BACKGROUND: Internet addiction (IA) is prevalent among university students and is often linked to negative affect and maladaptive cognition. Time-specific physical activity such as night running may relate to IA, but the psychological mechanisms remain underexplored.
OBJECTIVE: This study examined the association between night running and IA and tested whether stress/anxiety and rumination mediate this relationship in a serial pathway.
METHODS: A cross-sectional online survey was conducted among 1,138 undergraduates from two universities in Guangdong Province, China. Night running frequency (after 7:00 p.m.) was assessed using an adapted IPAQ-SF item. Stress/anxiety was measured with the DASS-21, rumination with the Ruminative Responses Scale, and IA with the Internet Addiction Test. Correlations were computed and a serial mediation model was tested using bootstrapping.
RESULTS: Night running was negatively correlated with stress/anxiety (r = -0.48), rumination (r = -0.45), and IA (r = -0.52), while stress/anxiety and rumination were positively associated with IA (r = 0.42 and r = 0.50, respectively). Mediation analyses indicated a significant total effect of night running on IA (β = -0.52) and a remaining direct effect (β = -0.34). Significant indirect effects were observed via stress/anxiety (β = -0.05), via rumination (β = -0.07), and via the serial pathway (β = -0.06), with all bootstrap 95% CIs excluding zero.
CONCLUSION: Night running is associated with lower IA among university students, partly through reduced stress/anxiety and reduced rumination, supporting a partial serial mediation model.
