Abstract：
In 2019, Gaming Disorder (GD) was acknowledged as an official diagnosis by the World Health Organization. The Gaming Disorder Test (GDT) is the most widely used tool to measure GD; however, due to its novelty, various measurement properties are still unexplored, and the number of validated language variants is still limited. The present study is the first to assess the psychometric properties of the Czech version of the GDT. Further, it focuses on its temporal prevalence and stability, gaming genre invariance, and criterion validity. A large-scale sample of adult Czech gamers collected at two points within nine months was analysed - T1 N = 5356; T2 N = 6077; longitudinal sample N = 1430. Confirmatory factor analysis (CFA), structural equation modelling (SEM), and multigroup CFA were employed to assess the measurement invariance. The study confirmed the one-factor structure of the GDT and showed that it is invariant across preferred gaming genres and the time of data collection. It showed a negative relationship with life satisfaction and a positive relationship with anxiety, even when controlling for their mutual relationships. The prevalence in the longitudinal sample was equal to or below 1.9% in each wave, but only 0.5% in the longitudinal sample (hence n = 7 participants fulfilled in both waves the criteria for GD). The study suggests that the Czech version of the GDT has good psychometric properties, including temporal stability and invariance across gaming genres, so it is suitable for the survey type and epidemiological investigation of the ICD-11\'s Gaming Disorder.
摘要：
2019年，游戏障碍（GD）被世界卫生组织认可为官方诊断。游戏障碍测试(GDT)是最广泛使用的测量GD的工具;然而,由于它的新颖性，各种测量特性仍未探索，并且验证的语言变体的数量仍然有限。本研究是第一个评估捷克版GDT的心理测量特性的研究。Further,它侧重于其时间普遍性和稳定性，游戏类型不变性，和标准有效性。分析了九个月内在两个点收集的成年捷克游戏玩家的大规模样本-T1N=5356；T2N=6077；纵向样本N=1430。验证性因素分析(CFA)结构方程模型(SEM)，采用多组CFA评估测量不变性。该研究证实了GDT的单因素结构，并表明它在首选游戏类型和数据收集时间上是不变的。它与生活满意度呈负相关，与焦虑呈正相关，即使在控制他们的相互关系时。纵向样本中的患病率在每个波中等于或低于1.9％，但在纵向样本中只有0.5%(因此n=7名参与者在两个波中都满足GD的标准)。研究表明，捷克版的GDT具有良好的心理测量特性，包括时间稳定性和游戏类型的不变性，因此适用于ICD-11游戏障碍的调查类型和流行病学调查。
