Problematic gaming has become a major health issue in children and adolescents resulting in the need for targeted valid and reliable screening instruments. This study aimed to explore the psychometric properties and criterion validity of the widely used 9-item Internet Gaming Disorder Scale (IGDS) in young gamers.
Three independent samples were drawn from socio-demographically representative cross-sectional telephone surveys collected in the years 2016 (N = 762), 2017 (N = 777), and 2018 (N = 784) and analyzed separately.
The IGDS revealed psychometric properties suitable for screening in large samples. Cronbach's alpha was 0.563, 0.724, and 0.778. The unidimensionality assumption was challenged. At-risk and pathological gamers compared to normal gamers reported longer digital media use and more emotional symptoms and hyperactivity/inattention with clinical relevance to medium effect sizes. The comparison of at-risk and pathological gamers indicated a partial distinction between the two problematic gaming groups.
The IGDS could be shown to be an overall suitable and valid tool to identify pathological gamers in childhood and adolescence according to the DSM-5 criteria on a population level. However, the polythetic structure limits comparability with the recent ICD-11 criteria. At-risk gamers appeared as a heterogeneous group warranting more research.
问题性游戏已成为儿童和青少年的主要健康问题，因此需要有针对性的有效且可靠的筛选工具。本研究旨在探讨广泛使用的 9 项网络成瘾障碍量表（IGDS）在年轻游戏玩家中的心理测量特性和效标效度。
从 2016 年（N = 762）、2017 年（N = 777）和 2018 年（N = 784）的具有代表性的横断面电话调查中抽取了三个独立的样本，并分别进行分析。
IGDS 显示出适合在大样本中进行筛查的心理测量特性。克朗巴赫的α系数分别为 0.563、0.724 和 0.778。单维性假设受到挑战。与正常玩家相比，有风险和病态的游戏玩家报告说，数字媒体的使用时间更长，情绪症状和多动/注意力不集中的情况更多，这与中等效应大小的临床相关。有风险和病态游戏玩家之间的比较表明，这两个有问题的游戏群体之间存在部分区别。
根据 DSM-5 标准，IGDS 可以在人群水平上被证明是一种总体上合适且有效的工具，可用于识别儿童和青少年中的病态游戏玩家。然而，多因素结构限制了与最近的 ICD-11 标准的可比性。有风险的游戏玩家似乎是一个异质群体，需要进一步研究。
