### **Overview** The **Brief Symptom Inventory 18 (BSI 18)** is a shortened version of the Brief Symptom Inventory, designed to measure psychological distress across 18 items. It focuses on three key symptom dimensions: somatization, depression, and anxiety. This streamlined tool provides a quick snapshot of a patient's psychological state. ### **Applications** The BSI 18 is used in both clinical and medical settings to assess the severity of psychological symptoms and to monitor patient progress over time. Its brevity makes it ideal for use when time is limited or when frequent assessments are needed, especially in medical environments where psychological symptoms might be intertwined with physical health issues. #Psychological-Test
