Type A behavior pattern and illness other than coronary heart disease

The paper presents three independent studies. Two are retrospective and one prospective. In the first study three equal groups of subjects participated: 30 myocardial infarction patients, 30 peptic ulcer patients and 30 healthy controls. The second study was run on three groups of military pilots: 36 had diverse cardiological problems, 47 were peptic ulcer patients and 64 were healthy control pilots. The prospective study included military pilots too. The Jenkins Activity Survey, Form C was used to assess the Type A behavior pattern in all subjects. The results of all three studies show high consistency. Persons with circulatory disorders obtained similar scores on Subscale A as those with digestive disorders, and both groups of patients scored significantly higher than the healthy controls. A similar pattern of data was found for the Speed and Impatience Subscale.
