Abstract The objectives of this study were to evaluate the psychometric properties, measurement invariance and mean differences in relation to the genders and age categories of the 6-item PIUQ-SF in a non-clinical sample of Nigerian adolescents (n = 1222; Mage = 15.77; Range = 12–18). There were 622 (50.9%) females. Most (79.1%) were in the middle adolescent age bracket. The respondents completed the PIUQ-SF-6 in addition to the Hospital Anxiety and Depression Scale (HADS) and the Drug Abuse Screening Test (DAST). We applied confirmatory factor analysis (CFA) to examine the fit indices of the three-factor a priori PIUQ-SF-6 model described in literature. Measurement invariances across genders and age categories were evaluated with nested multiple-group CFA (MGCFA). The three-dimensional model of the PIUQ-SF-6 appears to satisfactorily evaluate problematic usage of the internet among Nigerian adolescents (CFI = 0.985, SRMR = 0.0214, RMSEA = 0.055/90% CI = 0.036–0.077). The internal consistencies (α) of the PIUQ-SF-6 and its three subscales were modestly satisfactory. The concurrent validity of this model was also modestly supported via significant correlations with the other study measures. MGCFA supported the configural, metric and scalar measurement invariances of the PIUQ-SF-6 across genders and age categories. Males and those in the late adolescent age category have significant higher scores on the total PIUQ-SF-6. The PIUQ-SF-6 will be a useful instrument for the quantitative evaluation and comparisons of problematic usage of the internet among Nigerian adolescents.

互联网使用问题调查表（简短表格6）（PIUQ-SF-6）：尼日利亚青少年的性别，年龄组的维度，有效性，可靠性，度量不变性和均值差异

摘要这项研究的目的是评估尼日利亚非临床样本（n = 1222；法师= =）中6项PIUQ-SF的性别和年龄类别的心理特征，测量不变性和均值差异。 15.77；范围= 12–18）。有622名（50.9％）女性。大多数（79.1％）处于青少年中期年龄段。除了医院焦虑和抑郁量表（HADS）和药物滥用筛查测试（DAST）外，受访者还完成了PIUQ-SF-6。我们应用验证性因子分析（CFA）来检查文献中描述的三因子先验PIUQ-SF-6模型的拟合指数。使用嵌套的多组CFA（MGCFA）评估了不同性别和年龄类别的测量不变性。PIUQ-SF-6的三维模型似乎可以令人满意地评估尼日利亚青少年的互联网使用问题（CFI = 0.985，SRMR = 0.0214，RMSEA = 0.055 / 90％CI = 0.036-0.077）。PIUQ-SF-6及其三个分量表的内部一致性（α）中等令人满意。通过与其他研究指标的显着相关性，该模型的并行有效性也得到了适度的支持。MGCFA支持PIUQ-SF-6在性别和年龄类别之间的配置，度量和标量度量不变性。男性和青春期后期类别的人在PIUQ-SF-6总评分中的得分更高。PIUQ-SF-6将是定量评估和比较尼日利亚青少年互联网使用问题的有用工具。
