概要	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.	The Grief Experience Questionnaire (GEQ) is a multidimensional measure developed by Barrett and Schneweis in 1980 to assess the breadth of emotional, cognitive, and existential experiences reported by bereaved individuals. Rather than focusing on pathology or symptom severity, the GEQ captures the diverse phenomenology of grief—including yearning, social withdrawal, guilt, anger, disorientation, and existential questioning—providing a comprehensive portrait of the grief experience.
