Actually, it was the reverse — the authors discussed
early maturation (
puberty) and antisocial behavior in teenage girls as the variables that
predict having a large percentage of male friends.
Some support has been found for an association between hormonal concentrations and negative affect20 - 24; however, social factors, including negative life events and their interaction with pubertal status (but not hormonal status), account for more of the variance in negative affect than biological factors alone.25
Early pubertal timing and its social implications have also been postulated as an important risk factor in girls.26 - 31 Two recent studies, however, report that pubertal status has a greater influence in
predicting female depression than age32, 33 or the timing of
puberty.32
