Methods
We used a Critically Appraised Topic approach (Brennan et al., 2020;
White, Raghavendra, & McAllister, 2017) to identify descriptions and
evaluations of evidence-based communication interventions to increase
HeVD vaccine uptake for horses by horse
owners.
The term “communication intervention” is defined as any medium used to
deliver information and ideas between parties to aid discussion of
topics of common interest, as well as inform, guide, and motivate a new
or existing behaviour (IGI Global, n.d.; Robyn & Charlotte, 2010; World
Organisation for Animal Health, 2018). Communication interventions
include face-to-face conversation, telephone conversation,
videoconferencing, articles, pamphlets, email, blog posts, social media
posts, website pages, smartphone apps, radio, and television (University
of Minnesota, 2017). The term ‘evidence-based’ in this context refers to
interventions that have been developed following research to
systematically promote HeVD vaccination uptake.
Searches were conducted in July 2022 using the terms “Hendra*” and
“Vaccin*” and “Communicat*” or “Behavio* change” and “Horse
owner*” and “Australia*”, in BIOSIS Previews Via Web of Science,
Scopus, and Medline via Ovid (Supplementary Information, Table S1).
Duplicates were removed, then records were screened on title and
abstract and retained if they were relevant to the research question,
peer-reviewed, and in English. Data were extracted from these records
relevant to communication interventions, and the domains of behavioural
and social drivers of vaccine uptake in the BeSD framework (WHO, 2022a).
