Adolescence is a time of change that can be both exciting and stressful. In this review, we focus on the central role that disturbed sleep and daytime sleepiness occupies in interactions involving substance abuse and negative health, social, and emotional outcomes. As a means of improving sleep and lowering risk for recidivism of substance abuse, we developed and implemented a six-session group treatment to treat sleep disturbances in adolescents who have received treatment for substance abuse. The components of the treatment are stimulus control instructions, use of bright light to regularize sleep, sleep hygiene education, cognitive therapy, and Mindfulness-Based Stress Reduction. Preliminary evidence indicates that participants who completed four or more sessions in the treatment program showed improved sleep and that improving sleep may lead to a reduction in substance abuse problems at the 12-month follow-up.

OBJECTIVE: The underlying changes in biological processes that are associated with reported changes in mental and physical health in response to meditation have not been systematically explored. We performed a randomized, controlled study on the effects on brain and immune function of a well-known and widely used 8-week clinical training program in mindfulness meditation applied in a work environment with healthy employees. METHODS: We measured brain electrical activity before and immediately after, and then 4 months after an 8-week training program in mindfulness meditation. Twenty-five subjects were tested in the meditation group. A wait-list control group (N = 16) was tested at the same points in time as the meditators. At the end of the 8-week period, subjects in both groups were vaccinated with influenza vaccine. RESULTS: We report for the first time significant increases in left-sided anterior activation, a pattern previously associated with positive affect, in the meditators compared with the nonmeditators. We also found significant increases in antibody titers to influenza vaccine among subjects in the meditation compared with those in the wait-list control group. Finally, the magnitude of increase in left-sided activation predicted the magnitude of antibody titer rise to the vaccine. CONCLUSIONS: These findings demonstrate that a short program in mindfulness meditation produces demonstrable effects on brain and immune function. These findings suggest that meditation may change brain and immune function in positive ways and underscore the need for additional research.

While much attention has been devoted to examining the beneficial effects of Mindfulness-Based Stress Reduction programs on patients' ability to cope with various chronic medical conditions, most studies have relied on self-report measures of improvement. Given that these measures may not accurately reflect physiological conditions, there is a need for an objective marker of improvement in research evaluating the beneficial effects of stress management programs. Cortisol is the major stress hormone in the human organism and as such is a promising candidate measure in the study of the effects of Mindfulness-Based Stress Reduction programs. In conjunction with other biological measures, the use of cortisol levels as a physiological marker of stress may be useful to validate self-reported benefits attributed to this program. In the current manuscript, we review the available literature on the role of cortisol as a physiological marker for improvement with regards to mindfulness practice, and make recommendations for future study designs.

Demands faced by health care professionals include heavy caseloads, limited control over the work environment, long hours, as well as organizational structures and systems in transition. Such conditions have been directly linked to increased stress and symptoms of burnout, which in turn, have adverse consequences for clinicians and the quality of care that is provided to patients. Consequently, there exists an impetus for the development of curriculum aimed at fostering wellness and the necessary self-care skills for clinicians. This review will examine the potential benefits of mindfulness-based stress reduction (MBSR) programs aimed at enhancing well-being and coping with stress in this population. Empirical evidence indicates that participation in MBSR yields benefits for clinicians in the domains of physical and mental health. Conceptual and methodological limitations of the existing studies and suggestions for future research are discussed.

<p>Recent research has demonstrated that higher levels of mindfulness are associated with greater psychological and physical health. However, the majority of this research has been conducted with adults; research is only beginning to examine the effects of mindfulness among adolescents. Further, research into adolescent mindfulness has typically conceptualized mindfulness as a unidimensional phenomenon and has not yet examined multidimensional models of mindfulness that have emerged in the adult literature. Further, the mechanisms through which mindfulness influences these outcomes are presently unclear. The present study examined the effects of three facets of mindfulness among adolescents. Seventy-eight adolescents (61% female, 94% Caucasian, M age = 16) completed a measure of dispositional mindfulness at baseline. Participants then completed measures of daily stress, dysphoric affect, and state rumination over a 7-day period. Multilevel modeling analyses revealed that facets of mindfulness (i.e., nonreactivity and nonjudgment) were associated with lower levels of dysphoric mood. Mindfulness interacted with daily stress to predict later dysphoria; less mindful individuals were particularly vulnerable to the negative effects of stress. Finally, analyses demonstrated that the effect of the Mindfulness × Stress Moderation was significantly mediated by increases in daily rumination. These findings support the importance of mindfulness among adolescents and help to elucidate the mechanisms through which mindfulness influences psychological health.</p>

