خلاصه	The Bereavement Risk Index (BRI) is a structured assessment tool designed to identify bereaved individuals at elevated risk for complicated grief, depression, or other adverse bereavement outcomes. By systematically evaluating established risk factors (manner of death, relationship quality, concurrent stressors, prior loss history, social support), the BRI facilitates early identification and risk stratification to guide prevention and targeted intervention.	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.
