RESUMEN

Psychosocial interventions for people with chronic pain produce significant improvements in outcomes, but these effects on average are modest with much variability in the benefits conferred on individuals. To enhance the magnitude of treatment effects, characteristics of people that might predict the degree to which they respond more or less well could be identified. People with chronic low back pain (N = 521) participated in a randomized controlled trial which compared cognitive therapy, mindfulness-based stress reduction, behavior therapy and treatment as usual. Hypotheses regarding predictors and/or moderators were based on the Limit, Activate, and Enhance model; developed to predict and explain moderators/predictors of psychosocial pain treatments. Results were: 1) low levels of cognitive/behavioral function at pre-treatment predicted favorable pre- to post-treatment outcomes; 2) favorable expectations of benefit from treatment and sound working alliances predicted favorable pre- to post-treatment outcomes; 3) women benefited more than men. These effects emerged without regard to treatment condition. Of note, high levels of cognitive/behavioral function at pre-treatment predicted favorable outcomes only for people in the treatment as usual condition. Analyses identified a set of psychosocial variables that may act as treatment predictors across cognitive therapy, mindfulness-based stress reduction and behavior therapy, as hypothesized by the Limit, Activate, and Enhance model if these 3 treatments operate via similar mechanisms. Findings point toward people who may and who may not benefit fully from the 3 psychosocial treatments studied here, and so may guide future research on matching people to these kinds of psychosocial approaches or to other (eg, forced-based interventions) non-psychosocial approaches. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT02133976. PERSPECTIVE: This article examines potential predictors/moderators of response to psychosocial treatments for chronic pain. Results could guide efforts to match people to the most effective treatment type or kind.

RESUMEN

OBJECTIVE: Cognitive therapy (CT), mindfulness-based stress reduction (MBSR), and behavior therapy (BT) for chronic pain treatment produce outcome improvements. Evidence also suggests that changes in putative therapeutic mechanisms are associated with changes in outcomes. Nonetheless, methodological limitations preclude clear understanding of how psychosocial chronic pain treatments work. In this comparative mechanism study, we examined evidence for specific and shared mechanism effects across the three treatments. METHOD: CT, MBSR, BT, and treatment as usual (TAU) were compared in people with chronic low back pain (N = 521). Eight individual sessions were administered with weekly assessments of "specific" mechanisms (pain catastrophizing, mindfulness, behavior activation) and outcomes. RESULTS: CT, MBSR, and BT produced similar pre- to posttreatment effects on all mechanism variables, and all three active treatments produced greater improvements than TAU. Participant ratings of expectations of benefit and working alliance were similar across treatments. Lagged and cross-lagged analyses revealed that prior week changes in both mechanism and outcome factors predicted next week changes in their counterparts. Analyses of variance contributions suggested that changes in pain catastrophizing and pain self-efficacy were consistent unique predictors of subsequent outcome changes. CONCLUSIONS: Findings support the operation of shared mechanisms over specific ones. Given significant lagged and cross-lagged effects, unidirectional conceptualizations-mechanism to outcome-need to be expanded to include reciprocal effects. Thus, prior week changes in pain-related cognitions could predict next week changes in pain interference which in turn could predict next week changes in pain-related cognitions, in what may be an upward spiral of improvement.

RESUMEN

Mindfulness-based cognitive therapy (MBCT) is a promising intervention for reducing depressive symptoms in individuals with comorbid chronic disease, but the program's attendance demands make it inaccessible to many who might benefit. We tested the feasibility, acceptability, safety, and preliminary efficacy of an abbreviated, telephone-delivered adaptation of the in-person mindfulness-based cognitive therapy (MBCT-T) program in a sample of patients with depressive symptoms and hypertension. Participants (n = 14; 78.6% female, mean age = 60.6) with mild to moderate depressive symptoms and hypertension participated in the 8-week MBCT-T program. Feasibility was indexed via session attendance and home-based practice completion. Acceptability was indexed via self-reported satisfaction scores. Safety was assessed via reports of symptomatic decline or need for additional mental health treatment. Depressive symptoms (Quick Inventory of Depressive Symptomatology-Self-Report [QIDS-SR]) and anxiety (Hospital Anxiety and Depression Scale-Anxiety subscale; HADS-A) were assessed at baseline and immediately following the intervention. Sixty-four percent of participants (n = 9) attended ≥4 intervention sessions. Seventy-one percent (n = 6) of participants reported completing all assigned formal home practice and 89.2% (n = 8) reported completing all assigned informal practice. Participants were either very satisfied (75%; n = 6) or mostly satisfied (25%; n = 2) with the intervention. There were no adverse events or additional need for mental health treatment. Depressive symptom scores were 4.09 points lower postintervention (p = .004). Anxiety scores were 3.18 points lower postintervention (p = .039). Results support the feasibility, acceptability, safety, and preliminary efficacy of an abbreviated, telephone-delivered version of MBCT for reducing depressive and anxiety symptoms in individuals with co-occurring chronic disease.

