Mindfulness-based stress reduction (MBSR) is a consciousness discipline that is grounded in eastern philosophy and traditions such as yoga and Buddhism, focusing on awareness of the present moment. It aims to teach people to deal more effectively with experience through awareness of feelings, thoughts, and bodily sensations. Participants learn to engage in mindfulness practices such as body scan, simple yoga exercises, and meditation. MBSR has been studied in patients with cancer for its effect on symptoms of anxiety, cognitive impairment, fatigue, sleep-wake disturbances, and depression. It has also been studied in caregivers of patients with cancer for its effect on caregiver strain and burden.

To evaluate current evidence regarding the effect of mindfulness-based therapy (MBT) on symptoms of anxiety and depression in patients with cancer
Multiple phases of care
Among nonrandomized studies, overall effect size for anxiety was 0.60 (Hedges’s g, p < 0.001) and 0.42 (p < 0.001) for depression. Among randomized controlled trials, effect size for anxiety was 0.37 and 0.44 (p < 0.001) for depression. Most studies used the Profile of Mood States scale or the State-Trait Anxiety Inventory. The range of Jadad quality scores was 0–4, with only six studies having scores greater than 2. This score indicates low quality. Heterogeneity among studies was moderate.
Findings demonstrate a low to moderately significant effect of MBT in reducing anxiety and symptoms of depression among patients with cancer. Heterogeneity among studies suggests that findings be viewed with caution.
MBT may benefit patients with cancer by reducing anxiety and symptoms of depression. The use of MBT appears to be feasible in cancer care. The low quality of studies in this analysis points to the need for well-designed research on the effects of MBT.

PHASE OF CARE: Active antitumor treatment
The meta-analysis supported the efficacy of mindfulness-based therapies in the improvement of anxiety and depression levels for people with cancer. The authors note that previous meta-analysis of MBSR studies included only 2 of 9 studies that were RCTs. All seven studies included in this analysis were RCTs. MBSR and mindfulness-based art therapy were the most frequently used mindfulness therapies (5 of 7), and all studies reported anxiety and depression scores. Subgroup analysis of the data further supported the effectiveness of mindfulness-based intervention in relieving anxiety and depression across cancer type and stage.
This meta-analysis supports the effectiveness of mindfulness-based interventions for management of cancer-related anxiety and depression.

To report the six-month follow-up effects of a mindfulness stress reduction training program on perceived stress, depression, anxiety, post-traumatic stress symptoms, positive states of mind coping, self-efficacy, and mindfulness among patients treated for cancer
Patients with a previous cancer diagnosis were recruited and randomized into an intervention group or a waiting list control group. Questionnaires were sent to participants directly by mail after randomization at three and six months. The waiting list participants were scheduled to participate in the intervention program after six months. The intervention involved eight-week, two-hour, weekly sessions of mindfulness training. The sessions consisted of experiential and group exercises. The training was an adaptation of the Jon Kabat-Zinn program of mindfulness-based stress reduction (MBSR) from the Stress Reduction and Relaxation Clinic at the Massachusetts Medical center in Shrewsbury. For details of the program, the authors refer to a previous publication.
Randomized, controlled intervention and wait-list groups; random selection of participants was done consecutively using a random sequence of numbers indicating group assignment
Compared to participants in the control group, the intervention group showed a larger increase in mindfulness at the six-month follow-up. There were no differences in any other outcomes between the intervention and control groups. 60% of the participants reported regular meditation practice during the intervention period. Continued meditation practice was associated with a significant reduction in post-traumatic stress symptoms of avoidance. Change in psychological distress, positive states of mind, and coping self-efficacy did not show any significant differences between the control and intervention group. There were trends in a greater reduction of perceived stress. There was a significant change in the intervention group reporting increases in mindfulness. Postintervention, 38% of the participants in the intervention group continued to meditate regularly. Those in the intervention group who continued to mediate regularly after the intervention had a significant reduction in post-traumatic avoidance symptoms at the six-month follow-up (t = 2.5, p < .5). No other significant intervention effects on psychological outcomes were found.
The study indicates the need to better understand the mechanism behind the effects of MBSR and the potential modification of mindfulness interventions to promote a sustained benefit over time. Future studies should examine the potential of additional intervention tools to encourage postintervention meditation practice. The short-term positive effects of mindfulness training and the particular time when mindfulness intervention might have the most positive effects should be further studied.
The lack of sustained, positive effects from mindfulness training suggests that booster sessions or tools for increasing postintervention adherence to mindfulness practice would be beneficial. Assisting patients in integrating mindfulness training into everyday life would benefit patients as the increased dispositional level of mindfulness moderates the influence of stress on both depression and perceived health.

