Content
Post-traumatic stress disorder (PTSD) Trauma therapy In detail: Expressive writing (J. Pennebaker)
Post-traumatic stress disorder (PTSD) Relatively new anxiety disorder (first appearance in DSM-III in
1980) Anxiety that follows a traumatic event This event poses a threat to the individual’s life or lives of othersSymptoms: Re-experiencing of feelings related to the event (such as
intrusive memories, thoughts and images related to the event) Avoidant behaviour (such as denial and emotional numbing) Arousal (such as hypervigilance for trauma-related information) Also: sadness, guilt and anger (Shore et. al., 1989)
PTSD
Appears seldom alone but with other disorders or additional diagnoses (Bleich et al., 1997)
PTSD is a controversial inclusion in DSM-IV because its validity has been challenged
Some researchers point to the ease with which PTSD symptoms can be faked
Study: Burges and Mc Millan, 2001 Participants of a night class were asked to generate symptoms of
PTSD from a vignette The class also read a standard PTSD symptom checklist (or one
containing bogus items) and were asked to complete the measure as if they were suffering from PTSD
One percent of the sample self-generated PTSD symptoms that met DSM-IV criteria, despite 40 per cent claiming that they had witnessed a traumatic event
When given the symptom checklist, however, 94 % met the criteria for PTSD
Participants correctly identified around 38 % of the bogus items
Events and reference studiesEvent Reference studies
Rape Green, 1994
Road traffic accidents Stallard et al., 1998; Murray et. al., 2002
Bank robberies Kamphuis and Emmelkamp, 1998
War Fontana and Rosenheck, 1993
Natural or human-made disaster
Freedy et al., 1994
Prevalence
Prevalence rate is around 25-30 % in the general population
Rape is associated with the greatest prevalence
Onset of the disorder may be delayed by many years (Blank, 1993)
Study: Dunmoore et al., 1999 Determining the factors which are associated with the onset of PTSD
and those who help maintain it They analysed data from 96 victims of physical or sexual assault Some factors were common to both onset and maintenance whereas
others where specific to onsetFactors associated with both: appraising the event and the consequences of the event (dwelling on
the assault and its aftermath) Poor coping strategies (such as avoidance)Factors related to onset: Feeling detached during the assault Being unable to perceive positive responses from othersThese cognitive factors may prevent recovery by encouraging poor coping
strategy or by generating a sense of immediate threat
Other findings
Joseph et al., 1994: although crisis support was a good predictor of psychological well-being of survivors after the disaster, feelings of helplessness during the disaster, and bereavement, predicted the frequency of intrusive thoughts about the disaster
Joseph et al., 1997: negative attitude towards expressing emotion (for example, agreeing with statements such as, ‘I think getting emotional is a sign of weakness’) were associated with an increased number of PTSD symptoms
Study: Clohessy and Ehlers, 1999 Asked 56 ambulance drivers in the UK to describe the most
distressing aspects of their work and administered questionnaires which tapped their ability to cope with this distress and the degree to which the thoughts about the distress were intrusive
21 % of the sample met DSM-IV criteria for PTSDPredictors of the severity of the post-traumatic stress: Poor coping strategy Efforts to suppress intrusive thoughts Dwelling on previous distressing events
Post-traumatic stress disorder (PTSD) Horowitz’s model (1979, 1986): Trauma-related information is processed
because of a mechanism called completion tendency.
Completion tendency: need for new information to be integrated into existing patterns of thought and memory
Power and Dalgleish (1997)
Stunned reaction to the traumatic event Experience of information overload as the individual realises the
enormity of the trauma as it ‘sinks in’. Such information cannot be accommodated by existing mental
schemata Defence mechanism such as denial and numbing are a means of
coping with this lack of accommodation Completion tendency, however, insists on keeping the memory
of the event alive through flashbacks and nightmares Anxiety results from the vacillation between these two processes:
defence mechanisms and completion tendency

Treatment
Debriefing (Deahl et al., 1994): effective Drug treatments (O’Brien and Nutt, 1998): mixed
success Exposure (Foa and Meadows, 1997): effective Other techniques: Expressive writing (James
Pennebaker) For an overview: Shalev et al., 1996; Foa and
Meadows, 1997
What therapies treat PTSD symptoms by integrating cognitive, emotional and
sensory/motor experience? Noted trauma authority and author Bessel van der Kolk has
written, "... re-living trauma often occurs in the form of physical sensations that precipitate emotions of terror and helplessness. Learning how to manage and release these physical sensations from trauma-based emotions is an essential aspect of the effective treatment of PTSD.”
There are now a number of schools of what has come to be known a somatic psychotherapy which utilize cognitive, emotional and sensory/motor experience to treat PTSD. These include:

There are now a number of schools of what has come to be known a somatic psychotherapy which utilize cognitive, emotional and sensory/motor experience to treat PTSD. These include:
EMDR therapy
combines a somatic therapeutic approach with eye movements or other forms of rhythmical stimulation, such as hand taps or sounds that stimulate and integrate the left and right hemispheres of the brain. See Helpguide's EMDR Therapy: A Guide to Making An Informed Choice for more information and practitioner listings.
Somatic experiencing
is a therapy developed by Peter Levine that incorporates observations of how animals treat themselves following traumatic events and focuses on restoring normality to the stress response. According to Levine, the symptoms of trauma result from highly activated incomplete biological response to threat. Wild animals have the ability to “shake off” this excess energy. By enabling humans to do the same, trauma can be healed. See Helpguide's Panic, Biology, and Reason: Giving the Body Its Due in the references & resources below for more information and practitioner listings.