RESUMEN

ABSTRACT: Trials of cognitive therapy (CT), mindfulness-based stress reduction (MBSR), and behavior therapy (BT) suggest that all 3 treatments produce reductions in pain and improvements in physical function, mood, and sleep disturbance in people with chronic pain conditions. Fewer studies have compared the relative efficacies of these treatments. In this randomized controlled study, we compared CT, MBSR, BT, and treatment as usual (TAU) in a sample of people with chronic low back pain (N = 521). Eight individual sessions were administered with weekly assessments of outcomes. Consistent with the prior work, we found that CT, MBSR, and BT produced similar pretreatment to posttreatment effects on all outcomes and revealed similar levels of maintenance of treatment gains at 6-month follow-up. All 3 active treatments produced greater improvements than TAU. Weekly assessments allowed us to assess rates of change; ie, how quickly a given treatment produced significant differences, compared with TAU, on a given outcome. The 3 treatments differed significantly from TAU on average by session 6, and this rate of treatment effect was consistent across all treatments. Results suggest the possibility that the specific techniques included in CT, MBSR, and BT may be less important for producing benefits than people participating in any techniques rooted in these evidence-based psychosocial treatments for chronic pain.

RESUMEN

OBJECTIVE: Posttraumatic stress disorder (PTSD) is often difficult to treat, and many patients do not achieve full remission. Complementary and integrative health approaches, such as mindfulness meditation, are intended to be integrated with evidence-based treatment. This study examined the efficacy of mindfulness-based stress reduction (MBSR) in the treatment of PTSD in U.S. military veterans. METHODS: Veterans with a diagnosis of PTSD (N=214) were randomly assigned to either 90-minute group MBSR or present-centered group therapy (PCGT) for eight weeks. Follow-up assessments were obtained at baseline and weeks 3, 6, 9 (primary endpoint), and 16. RESULTS: Both the MBSR and PCGT groups achieved significant improvement in PTSD as measured by the Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV), with no statistically significant differences between groups. However, compared with PCGT, the MBSR group showed a statistically significant improvement in PTSD on the self-reported PTSD Checklist for DSM-IV over the nine weeks. This difference was not maintained posttreatment, at week 16. Strengths of the study include its large sample size, multisite design, active control group, single-blind outcome ratings, fidelity monitoring, large minority representation, and randomized approach. The study was limited by its high attrition rate and low representation of women. CONCLUSION: Both MBSR and PCGT appear to have beneficial effects in treating PTSD in veterans, with greater improvement observed in self-reported PTSD symptoms in the MBSR group. No differences between groups were observed on the CAPS-IV scale.

RESUMEN

INTRODUCTION: There is evidence that Yoga may be helpful as an aid for smoking cessation. Yoga has been shown to reduce stress and negative mood and may aid weight control, all of which have proven to be barriers to quitting smoking. This study is the first rigorous, randomized clinical trial of Yoga as a complementary therapy for smokers attempting to quit. METHODS: Adult smokers (N = 227; 55.5% women) were randomized to an 8-week program of cognitive-behavioral smoking cessation and either twice-weekly Iyengar Yoga or general Wellness classes (control). Assessments included cotinine-verified 7-day point prevalence abstinence at week 8, 3-month, and 6-month follow-ups. RESULTS: At baseline, participants' mean age was 46.2 (SD = 12.0) years and smoking rate was 17.3 (SD = 7.6) cigarettes/day. Longitudinally adjusted models of abstinence outcomes demonstrated significant group effects favoring Yoga. Yoga participants had 37% greater odds of achieving abstinence than Wellness participants at the end of treatment (EOT). Lower baseline smoking rates (≤10 cigarettes/day) were also associated with higher likelihood of quitting if given Yoga versus Wellness (OR = 2.43, 95% CI = 1.09% to 6.30%) classes at EOT. A significant dose effect was observed for Yoga (OR = 1.12, 95% CI = 1.09% to 1.26%), but not Wellness, such that each Yoga class attended increased quitting odds at EOT by 12%. Latent Class Modeling revealed a 4-class model of distinct quitting patterns among participants. CONCLUSIONS: Yoga appears to increase the odds of successful smoking abstinence, particularly among light smokers. Additional work is needed to identify predictors of quitting patterns and inform adjustments to therapy needed to achieve cessation and prevent relapse. IMPLICATIONS: This study adds to our knowledge of the types of physical activity that aid smoking cessation. Yoga increases the odds of successful smoking abstinence, and does so in a dose-response manner. This study also revealed four distinct patterns of smoking behavior among participants relevant to quitting smoking. Additional work is needed to determine whether variables that are predictive of these quitting patterns can be identified, which might suggest modifications to therapy for those who are unable to quit.

