Abstract

Aim: The Internet Gaming Disorder Scale is a 9-item screening instrument developed based on the diagnostic criteria for Internet Gaming Disorder (IGD) in the DSM-5. This study aimed to examine the reliability and validity of the Internet Gaming Disorder Scale for children (IGDS-C) in Japanese clinical and nonclinical populations.

Methods: The study included clinical outpatients aged 9-29 with problematic game use and nonclinical adolescents aged 12-18 who played online games at least once a week. Reliability was examined by calculating internal consistency and test-retest reliability. Validity was assessed using Spearman's correlation and Confirmatory Factor Analysis (CFA).

Results: A total of 746 participants (93 clinical, 653 nonclinical) were eligible for statistical analysis. Reliability results revealed acceptable internal consistency (Cronbach's α = 0.87) and test-retest reliability (intraclass correlation coefficient = 0.62). CFA results (Comparative Fit Index = 0.92, Tucker-Lewis Index = 0.90, root mean square error of approximation = 0.10, standardized root mean square residual = 0.05, factor loadings = 0.59-0.71) and significant correlations with the GAMES test, psychological distress, and gaming hours verified the validity of the IGDS-C.

Conclusion: The study verified the reliability and validity of the IGDS-C in Japanese clinical and nonclinical participants, suggesting that it generally reflects the severity of IGD well.

日本版儿童网络游戏障碍量表（IGDS-C）的信度和效度。

目的：网络游戏障碍量表是基于DSM-5中网络游戏障碍（IGD）的诊断标准开发的9项筛查工具。本研究旨在检验儿童网络游戏障碍量表（IGDS-C）在日本临床和非临床人群中的信度和效度。方法：研究对象包括9-29岁有游戏使用问题的临床门诊患者和12-18岁每周至少玩一次网络游戏的非临床青少年。通过计算内部一致性和重测信度来检验信度。采用Spearman相关和验证性因子分析（CFA）评估效度。结果：共有746名参与者（93名临床，653名非临床）符合统计分析。信度结果显示可接受的内部一致性（Cronbach's α = 0.87）和重测信度（类内相关系数= 0.62）。CFA结果（比较拟合指数= 0.92，Tucker-Lewis指数= 0.90，近似均方根误差= 0.10，标准化均方根残差= 0.05，因子负荷= 0.59-0.71）以及与GAMES测试、心理困扰和游戏时间的显著相关性验证了IGDS-C的有效性。结论：本研究验证了IGDS-C在日本临床和非临床参与者中的信度和效度，表明IGDS-C总体上较好地反映了IGD的严重程度。
