This study evaluated the effectiveness of a stress reduction
intervention (SRI) offered to employees at one worksite where 80 were
employed. 41 Volunteers (aged 21-65) participated in Transcendental
Meditation (TM), and 18 (aged 19-46) in Progressive Muscle Relaxation
(PMR). Two groups did not attend the SRI. These were 11 non-volunteers
for the SRI (aged 25-58) who served as on-site controls, while 16
outside attendees (aged 27-44) of a personal productivity workshop
served as off-site controls. All subjects completed a standardised
stress symptoms questionnaire (SCL-90-R) before and after the SRI.
On-site subjects also had blood pressure, heart and breath rates
measured by a trained nurse and completed a company climate
questionnaire--before and after the SRI. Structured interviews were
conducted at three-year follow-up. The hypothesis that test groups would
show significant reductions in psychological stress symptoms was
supported at 6 weeks.
