This study is a descriptive study to investigate the influence factors on smartphone overdependenceon in male middle school students. A questionnaire survey was conducted on 174 male middle school students about their smartphone overdependence, stress, ego - resilience, and use of smartphone by function. In results, 29.9% (potential risk group 23.6%, high risk group 6.3%) of the male middle school students were the smartphone overdependency risk group. A higher smartphone overdependency was associated with the higher the smartphone usage time per day, the higher the stress level, the higher the grade, and the lower the ego-resilience level. This requires the involvement of appropriate stress coping styles to overcome excessive stress situations. And the development and implementation of an intervention program that increases the level of ego-resilience can be expected to have an effect of controlling the smartphone use time as well as the intervention effect on stress coping.

Internet overdependence has become a public health concern in Korea. It is well known that family and community level efforts could alleviate possible harms from Internet use. However, little research exists regarding smartphone overdependence. This study examines factors affecting smartphone overdependence and, specifically, help-seeking for smartphone overdependence among Korean adolescents. The study is based on parental mediation theory and uses a help-seeking framework. The results indicate that preventative education provided by school and community increases the levels of awareness of both the possible harms from smartphone use and the option of accessing the mental health service, while it was not effective in preventing smartphone overdependence. Parental mediation was a protective factor for smartphone overdependence but was negatively associated with the intention to use the mental health service. In sum, behavioral problems related to smartphone use require multidimensional preventative efforts from both the family and the community. It is suggested that effective preventive education methods are developed for parents and adolescents.
