Dataset for: Emotional Stability and Optimism as Core Protective Factors of Subjective Well-Being in Youth Facing Wartime Uncertainty

This dataset contains de-identified psychometric data from a convenience sample of Ukrainian young adults (N = 161; 84% women; Mage = 22.5, SD = 4.2, range 18–36 years) collected to examine the relationships among the Big Five personality traits, dispositional optimism, emotional stability, and subjective well-being under conditions of prolonged wartime uncertainty. The data includes responses from the Ten-Item Personality Inventory (TIPI-UKR), the Life Orientation Test–Revised (LOT-R), and the Subjective Well-Being Scale. To ensure comparability across instruments with varying response formats, all raw scores were transformed and normalized to a common 0–100 metric. The dataset contains no missing values.
