概要	The Texas Revised Inventory of Grief (TRIG) is a 21-item multidimensional measure developed by Faschingbauer, Zisook, and DeVaul in 1987 to assess both past grief behaviors (how the person grieved when the death occurred) and present grief feelings (current emotional response to loss). The TRIG is unique in distinguishing historical grief response from contemporary grief state, providing a comprehensive temporal and dimensional profile of bereavement.	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.
