Abstract
This research examines the intricate connections among three key elements: an individual’s ability to tolerate sources of stress, their willingness to adapt to new situations, and various psychological factors that influence human behavior. To analyze these relationships, the study employs a sophisticated statistical technique known as partial least squares structural equation modeling (PLS-SEM). A total of 327 Kazakhstan residents voluntarily participated in the study, comprising 84.6% women and 15.4% men, with ages ranging from 14 to 67 years old. “Stress Source Tolerance Scale” examined stress tolerance, “Personality Readiness Scale” measured readiness to change, and “Fatigue, Monotony, Satiety and Stress Questionnaire” investigated psychological states. The results indicate significant direct and indirect effects of self-esteem, others’ perceptions, and world perceptions on stress tolerance, readiness for change, and psychological states. Moreover, systematic preference has a significant mediating effect on the relationship between openness to change and psychological states. Results suggest that understanding these complex relationships may have implications for health, organizational effectiveness, and psychological well-being.
