Objectives The purpose of this study was to investigate the relationships among circadian types, depressive mood and internet addiction and to identify the mediating effect of depressive mood between circadian types and internet addiction in Korean College Students. Methods A total of 2632 participants completed questionnaires, which included the Korean translation of the Composite Scale of Morningness (CSM), the Patient Health Questionnaire (PHQ-9), and the Korean version of the Internet Addiction Test (KIAT). Statistical analyses were done using correlation analysis, analysis of covariance and multiple linear regression. Results The CSM score was negatively associated with the PHQ-9 score (r = -0.226, p < 0.001) and the KIAT score (r = -0.218, p < 0.001). The eveningness group showed higher scores in depressive mood and internet addiction than the morningness group (p < 0.001). Depressive mood showed a partial mediating effect between circadian types and internet addiction (${\beta}=0.255$, p < 0.001). Conclusions Internet addiction was associated with circadian types and depressive mood. These results suggest that depression and circadian rhythm management would contribute to the prevention of internet addiction.

As a result of regression analysis, the Internet addiction according to family types was a negative relationship and significant. Family types were positively related to self-esteem. As for interpersonal relations, family types were significant as a positive relationship. On the other hand, maladjusted behaviors were proved that they have a negative relationship with family types like the Internet addiction.

An internet addiction measure(Park et al., 2001) and an asocial behavior measure(K. J. Lee, 1997) were administered to 232 6th-grade students. Statistical analyses were by mean-difference scores and t-test. Results showed that all aspects of internet addiction(preoccupation, compulsive use, relapse, tolerance/dependence and impediments in daily life) were related to both the inner asocial behaviors of depression, social withdrawal and over-anxiety and the external asocial behaviors of aggressiveness, delinquency and hyperactivity. The only exception was that tolerance/dependence was not related to delinquency. Boys addicted to the internet were more socially withdrawn, aggressive, delinquent and hyperactive than girls. From the results, it can be suggested that internet education should be carried out from the elementary educational level.

Purpose: This study aimed to investigate the effects of various factors on smartphone addiction according to types of risk groups among middle school students. Methods: Data of 223 students were collected from February 1st to 22nd of 2020. The collected data were analyzed through t-test, χ² test, correlaton coefficients, and multiple regression analysis. The smartphone addiction scale was used to classify the participants into two groups; 18.8% (n=42) of the total respondents were categorized as the addiction risk group and 81.2% (n=181) were categorized as the general population group. Results: The factors associated with the students in the high risk group were grade (t=3.89, p=.036) and religion (F=3.79, p=.044). In the high risk group, psychological anxiety (β=.39, p=.005) and relapse of internet addiction (β=.38, p=.006) explained 46.0% of smartphone addiction, while in the normal risk group, relapse of internet addiction (β=.42, p<.001), psychological anxiety (β=.22, p=.004), tolerance of internet addiction (β=.17, p=.007), and academic stress (β=.14, p=.027) explained 51.0% of smartphone addiction. Conclusion: In order to prevent smartphone addiction in middle school students, a more specific nursing intervention is needed that can reduce psychological anxiety and relapse of internet addiction. It is clear that urgent measures need to be taken for the highly addicted students such as academic counseling.
