Neuroticism and age of onset for agoraphobia with panic attacks.

The study of the age of onset of psychiatric conditions can provide some clues to the aetiology of these disorders. A number of studies have examined the age of onset in agoraphobia but results have varied. This may be associated with small sample sizes or differences in populations. There has been very little work examining the factors determining age of onset. The present study examines age of onset in relation to sex and personality. Results indicate no sex differences in age of onset, but an association with age and high levels of neuroticism.
