In a quest to learn what leads some people to turn to Facebook to connect with others, doctoral student Russell Clayton of the Missouri School of Journalism found that anxiety and alcohol use seem to play a big role. For his master's thesis, which appears in the May issue of Computers in Human Behavior, Clayton surveyed more than 225 college freshman about two emotions, anxiety and loneliness, and two behaviors, alcohol and marijuana use. He found that the students who reported both higher levels of anxiety and greater alcohol use also appeared the most emotionally connected with Facebook. Those who reported higher levels of loneliness, on the other hand, said they used Facebook to connect with others but were not emotionally connected to it. It probably isn't terribly surprising that those who are anxious may feel more emotionally connected to a virtual social setting than a public one, which Clayton acknowledges in a school news release.
