An important step in Internet addiction research is to develop standardized instruments for assessing Internet addiction-related symptoms. The Compulsive Internet Use Scale (CIUS) is a promising brief questionnaire. The aim of this study was to examine the factor structure of a German version of the CIUS with confirmatory factor analysis in a general population sample. In addition, the best fitting structure was tested for factorial invariance across sex, age, education level, and weekly Internet use. We used a weighted general population sample (N=8,132) of 14-64 years olds spending at least 1 hour online for private purposes per typical working or weekend day. Findings include that a one-factor model was found to fit well. It was invariant across sex, age, education level, and weekly Internet use. The findings support the validity of the CIUS as a short screening instrument.
网络成瘾研究的一个重要步骤是开发用于评估与网络成瘾相关症状的标准化工具。强迫性网络使用量表（CIUS）是一种很有前途的简短问卷。本研究的目的是使用验证性因素分析，在一般人群样本中检验 CIUS 的德语文本的因子结构。此外，还针对性别的、年龄的、教育水平的和每周上网时间的因子不变性检验了最佳拟合结构。我们使用了加权的一般人群样本（N=8132），年龄在 14-64 岁之间，每个典型工作日或周末至少有 1 小时用于私人目的上网。研究结果包括，一个单因素模型拟合得很好。它在性别、年龄、教育水平和每周上网时间上是不变的。研究结果支持 CIUS 作为一种简短的筛查工具的有效性。
