The field of problematic Internet use (PIU) has seen significant academic interest in recent years. In the absence of a universally accepted definition of PIU, a multitude of scales have been developed to evaluate it. Notably, the Generalized Problematic Internet Use Scale 2 (GPIUS-2), formulated on the cognitive-behavioral model by Caplan, emerges as a significant instrument in this domain. This research conducts a systematic review and meta-analysis of the GPIUS-2. The central aim is to assess its internal structure and reliability. This is achieved by a meta-analysis of the Cronbach's alpha and the factorial structure, which is carried out in the framework of the Meta-Analytic Structural Equation Modeling. The results reveal high internal consistency of the GPIUS-2, support the multidimensional nature of the scale, and provide evidence about the presence of a generalized factor supporting the use of a total scale value as indicator of GPIUS. In addition, the study delineates potential areas for future research aimed at further refining the validity of the GPIUS-2.

支持广义问题互联网使用量表 2 的维度和内部一致性：系统评价和荟萃分析。


近年来，问题互联网使用 （PIU） 领域引起了学术界的极大兴趣。在没有普遍接受的 PIU 定义的情况下，已经开发了多种量表来评估它。值得注意的是，由 Caplan 根据认知行为模型制定的广义问题互联网使用量表 2 （GPIUS-2） 成为该领域的重要工具。本研究对 GPIUS-2 进行了系统评价和荟萃分析。中心目标是评估其内部结构和可靠性。这是通过对 Cronbach 的 alpha 和因子结构的元分析来实现的，该分析是在元分析结构方程建模的框架内进行的。结果揭示了 GPIUS-2 的高度内部一致性，支持量表的多维性质，并提供了关于存在支持使用总量表值作为 GPIUS 指标的广义因子的证据。此外，该研究还描绘了未来研究的潜在领域，旨在进一步完善 GPIUS-2 的有效性。
