Although it has been suggested that an understanding of shyness may come from a better understanding of social anxiety, there is no hard evidence that shy people are in fact socially anxious. To explore the link between shyness and social anxiety, a 297-item questionnaire was administered to 302 college students. Analysis of the 100 questionnaire items related to shyness and social anxiety yielded 21 factors, with five factors accounting for 46 percent of the total variance. The data suggested that timidity, audience anxiety, and interpersonal anxiety are separate, distinguishable constructs. Shyness was more closely linked to timidity than to interaction anxiety and had relatively little to do with audience anxiety or stagefright. The results also suggested that some shy subjects are both timid and anxious, others are timid but not anxious, and still other shy subjects are anxious but not timid. These data suggest caution in linking shyness and interaction anxiety too closely. Researchers should use the term shyness to refer only to social inhibition or timidity, and resist the temptation shown by some subjects to call themselves shy when they mean they are simply socially anxious. Questionnaire items dealing with each variable are included. (JAC)
