: The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) includes the diagnostic criteria for Internet gaming disorder (IGD). This study evaluated (1) the screening, diagnostic, and prevalence-estimated cutoff points of the Chen Internet Addiction Scale-Gaming Version (CIAS-G) for IGD in the DSM-5; and (2) the differences in the CIAS-G and subscale scores among individuals with IGD, regular gamers (RGs), and other control subjects. We recruited 69 participants with IGD, 69 RGs, and 69 healthy participants based on diagnostic interviews conducted by a psychiatrist according to DSM-5 IGD criteria. All participants completed the CIAS-G and were assessed using the clinical global impression scale. The optimal screening and diagnostic cutoff points were 68 or more (sensitivity, 97.1%; specificity, 76.8%) and 72 or more (sensitivity, 85.5%; specificity, 87.0%) for IGD based on DSM-5 criteria, respectively. The 76 or more cutoff point had the highest number needed to misdiagnose and was the optimal prevalence estimated cutoff point. The screening cutoff point could be used to identify individuals with IGD for further diagnostic interviewing to confirm the diagnosis in the clinical setting or for two-stage epidemiological evaluation. The diagnostic cutoff point provides a provisional diagnosis of IGD when diagnostic interviewing is unavailable. The prevalence-estimated cutoff point could be used to estimate the prevalence of IGD in large-scale epidemiological investigations when further diagnostic interviewing is impractical. The clinical and epidemiological utility of CIAS-G warrants further study.
：《精神障碍诊断与统计手册》第五版（DSM-5）包括了网络成瘾障碍（IGD）的诊断标准。本研究评估了：（1）Chen 网络成瘾量表-游戏版（CIAS-G）在 DSM-5 中的 IGD 筛查、诊断和患病率估计截断值；（2）IGD 患者、常规游戏者（RGs）和其他对照组之间 CIAS-G 和子量表得分的差异。我们根据 DSM-5 IGD 标准，通过精神科医生进行的诊断访谈，招募了 69 名 IGD 患者、69 名 RG 患者和 69 名健康参与者。所有参与者都完成了 CIAS-G 量表，并使用临床总体印象量表进行评估。根据 DSM-5 标准，最佳的筛查和诊断截断值分别为 68 或更高（敏感性为 97.1%，特异性为 76.8%）和 72 或更高（敏感性为 85.5%，特异性为 87.0%）。76 或更高的截断值误诊所需人数最多，是最佳的患病率估计截断值。筛查截断值可用于识别有 IGD 倾向的个体，以便在临床环境中进行进一步的诊断访谈以确认诊断，或用于两阶段的流行病学评估。在无法进行诊断访谈时，诊断截断值可提供 IGD 的临时诊断。患病率估计截断值可用于在进一步的诊断访谈不切实际的大规模流行病学调查中估计 IGD 的患病率。CIAS-G 的临床和流行病学效用值得进一步研究。