Mindfulness meditation practices (MMPs) are a subgroup of meditation practices which are receiving growing attention. The present paper reviews current evidence about the effects of MMPs on objective measures of cognitive functions. Five databases were searched. Twenty three studies providing measures of attention, memory, executive functions and further miscellaneous measures of cognition were included. Fifteen were controlled or randomized controlled studies and 8 were case–control studies. Overall, reviewed studies suggested that early phases of mindfulness training, which are more concerned with the development of focused attention, could be associated with significant improvements in selective and executive attention whereas the following phases, which are characterized by an open monitoring of internal and external stimuli, could be mainly associated with improved unfocused sustained attention abilities. Additionally, MMPs could enhance working memory capacity and some executive functions. However, many of the included studies show methodological limitations and negative results have been reported as well, plausibly reflecting differences in study design, study duration and patients' populations. Accordingly, even though findings here reviewed provided preliminary evidence suggesting that MMPs could enhance cognitive functions, available evidence should be considered with caution and further high quality studies investigating more standardized mindfulness meditation programs are needed.

Studies on the effects of mindfulness interventions on mental health and behavioral problems in children show promising results, but are primarily conducted with selected samples of children. The few studies investigating school-based interventions used self-selected samples, provided training outside of the classroom, and did not report longer-term effects. The immediate and longer-term effects of a class-based mindfulness intervention for elementary school children were investigated as a primary prevention program (MindfulKids) to reduce stress and stress-related mental health and behavioral problems. Children (8–12 years) from three elementary schools participated. Classes were randomized to an immediate-intervention group (N = 95) or a waitlist-control group (N = 104), which received the intervention after a waitlist period. Twelve 30-min sessions were delivered in 6 weeks. At baseline, pretest, posttest, and follow-up, variables indicative of stress and metal well-being were assessed with children, variables indicative of mental health problems were assessed with parents, and teachers reported on class climate. Multilevel analysis revealed that there were no significant changes from baseline to pretest. Some primary prevention effects on stress and well-being were found directly after training and some became more apparent at follow-up. Effects on mental health problems also became apparent at follow-up. MindfulKids seems to have a primary preventive effect on stress, well-being, and behavior in schoolchildren, as reported by children and parents. Exploratory analysis revealed that children who ruminate more are affected differently by the intervention than children who ruminate less. It is concluded that mindfulness training can be incorporated in elementary schools at the class level, letting all children benefit from the intervention.

The inability to cope successfully with the enormous stress of medical education may lead to a cascade of consequences at both a personal and professional level. The present study examined the short-term effects of an 8-week meditation-based stress reduction intervention on premedical and medical students using a well-controlled statistical design. Findings indicate that participation in the intervention can effectively (1) reduce self-reported state and trait anxiety, (2) reduce reports of overall psychological distress including depression, (3) increase scores on overall empathy levels, and (4) increase scores on a measure of spiritual experiences assessed at termination of intervention. These results (5) replicated in the wait-list control group, (6) held across different experiments, and (7) were observed during the exam period. Future research should address potential long-term effects of mindfulness training for medical and premedical students.

<p>S. L. Shapiro and colleagues (2006) have described a testable theory of the mechanisms of mindfulness and how it affects positive change. They describe a model in which mindfulness training leads to a fundamental change in relationship to experience (reperceiving), which leads to changes in self-regulation, values clarification, cognitive and behavioral flexibility, and exposure. These four variables, in turn, result in salutogenic outcomes. Analyses of responses from participants in a mindfulness-based stress-reduction program did not support the mediating effect of changes in reperceiving on the relationship of mindfulness with those four variables. However, when mindfulness and reperceiving scores were combined, partial support was found for the mediating effect of the four variables on measures of psychological distress. Issues arising in attempts to test the proposed theory are discussed, including the description of the model variables and the challenges to their assessment. © 2009 Wiley Periodicals, Inc.

