OBJECTIVE: To investigate the effect of a short-term yoga-based lifestyle intervention on risk factors for cardiovascular disease (CVD) and markers of inflammation and endothelial function in overweight and obese men. DESIGN: Nonrandomized prospective lifestyle intervention study with pre-post design. SETTING AND LOCATION: Integral Health Clinic, an outpatient facility providing yoga-based lifestyle intervention programs for prevention and management of chronic diseases. SUBJECTS: Overweight and obese men (n=51) were enrolled in the study. Subjects who were physically unable to participate and those participating in other interventions were excluded from the study. INTERVENTION: A pretested intervention program including asanas (physical postures), pranayama (breathing exercises), group discussions, lectures, and individualized advice. OUTCOME MEASURES: The primary outcome measure was weight loss, and the secondary outcome measures were clinical and laboratory correlates of CVD risk, levels of interleukin-6 (IL-6), adiponectin, and endothelin-1 (ET-1). RESULTS: Men (n=51, body mass index [BMI] 26.26±2.42 kg/m(2)) were enrolled and underwent a yoga-based lifestyle intervention for 10 days. Of 51 subjects, 30 completed the study. There was a significant reduction in weight from Baseline to Day 10 (74.60±7.98, 72.69±8.37 kg, p<0.001, respectively), BMI (26.26±2.42, 25.69±2.47 kg/m(2), p<0.001, respectively), and systolic BP (121.73±11.58, 116.73±9.00, p=0.042, respectively). There was a significant reduction in plasma IL-6 from Baseline to Day 10 (median 2.24 vs. 1.26 pg/mL, respectively, p=0.012). There was a significant increase in the plasma adiponectin from Baseline to Day 10 (median 4.95 vs. 6.26 μg/mL, respectively, p=0.014). Plasma ET-1 level remained unchanged. CONCLUSION: These findings suggest that even a short-term yoga-based lifestyle intervention may be an important modality to reduce the risk for CVD as indicated by weight loss, reduction in systolic blood pressure, an increase in adiponectin, and decrease in IL-6 in overweight and obese men.
Some children show emotion that is not consistent with normative appraisal of the context and can therefore be defined as context inappropriate (CI). The authors used individual growth curve modeling and hierarchical multiple regression analyses to examine whether CI anger predicts differences in hypothalamic-pituitary-adrenal axis activity, as manifest in salivary cortisol measures. About 23% of the 360 children (ages 6-10 years, primarily 7-8) showed at least 1 expression of CI anger in situations designed to elicit positive affect. Expression of anger across 2 positive assessments was less common (around 4%). CI anger predicted the hypothesized lower levels of cortisol beyond that attributed to context appropriate anger. Boys' CI anger predicted lower morning cortisol and flatter slopes. Results suggest that this novel approach to studying children's emotion across varying contexts can provide insight into affective style.
OBJECTIVES: Randomized controlled studies on the effectiveness of body-oriented methods of treatment for children with attention-deficit hyperactivity disorder (ADHD) are lacking. Our aim was to compare the effectiveness of two methods of treatment (yoga for children vs. conventional motor exercises) in a randomized controlled pilot study. METHODS: Nineteen children with a clinical diagnosis of ADHD (according to ICD-10 criteria) were included and randomly assigned to treatment conditions according to a 2x2 cross-over design. Effects of treatment were analyzed by means of an analysis of variance for repeated measurements. RESULTS: For all outcome measures (test scores on an attention task, and parent ratings of ADHD symptoms) the yoga training was superior to the conventional motor training, with effect sizes in the medium-to-high range (0.60-0.97). All children showed sizable reductions in symptoms over time, and at the end of the study, the group means for the ADHD scales did not differ significantly from those for a representative control group. Furthermore, the training was particularly effective for children undergoing pharmacotherapy (MPH). CONCLUSIONS: The findings from this pilot study demonstrate that yoga can be an effective complementary or concomitant treatment for attention-deficit hyperactivity disorder. The study advocates further research into the impact of yoga or body-oriented therapies on the prevention and treatment of ADHD.
