In March 2019, Dr. Jean Twenge published multiple pieces based on her research:
But a new analysis of a large representative survey reinforces what I – and others – have been saying: The epidemic is all too real. In fact, the increase in mental health issues among teens and young adults is nothing short of staggering.
Recent trends are startling. From 2009 to 2017, major depression among 20- to 21-year-olds more than doubled, rising from 7 percent to 15 percent. Depression surged 69 percent among 16- to 17-year-olds. Serious psychological distress, which includes feelings of anxiety and hopelessness, jumped 71 percent among 18- to 25-year-olds from 2008 to 2017. … the suicide rate among 18- to 19-year-olds climbed 56 percent from 2008 to 2017.
From 2009 to 2017, rates of depression among the ages of 14 to 17 in the U.S. jumped more than 60%, and emergency-room visits for self-harm and suicidal thoughts in this age group also increased sharply.