To determine the feasibility and acceptability of mindfulness-based stress reduction to manage the symptoms of fatigue, anxiety, and depression in women with metastatic breast cancer
An eight-week mindfulness-based (Kabat Zinn) stress reduction course was taught by a trained, experienced instructor. The sessions in weeks 1 and 8 were two and a half hours, and week 2–7 sessions were two hours. Week 6 included a day of mindfulness of four and a half hours. Home practice with CDs 30 minutes a day was recommended. Sessions were done in a group setting.
Mixed method design using qualitative and quantitative data with repeated measures
Qualitative data consisted of interviews one to two weeks prior to the course and four months after the course. Quantitative data consisted of four questionnaires delivered at five time points: the Brief Fatigue Inventory (BFI), the Hospital Anxiety and Depression Scale (HADS), the EuroQol Quality of Life-5 Dimensions, and the Toronto Mindfulness Scale (TMS) at baseline and at weeks 4, 8, 15, and 24. Quantitative data consisted of one questionnaire at two time points: the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30) at baseline and at week 24.
A group mindfulness-based stress reduction intervention appeared feasible for patients with stable advanced cancer. However, the intervention as used here was time intensive. This type of intervention may be helpful in dealing with some symptoms in patients with advanced disease.
There is an opportunity to study mindfulness-based stress reduction in patients with metastatic breast cancer and other patients with advanced disease. This study showed that this may be feasible; however, recruitment was difficult, and patients identified barriers related to severity of illness, time commitment, and travel to attend sessions.

To explore the impact of mindfulness-based cancer stress management (MBCSM) programs on depression, anxiety, and stress in individuals affected by cancer with a secondary aim to evaluate the impact of MBCSM on quality of life and spiritual well-being
Four MBCSM programs were run for clients experiencing psychological distress related to cancer diagnoses. Each group consisted of 9–13 participants. The program consisted of eight, two-hour, weekly sessions in which mindfulness exercises were provided by an experienced counselor trained in mindfulness-based cognitive therapy. Participants also were asked to complete 40 minutes of meditation per day with the aid of notes, practice CDs, and home worksheets. A three-hour follow-up session was offered six weeks after the completion of the program. The program was modified to incorporate elements of the mindfulness-based stress reduction program developed by Jon Kabat-Zinn in 1990. Session 4 specifically included education about the psychoneuroimmunology of stress and an exploration of the cancer survivorship experience within the context of anxiety, depression, and stress.
Single-group, quasiexperimental study of participants directly and indirectly affected by cancer
Exploratory analysis indicated that there were no significant differences between baseline scores across sociodemographic groups. A series of Friedman tests indicated that there were significant differences in the levels of global psychological distress over time. Scores were significantly higher at baseline than postintervention for levels of global distress, anxiety, and depression. Global quality of life and spiritual well-being improved significantly over time. Emotional well-being and functional well-being were significantly higher postintervention than at the baseline assessment, which was maintained from baseline to follow-up (p = .001 and p = .001, respectively). Physical well-being improved from baseline to postintervention, which was determined to be significant at follow-up (p = .012). Mindfulness scores changed significantly over time. The level of mindfulness was significantly lower at baseline than postintervention, which was maintained through follow-up (p = .001).
Overall, the results of this study were positive with significant improvements in participants' levels of global distress, anxiety, and depression from baseline to postintervention. Improvements in psychological distress were sustained up to three months postintervention. This supports preliminary research on the effectiveness of mindfulness-based therapy in the treatment of cancer-related psychological distress.
Mindfulness training should be considered for patients with cancer to improve their levels of distress, anxiety, and depression. Mindfulness programs require trained personnel, and the program should involve an intervention over time with opportunity for follow-up over time.

