%0 Journal Article %T Self-concept and self-esteem: How the content of the self-concept reveals sources and functions of self-esteem %A Kinga Lachowicz-Tabaczek %A Justyna nieci¨˝ska %J Polish Psychological Bulletin %D 2011 %I %R 10.2478/v10059-011-0005-y %X The relations of content of self-concept to self-esteem may reflect the role of different factors in developing self-esteem. On the basis of theories describing sources of self-esteem, we distinguished four domains of self-beliefs: agency, morality, strength and energy to act, and acceptance by others, which we hypothesized to be related to self-esteem. In two studies, involving 411 university students, the relationship between self-esteem and self-concept was examined. The results confirmed relative independence of these four domains. Self-evaluation of agency was the strongest predictor of self-esteem, followed by self-evaluation of strength and energy to act, and self-evaluation of acceptance by others. Self-evaluation regarding morality turned out to have either no or negative relationship with self-esteem. The results supported the theories assuming that either perception of one's own agency or acceptance by others are sources of self-esteem. %K self-esteem %K self-concept %K sources and functions of self-esteem %U http://versita.metapress.com/content/a1737u4m74461538/?p=da92669768654535950e41efc656f45c&pi=4
