概要	The Bereavement Risk Index (BRI) is a structured assessment tool designed to identify bereaved individuals at elevated risk for complicated grief, depression, or other adverse bereavement outcomes. By systematically evaluating established risk factors (manner of death, relationship quality, concurrent stressors, prior loss history, social support), the BRI facilitates early identification and risk stratification to guide prevention and targeted intervention.	The Inventory of Complicated Grief (ICG) is a 19-item self-report measure developed by Prigerson and colleagues in 1995 to assess complicated grief—a persistent, impairing form of grief that goes beyond typical bereavement. Designed to distinguish complicated grief from bereavement-related depression, the ICG has become the gold-standard screening and diagnostic instrument in bereavement research and clinical practice.
