یادگیری مهار ترس اختلالی، تداوم نشانه های اختلال استرس پس از سانحه را پیش بینی می کند

Results showed that greater startle responses during AB trials in individuals who discriminated between danger (AX+) and safety (BX−) during conditioning, predicted higher PTSD symptoms at 2 months and 9 months post-deployment. The predictive effect at 9 months remained significant after controlling for critical incidents during previous deployments and PTSD symptoms at 2 months. Responses to AX+ or BX− trials, or discrimination learning (AX+ minus BX−) did not predict PTSD symptoms. It is concluded that impaired fear inhibition learning seems to be involved in the persistence of PTSD symptoms.
