Background and aims Since the inclusion of Internet Gaming Disorder (IGD) in the latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a tentative disorder, a few psychometric screening instruments have been developed to assess IGD, including the 9-item Internet Gaming Disorder Scale - Short-Form (IGDS9-SF) - a short, valid, and reliable instrument. Methods Due to the lack of research on IGD in Slovenia, this study aimed to examine the psychometric properties of the IGDS9-SF in addition to investigating the prevalence rates of IGD in a nationally representative sample of eighth graders from Slovenia (N = 1,071). Results The IGDS9-SF underwent rigorous psychometric scrutiny in terms of validity and reliability. Construct validation was investigated with confirmatory factor analysis to examine the factorial structure of the IGDS9-SF and a unidimensional structure appeared to fit the data well. Concurrent and criterion validation were also investigated by examining the association between IGD and relevant psychosocial and game-related measures, which warranted these forms of validity. In terms of reliability, the Slovenian version IGDS9-SF obtained excellent results regarding its internal consistency at different levels, and the test appears to be a valid and reliable instrument to assess IGD among Slovenian youth. Finally, the prevalence rates of IGD were found to be around 2.5% in the whole sample and 3.1% among gamers. Discussion and conclusion Taken together, these results illustrate the suitability of the IGDS9-SF and warrants further research on IGD in Slovenia.
背景与目的 自互联网游戏障碍（IGD）在最新版（第五版）《精神疾病诊断与统计手册》（DSM - 5）中被列为一种暂定疾病以来，已经开发了一些心理测量筛查工具来评估IGD，其中包括9项互联网游戏障碍量表简版（IGDS9 - SF）——一种简短、有效且可靠的工具。方法 由于斯洛文尼亚缺乏关于IGD的研究，本研究旨在检验IGDS9 - SF的心理测量特性，并调查斯洛文尼亚八年级学生全国代表性样本（N = 1071）中IGD的患病率。结果 IGDS9 - SF在效度和信度方面接受了严格的心理测量审查。通过验证性因素分析对结构效度进行了研究，以检验IGDS9 - SF的因子结构，单维结构似乎与数据拟合良好。同时效度和效标效度也通过检验IGD与相关心理社会及游戏相关测量之间的关联进行了研究，这证实了这些效度形式。在信度方面，斯洛文尼亚版IGDS9 - SF在不同水平上的内部一致性取得了优异结果，该测试似乎是评估斯洛文尼亚青少年中IGD的有效且可靠的工具。最后，发现整个样本中IGD的患病率约为2.5%，游戏玩家中为3.1%。讨论与结论 综上所述，这些结果说明了IGDS9 - SF的适用性，并为在斯洛文尼亚进一步研究IGD提供了依据。
