- Brief Summary
The overarching aim of this proposal is to research whether meditation-based treatments are effective in decreasing posttraumatic stress disorder (PSTD) symptoms in veterans, which complementary and alternative (CA) treatments are most effective, and how individual differences predict treatment efficacy.
- Detailed Description
The overarching purpose of this study is to assess the impact of CA interventions on posttraumatic stress symptoms in veterans with PTSD. Twenty percent of the approximately 2 million veterans returning from Iraq and Afghanistan ("Operation Iraqi Freedom" or OIF and "Operation Enduring Freedom" or OEF) suffer from the symptoms of Post-traumatic Stress Disorder. PTSD may be the reason behind alarming increases in suicidal behavior among returning veterans in Wisconsin and nation-wide. In addition to traditional treatments, Veterans Administration (VA) Hospitals and other community institutions for veterans now offer CA programs to their patients. Past research from our laboratory and others suggests that CA programs may provide effective relief from anxiety while increasing psychological well-being. However, little research exists on the effects of CA programs for combat veterans with PTSD. The proposed study aims to address this important gap by assessing CA programs such as Sudarshan Kriya Yoga (SKY) and Mindfulness-Based Stress Reduction (MBSR). 150 veterans with PTSD will be randomly assigned to either SKY, MBSR, or the wait-list control (WLC) group. We will assess participants' PTSD symptoms pre-intervention, post-intervention (approximately 10-14 days after initial visit), and 1 month post-treatment (approximately 6 weeks after initial visit). In order to evaluate the programs' effects as comprehensively as possible, we propose a multi-method approach: baseline psychophysiology, autonomic reactivity and recovery, neuropsychological (cognitive) assessments, self-report questionnaires, and functional brain imaging (fMRI). Baseline measures will be collected from a group of 50 combat-exposed veterans without PTSD to assess group differences on these measures prior to treatment.

Group Intervention Description Sudarshan Kriya Yoga: SKY Sudarshan Kriya Yoga SKY incorporates yoga, discussion periods and several types of breathing exercises for relaxation. Initial breathing exercises are calming and focusing. Subsequent breathing exercises are more fully engaging energizing, allowing the practitioner to focus more fully in each moment. All are soothing and present-focused. Participants will be encouraged to learn all the breathing exercises, and to utilize the exercises the ones that seems most appropriate for their needs. 8-day intensive group class (2.5 hours/day) followed by 4 weekly sessions (3 hours/session). Mindfulness-Based Stress Reduction: MBSR Mindfulness-Based Stress Reduction MBSR incorporates yoga, discussion periods, and several types of meditation, all involving attention to the present moment and acceptance of any feelings, sensations or thoughts, allowing the practitioner to calm his or her mind and come back to the present moment. The typical MBSR format will be adapted to match the SKY intervention. This intervention will include an 8-day intensive group class (2.5 hours/day) followed by 4 weekly sessions (3hrs/session).
- Primary Outcome Measures
Name Time Method Change in fMRI brain blood oxygen level-dependent (BOLD) responses Baseline, post-intervention (approx 10-14 days) Brain activation during anticipation of, response to, and recovery from aversive stimuli will be measured at baseline, and the intervention groups will be compared to the wait-list controls following the intervention to assess changes based on the interventions.
Change in PTSD Checklist-Military (PCL-M) scores Baseline, Post-Intervention (approx. 10-14 days), 1 month post-intervention (approx. 6 weeks) Change in Clinician-Administered PTSD Scale (CAPS) scores Baseline, 1 month post-intervention (approx. 6 weeks)
- Secondary Outcome Measures
Name Time Method Changes in self-reported mood, anxiety, and sleep symptoms Baseline, post-intervention (approx. 10-14 days), one month post-intervention (approx. 6 weeks) Changes in neuropsychological functioning Baseline, post-intervention (approx. 10-14 days) Memory, attention, and rapid perceptual processing will be measured using neuropsychological tasks by Cambridge Cognition and/or the NIH toolbox
Changes in peripheral psychophysiological arousal Baseline and post-intervention (approx. 10-14 days) Assessed using multiple measures, including heart rate, heart rate variability, corrugator EMG, and skin conductance.
Quality of sleep Baseline through one month post-intervention (approx. 6 weeks) Sleep quality will be assessed using actigraphy
