Exposure Therapy for the Treatment of Post Traumatic Stress Disorder Peter W. Tuerk, Ph.D. Assistant Professor of Psychiatry and Behavioral Sciences MUSC; Post Traumatic Stress Clinical Team Charleston VAMC
Goals of the Talk • To become familiar with the symptoms andpsychological mechanisms of Posttraumatic Stress Disorder (PTSD). • To learn about the effective treatment of PTSD via Exposure therapy. • To learn about treatment via telehealth
NORMAL (not pathological) Post-Trauma Reactions (1-3 weeks) • Emotional:Shock, terror, irritability, blame, anger, guilt, grief, sadness, numbing, anhedonia. • Cognitive:Concentration impairments, confusion, nightmares, intrusive thoughts • Interpersonal:Marital / work conflicts, reduced intimacy, distrust, social withdrawal • Physical:Hyper arousal, fatigue, insomnia, GI distress
Normal Post-Trauma Reactions Take home point: Most people will experience some of these serious symptoms after a trauma or series of traumas. But most people will get better with simple support, obtained from family, friends, and community. Treatment is appropriate for those who still have problems 3-12 weeks later.
Rates of Diagnosable Psychopathology Following Trauma • Lifetime prevalence of PTSD among adult Americans at 6.8% • Rape: ~33% • Serious Physical assault: 20-33% • Oklahoma City Bombing: 33% (directly exposed) • Veterans from Iraq &Afghanistan : ~20% (45% have symptoms)
PTSD = Cluster of Symptoms:
PTSD Symptom Clusters • Re-Experiencing • Arousal • Avoidance
PTSD Symptoms • Re-Experiencing • •recurring intrusive thoughts or images of the • event. • recurring dreams about the event. • experience of severe anxiety when exposed to reminders of event, such as similar locations, noises, or smells. • acting or feeling as if the event were recurring (flashbacks).
PTSD Symptoms • Arousal • physiological reactivity when exposed to trauma cues. • problems falling/staying asleep. • increased irritability/ angry outbursts. • problems concentrating. • overly alert--always scanning environment. • elevated startle response. • FIGHT OR FLIGHT RESPONSE
PTSD Symptoms • Avoidance • avoidance of thoughts, feelings, or conversations related to trauma. • avoidance of people, places, or things that are reminders of the trauma. • reduction of interest/participation in previously enjoyable/important activities. • feelings of detachment/isolation • fear of, or inability to feel strong positive or negative emotions--numbing
PTSD Symptoms • Arousal • physiological reactivity when exposed to trauma cues. • problems falling/staying asleep. • increased irritability/ angry outbursts. • problems concentrating. • overly alert--always scanning environment. • elevated startle response.
PTSD Symptoms • Arousal (red also common in bereavement) • physiological reactivity when exposed to trauma cues. • problems falling/staying asleep. • increased irritability/ angry outbursts. • problems concentrating. • overly alert--always scanning environment. • elevated startle response.
PTSD Symptoms • Avoidance • avoidance of thoughts, feelings, or conversations related to trauma (or deceased). • avoidance of people, places, or things that are reminders of the trauma (or deceased). • inability to recall important aspects of event. • reduction of interest/participation in previously enjoyable/important activities. • feelings of detachment/isolation • fear of, or inability to feel strong positive or negative emotions--numbing

Evidence-Based Treatments • These are treatments that have been subjected to between groups study • Not merely well-marketed studies • All effective treatments for anxiety disorders such as PTSD involve some form of EXPOSURE Therapy, aimed at terminating avoidance.
Exposure Therapy for PTSD • Some efficacy exists for several types of psychological interventions for PTSD. • Strongest evidence exists for exposure-oriented • interventions • Number of rigorous studies 11-14 • Quality Reviews 15-16 • Quality of data • Strong effect sizes 11 Foa, Davidson & Frances, 1999 14 Schnurr et al., 2007 12 Foa & Rauch, 2004 15 Institute of Medicine, 2007 13 Foa et al., 2005 16 Bradley et al., 2005
Benefits of Exposure Therapy for PTSD Dissemination Efforts for Prolonged Exposure (PE) in the VA • Nationwide dissemination initiatives in PE • Multi-year rollouts • Four-day workshops, ongoing consultation and supervision • with regional trainers, emphasis on fidelity and high quality training. Preliminary results of PE with OEF/OIF veterans are promising17-19 17 Tuerk, Brady, Grubaugh, 2009 18 Rauch et al., 2009; 19 Tuerk, Grubaugh, Hamner, Foa, 2009

Exposure Therapy • Exactly what victim DOES NOT want to do • Patient must be active participant / collaborator. Must feel some control over progress of tx. • Often combined with some coping therapies, such as PMR or Breathing Retraining, but is not necessary .
Exposure Therapy How does it work? A large part of the process is due to Habituation. habituationis an example of learning in which there is a progressive diminution of behavioral response probability with repetition of a stimulus.
Exposure Therapy How does it work? A large part of the process is due to Habituation Processing and tolerating trauma specific stimuli promotes habituation to internal and external trauma cues.