RESUMEN

OBJECTIVE: We investigated common and dissociable neural and psychological correlates of two widely used meditation-based stress reduction programs. METHODS: Participants were randomized to the Relaxation Response (RR; n = 18; 56% female) or the Mindfulness-Based Stress Reduction (MBSR; n = 16; 56% female) programs. Both programs use a "bodyscan" meditation; however, the RR program explicitly emphasizes physical relaxation during this practice, whereas the MBSR program emphasizes mindful awareness with no explicit relaxation instructions. After the programs, neural activity during the respective meditation was investigated using functional magnetic resonance imaging. RESULTS: Both programs were associated with reduced stress (for RR, from 14.1 ± 6.6 to 11.3 ± 5.5 [Cohen's d = 0.50; for MBSR, from 17.7 ± 5.7 to 11.9 ± 5.0 [Cohen's d = 1.02]). Conjunction analyses revealed functional coupling between ventromedial prefrontal regions and supplementary motor areas (p < .001). The disjunction analysis indicated that the RR bodyscan was associated with stronger functional connectivity of the right inferior frontal gyrus-an important hub of intentional inhibition and control-with supplementary motor areas (p < .001, family-wise error [FWE] rate corrected). The MBSR program was uniquely associated with improvements in self-compassion and rumination, and the within-group analysis of MBSR bodyscan revealed significant functional connectivity of the right anterior insula-an important hub of sensory awareness and salience-with pregenual anterior cingulate during bodyscan meditation compared with rest (p = .03, FWE corrected). CONCLUSIONS: The bodyscan exercises in each program were associated with both overlapping and differential functional coupling patterns, which were consistent with each program's theoretical foundation. These results may have implications for the differential effects of these programs for the treatment of diverse conditions.

RESUMEN

OBJECTIVES: Pain-related cognitive content (what people think about pain) and cognitive processes (how people think about pain; what they do with their pain-related thoughts) and their interaction are hypothesized to play distinct roles in patient function. However, questions have been raised regarding whether it is possible or practical to assess cognitive content and cognitive process as distinct domains. The aim of this study was to determine the extent to which measures that seem to assess mostly pain-related cognitive content, cognitive processes, and content and process, are relatively independent from each other and contribute unique variance to the prediction of patient function. MATERIALS AND METHODS: Individuals with chronic low back pain (N=165) participating in an ongoing RCT were administered measures of cognitions, pain, and function (depressive symptoms and pain interference) pretreatment. RESULTS: Analyses provided support for the hypothesis that cognitive content and cognitive process, while related, can be assessed as distinct components. However, the measure assessing a cognitive process-mindfulness-evidenced relatively weak associations with function, especially compared with the stronger and more consistent findings for the measures of content (catastrophizing and self-efficacy). DISCUSSION: The results provide preliminary evidence for the possibility that mindfulness could have both benefits and costs. Research to evaluate this possibility is warranted.

RESUMEN

OBJECTIVE: Our objective was to develop an instrument that can measure outcome expectations of yoga and to evaluate the instrument for internal consistency and initial construct validity. METHODS: A 20-item scale was developed to assess physical, mental, and spiritual health benefits related to yoga practice among adults. The scale was tested in a baseline survey with adults participating in a clinical trial. Principal component analysis was used to investigate the internal structure of the measure. Outcome expectations for yoga were examined for demographic differences. RESULTS: The sample (N = 185) was 54% women, 89% white and had a mean age of 46 years. The final 20-item scale had high item loadings that ranged from .57 to .88 with a Cronbach's alpha value of .96. Significant differences were found in outcome expectation score by sex. CONCLUSION: This newly developed scale can be used to assess outcome expectations for yoga and tailor interventions to promote adherence to yoga practice.

