This study aimed to survey the impact of smartphone overuse on upper extremity pain, anxiety, depression, and interpersonal relationships among college students. Subjects completed a structured questionnaire consisting of the Smartphone Addiction Inventory, the Musculoskeletal Symptom Checklist, the State-Trait Anxiety Inventory, the Beck Depression Inventory-II, and the Relationship Change Scale from May to June 2012. We analyzed the survey data from 525 responses, excluding unreturned or incomplete surveys. Data were analyzed using the $x^2$ test and t-test to determine the differences in smartphone overuse and its impact on upper extremity pain, anxiety, depression, and interpersonal relationships between two groups: the overuse and normal use groups. Moreover, Pearson's correlation coefficient was used to examine the correlation between smartphone overuse and upper extremity pain, anxiety, depression, and interpersonal relationships. The results placed 62 people (11.8%) in the smartphone overuse group. The extent of smartphone overuse was more severe among female than male college students, and longer time spent using smartphones per day was directly related to smartphone overuse. The smartphone overuse group evidenced higher shoulder pain than the normal use group did, but no differences were found in other sites of the upper extremities. State anxiety, trait anxiety, and depression were higher in the smartphone overuse group than in the normal use group. Subjects with a higher extent of smartphone overuse experienced increased state-anxiety, trait-anxiety, and depression. Moreover, subjects with higher state-anxiety, trait-anxiety, and depression scores were more likely to have poor interpersonal relationships. Therefore, early screening for smartphone overuse should be evaluated, because it can be useful in developing addiction prevention programs to improve posture, stress coping, positive mental health, and effective interpersonal relationships.

Purpose: This study aimed to identify parental factors associated with smartphone overuse in preschoolers. Methods: A systematic review was conducted according to PRISMA guidelines. Relevant studies published in peer-reviewed journals from 2009 to June 2019 were identified through systematic search in 10 electronic databases (PubMed, CINAHL, Cochrane Central, EMBASE, Web of Science, NDSL, KISS, KMbase, KoreaMed, and RISS). Standardized effect sizes were calculated to quantify the associations of parental factors with smartphone overuse in preschoolers using meta-analysis. Results: A total of 30 cross-sectional studies involving 7,943 participants met the inclusion criteria. The following were negatively correlated with smartphone overuse in preschoolers: mother's parenting self-efficacy (r=-.35), mother-child attachment (r=-.28), mother's positive parenting behavior (r=-.28), mother's positive parenting attitude (r=-.25), and father's parenting involvement (r=-.15). Further, maternal factors such as smartphone addiction tendency (r=.41), parenting stress (r=.40), negative parenting behavior (r=.35), negative parenting attitude (r=.14), smartphone usage time (r=.26), employment status (r=.18), and age (r=.12) were positively correlated with smartphone overuse in preschoolers. Conclusion: Several parental factors influence smartphone overuse in preschoolers. These findings emphasize the need to assess and enhance the parental factors identified in this study to prevent smartphone overuse in preschoolers. Accordingly, we recommend the development of preventive interventions to strengthen parent-related protective factors and mitigate risk factors.

Purpose: This study was aimed to examine the effects of smartphone overuse and individual factors including age, relationship with friends, satisfaction with school life, and time of smartphone usage on perceived cognitive functions, fatigue, and daytime sleepiness among college students. Methods: Three-hundred college students were recruited after confirming the absence of major depressive symptoms. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression. Results: Smartphone overuse commonly explained the variance in perceived cognitive functions, fatigue, and daytime sleepiness, after controlling for individual factors. In addition, satisfaction with school life was significantly related with better effectiveness of cognitive functions while being male, having good relationships with friends and satisfaction with school life were relatively associated with a lower level of fatigue. Conclusion: The findings of this study revealed that the overuse of smartphone can serve as a psycho-cognitive burden leading to ineffective functioning in daily living. Students who are female and have issues regarding school life and friendship may be a high risk group for experiencing psycho-cognitive dysfunction associated with smartphone overuse. Further investigation is needed to develop effective interventions to improve psycho-cognitive health associated with the excessive use of smartphone in young adults.

This study was conducted to ascertain the mediating effects of aggression in high school students' relationship with smartphone overuse and cyberbullying. Data were collected from 328 high school students in K city using self-report questionnaire. The collected data were analyzed using SPSS 22.0 and AMOS 22.0. The results show that cyberbullying has a positive correlation with smatrphone overuse(r=.321, p<.001) and aggression(r=.397, p<.001). Smartphone overuse had a direct effect on aggression(${\beta}=.195$, p=.014) and aggression had a direct effect on cyberbullying(${\beta}=.260$, p=.007). In addition, the mediation effects of aggression on the relationship between smartphone overuse and cyberbullying were confirmed(${\beta}=.051$, p=.007). In order to reduce cyberbullying in high school students, it will be necessary to develop cyber ethical awareness education programs to reduce aggression as well as regulations on excessive use of smartphones.

This study is a descriptive correlation that attempts to determine the mediating effect of self-efficacy on the relationship between university life stress and smartphone overuse. A total of 201 university students attending universities within Jeonbuk were evaluated using self-reported questionnaires from April 10 to May 10, 2017. The demographic characteristics, university life stress, self-efficacy, and smartphone overuse were analyzed by descriptive statistical analysis. The difference in smartphone overuse by demographic characteristics was analyzed by t-tests and ANOVA with Scheffe's post hoc test, and the correlation between variables was evaluated by Pearson's correlation coefficient. The mediating effect of self-efficacy was the 3-step multiple regression statistics of Baron and Kenny, and the statistical significance of the mediating effect was analyzed by the Sobel test. Self-efficacy had a partial mediating effect in the relationship between university life stress and smartphone overuse. In addition, the risk of smartphone overuse increased among university freshmen, with many using smartphones for more than 4 or 6 hours per day. The result of this study are expected to be useful as basic data for the development of a program to prevent excessive smartphone use by university students.

purpose: This study aims to understand the relationship between stress in college life, vulnerability to depression, and smartphone overuse among undergraduate students majoring in public health. Methods: The subjects of the study were 320 students who were selected through convenience sampling from the department of emergency medical technology, physical therapy, and public health and administration attending G University in Gwangju. The study was carried out from October 22 to 26, 2012. For final analysis, 266 copies were used. Statistical analysis was done using SPSS WIN 12.0. Results: Excessive use of smartphones had a negative effect on stress in college life and vulnerability to depression. The stress of college life had an effect on students' sense of value, their friends of the same sex, and job. Depressive vulnerability had an effect on a students' dependency. Conclusion: For the prevention of smartphone overuse, programs to prevent college life stress and vulnerability to depression should be developed. Counselling programs for the groups should be made available to the students.