<p>OBJECTIVES: Given the demands of caring for chronically ill children, it is not surprising that caregivers often experience high levels of chronic stress. A Mindfulness-Based Stress Reduction (MBSR) program may offer relief to these caregivers by providing tools for self-care and heath promotion that otherwise may be lacking. METHODS: MBSR classes were offered without restriction to parents of children attending various clinics at a large urban children's medical centre. Caregivers completed the Profile of Mood States (POMS) and Symptoms of Stress Inventory (SOSI) both before and after program participation. RESULTS: Forty-four caregivers participated in one of seven group MBSR sessions that were offered between August 2001 and February 2004. Most were mothers of children with special needs and various chronic conditions, who had been diagnosed an average of 7 years previous. Prior to the intervention, caregivers reported very high levels of stress and mood disturbance. These decreased substantially over the 8-week program, with an overall reduction in stress symptoms of 32% (p &lt; .001), and in total mood disturbance of 56% (p &lt; .001). CONCLUSIONS: This brief MBSR program for caregivers of chronically ill children was successful in significantly decreasing substantial stress symptoms and mood disturbance. Further studies would benefit from using more rigorous methodology and applying the program to other groups of chronically stressed caregivers.</p>

Research in mindfulness-based methods with young people is just emerging in the practice/research literature. While much of this literature describes promising approaches that combine mindfulness with cognitive-behavioral therapy, this paper describes an innovative research-based group program that teaches young people in need mindfulness-based methods using arts-based methods. The paper presents qualitative research findings that illustrate how young people in need (children and youth involved with child protection and/or mental health systems) can benefit from a creative approach to mindfulness that can teach them emotional regulation, social and coping skills, and that can improve aspects of their self-awareness, self-esteem, and resilience.

<p>The mindfulness-based stress reduction (MBSR) program was designed to be long enough for participants to grasp the principles of self-regulation through mindfulness and develop skill and autonomy in mindfulness practice. It traditionally consists of 26 hours of session time including eight classes of 2-1/2 hours and an all-day class. The circumstances of some groups exclude them from participating in this standard form and a number of trials have evaluated programs with abbreviated class time. If lower program time demands can lead to similar outcomes in psychological functioning, it would support their utility in these settings and might lead to greater participation. However, the effect of variation in class hours on outcomes has not been systematically studied. To obtain preliminary information related to this question we examined effect sizes for psychological outcome variables in published studies of MBSR, some of which had adapted the standard number of class hours. The correlation between mean effect size and number of in-class hours was nonsignificant for both clinical and nonclinical samples and suggests that adaptations that include less class time may be worthwhile for populations for whom reduction of psychological distress is an important goal and for whom longer time commitment may be a barrier to their ability or willingness to participate. However, the standard MBSR format has accrued the most empirical support for its efficacy and session time may be important to the development of other kinds of program outcomes. The result points to the importance of empirical studies systematically examining this question. © 2009 Wiley Periodicals, Inc. J Clin Psychol 65: 1–12, 2009.</p>

There is increasing evidence for the utility of mindfulness training as a clinical intervention. Most of this research has examined secular-based mindfulness instruction. The current study examined the effects of a 10-day Buddhist mindfulness meditation course on the psychological symptoms of 53 participants. A repeated-measures analysis of variance indicated reductions in overall psychological distress from the pre-course baseline to a 3-month follow-up. Correlation analyses indicated that the reported reduction in psychological distress was not influenced by social desirability bias and that the effect was not dependent on daily meditation between course completion and follow-up. Issues regarding modality of mindfulness training (secular versus Buddhist) are discussed.