RESUMEN

OBJECTIVE: Brain imaging studies in patients with post-traumatic stress disorder (PTSD) have implicated a circuitry of brain regions including the medial prefrontal cortex, amygdala, hippocampus, parietal cortex, and insula. Pharmacological treatment studies have shown a reversal of medial prefrontal deficits in response to traumatic reminders. Mindfulness-based stress reduction (MBSR) is a promising non-pharmacologic approach to the treatment of anxiety and pain disorders. The purpose of this study was to assess the effects of MBSR on PTSD symptoms and brain response to traumatic reminders measured with positron-emission tomography (PET) in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) combat veterans with PTSD. We hypothesized that MBSR would show increased prefrontal response to stress and improved PTSD symptoms in veterans with PTSD. METHOD: Twenty-six OEF/OIF combat veterans with PTSD who had recently returned from a combat zone were block randomized to receive eight sessions of MBSR or present-centered group therapy (PCGT). PTSD patients underwent assessment of PTSD symptoms with the Clinician-Administered PTSD Scale (CAPS), mindfulness with the Five Factor Mindfulness Questionnaire (FFMQ) and brain imaging using PET in conjunction with exposure to neutral and Iraq combat-related slides and sound before and after treatment. Nine patients in the MBSR group and 8 in the PCGT group completed all study procedures. RESULTS: Post-traumatic stress disorder patients treated with MBSR (but not PCGT) had an improvement in PTSD symptoms measured with the CAPS that persisted for 6 months after treatment. MBSR also resulted in an increase in mindfulness measured with the FFMQ. MBSR-treated patients had increased anterior cingulate and inferior parietal lobule and decreased insula and precuneus function in response to traumatic reminders compared to the PCGT group. CONCLUSION: This study shows that MBSR is a safe and effective treatment for PTSD. Furthermore, MBSR treatment is associated with changes in brain regions that have been implicated in PTSD and are involved in extinction of fear responses to traumatic memories as well as regulation of the stress response.

RESUMEN

INTRODUCTION: Smokers trying to quit encounter many challenges including nicotine withdrawal symptoms, cigarette craving, increased stress and negative mood and concern regarding weight gain. These phenomena make it difficult to successfully quit smoking. Studies in non-smoking populations show that yoga reduces stress and negative mood and improves weight control. By increasing mindfulness we anticipate that yoga may also improve smokers' ability to cope with the negative symptoms associated with quitting. Yoga may also improve cognitive deliberation which is needed to make effective choices and avoid smoking in tempting situations. METHODS/DESIGN: The BreathEasy study is a rigorous, randomized controlled clinical trial examining the efficacy of Iyengar yoga as a complementary therapy to cognitive-behavioral therapy for smoking cessation. All participants are given an 8-week program of smoking cessation classes, and are randomized to either twice weekly yoga (Yoga) or twice-weekly health and wellness classes which serve as a control for contact and participant burden (CTL). Assessments are conducted at baseline, 8 weeks, 3, 6, and 12 months of follow-up. The primary outcome is prolonged abstinence using an intention-to-treat approach. Multiple internal and external audits using blind data collection are employed to ensure treatment fidelity and reliability of study results. To understand why yoga may be more effective than CTL, we will examine the mechanisms of action (i.e., mediators) underlying intervention efficacy. We will examine the maintenance of yoga practice and smoking status at each follow-up. Focus groups and interviews will be used to enrich our understanding of the relationship of yoga practice and smoking abstinence. CONCLUSIONS: This study will provide a stringent test of the relative efficacy of yoga compared to a condition that controls for contact time and attention. The use of mixed methodology also provides the opportunity to validate existing knowledge about yoga and helps to explore new themes for future mindfulness and yoga research.

RESUMEN

Individuals can improve their levels of psychological well-being (PWB) through utilization of psychological interventions, including the practice of mindfulness meditation, which is defined as the non-judgmental awareness of experiences in the present moment. We recently reported that an 8-week-mindfulness-based stress reduction (MBSR) course lead to increases in gray matter concentration in several brain areas, as detected with voxel-based morphometry of magnetization prepared rapid acquisition gradient echo MRI scans, including the pons/raphe/locus coeruleus area of the brainstem. Given the role of the pons and raphe in mood and arousal, we hypothesized that changes in this region might underlie changes in well-being. A subset of 14 healthy individuals from a previously published data set completed anatomical MRI and filled out the PWB scale before and after MBSR participation. PWB change was used as the predictive regressor for changes in gray matter density within those brain regions that had previously shown pre- to post-MBSR changes. Results showed that scores on five PWB subscales as well as the PWB total score increased significantly over the MBSR course. The change was positively correlated with gray matter concentration increases in two symmetrically bilateral clusters in the brainstem. Those clusters appeared to contain the area of the pontine tegmentum, locus coeruleus, nucleus raphe pontis, and the sensory trigeminal nucleus. No clusters were negatively correlated with the change in PWB. This preliminary study suggests a neural correlate of enhanced PWB. The identified brain areas include the sites of synthesis and release of the neurotransmitters, norepinephrine and serotonin, which are involved in the modulation of arousal and mood, and have been related to a variety of affective functions as well as associated clinical dysfunctions.

