Purpose : To investigate the degree of smartphone addiction among health-related college students, and to compare and analyze the effect of the degree of addiction on attention control and interpersonal support. Methods : 184 people who voluntarily participated and agreed to fill out the questionnaire were randomly sampled. The smartphone self-diagnosis scale was used to measure the degree of smartphone addiction, and the Attentional Control Questionnaire (ACQ) was used as a tool to measure the degree of attention control. In addition, the Interpersonal Support Evaluation List (ISEL) was used to measure the degree of interpersonal support. Results : In comparison of the degree of smartphone addiction according to the general characteristics of the subjects, there was no significant difference according to religion, major, and grade, but there was a significant difference in gender and daily use time of smartphones (p <.05). There was a significant difference in the degree of attention control according to the level of smartphone addiction (high risk, potential risk, general user group) (p <.05), but there was no significant difference in the degree of interpersonal support. Conclusion : The degree of smartphone addiction was relatively higher for women than for men, and users who used it for a long time per day were more addicted. It also showed that attention control was further reduced in highly addictive users.

This paper is about an analysis of the result of the survey which is how the use of smartphone affects the creative personality, focused on 4th and 6th grade in Elementary school, by smartphone addiction self-diagnosis and creative personality test. As a result of the analysis, 6th graders were influenced by their possession of smartphone and the degree of one's smartphone addiction on their creative personality. However, the usage period of smartphone did not turn out to affect their creative personality. In addition, none of the factors above, related to students' smartphone usage, influenced the creative personality of 4th graders. Particularly, there was a negative correlation between the level of students' smartphone addiction and the creative personality and it was found that whether the students own a smartphone or not played a crucial role in creative personality rather than the usage period of smartphone. Therefore, students should be properly educated how to use smartphone appropriately and to prevent them from smartphone addiction in order to improve creative personality which is one of the core competences in 21st century.

Smartphone addiction has become more serious than internet addiction since people can download and run numerous applications with smartphones even without internet connection. However, smartphone addiction is not sufficiently dealt with in current studies. The S-scale method developed by Korea National Information Society Agency involves so many questions that respondents are likely to avoid the diagnosis itself. Moreover, since S-scale is determined by the total score of responded items without taking into account of demographic variables, it is difficult to get an accurate result. Therefore, in this paper, we have extracted important factors from all data, which affect smartphone addiction, including demographic variables. Then we classified the selected items with a neural network. The result of a comparative analysis with backpropagation learning algorithm and multiclass support vector machine shows that learning rate is slightly higher in multiclass SVM. Since multiclass SVM suggested in this paper is highly adaptable to rapid changes of data, we expect that it will lead to a more accurate self-diagnosis of smartphone addiction.

Purpose : VDT (visual display terminal syndrome) can affect individuals who monitor or who work or play using video screens, including those of smartphones. In general, headache symptoms from overuse of these screens can appear due to eye fatigue, muscle pain in the joints of wrists or fingers, and muscle pain in the neck or shoulders. Many studies in the literature have supported standards that seek to prevent these symptoms. The incidence of musculoskeletal diseases caused by the use of smartphones is expected to increase rapidly, particularly among children and young adults, and these diseases are expected to develop into a societal problem. Therefore, in this study we investigate whether tension headaches that develop from smartphone usage can affect forward neck posture, neck pain, and quality of life. Methods : A total of 93 students from University participated in this study. We divided participants into two groups, those with tension headaches (n = 25) and those without (n = 68) and took forward neck measurements. Headaches were classified according to criteria from the International Headache Society and involved bilateral headache position, quality of pressing or tightening pain, mild or moderate pain intensity, and none due to daily physical activity. We surveyed participants using the smartphone addiction diagnosis questionnaire, the Neck Disability Index (NDI), the Headache Impact Test (HIT-6), and the Quality of Life Questionnaire. Results : Although we found no significant differences in tension headaches due to smartphone addiction diagnosis (p = 0.25), SF-36 life quality assessment (p = 0.06), and cranio-vertebral angle (p = 0.07), we found significant differences from the HIT-6 and the NDI (p <.05). Conclusion : Tension headaches are not correlated with smartphone addiction, quality of life, and forward neck angle but do have a correlation with the degree of cervical dysfunction and the effects of the headaches.

The purpose of this study is to verify the causal relationship between the smartphone addiction proneness, mental health, and impulsiveness of high school students in Korea. 804 first and second year high school students participated in the survey that included the Smartphone addiction scale, Korean Brief Mental Diagnosis Exam - the highest 25% of total score (Addictive SmartPhone Use Group : ASPUG 213 persons), the lowest 25% of total score(Non-Addictive SmartPhone Use Group : NASPUG 204 persons), BIS-II Impulsiveness Scale and additional questions asking for demographical characteristics. The outcomes of this study were as follows. First, sex, grade of high school, academic accomplishment, student's satisfaction with school life, monthly allowance, the level of parental respect, having a opposite sex friend were related to smartphone addiction and impulsiveness. Second, ASPUG had worse mental health and impulsiveness than NASPUG, and the difference was statistically significant. Third, Students showed higher levels of mental health 9 subareas - anxiety, depression, phobic anxiety, Somatization, obsessive compulsive, interpersonal sensitivity, hostility, Paranoid ideation, Psychosis as their smartphone use increased.

Objectives : The current study investigated the risk of smartphone addiction among children and adolescents with or without attention-deficit hyperactivity disorder (ADHD), risk of depression, anxiety, and self-esteem using the Smartphone Addiction Scale Proneness, Kovac's Children's Depression Inventory, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale, commonly used in clinical medicine. Methods : Ninety five students with ADHD who visited psychiatry outpatient clinics completed the questionnaire. At the same time, 592 middle and high school students living in a similar area regardless of ADHD diagnosis, completed the questionnaire as control subjects. Results : Overall, 40.0% of 95 ADHD and 12.8% of 592 control subjects were classified as the smartphone addiction proneness group, 26.3% of the ADHD subjects and 8.3% of the control group were classified as the depression group, and 32.6% of the ADHD subjects and 16.2% of the control group were classified as the anxiety group. Significant differences were observed between the two groups. Conclusion : The results of this study suggest that ADHD subjects are more prone to smartphone addiction, becoming depressed or anxious than those in the control group. From this study, we could suggest that students with ADHD are more easily affected by smartphone addiction than normal control subjects. In addition, we might understand how some psychiatric problems like depression, anxiety, and low self-esteem are related to ADHD and smartphone addiction.

Purpose: This study was conducted to find out the mediated effects of smartphone overindulgence in the relationship between attention and spinal health of adolescents and to find out how cognitive strength moderates these relationships. Design: Cross-sectional study. Methods: All subjects measured attention, cognition strength, spinal angle, and smartphone overindulgence by measuring the ratio of SMR and mid-beta power to the power of the brain wave, amplitude variation of Cognitive Gamma-Peak, forward slope angle of the cervical spine, and the scale of diagnosis of smartphone addiction. Results: As a result, it shows a significant correlation between Attention, spinal angle, cognitive strength, and smartphone overindulgence(p<.05). In addition, attention was significantly mediated on the spinal angle through smartphone overindulgence(p<.001), and cognitive strength was significantly mediated in relation to smartphone overindulgence and spinal angle(p<.05). Conclusion: This result indicates that the mediation effect of overindulgence of a Smartphone is mediated according to its cognitive strength in relation to its effect of attention on the spine angle.
