The most effective method for predicting violent behavior within 24 hours.

The Brøset Violence Checklist (BVC) is a risk assessment tool that can predict aggression in a 24 hour perpective. It has proven its value scientifically and practically. The BVC is in use in more than 40 countries and in a variety of settings in health care and beyond in order to improve workplace safety and to save costs.

The BVC assists in the prediction of imminent violent behaviour with only 6 questions.

The Brøset Violence Checklist is a 6-item checklist which assists in the prediction of imminent violent behaviour (24 hrs perspective). The BVC found its origin in Mental Health care and can be used by all staff working with patients or clients. When used appropriately it helps to predict and prevent unwanted behaviour among in a variety of setting, also outside Mental Health care. The checklist is well underpinned by research including several RCT’s in a number of countries and settings. As a result it improves the therapeutic climate among fellow patients and staff and even saves lives and therefor cuts down heavily on safety costs. The BVC can also work well in other organisations in other sectors than healthcare that deal with aggression and other unwanted behaviour as well as reducing use of restrictive measures such as restraint and seclusion - in line with political ambitions on national and international level.

How does the BVC method work?

A brief explenation, how to use the BVC

1. Observe the client.

When using the BVC professionals are observing 6 items/behaviours in their usual interaction with clients/patients. With the BVC the observations are systematized and documented using an evidence based tool for violence risk assessment.

The BVC uses 6 different items that reflect that mood setting. 

Items which indicates the risk of violence.

  • Confused

    Appears obviously confused and disoriented. May be unaware of time, place or person.

  • Irritable

    Easily annoyed or angered. Unable to tolerate the presence of others.

  • Boisterous

    Behaviour is overtly 'loud' or noisy. For example slams doors, shouts out when talking etc.

  • Physical threats

    Where there is a definite intent to physically threaten another person. For example talking of an aggressive stance; the grabbing of another persons clothing; the raising of an arm, leg, making of a fist or modelling of head-butt directed at another.

  • Verbal threats

    A verbal outburst which is more than just a raised voice; and where there is a definite intent to intimidate or threaten another person. For exampe verbal attcks, abuse, name calling, verbally neutra comments uttered in a snarling aggressive manner.

  • Attacking objects

    An attack directed at an object and not an individual. For example the indiscriminate throwing of an object; banging or slamming windows; kicking, banging or head-butting an object; or the smashing of furniture. 

2. Score the client.

The BVC is quick and easy-to-use, one needs to score on 6 items only, which can be done within a minute. Absence of behavior gives a score of 0. Presence of behavior gives a score of 1. 

For example, if a well know client normally is confused (has been so far a long time) this will give a score of 0. If an increase in confusion is observed this gives a score of 1.

Score on absence or presence of each behavior.

  • 1. Is the patient confused?1
  • 2. Is the patient irritable?1
  • 3. Is the patient behaving boisterous?0
  • 4. Does the patient threat verbally?1
  • 5. Is the patient physical threatening?0
  • 6. Does the patient attack objects?0
  • The sum of the total score.3
  • 0 The risk of violence is small.
  • 1-2 The risk of violence is moderate. Preventive measures should be taken.
  • 3-6 The risk of violence is high. Preventative measures should be taken and plans about how to manage an attack made.

3. Analyse and adjust

The total sum of scores indicates that the risk of violence is either small (0), moderate (1-2) preventive measures should be taken, or high (>2) preventive measures should be taken and plans about how to manage an attack should be made. After a period of time policies can be adjusted on 

different organisational levels in order to minimize the risk of violence. This will result in a friendly work floor, less aggression and even saves lives.
