially mediate associations between socioeconomic status and well-being. These findings highlight individual differences in spontaneous self-affirmation as a potentially important contributor to well-being and suggest that consideration of spontaneous self-affirmation might further our understanding of the relationship between socioeconomic status and well-being.
