This study aims to develop and validate a checklist for IGD symptoms of Chinese adolescents based on the fifth edition of the diagnostic and statistical manual of mental disorders (DISCA). We recruited 2144 secondary school students who reported that they had played Internet games in the past 12 months in two large cities of China. The 9 item of DISCA were all significantly and positively correlated and the scale reliability was satisfactory. The unidimensional structure of the scale was confirmed by Confirmatory Factor Analysis (CFA), χ/df = 246.18/27, CFI = .95, RMSEA = .06. Measurement invariance across gender and city groups was confirmed by Multiple-group CFA. Criterion validity was demonstrated by the significant positive associations between DISCA score and self-identified IGD, loss of control regarding time spent on Internet gaming, time spent on playing Internet games, depression, and suicidal ideation. DISCA is a brief, reliable, and validated assessment to measure adolescent IGD.
本研究旨在基于《精神障碍诊断与统计手册》第五版（DISCA），为中国青少年的互联网游戏障碍症状开发和验证一个检查表。我们招募了 2144 名在过去 12 个月中报告曾玩过网络游戏的中学生，来自中国的两个大城市。DISCA 的 9 个项目均与总分呈显著正相关，且量表信度令人满意。验证性因子分析（CFA）证实了量表的单维结构，χ/df = 246.18/27，CFI = 0.95，RMSEA = 0.06。多组 CFA 证实了性别和城市组间的测量不变性。DISCA 评分与自我认同的互联网游戏障碍、对上网游戏时间的失控感、上网游戏时间、抑郁和自杀意念之间存在显著正相关，证明了其效标效度。DISCA 是一种简短、可靠和有效的评估工具，用于测量青少年的互联网游戏障碍。
