You’ve probably heard of PTSD, post-traumatic stress disorder. But what about its counterpart, post-traumatic growth?
The term was coined in the 90s to describe the positive psychological growth that researchers documented in people who had been through traumatic or highly stressful life events. Psychologists and sociologists conducting long-range studies on survivors of Hurricane Katrina – which hit 20 years ago and remains one of the most devastating natural disasters to hit the US – are continuing to learn more about it. 

So how do you measure post-traumatic growth? Can it co-exist with PTSD? NPR mental health correspondent Rhitu Chatterjee explains what scientists have found so far … and how it could help shape disaster relief efforts in the future.
