General Information

The Broset Violence Checklist (BVC) is a useful instrument in predicting violence within the next 24-hour period of completing the questionnaire. It assesses confusion, irritability, boisterousness, verbal threats, and attacks on objects as either present or absent. It is hypothesized that an individual displaying two or more of these behaviors is more likely to be violent in the next 24-hour period.
