概要	The Prolonged Grief Disorder Scale (PG-13) is a 13-item diagnostic assessment tool developed by Prigerson and Maciejewski to operationalize the DSM-5-TR diagnostic criteria for Prolonged Grief Disorder. Designed as a structured clinical instrument, the PG-13 directly maps onto the symptomatic, cognitive, and functional criteria required for diagnosis, making it invaluable in clinical and research settings where standardized diagnostic assessment is needed.	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.
