In two surveys of nearly 600 people ages 18-83, researchers at Union College in US asked participants about their tendencies in close relationships and their Facebook habits.
The research found that there are at least two kinds of active Facebook users: people who are higher in attachment anxiety, and people who are higher in extraversion.
People who were higher in attachment anxiety - that is, they worry that other people don't love them as much as they want to be loved, and are chronically concerned about rejection and abandonment - reported greater amounts of what the study refers to as "feedback seeking" on Facebook.
"Compared to more secure people, those higher in attachment anxiety are more feedback sensitive," said Joshua Hart, associate professor of psychology and the lead author of the study.

"They report feeling much better about themselves when they get a lot of comments, likes and other feedback on their posts and worse about themselves when their Facebook activity generates little attention," Hart said.
More research is needed to determine the reasons behind extraverts' active Facebook use, researchers said.
