The Generalized Anxiety Disorder-7 (GAD-7) is easy to use, and the score will indicate the severity of anxiety symptoms. Depending on the level of anxiety indicated by the results, a more detailed assessment of anxiety may be warranted. GAD-7 is a great scale to use clinically over time (or pre/post treatment) to measure differences in anxiety level over time. For example, clinicians might utilize this scale quarterly with patients to analyze trends.
