Predictors of PTSD from Predictors of PTSD from Meta-analysesMeta-analyses
• Brewin et al. (2000)– Trauma severity– Lack of social support– Additional life stress– Gender– Age at trauma– Race– Education– Prior trauma– Psychiatric history
• Ozer et al. (2003)– Prior trauma – Prior psychological
adjustment– Family history of
psychopathology– Perceived life threat– Posttrauma social
support – Peritraumatic emotional
response– Peritraumatic
dissociation

• Random Digit Dialing, nationally representative sample of 560 US adults between 9/14/01 – 9/16/01
• 44% of adults had a “substantial stress reaction”
• Predictors: Gender (female), race/ethnicity (non-white), prior mental health problems (yes), distance from WTC (closer), hours of TV viewing (more)

Acute ReactionsAcute Reactions• Random Digit Dialing, representative sample of
1008 adults living south of 110th St. in Manhattan between 10/16/01 – 11/15/01
• Overall incidence of PTSD was 7.5%, but 20% for those living south of Canal St.
• Predictors: Gender (female), race/ethnicity (non-white; trend), stressors in past year (more), social support (less), distance of residence from WTC (closer), directly witnessed events (yes), loss of possessions (yes), involved in rescue (yes), lost of job (yes), symptoms of panic attack during or soon after event (yes)

Natural RecoveryNatural Recovery• National probability sample of 3496 US adults
received Web-based survey 9-23 days after 9/11; a random subsample of 1069 participants living outside of New York City received a second survey two months following 9/11, and third wave (n = 787) was completed six months after 9/11
• 17% of participants had PTSD two months after 9/11, compared to 5.8% at six months
• Predictors: Gender (female), prior physician diagnosis of depression or anxiety disorder (yes), marital status (separated), physical illness (yes), severity of exposure to attacks (greater severity), early disengagement of coping efforts (yes)

Acute Stress Disorder (ASD)Acute Stress Disorder (ASD)
• A. Exposure to a traumatic event• B. Dissociation either while experiencing or
after experiencing the trauma (at least 3):– Numbing, detachment, absence of emotional
responsiveness– Reduction in awareness of one’s surroundings– Derealization – Depersonalization– Dissociative amnesia
![Page 22: Evidence-Based Treatment for Posttraumatic Stress Disorder: Preparing for the Aftermath of Disaster Shawn P. Cahill, Ph.D. Center for the Treatment and](https://reader036.vdocuments.site/reader036/viewer/2022062801/56649e425503460f94b34f30/html5/thumbnails/22.jpg)
ASD (cont’d)ASD (cont’d)• C. Reexperiencing the trauma through recurrent
images, thoughts, dreams, illusions, flashbacks, distress upon exposure to reminders of the trauma (at least 1)
• D. Marked avoidance of stimuli that arouse recollections of the trauma
• E. Marked symptoms of anxiety or increased arousal
• F. Disturbance causes functional impairment• G. Lasts a minimum of 2 days, a maximum of 4
weeks, and occurs within 4 weeks of the trauma
![Page 23: Evidence-Based Treatment for Posttraumatic Stress Disorder: Preparing for the Aftermath of Disaster Shawn P. Cahill, Ph.D. Center for the Treatment and](https://reader036.vdocuments.site/reader036/viewer/2022062801/56649e425503460f94b34f30/html5/thumbnails/23.jpg)
Why ASD?Why ASD?
• Recognize posttraumatic stress can occur in the acute trauma phase
• Permit the prediction of chronic PTSD– ASD emphasizes the role of dissociative
symptoms in preventing long-term recovery
![Page 24: Evidence-Based Treatment for Posttraumatic Stress Disorder: Preparing for the Aftermath of Disaster Shawn P. Cahill, Ph.D. Center for the Treatment and](https://reader036.vdocuments.site/reader036/viewer/2022062801/56649e425503460f94b34f30/html5/thumbnails/24.jpg)
Criticisms of ASDCriticisms of ASD• Insufficient evidence to support the necessity
of dissociation in the acute trauma response• Questionable practice to introduce a new
diagnosis in order to predict another diagnosis
• Concern about pathologizing transient stress reactions
• Questionable practice to distinguish between two diagnoses with similar symptom clusters on the basis of duration

ConclusionConclusion
• Reaction to mass trauma (e.g., 9/11) similar to reactions to other types of traumas (e.g., rape, physical assault, motor vehicle accidents, etc.)
• Effect of media exposure and reparative acts

• Cognitive Behavior Therapy– Exposure therapy – Stress inoculation training (SIT)– Cognitive therapy (CT, CR, CPT)– Combinations of exposure therapy with SIT and/or CR– EMDR

Summary of MedicationSummary of Medication
• Substantial placebo effect
• Significant medication effect
• Residual symptoms– Many non-responders– Many responders still experience significant
symptoms
![Page 41: Evidence-Based Treatment for Posttraumatic Stress Disorder: Preparing for the Aftermath of Disaster Shawn P. Cahill, Ph.D. Center for the Treatment and](https://reader036.vdocuments.site/reader036/viewer/2022062801/56649e425503460f94b34f30/html5/thumbnails/41.jpg)
• Anxiety management or stress inoculation training (SIT)
• Cognitive therapy (CT)
• Exposure therapy– As primary intervention
– Combined with SIT or CT
• EMDR

Cognitive TherapyCognitive Therapy
• A set of techniques that help patients change their negative, unrealistic cognitions by:
– Identifying dysfunctional, unrealistic, or unhelpful cognitions (thoughts and beliefs)
– Challenging these cognitions
– Replacing these cognitions with more functional, realistic, or helpful cognitions
![Page 44: Evidence-Based Treatment for Posttraumatic Stress Disorder: Preparing for the Aftermath of Disaster Shawn P. Cahill, Ph.D. Center for the Treatment and](https://reader036.vdocuments.site/reader036/viewer/2022062801/56649e425503460f94b34f30/html5/thumbnails/44.jpg)
A set of techniques designed to help
patients confront their feared objects,
situations, memories, and images
(e.g., systematic desensitization,

Efficacy of CBT: SummaryEfficacy of CBT: Summary
• Several forms of CBT are efficacious• Treatment gains generally maintained at
follow-up (up to 1 year)• Some patients show only a partial or no
response (residual symptoms)• Combined treatments (PE/SIT, PE/CR) not
significantly more efficacious than individual treatments (PE, SIT, CR)
• CBT and SSRI of comparable efficacy

Strategies for Improving Strategies for Improving Treatment OutcomeTreatment Outcome
• Combining treatments within the same treatment modality (i.e., psychotherapy or medication)– Adding SIT or CR to PE (hasn’t worked very well)– What about combining medications?
• Extending duration of treatment• Combining treatments across treatment modalities
– SSRI+CBT (e.g., adding CBT to medication)

Improving Outcome: SummaryImproving Outcome: Summary
• Strategies that haven’t worked:– Combining separately effective CBT programs
• Strategies that have worked:– Extending treatment (SSRI and CBT)– Augmenting SSRI with CBT for SSRI partial
responders
• Strategies to be investigated:– Augmenting CBT with medication– Augmenting SSRI with other medications
