Short-form video platforms as a source of ankylosing spondylitis information: a cross-sectional content analysis

Although AS-related short videos are predominantly produced by physicians, the overall quality remains suboptimal. Information quality appears to influence certain user behaviors, such as content saving, but does not consistently translate into higher overall engagement. These findings highlight the limitations of using engagement metrics as proxies for content quality. Users should prioritize content from verified medical professionals, and platforms may consider integrating quality-oriented indicators and improving certification systems to enhance health information dissemination.
