ANN ARBOR — Researchers at the University of Michigan Life Sciences Institute found that a previously dismissed genetic mechanism may contribute to nicotine dependence, and to the withdrawal effects that can make quitting smoking so difficult. (more…)
ANN ARBOR — It’s a sad but familiar scene near the grounds of many medical campuses: hospital-gowned patients, some toting rolling IV poles, huddled in clumps under bus shelters or warming areas, smoking cigarettes.
Smoking causes 30 percent of all cancer deaths and 87 percent of all lung cancer deaths. Yet, roughly 50 percent to 83 percent of cancer patients keep smoking after a cancer diagnosis, through treatment and beyond, says Sonia Duffy, University of Michigan School of Nursing researcher. For patients who quit on their own, relapse rates (as in the general population) are as high as 85 percent. (more…)
*MU researchers say disgusting and threatening ads can cause strong defense responses from viewers*
COLUMBIA, Mo. – Health communicators have long searched for the most effective ways to convince smokers to quit. Now, University of Missouri researchers have found that using a combination of disturbing images and threatening messages to prevent smoking is not effective and could potentially cause an unexpected reaction.
In a study recently published in the Journal of Media Psychology, Glenn Leshner, Paul Bolls and Kevin Wise, co-directors of the Psychological Research on Information and Media Effects (PRIME) Lab at the University of Missouri School of Journalism, found that showing viewers a combination of threatening and disgusting television public service announcements (PSAs) caused viewers to experience the beginnings of strong defensive reactions. The researchers found that when viewers saw the PSAs with both threatening and disgusting material, they tended to withdraw mental resources from processing the messages while simultaneously reducing the intensity of their emotional responses. Leshner says that these types of images could possibly have a “boomerang effect,” meaning the defensive reactions could be so strong that they cause viewers to stop processing the messages in the PSAs.

ANN ARBOR, Mich.— Brain scans showing neural reactions to pro-health messages can predict if you’ll keep that resolution to quit smoking more accurately than you yourself can. That’s according to a new study forthcoming in Health Psychology, a peer-reviewed journal.
“We targeted smokers who were already taking action to quit,” said Emily Falk, the lead author of the study and director of the Communication Neuroscience Laboratory at the U-M Institute for Social Research and Department of Communication Studies. “And we found that neural activity can predict behavior change, above and beyond people’s own assessment of how likely they are to succeed.
