Blood-injection-injury phobia involves stimulus-bound fear and faintness. The present paper outlines a program of research that has been investigating the nature of symptoms elicited by these stimuli. The structure of the symptoms and their heritability is examined, and it is speculated that the symptoms may form a triphasic response of anticipatory anxiety, stimulus-bound fear, and faintness. The treatments for blood-injury-injection phobia are examined, and data suggesting ways to improve existing treatments are outlined.
