[Purpose/significance] False short videos integrate multimodal content such as images, text, and audio,with their varying content structures potentially influencing the dissemination of short videos by manipulating user trust. Investigating the impact of multimodal content structure manipulation of false short videos on users′ sharing inten⁃sion aids in identifying false short videos and enhances platforms′ capacity to govern false information. [Method/pro⁃cess] Drawing upon SOR theory, this study constructed a research model in the context of false short videos: "informa⁃tion structure-perceived credibility-user attention-user sharing intention". Data was collected through a mixed-meth⁃ods approach combining questionnaires, eye-tracking experiments, and semi-structured interviews. [Result/conclu⁃sion] Users directed greater attention towards text areas than image areas, whilst exhibiting greater variability in atten⁃
tion distribution within image areas. Based on the structural manipulation of false short videos, this study found that the primary-secondary and parallel relationships exert a significant positive influence on perceived accuracy and consis⁃tency, while causal relationships exert a significant negative influence on perceived accuracy. Perceived accuracy ex⁃erts a significant positive influence on text fixation counts, image fixation counts, and image fixation duration. Text fixa⁃tion counts, image fixation counts, and image fixation duration exert a significant positive influence on users′ sharing in⁃tension.
