Objective To explore the relationship and underlying mechanism between personality and mobile phone dependence in junior school students.Methods Five⁃factor personality questionnaire for Middle school students,problematic mobile video gaming scale,school bonding scale and smartphone addiction scale were used to measure in 1075 junior school students.Results Personality is significantly correlated with school bonding and mobile phone dependence.Problematic mobile game use(PMG)partially mediated between conscientiousness,neuroticism,openness and phone dependence,and fully mediated between agreeableness and mobile phone dependence.High school bonding will decrease the predictive effect of PMG on mobile phone dependence.Conclusion Personality of junior high school students is closely related to mobile phone dependence,which is mediated by PMG and moderated by school bonding.
