New study links smartphone use in students with increased anxiety and bad grades | The Independent | December 2013
The research from Kent State University looked at 500 students, noting that “high frequency cell phone users tended to have a lower GPA [academic scores], higher anxiety, and lower satisfaction with life relative to their peers who used the cell phone less often.” …
The study also found that on average users would check their phones just six minutes after initiating a study session. This could propel a cycle of anxiety, with users feeling they are missing lead leading to lower academic performance leading to more worry.
