Prior exposure to conflicting health files reduces receptivity to urged health conduct messages, peek says

University of Minnesota researchers are finding that prior exposure to conflicting health files reduces receptivity to messages about widely-urged health behaviors.

At the present time’s public files surroundings is characterized by conflicting files about a huge differ of health matters, in conjunction with nutrition, most cancers screening, e-cigarettes, and most now not too lengthy ago, COVID-19. Research has shown exposure to conflicting files can negatively beget an impact on public belief and trust in health suggestions.

What is now not recognized is whether or now not or now not such exposure could perhaps contain folks much less receptive to other health messages, in conjunction with those about widely urged health behaviors for which there is miniature war, similar to fruit and vegetable consumption and physical exercise. The likelihood of such “carryover effects” from exposure to conflicting files used to be now not too lengthy ago examined by an interdisciplinary crew of University of Minnesota researchers.

Published within the journal Annals of Behavioral Medication, the U of M peek eager a 3-wave, online watch experiment with a representative sample of in the case of 3,000 U.S. adults all around the summer of 2020. Participants had been randomly assigned to leer a sequence of health news experiences and social media posts about six various health matters in conjunction with mammography screening and carbohydrate consumption. These experiences and posts, which had been shown to participants twice over a month-lengthy period, differed most attention-grabbing in whether or now not they featured war over scientific evidence or guidance. No longer now not as a lot as one week after their 2d viewing, participants had been requested to evaluate advertisements from a complete lot of most recent health campaigns about behaviors for which there is nice scientific consensus: Fruit and vegetable consumption, physical exercise, and colorectal most cancers screening.

Outcomes confirmed that prior exposure to conflicting health files rendered folks much less receptive to messages about these widely urged health behaviors.

These that had been previously exposed to war reported higher resistance to the health campaign advertisements, as properly as decrease perceptions of the health behaviors featured in those advertisements.

Statistical diagnosis indicated that carryover effects largely operated through folks’s feelings of backlash in direction of health suggestions and learn in current, which used to be elicited by their prior exposure to war.

“These outcomes are worrisome, seriously given a COVID-19 files panorama that’s increasingly more fraught with seemingly conflicting science, as our crew’s previous learn has shown,” stated Rebekah Nagler, peek lead and an accomplice professor within the Hubbard Faculty of Journalism and Mass Communication, and a Masonic Cancer Heart member. “Indirectly, folks’s cumulative, routine exposure to conflicting files about COVID-19 and other health concerns could perhaps threaten the success of media campaigns and other public health messaging suggestions—suggestions that we as a nation make investments in heavily yr after yr to discontinue most cancers and other power ailments.”

Nagler and her colleagues are now focused on intervene and interrupt the carryover phenomenon and better keep in touch with the public about evolving science.
