Recent years have brought a significant increase in the popularity of social media sites. These sites have become so widely used by younger generations that it affects them both physically and psychologically. The most popular social media sites, especially Facebook and Twitter, allow users to post their own comments, regardless of their content. While at first glance this seems perfectly correct, the consequences of mostly unmonitored messages have been shown to have a direct relationship with increased violence, particularly bullying, racism and psychological problems especially in vulnerable adolescents. Clarke-Pearson, Kathleen and Gwenn S. O'Keeffe. “The Impact of Social Media on Children, Adolescents, and Families.” The impact of social media on children, adolescents and families. American Academy of Pediatrics and its Board of Directors, March 28, 2011. Web. November 5, 2013. Both Kathleen Clarke-Pearson, MD, and Gwenn Schurgin O'Keeffe, MD, are leading child health experts and experts on cybersecurity, while Kathleen Clarke-Pearson, MD, is chair of the North Carolina Pediatric Society of Medicine Committee. This source is mainly written to show parents how their children are influenced by social media. Clarke-Pearson and O'Keefe say that children and adolescents are very sensitive to peer pressure which immediately puts them in danger because they are exposed to the opinions of so many people on a daily basis through social media. They continue to say that the most common forms of risk are cyberbullying, sexting and Facebook depression. These risks lead to “profound psychosocial outcomes including depression, anxiety, severe isolation, and, tragically, suicide (Clarke-Pearson and O'Keefe).” This source is valuable because the information in it is written in a very informative way and is the result of extensive research. I would like to use the many statistics on social media use in families to provide a solid argument in my article that can relate to families who may be misinformed.
