Researchers Tackling Misperceptions About Ecigs

Posted 3rd June 2021 by Dave Cross
Researchers have looked at how effective expert videos are at tackling smoker misperceptions about electronic cigarettes and vaping. Madeleine Svenson, James Green, and Olivia Maynard found that carefully designed public health information videos are good at combatting the “pervasive misperception”.

The study published in the latest edition of Nicotine & Tobacco Research (1) comes from the researchers who work at University of Bath’s Department of Psychology and School of Psychological Science and the University of Bristol’s Integrative Epidemiology Unit.

The trio say that vaping represents an opportunity to stop tobacco use for many smokers. They agree that ecigs pose less than 5% of the harm of tobacco products. They state that evidence demonstrates that vaping is both an effective smoking cessation technique and a significantly reduced harm alternative to smoking.

Despite this,” they write, “e-cigarettes are still met with widespread uncertainty by smokers. A Public Health England report estimates that 40% of smokers have never tried an e-cigarette, often due to misperceptions surrounding their safety. Over time, these misperceptions appear to be becoming more prominent. Between 2014 and 2019, the proportion of English smokers who correctly believed e-cigarettes were less harmful than cigarettes reduced from 45% to 34%. This pattern is mirrored in the US and inaccurate harm perceptions are most common among smokers who do not vape. There is therefore an important public health need to challenge these widespread misperceptions.”

They note that many public health information campaigns fail because even when they debunk myths and lies, “misinformation still influences decisions after corrections are acknowledged, and more concerningly, corrective information often backfires, accidently reinforcing the misperceptions it is designed to challenge”.

They conducted an online between-subjects experimental study in February 2020 with UK smokers who do not use e-cigarettes. The participants were randomised into one of three groups: watching a video by Cancer Research UK (CRUK), a video featuring proclaimed experts, and one receiving no messaging. In total, 390 subjects took part in the study.

They found, “that exposure to a short CRUK infographic video, and especially a video featuring e- cigarette experts, meaningfully corrected e-cigarette misperceptions among adult smokers who do not vape and increased their intentions to try an e-cigarette, compared to control participants who saw no video. Supporting previous findings, we observed high levels of misperceptions among those in our control group who saw no video, with these participants providing stronger endorsement for misbeliefs such as second-hand e-cigarette vapour can expose others to harm ‘and e-cigarettes often contain chemicals that are harmful to users health. Given the potential of e-cigarettes to reduce harm among current smokers, our findings indicate the significant public health potential of these brief video interventions.”
