The Seattle Vipassana Study
In 1997, the North Rehabilitation Facility (NRF) in Seattle partnered with researchers to study the effects of Vipassana meditation on incarcerated individuals.
Study Design
- Participants: Pre-trial detainees and sentenced inmates volunteered.
- Control: Compared against inmates who did not take the course.
- Researchers: Sarah Bowen, G. Alan Marlatt, and University of Washington colleagues.
Results
- Behavioral: Participants committed fewer disciplinary infractions.
- Psychological: Reductions in stress, hostility, and craving.
- Social: Facility staff observed greater calm, cooperation, and respect.
Long-Term Impact
Follow-ups showed lasting reductions in substance use and relapse rates.
This pioneering effort inspired further Vipassana programs in correctional settings across North America.
