We predicted that greater self-esteem would predict greater efficacy and esteem support when partners needed support, which would facilitate greater efficacy and self-esteem in partners. We examined these processes within discussions in which one partner could provide support (support provider) to the other (support recipient). Study 1 illustrated that self-esteem was specifically associated with esteem support. Study 2 demonstrated that support providers higher in self-esteem experienced greater efficacy during couples¡¯ support discussions and thus delivered greater esteem support to their partners. Greater esteem support, in turn, was associated with recipients experiencing greater efficacy within couples¡¯ discussions and greater self-esteem across time. Analyses of alternative explanations indicated these processes were unique to self-esteem and esteem support. The results provide initial evidence that self-esteem and efficacy shape, and are shaped by, esteem-related support processes within relationships %K self-esteem %K self-efficacy %K social support %K intimate relationships %U https://journals.sagepub.com/doi/full/10.1177/1948550617750734