<p>Mindfulness-based approaches are increasingly employed as interventions for treating a variety of psychological, psychiatric and physical problems. Such approaches include ancient Buddhist mindfulness meditations such as Vipassana and Zen meditations, modern group-based standardized meditations, such as mindfulness-based stress reduction and mindfulness-based cognitive therapy, and further psychological interventions, such as dialectical behavioral therapy and acceptance and commitment therapy. We review commonalities and differences of these interventions regarding philosophical background, main techniques, aims, outcomes, neurobiology and psychological mechanisms. In sum, the currently applied mindfulness-based interventions show large differences in the way mindfulness is conceptualized and practiced. The decision to consider such practices as unitary or as distinct phenomena will probably influence the direction of future research. © 2011 Wiley Periodicals, Inc. J Clin Psychol 67:1-21, 2011.</p>

Interest in applications of mindfulness-based approaches with adults has grown rapidly in recent times, and there is an expanding research base that suggests these are efficacious approaches to promoting psychological health and well-being. Interest has spread to applications of mindfulness-based approaches with children and adolescents, yet the research is still in its infancy. I aim to provide a preliminary review of the current research base of mindfulness-based approaches with children and adolescents, focusing on MBSR/MBCT models, which place the regular practice of mindfulness meditation at the core of the intervention. Overall, the current research base provides support for the feasibility of mindfulness-based interventions with children and adolescents, however there is no generalized empirical evidence of the efficacy of these interventions. For the field to advance, I suggest that research needs to shift away from feasibility studies towards large, well-designed studies with robust methodologies, and adopt standardized formats for interventions, allowing for replication and comparison studies, to develop a firm research evidence base.

<p>Recovered recurrently depressed patients were randomized to treatment as usual (TAU) or TAU plus mindfulness-based cognitive therapy (MBCT). Replicating previous findings, MBCT reduced relapse from 78% to 36% in 55 patients with 3 or more previous episodes; but in 18 patients with only 2 (recent) episodes corresponding figures were 20% and 50%. MBCT was most effective in preventing relapses not preceded by life events. Relapses were more often associated with significant life events in the 2-episode group. This group also reported less childhood adversity and later first depression onset than the 3-or-more-episode group, suggesting that these groups represented distinct populations. MBCT is an effective and efficient way to prevent relapse/recurrence in recovered depressed patients with 3 or more previous episodes.</p>

<p>Baer's review (2003; this issue) suggests that mindf ulness-based interventions are clinically efficacious, but that better designed studies are now needed to substantiate the field and place it on a firm foundation for future growth. Her review, coupled with other lines of evidence, suggests that interest in incorporating mindfulness into clinical interventions in medicine and psychology is growing. It is thus important that professionals coming to this field understand some of the unique factors associated with the delivery of mindfulness-based interventions and the potential conceptual and practical pitfalls of not recognizing the features of this broadly unfamiliar landscape. This commentary highlights and contextualizes (1) what exactly mindfulness is, (2) where it came from, (3) how it came to be introduced into medicine and health care, (4) issues of cross-cultural sensitivity and understanding in the study of meditative practices stemming from other cultures and in applications of them in novel settings, (5) why it is important for people who are teaching mind-fulness to practice themselves, (6) results from 3 recent studies from the Center for Mindfulness in Medicine, Health Care, and Society not reviewed by Baer but which raise a number of key questions about clinical applicability, study design, and mechanism of action, and (7) current opportunities for professional training and development in mindfulness and its clinical applications.</p>

<p>This study was designed to test the hypothesis that mindfulness involves sustained attention, attention switching, inhibition of elaborative processing and non-directed attention. Healthy adults were tested before and after random assignment to an 8-week Mindfulness-Based Stress Reduction (MBSR) course (n = 39) or a wait-list control (n = 33). Testing included measures of sustained attention, attention switching, Stroop interference (as a measure of inhibition of elaborative processing), detection of objects in consistent or inconsistent scenes (as a measure of non-directed attention), as well as self-report measures of emotional well-being and mindfulness. Participation in the MBSR course was associated with significantly greater improvements in emotional well-being and mindfulness, but no improvements in attentional control relative to the control group. However, improvements in mindfulness after MBSR were correlated with improvements in object detection. We discuss the implications of these results as they relate to the role of attention in mindfulness. Copyright © 2007 John Wiley &amp; Sons, Ltd.</p>

