In a study of 59 veterans and healthcare workers, the reliability of a self-monitoring method used to track the frequency of a spiritually oriented stress reduction technique was assessed. During a 5-week program of silently repeating a mantram (a spiritual word or phrase) to lower stress and anger and improve spiritual well-being, portable wrist-worn counters were used to track daily mantram practice sessions. All outcomes significantly improved in the hypothesized direction. Mantram practice tracked by the counters was highly correlated (r = .84) with retrospective self-reports, indicating that such counters may be a reliable self-monitoring tool and could be used to measure a variety of other behavioral health quality indicators.
