16 CBT View of Trauma PTSD = Anxiety disorder Cognitive, behavioural and physiological features Based on Behavioural and Cognitive Theories Fear is learned (Conditioning) Benign stimuli labelled incorrectly as dangerous Avoidance failure to learn corrective information Exposure Negative emotional reactions Guilt, anger and shame Assumptions and beliefs challenged Fail to organise traumatic experience successfully (make sense of it) 16 Cognitive Restructuring

17 EMDR View of Trauma PTSD = Incomplete information processing Networks containing related thoughts, images, emotions, and sensations Stored in an accessible and useful form Learning new associations are forged with material already stored in memory 17

18 EMDR View of Trauma Traumatic experience Memory stored dysfunctionally No appropriate associative connections With many elements still unprocessed Information processing is thought to occur when the targeted memory is linked with other more adaptive information Learning the experience is stored with appropriate emotions Used to appropriately guide the person in the future 18

19 A Model of Trauma Treatment A Phased Approach

20 A Model of Trauma Treatment Phase model of treatment of trauma Safety/Stabilization Trauma Processing (Re)integration/Meaning-making ~ Judith Herman 20

21 Safety / Stabilization Phase The general who wins the battle makes many calculations in his temple before the battle is fought. The general who loses makes but few calculations beforehand. ~ Sun Tzu

22 Safety/Stabilization Phase Reduce/manage dangerous behaviours /relationships, self harm, substance abuse Safety in therapeutic relationship Psychoeducation & skill building (e.g. breathing control, relaxation skills, positive self-statements) Enhance affect regulation & internal safety Symptom management (e.g. grounding, managing flashbacks, containment) 22

23 Trauma Processing Phase "The only thing we have to fear is fear it'self ~ FD Rosevelt Courage is not the lack of fear but the ability to face it." ~ Lt. John B. Putnam Jr.

24 Trauma Processing Phase Paced approach to addressing traumatic memories Integration of trauma into normal memory 24

25 (Re)integration / Meaning making phase Making light of the dark - Coral Anika Theill He who knows the why of his existence can bear almost any how - Nietzsche

26 (Re)integration / Meaning making phase Personality (re)integration & rehabilitation Reconnection, reconsolidation, restructuring Support patient in living a functional life Increase awareness of current safety Spiritual issues Enhance capacity for physical, sexual, emotional, interpersonal autonomy & intimacy Reclaiming their life! 26

27 7 Criteria for the resolution of trauma Mary Harvey 27 The physiological symptoms of PTSD have been brought within manageable limits The person is able to bear the feelings associated with traumatic memories The person has authority over the memories; can choose both to remember the trauma or to put the memory aside The memory of the traumatic event is a coherent narrative, linked with feeling The person s damaged self esteem has been restored The person s relationships have been reestablished The person has reconstructed a coherent system of meaning and belief that encompasses the story of the trauma
