Development and validation of stress assessment and psychological recovery methodology: experience of Ukrainian citizens in the context of war

The article examines the process of development and validation of a new methodology for assessing stressful events, stress reactions, and resilience in the Ukrainian sample. Three stages of research were conducted: collection of primary data from 150 respondents, formation of a questionnaire based on typical answers, and testing to verify the reliability and validity of the instrument on a sample of 123 people. The research used the method of test-retest reliability, as well as Cronbach's alpha to assess the internal consistency of the scales. The results confirmed the high reliability and validity of the new technique, which can be used to measure psychological resilience in the context of war and extreme events.
