Prevention: P h hPsychotherapy

• Psychological debriefingy g g– Single-session, individual or group crisis

intervention– Meant to reduce and prevent p

psychological sequelae following traumatic events by promoting emotional processing

– Focus is on the present reaction of individuals shortly after a traumatic experience

– Use is no longer advocated; studies have revealed that it is ineffective -- or even potentially harmful

Prevention: P h hPsychotherapy

• Cognitive-behavioral therapy (CBT)Cognitive behavioral therapy (CBT)– Has shown considerable promise in

cases involving acute stress disorder or high levels of distress

– Early intervention CBT involves 60-90 minute weekly sessions over 5-12minute weekly sessions over 5 12 weeks

– Evidence for efficacy in preventing PTSD is strongest for those exposed to accidents (e.g., MVAs); less convincing for those exposed to interpersonalfor those exposed to interpersonal violence (e.g., rape)

Prevention: Ph hPharmacotherapy

• Benzodiazepines have not been b fi i l i di i i ibeneficial in studies examining prevention of PTSD

• While RCTs have not found that propranolol can reduce the rate of PTSD, a cohort study and a RCT revealed a reduction in PTSD symptom levels and

d d h i l i l ti it treduced physiological activity to reminders of trauma

• Acute IV hydrocortisone was superior to l b i ti PTSD t iplacebo in preventing PTSD symptoms in

medical patients with septic shock or those undergoing cardiac surgery
