Tracking trauma symptom changes over two years improves prediction of long-term mental health outcomes

Source Summary

A Tohoku University study published in JAMA Network Open on August 14, 2026, found that changes in trauma symptoms during the first two years after a disaster are a better predictor of long-term mental health than a single assessment shortly after the event. The research examined survivors of the Great East Japan Earthquake, many of whom continue to experience psychological effects nearly 15 years after the disaster.
