Behavioral problems are undesirable behaviors that are disruptive to environment or to child itself. This contains, as an example, aggressive, hot-tempered or disobedient behavior. This also contains destructiveness or bullying.
These are mainly externalizing behavioral problems, because they are outward and others-oriented. Occasionally internalizing behavioral problems are also contained, such as fear of failure. If the problem behavior lasts more long than six months, it may be a conduct disorder.
