Design outcomes

Primary

MeasureTime frame
It is estimated that the neural network model to be developed based on the proposed intervention will classify a video of a particular person reading content related to the use of fluorides and inform whether the content is fake or not. To this end, the psychophysiological reactions of individuals during the consumption of content, such as facial actions and heart rate, will be evaluated.

Secondary

MeasureTime frame
It is expected that individuals with higher levels of e-health literacy and knowledge about oral health, younger, with a higher educational level, and who frequently health information-seeking behavior, have different psychophysiological reactions compared to their peers. Therefore, these outcomes will be determined by applying three specific questionnaires. Finally, it is estimated that participants in the test group feel more stressed during the experiment. Thus, the emotional state of all individuals will also be evaluated through a specific questionnaire, determining their levels of arousal (calm or agitated) and valence (positive or negative feeling towards the contents).
