Primary behavior disorder refers to various problematic behaviors on the part of children and teens. These can be relatively benign such as biting of the nails or chewing on the inside of the mouth to actions directed outward like vandalism, arson or sexual misconduct. Primary behavior disorder may also manifest in disregard for rules at school or a part-time job.
