In order to explore the relationship among positive psychological capital, coping style and
mobile phone dependence of freshmen, and the mediating effect of coping style between them, 310
freshmen were tested with Positive Psychological Capital Scale (PPQ), Simple Coping Style Questionnaire
(SCSQ) and Mobile Phone Dependence Scale (MPAI). A series of analysis operations were carried
out by SPSS, and the results showed that there was a significant positive correlation between positive
psychological capital and coping style (r=0.42, p<0.01), a significant negative correlation between
positive psychological capital and mobile phone dependence (r=-0.28, p<0.01), and a significant negative
correlation between coping style and mobile phone dependence (R =-0.31, p<0.01). Positive psychological
capital can also indirectly predict college freshmen’s mobile phone dependence behavior through coping
style, and coping style plays a partial mediating role between positive psychological capital and mobile
phone dependence behavior, with a mediating effect ratio of 34.74%. The results of this study reveal
that the level of positive psychological capital can directly affect freshmen’s mobile phone dependence
behavior, and can also indirectly affect their mobile phone dependence behavior through coping styles.
