Cognitive reappraisal training before a stressful event can reduce distress from intrusive memories, potentially serving as a cognitive prophylaxis against trauma symptoms. This study investigated the benefits of reappraisal training administered prior to a stressor.
Area of Science:
- Psychology
- Cognitive Neuroscience
Background:
- Intrusive memories are a key symptom of posttraumatic stress disorder (PTSD).
- Dysfunctional appraisal of these symptoms can worsen PTSD.
- Previous research suggests reappraisal training after a stressor reduces symptoms.
Purpose of the Study:
- To investigate if reappraisal training administered before a stressful event is beneficial.
- To determine if cognitive bias modification for appraisal (CBM-App) training can prevent trauma-related symptoms.
Main Methods:
- Participants underwent positive or negative CBM-App training using scripted vignettes.
- Participants were then exposed to a traumatic film.
- Outcomes measured included post-training appraisals, changes in the Post Traumatic Cognitions Inventory (PTCI), and intrusive symptom diaries.
Main Results:
- CBM-App training successfully induced congruent appraisal styles.
- Positive reappraisal training led to less distress from intrusive memories compared to negative training.
- The induced appraisal bias had a partial effect on PTCI scores.
Conclusions:
- CBM-App training shows benefits when applied before a stressful event.
- This training may act as a cognitive prophylaxis against trauma symptoms.
- Limitations include participant-referenced PTCI assessments and lack of a control group.
