The Generalized Anxiety Disorder 7-item scale (GAD-7) is a self-report questionnaire designed to assess the severity of generalized anxiety disorder. It consists of seven questions that ask individuals about their feelings and experiences over the past two weeks. Each item is scored from 0 to 3, allowing for a total score ranging from 0 to 21, with higher scores indicating greater anxiety levels. The GAD-7 is widely used in clinical and research settings due to its simplicity and effectiveness. It helps healthcare providers identify individuals who may need further evaluation or treatment for anxiety disorders, facilitating timely intervention and support.
