Background: In health education, there is a risk of giving overly prescriptive recommendations, potentially activating conflicting in-group norms that reduce message receptiveness. For example, the notion of 'unhealthy youth' is a stereotype which suggests that young people are expected to make unhealthy choices. If such in-group norms are…

Using a population-based sample of 1,311 seventh graders in an urban school district in the South Central United States, we examined the associations between early-life trauma, anger regulation, and early adolescent perceptions about sex and parenthood. Girls and boys with more trauma exposure were more likely to perceive adolescent parenthood as…

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 (M = 11.21 years) to Grade 10 (M = 16.25 years) provided self-reports of delinquency. Friendships were identified from…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

Through the influences of our social environment, both boys and girls learn their sexual norms, specific rules and values from the early childhood. Hence, children grow up in the world of distinct sexual duality. In their efforts to act according to their sexual stereotypes, children adopt these widespread stereotyped conceptions in developing…

The objectives of this paper are twofold. First, a research model, namely, Model for the Study of Bullying and Other School Violence, is proposed, outlined, and delineated, arguing that this model is theoretically grounded and empirically validated by reviewing the related literature. In this model, five major components are proposed that are…

In most ways the island nations of Iceland and Singapore could not be more different from each other: Iceland is sparsely populated, located near the Arctic Circle, and a very free and individualistic democratic society; Singapore is densely populated, located near the equator, and a very regulated and collectivist meritocracy. But both nations…

The nation's youth are increasingly affected by violence, both as its perpetrators and as its victims. Many violence prevention programs aim to reverse this trend, but few have been rigorously evaluated, and even fewer have been shown to work. To devise better programs, researchers need more information. To that end, RAND researchers identified…
