Exploring the Predictive Relationship between Mental Toughness and Subjective Well-Being: A Quantitative Analysis

his study aimed to examine the extent to which mental toughness can predict subjective well-being, thereby contributing to the understanding of psychological factors influencing mental health and quality of life.Utilizing a cross-sectional design, 200participants were assessed using the Mental Toughness Questionnaire (MTQ48) and the Satisfaction with Life Scale (SWLS). Data were analyzed through descriptive statistics and linear regression using SPSS Version 27 to explore the predictive power of mental toughness on subjective well-being.Results indicated that mental toughness significantly predicts subjective well-being, accounting for 23% of the variance. The regression model (F = 5.88, p < 0.01) and standardized coefficients (B = 0.99, β = 0.23, p <0.05) underscored the positive relationship between mental toughness and well-being.The study confirms that mental toughness serves as a significant predictor of subjective well-being. Enhancing mental toughness could, therefore, be a viable strategy forimproving individuals' mental health and overall life satisfaction.
