MANHATTAN, Kan. – People who act violently often provide warning signs of negative behavior. By recognizing these signs, people may stop the violence before it escalates, or protect themselves from an attack.

K-State Research and Extension specialist Elaine Johannes provides the following tips to recognize the potential for violent behavior:

Warning signs of violence against others:

* loss of temper on a regular basis

* frequent physical fighting

* significant vandalism or property damage

* increase in use of drugs or alcohol

* increase in risk-taking behavior

* detailed plans to commit acts of violence

* announcing threats or plans for hurting others

* enjoying hurting animals

* carrying a weapon

Warning signs of violence against self:

* previous suicide attempts

* significant alcohol or drug use

* threatening or communicating thoughts of suicide, death or dying

* sudden increase in moodiness, withdrawal or isolation

* major change in eating or sleeping habits

* feeling of hopelessness, guilt or worthlessness

* poor control over behavior

* drop in quality of school performance or interest

* lack of interest in usual activity

* getting into trouble with authority figures

* perfectionism

* giving away important possessions

* hinting at not being around in the future or saying goodbye

"Alone, these warning signs may not be of concern, but together and over time, they may indicate a strong potential for violence," Johannes said. "If these signs exist, seek advice and help from local resources, such as law enforcement, mental health agencies, school-site support staff and others."
