Serial Multiple Mediation of the Correlation Between Internet Addiction and Depression by Social Support and Sleep Quality of College Students During the COVID-19 Epidemic

Objective@#This cross-sectional study explores the serial multiple mediation of the correlation between internet addiction and depression by social support and sleep quality of college students during the COVID-19 epidemic. @*Methods@#We enrolled 2,688 students from a certain university in Wuhu, China. Questionnaire measures of internet addiction, social support, sleep quality, depression and background characteristics were obtained. @*Results@#The prevalence of depression, among 2,688 college students (median age [IQR]=20.49 [20.0, 21.0] years) was 30.6%. 32.4% of the students had the tendency of internet addiction, among which the proportion of mild, moderate and severe were 29.8%, 2.5% and 0.1%, respectively. In our normal internet users and internet addiction group, the incidence of depression was 22.6% and 47.2%, respectively. The findings indicated that internet addiction was directly related to college students’ depression and indirectly predicted students’ depression via the mediator of social support and sleep quality. The mediation effect of social support and sleep quality on the pathway from internet addiction to depression was 41.97% (direct effect: standardized estimate=0.177; total indirect effect: standardized estimate= 0.128). The proposed model fit the data well. @*Conclusion@#Social support and sleep quality may continuously mediate the link between internet addiction and depression. Therefore, the stronger the degree of internet addiction, the lower the individual’s sense of social support and the worse the quality of sleep, which will ultimately the higher the degree of depression. We recommend strengthening monitoring of internet use during the COVID-19 epidemic, increasing social support and improving sleep quality, so as to reduce the risk of depression for college students.

Application of ‘incorrect cases’in medical statistics teaching / 中华医学教育探索杂志

Objective To evaluate the application effect of‘incorrect cases’in medical statis-tics teaching. Methods The junior students (n=307)of clinical medicine were selected as research subjects by random cluster sampling. They were divided into the teaching improving group (n=151) who accepted case teaching and control group (n=156)who accepted traditional teaching. At the end of the term,the teaching effect was surveyed by questionnaires and compared between the two groups. Measurement data was analyzed by t test,enumeration data by χ2 test and ranked data by rank sum test. Results Students' interests of medical statistics and understanding the importance of the course in teaching improving group were significantly higher than that in control group (Z=-2.375,P=0.018;Z=-2.971,P=0.003). The proportion of students with learning difficulties in teaching improving group was obviously lower than that in control group (Z=-2.488,P=0.013). The satisfaction with theory and practical teaching in teaching improving group (84.10% and 88.74%,respectively)was significantly higher that in control group (73.08%and 71.79%,respectively)(χ2=5.530,P=0.013;χ2=13.841,P<0.001). Although no difference was observed in the test score between the two groups (t=1.230,P=0.220),knowledge of parameter estimation,hypothesis testing and science research design in teach-ing improving group was significantly higher than that in control group (χ2=6.829,P=0.009;χ2=5.835, P=0.016). Conclusions Application of ‘incorrect cases’in medical statistics teaching could arouse students' learning interests and improve clinical medical students' comprehensive analy sis ability of medical statistics.
