Evaluation of a screening interview for Briquet syndrome (hysteria) by the study of medically ill women.

A screening interview for Briquet syndrome consisting of 14 symptom questions was administered to a group of 50 medically ill women. No patient was found eligible for a diagnosis of Briquet syndrome, a frequency less than the estimated general population prevalence of 1% to 2%. When symptoms explainable by known organic disorder were considered positive, 14% of patients became eligible for the diagnosis. We consider this a low enough rate to allow screening by lay interviewers. A frequency distribution of symptoms comparing the medically ill women and a group of psychiatric clinic women with Briquet syndrome shows that the Briquet group had both more symptoms and distinctive patterns of symptoms.
