Abstract: | Self‐esteem has been found to be related to the certainty with which specific self‐conceptions are held. This study tested a number of competing accounts for this relationship, using a more rigorous idiographic approach. Specifically, it was thought that the relationship between self‐esteem and self‐certainty might be mediated by self‐concept clarity, the positivity of specific self‐conceptions, and impression management concerns. However, none of these fully mediated the relationship between self‐esteem and self‐certainty. Participants with higher self‐esteem were more certain of their central self‐conceptions than were those with lower self‐esteem. This was true even though participants were allowed to generate their most relevant and central self‐conceptions themselves. Discussion focuses on the role of social information in the possibly direct relationship between self‐esteem and self‐certainty. Copyright © 2003 John Wiley & Sons, Ltd. |
