Internet use involves both pros and cons for children and adolescents
Some youth benefit from Internet use while for others it can exacerbate self-destructive behaviorsWASHINGTON -- Between 75 and 90 percent of teenagers in the United States use the Internet to email, instant message (IM), visit chat rooms and explore other sites on the World Wide Web. 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.
The children who participated in the HomeNetToo project were online for an average of 30 minutes a day. Findings indicate that children who used the Internet more had higher standardized test scores in reading and higher grade point averages (GPAs) at one year and at 16 months after the project began compared to children who used the Internet less, said lead author Linda Jackson, PhD. Internet use had no effect on standardized test scores in math.
"Improvements in reading achievement may be attributable to the fact that spending more time online typically means spending more time reading," said Dr. Jackson. "GPAs may improve because GPAs are heavily dependent on reading skills," she added.
In another article showing the positive effects of Internet use, researchers from Johns Hopkins University and the University of Ghana looked at the benefits of teens using the Internet for health information in the developing world, where access to health information is scarce. The study surveyed 778 15- to 18-year-olds living in Accra, Ghana, who were either in school or out of school on their Internet usage and knowledge of health information. Two thirds (66%) of the youth who were in school and around half (54%) of the youth who were out of school had gone online previously.
The authors found that regardless of these users' school status, gender, age or ethnicity, 53% went online to find health information. In fact, the Internet was even a relatively more important source for out-of-school than for in-school youth, a finding with important social implications. Youths said the Internet provided interesting material that helped them solve a problem or answer a question. The most common topics searched on the Internet for in-school youth were sexually transmitted diseases, diet/nutrition and fitness and exercise. For the out-of-school youth, sexually transmitted diseases, sexual activities and sexual abuse were the topics of choice.
"Out-of-school youth in Ghana may have parents with less formal education than the in-school youth, and this may inhibit certain discussions around sex and health," said lead author Dina L. G. Borzekowski, EdD. "With HIV/AIDs rampant in Africa, our finding has tremendous public health implications. The Internet may be an increasingly effective way to reach lower socioeconomic youth with prevention messages." Furthermore, the Internet is invaluable for adolescents who want to find out more about personal, sensitive and embarrassing issues related to their bodies, relationships and health, she added.
