Florida State University Robert O. Lawton Distinguished Professor Thomas Joiner, who co-authored a study published in the journal Clinical Psychological Science, said screen time should be considered a modern-day risk factor for depression and suicide.

“There is a concerning relationship between excessive screen time and risk for death by suicide, depression, suicidal ideation and suicidal attempts,” said Joiner, who conducted the research with psychology Professor Jean Twenge of San Diego State University. “All of those mental health issues are very serious. I think it’s something parents should ponder.”
