The idea

These disorders differ in what the fear is about. In generalised anxiety disorder (GAD) the worry is about many everyday things, on more days than not, for several months. In agoraphobia the fear is of several situations where escape or help may be hard, such as public transport or crowds. In a specific phobia the fear is of one object or situation and is out of proportion to the real danger.

Blood-injection-injury phobia is unusual: after a brief rise, heart rate and blood pressure fall sharply, so the person may faint. Two self-report scales measure severity: the GAD-7 for general anxiety and the Blood Injection Phobia Inventory (BIPI) for this phobia.

Rules to remember

Common mistake

Students think agoraphobia is only a fear of open spaces. It is a fear of situations where escape or help might be difficult, which includes crowded shops and buses.

Worked example

A patient scores 2, 1, 2, 1, 2, 1 and 2 on the seven GAD-7 items. What is the total, and which severity band is it in?

  1. Add the items: 2 + 1 + 2 + 1 + 2 + 1 + 2 = 11.
  2. Compare with the cut-off points: 10 is moderate and 15 is severe.
  3. 11 is at least 10 but below 15.

Answer: Total 11 out of 21, in the moderate range; this shows severity and is not a diagnosis by itself.
