عنوان انگلیسی Physical Exercise and Behavioral Addiction: How Self-Control and Subjective Emptiness Jointly Mediate the Reduction of Short-Video Addiction in Adolescents
چکیده انگلیسی مقاله Background: Short-video addiction is prevalent among adolescents and threatens their development. This study aimed to examine the relationships among physical exercise, self-control, subjective emptiness, and short-video addiction in adolescents and the underlying mechanisms. Methods: A total of 889 adolescents were recruited from 3 middle schools in Zhejiang Province, China. Data collection was conducted from April to June 2025 using a questionnaire. Results: The mean score of short-video addiction in adolescents was 3.01; physical exercise was negatively correlated with short-video addiction (r=−0.626, P<0.001); self-control (effect=−0.106, 95% CI [−0.175, −0.047]) and subjective emptiness (effect=−0.360, 95% CI [−0.492, −0.260]) mediated the relationship between physical exercise and short-video addiction; and the chain mediation model shaped by self-control and subjective emptiness had a statistically significant effect (effect=−0.064, 95% CI [−0.115, −0.025]). Conclusion: Physical exercise contributes to mitigating short-video addiction in adolescents by enhancing self-control and alleviating psychological emptiness. Relevant interventions should integrate physical activities to improve adolescents’ self-management abilities, satisfy their psychological needs, and lay a foundation for the prevention and treatment of this addictive behavior.
