Four experiments examined the hypothesis that individuals who hold discrepant implicit and explicit self-esteem possess relatively strong self-image concerns. As a result, they may act irrationally when expressing sexual health attitudes. In support of the hypothesis, Experiments 1a and 1b demonstrate that large self-esteem discrepancy participants possess strong implicit self-image ambivalence relative to small self-esteem discrepancy participants. In Experiments 2 and 3, participants who varied in self-esteem discrepancies received either negative or positive (or no) feedback on an intelligence test, and then they were given an opportunity to express implicit and explicit attitudes toward condoms. Large self-esteem discrepancy participants who received a self-threat responded irrationally and expressed relatively strong negative implicit (but not explicit) attitudes toward condoms. However, this detrimental effect was completely reversed following a self-affirmation to large discrepancy participants. The implicit and explicit attitudes toward condoms of small discrepancy participants were unaffected by a self-threat or a self-affirmation.
