Long-Term Effects of the Transcendental Meditation and Mindfulness Programs

Most studies on Mindfulness Based Stress Reduction (MBSR) are over an 8 week period, and there are only a few long-term studies of a year or more on MBSR or other mindfulness programs. (1-6) By contrast, there are several long-term studies on the Transcendental Meditation technique.

Transcendental Meditation


Decreased Mortality (7): 18.8 years maximum, 7.6 years mean follow up; RCT, N = 202.

  • -23% decreased all-cause mortality
  • -30% decreased cardiovascular mortality
  • -49% cancer mortality

No Studies on Mortality.

Decreased Recidivism Among Former Prison Inmates: 15 years, 12.2 years average followup (8). RCS, N = 248.

  • 43.5% reduction in recidivism controlling for 22 demographics
  • permanent rehabilitation
  • less severe re-offending
  • synergistic effect; TM + therapy was greater that the effects of TM and therapy added together, indicating that TM enhances the effects of therapy.

No Studies on Recidivism.

Decreased Medical Expenditures: 14 years, pre and post intervention, 6 year post intervention (9). RCS, N = 2,836.

  • -13.8% annual reduction in physicians costs

No Studies on Medical Expenditures.

Decreased Medical Care Utilization: 11 years (10). RCS, N = 693 TM, 600,000 norms.

  • -74% hospital days/1000
  • -55% outpatient visits/1000
  • -63% total medical expenditures

Note: Similar results were found comparing TM subjects to a matched control group of 4,148 people over 4 years.

Medical Utilization: 1 year (11).UPP, N = 73 total, 47 chronic care, 36 Spanish.

  • total group, non-significant decreases in total visits, chronic care visits, or the number of acute visits
  • chronic care subgroup;-24% chronic care visits
  • Spanish subgroup; -22% total visits, -34% chronic care visits

Increased Personality Development: 10 Years (12) PCS, N = 136.

  • increased ego development
  • increased moral reasoning
  • increased intimacy motivation

No Studies on Personality Development

Decreased Coronary Heart Disease Events: 9 years maximum, 5.4 years mean followup (13, 14). RCT, N = 201.

  • -47% all-cause mortality, myocardial infarction, strokes
  • -24% cardiovascular mortality, revascularizations, cardiovascular hospitalization
  • -4.9 mm Hg systolic blood pressure
  • decreased anger expression

No Studies on Coronary Heart Disease Events.

Decreased Medical Expenditures Among High Cost People: 6 years, Five years followup(15). RCS, N = 284.

  • -28% cumulative reduction in physician costs

No Studies on Medical Expenditures.

Decreased Medical Care Utilization: 5 years (16). RCS, N = 694 to 2119 for TM, 1468 mean; 22,440 total for five control groups, 600,000 norms.

  • -63% inpatient medical
  • -71% inpatient surgical
  • -59% outpatient medical
  • -56% outpatient surgical

See above, reference 11.

RCT = Randomized Controlled Trial: subjects were randomly allocated to receive the TM or Control treatment in a prospective study. RCS = Retrospective Cohort Study: subjects who learned TM were compared on outcomes over time with similar control subjects who did not learn TM, using archival data. PCT = Prospective Controlled Trial: in a prospective study, subjects who had learned TM were compared on standard tests over time with similar control subjects who did not learn TM. UPP = uncontrolled Pre-Post experiment: subjects were measured before and after treatment, no control group.
