Which statement is accurate about generalized anxiety disorder?

B) It represents all five of the dimensions on the PAINeD model.
C) It is the only mood disorder associated with personality traits.
D) It is a form of free-floating anxiety not tied to any identifiable stimulus.

Generalized anxiety disorder is characterized by excessive and uncontrollable worry and anxiety about a variety of different things, often with no specific trigger or cause. Therefore, it is considered a form of free-floating anxiety not tied to any identifiable stimulus. Option A is incorrect because generalized anxiety disorder is not necessarily the basis for other mood disorders, but it may co-occur with them. Option B is incorrect because the PAINeD model represents five dimensions of pain assessment, not anxiety disorders. Option C is incorrect because other mood disorders, such as major depression and bipolar disorder, can be associated with personality traits as well.
