The Problematic Social Media Use Scale (PSMUS) is a promising self-report measure assessing problematic use of social media among adolescents and adults. However, data concerning its psychometrics are still scant, and adaptation in Eastern cultures is missing. This study aimed to test the factorial structure, internal consistency, and external validity of the Chinese version of the PSMUS in a sample of 672 adults (31% males) aged between 18 and 58. A series of confirmatory factor analyses supported the bifactor structure of the PSMUS, including a general factor and five specific independent components, namely preference for online social interactions, mood regulation, cognitive preoccupation, compulsive use, and negative outcomes. Hierarchical Omega supported the presence of a general factor, and also ancillary indexes suggested that the questionnaire is not strictly unidimensional. Subsequent structural equation modeling testing the incremental contribution of each PSMUS facet in predicting negative emotional states showed that, above and beyond the general factor, only one of the five dimensions (i.e., negative outcomes) significantly links to our criterion measure further support the use of an overall PSMU score. Moreover, results support the external validity of the questionnaire, given its positive association with depression, anxiety, and stress scores. The Chinese version of the PSMUS is a psychometric sound instrument to assess the level of PSMU in adults. Future research may evaluate the cross-cultural validity of the bifactor model and its associations with other assessment methods.
问题性社交媒体使用量表（PSMUS）是一种很有前景的自评工具，用于评估青少年和成年人中存在问题的社交媒体使用情况。然而，关于其心理测量学的数据仍然很少，并且在东方文化中的适应性研究尚属空白。本研究旨在对672名年龄在18至58岁之间的成年人（31%为男性）样本进行中文版PSMUS的因子结构、内部一致性和外部效度测试。一系列验证性因子分析支持了PSMUS的双因子结构，包括一个一般因子和五个特定的独立成分，即对在线社交互动的偏好、情绪调节、认知专注、强迫性使用和负面结果。分层欧米伽系数支持一般因子的存在，并且辅助指标表明该问卷并非严格的单维问卷。随后的结构方程模型测试了PSMUS每个方面在预测负面情绪状态方面的增量贡献，结果表明，除了一般因子之外，五个维度中只有一个维度（即负面结果）与我们的标准测量指标有显著关联，这进一步支持了使用PSMUS的总体得分。此外，鉴于该问卷与抑郁、焦虑和压力得分呈正相关，结果支持了该问卷的外部效度。中文版PSMUS是一种心理测量学上可靠的工具，可用于评估成年人的问题性社交媒体使用水平。未来的研究可以评估双因子模型的跨文化效度及其与其他评估方法的关联。
