5 important questions on Cognitive model of PTSD by Ehlers and Clark
What are the key components outlined in Ehlers and Clark's (2000) cognitive model of PTSD as depicted in the diagram?
- Cognitive processing during trauma
- Negative appraisals of trauma and its sequelae
- Nature of trauma memory
- Matching triggers for the traumatic memory
- Perceived current threat which includes intrusions, arousal symptoms, and strong emotions
- Strategies intended to control the perceived threat and symptoms
How are the relationships between characteristics, cognitive processing, appraisals, memory, triggers, threats, and strategies depicted in the cognitive model of PTSD?
- Cognitive processing during trauma influences both the nature of trauma memory and the negative appraisals of trauma.
- Memory and appraisals contribute to matching triggers and the perception of current threat.
- The perception of a current threat contributes to strategies intended to manage threat and symptoms.
- Arrows indicate the direction of influence between components.

How does the brain function differently under stress, affecting the development of PTSD?
- Sensory aspects dominate, with victims focusing on escaping or distancing themselves
- Victims often remember surroundings but not the weapon used
- There are more intrusions post-trauma, with random frames of trauma without context
- Activating the visuospatial sketchpad after a trauma prevents PTSD development
What are the first-line treatment recommendations for PTSD?
- Cognitive Behavioral Therapy (e.g., prolonged exposure therapy)
