The World Health Organization defines violence as the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community that either results in or has a high likelihood of resulting in injury, death, psychological harm, mal-development or deprivation. The inclusion of the word ‘‘power’’, in addition to the phrase ‘‘use of physical force’’, broadens the nature of a violent act and expands the conventional understanding of violence to include those acts that result from a power relationship, including threats and intimidation. The ‘‘use of power’’ also serves to include neglect or acts of omission, in addition to the more obvious violent acts of commission.
