Too much chat about their problems may lead middle school–age girls into depression, according to a recent study at Stony Brook University. Past research indicates that girls are more likely than boys are to co-ruminate, repeatedly discussing difficulties with friends, speculating about causes and excessively dwelling on negative emotions. In the new study, psychologists confirmed that girls who co-ruminate more often than their peers have more depressive symptoms. They also found a new link with romantic experience: corumination was most likely to result in depressive symptoms among girls who were most active romantically.
