Some studies have revealed that a substantial proportion of the younger population has engaged in problematic gaming with even infants recently being able to enjoy video games. However, the relationship between the risk for problematic gaming and age at which habitual gaming starts remains unknown. This study therefore investigated this relationship among adolescents.
A survey was conducted at eight public junior high schools across Japan. The questionnaire included items regarding the background, night-time sleep, age at which weekly gaming began, time spent on the Internet and gaming, the Japanese version of Young's Diagnostic Questionnaire, the Ten-Item Internet Gaming Disorder Test (IGDT-10), and others. We analyzed 549 participants who engaged in weekly gaming and have played games during the past year.
Among the participants, 1.8% were suspected to have Internet gaming disorder (IGDT-10 ≥ 5). Bedtime and wake-up time on weekdays and holidays were significantly later among problematic gamers (IGDT-10 ≥ 3) than among normal gamers (IGDT-10 ≤ 2). Onset of weekly gaming before the age of 5 was associated with a significantly higher risk of problematic gaming than onset of weekly gaming after the age of 10.
Our results revealed that the risk for problematic gaming was positively associated with a younger age at which weekly gaming begins. Longitudinal problematic gaming prevention, starting from an early stage, is thus necessary.
一些研究表明，相当一部分年轻人存在游戏成瘾问题，甚至婴儿也能玩视频游戏。然而，游戏成瘾的风险与开始习惯性玩游戏的年龄之间的关系尚不清楚。因此，本研究调查了青少年中的这种关系。
在日本的八所公立初中进行了一项调查。问卷包括背景、夜间睡眠时间、每周开始玩游戏的年龄、上网和玩游戏时间、日本版 Young 诊断问卷、十项网络游戏障碍测试（IGDT-10）等项目。我们分析了 549 名每周玩游戏且在过去一年中玩过游戏的参与者。
在参与者中，有 1.8%的人被怀疑患有网络游戏障碍（IGDT-10≥5）。有问题的游戏玩家（IGDT-10≥3）比正常游戏玩家（IGDT-10≤2）在工作日和节假日的就寝时间和起床时间明显更晚。每周玩游戏的起始年龄在 5 岁之前与每周玩游戏的起始年龄在 10 岁之后相比，与游戏成瘾问题的风险显著升高有关。
我们的研究结果表明，游戏成瘾的风险与每周开始玩游戏的年龄呈正相关。因此，需要从早期开始进行有针对性的游戏成瘾预防。
