The article discloses the psychological meaning of resilience, which includes meaningful life orientations that shape a person's adaptive potential. The purpose of the article is to study the phenomenon of resilience as the ability to form effective ways to overcome negative environmental impacts. The Connor-Davidson Stress Resistance Scale-10 (CD-RISC-10) was used among the psychodiagnostic methods of assessing stress resistance. The Bath Ankylosing Spondylitis Metrology Index (BASMI) and the Bath Ankylosing Spondylitis Functional Index (BASFI) were used to assess the functional status of respondents (trauma witnesses). The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was used to determine the activity of psychotrauma. To assess the quality of life, a specific questionnaire of the quality of life of the studied Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) was used. Vitality is ensured by a number of physiological, personal and social factors. The identification and specification of a person's characterological resources contribute to the determination of his resistance, personal potentials that would contribute to the preservation of a person's psychosomatic health, his According to the research results, we defined the categories of low stress resistance, which corresponded to 50 people (24 women and 26 men), moderate stress resistance was determined in 12 people, and the category of high stress resistance corresponded to 1 male respondent. We found certain gender differences in the stress resistance of the victims: it is higher in men. Respondents with high trauma were characterized by a significant loss of psychofunctional ability according to the BASFI scale. The presence of significant violations of psychofunctional ability was confirmed by the BASMI metrological index and the ASQoL quality of life questionnaire.