Neurophenomenological studies seek to utilize first-person self-report to elucidate cognitive processes related to physiological data. Grounded theory offers an approach to the qualitative analysis of self-report, whereby theoretical constructs are derived from empirical data. Here we used grounded theory methodology (GTM) to assess how the first-person experience of meditation relates to neural activity in a core region of the default mode network—the posterior cingulate cortex (PCC). We analyzed first-person data consisting of meditators' accounts of their subjective experience during runs of a real time fMRI neurofeedback study of meditation, and third-person data consisting of corresponding feedback graphs of PCC activity during the same runs. We found that for meditators, the subjective experiences of “undistracted awareness” such as “concentration” and “observing sensory experience,” and “effortless doing” such as “observing sensory experience,” “not efforting,” and “contentment,” correspond with PCC deactivation. Further, the subjective experiences of “distracted awareness” such as “distraction” and “interpreting,” and “controlling” such as “efforting” and “discontentment,” correspond with PCC activation. Moreover, we derived several novel hypotheses about how specific qualities of cognitive processes during meditation relate to PCC activity, such as the difference between meditation and “trying to meditate.” These findings offer novel insights into the relationship between meditation and mind wandering or self-related thinking and neural activity in the default mode network, driven by first-person reports.
OBJECTIVE: This study was undertaken to identify brain structures associated with emotion in normal elderly subjects. METHOD: Eight normal subjects aged 55-78 years were shown film clips intended to provoke the emotions of happiness, fear, or disgust as well as a neutral state. During emotional activation, regional cerebral blood flow was measured with the use of [15O]H2O positron emission tomography imaging, and subjective emotional responses were recorded. Data were analyzed by subtracting the values during the neutral condition from the values in the various emotional activations. RESULTS: The stimuli produced a general activation in visual pathways that included the primary and secondary visual cortex, involving regions associated with object and spatial recognition. In addition, the specific emotions produced different regional limbic activations, which suggests that different pathways may be used for different types of emotional stimuli. CONCLUSIONS: Emotional activation in normal elderly subjects was associated with increases in blood flow in limbic and paralimbic brain structures. Brain activation may be specific to the emotion being elicited but probably involves complex sensory, association, and memory circuitry. Further studies are needed to identify activations that are specific for emotion.
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.
Mindfulness, a concept originally derived from Buddhist psychology, is essential for some well-known clinical interventions. Therefore an instrument for measuring mindfulness is useful. We report here on two studies constructing and validating the Freiburg Mindfulness Inventory (FMI) including a short form. A preliminary questionnaire was constructed through expert interviews and extensive literature analysis and tested in 115 subjects attending mindfulness meditation retreats. This psychometrically sound 30-item scale with an internal consistency of Cronbach alpha = .93 was able to significantly demonstrate the increase in mindfulness after the retreat and to discriminate between experienced and novice meditators. In a second study we broadened the scope of the concept to 86 subjects without meditation experience, 117 subjects with clinical problems, and 54 participants from retreats. Reducing the scale to a short form with 14 items resulted in a semantically robust and psychometrically stable (alpha = .86) form. Correlation with other relevant constructs (self-awareness, dissociation, global severity index, meditation experience in years) was significant in the medium to low range of correlations and lends construct validity to the scale. Principal Component Analysis suggests one common factor. This short scale is sensitive to change and can be used also with subjects without previous meditation experience.
