Prosocial youth less likely to associate with deviant peers, engage in problem behaviors

Intervention programs should focus on encouraging youth to volunteer, help others

2014-03-11
(Press-News.org) COLUMBIA, Mo. – Prosocial behaviors, or actions intended to help others, remain an important area of focus for researchers interested in factors that reduce violence and other behavioral problems in youth. However, little is known regarding the connection between prosocial and antisocial behaviors. A new study by a University of Missouri human development expert found that prosocial behaviors can prevent youth from associating with deviant peers, thereby making the youth less likely to exhibit antisocial or problem behaviors, such as aggression and delinquency.

"This study reaffirms suspicions that youth who engage in some forms of prosocial behaviors, such as helping, volunteering and comforting others, are less likely to engage in antisocial behaviors such as aggression and affiliating with deviant peers," said Gustavo Carlo, the Millsap Professor of Diversity in the MU Department of Human Development and Family Studies.

Carlo and his colleagues surveyed more than 650 adolescent children in Valencia, Spain, about their prosocial behaviors, affiliations with deviant peers, and delinquent and aggressive tendencies.

Of the six forms of prosocial behaviors measured, Carlo found that only two forms, altruism and compliancy, significantly reduced the chances of adolescents' displaying problem behaviors. Compliant prosocial behaviors are actions that often require some level of social conformity and respect for authority, while altruistic behaviors are actions done without concern for self-reward.

Carlo said identifying which forms of prosocial behaviors are related to antisocial behaviors has important implications for intervention programs designed to reduce problem behaviors and promote more constructive prosocial behaviors in adolescents.

"Developers of intervention programs could use these findings to create programs that teach youth the benefits of engaging in prosocial behaviors," Carlo said. "Such preventative efforts may be most effective in preventing youth from affiliating with deviant peers and from engaging in subsequent aggressive and delinquent behaviors."

The Department of Human Development and Family Studies is part of the MU College of Human Environmental Sciences. The study, "The protective role of prosocial behaviors on antisocial behaviors: the mediating effects of deviant peer affiliation," will be published in the Journal of Adolescence. Carlo's co-authors included researchers from the Chicago School for Professional Psychology, the University of Nebraska-Lincoln and the University of Valencia in Spain.

Finding hiding place of virus could lead to new treatments

2014-03-11
WINSTON-SALEM, N.C. – March 11, 2014 – Discovering where a common virus hides in the body has been a long-term quest for scientists. Up to 80 percent of adults harbor the human cytomegalovirus (HCMV), which can cause severe illness and death in people with weakened immune systems. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report that stem cells that encircle blood vessels can be a hiding place, suggesting a potential treatment target. In the American Journal of Transplantation (online ahead of print), senior scientist ...

First human totally endoscopic aortic valve replacements reported

First human totally endoscopic aortic valve replacements reported
2014-03-11
Beverly, MA, March 11, 2014 – Surgeons in France have successfully replaced the aortic valve in two patients without opening the chest during surgery. The procedure, using totally endoscopic aortic valve replacement (TEAVR), shows potential for improving quality of life of heart patients by offering significantly reduced chest trauma. It is described in the Journal of Thoracic and Cardiovascular Surgery, an official publication of the American Association for Thoracic Surgery. Endoscopic surgery is already used by cardiovascular surgeons for procedures such as atrial ...

Global survey of urban birds and plants find more diversity than expected
2014-03-11
AMHERST, Mass. – The largest analysis to date of the effect of urbanization on bird and plant species diversity worldwide confirms that while human influences such as land cover are more important drivers of species diversity in cities than geography or climate, many cities retain high numbers of native species and are far from barren environments. Urban ecologist Paige Warren of the University of Massachusetts Amherst, co-leader of a 24-member research working group at the University of California Santa Barbara's National Center for Ecological Analysis and Synthesis ...

Diets high in animal protein may help prevent functional decline in elderly individuals

2014-03-11
A diet high in protein, particularly animal protein, may help elderly individuals function at higher levels physically, psychologically, and socially, according to a study published in the Journal of the American Geriatrics Society. Due to increasing life expectancies in many countries, increasing numbers of elderly people are living with functional decline, such as declines in cognitive ability and activities of daily living. Functional decline can have profound effects on health and the economy. Research suggests that aging may reduce the body's ability to absorb or ...

Substance naturally found in humans is effective in fighting brain damage from stroke

2014-03-11
DETROIT – A molecular substance that occurs naturally in humans and rats was found to "substantially reduce" brain damage after an acute stroke and contribute to a better recovery, according to a newly released animal study by researchers at Henry Ford Hospital. The study, published online before print in Stroke, the journal of the American Heart Association, was the first ever to show that the peptide AcSDKP provides neurological protection when administered one to four hours after the onset of an ischemic stroke. This type of a stroke occurs when an artery to the brain ...

NASA's Aqua and TRMM satellites have been providing rainfall data, cloud heights and temperature and other valuable information to forecasters at the Joint Typhoon Warning Center as they track Tropical Cyclones Hadi and Lusi in the South Pacific. NASA's Aqua satellite captured both storms in one infrared image on March 10 at 14:47 UTC/10:47 a.m. EST. At that time, Hadi was near the east Queensland coast while Lusi was several hundred miles north of New Caledonia. The Atmospheric Infrared Sounder or AIRS instrument captured infrared data that was used to create a false-colored ...

Scientists from Penn and CHOP confirm link between missing DNA and birth defects

2014-03-11
In 2010, scientists in Italy reported that a woman and her daughter showed a puzzling array of disabilities, including epilepsy and cleft palate. The mother had previously lost a 15-day-old son to respiratory failure, and the research team noted that the mother and daughter were missing a large chunk of DNA on their X chromosome. But the researchers were unable to definitively show that the problems were tied to that genetic deletion. Now a team from the University of Pennsylvania and The Children's Hospital of Philadelphia has confirmed that those patients' ailments ...

Lessons learned managing geriatric patients offer framework for improved care

2014-03-11
A large team of experts led by a Johns Hopkins geriatrician reports that efforts to improve the care of older adults and others with complex medical needs will fall short unless public policymakers focus not only on preventing hospital readmission rates, but also on better coordination of community-based "care transitions." Lessons learned from managing such transitions for older patients, they say, may offer a framework for overall improvement. Nationwide, some 22 percent of older adults experience so-called care transitions annually, moving from and among hospitals, ...
