In recent years, there have been frequent reports of gaming disorder in China, with more focus on young people. We developed and psychometrically tested a Gaming Disorder screening scale (i.e., Gaming Disorder Screening Scale - GDSS) for Chinese adolescents and young adults, based on the existing scales and diagnostic criteria, but also considering the development status of China.
For testing content and criterion validity, 1747 participants competed the GDSS and the Internet Addiction Test (IAT). After 15 days, 400 participants were retested with the scales for to assess test-retest reliability. Besides, 200 game players were interviewed for a diagnosis of gaming disorder.
The Cronbach's alpha coefficient on the GDSS was 0.93. The test-retest coefficient of 0.79. Principal components analysis identified three factors accounting for 62.4% of the variance; behavior, functioning, cognition and emotion. Confirmatory factor analysis showed a good model fit to the data (χ /df = 5.581; RMSEA =0.074; TLI = 0.916, CFI = 0.928). The overall model fit was significantly good in the measurement invariance tested across genders and different age groups. Based on the clinical interview, the screening cut-off point was determined to be ≥47 (sensitivity 41.4%, specificity 82.3%).
The GDSS demonstrated good reliability and validity aspects for screening online gaming disorder among Chinese adolescents and young adults.
近年来，中国频繁报道游戏障碍，且更多关注于年轻人。我们基于现有的量表和诊断标准，并考虑到中国的发展状况，为中国青少年和年轻成年人开发并心理测量学检验了一个游戏障碍筛查量表（即游戏障碍筛查量表-GDSS）。
为了检验内容和效标效度，1747 名参与者完成了 GDSS 和网络成瘾测试（IAT）。15 天后，400 名参与者用这些量表进行重测，以评估测试-重测信度。此外，对 200 名游戏玩家进行了访谈以诊断游戏障碍。
GDSS 的克朗巴赫 α 系数为 0.93。重测信度系数为 0.79。主成分分析确定了三个因素，占方差的 62.4%；行为、功能、认知和情绪。验证性因子分析表明，数据拟合良好（χ/df=5.581；RMSEA=0.074；TLI=0.916，CFI=0.928）。在跨性别和不同年龄组的测量不变性检验中，整体模型拟合度显著良好。根据临床访谈，确定筛查截止值为≥47（灵敏度 41.4%，特异性 82.3%）。
GDSS 在中国青少年和年轻成年人中筛查在线游戏障碍具有良好的信度和效度。
