In order to investigate the character of patients with bronchial asthma, we studied their chartacteristic traits through Seikenshiki Personality Inventory (INV) which has been well known to reflect the premorbid character. The results were 48 follows. A large number of patient with bronchial asthma were nervous and cyclothymic in the characteristic pattern. The characteristic traits of high frequency were "simple-minded", "insensible", "sympathetic". "hypochondriacal", "sticky" and "restrained". Comparing males with females a to characteristic traits "simple-minded" was more freequently observed in males than in females statistically; "fun'' was often observed in males and "restrained" was often observed iA females. "Precise" was more frequently observed in the oider group than in the younger. Atopic asthmtics were significantly more insensible, restrained and careless than nonatopic asthmatics. Asthmatics with paroxyamal type showed more schizophrenic and hysteric tendencies than those with chronic type in characteristic pattern. "Simple-minded" showed significantly higher frequency in the latter than in former. Comparing mild cases with moderately severe or severe cases as to characteristic pattern, epileptic pattern was highly apparent in mild cases. These reslts suggest that the asthmatic by nature tend to devote themselves to their excessive adaptation. Moreover, their characteristic traits might influence their chinical courses.
