Recent developments in information technology have made it easy for people to "chat" online with others in real time, and many do so regularly. "Virtual" relationships can be attractive, especially for people with social interaction problems in the "real world". This study examines the influence on online chat dependency of three dimensions of social anxiety: general social situation fear, negative evaluation fear, and novel social situation fear. Participants of this study were 454 college students. The survey results show that negative evaluation fear and general social situation fear are relative to online chat dependency, while novel social situation fear does not seem to be a relevant factor.
