Gaming disorder (GD) is a growing public health issue requiring reliable screening and diagnostic tools. A commonly used tool for assessing GD is the Gaming Disorder Test (GDT). The GDT assesses GD based on International Classification of Diseases 11th Revision (ICD-11) criteria; however, its psychometric testing has been conducted across studies but yet snythesized. This meta-analysis aimed to synthesize psychometric data regarding the GDT globally. Adhering to pre-registration, a comprehensive search across databases identified 17 eligible studies (n=22,000) in 14 languages reporting on the psychometric properties of the GDT, especially its Cronbach's alpha. The pooled Cronbach's alpha was 0.86 (95% CI: 0.83-0.89), indicating excellent internal consistency. Although significant heterogeneity was observed (I= 98.54%), prediction intervals suggested true outcomes likely shared a positive direction. No moderating effects were found regarding sample characteristics, study quality, or geographical location. The meta-analysis provides robust and quantitative evidence supporting the internal consistency of the GDT across diverse populations. Moreover, qualitative synthesis indicates that the GDT has strong psychometric properties without risk of bias across the analyzed studies, indicating the GDT's ability to assess GD globally. However, the heterogeneity suggests cautious interpretation of the reliability estimates.
游戏障碍（GD）是一个日益严重的公共卫生问题，需要可靠的筛查和诊断工具。一种常用的评估游戏障碍的工具是游戏障碍测试（GDT）。GDT根据《国际疾病分类》第11版（ICD - 11）标准评估游戏障碍；然而，其心理测量测试已在多项研究中进行，但尚未进行综合分析。这项荟萃分析旨在综合全球范围内关于GDT的心理测量数据。按照预先注册的要求，对多个数据库进行全面检索，确定了17项符合条件的研究（n = 22,000），这些研究以14种语言报告了GDT的心理测量特性，特别是其克朗巴哈系数。合并后的克朗巴哈系数为0.86（95%置信区间：0.83 - 0.89），表明具有出色的内部一致性。尽管观察到显著的异质性（I² = 98.54%），但预测区间表明真实结果可能具有相同的正向趋势。在样本特征、研究质量或地理位置方面未发现调节效应。该荟萃分析提供了有力的定量证据，支持GDT在不同人群中的内部一致性。此外，定性综合分析表明，GDT具有强大的心理测量特性，在所分析的研究中不存在偏倚风险，这表明GDT能够在全球范围内评估游戏障碍。然而，异质性表明对可靠性估计的解释应谨慎。
