Future directions in meditation research: Recommendations for expanding the field of contemplative science.

The science of meditation has grown tremendously in the last two decades. Most studies have focused on evaluating the clinical effectiveness of mindfulness-based interventions, neural and other physiological correlates of meditation, and individual cognitive and emotional aspects of meditation. Far less research has been conducted on more challenging domains to measure, such as group and relational, transpersonal and mystical, and difficult aspects of meditation; anomalous or extraordinary phenomena related to meditation; and post-conventional stages of development associated with meditation. However, these components of meditation may be crucial to people's psychological and spiritual development, could represent important mediators and/or mechanisms by which meditation confers benefits, and could themselves be important outcomes of meditation practices. In addition, since large numbers of novices are being introduced to meditation, it is helpful to investigate experiences they may encounter that are not well understood. Over the last four years, a task force of meditation researchers and teachers met regularly to develop recommendations for expanding the current meditation research field to include these important yet often neglected topics. These meetings led to a cross-sectional online survey to investigate the prevalence of a wide range of experiences in 1120 meditators. Results show that the majority of respondents report having had many of these anomalous and extraordinary experiences. While some of the topics are potentially controversial, they can be subjected to rigorous scientific investigation. These arenas represent largely uncharted scientific terrain and provide excellent opportunities for both new and experienced researchers. We provide suggestions for future directions, with accompanying online materials to encourage such research.

Critical analysis of the efficacy of meditation therapies for acute and subacute phase treatment of depressive disorders: a systematic review.

BACKGROUND: Recently, the application of meditative practices to the treatment of depressive disorders has met with increasing clinical and scientific interest, owing to a lower side-effect burden, potential reduction of polypharmacy, and theoretical considerations that such interventions may target some of the cognitive roots of depression. OBJECTIVE: We aimed to determine the state of the evidence supporting this application. METHODS: Randomized controlled trials of techniques meeting the Agency for Healthcare Research and Quality definition of meditation, for participants having clinically diagnosed depressive disorders, not currently in remission, were selected. Meditation therapies were separated into praxis (i.e., how they were applied) components, and trial outcomes were reviewed. RESULTS: 18 studies meeting the inclusion criteria were identified, encompassing 7 distinct techniques and 1173 patients. Mindfulness-Based Cognitive Therapy comprised the largest proportion of studies. Studies including patients having acute major depressive episodes (n = 10 studies), and those with residual subacute clinical symptoms despite initial treatment (n = 8), demonstrated moderate to large reductions in depression symptoms within the group, and relative to control groups. There was significant heterogeneity of techniques and trial designs. CONCLUSIONS: A substantial body of evidence indicates that meditation therapies may have salutary effects on patients having clinical depressive disorders during the acute and subacute phases of treatment. Owing to methodologic deficiencies and trial heterogeneity, large-scale, randomized controlled trials with well-described comparator interventions and measures of expectation are needed to clarify the role of meditation in the depression treatment armamentarium.

Lifestyle and mental health.

Mental health professionals have significantly underestimated the importance of lifestyle factors (a) as contributors to and treatments for multiple psychopathologies, (b) for fostering individual and social well-being, and (c) for preserving and optimizing cognitive function. Consequently, therapeutic lifestyle changes (TLCs) are underutilized despite considerable evidence of their effectiveness in both clinical and normal populations. TLCs are sometimes as effective as either psychotherapy or pharmacotherapy and can offer significant therapeutic advantages. Important TLCs include exercise, nutrition and diet, time in nature, relationships, recreation, relaxation and stress management, religious or spiritual involvement, and service to others. This article reviews research on their effects and effectiveness; the principles, advantages, and challenges involved in implementing them; and the forces (economic, institutional, and professional) hindering their use. Where possible, therapeutic recommendations are distilled into easily communicable principles, because such ease of communication strongly influences whether therapists recommend and patients adopt interventions. Finally, the article explores the many implications of contemporary lifestyles and TLCs for individuals, society, and health professionals. In the 21st century, therapeutic lifestyles may need to be a central focus of mental, medical, and public health.

The meeting of meditative disciplines and Western psychology: a mutually enriching dialogue.

Meditation is now one of the most enduring, widespread, and researched of all psychotherapeutic methods. However, to date the meeting of the meditative disciplines and Western psychology has been marred by significant misunderstandings and by an assimilative integration in which much of the richness and uniqueness of meditation and its psychologies and philosophies have been overlooked. Also overlooked have been their major implications for an understanding of such central psychological issues as cognition and attention, mental training and development, health and pathology, and psychological capacities and potentials. Investigating meditative traditions with greater cultural and conceptual sensitivity opens the possibility of a mutual enrichment of both the meditative traditions and Western psychology, with far-reaching benefits for both.

Emotional effects of sertraline: novel findings revealed by meditation.

Use of selective serotonin reuptake inhibitors continues to increase, as does concern about previously unrecognized, subtle side effects and questions about whether these drugs produce effects on healthy subjects. The authors report novel emotional effects identified by an experienced, psychologically healthy meditator who is a psychiatrist and researcher. On a meditation retreat, the subject identified a specific profile of emotional changes related to sertraline use. In particular, cognitive abilities and the emotions of fear and anger seemed unaffected. However, the emotions of sadness, happiness, rapture, and love were dramatically reduced in intensity and duration.

Subjective effects of antidepressants: a pilot study of the varieties of antidepressant-induced experiences in meditators.

The use of antidepressants continues to increase, yet relatively little is known about their precise subjective effects, and there is growing concern about subtle psychological side effects. One novel investigative approach to these problems may be to use introspectively trained subjects such as meditators. Experienced meditators recently taking antidepressants rated antidepressant effects on multiple dimensions of experience and reported significant emotional, motivational, and cognitive effects and benefits. This study suggests that a) meditators may benefit both clinically and meditatively from antidepressants, b) meditators may provide significant novel information on antidepressant effects, c) meditators may prove valuable for phenomenological investigations of psychopathology, drug effects, and therapies, d) meditation may prove a helpful maintenance therapy for depression, and e) enhanced equanimity may contribute to the broad therapeutic efficacy of antidepressants.
