Objectives: To estimate the prevalence of internet gaming disorder (IGD) and associated risk factors in a sample of secondary and postsecondary students from a public federal institution of higher education (Instituto Federal de Educação, Ciência e Tecnologia) in Southern Brazil. Methods: The study included a sociodemographic questionnaire, the Beck Depression Inventory (BDI), Self-Report Questionnaire (SRQ-20), Pittsburgh Sleep Quality Index (PSQI-BR), the Mini-Social Phobia Inventory (Mini-SPIN), and the Game Addiction Scale (GAS). Finally, IGD was measured with the Brazilian version of the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), which has been psychometrically validated in this population. Results: Overall, 38.2% (n=212) of the sample exhibited IGD symptoms, with 18.2% (n=101) being classed as at-risk gamers. Regression analysis found IGD to be associated with male gender, severe depressive symptoms, poor sleep quality, increased time spent gaming, and total free time spent gaming (p < 0.001). Conclusions: The prevalence of IGD in this sample was relatively high, and associated risk factors found were similar to those previously reported in the literature. Further studies investigating the epidemiology of IGD in Brazilian samples are warranted to better understand treatment needs and inform preventive measures in this population.

网络游戏障碍的患病率和危险因素

目标：评估来自巴西南部公立联邦高等教育机构 (Instituto Federal de Educação, Ciência e Tecnologia) 的中学和中学后学生样本中网络游戏障碍 (IGD) 的患病率和相关风险因素。方法：该研究包括社会人口调查问卷、贝克抑郁量表 (BDI)、自我报告问卷 (SRQ-20)、匹兹堡睡眠质量指数 (PSQI-BR)、迷你社交恐惧症量表 (Mini-SPIN) 和游戏成瘾量表（GAS）。最后，IGD 是用巴西版的互联网游戏障碍量表 - 简表 (IGDS9-SF) 测量的，该量表已在该人群中进行了心理测量验证。结果：总体而言，38.2% (n=212) 的样本表现出 IGD 症状，其中 18.2% (n=101) 被归类为高危游戏玩家。回归分析发现 IGD 与男性、严重的抑郁症状、睡眠质量差、游戏时间增加和游戏总空闲时间相关（p < 0.001）。结论：该样本中 IGD 的患病率相对较高，发现的相关危险因素与之前文献报道的相似。需要进一步研究巴西样本中 IGD 的流行病学，以更好地了解该人群的治疗需求并告知预防措施。发现的相关危险因素与先前在文献中报道的相似。需要进一步研究巴西样本中 IGD 的流行病学，以更好地了解该人群的治疗需求并告知预防措施。发现的相关危险因素与先前在文献中报道的相似。需要进一步研究巴西样本中 IGD 的流行病学，以更好地了解该人群的治疗需求并告知预防措施。
