Blood-injury-illness phobia: a review

The empirical literature that pertains to phobias of blood, injury, or illness (BII) is surveyed. BII phobia is selectively associated with a vasovagal fainting response upon exposure to phobic stimuli, and the clinical entity may represent an exaggeration of a response that is relatively prevalent in the general population. Clinical, demographic and etiological information obtained from a series of 15 BII phobics is presented, and the suggestion is made that this disorder warrants a diagnostic category separate from simple phobia.
