A team at Edinburgh Napier University gathered online survey responses from 175 students about their feelings towards Facebook. Almost three quarters of respondents were women.
Dr. Kathy Charles, who led the study, said: "We found it was actually those with the most contacts, those who had invested the most time in the site, who were the ones most likely to be stressed. "It's like being a mini news channel about yourself. The more people you have the more you feel there is an audience there. You are almost a mini celebrity and the bigger the audience the more pressure you feel to produce something about yourself."
