Abstract: Objective To understand the mediating role of time management disposition between nursing interns' sense of meaning in life and mobile phone dependence,and to provide reference for improving the mobile phone dependence of nursing interns. Methods From October 2022 to January 2023,252 nursing interns were selected from two tertiary Grade A hospitals in Xi'an City.They were investigated with the general information questionnaire,the sense of life scale,the mobile phone dependence scale and the time management disposition scale,and the data were analyzed. Results The scores of sense of meaning of life,mobile phone dependence,and time management disposition of nursing interns in two tertiary Grade A hospitals in Xi'an City were （51.38±7.88）,（34.76±9.32）,（154.41±21.41）points,respectively.The sense of meaning of life was negatively correlated with mobile phone dependence（r=-0.196,P<0.01）,and time management disposition was negatively correlated with mobile phone dependence（r=-0.248,P<0.01）.Time management disposition had a complete mediating effect between nursing interns' sense of meaning in life and mobile phone dependence（β=-0.17,P<0.05）,and the mediation effect accounted for 68%. Conclusion Time management disposition is the mediating variable between the sense of meaning of life and mobile phone dependence of nursing interns in two tertiary Grade A hospitals in Xi'an City.Nursing educators should actively carry out relevant training to strengthen the sense of meaning of life and time management ability of nursing interns,so as to improve the mobile phone dependence of nursing interns.
