Multifactorial study of mobile phone dependence in medical students: Relationship to health-related lifestyle, Type A behavior, and depressive state

その他

We investigated factors contributing to mobile phone dependence. To 139 medical students, we administered a self-reporting questionnaire de- signed to evaluate mobile phone dependence, health-related lifestyle, patterns of behavior, and depressive state. Multivariate logistic regression analysis revealed that scores for poor health- related lifestyle, Type A behavior pattern, and presence of depression are independently as- sociated with degree of mobile phone depend- ency. These findings suggest that persons with an unhealthy lifestyle, Type A behavior traits, or depression might benefit from mobile phone use guidance.
