The GAD-7 is a widely used screening tool designed to assess the severity of generalized anxiety disorder. It consists of seven questions that ask individuals about their anxiety symptoms over the past two weeks. Each question is scored from 0 to 3, allowing for a total score that helps determine the level of anxiety experienced. Healthcare professionals often use the GAD-7 in clinical settings to identify patients who may need further evaluation or treatment for anxiety. The tool is valued for its simplicity and effectiveness, making it accessible for both patients and providers in various healthcare environments.
