Exposure Therapy For Veterans With PTSD And Panic Attacks
Study Details
Study Description
Brief Summary
To evaluate the feasibility, acceptability and effectiveness of Multiple Channel Exposure Therapy-Veterans (MCET-V) as a treatment for returning service members with comorbid PTSD and panic disorder (PD). This study will examine the effectiveness of MCET-V by comparing it to Cognitive Processing Therapy, a standard PTSD treatment.

Detailed Description
With the increasing number of Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) Veterans returning from war-zone areas, many will experience anxiety disorders such as PTSD and comorbid problems. Currently, about one in every six OIF/OEF Veterans experiences PTSD and co-occurring PD. Although effective treatments exist for treating one or the other, we do not yet have treatments that can simultaneously target PTSD and PD. Thus, recent attention has focused on the development of multi-component treatments that simultaneously address PTSD and PD. This study is the first systematic investigation of a time-limited, multi-component cognitive-behavioral treatment for Veterans with specific comorbid anxiety problems. The purpose of the study is to evaluate the effectiveness of the multi-component cognitive-behavioral treatment in comparison to standard PTSD treatment in military personnel returning from active duty.

Outcome Measures
Primary Outcome Measures
- Change in PTSD Symptoms (CAPS) Between MCET-V and CPT Groups [Baseline, 1-week post-treatment and 3-month follow-up]
The CAPS is a clinician-administered assessment of the presence and severity of PTSD symptoms. Scores range from 0 - 136, with higher scores indicating greater symptom severity.
- Change in PDSS Scores Over Time for MCET-V and CPT Groups [Baseline, 1-week post, and 3-month follow-up]
The Panic Disorder Severity Scale (PDSS) is a clinician-rated assessment of the presence and severity of panic symptoms. Scores range from 0 - 28, with higher scores indicating greater symptom severity.

Comments | ||
Type of Statistical Test | Equivalence | |
Comments | To test if MCET is equivalent to CPT in decreasing PTSD symptoms, we test the equivalence of the proportion of patients whose CAPS scores decrease by 10 from baseline, by testing whether the difference in proportions between the 2 interventions ≤ to the equivalence margin δb of .20. Results are reported based on 3-month follow-up data. | |
Statistical Test of Hypothesis | p-Value | 0.30 |
Comments | The threshold for statistical significance is p <.05 and is not adjusted for multiple comparisons. | |
