Perceived stress and life satisfaction: the mediating roles of sport commitment and mobile phone addiction

This study aimed to investigate the relationship between perceived stress and life satisfaction under the influence of mobile phone addiction and sport commitment. Participants were recruited from eight universities located in six Chinese cities, naming Chongqing, Maoming, Nanjing, Suzhou, Shijiazhuang, and Zhengzhou. The sample consisted of 575 participants enrolled in Chinese universities, with 309 (53.7%) being female students. The mediation model was tested under the structural equation modeling framework using Mplus. Results showed that (1) perceived stress had a direct and negative impact on life satisfaction, and it also had indirect effects through the two mediators; (2) perceived stress positively predicted mobile phone addiction, which, in turn, negatively impacted life satisfaction; (3) perceived stress negatively predicted sport commitment, which, in turn, positively impacted life satisfaction. By emphasizing the mediating roles of mobile phone addiction and sport commitment, our findings highlight the importance of addressing these factors in interventions aimed at encouraging college students' well-being. Implications for intervention design to promoter health among university students should take into account the mediating roles of mobile phone addiction and sport commitment.
