Examine whether and how to incorporate a cognitive-behavioral intervention for insomnia and nightmares with PTSD treatment to achieve the greatest treatment benefits in patients suffering from PTSD and sleep problems.

Evaluate the effectiveness of Cognitive Processing Therapy-cognitive only version (CPT-C) for combat-related PTSD when treatment length is adjusted to fit the individual needs of service members. Identify factors that can help predict how quickly an individual will respond to treatment. Determine how well CPT improves related problems (e.g., depression, difficulties in social and family functioning).

Evaluate in-person and Internet-based forms of cognitive behavioral therapy for insomnia with a military population. Determine the benefits of these interventions on improvement in sleep as well as on common co-morbid conditions such as depression, substance abuse, and PTSD symptoms.

To determine the impact of various factors, including cognitive flexibility, a genetic variation, and a protein secreted in the brain on the length of time it takes a patient to respond to treatment with Cognitive Processing Therapy. The ultimate goal is to use this information for developing improved strategies for preventing and treating posttraumatic stress disorder.

Evaluate whether adopting a pet dog from the San Antonio Humane Society as a supplement to usual care can reduce psychological distress and improve quality of life for Veterans with PTSD.

Explore the role of exercise in the treatment of symptoms of PTSD to see if treatment can be improved with exercise.

To conduct a comprehensive review of psychiatric aeromedical evacuations from Iraq and Afghanistan. Determine the long-term impact of those evacuations, identify areas of risk, provide recommendations to improve patient and aircrew safety, and yield data leading to improved care for patients, more efficient utilization of resources, and a reduction in medical discharges.

Test the hypothesis that early life stressors cause alterations in the expression of genes, specifically genes that regulate hypothalamic pituitary adrenal (HPA) axis activity, and that these genetic changes increase an individual’s susceptibility to PTSD following a traumatic event in later life. Potentially identify a molecular link between early environment, gene expression, and susceptibility to PTSD, a finding that could lead to intervention methods to reverse someone’s increased susceptibility to PTSD, perhaps with the use of medication.

Evaluate the interrelation of comorbid insomnia, pain and PTSD as seen in participants of other STRONG STAR randomized clinical trials focused on the treatment of combat-related PTSD. Perform an in-depth analysis to determine if the successful treatment of PTSD in turn reduces comorbid insomnia and pain, and whether comorbid insomnia and/or pain have a negative effect on participants’ response to PTSD therapy, providing insight to help providers tailor patients’ treatment to achieve the best possible outcomes.

Examine how alcohol use disorder impacts the effectiveness of selective serotonin reuptake inhibitor (SSRI) antidepressants used as the only FDA-approved medication for the treatment of PTSD. Specifically, identify patient characteristics predicting the response to SSRI treatment, which would give clinicians a valuable tool to assess who would or would not benefit from such treatment.
