The Internet Gaming Disorder Scale - Short Form (IGDS9-SF) assesses the severity, harmful effects and/or consequences of excessive online and offline gaming. Its conciseness and theoretical foundations on current diagnostic criteria of gaming disorders make it a useful resource for clinical and screening settings.
To describe the process of cross-cultural adaptation of the IGDS9-SF to the Brazilian context.
The cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, back-translation, pre-test and elaboration of the final version. Content validity assessment was conducted by a multidisciplinary committee of experts and consisted of both a quantitative analysis (calculation of content validity coefficients - CVC) and a qualitative analysis (assessment of the experts' comments and suggestions). The pre-test sample consisted of 30 gamers with variable sociodemographic characteristics.
The cross-cultural adaptation of the scale followed the proposed protocol, and the CVC was satisfactory (≥ 0.83) for all the structures and equivalences assessed. Most of the suggestions made by the experts were accepted (mainly adjustments and language standardization). The gamers who participated in the pre-test judged the scale easy to understand and did not suggest changes.
The Brazilian version of the IGDS9-SF showed adequate content validity and is available for researchers and clinicians, as well as for the investigation of additional psychometric characteristics.
互联网游戏障碍量表-短式（IGDS9-SF）评估过度线上和线下游戏的严重程度、有害影响和/或后果。它的简洁性和对游戏障碍当前诊断标准的理论基础，使其成为临床和筛查环境的有用资源。
描述将 IGDS9-SF 跨文化适应到巴西情境的过程。
跨文化适应包括以下步骤：仪器的独立翻译、综合版本、回译、预测试和最终版本的阐述。内容效度评估由一个多学科专家委员会进行，包括定量分析（内容效度系数的计算 - CVC）和定性分析（评估专家的意见和建议）。预测试样本由 30 名具有不同社会人口统计学特征的游戏者组成。
该量表的跨文化适应遵循了既定的方案，所有评估的结构和等价物的 CVC 均令人满意（≥0.83）。专家提出的大多数建议都被采纳（主要是调整和语言标准化）。参与预测试的游戏者认为该量表易于理解，并未提出更改建议。
巴西版的 IGDS9-SF 显示出足够的内容效度，可供研究人员和临床医生使用，也可用于进一步的心理测量特征研究。
