The purpose of this study was to examine the effects of a MBSR program on physiological and psychological outcomes among early-stage breast cancer survivors. A quasi-experimental, pre-and posttest control group design was selected. The intervention group received the MBSR intervention. The control group received no MBSR intervention. ANOVA and ANCOVA were used to analyze data. The intervention group demonstrated statistically significant improvement in physiological and psychological outcomes including reduced blood pressure, heart rate, and respiratory rate and increased mindfulness state at the level of p = .05 to p = .001. The effects of MBSR on reducing stress in this sample were statistically significant on the physiological outcome (morning cortisol) at the measurement after the intervention completion, but this effect was not sustained at 1-month follow-up. MBSR showed a trend toward improving psychological outcomes by reducing mood disturbance in this sample.
Purpose/Objectives: To describe the construct of mindfulness meditation and systematically review instruments measuring the psychological impact of mindfulness-based stress reduction (MBSR) on health among patients with cancer.Data Sources: PubMed, CINAHL®, PsycINFO®, ISI Web of Knowledge®, EBSCO, and published literature (1987-2006).
Data Synthesis: 13 psychological instruments used in seven studies (2000-2005) to measure effects of MBSR on health in patients with cancer were reviewed. Most studies used a one-group pre- and post-test design. The post-MBSR outcomes for each instrument varied, suggesting different yet promising relationships. For some instruments, data were insufficient to conclude sufficiently whether any were strong or appropriate to use in future intervention studies.
Conclusions: To enhance knowledge of MBSR, more intervention research studies of MBSR in patients with cancer and reexamination of specific instruments are needed.
Implications for Nursing: Based on the review, instruments can measure MBSR effects and found MBSR to be a potentially beneficial oncology nursing intervention.
