REGRESSION
To quantify the participants’ engagement, we will use the graphical experiment builder in Gorilla to give participants an option to rewatch the video before ending the study. We will record a timestamp when the participant reaches the end of the second time point, the moment when they play the videos, and the moment when they end the study. Participants who skip the video or watch it for less than 3 seconds are considered as not engaging. For the participants who watch the video, we will record the length of time spent watching the videos. We will use regression models to describe the effects of sociodemographic factors and the Sodium questionnaire score with engagement time.
