The test contains several sections that are responsible for a certain sign of stress - intellectual, behavioral signs, emotional and physiological symptoms. 2. \"Questionnaire for self-diagnosis of the type of behavior in a stressful situation\" (according to V. Boyko), which allows you to identify reactions to stress and the tendency to be influenced by stressogenic factors depending on the type of behavior in a stressful situation. Analysis, synthesis, generalization, concretization, systematization, comparison, forecasting, and mathematical statistics were used to process, compare, evaluate, and interpret the obtained research results.
