As smartphone use is increasing within the middle-aged population, society should pay closer attention to the mental health problems associated with smartphone addiction. This study examines the possibility that depression, anxiety, and ADHD can be interpreted not only as negative aspects, but also as positive aspects, in an addiction-related individual. We used habitual and addictive smartphone behavior as the dependent variables; anxiety, ADHD, depression, and habitual smartphone use as the independent variables; and self-control as a moderating variable. Depression and ADHD in smartphone users were found to be associated with higher levels of addictive smartphone use. Anxiety was having negative effect on addictive smartphone use. However, habitual smartphone use didn't significantly affect addictive smartphone use. Further analysis indicated that depression, anxiety, and ADHD have mediating effects on habitual smartphone use. This study confirmed that psychological factors in adults, as well as habitual/addictive smartphone use and self-control, significantly influence smartphone overdependence.

The purpose of this study was to examine whether a temporal relationship would develop between the overuse/addictive use of mobile phones and depression in adolescents. For this study, we used the 4-year longitudinal data (2004-2007, Study 1, which measured the overuse of mobile phones and depression) and the 2-year longitudinal data (2010-2011, Study 2, which measured the addictive use of mobile phones and depression) of the Korea Youth Panel study. In addition, the study explored gender differences with respect to the above mentioned relationship. Autoregressive cross-lagged modeling was carried out, along with a multiple group analysis across genders. The findings showed that the overuse/addictive use of mobile phones and depression in adolescents had a significant effect on the future selves of these adolescents over time. Moreover, the overuse/addictive use of mobile phones had a significant influence on subsequent depression, rather than vice versa. This means that as the overuse/addictive use of mobile phones by adolescents increases, their depression intensifies later on; however, as depression among adolescents intensifies, the overuse/addictive use of mobile phones by adolescents' does not increase. Further, the study showed there were significant gender differences in the longitudinal relationship between the overuse/addictive use of mobile phones and depression. Study 1 shows that, prior to the release of smartphones, the overuse of mobile phones had a definite effect on the depression of only males. However, Study 2 shows that, after the release of smartphones, the effect of the addictive use of mobile phones on depression in females was greater than that in males.

Objective : This study aims to investigate the relationship between addictive mobile phone use and post-traumatic stress disorder (PTSD) symptoms in bullies who experienced school violence. Methods : The study subjects consisted of 97 adolescents in The Foundation for Preventing Youth Violence after school violence. The participants conducted self-report questionnaire for addictive mobile phone use and Impacted Event Scale-revised-Korean version (IES-R-K). Partial correlation and multiple logistic regressions were performed. Results : The scores related to addictive mobile phone use were correlated with total score (r=0.21, p=0.04), avoidance score (r=0.21, p=0.04) and intrusive score (r=0.26, p=0.01) related to PTSD symptoms on the IES-R-K. Intrusive score related to PTSD symptoms on the IES-R-K were significant risk factor for addictive mobile phone use (O.R=1.25, 95% CI=1.12-1.39). Conclusion : This data supports that PTSD intrusive symptoms could be predictable factor of addictive mobile phone use. An appropriate intervention about PTSD symptoms might play a useful role in preventing addictive mobile phone use in bullies of school violence.

This study was to identify the correlation between dry eye syndrome, upper extremity pain, depression and addictive smart phone use among college students. Data were collected from 286 college students using a self-report questionnaire. 15.0% of participants have an addictive smart phone use. There were significant differences by dry eye syndrome(t=-4.38, p<.001), neck pain(t=-2.60, p<.05) and depression(t=-4.15, p<.001) according to the addictive smart phone use. Dry eye syndrome(r=.332, p<.001), neck pain(r=.143, p<.05), hand pain(r=.138, p<.05) and depression(r=.402, p<.001) were positively related to addictive smart phone use. Strategies to diminish depression, and to prevent dry eye syndrome and neck pain in college students will be an important intervention component to prevent addictive smart phone use and health problems in future studies.

This study verified theoretical model to explain adolescents' addictive use of smartphone. I used the data of 679 middle and high school students among 2013 internet addiction survey of National Information Society Agency(NIA). This study utilized structural equation modeling analysis to compare a suggestive model and alternative model. According to the final model, higher the satisfaction of family relationship, the addictive use of smartphone and emotional problems of adolescents were reduced. And, higher the addictive use of smartphone, higher the emotional problems of adolescents. Also, family relationship affects emotional problems via addictive use of smartphone. While, in the alternative model, path from amount of smartphone use to addictive use of smartphone was not significant.

This study examined the relationships between self-control and addictive mobile phone use among nursing students. The data was collected through structured questionnaires from 293 students and analyzed using a t-test, ANOVA, Scheffe's test and Pearson's correlation coefficients on SPSS WIN v 18.0 and AMOS v 18.0. The mean scores of self-control and addictive mobile phone use were $3.42{\pm}0.45$ and $2.69{\pm}0.45$, respectively. A statistically significant negative correlation was observed between self-control and addictive mobile phone use (t=-.447, p<.01). In addition, self-control explained 28% of the addictive mobile phone use. Intervention programs to improve self-control should be developed to prevent addictive mobile phone use for nursing students.
