Vaccinating for My Family or for My Community? The Effect of Message Framing on Parental Intention to Vaccinate during the COVID Pandemic.
Trial report in International journal of behavioral medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSocial media is one of the major platforms for disseminating essential health messages. The present study examined the effect of message framing (self-interest motive, prosocial motive) on an online platform for parental intention to vaccinate against COVID-19. It also examined how the effect may vary across participants' levels of parental identity centrality/salience and community orientation before the vaccine was officially available.
methodsSix hundred and sixty-three Hong Kong Chinese parents were recruited, and a total of 278 valid responses were retained in the analyses. Participants were randomly assigned to one of the three conditions: self-interest motive, prosocial motive, and control. Participants in the self-interest motive condition and the prosocial motive condition read a condition-specific message about the COVID-19 vaccine. Then, they reported their levels of intention to vaccinate against COVID-19, including parent-vaccination, child-vaccination, and medical information-seeking.
resultsA significant group effect on child-vaccination was found. Participants in the self-interest motive condition reported a higher intention to vaccinate their children against COVID-19 compared with the other two conditions. Results of moderation analyses indicated that communal orientation moderated the effect of a self-interest-motive-emphasized message on parental intention to vaccinate against COVID-19. The effect of a self-interest-motive-emphasized message appeared to be stronger on parent-vaccination, child-vaccination, and medical information-seeking among parents who reported lower levels of communal orientation.
conclusionThese findings provided some initial evidence of the effectiveness of message-framing in promoting parents' intention to vaccinate their children on online platforms.
