The relationship between uploader identity and the quality and reliability of depression-related Chinese short videos on TikTok and Bilibili.

BACKGROUND: The depression has become a major challenge to global public health. Short video platforms like TikTok and Bilibili have become important channels for disseminating information about depression, but the quality and reliability have not been evaluated. OBJECTIVE: This study aims to evaluate the quality and credibility of depression-related short videos on TikTok and Bilibili, focusing on the differences in the identity of the uploader and its impact on the reliability of the content. METHODS: Using the keyword "depression" to collect 150 videos on TikTok and Bilibili. This research institute involves Chinese videos and Chinese uploaders. Divided The identity of uploaders into depressed patients, mental health educators, mental health practitioners and non-professional sharers. Use the Global Quality Score, modified DISCERN and JAMA benchmarking to evaluate. RESULTS: Videos published by mental health practitioners have the highest JAMA scores and user participation indicators. The mDISCERN reliability score of non-professional sharing is the lowest. The content published by depressed patients is reliable, but the coverage and interaction are limited. CONCLUSION: The depression information constitutes a multi-party ecosystem, but the credibility depends on the identity of the uploader. Content from professional sources is still the most reliable. The platform should strengthen the authentication mechanism. Users should critically evaluate the source of content cautiously.
