Study of Affective Forecasting Skills in Post-traumatic Stress Disorder

University Hospital, Lille97 enrolled

Overview

Post-traumatic stress disorder (PTSD) is associated with a marked tendency to have exaggerated and persistent negative beliefs and expectations about oneself or the world . Although posttraumatic stress symptoms have been shown to be associated with a tendency to negatively anticipate the future, affective forecasting skills (i.e., the ability to predict one's own emotional reactions in response to a future event) have never been explored in PTSD . The hypothesis that the PTSD is associated with a negative affective forecasting bias, characterized by a tendency to predict more intense emotional responses to future negative events.
