A Randomized Controlled Trial of Meditation Compared to Exposure Therapy and Education Control on PTSD in Veterans

The purpose of this study is to compare the effectiveness of the Transcendental Meditation (TM) program to the more standard Cognitive Behavioral Therapy with Prolonged Exposure (CBT-PE) in treating posttraumatic stress disorder (PTSD) in war Veterans over a three month treatment period.

Posttraumatic stress disorder (PTSD) is a common and debilitating anxiety condition that affects up to 20% of war Veterans. PTSD is often a chronic problem for Veterans, affecting reintegration into society, family and marital relationships, sleep, employment stability, substance abuse rates, and risk for depression and suicide, among other areas. Although several effective therapies exist to treat PTSD, research shows that up to half of patients completing these treatments continue to have elevated symptoms indicating the important need for developing additional treatment options.

In the current trial, we propose to test one such new treatment, specifically a meditation practice known as Transcendental Meditation. The Transcendental Meditation (TM) program will be compared to one of the best and most standard of PTSD therapies (Prolonged Exposure therapy), and a educational control group. This study will recruit 210 War Veterans clinically diagnosed with PTSD from the San Diego VA Healthcare System over a 4 year study period.

The intervention period will be 3 months. Study participants will be randomized equally to one of three study groups, either

1. Transcendental Meditation (TM) or
2. Cognitive Behavioral Therapy with Prolonged Exposure (CBT-PE) or
3. Educational control group.

The primary outcome will be scores on the Clinically Administered PTSD Scale (CAPS).

Secondary outcomes will includes scores on PTSD symptoms including depression, anger, mood disturbance and quality of life.

Behavioral or lifestyle factors will also be measured including smoking, alcohol, and non-described drug usage along with compliance with each treatment.

Physiological markers of stress and disease risk will include cortisol, blood pressure, inflammatory markers and body mass.

If successful, these research findings will serve to provide key data on the feasibility and efficacy of the TM program as an alternative therapy for PTSD. The results will serve to inform policy decisions on the study and application of standardized and validated stress reduction programs in veteran populations.
