Social anxiety is fear of social situations, including interactions with unfamiliar people, and of being judged negatively by others. Social anxiety is one of the most common mental disorders among children and teens, affecting five percent of them. An attributing factor to social anxiety is social media, an important part of adolescents’ lives as it provides another mode of social interactions. However, it can often be used excessively. With social media becoming more popular as the use of online communication increases, there has been a link between social media use and its effect on adolescents' social anxiety. While social media has been seen to be beneficial among teens, such as the ability to stay in touch with friends, there have also been negative effects. Although it is no longer the most popular among teenagers, Facebook has been at the forefront of research on social anxiety. Comparisons between different ages and genders have not been explored. Also, apps that tend to be more popular among teenagers such as Instagram, Snapchat, and Tiktok have not been researched as much as Facebook. In order to fill these gaps in literature I plan to send out a questionnaire called the Translated Version of the Social Anxiety Scale for Social Media Users (SAS-SMU) to students in order to identify differences in effects between genders and ages. I hypothesize that social media will affect females more than males, and older high schoolers around students who are 17 and 18 years old will experience more effects from social media. This research is important because social media is very relevant in teens' lives and about 90% of teens (ages 13-17) have some form of social media and spend about nine hours on their phone daily. If significant results are shown where social media greatly affects social anxiety then there can be further research done to see how teens can limit their use or how various social media apps can alter how teens use the app.
