After applying inclusion and exclusion criteria, the remaining videos were evaluated by a third assessor in a double-blind manner using the Video Information and Quality Index (VIQI), the Global Quality Score(GQS)and the modified DISCERN (mDISCERN) scales to assess scientific accuracy, safety and educational value. Platform differences were analyzed with non-parametric tests and correlation analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The final sample comprised 80 YouTube and 77 Bilibili videos. Median views, likes, and comments were markedly higher on Bilibili (\n                      <jats:italic>p\u202f&amp;lt;<\/jats:italic>\n                      \u202f0.05). Verified accounts supplied 43.75% of YouTube content but only 28.57% of Bilibili content; licensed mental-health professionals appeared in fewer than 6% of videos on either platform. YouTube favoured television-style or documentary formats, whereas Bilibili relied heavily on single-speaker narratives and animations. YouTube outperformed Bilibili on overall VIQI, GQS, and mDISCERN scores (\n                      <jats:italic>p\u202f&amp;lt;<\/jats:italic>\n                      \u202f0.01). On Bilibili, high user engagement correlated moderately to strongly with quality, yet absolute quality scores remained low.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Platform architecture, not popularity, drives content quality. YouTube\u2019s longer, institution-produced videos set the benchmark, whereas Bilibili trades scientific rigor for real-time chat and high engagement. Both sites remain short of licensed professionals. To prevent digital platforms from amplifying student anxiety, we recommend (a) embedding a quality-weighted algorithmic boost and (b) a sustained \u201cverified expert + student co-creation\u201d pipeline that disseminates evidence-based content at scale.<\/jats:p>\n
