Impact of physical activity on Chinese college students' "going into the world" psychology: chain mediating effects of hardiness and positive academic emotions.

Introduction: Based on positive psychology and emotion regulation theory, this study constructed a chain mediation model to explore the mechanism through which physical activity influences Chinese college students' "Going into the World" psychology, specifically examining the mediating roles of hardiness and positive academic emotions. Methods: A total of 755 college students were surveyed using cluster random sampling. The instruments employed included the Physical Activity Rating Scale-3 (PARS-3), the Hardiness Scale (HS), the Academic Emotions Questionnaire (AEQ), and the Scale of Going into the World (SGIW). Data were analyzed using correlation analysis, regression analysis, and bootstrap mediation tests (Model 6, 5000 samples). Results: Correlation analysis revealed significant positive correlations between physical activity, hardiness, positive academic emotions, and "Going into the World" psychology. Regression analysis indicated that physical activity not only directly and positively predicted "Going into the World" psychology (B = 0.1489, Discussion: The results indicate that physical activity enhances college students' "Going into the World" psychology both directly and indirectly by improving their hardiness and positive academic emotions. This study provides a theoretical foundation and practical pathways for promoting college students' mental health and social adaptation through physical activity interventions, highlighting the particular importance of fostering psychological hardiness.
