  Abstract: Objective To analyze the influencing factors of medical college students’ intention to adopt mental health popular science videos, provide theoretical guidance for improving users’ adoption efficiency of such information and promoting mental health popular science work, and offer practical references for enhancing medical students’ mental health literacy. Methods I By integrating the core theoretical contents of the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Information Adoption Model (IAM), a health information adoption behavior model was constructed from five dimensions: performance expectation, effort expectation, facilitating conditions, information quality, and source credibility. Questionnaires were distributed offline, and structural equation modeling was used to verify research hypotheses and analyze the paths of influencing factors. Results A total of 507 valid questionnaires were recovered, with an effective rate of 73.37%. Douyin was the preferred viewing platform (response rate 38.07%, penetration rate 82.45%). Reliability and validity analysis showed that the internal consistency, convergent validity, and discriminant validity of each dimension met the standards; the model fit was good (CMIN/DF=1.909, RMSEA=0.042, CFI=0.98, TLI=0.976, PNFI=0.805). Path analysis indicated that source credibility, information quality, performance expectation, facilitating conditions, and effort expectation all had a significant positive impact on adoption intention (P<0.05). Conclusions Effort expectation has the strongest impact on medical students’ intention to adopt mental health popular science videos. The popular science effect can be improved from three aspects: content creation (low threshold, high value, strong scientificity), communication strategies (optimizing reach relying on high-penetration platforms), and source construction (balancing professionalism and affability).
