Anxiety scales are tools used to measure the level of anxiety a person experiences. These scales often consist of a series of questions or statements that individuals rate based on their feelings or behaviors. Common examples include the Beck Anxiety Inventory and the Generalized Anxiety Disorder 7-item scale (GAD-7). These scales help healthcare professionals assess anxiety severity and track changes over time. They can be used in clinical settings or for research purposes, providing valuable data to guide treatment decisions and evaluate the effectiveness of interventions.
