Brief Summary

The goals of this project are

• 1) to evaluate the effectiveness of a CBT treatment module addressing the mental health and functional impact of killing in the war zone,
• 2) to gather data on Veteran stakeholders' perceptions of acceptability and feasibility of the CBT treatment module, which would be used to further refine the intervention, and
• 3) to gather data on clinician stakeholders' perceptions of acceptability and feasibility of the CBT treatment module, which would be used to ensure that the module could be easily integrated into EBT for PTSD.

Detailed Description

Background: There is mounting evidence that Veterans from multiple eras who kill in war are at increased risk for posttraumatic stress disorder (PTSD), alcohol abuse, suicide, and functional difficulties after returning home. Despite high rates of exposure to killing and associated maladaptive responses, the military and VA do not routinely assess exposure to killing, which could assist with prevention and treatment efforts. Furthermore, the impact of killing is not currently addressed as a component of evidence-based treatment (EBT) for PTSD. In fact, in the current system, a Veteran can receive PTSD evaluation and evidence-based treatment without ever being asked about killing and its impact. Some researchers have cautioned against using one type of PTSD treatment, one commonly used in the VA, suggesting that it may be harmful for these patients. Consequently, it is possible that failing to directly treat the mental health impact of killing could result in inappropriate treatment, cause harm to Veterans, and cost lives.

Objectives: Our first aim is to evaluate the effectiveness of a CBT treatment module addressing the mental health and functional impact of killing in the war zone, which would be added onto existing EBT for PTSD. Our second aim is to gather data on Veteran stakeholders' perceptions of acceptability and feasibility of the CBT treatment module, which would be used to further refine the intervention. Our third aim is to gather data on clinician stakeholders' perceptions of acceptability and feasibility of the CBT treatment module, which would be used to ensure that the module could be easily integrated into EBT for PTSD.

Methods: The investigators propose a 12-month pilot, cross-sectional Hybrid Type 2 study, given that The investigators will be adding a treatment module to existing EBT for PTSD. The investigators will conduct a randomized, controlled effectiveness trial to better understand if the six-week treatment module addressing the impact of killing has added benefit, compared to PTSD treatment as usual (N = 50). The investigators will employ a concurrent design mixed method study to test the perceptions of Veteran stakeholders who receive the treatment module, obtaining ratings of acceptability and feasibility through self-report measures and interviews. The investigators also will interview clinicians who provide EBT for PTSD, and interviews will be guided by Roger's five intrinsic characteristics, as outlined in his Diffusion of Innovations Theory.

Impact: Through involving Veteran and clinician stakeholders, the main impact of this project will be to obtain information that will assist in revising the CBT treatment module and help prepare for implementing the module in already existing settings, where EBT for PTSD is provided.

Eligibility Criteria

Inclusion Criteria

• Combat Veterans ranging in age from 18-70 years will be recruited to participate in this study. Combat veterans ranging in age from 70 to 90 years will also be considered for enrollment in the study on a case-by-case basis.
• Veterans will need to endorse having taken a life in a war zone context, to meet criteria for PTSD, and to have received some prior treatment for PTSD to be included in the study.
• Participants in current PTSD treatment will not be excluded; however, if receiving medications, they will need to be stabilized on current medications for at least one month.
• If receiving Prolonged Exposure (PE) or Cognitive Processing Therapy (CPT), the two treatments the VA recognizes as evidence-based treatment for PTSD, individuals will need to wait two weeks after they have completed the treatment in order to enroll in the study, and new baseline measures will be obtained at that time.

Exclusion Criteria

• Potential participants will only be excluded if they meet current or lifetime criteria for a psychotic disorder.

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 70 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
