Tóm tắt	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 Anticipatory Grief Scale (AGS) is a measure developed by Theut, Jordan, and colleagues in 1990 to assess grief responses in individuals facing impending loss—such as family members caring for a terminally ill loved one or anticipating a predicted death. The AGS captures the emotional burden, depression, existential concern, and functional disruption that often precede and accompany the final illness period, distinct from post-death grief.
