خلاصه	The Palliative Performance Scale (PPS) is an 11-point clinician-rated functional assessment tool for patients with advanced, life-limiting illness. Developed by Anderson and colleagues in 1996, it measures overall performance status from 100% (normal) to 0% (death), integrating five domains of functional decline. The PPS is widely used in palliative care, hospice, and oncology settings to guide treatment intensity, prognostication, and care planning.	The Patient Dignity Inventory (PDI) is a 25-item self-report measure assessing dignity-related distress in patients with advanced cancer and life-limiting illness. Developed by Chochinov and colleagues at the University of Manitoba in 2008, the PDI operationalizes 'dignity' as a multidimensional construct encompassing illness-related functional decline, psychosocial concerns (fear, hopelessness, suicidality), body image distress, existential meaning, and social connection—dimensions often overlooked by symptom-focused assessment. The PDI enables clinicians to identify and address dignity threats systematically, preventing the existential despair that can accompany terminal illness even when physical symptoms are well-controlled.
