An Evaluation of a Dynamic Web-Based Visualization of Community Immunity
Visão geral do estudo
Status
Descrição detalhada
Visualization is a powerful communication mechanism that uses pre-attentive processing to communicate large amounts of information rapidly in understandable and compelling ways (Healey and Enns 2012). A systematic review demonstrates that there are some interventions available for conveying the concept of community immunity, and very few evaluate interventions for their effects on vaccine intentions and uptake as well as their precursors, such as knowledge, attitudes, knowledge and none on emotions (Hakim et al. 2018).
The purpose of this study is to evaluate the effects of visualization conveying the concept of community immunity on risk perception (to individual, family, community and vulnerable people in communities) (primary outcome) and on emotions, attitudes, knowledge, and behavioural intentions (secondary outcomes).

In this visualization participants can build their own avatar representing themselves and 8 other avatars representing people around them, like their family or coworkers.
Our visualization then uses these avatars in a brief narrated video explaining how herd immunity works.
