Zhang, J., Zhou, Y., Feng, Z., Fan, Y., Zeng, G., & Wei, L. (2017). Randomized controlled trial of mindfulness-based stress reduction (MBSR) on posttraumatic growth of Chinese breast cancer survivors. Psychology, Health and Medicine, 22, 94–109.
To evaluate acceptability and effects of MBSR on perceived stress and anxiety
Women with breast cancer were randomly assigned to MBSR or usual care groups. The usual care group could receive the MBSR intervention after the study was completed. MBSR was provided in two-hour weekly sessions for eight weeks. Study measures were obtained at baseline, after eight weeks, and three months later. The sessions were provided in groups of 4 to 6 patients. The MBSR intervention did not include a retreat.
PHASE OF CARE: Transition phase after active treatment
Single blind RCT
Those in the MBSR group showed lower perceived stress scores at eight weeks and three months (p = 0.00); scores also declined in everyone over time (p = 0.00). STAI cores declined more in the MBSR group (p = 0.00), with an effect size of 0.21. State anxiety also declined in everyone over time, with an effect size of 0.39 (p = 0.00).
MBSR had a positive effect to reduce anxiety in this study.
This study showed that a mindfulness-based stress reduction intervention was associated with reducing anxiety levels in women with breast cancer. This is a low-risk intervention that can be helpful for individuals with cancer who have anxiety.
