The article examines the concept of psychotrauma, post-traumatic stress disorder, the process of psychotraumatization and its degree of impact on the personality. Post-traumatic stress disorder in the work is considered in more detail as a special case of psychotraumatization. During the period of exposure to a stressor, a person experiences severe stress and psychotraumatization. The assessment of the degree of trauma was carried out according to the method of the same name (by A.N. Kalinina). The study studied the degree of psychotraumatization of the individual and the consequences of the process of psychotraumatization, expressed in changes in mental activity. The degree of psychotraumatization depends on the psychological characteristics of a particular person. The author presents the results of a study of anxious-phobic patients and healthy people. A comparative analysis of the degree of psychotramatization showed a higher level of psychotraumatization in patients with anxiety-phobic disorders compared with healthy people. The level of trauma in the experimental group is classified as moderate and severe, while in the control group it is mild. The data obtained in the study can be used by psychologists and social workers in programs to reduce the degree of psychotraumatization in adults.
