At‐risk internet addiction and related factors among senior high school teachers in Japan based on a Nationwide survey

Abstract

AbstractBackgroundInternet addiction (IA) has been drawing attention to mental health. However, few reports have been found on the related factors of at‐risk IA among regular workers by a nationwide survey. The study aimed to evaluate the characteristics of at‐risk IA and identify related factors among senior high school teachers in Japan.MethodsThis survey was a cross‐sectional survey of high schools across Japan in 2017. There were 3189 teachers (2088 males and 1098 female) who participated in this survey. The questionnaire asked about their devices, both the time and the activities of using their internet, and sociodemographic factors. IA was measured by the internet addiction test (IAT) by which 40–79 points were classified as at‐risk IA, and more as IA. We compared the related factors of at‐risk IA and non‐IA using descriptive analysis and multivariable regression analysis.ResultsThe rates of IA and at‐risk IA were 0.09% (n = 3) and 6.91% (n = 220), respectively. At‐risk IA was positively associated with activities on the internet for gaming, entertainment, net‐surfing, and younger ages. In addition, the at‐risk IA group had a longer time spent on the internet than the non‐IA group.ConclusionsAround 7% of high school teachers are at‐risk IA in this survey, though they have regular work. Our results suggest that at‐risk IA may be reinforced not only by the active internet use such as gaming, but also by purposeless behaviors, such as net‐surfing. Managing time on the internet may support preventing at‐risk IA among senior high school teachers.