BACKGROUND: Many antidepressant medications (ADM) are associated with disruptions in sleep continuity that can compromise medication adherence and impede successful treatment. The present study investigated whether mindfulness meditation (MM) training could improve self-reported and objectively measured polysomnographic (PSG) sleep profiles in depressed individuals who had achieved at least partial remission with ADM, but still had residual sleep complaints. METHODS: Twenty-three ADM users with sleep complaints were randomized into an 8-week Mindfulness-Based Cognitive Therapy (MBCT) course or a waitlist control condition. Pre-post measurements included PSG sleep studies and subjectively reported sleep, residual depression symptoms. RESULTS: Compared to controls, the MBCT participants improved on both PSG and subjective measures of sleep. They showed a pattern of decreased wake time and increased sleep efficiency. Sleep depth, as measured by stage 1 and slow-wave sleep, did not change as a result of mindfulness training. CONCLUSIONS: MM is associated with increases in both objectively and subjectively measured sleep continuity in ADM users. MM training may serve as more desirable and cost-effective alternative to discontinuation or supplementation with hypnotics, and may contribute to a more sustainable recovery from depression.

Mindfulness-based interventions have been shown to alleviate symptoms of a wide range of physical and mental health conditions. Regular between-session practice of mindfulness meditation is among the key factors proposed to produce the therapeutic benefits of mindfulness-based programs. This article reviews the mindfulness intervention literature with a focus on the status of home practice research and the relationship of practice to mindfulness program outcomes. Of 98 studies reviewed, nearly one-quarter (N = 24) evaluated the associations between home practice and measures of clinical functioning, with just over half (N = 13) demonstrating at least partial support for the benefits of practice. These findings indicate a substantial disparity between what is espoused clinically and what is known empirically about the benefits of mindfulness practice. Improved methodologies for tracking and evaluating the effects of home practice are recommended.
<p>The study and practice of mindfulness is rapidly expanding in Western psychology. Recently developed self-report measures of mindfulness were derived from Western operationalizations and cross-cultural validation of many of these measures is lacking, particularly in Buddhist cultures. Therefore, this study examined the measurement equivalence of the Kentucky Inventory of Mindfulness Skills (KIMS) and Mindful Attention Awareness Scale (MAAS) among Thai (n=385) and American (n=365) college students. Multigroup confirmatory factor analysis models fit to the data revealed that the KIMS lacked configural invariance across groups, which precluded subsequent invariance tests, and although the MAAS demonstrated configural, metric, and partial scalar invariance, there was no significant latent mean MAAS difference between Thais and Americans. These findings suggest that Eastern and Western conceptualizations of mindfulness may have important differences. © 2009 Wiley Periodicals, Inc. J Clin Psychol 65: 1–23, 2009.</p>
<p>Mindfulness training may disrupt the risk chain of stress-precipitated alcohol relapse. In 2008, 53 alcohol-dependent adults (mean age = 40.3) recruited from a therapeutic community located in the urban southeastern U.S. were randomized to mindfulness training or a support group. Most participants were male (79.2%), African American (60.4%), and earned less than $20,000 annually (52.8%). Self-report measures, psychophysiological cue-reactivity, and alcohol attentional bias were analyzed via repeated measures ANOVA. Thirty-seven participants completed the interventions. Mindfulness training significantly reduced stress and thought suppression, increased physiological recovery from alcohol cues, and modulated alcohol attentional bias. Hence, mindfulness training appears to target key mechanisms implicated in alcohol dependence, and therefore may hold promise as an alternative treatment for stress-precipitated relapse among vulnerable members of society. Keywords--alcohol dependence, attentional bias, heart-rate variability, mindfulness, stress, thought suppression</p>
Positive affect elicited in a mother toward her newborn infant may be one of the most powerful and evolutionarily preserved forms of positive affect in the emotional landscape of human behavior. This study examined the neurobiology of this form of positive emotion and in so doing, sought to overcome the difficulty of eliciting robust positive affect in response to visual stimuli in the physiological laboratory. Six primiparous human mothers with no indications of postpartum depression brought their infants into the laboratory for a photo shoot. Approximately 6 weeks later, they viewed photographs of their infant, another infant, and adult faces during acquisition of functional magnetic resonance images (fMRI). Mothers exhibited bilateral activation of the orbitofrontal cortex (OFC) while viewing pictures of their own versus unfamiliar infants. While in the scanner, mothers rated their mood more positively for pictures of their own infants than for unfamiliar infants, adults, or at baseline. The orbitofrontal activation correlated positively with pleasant mood ratings. In contrast, areas of visual cortex that also discriminated between own and unfamiliar infants were unrelated to mood ratings. These data implicate the orbitofrontal cortex in a mother's affective responses to her infant, a form of positive emotion that has received scant attention in prior human neurobiological studies. Furthermore, individual variations in orbitofrontal activation to infant stimuli may reflect an important dimension of maternal attachment.
