خلاصه	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.	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.
