Recent studies claiming that Transcendental Meditation is effective in treating PTSD, and that it provides other benefits, treat TM as a “black box.” As with many similar past studies, researchers fail to consider that this method of meditation instruction contains several hours of other information, which creates a context of expectation of life improvement, a structure or habit which will improve life, and an authority who provides the assurance that TM will unfailingly produce those changes. These inadequacies in the design of these studies would be obvious, if all aspects of instruction in the TM program that have never been opened for examination by the TM teaching organization were properly studied and controlled for by independent researchers.
Another research study, this time on using TM as a method of treating PTSD, has just been published in the Journal of Traumatic Stress. The study, “A Pilot Randomized Controlled Trial of Transcendental Meditation as Treatment for Posttraumatic Stress Disorder in Veterans,” purports to show that “Veterans with PTSD who practiced the Transcendental Meditation technique showed significant reductions in PTSD symptom severity.” A widely circulated press release issued by Maharishi International University announced this study, headlined with the “Transcendental Meditation effective in reducing PTSD, sleep problems, depression symptoms” claim. It includes the same sort of ubiquitous bar chart that’s been seen in TM promotional efforts since at least the mid-1970’s.
It should be noted that while the data analysis performed in this study showed significant positive changes with respect to PTSD, insomnia, depression and anxiety, there were no significant changes on the measures of anger and quality of life, the last being one of TM’s traditional selling points. More notable is the way in which this study, as with many others performed with the participation of the Maharishi International University (MIU) research faculty, relies on a vague if not inappropriately inaccurate description of Transcendental Meditation, as if it were solely a method practiced inside the mind and contained no other significant aspects, doctrine or belief that might in some way affect behavior which would then produce these results, among some people, for some limited period of time.
