Rezumat	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 PHQ-9 is a brief, nine-item self-report questionnaire developed by Kroenke, Spitzer, and Williams to screen for and measure the severity of depressive symptoms. Published in 2001 in the Journal of General Internal Medicine, it has become one of the most widely used depression screening instruments globally. The scale maps directly to DSM-IV diagnostic criteria for major depressive disorder, making it valuable in both clinical and research settings.
