  1. 1. Assessing the efficacy ofSomatic Experiencing forreducing symptomsof PTSD
  2. 2. Is Trauma: Pathology or aninterruption on the path toResilience? QuickTimeª and a TIFF (Uncompressed) decompressor are needed to see this picture.
  3. 3. “Nature has instilled in all animals, including humans, a nervous system capable of restoring equilibrium. When self- regulating function isblocked or disturbed, trauma symptoms develop...” Peter Levine (Foundation for Human Enrichment, 2007)
  4. 4. Recovery, Resilience, and Chronic Symptoms QuickTimeª and a TIFF (Uncompressed) decompressor are needed to see this picture.
  5. 5. Some evidence for innate resilience… 60% of Dominant culture Americans experience a traumatic event. 8% of Dominant culture Americans meet the criteria for PTSD. In a cohort of 911 survivors number of number of positive emotions inversely correlated to the development of PTSD (Fredrickson, 2001). Resilient individuals have habits that increase resilience (Bonnano, 2004).
  6. 6. In this slide show we willaddress these four questions… • Why this study? • Why this study now? • How will the study be conducted? • What this study could show?
  7. 7. Why this study? Most theories used for psychological treatment start with the question, “How does pathology develop?” Somatic Experiencing starts from the questions: “What makes people resilient? Why don’t more people develop PTSD, trauma or other mental illness?”
  8. 8. Why this study? Cont... Paradigm Shift…3 levels: Resilience / affect regulation, deterministic chaos,. Bodymind Over the last ten years there has been a growing body of literature on resilience. Much of this literature matches the assumptions underling Somatic Experiencing theory. Preliminary studies show indications of SE being a short term effective treatment.
  9. 9. SE Studies: TFA (Trauma First Aid) Care Providers with Catholic Charities Post Katrina were given between one and two sessions. (N= 142) (Leitch, 2006). Significant increase in resilience was found (Leitch, 2006). Significantly less severe symptoms then control (Leitch, 2006). Both control and experimental had an increase of symptoms at follow up (Leitch, 2006). Tsunami Study: A few days after the session, 90% of participants showed complete or partial improvement in reported symptoms (Leitch, 2007). A few days after the session, 84% of participants exhibited complete or partial improvement in therapist observed symptoms (Leitch, 2007). All of the results should be interpreted with caution given the small sample size and lack of an equivalent comparison group (Leitch, 2007).
  10. 10. Why this study now? There is a growing interest in clinician driven research. Initial studies of the SE model have indicated that even one session can significantly reduce the development of symptoms of PTSD. The full SE treatment modality has not yet been studied. SE is a short-term treatment and thus would fit the current managed care model. The SE modality works with an individuals cultural, personal and familial contexts to increase psychological health.

  12. 12. Key concepts in SE Model… “Trauma is a natural normal part of life, not a mistake, a disease or aberration.” “Bodymind designed to heal intense experiences” “Works within clients, ‘range of resilience’” “Verbal / cognitive content is used to track activation not to access memories.” “SE model works with: Felt experience, physical sensation, motor patterns, and cognitive processes.” (Foundation for Human Enrichment, 2007)

  16. 16. Affect Regulation Affect Regulation: The ability to tolerate mange and return to homeostasis after a range of intensity of different emotional states. Self Regulation: The use of an affect regulation tool to manage high levels of affect. Auto Regulation: Well established, automatic or implicit regulation of affect. Co-Regulation: Regulation of affect through relationship or inter-subjective relatedness (Schore, 2008).
  17. 17. Affect Dysregulation Over Activated Sympathetic…  Physical: Increase heart rate, difficulty breathing, cold sweats, tingling, muscular tension, exaggerated startle response, difficulty with sleeping  Mental/Emotional: Anxiety attacks, rage outbursts, hyper vigilance, racing thoughts, worry (Foundation for Human Enrichment, 2007)
  18. 18. Affect Dysregulation Over Activated Parasympathetic…  Physical: Low energy, exaughstion, numbness, low muscle tone, poor digestion, low heart rate, blood pressure, poor immune function  Mental/Emotional: Depression, dissociation, apathy, disconnection in relationship, under responsive (Foundation for Human Enrichment, 2007)
  19. 19. How will this study be conducted? Between groups pre-test post-test matched control group design. Minimum N = 18 in each group ( N > 68 needed for optimum power.) Population: A convenience sample of adults who are currently living at COTS shelter. Matching Criteria: Years homeless, age, gender. Symptoms of depression operationalized as score on the Beck Depression Inventory. Symptoms of anxiety is operationalized as score on STAI
  20. 20. How will this study be conducted? Cont.Statistical Analysis: Repeated Measures Multivariate Profile Analisys will be used to asses all hypothesis. Descriminant Analysis will be used to assess all hypothesis.
  21. 21. How will this study be conducted? Cont. Some questions that remain:  Administering surveys two possibilities: A) senior participant at COTS shelter receives stipend, B) Find research assistants (undergrad volunteers).  Incentives for control group: A) Weekly raffle, B) $5 per week per control group member.
  22. 22. What could this study show? Whether and to what degree Somatic Experiencing is an effective modality for reducing symptoms of trauma. The effects of interactions of other therapeutic modalities such as: psychotherapy, case management, parenting classes, mindfulness based programs etc. The number of sessions that creates optimal change from Somatic Experiencing The type of Somatic Experiencing interventions that correlate the best with change in symptoms.