Objective: Mindfulness-based stress reduction (MBSR) is a structured group program that employs mindfulness meditation to alleviate suffering associated with physical, psychosomatic and psychiatric disorders. The program, nonreligious and nonesoteric, is based upon a systematic procedure to develop enhanced awareness of moment-to-moment experience of perceptible mental processes. The approach assumes that greater awareness will provide more veridical perception, reduce negative affect and improve vitality and coping. In the last two decades, a number of research reports appeared that seem to support many of these claims. We performed a comprehensive review and meta-analysis of published and unpublished studies of health-related studies related to MBSR. Methods: Sixty-four empirical studies were found, but only 20 reports met criteria of acceptable quality or relevance to be included in the meta-analysis. Reports were excluded due to (I) insufficient information about interventions, (2) poor quantitative health evaluation, (3) inadequate statistical analysis, (4) mindfulness not being the central component of intervention, or (5) the setting of intervention or sample composition deviating too widely from the health-related MBSR program. Acceptable studies covered a wide spectrum of clinical populations (e.g., pain, cancer, heart disease, depression, and anxiety), as well as stressed nonclinical groups. Both controlled and observational investigations were included. Standardized measures of physical and mental well-being constituted the dependent variables of the analysis. Results: Overall, both controlled and uncontrolled studies showed similar effect sizes of approximately 0.5 (P <.0001) with homogeneity of distribution. Conclusion: Although derived from a relatively small number of studies, these results suggest that MBSR may help a broad range of individuals to cope with their clinical and nonclinical problems.

OBJECTIVE: To determine whether completing a mindfulness-based stress reduction (MBSR) program would affect the general health, health-related quality of life, sleep quality, and family harmony of Spanish- and English-speaking medical patients at an inner-city health center. MATERIALS AND METHODS: An intervention group of 68 patients (48 Spanish-speaking and 20 English-speaking) completed the SF-36 Health Survey and two additional questions about sleep quality and family harmony before and after completing the 8-week MBSR program. A comparison group of 18 Spanish-speaking patients who received no intervention completed the same questionnaire at the same intervals. RESULTS: Sixty-six percent of the total intervention group completed the 8-week MBSR program. There was significant comorbidity of medical and mental health diagnoses among the intervention and comparison groups, with no differences in the mean number of diagnoses of the total intervention group, the comparison group, or the Spanish- or English-speaking intervention subgroups. Compared with the comparison group, the intervention group showed statistically significant improvement on five of the eight SF-36 measures, and no improvement on the sleep quality or family harmony items. CONCLUSIONS: MBSR may be an effective behavioral medicine program for Spanish- and English-speaking inner-city medical patients. Suggestions are given for future research to help clarify the program’s effectiveness for this population.

This study examined the effects of mindfulness-based stress reduction (MBSR) on health-related quality of life and physical and psychological symptomatology in a heterogeneous patient population. Patients (n=136) participated in an 8-week MBSR program and were required to practice 20 min of meditation daily. Pre- and post-intervention data were collected by using the Short-Form Health Survey (SF-36), Medical Symptom Checklist (MSCL) and Symptom Checklist-90 Revised (SCL-90-R). Health-related quality of life was enhanced as demonstrated by improvement on all indices of the SF-36, including vitality, bodily pain, role limitations caused by physical health, and social functioning (all P&lt;.01). Alleviation of physical symptoms was revealed by a 28% reduction on the MSCL (P&lt;.0001). Decreased psychological distress was indicated on the SCL-90-R by a 38% reduction on the Global Severity Index, a 44% reduction on the anxiety subscale, and a 34% reduction on the depression subscale (all P&lt;.0001). One-year follow-up revealed maintenance of initial improvements on several outcome parameters. We conclude that a group mindfulness meditation training program can enhance functional status and well-being and reduce physical symptoms and psychological distress in a heterogeneous patient population and that the intervention may have long-term beneficial effects.
