Hysterical personality disorder. The process of diagnosis in clinical and experimental settings.

A study of the case notes of 52 patients with a diagnosis of hysterical personality disorder showed that 27 had no recorded features of that condition, but were frequently described as aggressive, uncooperative, or attention-seeking. Although 60% were recorded as depressed, only 17% received antidepressant treatment. In an experimental study, the core traits of the disorder were found to have a low inter-rater reliability. Two patients, who had received hospital diagnoses of hysterical personality disorder, were shown to display behaviour that caused psychiatrists to make a diagnosis on wholly inadequate information.
