DSM Trauma exposure (criterion A)
Exposure to actual or threatened death, serious injury or sexual violence in one or more of the following ways:
- Directly experiencing the traumatic event
- Witnessing, in person, the event as it occured to others
- Learning that the traumatic event occurred to a close family member or friend.
- Experiencing repeated or extreme exposure to aversive details of the traumatic event. (e.g. First responders collecting human remains.)
Sternocostoclavicular hyperostosis and PTSD
SCCH is a disease that often takes long to diagnose. Because of this, patients often have more PTSD symptoms with this illness compared to other illnesses.
Conclusions on the A-criterion of PTSD
- Relationships between severity of event and symptoms
- Events are distant causes, true causes lie within the person (vulnerability, processing) and person environment interaction
- Demarcation is arbitrary/practical/political rather than objective/scientific
- We don’t do this in other disorders
Problems with A-criterion
- Medicalizes normal stress
- A-criterion doesn’t suffice: demarcation trauma, reliable reporting/measurement of trauma and emotions, relation trauma to PTSD and other disorders.
- Overlap with other disorders: reeexperiencing, avoidance, negative thoughts and emotions, hyperarousal
Proposed changes to PTSD criteria
- Abolish Criterion-A
- Less (and most characteristic/specific) symptoms
Reexperiencing intrusion criteria according to Brewin
- Recurrent distressing dreams related to an event now perceived as having severely threatened someone’s physical or osychological well-being, from which the person wakes with marked fear or horror, or
- Repeated daytime images related to an event now perceived as having severely threatened someone’s physical or psychological well-being, experienced as recurring in the past and accompanied by marked fear or horror.
Avoidance criteria according to Brewin
Avoidance should be present in the past month. Either:
- Efforts to avoid thoughts, feelings, conversations, or internal reminders associated with the reexperienced event, or
- Efforts to avoid activities, places, people, or external reminders associated with the reexperienced event.
Arousal criteria according to Brewin
Hyperarousal should be present most days in past month. Either:
- Hypervigilance, or
- Exaggerated startle response.
