Two studies have identified
groups of girls exhibiting chronically high levels of antisocial behavior across childhood and early adolescence and having an increased risk for continued antisocial behavior.60 In addition, Odgers and several colleagues found that 7.5 percent of all girls between the
ages of seven and fifteen displayed an early - onset of offending that persisted into adolescence and that this pattern was similar to boys of the same
age.61
Other studies suggest that although strongly
aggressive behavior in girls before the
age of seven is rare, continuity of offending for such girls may be stronger
than that among comparable boys and that such early problem behavior in girls should be considered a significant warning sign of potential future problems.62
