Interactive websites more engaging for some people could actually discourage other users from adopting healthy behaviors, said researchers.

‘Smokers who had limited familiarity with information technology were more likely to consider antismoking messages manipulative and boring when they browsed those messages on a website with interactive features, such as sliders, mouseovers and zooming tools.’

According to Sundar, adding interactive features to websites tends to be a popular way to increase user engagement. However, in the past researchers have cautioned health communicators about the potential of boomerang effect, in which interactivity may make certain people more defensive. 




"In this case, the more that smokers interacted with the site, the more defensive they became, and this negatively affected their engagement with its content," said Sundar, who worked with Jeeyun Oh, assistant professor of advertising, University of Texas at Austin.
For nonsmokers and people who were comfortable with technology -- also called power users -- the interactive features had the opposite effect. As they clicked and dragged sliders repeatedly, they felt more focused and absorbed, and said the anti-smoking message was more accurate and believable.
"Not only users' attitudes toward the messages, but also their beliefs regarding the negative consequences of smoking can be swayed by getting them more engaged while browsing the site," said Oh, the lead author of the study. "It is very intriguing to see that user engagement with interactive features can influence their beliefs about whether smoking can cause serious health issues or not, even after we controlled for their baseline beliefs in the analysis. Those who reported being more engaged also showed greater smoking outcome beliefs."
The researchers, who released their findings in the journal Health Communication, suggest that health communicators may want to develop different websites based on how targeted audiences may react to interactive features. For example, a website aimed at preventing nonsmokers from starting may offer more interactive features, while one that aims to help smokers quit may use less of those tools.

"Perceptual bandwidth is the degree to which our different sensory channels are involved in processing a message," said Sundar. "If you think of perceptions as a pipe ... we can only see so much in a TV story, or we can only get so much by listening to a radio report. But interactive tools enhance the amount of information that we perceive. When we provide the ability to interact, online users can explore and can process more information that is embedded in the stimuli."

"In this study, we measured their on-screen user action from behind the scenes," said Sundar. "We actually tapped into what was going on under the hood, in terms of their actions, like clicking and dragging, and were surprised to discover that it was related to their attitudes toward smoking, not just the site."
