The rapid digitalization of modern life necessitates robust digital literacy skills. Mental toughness, a crucial psychological attribute, also underpins success in various domains. This study investigates the potential relationship between these two constructs in the context of kickboxing athletes. A total of 242 athletes (N=95 female, N=147 male) participated in the study. Digital literacy was assessed via a validated scale encompassing four subdimensions: attitude, technique, cognitive skills, and social engagement. Mental toughness was measured via established scales. Descriptive statistics, correlational analyses, and regression models were employed to examine the relationships between the variables. Confirmatory factor analysis (CFA) confirmed the constructs’ structural validity. Positive correlations were found between all four subdimensions of digital literacy and mental toughness. Regression analysis revealed significant positive impacts of the attitude (β = 0.155), technique (β = 0.190), and social dimensions (β = 0.173) of digital literacy on mental toughness. Findings suggest a robust association between digital literacy and mental toughness in athletes. Increased positive attitudes, strong technical skills, and active social engagement in the digital realm contribute to enhanced mental resilience. Future research should explore potential interventions to foster digital literacy in athletes, potentially leading to improved mental fortitude and performance.