Neuroimage phenotyping for psychiatric and neurological disorders is performed using voxelwise analyses also known as voxel based analyses or morphometry (VBM). A typical voxelwise analysis treats measurements at each voxel (e.g., fractional anisotropy, gray matter probability) as outcome measures to study the effects of possible explanatory variables (e.g., age, group) in a linear regression setting. Furthermore, each voxel is treated independently until the stage of correction for multiple comparisons. Recently, multi-voxel pattern analyses (MVPA), such as classification, have arisen as an alternative to VBM. The main advantage of MVPA over VBM is that the former employ multivariate methods which can account for interactions among voxels in identifying significant patterns. They also provide ways for computer-aided diagnosis and prognosis at individual subject level. However, compared to VBM, the results of MVPA are often more difficult to interpret and prone to arbitrary conclusions. In this paper, first we use penalized likelihood modeling to provide a unified framework for understanding both VBM and MVPA. We then utilize statistical learning theory to provide practical methods for interpreting the results of MVPA beyond commonly used performance metrics, such as leave-one-out-cross validation accuracy and area under the receiver operating characteristic (ROC) curve. Additionally, we demonstrate that there are challenges in MVPA when trying to obtain image phenotyping information in the form of statistical parametric maps (SPMs), which are commonly obtained from VBM, and provide a bootstrap strategy as a potential solution for generating SPMs using MVPA. This technique also allows us to maximize the use of available training data. We illustrate the empirical performance of the proposed framework using two different neuroimaging studies that pose different levels of challenge for classification using MVPA.
Interest in mindfulness as a tool to improve health and well-being has increased rapidly over the past two decades. Limited qualitative research has been conducted on mindfulness and health. This study utilized in-depth interviews to explore the context, perceptions, and experiences of a sub-set of participants engaged in an acceptability study of mindfulness-based stress reduction (MBSR) among urban youth. Content analysis revealed that all in-depth interview participants reported experiencing some form of positive benefit and enhanced self-awareness as a result of MBSR program participation. Significant variation in the types and intensity of changes occurring was identified, ranging from a reframing and reduction of daily stressors to transformational shifts in life orientation and well-being. Variations in perceptions of and experiences with mindfulness should be studied in further depth in the context of prospective intervention research, including their potentially differential influence on mental and physical health outcomes.
