In algorithmically curated environments where science videos reach audiences primarily through incidental exposure rather than active seeking, understanding viewers’ perceived effects provides insights for communicating science effectively. We developed and validated a multidimensional scale measuring perceived effects of watching science videos through three sequential studies. Study 1 used an open-ended survey to generate items ( N = 150), Study 2 employed a close-ended survey for factor identification ( N = 309), and Study 3 tested criterion validity ( N = 286). We identified five dimensions of perceived effects: information acquisition, practical application, enjoyment, time-passing, and social interaction. These dimensions show varied associations with content exposure and perceptions of science.
