Effects of Anti- vs. Pro-vaccine Narratives on Responses by Recipients Varying in Numeracy: A Cross-sectional Survey-Based Experiment

摘要

PurposeTo inform their health decisions, patients may seek narratives describing other patients' evaluations of their treatment experiences. Narratives can provide anti-treatment or pro-treatment evaluative meaning that especially low-numerate patients struggle to derive from statistical information. Here, we examined whether anti-vaccine (vs. pro-vaccine) narratives had relatively stronger effects on the perceived informativeness and judged vaccination probabilities reported among recipients with lower (vs. higher) numeracy.
