Patients with Meniere's disease as well as two control groups (non-Meniere peripheral vertigo and chronic otitis media) were tested with a Japanese version of the Maudsley Personality Inventory (MPI).
Patients with Meniere's disease showed significantly lower L (lying) scores of the MPI than each control group, and higher E (extraversion-introversion) scores than with chronic otitis media.
There was no significant difference of N (neuroticism) scores between patients with Meniere's disease and each control group.
The scores of each group were compared with reported data on normal Japanese adults. Patients with Meniere's disease had significantly lower L scores and those with chronic otitis media had significantly lower E scores than normal Japanese adults.
The tendency of low L scores of patients with Meniere's disease was found to have no significant relation to the patients' age, degree of hearing loss or duration of the disease.