<p>BACKGROUND: All therapists direct their attention in some manner during psychotherapy. A special form of directing attention, 'mindfulness', is recommended. This study aimed to examine whether, and to what extent, promoting mindfulness in psychotherapists in training (PiT) influences the treatment results of their patients. METHODS: The therapeutic course and treatment results of 124 inpatients, who were treated for 9 weeks by 18 PiTs, were compared. The PiTs were randomly assigned to 1 of 2 groups: (i) those practicing Zen meditation (MED; n = 9 or (ii) control group, which did not perform meditation (noMED; n = 9). The results of treatment (according to the intent-to-treat principle) were examined using the Session Questionnaire for General and Differential Individual Psychotherapy (STEP), the Questionnaire of Changes in Experience and Behavior (VEV) and the Symptom Checklist (SCL-90-R). RESULTS: Compared to the noMED group (n = 61), the patients of PiTs from the MED group (n = 63) had significantly higher evaluations (according to the intent-to-treat principle) for individual therapy on 2 STEP scales, clarification and problem-solving perspectives. Their evaluations were also significantly higher for the entire therapeutic result on the VEV. Furthermore, the MED group showed greater symptom reduction than the noMED group on the Global Severity Index and 8 SCL-90-R scales, including Somatization, Insecurity in Social Contact, Obsessiveness, Anxiety, Anger/Hostility, Phobic Anxiety, Paranoid Thinking and Psychoticism. CONCLUSIONS: This study indicates that promoting mindfulness in PiTs could positively influence the therapeutic course and treatment results in their patients.</p>
Objectives: Considerable morbidity persists among survivors of breast cancer (BC) including high levels of psychological stress, anxiety, depression, fear of recurrence, and physical symptoms including pain, fatigue, and sleep disturbances, and impaired quality of life. Effective interventions are needed during this difficult transitional period. Methods: We conducted a randomized controlled trial of 84 female BC survivors (Stages 0–III) recruited from the H. Lee Moffitt Cancer and Research Institute. All subjects were within 18 months of treatment completion with surgery and adjuvant radiation and/or chemotherapy. Subjects were randomly assigned to a 6-week Mindfulness-Based Stress Reduction (MBSR) program designed to self-regulate arousal to stressful circumstances or symptoms (n=41) or to usual care (n=43). Outcome measures compared at 6 weeks by random assignment included validated measures of psychological status (depression, anxiety, perceived stress, fear of recurrence, optimism, social support) and psychological and physical subscales of quality of life (SF-36). Results: Compared with usual care, subjects assigned to MBSR(BC) had significantly lower (two-sided p<0.05) adjusted mean levels of depression (6.3 vs 9.6), anxiety (28.3 vs 33.0), and fear of recurrence (9.3 vs 11.6) at 6 weeks, along with higher energy (53.5 vs 49.2), physical functioning (50.1 vs 47.0), and physical role functioning (49.1 vs 42.8). In stratified analyses, subjects more compliant with MBSR tended to experience greater improvements in measures of energy and physical functioning. Conclusions: Among BC survivors within 18 months of treatment completion, a 6-week MBSR(BC) program resulted in significant improvements in psychological status and quality of life compared with usual care.

<p>OBJECTIVES: The study objectives were to develop and objectively assess the therapeutic effect of a novel movement-based complementary and alternative medicine approach for children with an autism-spectrum disorder (ASD). DESIGN: A within-subject analysis comparing pre- to post-treatment scores on two standard measures of childhood behavioral problems was used. SETTINGS AND LOCATION: The intervention and data analysis occurred at a tertiary care, medical school teaching hospital. SUBJECTS: Twenty-four (24) children aged 3-16 years with a diagnosis of an ASD comprised the study group. INTERVENTION: The efficacy of an 8-week multimodal yoga, dance, and music therapy program based on the relaxation response (RR) was developed and examined. OUTCOME MEASURES: The study outcome was measured using The Behavioral Assessment System for Children, Second Edition (BASC-2) and the Aberrant Behavioral Checklist (ABC). RESULTS: Robust changes were found on the BASC-2, primarily for 5-12-year-old children. Unexpectedly, the post-treatment scores on the Atypicality scale of the BASC-2, which measures some of the core features of autism, changed significantly (p=0.003). CONCLUSIONS: A movement-based, modified RR program, involving yoga and dance, showed efficacy in treating behavioral and some core features of autism, particularly for latency-age children.</p>
This study, based on a sample of 172 children, examined the relation between average afternoon salivary cortisol levels measured at home at age 4.5 years and socioemotional adjustment a year and a half later, as reported by mothers, fathers, and teachers. Cortisol levels were hypothesized to be positively associated with withdrawal-type behaviors (e.g., internalizing, social wariness) and inversely related to approach-type behaviors, both negative and positive (e.g., externalizing, school engagement). Higher cortisol levels at age 4.5 predicted more internalizing behavior and social wariness as reported by teachers and mothers, although child gender moderated the relation between cortisol and mother report measures. An inverse relation was found between boys' cortisol levels and father report of externalizing behavior. A marginal inverse relation was found between child cortisol levels and teacher report of school engagement. Behavior assessed concurrently with cortisol collection did not account for the prospective relations observed,suggesting that cortisol adds uniquely to an understanding of behavioral development.
