Abstract
Background: Emotional disturbances are central to post-traumatic stress disorder (PTSD) and shape how individuals anticipate and experience events.Objective: This study investigates affective forecasting and emotional experience among PTSD patients, trauma-exposed controls (TEC), and healthy controls (HC) using a novel virtual reality paradigm.Method: Eighty-six participants (30 PTSD, 28 TEC, 28 HC) rated their predicted and actual emotional responses (valence and arousal) to unpleasant, neutral, and pleasant virtual scenarios. Physiological measures included heart rate and skin conductance responses (SCR).Results: PTSD participants showed alterations in their affective forecasting and emotional experience, assigning significantly lower valence scores to pleasant and neutral scenarios and exhibiting amplified SCR to emotionally charged stimuli. Their arousal ratings for neutral stimuli were also more elevated compared to HC. In their forecasting, PTSD participants anticipated more positive - or less negative - emotions compared to what they experienced next.Conclusions: These findings reveal critical emotional processing differences in PTSD, both during affective forecasting and emotional experience, supporting cognitive models that emphasize biased processing of emotional information in this psychiatric condition.
期刊介绍：
The European Journal of Psychotraumatology (EJPT) is a peer-reviewed open access interdisciplinary journal owned by the European Society of Traumatic Stress Studies (ESTSS). The European Journal of Psychotraumatology (EJPT) aims to engage scholars, clinicians and researchers in the vital issues of how to understand, prevent and treat the consequences of stress and trauma, including but not limited to, posttraumatic stress disorder (PTSD), depressive disorders, substance abuse, burnout, and neurobiological or physical consequences, using the latest research or clinical experience in these areas. The journal shares ESTSS’ mission to advance and disseminate scientific knowledge about traumatic stress. Papers may address individual events, repeated or chronic (complex) trauma, large scale disasters, or violence. Being open access, the European Journal of Psychotraumatology is also evidence of ESTSS’ stand on free accessibility of research publications to a wider community via the web. The European Journal of Psychotraumatology seeks to attract contributions from academics and practitioners from diverse professional backgrounds, including, but not restricted to, those in mental health, social sciences, and health and welfare services. Contributions from outside Europe are welcome. The journal welcomes original basic and clinical research articles that consolidate and expand the theoretical and professional basis of the field of traumatic stress; Review articles including meta-analyses; short communications presenting new ideas or early-stage promising research; study protocols that describe proposed or ongoing research; case reports examining a single individual or event in a real‑life context; clinical practice papers sharing experience from the clinic; letters to the Editor debating articles already published in the Journal; inaugural Lectures; conference abstracts and book reviews. Both quantitative and qualitative research is welcome.
