A diagnosis of generalized anxiety disorder requires that the worrying occurs more days than not for how long, and is accompanied by how many of the listed symptoms?

1. Generalized anxiety disorder is a nearly continuous state of excessive, uncontrollable and pointless worry. 2. The worry must occur more days than not for at least six months and must not be part of another disorder. 3. It must also be accompanied by any three of restlessness, poor concentration, fatigue, muscle tension, irritability and sleep difficulty. 4. One month with worry about further attacks belongs to panic disorder, so that pairing is the nearest trap. 5. Five symptoms over two weeks describe major depressive disorder, and two years describes persistent depressive disorder. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 15 "Psychological Disorders", section 15.4 Anxiety Disorders_
