Summary

This study is a PhD project conducted by Ms. Hina Hakim, supervised by Dr. Holly O. Witteman, PhD, and co-supervised Dr. Daniel Reinharz, professors and researchers at the Faculty of Medicine at Laval University. The purpose of this study is to evaluate the effects of visualization conveying the concept of community immunity or herd immunity on risk perception (towards individual, family, community and vulnerable people in communities) (primary outcome) and on emotions, attitudes, knowledge, and behavioural intentions (secondary outcomes).

Conditions

  • Vaccine-Preventable Diseases

Interventions

BEHAVIORAL

herdimm

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.
