Internet gaming disorder (IGD) is emerging as an important source of behavioral addiction in young people globally.
The aim of this study was to assess addiction to internet gaming in medical students using a self designed research instrument.
We conducted a cross-sectional study and enrolled 264 male and 160 female MBBS students ( = 424) in Delhi, India. The study instruments included: a 2-item Internet gaming screening questionnaire (IGSQ), a 14-item self-designed Internet gaming addiction scale (IGAS) to measure addiction-like behavior associated with multiplayer Internet gaming, and the Pittsburgh Sleep Quality Index to measure sleep quality.
After preliminary screening, 91 male and 6 female participants were found to be multiplayer Internet gamers, and were further assessed using the 14-item IGAS. The Cronbach's alpha of the IGAS was 0.879. Principal component analysis revealed a three-component IGAS structure based on eigenvalue cutoff (>1), loading score >0.4, and inspection of the scree-plot that explained 66.71% of the total variance. The IGAS score and the average weekly gaming time of the participants showed a moderate positive correlation ( = 0.45, < 0.001). Only 17 (4.0%) participants reported agreement/strong agreement across ≥5 domains of addiction. The mean (standard deviation) IGAS score was significantly higher in the participants reporting poor sleep quality (PQSI > 6) ( = 0.047).
IGD has low prevalence among medical students, and the problem is negligible among female students. The 14-item IGAS, in conjunction with the 2-item IGSQ, are reliable and valid tools for the assessment of IGD.
网络游戏障碍（IGD）正成为全球年轻人行为成瘾的一个重要来源。
本研究旨在使用自行设计的研究工具评估医学生对网络游戏的成瘾情况。
我们进行了一项横断面研究，纳入了印度德里的264名男性和160名女性医学学士学生（n = 424）。研究工具包括：一份2项的网络游戏筛查问卷（IGSQ）、一份自行设计的14项网络游戏成瘾量表（IGAS），用于测量与多人网络游戏相关的成瘾样行为，以及匹兹堡睡眠质量指数，用于测量睡眠质量。
经过初步筛查，发现91名男性和6名女性参与者为多人网络游戏玩家，并使用14项IGAS进行进一步评估。IGAS的Cronbach's α系数为0.879。主成分分析基于特征值截断（>1）、载荷得分>0.4以及碎石图检验，揭示了一个三成分的IGAS结构，该结构解释了总方差的66.71%。参与者的IGAS得分与平均每周游戏时间呈中度正相关（r = 0.45，P < 0.001）。只有17名（4.0%）参与者报告在≥5个成瘾领域达成一致/强烈同意。报告睡眠质量差（PQSI > 6）的参与者的平均（标准差）IGAS得分显著更高（P = 0.047）。
IGD在医学生中的患病率较低，且该问题在女学生中可忽略不计。14项IGAS与2项IGSQ相结合，是评估IGD的可靠且有效的工具。
