Brief Summary

Hyperarousal is a key symptom of PTSD. Even after receiving trauma-focused therapy, PTSD patients may continue to suffer from hyperarousal. Our main objectives are to measure hyperarousal in VA outpatients with PTSD related to combat experience in the last 10 years and to test the efficacy of physiological relaxation training in reducing this hyperarousal. Measurements will be both physiological, using 24 hour ambulatory monitoring of skin conductance, heart rate, and physical activity during waking and sleeping, and psychological, using self-reports and clinician interviews. Specific aims include initially evaluating 100 or more PTSD patients for the severity of their hyperarousal symptoms. Of these, 50 with at least moderate hyperarousal who either have participated in a trauma-focused therapy or have declined to participate in such a therapy will be recruited for a therapy trial. Volunteers will be randomized to treatment consisting of 5 sessions of individual physiological relaxation training with biofeedback over a 4-week period or to a 2-month waiting period after which they also may receive this therapy. Physiological evaluations of the patients' ability to relax will be measured at three times -before treatment, immediately after treatment, and 6 months after treatment. Clinical evaluations by interviews and questionnaires on measures of symptoms and disability will be measured at four times - before treatment, immediately after treatment, 1 month after treatment, and 6 months after treatment. The waiting-list group and a nonanxious control group will be tested psychophysiologically twice at the same interval as the patients before and immediately after treatment. A control group will allow us to calibrate our measures in the setting in which they are being applied. We hypothesize that this therapy will relieve both self-reported and objective, physiological symptoms of hyperarousal. Relevance to health and the VA mission: Many of our clients at the VA Palo Alto Mental Health Outpatient Services for PTSD are veterans of Iraq, who need help with hyperarousal symptoms. This study will fill in gaps in our knowledge about the physiology of these symptoms and about the efficacy of relaxation therapies. Non-pharmacological treatments like the ones that we propose may relieve patients' hyperarousal to an extent that they are less tempted to turn to alcohol or sedative drugs.

Outcome Measures

Primary Outcomes (1)

  • Change Scores for Criteria D Items on the CAPS Structured Clinical Interview

    Change in total score for all criterion D items on the Clinician-Administered PTSD Scale for DSM-IV, from baseline to post-treatment. Total Criterion D subscore = sum of all frequency (0-4) and intensity (0-4) ratings of 5 PTSD hyperarousal symptoms. Range: 0 to 40, with higher scores indicating more severe (frequent and/or intense) symptoms. Change score calculated as: CAPS D score time 2 - CAPS D score time 1. Greater negative change scores indicate greater reduction in symptom severity (aka symptom improvement).
