Purpose. We investigated the effectiveness of narrative versus non-narrative messages in changing COVID-19-related perceptions and intentions.
Design/Setting. The study employed a between-subjects two-group (narratives versus non-narratives) experimental design and was administered online.
Subjects/Intervention. 1,804 U.S. adults recruited via Amazon MTurk in September 2020 were randomly assigned to one of two experimental conditions and read either three narrative or three non-narrative messages about social distancing, vaccination, and unproven treatments.
Measures. Perceptions and intentions were assessed before and after message exposure (7-point scales).
Analysis. Using multivariable regression, we assessed main effects of the experimental condition (controlling for baseline measures) and interactions between the condition and pre-exposure perceptions/intentions in predicting post-exposure outcomes.
Results. Compared to non-narratives, narratives led to 1) less positive perceptions about the benefits of unproven treatments (Mnarrative=3.60, Mnon-narrative =3.77, p=.007); and 2) less willingness to receive an unproven drug (Mnarrative=3.46, Mnon-narrative=3.77, p<.001); this effect was stronger among individuals with higher baseline willingness to receive unproven drugs (baseline willingness=2.09: b=-0.06, p=.461; baseline willingness=3.90: b=-0.30, p<.001; baseline willingness=5.71: b=-0.55, p<.001). Narratives also led to more positive perceptions of vaccine safety/effectiveness, but only among individuals with lower baseline vaccine perceptions (baseline perceptions=4.51: b=0.10, p=.008; baseline perceptions=5.89: b=0.04, p=.167; baseline perceptions=7: b=-0.01, p=.688).
Conclusion. Narratives are a promising communication strategy, particularly for topics where views are not entrenched and among individuals who are more resistant to recommendations.
