James J. Lickel, Ph.D. & Richard Machotka William S. Middleton Memorial Veterans Hospital.
Cluster of symptoms that follow exposure to a potentially traumatic event Marked by clear cognitive, behavioral, and physiologic changes Can be chronic if untreated and greatly affect quality of life NOT a sign of weakness, lack of resiliency, or lack of preparation
At least 50% of population will experience “trauma” in their lifetime, most more than once Most will experience symptoms of PTSD initially, but won’t go on to develop PTSD There are gender, racial, and ethnic differences in exposure to trauma and development of PTSD
Negative alterations in thoughts and mood Difficulty remembering aspects of event Exaggerated beliefs or expectations about self, others, or the world (“No one can be trusted”) Loss of interest in past enjoyable experiences Feeling detached or cut-off from others Emotional numbness
Common Reactions to Trauma Re-experiencing Intrusive thoughts Strong emotions when triggered by reminder Avoidance Of stimuli present at time of trauma Hyperarousal Increased vigilance Anger Adaptive Function Easily accessed memories that warn of danger Reduces likelihood of repeated exposure to threat Increased attention to threat & Display of preparedness

Psychological Processes Involved in Development of Symptoms of PTSD “IEDs can be planted anywhere.” “I must have done something to ask for this.” “I trusted this man, it is my fault.” “He died on my watch.” “Markets and crowds are unsafe.” “You can never let your guard down.” Cognitive Change

Current research suggests a number of physiological differences found in people diagnosed with PTSD ◦ Hormonal differences: Abnormalities in stress response hormone levels (glutamate, GABA, Norepinephirne, CRF. Responsible for preparing our bodies to respond to threat - > constant state of readiness ◦ Brain differences: Smaller hippocampus (Inhibition of HPA axis and processing of memories) Over-reactive amygdala (decreased threshold for “firing”) Under-reactive prefrontal cortex (inhibits amygdala and interferes with working memory)

Anxiety increases Avoidance This situation is dangerous; I got out just in time; Something awful could have happened Anxiety Time Courtesy of Sally Moore, Ph.D.
Stop avoidance Anxiety decreases on its own This situation was not as dangerous as it felt; I can tolerate anxiety; I don’t have to avoid to feel better. Anxiety Time Courtesy of Sally Moore, Ph.D.
Psychoeducation Trauma account (evidence of efficacy without) Identification of “Stuck Points” Cognitive restructuring
Psychoeducation Impact Statement “Stuck Points” ◦ Those things trauma survivors say to themselves about the trauma/self/others/world. ◦ Examples “It was my fault. I could have prevented it.” “I am a monster for what I did during the war.” “I should have been able to save everyone.” “The world is an incredibly dangerous place.”
It is how we THINK about the event, not the event itself, that often causes us lasting distress ◦ Ex: Friend passing by A-B-C Model – core of CPT A = EventB = Belief/Thought C = Feeling Firefight resulting in casualty I let my friend die Guilty Sad
Sessions 4 - 6: Write/Read Trauma Account Sessions 6 - 7: Cognitive Work in depth Sessions 8 – 12: Explore Themes of Safety, Trust, Power/Control, Esteem, and Intimacy Continue to read account throughout course of treatment for purposes of exposure Session 12: Review of 2 nd Impact Statement
In general, trauma-focused therapies more effective than non-specific/supportive interventions and no treatment. No consistent differences observed between trauma- focused therapies, though there is limited research regarding this. Initial response rates of EBP for PTSD range between 40- 92%. Regular therapy attendance and family support associated with more positive outcome Initial severity of symptoms and benzodiazepine use associated with poorer outcome.