To examine the effects of a mindfulness-based stress-reduction therapy (MBSRT) on stress and mood disturbances and to examine the relationship of improved mindfulness and mood changes.
Hospital staff referred patients to the study or patients self-referred to the study. MBSRT consisted of eight weekly sessions and a six-hour silent retreat held after the sixth session. Classes taught participants about the mind-body connection, principles of mindfulness, and yoga practice. Patients were encouraged to share experiences to generate support from group members. All were given CDs with guided meditation exercises, and all received a program manual. Patients were encouraged to practice meditation and mindful movement at least 45 minutes per day. Patients who did not attend at least five sessions were excluded from the analysis.
Patients were undergoing the transition phase after active treatment.
The study used a pre-/posttest design.
The findings supported the use of MBSRT approaches for managing the symptoms of anxiety, depression, and fatigue.
The findings suggested that a stress-reduction intervention involving group support, yoga, and mindfulness may help patients manage the symptoms of anxiety, depression, and fatigue. The various study limitations prevented firm conclusions from being drawn.

To compare effects of a mindfulness-based intervention to those of a psychoeducational telephone consultation on quality of life, depression, fatigue, and anxiety.
The study was begun as a randomized, controlled trial and patients were allocated at random to either the mindfulness-based or psychoeducational groups. Because of patient complaints about group assignment, in the second half of the study, patients were allocated to the group of their choice. The mindfulness intervention was based on mindfulness-based stress reduction concepts and activities and was provided in 2.5-hour group sessions weekly for eight weeks. They also had homework assignments, two 2.5-hour booster sessions at the end of 1 and 2 months during a three-month follow-up phase, and an all-day retreat. At baseline, individuals were interviewed to establish individual goals and, at the end of the program, were interviewed regarding goal attainment, maintenance of acquired skills, and evaluation of personal experience. The comparison group received 15-30 minutes of psychoeducational consultations by telephone twice a month for eight weeks. During the follow-up period, they had additional phone calls at the end of months 1 and 2. Study measures were obtained two weeks before and after the initial intervention and three months postintervention. Consultation with intervention teachers was used to evaluate treatment fidelity.
Quality of life and depression improved immediately after the intervention (p < 0.02) At the three-month follow-up, significant differences were noted between groups, with improved quality of life in the mindfulness group (p = 0.04) and lower depressive symptoms and anxiety in the psychoed group (p = 0.04). There was no significant effect of either intervention on fatigue. There were no differences in outcomes based on whether the patient was randomly assigned or chose the preferred intervention.
Findings suggest that a mindfulness-based intervention may have positive benefits for overall quality of life and depressive symptoms in the short term, but this study did not show a long-term impact on depression or anxiety. No effect was seen for fatigue.
Findings suggest that a group mindfulness-based program for HCT survivors is feasible, although the overall attrition and poor attendance at follow-up sessions suggests it is difficult to maintain involvement in the longer term. Additional study incorporating Web-based and telephonic follow-up boosters might be more practical for patients to attend. Although there were some immediate effects for depressive symptoms, these were not long lasting. Additional research is needed to explore long-term benefits and most effective methods for delivery of this type of intervention.

Effectiveness of mindfulness-based stress reduction in mood, breast- and endocrine-related quality of life, and well-being in stage 0 to III breast cancer: a randomized, controlled trial. Journal of Clinical Oncology, 30, 1335–1342.
The intervention consisted of an eight-week MBSR program closely following the Kabat-Zinn method. The intervention involved 2- to 2.25-hour classes and a 6-hour retreat. Home practice was recommended for 45 minutes, six to seven days per week. Outcomes were measured at baseline, weeks 8 to 12, and weeks 12 to 14. A wait-list control group received usual care.
The study used a randomized, controlled trial design.
MBSR significantly improved mood and reduced confusion.
Although further study is needed to measure MBSR and its impact on depression and anxiety, in this sample, home-based practice was feasible and improved mood. In practice and education, nurses can promote components of MBSR, such as breathing, yoga, relaxation, meditation, seeking support resources, and gentle stretching.

