Gaming Disorder (GD) has been recently added to the eleventh revision of the (ICD-11) by the World Health Organization (WHO), as such, psychometrically sound psychological measures are required to assess this disorder. The objective of this study was to investigate the psychometric properties of the Spanish Gaming Disorder Test (GDT) by assessing its dimensionality, reliability, convergent validity, and associations with other variables of importance through polytomous Item Response Theory (IRT) and Measurement Invariance (MI) analysis across genders. To achieve this, a sample of 538 gamers (42.94% female, mean = 23.29 years, SD = 7.24) was recruited. The results obtained supported a one-factor structure for the Spanish GDT with adequate reliability and convergent validity. Furthermore, satisfactory goodness of fit in the partial credit model (PCM) with more precise scores at high trait levels to assess GD was found, and strict invariance across genders was supported. These findings attest to the suitability of the Spanish GDT for clinical assessment and research on disordered gaming beyond community samples.

游戏障碍（GD）最近被世界卫生组织（WHO）列入《国际疾病分类》第11版（ICD - 11），因此，需要心理测量学上可靠的心理测量方法来评估这种障碍。本研究的目的是通过多分类项目反应理论（IRT）和跨性别测量不变性（MI）分析，评估西班牙游戏障碍测试（GDT）的维度、信度、收敛效度以及与其他重要变量的关联，以研究其心理测量特性。为实现这一目标，招募了538名游戏玩家作为样本（42.94%为女性，平均年龄 = 23.29岁，标准差 = 7.24）。所得结果支持西班牙GDT的单因素结构，具有足够的信度和收敛效度。此外，在部分计分模型（PCM）中发现了良好的拟合优度，在高特质水平上有更精确的分数来评估GD，并且支持跨性别严格不变性。这些发现证明了西班牙GDT适用于临床评估以及对社区样本之外的游戏障碍进行研究。
