This study examined social anxiety and social passivity as main components of shyness. Two questionnaire studies were conducted with undergraduate samples. Main results were as follows: Preliminary and confirmatory factor analyses showed that the two components were separate dimensions. Social anxiety correlated positively with public self-consciousness and need to avoid social rejection, and negatively with self-esteem. On the other hand, social passivity correlated negatively with social skill and need for social approval. The results suggest that social anxiety reflects hypersensitivity to social rejection, and social passivity helplessness to form and manage social relationship. A new model of shyness is discussed, in relation to Leary's (1983b) self-presentation model.

Key words: shyness, social anxiety, social passivity, self-consciousness, social skill
