Mindfulness-based stress reduction and mindfulness-based cognitive therapy: a systematic review of randomized controlled trials

Mindfulness-based stress reduction for comorbid anxiety and depression: case report and clinical considerations

Growing research literature has documented the effectiveness of mindfulness-based interventions for anxiety and depressive disorders. Mindfulness-based stress reduction (MBSR) teaches a series of mindfulness meditation and yoga practices, delivered in a group format during eight weekly sessions plus one full-day session. This case report demonstrates how MBSR was associated with dramatic clinical improvement of an individual with symptoms of panic, generalized anxiety, and depression. Scores on clinical assessment measures suggested clinically severe levels of anxious arousal, generalized anxiety, worry, fear of negative evaluation, and depression at the beginning of the intervention. The scores on all these measures fell well within normal limits 7 weeks later at the end of the intervention, and no remaining symptoms were reported afterward. Increased life satisfaction and quality of life were documented as well. This case illustrates the potential benefit of MBSR as an alternative or adjunctive treatment for comorbid anxiety and depressive disorder symptoms.

Shifting effects in randomised controlled trials of complex interventions: a new kind of performance bias?

OBJECTIVE

Randomised controlled trials (RCTs) aim to provide unbiased estimates of treatment effects. However, the process of implementing trial procedures may have an impact on the performance of complex interventions that rely strongly on the intuition and confidence of therapists. We aimed to examine whether shifting effects over the recruitment period can be observed that might indicate such impact.

METHOD

Three RCTs investigating music therapy vs. standard care were included. The intervention was performed by experienced therapists and based on established methods. We examined outcomes of participants graphically, analysed cumulative effects and tested for differences between first vs. later participants. We tested for potential confounding population shifts through multiple regression models.

RESULTS

Cumulative differences suggested trends over the recruitment period. Effect sizes tended to be less favourable among the first participants than later participants. In one study, effects even changed direction. Age, gender and baseline severity did not account for these shifting effects.

CONCLUSION

Some trials of complex interventions have shifting effects over the recruitment period that cannot be explained by therapist experience or shifting demographics. Replication and further research should aim to find out which interventions and trial designs are most vulnerable to this new kind of performance bias.

Mindfulness-based cognitive therapy in obsessive-compulsive disorder - a qualitative study on patients' experiences

BACKGROUND

Cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) is the first-line treatment for patients with obsessive-compulsive disorder (OCD). However, not all of them achieve remission on a longterm basis. Mindfulness-based cognitive therapy (MBCT) represents a new 8-week group therapy program whose effectiveness has been demonstrated in various mental disorders, but has not yet been applied to patients with OCD. The present pilot study aimed to qualitatively assess the subjective experiences of patients with OCD who participated in MBCT.

METHOD

Semi-structured interviews were conducted with 12 patients suffering from OCD directly after 8 sessions of a weekly MBCT group program. Data were analyzed using a qualitative content analysis.

RESULTS

Participants valued the treatment as helpful in dealing with their OCD and OCD-related problems. Two thirds of the patients reported a decline in OCD symptoms. Benefits included an increased ability to let unpleasant emotions surface and to live more consciously in the present. However, participants also discussed several problems.

CONCLUSION

The data provide preliminary evidence that patients with OCD find aspects of the current MBCT protocol acceptable and beneficial. The authors suggest to further explore MBCT as a complementary treatment strategy for OCD.

Mindfulness-based cognitive therapy for multiple chemical sensitivity: a study protocol for a randomized controlled trial

Background

Multiple chemical sensitivity (MCS) is a condition characterized by recurrent, self-reported symptoms from multiple organ systems, attributable to exposure to a wide range of chemically unrelated substances at low levels. The pathophysiology is unknown, and affected individuals generally favor avoidance of the symptom triggering substances as a coping strategy. The impact of MCS on daily life may thus be severe. An intervention that may effectively reduce the impact of MCS, alleviate the symptoms and the psychological distress associated with the condition is therefore highly needed. In this study we will assess the effects of a mindfulness-based cognitive (MBCT) program on MCS.

