Mindfulness: A proposed operational definition.

Clinical Psychology Science and Practice January 1, 2004 Scott R. Bishop, Mark A. Lau, Shauna L. Shapiro et al. 6,266 citations

Mindfulness has attracted considerable interest as a way to reduce cognitive vulnerability to stress and emotional distress, but it has not been defined operationally. Recent consensus meetings produced a two-component model of mindfulness, specifying each component in terms of specific behaviors, experiential manifestations, and psychological processes. The paper addresses temporal stability and situational specificity, speculates on the conceptual and operational distinctiveness of mindfulness, and discusses implications for instrument development and measurement.

A Randomized, Wait-List Controlled Clinical Trial: The Effect of a Mindfulness Meditation-Based Stress Reduction Program on Mood and Symptoms of Stress in Cancer Outpatients

Psychosomatic Medicine September 1, 2000 Michael Speca, Linda E. Carlson, Eileen Goodey et al. 1,091 citations

A mindfulness meditation-based stress reduction program reduced mood disturbance and stress symptoms in cancer outpatients. In a randomized trial, 90 patients with various cancer types and stages completed a 7-week program of weekly 1.5-hour meditation groups plus home practice. Compared to a wait-list control group, those in the program showed significantly lower total mood disturbance, including less depression, anxiety, anger, and confusion, and more vigor. They also reported fewer overall stress symptoms, particularly cardiopulmonary and gastrointestinal symptoms, emotional irritability, and cognitive disorganization. Total mood disturbance decreased by 65%, and stress symptoms by 31%.

Mindfulness-Based Stress Reduction in Relation to Quality of Life, Mood, Symptoms of Stress, and Immune Parameters in Breast and Prostate Cancer Outpatients

Psychosomatic Medicine July 1, 2003 Linda E. Carlson, Michael Speca, Kamala D. Patel et al. 773 citations

An 8-week mindfulness-based stress reduction program for early-stage breast and prostate cancer patients was associated with improved quality of life, reduced stress symptoms, and better sleep quality. Although overall immune cell counts did not change, T cell production of IL-4 increased and IFN-gamma decreased, while NK cell production of IL-10 decreased, suggesting a shift in immune profile away from one linked to depressive symptoms. This is the first study to show changes in cancer-related cytokine production with MBSR participation.

Exploring self‐compassion and empathy in the context of mindfulness‐based stress reduction (MBSR)

Stress and Health March 15, 2010 Kathryn A. Birnie, Michael Speca, Linda E. Carlson 599 citations

A community sample participated in an 8-week Mindfulness-Based Stress Reduction (MBSR) programme. After the programme, participants showed significant reductions in stress symptoms and mood disturbance, along with increases in mindfulness, spirituality, and self-compassion. For empathy, perspective taking increased significantly and personal distress decreased significantly, but empathic concern did not change. Changes in self-compassion were linked to changes in mindfulness. Self-compassion and certain aspects of empathy were strongly associated with psychological well-being. The findings suggest MBSR can enhance self-compassion and specific empathy components.

A qualitative study of self‐perceived effects of mindfulness‐based stress reduction (MBSR) in a psychosocial oncology setting

Stress and Health November 28, 2006 Michael J. Mackenzie, Linda E. Carlson, Marleny Munoz et al. 178 citations

Nine cancer patients who completed an 8-week Mindfulness-based Stress Reduction (MBSR) program and continued attending weekly drop-in sessions described five themes from adding meditation to their lives: opening to change, self-control, shared experience, personal growth, and spirituality. These themes were used to develop theory about how MBSR creates change for cancer patients, which may help refine programs to better support patients during diagnosis, treatment, and recovery.

Increased Mindfulness Is Related to Improved Stress and Mood Following Participation in a Mindfulness-Based Stress Reduction Program in Individuals With Cancer

Integrative Cancer Therapies April 13, 2012 Sheila N. Garland, Rie Tamagawa, Sarah C. Todd et al. 91 citations

Participation in an 8-week mindfulness-based stress reduction (MBSR) program led to significant increases in mindfulness among 268 individuals with cancer. These increases accompanied a 55% reduction in mood disturbance and a 29% reduction in stress symptoms. Gains in mindfulness accounted for 21% of the mood improvement and 14% of the stress reduction. The two most important mindfulness skills for better psychological functioning were being aware of the present moment and refraining from judging inner experience.

Mindfulness and Tai Chi for Cancer Health (MATCH) Study: Primary Outcomes of a Preference-Based Multisite Randomized Comparative Effectiveness Trial.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology June 12, 2025 Linda E. Carlson, Jennifer M Jones, Devesh Oberoi et al. 4 citations

A large pragmatic trial compared two mind-body interventions—Mindfulness-Based Cancer Recovery (MBCR) and Tai Chi/Qigong (TCQ)—for distressed cancer survivors. Participants could choose their preferred program or be randomly assigned; all were also randomized to immediate intervention or a waitlist. Among 587 participants (average age 60.7, 75% female, mostly breast cancer survivors), both MBCR and TCQ groups improved more than waitlist controls on total mood disturbance, with small to medium effects. Choosing a program or being randomly assigned did not affect outcomes. The largest improvements were in tension, anger, and vigor for MBCR, and anger, depression, and vigor for TCQ.