To assess the efficacy of mindfulness-based therapy on pain and distress in women treated for breast cancer
After completing baseline questionnaires, patients were randomized to the intervention or waitlist control group. The intervention was adapted from a standard intervention manual to the use of a shorter two-hour session, shorter meditation exercises, more gentle yoga exercises, and the elimination of all day sessions. The intervention was delivered in groups during eight consecutive weeks. All sessions were facilitated by a trained mindfulness instructor. Study measurements were conducted after the intervention and at three and six months after completion.
PHASE OF CARE: Transition phase after active treatment
Randomized, controlled trial with waitlist control
Pain intensity and neuropathic pain declined over time in the intervention group compared to the control group (p = 0.036). No differences in anxiety or depression over time were reported between groups. The average number of sessions attended was five, and the average amount of time spent on homework was 24 minutes per day. A direct correlation between number of sessions attended (p = 0.01) and time spent on practice (p = 0.01) was reported. The dropout rate was 22% across both study groups; only four dropouts were in the control group.
Participation in the mindfulness-based intervention was associated with a reported reduction in pain intensity; however, a large percentage of those allocated to the intervention dropped out of the study or were lost to follow-up, suggesting that the intervention as provided may not be practical to many patients.
Mindfulness-based group therapy may be helpful in the management of long-term pain with breast cancer but was not shown to have an affect on anxiety or depression over time. The strength of findings in this study is limited because of study limitations.
Johns, S.A., Brown, L.F., Beck-Coon, K., Talib, T.L., Monahan, P.O., Giesler, R.B., . . . Kroenke, K. (2016). Randomized controlled pilot trial of mindfulness-based stress reduction compared to psychoeducational support for persistently fatigued breast and colorectal cancer survivors. Supportive Care in Cancer, 24, 4085–4096.
To compare mindfulness-based stress reduction (MBSR) with psychoeducation/support groups (PES) as interventions to treat cancer-related fatigue (CFR) and associated symptoms of anxiety, depression, vitality, sleep disturbances, and pain. An active treatment control group (PES) was used to determine the effect size of MBSR in reducing CRF.
Breast cancer survivors (BCSs) and colorectal cancer survivors (CRCSs) were blinded and randomized into the MBSR group or the PES intervention. The primary outcome was CRF interference, and secondary outcomes of CRF were severity, vitality, anxiety, depression, sleep disturbances, and pain at baseline (T1), postintervention (T2) and at six months postintervention (T3). Both arms of the study included a structured curriculum that lasted two hours weekly for eight weeks. As the MBSR cohort had required exercises and practice assigned between classes, the PES arm was also given between-session practice and supplemental readings related to class topics. Treatment fidelity to each of the interventions was maintained by use of standardized manuals for each (MBSR and PES), audio recordings of the sessions with review by investigators using checklists created to evaluate the interventions. The MBSR intervention was adapted from standard approaches to eliminate the use of a retreat, the addition of psychoeducation, a brief body scan at bedtime, and shorter home practices. The PES program incorporated group discussions.
PHASE OF CARE: Late effects and survivorship
Single-blind, two-armed, randomized clinical pilot trail
The primary outcome of CRF interference did not significantly differ between MBSR and PES, although a trend (insignificant) toward MBSR was observed at T2 (d = –0.46, p = 0.073). Secondary outcome of vitality demonstrated moderate and significant effect size in the MBSR arm compared to the PES arm (d = 0.53, p = 0.003) at T2; however, the between group difference did not last through the T3 measurement. The MBSR maintained improvement in vitality, whereas vitality improved in the PES group. In addition, at T2, the MBSR participants were significantly more likely to report CRF global improvement (58.8 versus 34.3%, respectively, X2 (1) = 4.176, p = 0.041). Both groups continued to report similar global improvements in CRF at T3 (MBSR = 45.5 versus PES = 54.3%, X2 (1) = 0.53, p = 0.467). Pain was the only between group secondary outcome in which MBSR demonstrated moderate and significant improvement at T3 compared to PES (d = –0.50, p = 0.014).
Within group effects: Both MBSR and PES participants demonstrated moderate to large effects and significant improvements on all fatigue outcomes at T2 and T3 compared to T1. Participants in both groups also reported moderate to large effects and significant improvements at T2 and T3 from baseline in depression (p < 0.001), anxiety (p < 0.001), and sleep disturbance (p < 0.001).
Although the aim of this study was to rigorously test MBSR as an intervention for CRF in preparation for a phase-III randomized, controlled trial, the study supported the strength of PES as an intervention as well.
Although MBSR has been shown an effective intervention for numerous cancer-related symptoms, including CRF, a structured PES intervention was also clearly effective in helping survivors manage fatigue and other symptoms. However, given the more immediate effect of MBSR for participants, MBSR may provide results sooner. Both interventions are efficacious and therefore provide cancer survivors a choice in interventions effective in reducing CRF and its interference in daily life through anxiety, depression, and sleep disturbance.

