Treatment for Veterans With Military Sexual Trauma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effectiveness of Cognitive Processing Therapy (CPT) versus Present-Centered Therapy (PCT) in treating current post-traumatic stress symptoms associated with sexual assault that occurred while veterans were serving in the military.

Detailed Description
-----------------
This study is designed to provide insight into effective treatment of veterans with current Post Traumatic Stress Disorder [PTSD] that resulted from sexual assault that occurred during their active military duty [MST]. This issue is of critical importance, as (1) Congress mandated VA to provide counseling to veterans with sexual trauma. (2) Based on the national MST surveillance data of 1.7 million VA patients, 22% of women and 1% of men have experienced MST. (3) With 20,000 Operation Iraqi Freedom [OIF] veterans having already sought healthcare since deployment, VA will begin to serve a higher percentage of women from combat zones, where the epidemiology of sexual assault and the efficacy of conventional treatments are essentially unknown. Finally, (4) findings from our MST-Study of 270 women veterans strongly suggests that MST is clinically different from civilian adult or child sexual trauma, bringing into question whether conventional civilian-based treatment will be effective with MST veterans. Cognitive Processing Therapy (CPT) is a therapy developed to treat civilian rape-related PTSD. The efficacy of CPT has been shown with female civilians with sexual assault histories. However, there has not been any research examining the effectiveness of CPT in treating symptoms associated with sexual assault that occurs in military settings. The difference clinically between sexual assault in civilian and military settings is important, as revealed by our clinical experience and empirical findings. In working with veterans with MST for over 13 years we have noted that the assaults are often perpetrated by trusted military personnel and the victim is often without access to immediate treatment or care. Empirically, our research demonstrates that MST is associated with higher rates of PTSD compared to civilian sexual assault. The primary goal of the study is to evaluate the effectiveness of CPT treatment versus Present Centered Therapy (PCT) for PTSD and associated symptoms resulting from MST. The study objectives will be met by three levels of hypotheses. Hypotheses focus on the primary outcome (PTSD symptoms), confirmatory outcomes (depression symptoms, quality of life), and exploratory outcomes (cost and utilization). Based on the results of the study, we intend to produce an educational CD-ROM, which will include a training manual to educate practitioners on the use of the more effective treatment with veterans. It will be designed for administration by clinicians who represent a range of disciplines (e.g., psychologists, nurses, social workers) and levels of training (e.g., bachelor through doctoral degrees). This is a randomized controlled clinical trial involving veterans from the VA North Texas Healthcare System (VANTHCS). Data will be obtained from face-to-face interview and written questionnaires at baseline, treatment completion, 2-month, 4-month, and 6-month follow-ups. Patients will be randomized to one of two conditions (CPT or PCT). Patients will receive biweekly sessions of the respective individual therapy from trained therapists for a 6-week period (total of 12 sessions), followed by scheduled assessments. The primary endpoint is the CAPS score, a measure of PTSD severity. Secondary endpoints include anxiety, depression, quality of life, and healthcare utilization.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Arm 1<br>Participants receive 12 biweekly sessions of Cognitive Processing Therapy (CPT). | Behavioral: Cognitive Processing Therapy<br>* CPT is a cognitive therapy based on information processing theory and includes components which help the client to (a) access her or his memory of the event, (b) identify and experience her or his emotions until they have been extinguished, and (c) identify and challenge beliefs about the event itself and beliefs about self and the world which have been altered because of the rape.<br>* Other names: CPT;|
| Active Comparator: Arm 2<br>Participants receive 12 biweekly sessions of Present Centered Therapy (PCT). | Behavioral: Present-Centered Therapy<br>* PCT consists of general support and education focused on current issues in the patient's life. It emphasizes the focus on the individual's current life, and conceptualizes the problems addressed as manifestations of PTSD that, in some cases, may have been present for long periods of time. Emphasis is on problem solving and improving relationships. Connections are made between current problems and PTSD symptoms. PCT provides the emotional support for the trauma patient that is thought to help in recovery and helps the victim gain a better understanding of the nature of the patient's problems and connection with PTSD.<br>* Other names: PCT;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PTSD Checklist (PCL) | The PCL is a 17-item self-report measure that is commonly used in clinical and research settings. All 17 items are summed to compute a total score of PTSD symptomatology. Scores for the PCL range from 17-85, with 85 indicating severe PTSD symptomatology. The PCL has strong psychometric properties and mirrors the symptomatology of the DSM. | Baseline assessment and then 4, follow-up assessments: at treatment completion, 2-month post treatment, 4-month post treatment, and 6-month post treatment |
