[Homogeneity of defence mechanisms in a group of infarct patients and impact of these defences on the expression of their emotions (author's transl)].

This study made use of the EMO-Questionnaire of Baehr and Baehr and the DMI of gleser and Ihilevich. The first purpose of this study is to evaluate the homogeneity of a group of infarct patients as to what the defence mechanisms are concerned. The wards statistical procedure showed the group was composed of two subgroups amounting respectively 66% (group I) and 34% (group II) of the subjects. The discriminant function analysis reveals how much the two groups are differentiated but coherent. The subjects of group I use predominately intellectualization and denegation; they use moderately turning against self and projection; they use rarely turning against object. The subjects of group II make moderately use of all these defence mechanisms. The second purpose is to precise in which measure the way of expression of affects is related to the defence mechanisms. The U-test of Mann Whitney reveals lower scores among the subjects of group I as compared to those of group II, in aggressiveness, anxiety, inferiority feelings, somatisation, fantasy productions and withdrawal.
