Post-traumatic stress disorder: evaluation of a behavioral treatment program

Area of Science:

• Psychiatry
• Clinical Psychology
• Trauma Studies

Background:

• Post-traumatic stress disorder (PTSD) is a debilitating condition often treated with exposure therapy.
• The comparative effectiveness of imaginal versus real-life exposure in PTSD treatment requires further investigation.

Purpose of the Study:

• To compare the efficacy of imaginal exposure followed by live exposure versus live exposure followed by imaginal exposure in patients with PTSD.
• To assess the long-term impact of these therapeutic sequences on PTSD symptoms and general health.

Main Methods:

• Randomized controlled trial with 14 patients diagnosed with PTSD.
• Two groups received four weekly sessions of either imaginal or live exposure, in a counterbalanced order.
• Outcome measures included PTSD-specific and general health assessments at post-treatment and 12-month follow-up.

Main Results:

• Both treatment sequences resulted in significant improvements in PTSD symptoms and general health.
• Further significant gains were observed at the 12-month follow-up on 7 out of 12 measures.
• Live exposure demonstrated superior improvement in phobic avoidance, regardless of its order in the treatment sequence.
• Clinical improvement ranged from 65-80% reduction in target symptoms.

Conclusions:

• Both imaginal and live exposure are effective therapeutic components for PTSD.
• The order of exposure therapy may influence specific symptom reduction, particularly phobic avoidance.
• Comprehensive exposure, including self-exposure homework, is crucial for effective PTSD management.
