Sintesi	The PTSD Checklist for DSM-5 (PCL-5) is a 20-item self-report measure of posttraumatic stress disorder (PTSD) symptoms aligned with DSM-5 diagnostic criteria. Developed by Weathers, Litz, and Keane, it is the gold standard screening and outcome measure for PTSD in military, veteran, and civilian trauma populations. The PCL-5 assesses four symptom clusters: re-experiencing, avoidance, negative alterations in cognition and mood, and hyperarousal.	The Geriatric Depression Scale (GDS) is a 30-item self-report depression screening instrument specifically designed for older adults. Developed by Yesavage, Brink, and colleagues in 1982, the GDS addresses the unique presentation of depression in aging populations, where symptoms may differ from younger adults. A validated 15-item short form (GDS-15) is widely used in primary care and community settings for rapid screening.
