Beyond Informing and Entertaining: Developing and Validating a Scale for Perceived Effects of Watching Science Videos on Social Media

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.
