According to the latest research presented in a special issue of Developmental Psychology, published by the American Psychological Association (APA), spending a lot of time on the Web can have both negative and positive effects on young people, i.e., the sharing of self-injury practices by some and the improvement of academic performance and health awareness by others.

"A major goal for this cumulation of research is to show the good and bad sides of the Internet as it relates to children," said coeditors of the special issue Patricia Greenfield, PhD, of the Children's Digital Media Center, University of California at Los Angeles and Zheng Yan, PhD, of the State University of New York at Albany.

In a series of six articles, leading researchers examine normal behavior in chat rooms and the use of message boards by adolescents who self-injure, uses of the Internet to improve academic achievement among low-income youth and ways to provide health information to youth living in developing countries. Researcher Yan examines the importance of age in understanding the social and technical aspects of the Internet; Subrahmanyam and colleagues look at why adolescents reveal their identities and sexuality online differently when in monitored versus nonmonitored virtual environments; while Cassell and colleagues investigate how language use and linguistic styles of adolescents in an online community can predict leaders.

To understand the role the Internet plays in linking marginalized adolescents and spreading potentially damaging behaviors, Cornell University researchers Janis L. Whitlock, PhD, Jane L. Powers, PhD, and John Eckenrode, PhD, explored the role Internet message boards play in creating communities centered around self-injurious practices. Self-injurious behavior typically refers to a variety of behaviors in which the individual purposefully inflicts harm to his or her body without the obvious intent of committing suicide. The authors observed 406 message boards to investigate how adolescents solicit and share information related to self-injurious behavior. Females 14-20 years of age visited these bulletin boards the most.

The findings show that online interactions provide essential social support for otherwise isolated adolescents, but these online boards may also normalize and encourage self-injurious behavior and add potentially lethal behaviors to the repertoire of established adolescent self-injurers and those exploring identity options, said lead author Whitlock.

The authors also found that Internet message boards provide a powerful vehicle for bringing together self-injurious adolescents. Although the message boards examined for these two studies may not be representative of all self-injury message boards, they do provide a snapshot of content and exchange common in those with high activity. In the last five years, "hundreds of message boards specifically designed to provide a safe forum for self-injurious individuals have come into existence and may expose vulnerable adolescents to a subculture that normalizes and encourages self-injurious behavior," said Whitlock.

The Internet can also be a good educational tool for hard-to-reach populations. Researchers from Michigan State University examined the positive effects of home Internet access on the academic performance of low-income, mostly African American children and teenagers in their article, "Does Home Internet Use Influence the Academic Performance of Low-Income Children? Findings from the HomeNetToo Project." In this research, 140 children aged 10-18 years old (83% African American and 58% male) living in single-parent households (75%) with a $15,000 or less median income were followed for a two-year period to see whether home Internet use would influence academic achievement.
