The objectives of the study were (1) to evaluate self-reported stress levels and daily spiritual experiences in academic health care employees before, immediately after, and 1 year after enrolling in a mindfulness-based stress reduction (MBSR) course; and (2) to evaluate the correlation between a potential measure of pulse rate variability and self-reported stress levels.
Fifty-nine (59) participants in the MBSR course offered to employees at the University of Texas Medical Branch in Galveston (UTMB) comprised the intervention group, and 94 health care providers in the neonatal nurseries comprised the control group.
MBSR is an 8-week course that introduces mindfulness meditation practices. No intervention was offered to the control group. All participants were employees (or relatives of employees) at UTMB.
All MBSR participants completed Cohen's Perceived Stress Scale, the SCL-90, the SF-36 Measure of Health and Well-Being, the Daily Spiritual Experiences Scale, and a 5-minute measure of pulse rate coherence. This testing was done before and after the MBSR course and 1 year later. Ninety-four (94) neonatal health care providers completed the same series of questionnaires and pulse rate variability (PRV) measures, with 49 of the 94 completing the questionnaires 2 months and 1 year later.
MBSR participants improved on all measures except the physical component score of the SF-36 upon completion of the MBSR course, and these results were maintained at the 1-year follow-up. The control group did not significantly change on any of the measures. PRV as measured by the Heart Math system did not correlate with any of the self-report questionnaires.
MBSR effectively reduces self-report measures of stress and increases daily spiritual experiences in employees in an academic health care setting, and these effects are stable for at least 1 year. Using a simple measure of PRV was not a clinically reliable biologic measure of stress.
本研究的目的是：（1）评估参加正念减压（MBSR）课程的学术医疗保健员工在课程开始前、结束后和 1 年后的自我报告压力水平和日常精神体验；（2）评估脉搏率变异性（PRV）的潜在测量指标与自我报告压力水平之间的相关性。
59 名参加 MBSR 课程的受试者来自德克萨斯大学加尔维斯顿医学分部（UTMB）的员工，他们组成干预组，94 名新生儿病房的医疗保健提供者组成对照组。
MBSR 是一项为期 8 周的课程，介绍正念冥想练习。对照组未接受任何干预。所有参与者均为 UTMB 的员工（或员工亲属）。
所有 MBSR 参与者都完成了 Cohen 的压力感知量表、SCL-90、SF-36 健康和幸福感量表、日常精神体验量表以及 5 分钟的脉搏率相干性测量。这些测试在 MBSR 课程前后和 1 年后进行。94 名新生儿医疗保健提供者完成了相同的问卷和脉搏率变异性（PRV）测量系列，其中 49 名在 2 个月和 1 年后完成了问卷。
MBSR 参与者在完成 MBSR 课程后，除了 SF-36 的生理成分评分外，在所有测量指标上均有所改善，这些结果在 1 年的随访中得到了维持。对照组在任何测量指标上均无显著变化。由 Heart Math 系统测量的 PRV 与任何自我报告问卷均无相关性。
MBSR 可有效降低学术医疗保健环境中员工的自我报告压力水平并增加日常精神体验，这些效果至少可稳定 1 年。使用 PRV 的简单测量方法不是压力的可靠生物学测量指标。
