Relationship between mobile phone addiction and sleep quality among medical students based on structural equation modeling research on the relationship between depression
Objective To explore the relationship among mobile phone addiction,sleep quality and depression in medical students using structural equation modeling,and examine the mediating role of sleep quality between mobile phone addiction and depression.Methods A total of 2088 college students were selected using cluster random sampling from a medical college in Xinjiang Uygur Autonomous Region from September to October 2021,and a questionnaire sur-vey was conducted using the Mobile Phone Addiction Index(MPAI),Pittsburgh Sleep Quality Index(PSQI),and Self Rating Depression Scale.Results The detection rate of mobile phone addiction among medical students was 30.75%,of which 59.50%(382/642)had sleep quality problems and 60.44%(388/642)had obvious depression.The scores of sleep quality,falling asleep time,sleep disorder,hypnotics,daytime dysfunction,PSQI and depression between the mobile phone addiction group and the non mobile phone addiction group were statistically significant(P<0.05).The structural equation model shows that all fitting indicators meet the standards,and mobile phone addiction has a direct positive effect on depression(β=0.34,P<0.05),mobile phone addiction can indirectly affect depression through sleep quality(χ2/df=2.477,RMSEA=0.027,GFI=0.997,AGFI=0.992,NFI=0.996).Conclusions Mobile phone addiction can directly affect depression and indirectly affect depression through sleep quality.
