BREAST CANCER
To present the influence of the three variables mentioned above, the video production team, consisting of proficient short video producers and science popularization workers with medical backgrounds, created three groups of videos on three topics: (1) hyperplasia of mammary glands (2) Familial aggregation of breast cancer (the definition of familial clustering tendency of breast cancer and recommendations for high-risk individuals with a high incidence of breast cancer in their family); (3) marriage, childbirth, and breast cancer (how marriage, childbirth, and contraceptives affect the incidence of breast cancer by affecting estrogen). AE (Adobe after Effects) and AI (Adobe Premiere) were used to clip the video and design the background, mask, and text layers to form the progress bar. The pink mask gradually expands over time to cover the background layer, allowing viewers to visually see the progress of the video. The work was completed under the direction of a Ph.D. in sociology and a breast surgeon, who acted as gatekeepers for the video design and scientific rationality, respectively. The duration of the video was between 3 and 4 min. Except for the variables we studied, all control variables in every pair of videos were completely consistent (
