Transcendental Meditation technique (tm) shows a positive effect on reducing trait anxiety for people with high anxiety, says study. Trait anxiety is a measure of how anxious a person usually is, as opposed to state anxiety, which refers to how anxious we are at the moment. A meta-analysis is an objective means to draw conclusions from all the research in a field.
This meta-analysis covered 16 randomized-controlled trials, the gold standard in medical research, and included 1295 subjects from various walks of life, age groups, and life situations.
TM was compared with various control groups, including treatment-as-usual, individual and group psychotherapy, and various relaxation techniques.
Studies on high stress groups, such as veterans suffering from PTSD and prison inmates, showed dramatic reductions in anxiety from TM practice, whereas studies of groups with only moderately elevated anxiety levels, such as normal adults and college students, showed more modest changes.
A chart shows that studies of individuals with anxiety levels in the 90th percentile (higher than 90 percent of the rest of the adult population) showed dramatic reductions in anxiety down to the 57th percentile from TM practice.
This is just a little higher than the average anxiety level, which is the 50th percentile. Study groups that started in the 60th percentile, a little above average, showed more modest reductions, to the 48th percentile, a little below average.
The new study has been published in the Journal of Alternative and Complementary Medicine.
