Social exclusion and mobile phone addiction in college students:chain mediating role of rumination and executive function
Objective To explore the relationship between social exclusion,rumination,executive function and mobile phone addiction among college students.Methods From November to December 2023,a total of 516 college students were investigated by social exclusion questionnaire for undergraduate,rumina-tive responses scale,the Geurten-questionnaire of executive functioning in Chinese college students and mo-bile phone addiction tendency scale.SPSS 26.0 statistical software was used for common method bias test,descriptive statistics,correlation analysis,and PROCESS 3.5 macro program was used to test the mediation effect.Results Social exclusion(31.21±12.69),rumination(42.85±12.38),executive function(71.46±9.41),and college students'mobile phone addiction tendency(43.53±11.74)were all significant-ly and positively correlated with each other(r=0.299-0.500,all P＜0.01).The direct effect of social exclu-sion on mobile phone addiction was significant(effect size=0.138,95％CI=0.048-0.228),accounting for 37.91％(0.138/0.364)of the total effect.Rumination had a mediating effect between social exclusion and mobile phone addiction(effect size=0.053,95％CI=0.001-0.112),accounting for 14.56％(0.053/0.364)of the total effect.Executive function mediates the relationship between social exclusion and mobile phone addiction(effect size=0.137,95％CI=0.091-0.188),accounting for 37.64％(0.137/0.364)of the total effect.Rumination and executive function has a chain mediating effect between social exclusion and mo-bile phone addiction(effect size=0.036,95％CI=0.016-0.061),accounting for 9.89％(0.036/0.364)of the total effect.Conclusion Social exclusion can directly affect mobile phone addiction in college students and can also influence mobile phone addiction in college students through the independent mediating effects of rumination and executive function,as well as the chain mediating effect of rumination and executive function.
