Questionário PLOT-TWIST : um instrumento preliminar para analisar a popularidade do comunicador de assuntos de saúde em vídeos de YouTube

Abstract

Videos from credible sources on the YouTube platform, as produced by universities/health organizations, are relatively scarce. The number of institutional videos that become highly popular on these platforms is even lower. The ability to disseminate a useful source of information is a skill to be developed by scientists and dissemination specialists, but it seems to be directly dependent on an affective component. There are still no instruments to measure the popularity of viral or popular videos on YouTube that assess the verbal and non-verbal communication skills of communicators in the field of health. For this, we developed the PLOT-TWIST questionnaire to further investigate the qualities related to the communicator that would provide greater and stronger connections with the public. With that, objective and subjective credibility values described in the literature as important for the popularization of content were gathered in a construct, which was subsequently evaluated by three specialists. Agreement between experts was low regarding the measure. The subjective domain, more directed to the affective component, presented a content validity index below satisfactory. The objective domain related to content and platform, which contained classic popularization metrics such as likes and shares, showed a high content validity index despite the low interrater agreement. The objective domain related to content and platform The content validity study of the PLOT-TWIST instrument provided guidance for the review of the measure, but still did not allow determining which and how the elements should be revised. Expanding the panel of experts and introducing other evaluation parameters could contribute to a more consistent review of the instrument allowing further pre-test application on a sample of popular YouTube health videos.
