Although YouTube is driving change in the news and information environment and earning a reputation as an alternative media, there is a lack of research examining what determines people’s reputational judgments on YouTube’s political channels. Based on in-depth interviews with 32 experts and empirical findings from 380 adults, this research identified factors that impact YouTube users’ reputation perception of political channels and developed a scale. The results showed that the Political YouTube Channel Reputation (PYCR) scale comprises four distinctive dimensions: news credibility, political ideology, user-oriented communication, and quality management. The reliability and validity of the scale were assessed, using exploratory and confirmatory analyses and construct validity. The PYCR scale has a variety of potential applications for users, political influencers, and YouTube, and it can serve as a theoretical framework for future empirical research in this novel and emerging area.

尽管YouTube推动着新闻和信息环境的变化，并赢得了替代媒体的声誉，但仍缺乏研究来研究决定人们对YouTube政治渠道的声誉判断的研究。根据对32位专家的深入访谈和380位成年人的经验发现，这项研究确定了影响YouTube用户对政治渠道声誉认知的因素，并制定了一个量表。结果表明，政治YouTube频道声誉（PYCR）量表包括四个与众不同的维度：新闻可信度，政治意识形态，面向用户的交流和质量管理。使用探索性和确认性分析以及结构效度对量表的信度和效度进行了评估。PYCR秤对用户具有各种潜在的应用，
