Worrying PTSD study

Researchers collected baselines scores of participants’ neuroticism, and followed up at three, five and 10 years. Half the participants experienced a traumatic event during the study period. Those who scored higher on the neuroticism scale at the study onset were significantly more likely to end up among the 5% who developed PTSD.

The study is the first to prospectively link personality to PTSD before the traumatic experience has occurred. 

Major depression at baseline was a strong predictor of subsequent PTSD, but the association between neuroticism and PTSD was not found in that subgroup.