To compare the prevalence and severity of symptoms and symptom clusters in patients with breast cancer who participated in a mindfulness-based stress reduction (MBSR) program to the symptoms and symptom clusters in patients who received usual care.
Women who expressed interest in participating in the study were randomly assigned to MBSR or usual care. The MBSR program lasted six weeks and included educational material, meditation practice in weekly group settings and homework, group discussion on barriers to meditation, application of mindfulness in daily life, and group support interactions. Meditation training consisted of sitting and walking meditation, body scan, and gentle Hatha yoga. Researchers obtained study measures at baseline and within two weeks of program conclusion. Hierarchical-cluster analysis was used to identify symptom clusters. Researchers compared each group's symptom clusters and individual symptoms to those of the other group.
This was a randomized, controlled trial.
MD Anderson Symptom Inventory
Severity of symptoms declined in both groups from baseline to the end of the study. Fatigue and drowsiness declined more in the MBSR group (p = 0.05). Interference scores for mood and relationships also declined more in the MBSR group (p ≤ 0.05). Analysis of changes in symptom clusters showed no differences between groups. Clusters identified were gastrointestinal (nausea, vomiting, anorexia, shortness of breath, dry mouth, numbness), cognitive or psychological (distress, sadness, pain, remembering), and fatigue (fatigue, disturbed sleep, drowsiness). Cluster scores declined in both groups.
Findings suggested that MBSR interventions may benefit women with breast cancer who are managing fatigue or mood.
Findings suggested that MBSR may be helpful, to some patients with breast cancer, as a means of combating fatigue and mood changes. Study limitations limited the strength of these findings.

Mindfulness based stress reduction (MBSR [BC]) in breast cancer: Evaluating fear of recurrence (FOR) as a mediator of psychological and physical symptoms in a randomized control trial (RCT). Journal of Behavioral Medicine, 37, 185–195.
To investigate the mechanisms of action of elements of mindfulness-based stress reduction (MBSR) that lead to specific clinical improvements, specifically to postulate and examine how changes in fear of recurrence as a result of participation in MBSR program may mediate a range of positive changes in psychological and physical symptoms and quality of life
At orientation, subjects were consented and randomized, and they completed baseline assessments. The assessments were completed again at two and six weeks following the MBSR program or control period. The program was adapted from the 1990 Jon Kabat-Zinn program. Subjects who were randomized to the MBSR group (n = 40) attended six, weekly, two-hour MBSR sessions with a trained psychologist. Participants learned four meditative practices, sitting meditation, walking meditation, body scan, and yoga, while integrating mindful attention to self-regulate and manage stressful symptoms. Participant materials included a training manual and audio tapes for home practice. Subjects completed a diary daily. Home meditation was advised for 15–45 minutes daily. The usual care (UC) group was offered the MBSR program after the six-week study period.
This was a randomized, controlled trial. Subjects were randomly assigned in a one-to-one ratio to either the MBSR or UC group. Randomization was stratified in an unblocked manner. Study personnel were blinded initially.
From baseline to six-weeks, the MBSR group experience more favorable changes than the UC group for several potential mediators including fear of recurrence concerns (2.8 versus .2, p = .007); fear of recurrence problems (11.4 versus .2, p = .02); depression (7.2 versus 4, p = .04); physical functioning (3.8 versus .5, p = .01) and energy (8.8 versus 5, p = .07). After removing direct effects of MBSR on outcomes of interest, the strongest and most consistent evidence for mediating effects (how MBSR works) was for change in fear of recurrence problems and change in physical functioning. The results indicate that MBSR is associated with reduced fear of recurrence and improved physical functioning which in turn are associated with reduced perceived stress and state and trait anxiety. The women in the UC group who experienced reduced fear of recurrence and improved physical functioning by mechanisms other than MBSR also experienced significantly reduced perceived stress and anxiety. Both groups experienced reduced anxiety and depression over time. There were no significant differences in anxiety between groups. Postintervention, the MBSR group had significantly higher depression scores (p = .04).
The fear of recurrence is highly prevalent in breast cancer survivors and is associated with considerable psychological distress. The results of this study may indicate that one of the mechanisms for how MBSR (BC) works is through the cognitive process of self-regulation of fear of recurrence to improve stress, anxiety, and physical functioning. The fear of recurrence influence by MBSR (BC) appeared to be reliable and clinically relevant. The findings did not demonstrate a direct effect on anxiety or depression scores.
The findings of this study show a clustering of multiple symptoms among breast cancer survivors. Interventions to simultaneously address multiple symptoms should be studied. MBSR is supported as being beneficial in reducing fear of recurrence and improving physical functioning. Training programs and awareness for nurses and staff members should be supported in cancer centers and survivorship programs.

