Adults with Violent or Aggressive Behaviour
The World Health Organisation defines violence as "the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation".
This definition associates intentionality with the committing of the act itself, irrespective of the outcome it produces. Generally, though, anything that is turbulent or excited in an injurious, damaging or destructive way, or presenting risk accordingly, may be described as violent or occurring violently, even if not signifying violence (by a person and against a person).
Aggression is overt, often harmful, social interaction with the intention of inflicting damage or other unpleasantness upon another individual. It may occur either in retaliation or without provocation. In humans, frustration due to blocked goals can cause aggression.
Aggression can take a variety of forms which may be expressed physically or communicated verbally or non-verbally.
