Family and personal factors. The development of adolescent antisocial behavior is often
considered to be the result of a set of family and personal factors, with the child’s aggressive behavior
representing a substantial part of that developmental pattern. For example, children with difficult
temperaments and early behavioral problems are at greater risk for later adolescent aggression and
conduct problems. This developmental course is also set within the child’s social environment. For
example, poor parenting practices, such as poor parental monitoring and supervision and high rates of
harsh and inconsistent discipline, have been shown to contribute to children’s aggressive behavior.
