The aim of this study is to determine whether shyness and emotional expressiveness can be predictive factors of well-being. Participants in this study are people (N = 50) aged between 21 and 64 (M=32.5, SD=4.61) who completed Revised Cheek and Buss Shyness Scale, the Berkeley Expressivity Questionnaire and the Ryff’s Psychological Well-Being Scales. The study tested hypotheses which stipulate that well-being is higher when the level of shyness is lower and that there is a correlation between well-being and emotional expressiveness. The results of the study have shown that there is a negative correlation between shyness and well-being. It also highlighted the fact that there is no significant difference between men and women in terms of shyness, emotional expressiveness and well-being.
