To investigate the association between shyness and Internet usage, 88 undergraduate students completed the Revised Cheek and Buss Shyness Scale, the Online Cognition Scale, a computer/Internet familiarity scale, the Eysenck Personality Questionnaire Revised (short version) and the Abbreviated Duke Social Support Index. Significant correlations were found between shyness, Internet use, and personality traits. A stepwise regression analysis indicated that shyness was predicted by introversion, neuroticism, and problematic Internet usage as assessed by the Online Cognition Scale.
