BackgroundThe relation between shyness and self-esteem in women has not been fully elucidated. Shyness is a source of many problems in social interactions, although it may be positively evaluated by women as a stereotypically female trait. The aim of the study was to examine relations between shyness, self-esteem, its dimensions, and contingencies of self-worth in women. It also compared the self-esteem and contingencies of self-worth in shy and bold women.Participants and procedureThe study was conducted in a sample of 1020 Polish women, aged 18-73. The Revised Cheek and Buss Shyness Scale, the Multidimensional Self-Esteem Inventory, and the Contingencies of Self-Worth Scale were used.ResultsThe results of linear multiple regression showed that predictors of shyness were dimensions of self-esteem related to likea-bility, personal power, lovability, body functioning, academic/professional competences, and self-worth conditioned by oth-ers’ approval and God’s love. Shy women had significantly lower global self-esteem in comparison to bold women. Shy women evaluated themselves lower than bold women did, in all the dimensions of self-esteem. Both shy and bold women find family support and academic/professional competencies the main contingencies of self-worth, and God’s love was indi-cated the least.ConclusionsThe results illustrated the importance of shyness for women’s self-esteem, and also have implications for understanding how shy and bold women may express themselves in social life.
