| Tiivistelmä≠ | The Somatic Symptom Scale-8 is a brief eight-item self-report instrument designed by Bernd Gierk and colleagues to assess the severity and burden of somatic (bodily) symptoms. Published in JAMA Internal Medicine in 2014, the SSS-8 is derived from the longer Somatic Symptom Disorder-B Criteria Scale and serves as a rapid screening tool for somatic symptom disorder and medically unexplained symptoms. It is widely used in primary care, general medicine, and psychiatry to identify patients whose physical complaints may warrant psychological or behavioral intervention. | The Patient Global Impression of Change is a single-item, seven-point rating scale asking patients to report their overall impression of change since treatment initiation. Originally published by William Guy in the ECDEU Assessment Manual in 1976, the PGIC has become a standard co-primary endpoint in clinical trials assessing treatment efficacy. The scale is endorsed by the FDA as a patient-reported outcome measure for demonstrating clinical benefit. Despite its simplicity, the PGIC captures patients' holistic perception of improvement—integrating symptom reduction, functional recovery, and subjective well-being. |
