The disparity between urban and rural suicide rates is increasing. In response to this major public health problem, clinicians and school mental health researchers designed a systematic crisis intervention protocol to be used with adolescents presenting with suicidal or homicidal ideation. The prevention of escalating adolescent crisis events (PEACE) protocol is a comprehensive risk assessment designed for use by licensed clinicians working collaboratively with school personnel. A revised and extended version of the PEACE protocol was employed during 68 crisis events involving 42 high school students in 2013–14. These results and clinical implications of utilizing a systematic protocol to address potential suicidal or violence threats are discussed.
