Conclusions
The authors conclude that negative experiences are more influential on depression symptoms than positive experiences, which might be to do with the tendency for people to focus more on the negative aspects of self, others and the world around us (called negativity bias).
The authors also highlight the complexity operating in terms of the types of social relationships that exist within the context of social media. They propose that people connected via social media may not have close and trusting relationships but be more like casual acquaintances and that this kind of distant relationship may increase feelings of disconnection as well as misunderstandings, resulting in negative experienes and increased depression.
