The "Giessen-Test" is a psychological test in form of a questionnaire, basing on self-assessment. It was applied in 63 patients with bronchial asthma in order to get their "self-images" and their "ideal-self-images". Except of higher values for depression the "self-images" of the asthmatics resembled very closely those of normals. The ideals ("ideal-self-image") of the patients were uncharacteristic and reflected general trends. In contrast to these findings eleven physicians had a negative conception of asthmatic patients ("foreign image"). Physicians assessed the asthmatics to be disliked ("negative social resonant"), obstinate ("dominant") and depressive. Patients with exogen-allergic asthma, intrinsic asthma and asthma of unknown origin differ from each other only within a few marks. These differences, however, are not sufficient, to allow to coordinate a specific personality-structure with one of the different kinds of asthma.
