The relationships between social media use and factors relating to depression.

Social media is profoundly changing the way many people interact, and there are growing concerns that social media use is negatively affecting individual’s mental health. This chapter will review research which has correlated social media use to measures relating to depression, self-esteem, anxiety and loneliness. Additionally, we review the reported benefits of using social media relating to mental health, such as enhanced self-expression, online support and enhanced socialising capabilities. We then evaluate theories and models that have been proposed to explain the relationships between social media use and depression. In the final section, we highlight some methodological limitations with prior research and suggest future directions.
