Post-traumatic stress disorder (PTSD) is a psychological disorder that results from exposure to trauma, such as being involved in a car accident or witnessing a suicide.
According to the DSM-5, the most recent edition of the Diagnostic and Statistical Manual of Mental Disorder, the symptoms of PTSD include:
- Exposure to threatened or actual injury, sexual violence, or death.
- Intrusion symptoms (e.g., intrusive memories or dreams about the trauma).
- Active avoidance of feelings, thoughts, memories, or external reminders of the trauma.
- Negative mood and cognitive changes (e.g., feelings of terror, thoughts of shame, and self-blame).
- Heightened arousal (e.g., startling easily, having sleep difficulties, experiencing concentration problems).
PTSD Treatments include medications and psychological interventions. In this article, we look at three effective psychological interventions for PTSD: cognitive behavioral therapy, cognitive processing therapy, and prolonged exposure therapy.
Cognitive-behavioral therapy (CBT) is based on the idea that thoughts, behaviors, and feelings are interconnected; more importantly, that changes in one may result in changes in the others.
For example, individuals who have been traumatized tend to catastrophize (e.g., “Things will never get better”), which increases their anxiety and avoidance. Replacing these cognitive distortions with more accurate thoughts (e.g., “Things are tough now but have gotten better before and will likely again”) can have a positive influence on both emotions (i.e. lowering anxiety) and behaviors (i.e. reducing avoidance).
So, in therapy, patients learn to identify and challenge inaccurate assumptions about themselves and the world and to replace erroneous beliefs with more realistic ones.
The treatment may also include mind-body interventions, such as relaxation training and mindfulness.
Cognitive processing therapy
Cognitive processing therapy (CPT), a form of cognitive-behavioral therapy, is another effective PTSD treatment.
CPT is a highly structured treatment: Patients are first educated about the treatment model. They are then asked to write an “impact statement” regarding the meaning of the traumatic incident and later instructed to write a detailed description of the worst traumatic event and share it with the therapist.
The therapist then uses Socratic questioning to help patients identify and challenge “stuck points,” which are distorted beliefs related to the trauma (e.g., “What happened was all my fault”).
During the second half of the treatment, patients are asked to focus, each week, on a different theme (e.g., trust, safety, power, esteem, intimacy), and to replace extreme or distorted beliefs related to the selected theme with more balanced thoughts.
In the last session, progress is assessed by comparing the initial impact statement with a newly written one.
PTSD treatment Prolonged exposure therapy
Another effective psychological PTSD treatment is called prolonged exposure (PE).
PE, which is also a form of cognitive-behavioral therapy, commonly consists of several components: psychoeducation (about PTSD treatment), breathing retraining (to reduce anxiety, to lower physiological arousal), and two types of exposure called imaginal and real-life exposure, which are described below.
Imaginal exposure requires repeatedly confronting trauma memories (e.g., memories of a motor vehicle accident).
The patient is first instructed to recount the traumatic memory in the present tense. Then, following each imaginal exposure, the therapist helps the patient to make sense of the traumatic memory and to learn that these thoughts are dangerous.
Similarly, real-life exposure involves confronting situations and activities (e.g., driving) that are avoided because they remind the individual of the trauma. Though an understandable coping mechanism, avoidance will maintain the PTSD symptoms.
Exposure exercises, in contrast, teach the patient the avoided situation or activity is not so dangerous, he or she can tolerate the distress, and that the fear will eventually subside.
