The analysed problem dealt with personality determinants of susceptibility to iatrogenic psychical trauma. A group of 35 female patients with coronary disease and another group consisting of 35 healthy women were tested with C.D. Spielberger's State-Trait Anxiety Inventory, Z. Bizoń's Questionnaire of Neurotic Symptoms, J.B. Rotter's I-E Scale, and the author's own method for the determination of susceptibility to iatrogenic psychical trauma. In comparison with healthy women, the patients displayed significantly higher level of anxiety both as a state and as a trait, lower level of psychical endurance, more external sense of control and higher susceptibility to iatrogenic trauma. More over, the patients with lower psychical endurance and external sense of control displayed high susceptibility to iatrogenic psychical trauma.
