Questions 64-67 are based on the following passage.

    In 2012, anxiety UK conducted survey on social media use and its effects on emotions. The survey found that 53% of participants said social media sites had changed their behavior.

    Those who said their lives had been worsened by using social media also reported feeling less confident when they compared their achievements against their friends. Furthermore, the survey revealed that two thirds of participants reported difficulty relaxing and sleeping after they used the sites, while 55% said they felt "worried or uncomfortable" when they were unable to log onto their social media accounts. In a more recent study, social interaction on social media sites, specifically Facebook, may have a negative impact on face-to-face encounters for individuals who already have high levels on anxiety.

    Another concern regarding social media use is cyber bullying. As stated earlier in this feature, the majority of social networking users are under the age of 30, and most of these are adolescents. According to Enough is Enough (EIE) an organization that aims to make Internet use safer for children and families - 95% of teenagers 269 who use social media have witnessed forms of cyber bullying on social networking sites. In addition, 33% have been victims of cyber bullying. But Dr. Rauch believes it is not purely the use of social media that is getting out of control. It is more on our need to be electronically connected at all time. Dr. Rauch further says, "I would encourage any parent to explore ways to encourage or even mandate 'off' time, not just away from social media sites, but away from the devices. That is probably good advice for all of us."

    Although many studies point to the negative impacts of social media on mental health and well-being, some researchers say they could have to opposite effect. Social networking sites could be a useful tool in identifying individuals with mental health issues.

    Some studies have suggested that social media use may even improve mental health and well-being. Last year, Medical News Today reported that Facebook activity may be an indicator of a person's psychological health. It was found that people who shared fewer pictures on the site, communicated less frequently, had a longer profile and fewer Facebook friends were more likely to experience social anhedonia. This is the inability to encounter happiness from activities that are normally enjoyable, such as talking to friends. However, another study suggests that using social media may even spread happiness.

    Overall, it appears that the exact effects of social media on our mental health and well-being remain to be seen. But one thing is certain; our use of social networking sites us unlikely to fade a nytime soon.