To evaluate changes in cerebral blood associated with a mindfulness-based art therapy program (employing functional magnetic resonance imaging) and correlate such changes to stress and anxiety in women with breast cancer
The Mindfulness-based Art Therapy (MBAT) intervention arm consisted of the basic mindfulness-based stress reduction (MBSR) curriculum paired with expressive art tasks. The design of MBAT was intended to provide opportunities for self-expression, facilitate coping strategies, and improve self-regulation. The MBSR aspect of the MBAT intervention provided standardized tools to help participants observe, assess, and negotiate their objective and subjective experiences of the illness process. A variety of mindfulness meditation techniques were taught during the eight-week program, including body scan, awareness of breathing, awareness of emotions, and mindful yoga, walking, eating, and listening.
A randomized, qualitative study design was used.
Response to the program was evaluated using the Symptom Checklist-90 Revised (SCL-90-R) as a way to rate behavior. The SCL-90-R was obtained pre- and post-MBAT and within one week of the pre- and post-functional MRI scans. The SCL-90-R is a 90-item inventory that assesses nine symptom dimensions and a summary score, the Global Severity Index. Functional MRI scans were also obtained as a way to correlate scores on the SCL-90-R with results of the functional MRI.
Overall, the study showed significant differences in cerebral blood flow in the insula, caudate, and amygdala in patients who underwent an eight-week MBAT program. Given the improvements in anxiety levels (lower scores on the SCL-90-R), these findings suggest that at the level of these brain structures, the MBAT intervention may help to mediate emotional responses in women with breast cancer.
Women who used MBAT techniques had lower scores on the anxiety scale, and also a difference in cerebral blood flow in the insula, caudate, and amygdala regions shown through functional MRI studies. These areas have known correlations with stress and anxiety.
Brief guided imagery or simple meditation techniques could be employed by nurses to relieve patients’ stress and anxiety. Guiding patients toward reading about meditation and guided imagery and encouraging them to try these techniques on their own may also be useful.

To assess the impact of an eight-week mindfulness-based cognitive therapy program on individuals experiencing distress as a consequence of cancer
Participants included people with a history of cancer and those the study defined as carers. Participants were people who called the Cancer Council South Australia Helpline. They were assessed for anxiety and depression before and after a course of mindfulness-based cognitive therapy (MBCT). The MBCT program consisted of eight weekly two-hour sessions facilitated by an experienced counselor. The program sessions included these topics: stepping out of automatic pilot; dealing with barriers; mindfulness of one’s breath; staying present; acceptance; holding, allowing, letting be; thoughts are not facts; how to best take care of oneself; and using learned skills to control future mood. An optional three-hour follow-up session occurred six weeks after program completion, to reinforce mindfulness principles.
Prospective, one-group, pre/post-test design
Poor study design and small sample prevent drawing a valid conclustion about the effect of the intervention.
MBCT may be an effective intervention for cancer survivors and carers who are willing to make a time commitment for sessions and homework. Further research is warranted.

Mindfulness significantly reduces self-reported levels of anxiety and depression: Results of a randomised controlled trial among 336 Danish women treated for stage I–III breast cancer. European Journal of Cancer 49,1365–1373.
To test, in a randomized controlled study, the effect of a structured eight-week group mindfulness-based stress-reduction program on anxiety and depression among women with breast cancer
The mindfulness-based stress-reduction program consisted of eight weekly two-hour group sessions. The program included guided meditation, yoga and psychoeducational advice on stress and stress reactions, and group dialog about the integration of mindfulness practice into daily life. Three experienced clinical psychologists provided the program. The control group received usual care. Data were collected before randomization and at 6 and 12 months after the intervention.
A randomized controlled trial design was used.
The mindfulness-based stress-reduction program was effective in reducing anxiety and depression over time in the patients studied. The intervention was most effective for those who had higher levels of anxiety and depression at baseline.
The intervention appears to be effective. It does, however, require that the facilitator receive special training, which is an extra cost, and the intervention may be difficult to implement in the practice setting. The study does not address whether the effectiveness of the intervention varies with phase of care. As with other types of intervention, the mindfulness-based stress-reduction program appeared to be most effective for patients who had higher levels of anxiety and depression at the beginning of treatment, suggesting that appropriate patient selection for such an intervention can be beneficial. This study was limited by the lack of attentional control; providing attention alone may positively affect the anxiety and depression of patients with cancer.
