This resource was developed by the Bureau of Justice Assistance’s National Consortium on Preventing Law Enforcement Suicide (the Consortium) and focuses on the role peer support has in preventing officer suicide. The Consortium, led by the International Association of Chiefs of Police (IACP) in partnership with Education Development Center (EDC) and the National Action Alliance on Suicide Prevention (Action Alliance), brought together law enforcement leaders alongside mental health and suicide prevention experts across the nation to address preventing suicide in law enforcement. Through the Consortium, five task force groups were formed to identify recommendations and considerations for the policing profession as it relates to suicide prevention efforts in an agency or department: messaging, data and research, organization and system change, peer support, and family support. Peer support is a key component in the Comprehensive Framework for Law Enforcement Suicide Prevention. This resource outlines how peer support can best integrate suicide prevention strategies to support fellow officers.
