A randomized, controlled trial of meditation for work stress, anxiety and depressed mood in full-time workers

Objective: To assess the effect of meditation on work stress, anxiety and mood in full-time workers. Methods. 178 adult workers participated in an 8-week, 3-arm randomized controlled trial comparing a "mental silence" approach to meditation (n=59) to a "relaxation" active control (n=56) and a wait-list control (n=63). Participants were assessed before and after using Psychological Strain Questionnaire (PSQ), a subscale of the larger Occupational Stress Inventory (OSI), the State component of the State/Trait Anxiety Inventory for Adults (STAI), and the depression-dejection (DD) subscale of the Profile of Mood States (POMS). Results. There was a significant improvement for the meditation group compared to both the relaxation control and the wait-list groups the PSQ (P=.026), and DD (P=.019). Conclusions. Mental silence-orientated meditation, in this case Sahaja Yoga meditation, is a safe and effective strategy for dealing with work stress and depressive feelings. The findings suggest that thought reduction or mental silence may have specific effects relevant to work stress and hence occupational health.
