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.

* Standardized psychiatric interview (Mini International Neuropsychiatric Interview MINI) * State-Trait-Anxiety Inventory (Spielberger, 1993) * Beck Depression Inventory (BDI-II, 1998) * Cognitive Emotional Regulation Questionnaire (Jermann \& al., 2006) Participant installation and testing: 2 stages (forecasting on a computer, and exposure in virtual reality) Task / affective forecasting: * Step 1: forecasting about one's own emotional responses regarding pleasant, neutral and unpleasant scenarios * Step 2: experience of the same scenarios in virtual reality

difference of arousal assessments measured using the Self-Assessment Manikin between the prediction and emotional experience phases
To compare the subjective affective forecasting bias between the PTSD group and the two control groups
Time frame: During the experimental task (2 hours)
subjective correlates of the affective forecasting bias associated with PTSD changes in: valence scores.
valence scores using the Self-Assessment Manikin (Likert-type scale ranging from 1 \[very unpleasant\] to 9 \[very pleasant\])
Time frame: During the experimental task (2 hours)
autonomic correlates of the affective prediction bias associated with PTSD: changes in the skin conductance response and heart rate.
changes in the skin conductance response and heart rate assessed using a BIOPAC (System, inc).
Time frame: During the experimental task (2 hours)
link between PTSD symptomatology and affective forecasting bias
PTSD symptomatology assessed using the Clinician-Administered PTSD Scale (CAPS-5) and PTSD Checklist for DSM-5 (PCL-5)
Time frame: During the experimental task (2 hours)
link and correlation coefficients between biases measured at the neurovegetative (changes in heart rate and skin conductance) and subjective levels (arousal and valence ratings from the Self-Assessment Manikin) in PTSD
Time frame: During the experimental task (2 hours)
link and correlation coefficients between affective forecasting bias and emotion regulation skills within each group
affective forecasting bias and emotion regulation skills, assessed using the Cognitive Emotional Regulation Questionnaire (CERQ)