<p>Recent literature has described how the capacity for concurrent self-assessment—ongoing moment-to-moment self-monitoring—is an important component of the professional competence of physicians. Self-monitoring refers to the ability to notice our own actions, curiosity to examine the effects of those actions, and willingness to use those observations to improve behavior and thinking in the future. Self-monitoring allows for the early recognition of cognitive biases, technical errors, and emotional reactions and may facilitate self-correction and development of therapeutic relationships. Cognitive neuroscience has begun to explore the brain functions associated with self-monitoring, and the structural and functional changes that occur during mental training to improve attentiveness, curiosity, and presence. This training involves cultivating habits of mind such as experiencing information as novel, thinking of “facts” as conditional, seeing situations from multiple perspectives, suspending categorization and judgment, and engaging in self-questioning. The resulting awareness is referred to as mindfulness and the associated moment-to-moment self-monitoring as mindful practice—in contrast to being on “automatic pilot” or “mindless” in one's behavior. This article is a preliminary exploration into the intersection of educational assessment, cognitive neuroscience, and mindful practice, with the hope of promoting ways of improving clinicians' capacity to self-monitor during clinical practice, and, by extension, improve the quality of care that they deliver.</p>
OBJECTIVES: Affective neuroscience research that investigates core symptoms of pediatric bipolar disorder (PBD) may be effective in differentiating PBD phenotypes. The current study used affect-modulated startle to examine potential differences in reactivity to emotional stimuli (reward and punishment) in narrow and broad phenotype PBD and controls. METHODS: Thirty children meeting DSM-IV bipolar disorder criteria (i.e. narrow phenotype PBD with defined manic episodes with elevated/expansive mood), 19 children meeting criteria for severe mood dysregulation (i.e. broad phenotype with chronic irritability, hyper-reactivity, and hyperarousal), and 19 controls completed a lottery startle paradigm involving reward (money) and punishment (loud noise). Startle probes were presented during anticipation of the emotional stimulus, immediately following the presentation of the stimulus, or during return to baseline following the stimulus. RESULTS: By self-report, patients and controls found the putative punishment to be preferable to the neutral condition. In the reward condition, patient samples reported greater arousal than did controls, but no between-group differences were found on the magnitude of startle response during the reward, punishment, or neutral conditions. CONCLUSIONS: The failure to find differences in affect-modulated startle between control children and those with narrow or broad PBD phenotypes speaks to the methodological challenges associated with studying reward mechanisms in PBD. Alternative paradigms that focus on different aspects of reward mechanisms are discussed.
The authors examine the facet structure of mindfulness using five recently developed mindfulness questionnaires. Two large samples of undergraduate students completed mindfulness questionnaires and measures of other constructs. Psychometric properties of the mindfulness questionnaires were examined, including internal consistency and convergent and discriminant relationships with other variables. Factor analyses of the combined pool of items from the mindfulness questionnaires suggested that collectively they contain five clear, interpretable facets of mindfulness. Hierarchical confirmatory factor analyses suggested that at least four of the identified factors are components of an overall mindfulness construct and that the factor structure of mindfulness may vary with meditation experience. Mindfulness facets were shown to be differentially correlated in expected ways with several other constructs and to have incremental validity in the prediction of psychological symptoms. Findings suggest that conceptualizing mindfulness as a multifaceted construct is helpful in understanding its components and its relationships with other variables.
