Relationships of personality and lifestyle with mobile phone dependence among female nursing students

To clarify the relationships of personality and lifestyle with mobile phone dependence, defined as an intermittent craving to use a mobile phone or excessive mobile phone use, we administered a self-report questionnaire to 132 female college students attending a nursing school in Osaka, Japan. Results of multiple regression analysis indicated that scores for extroversion and neuroticism were positively related to the score of the Mobile Phone Dependence Questionnaire (MPDQ; Toda, Monden, Kubo, & Morimoto, 2004), while the score for healthy practices was negatively related to that of the MPDQ. These findings suggest that mobile phone dependence in female college students is associated with elevated traits of extroversion and neuroticism, as well as an unhealthy lifestyle.
