Anxiety disorders can be differentiated by which diagnostic criteria?

Choice A reason: While many anxiety disorders share core physiological symptoms, they are differentiated primarily by their triggers. For example, social anxiety disorder is triggered by social scrutiny, specific phobias by distinct objects like spiders or heights, and agoraphobia by situations where escape might be difficult. Identifying the specific environmental or cognitive cues is the most reliable method for distinguishing between the various anxiety diagnoses. Choice B reason: The presence of autonomic arousal is a common feature across almost all anxiety disorders and panic-related conditions. Because it is a universal symptom—including symptoms like a racing heart or sweating—it lacks the specificity required to differentiate one disorder from another. It confirms the presence of an anxiety-related state but does not pinpoint the specific diagnostic category. Choice C reason: Nervousness or edginess are subjective global symptoms often found in generalized anxiety disorder, post-traumatic stress disorder, and even depressive disorders. These feelings are too generalized to serve as the primary differentiating factor. They represent the "distress" component of anxiety but do not provide the contextual information needed to separate, for instance, a panic disorder from a social phobia. Choice D reason: Worry is a hallmark feature of many psychiatric conditions, most notably generalized anxiety disorder. However, since individuals with OCD, social anxiety, and even illness anxiety disorder all experience significant worry, the presence of worry alone is not sufficient for differentiation. The practitioner must instead look at "what" the person is worrying about to make an accurate differential diagnosis.
