The Mediating Role of Mental Fatigue Awareness in the Relationship Between Perceived Stress and Psychological Well-Being Among Combat Athletes

AbstractBackground/Objectives. Combat athletes face unique psychological demands, and stress can affect both their cognitive awareness and well-being. This study aimed to examine the mediating role of mental fatigue awareness in the relationship between perceived stress and psychological well-being, providing insights into the structure of psychological resilience in this population.Methods. A total of 303 combat athletes voluntarily participated. Participants completed the Perceived Stress Scale, Mental Fatigue Awareness Scale, and Psychological Well-being Scale. Statistical analyses assessed the direct effects of perceived stress on psychological well-being, the effect of stress on mental fatigue awareness, and the potential mediating role of mental fatigue awareness.Results. Perceived stress significantly increased mental fatigue awareness (b = 0.732 ± 0.064, β = 0.549, p = 0.001) and directly decreased psychological well-being (b = –0.488 ± 0.166, β = –0.191, p = 0.004). Mental fatigue awareness negatively affected psychological well-being (b = –0.374 ± 0.124, β = –0.195, p = 0.003) and partially mediated the relationship between stress and well-being (indirect effect: b = –0.274 ± 0.115, β = –0.107, p = 0.003; 95% CI = –0.504 to –0.049).Conclusion. Perceived stress affects psychological well-being both directly and indirectly through increased mental fatigue awareness. These findings highlight the importance of supporting stress management and coping strategies for mental fatigue to maintain optimal psychological well-being in combat athletes.
