A questionnaire was devised to quantify and measure four categories: the behavioral characteristics of Type A, self-restraint and escape: the causes of anxiety; means of relaxation; and symptoms incidental to anxiety. Questionnaire analysis was performed in patients (n = 60) with Meniere's disease and in a control population (n = 936). It was statistically proven that the patient group possessed a stress-causative tendency in behavioral characteristics, felt stranger anxiety and showed more severe symptoms owing to this anxiety. Since the level of anxiety highly correlates with the score of behavioral characteristics and also with severity of symptoms, it seems likely that behavioral characteristics produce the anxiety, which, in turn, results in various symptoms of autonomic nervous disorders. A tendency towards stress-causative behavioral characteristics in Meniere's disease patients may be important in the genesis of endolymphatic hydrops.