Methods/Design

Using a randomized controlled design (RCT), we will compare MBCT with treatment as usual (TAU). The MBCT intervention will include 8 weekly 2.5 hour sessions, and 45 minutes of mindfulness home practice 6 days each week. Participants will be asked to complete questionnaires at baseline, post-treatment, and at 6 and 12 months’ follow-up. Based on sample size estimation, 82 participants will be randomized to either the MBCT intervention or to TAU. The primary outcome will be a measure of the impact of MCS on the participants’ lives. The secondary outcome measures are physical symptoms of psychological distress, perceived stress, illness perceptions, QOL, and work ability. Lastly, we will assess whether any effect of MBCT on the primary effect measure is mediated by level of mindfulness, self-compassion, perceived stress, and rumination.

Discussion

This trial will provide important information on the effects of MBCT on MCS.

Mindfulness-based stress reduction, mindfulness-based cognitive therapy, and Zen meditation for depression, anxiety, pain, and psychological distress

Mindfulness has been described as a practice of learning to focus attention on moment-bymoment experience with an attitude of curiosity, openness, and acceptance. Mindfulness practices have become increasingly popular as complementary therapeutic strategies for a variety of medical and psychiatric conditions. This paper provides an overview of three mindfulness interventions that have demonstrated effectiveness for psychiatric symptoms and/or pain. The goal of this review is to provide a synopsis that practicing clinicians can use as a clinical reference concerning Zen meditation, mindfulness-based stress reduction (MBSR), and mindfulness-based cognitive therapy (MBCT). All three approaches originated from Buddhist spiritual practices, but only Zen is an actual Buddhist tradition. MBSR and MBCT are secular, clinically based methods that employ manuals and standardized techniques. Studies indicate that MBSR and MBCT have broad-spectrum antidepressant and antianxiety effects and decrease general psychological distress. MBCT is strongly recommended as an adjunctive treatment for unipolar depression. The evidence suggests that both MBSR and MBCT have efficacy as adjunctive interventions for anxiety symptoms. MBSR is beneficial for general psychological health and stress management in those with medical and psychiatric illness as well as in healthy individuals. Finally, MBSR and Zen meditation have a role in pain management.

Mindfulness-based cognitive behavior therapy in patients with anxiety disorders: a case series

The present study is aimed at evaluating the effectiveness of a Mindfulness-Based Cognitive Behavior Therapy (MBCBT) for reducing cognitive and somatic anxiety and modifying dysfunctional cognitions in patients with anxiety disorders. A single case design with pre- and post-assessment was adopted. Four patients meeting the specified inclusion and exclusion criteria were recruited for the study. Three patients received a primary diagnosis of generalized anxiety disorder (GAD), while the fourth patient was diagnosed with Panic Disorder. Patients were assessed on the Cognitive and Somatic Anxiety Questionnaire (CSAQ), Penn State Worry Questionnaire (PSWQ), Hamilton's Anxiety Inventory (HAM-A), and Dysfunctional Attitudes Scale. The therapeutic program consisted of education regarding nature of anxiety, training in different versions of mindfulness meditation, cognitive restructuring, and strategies to handle worry, such as, worry postponement, worry exposure, and problem solving. A total of 23 sessions over four to six weeks were conducted for each patient. The findings of the study are discussed in light of the available research, and implications and limitations are highlighted along with suggestions for future research.

The Implementation of Mindfulness-Based Cognitive Therapy: Learning From the UK Health Service Experience

Mindfulness-based cognitive therapy (MBCT) is an effective depression prevention programme for people with a history of recurrent depression. In the UK, the National Institute for Clinical Excellence (NICE) has suggested that MBCT is a priority for implementation. This paper explores the exchange, synthesis and application of evidence and guidance on MBCT between the academic settings generating the evidence and delivering practitioner training and the practice settings where implementation takes place. Fifty-seven participants in a workshop on MBCT implementation in the NHS were asked for their experience of facilitators and obstacles to implementation, and a UK-wide online survey of 103 MBCT teachers and stakeholders was conducted. While MBCT is starting to become available in the NHS, this is rarely part of a strategic, coherent or appropriately resourced approach. A series of structural, political cultural, educational, emotional and physical/technological obstacles and facilitators to implementation were identified. Nearly a decade since NICE first recommended MBCT, only a small number of mental health services in the UK have systematically implemented the guidance. Guiding principles for implementation are set out. We offer an implementation resource to facilitate the transfer of MBCT knowledge into action.

[On the relationship of psychosomatic and mind-body medicine: integrative, complementary or alternative disciplines within an evolutionary approach?]

