Women are more likely than men to suffer from romantic jealousy that's brought on by Facebook posts-- especially if they think other people can see that their relationship might be in trouble.

In the study, about 250 college-age men and women were asked to imagine that they had found a picture of their significant other with a person of the opposite sex on Facebook. Women had greater feelings of jealousy when they imagined it compared to men. Women rated their level of jealousy as a six out of a possible nine, compared to a four out of nine for men.

Women and men reported had the most jealousy if the picture's privacy settings meant that it couldn't be seen by other people on Facebook. They took that to mean their sweetie was trying to hide something. If the pic could be seen by other people on Facebook, men's jealousy dropped, but women's stayed high.

Women were also more hurt than men if there were few photos of them with their partner on Facebook.

** Other studies have found that people who spend more time on Facebook have higher levels of romantic jealously and more frequent viewing of their partner's Facebook profile.
