One study by Primack et al. found that the number of social media platforms used was a strong indicator of anxiety and depression (2017). Their results state that the “Use of multiple SM platforms is independently associated with symptoms of depression and anxiety, even when controlling for overall TSSM (time spent on social media)” (2017). More specifically, those who use 7-11 platforms have “substantially higher odds” of having depression and anxiety symptoms compared to those participants who use 0-2 platforms (2017).
Another study by Lin et al., examined total time spent on social media and found that “Compared to those in the lowest quartile of total time per day spent on SM, participants in the highest quartile had significantly increased odds of depression” (2016). It is unclear how many of those in the highest quartile were predisposed to anxiety and depression and whether those symptoms would have been displayed otherwise.
Speaking anecdotally, those students who I view as being addicted to social media, based on my observations, also have dispositions that would lead me to think they are less happy than those who are on their phones less. However, once again, it is impossible to state whether it is their use of social media, in terms of time spent or platforms used, that contributes to their dispositions.
As digital natives, it is unclear whether social media’s association with anxiety and depression is causal or a correlation. The studies’ sample size of 1787 people suggest that social media use exacerbates such issues; however, do they cause depression? I feel that a longitudinal study comparing the mental health of an experimental group of digital natives who utilize social media and a control group of non-social media uses would yield very interesting results.
Below are two interesting videos related to the topic. Additionally, the latter references the same study that I've referenced above.
