Abstract: Objective To explore the relationship between boredom and mobile phone dependence among college students.Methods A total of 418 college students were tested with the Boredom Proneness Scale and the Mobile Phone Addiction Index.Results The scores of all factors of mobile phone dependence in high boring proneness group was obviously higher than those in low boring proneness group(17.97±4.76 vs.14.60±3.88 for uncontrollabilityt=5.84,P<0.001; 14.16±4.10 vs.12.08±4.10 for withdrawalt=3.81,P<0.001; 8.83±2.69 vs.7.50±2.62 for evasiont=3.78,P<0.001; and 5.89±2.18 vs.4.79±1.93 for inefficiencyt=5.50,P<0.001).Mobile phone dependence was significantly and positively correlated with loneliness and monotony; self-control was significantly and negatively correlated with mobile phone dependence; loneliness had significant predictive effect on mobile phone dependence(t=3.567,P<0.01); self-control had significant negatively predictive effect on mobile phone dependence(t=-4.365,P<0.01); and boredom proneness had significantly positive predictive effect on mobile phone dependence(t=6.686,P<0.001).Conclusion All the factors of boredom proneness correlate differently with and could effectively predict mobile phone dependence among college students.
