Abstract: This paper examined the effects of message modality (video/text) and type of sources (official/unofficial) on perceived credibility of misinformation on social media, health attitudes and behaviors. The results of a 2x2 randomized experiment (N=190) showed significant effects of video modality on perceived credibility of misinformation about the Ebola virus, as well as perceived vaccine danger. Moderating effects of trust in institutions and political ideology were also investigated. The results are interpreted in light of information processing theories.
