The nine-item Problematic Internet Use Questionnaire (PIUQ-9) is a brief self-report screening instrument for problematic internet use. The main objective of the present study was to explore the psychometric properties of the PIUQ-9 among nine different language-based samples of European internet users (Italian, German, French, Polish, Turkish, Hungarian, English, and Greek). The total sample comprised 5,593 internet users (38.1% men), aged between 18 and 87 years ( = 25.81; = 8.61). Via online recruitment, participants completed the PIUQ-9, the Brief Symptom Inventory (BSI) and items about time spent online. Confirmatory factor analysis demonstrated that the bifactor model with one general factor (i.e., general problem) and two-specific factors (i.e., obsession and neglect + control disorder) yielded acceptable or good fit indices in all subsamples except for one. The common variance index in the bifactor model indicated that the general problem factor explained from 57.0 to 76.5% of common variance, which supports the presence of a strong global factor. According to the multiple indicators multiple causes (MIMIC) model, psychiatric symptoms had a moderate-to-strong direct effect on the general problem factor in all subsamples, ranging from β = 0.28 to β = 0.52 supporting the construct validity of the scale. Furthermore, in a majority of the subsamples, time spent online during the weekend had considerably higher effect sizes on the general problem factor than time spent online during weekdays. The present study highlights the appropriate psychometric properties of the PIUQ-9 across a number of European languages and cultures.
九项网络使用问题问卷（PIUQ - 9）是一种用于筛查网络使用问题的简短自评工具。本研究的主要目的是在欧洲九个不同语言群体的互联网用户样本（意大利语、德语、法语、波兰语、土耳其语、匈牙利语、英语和希腊语）中探究PIUQ - 9的心理测量特性。总样本包括5593名互联网用户（男性占38.1%），年龄在18至87岁之间（平均年龄 = 25.81岁；标准差 = 8.61岁）。通过在线招募，参与者完成了PIUQ - 9、简明症状量表（BSI）以及关于上网时间的项目。验证性因素分析表明，具有一个一般因素（即一般问题）和两个特定因素（即痴迷与忽视 + 控制障碍）的双因素模型，在除一个子样本外的所有子样本中都产生了可接受或良好的拟合指数。双因素模型中的共同方差指数表明，一般问题因素解释了57.0%至76.5%的共同方差，这支持了一个强大的全局因素的存在。根据多指标多原因（MIMIC）模型，精神症状在所有子样本中对一般问题因素都有中度到强烈的直接影响，范围从β = 0.28到β = 0.52，支持了该量表的结构效度。此外，在大多数子样本中，周末上网时间对一般问题因素的效应量比工作日上网时间的效应量要高得多。本研究突出了PIUQ - 9在多种欧洲语言和文化中的适当心理测量特性。