The text outlines the relation between psychosomatic medicine as an established medical discipline and the emerging concept of mind-body medicine from a historical, clinical and epistemological perspective. Limitations and contributions of both disciplines are discussed and the opportunities within the concept of Integrative Medicine are outlined. Whereas psychosomatic medicine is perceived as a form of transformation through a primarily verbal discoursive relationship, mind-body medicine claims healing through increased traditional techniques of the relaxation response, increased awareness, mindfulness, increasing des-identification and health-promoting lifestyle modification. It becomes clear that mind-body medicine seems to be epistemologically the broader theoretical framework, whereas in a clinical context the combination of both disciplines appears to be complementary and synergistic. The connection between psychosomatic medicine and mind-body medicine can make an important and exemplary contribution to the concept of Integrative Medicine.

Use of complementary and alternative medicine in a large sample of anxiety patients

OBJECTIVE

To examine a large sample of patients with anxiety and the association between types of complementary and alternative treatments that were used, demographic variables, diagnostic categories, and treatment outcomes.

METHOD

Cross-sectional and longitudinal survey during the Coordinated Anxiety Learning and Management (CALM) study that assessed this intervention against the Usual Care in a sample of patients with anxiety recruited from primary care. Interviewer-administered questionnaires via a centralized telephone survey by blinded assessment raters. The interviews were done at baseline, 6, 12, and 18 months of the study. A total of 1004 adults ages 18-75 who met DSM-IV criteria for Generalized Anxiety Disorder (GAD), Panic Disorder, Social Anxiety Disorder, or Post-Traumatic Stress Disorder. We assessed medication/herbal use, the use of any alternative therapies, and combined Complementary and Alternative Medicine (CAM) use.

RESULTS

We found an extensive (43%) use of a variety of CAM treatments that is consistent with previous study results in populations with anxiety. Only a few significant demographic or interventional characteristics of CAM users were found. Users most often had a diagnosis of GAD, were older, more educated, and had two or more chronic medical conditions. CAM users who had a 50% or more drop in anxiety scores over 18 months were less likely to report continued use of alternative therapies.

CONCLUSIONS

The study confirms the importance of awareness of CAM use in this population for possible interference with traditional first-line treatments of these disorders, but also for finding the best integrative use for patients who require multiple treatment modalities.

A brief mindfulness-based cognitive behavioral intervention improves sexual functioning versus wait-list control in women treated for gynecologic cancer

GOAL

The goal of this study was to evaluate a mindfulness-based cognitive behavioral intervention for sexual dysfunction in gynecologic cancer survivors compared to a wait-list control group.

METHODS

Thirty-one survivors of endometrial or cervical cancer (mean age 54.0, range 31-64) who self-reported significant and distressing sexual desire and/or sexual arousal concerns were assigned either to three, 90-minute mindfulness-based cognitive behavior therapy sessions or two months of wait-list control prior to entering the treatment arm. Validated measures of sexual response, sexual distress, and mood, as well as laboratory-evoked physiological and subjective sexual arousal were assessed at pre-, one month post-, and 6-months following treatment.

RESULTS

There were no significant effects of the wait-list condition on any measure. Treatment led to significant improvements in all domains of sexual response, and a trend towards significance for reducing sexual distress. Perception of genital arousal during an erotic film was also significantly increased following the intervention despite no change in physiologically-measured sexual arousal.

CONCLUSIONS

A brief mindfulness-based intervention was effective for improving sexual functioning. Geographic restrictions permitted only a select sample of survivors to participate, thus, the generalizability of the findings is limited. Future studies should aim to develop online modalities for treatment administration to overcome this limitation.

The Continuing Evolution of Biopsychosocial Interventions for Chronic Pain

In the last several decades, great strides have been made in the treatment of persistent painful conditions. The scope of treatment has shifted from purely biomedical, including approaches built upon cognitive, behavioral, and social psychological principles. This article reports and discusses several key paradigm shifts that fueled this revolutionary change in the management of chronic pain. The progressive development of theoretical metamodels and treatment conceptualizations is presented. Cognitive behavioral therapy (CBT) is the most widely accepted biopsychosocial treatment for chronic pain and is founded upon a rich theoretical tradition. The CBT rationale, and empirical evidence to support its efficacy, is presented. The emergence and promise of mindfulness-based and acceptance-based interventions is also discussed. The article concludes with the assertion that future treatment outcome research should focus on understanding the treatment-specific and common factors associated with efficacy.
