The study tested the psychometric properties of two Chinese version Internet Gaming Disorder scales (IGDSs): a dichotomous IGDS with yes/no type of response and a polytomous IGDS with a 0-5 Likert-type response.
The reliability and validity of two scales were tested separately, among two population-based samples of Chinese adolescents and adults (351 for dichotomous IGDS and 378 for polytomous IGDS). The diagnostic accuracy of the dichotomous IGDS was assessed in an independent sample of 114 gamers (56 disordered gamers and 58 average gamers) using Receiver Operating Characteristic (ROC) analysis.
The results demonstrated good internal consistency (α = 0.80 and α = 0.89) and test-retest reliability (r = 0.83 and r = 0.84) for both scales. Both scales showed sound validity, as indicated by significant correlations with measurements of internet addiction, aggression, impulsivity, craving for gaming and time spent playing games. Factor analysis demonstrated that both Chinese IGDSs have a similar single-component structure to the original scales. The ROC analysis indicated an excellent diagnostic accuracy of the dichotomous IGDS. When apply the five or more cutoff points, the prevalence of IGD was 7.41% in the population-based sample.
This study demonstrated robust psychometric properties of the Chinese version dichotomous IGDS and polytomous IGDS, and suggests that these scales are valid tools that suitable for clinical and research purposes.
本研究测试了两个中文版网络成瘾障碍量表（IGDS）的心理测量特性：一个是采用是/否回答类型的二分法IGDS，另一个是采用0-5李克特式回答的多分类IGDS。
在两个基于人群的中国青少年和成人样本中（二分法IGDS有351人，多分类IGDS有378人）分别测试了这两个量表的信度和效度。使用受试者工作特征（ROC）分析在一个由114名游戏玩家（56名成瘾游戏玩家和58名普通游戏玩家）组成的独立样本中评估二分法IGDS的诊断准确性。
结果表明两个量表都具有良好的内部一致性（α = 0.80和α = 0.89）和重测信度（r = 0.83和r = 0.84）。两个量表都显示出良好的效度，这体现在与网络成瘾、攻击性、冲动性、游戏渴望程度以及游戏时长测量结果之间存在显著相关性。因素分析表明两个中文版IGDS与原始量表具有相似的单成分结构。ROC分析表明二分法IGDS具有出色的诊断准确性。当采用五个或更多的临界值时，基于人群的样本中IGD的患病率为7.41%。
本研究证明了中文版二分法IGDS和多分类IGDS具有稳健的心理测量特性，并表明这些量表是适用于临床和研究目的的有效工具。