RESUMEN

BACKGROUND: The reduction in adrenergic activity and anxiety associated with meditation may be beneficial for patients with implantable cardioverter defibrillators. PURPOSE: This study aims to determine the feasibility of a phone-delivered mindfulness intervention in patients with defibrillators and to obtain preliminary indications of efficacy on mindfulness and anxiety. METHODS: Clinically stable outpatients were randomized to a mindfulness intervention (eight weekly individual phone sessions) or to a scripted follow-up phone call. We used the Hospital Anxiety and Depression Scale and the Five Facets of Mindfulness to measure anxiety and mindfulness, and multivariate linear regression to estimate the intervention effect on pre-post-intervention changes in these variables. RESULTS: We enrolled 45 patients (23 mindfulness and 22 control; age, 43-83; 30 % women). Retention was 93 %; attendance was 94 %. Mindfulness (beta = 3.31; p = 0.04) and anxiety (beta = -1.15; p = 0.059) improved in the mindfulness group. CONCLUSIONS: Mindfulness training can be effectively phone-delivered and may improve mindfulness and anxiety in cardiac defibrillator outpatients.

RESUMEN

Diet may represent a modifiable prostate cancer risk factor, but a vegetable-based prostate-healthy diet is a major change for most men. We used a ratio of animal to vegetable proteins (A:V) to evaluate whether a comprehensive dietary change was self-sustaining following completion of 11 weekly dietary and cooking classes that integrated mindfulness training. Thirty-six men with recurring prostate cancer were randomized to the intervention or wait-list control. Assessments were at baseline, 3 months, and 6 months. Of 17 men randomized to the intervention, 14 completed the requirements. Nineteen were randomized to control and 17 completed requirements. Compared with controls, a significant postintervention (3 months) decrease in A:V in the intervention group (P=0.01) was self-maintained 3 months postintervention (P=0.049). At each assessment, A:V was correlated with lycopene, fiber, saturated fat, and dietary cholesterol, four dietary components linked to clinically relevant outcomes in prostate cancer. Change in A:V was also significantly correlated with changes in fiber, saturated fat, and dietary cholesterol intake. Participants reported regular mindfulness training practice, and there was a significant correlation between mindfulness training practice and changes in both initiation and maintenance of the change in A:V. These pilot results provide encouraging evidence for the feasibility of a dietary program that includes mindfulness training in supporting dietary change for men with recurrent prostate cancer and invite further study to explore the possible role of mindfulness training as a means of supporting both initiation of dietary changes and maintenance of those changes over time.

RESUMEN

OBJECTIVE: The purpose of the study was to examine weekly change in self-reported mindfulness and perceived stress in participants who completed an 8-week course in mindfulness-based stress reduction (MBSR). METHOD: Participants were 87 adults with problematic levels of stress related to chronic illness, chronic pain, and other life circumstances (mean age = 49 years, 67% female) participating in MBSR in an academic medical center. They completed weekly self-report assessments of mindfulness skills and perceived stress. It was hypothesized that significant improvement in mindfulness skills would precede significant change in stress. RESULTS: Mindfulness skills and perceived stress both changed significantly from pretreatment to posttreatment. Significant increases in mindfulness occurred by the second week of the program, whereas significant improvements in perceived stress did not occur until week 4. Extent of change in mindfulness skills during the first three weeks predicted change in perceived stress over the course of the intervention. CONCLUSIONS: Evidence that changes in mindfulness precede changes in perceived stress in a standard MBSR course is consistent with previous studies suggesting that improvements in mindfulness skills may mediate the effects of mindfulness training on mental health outcomes.

RESUMEN

BACKGROUND: This study evaluated the efficacy of a mindfulness training programme (mindfulness-based stress reduction (MBSR)) in improving asthma-related quality of life and lung function in patients with asthma. METHODS: A randomised controlled trial compared an 8-week MBSR group-based programme (n=42) with an educational control programme (n=41) in adults with mild, moderate or severe persistent asthma recruited at a university hospital outpatient primary care and pulmonary care clinic. Primary outcomes were quality of life (Asthma Quality of Life Questionnaire) and lung function (change from baseline in 2-week average morning peak expiratory flow (PEF)). Secondary outcomes were asthma control assessed by 2007 National Institutes of Health/National Heart Lung and Blood Institute guidelines, and stress (Perceived Stress Scale (PSS)). Follow-up assessments were conducted at 10 weeks, 6 and 12 months. RESULTS: At 12 months MBSR resulted in clinically significant improvements from baseline in quality of life (differential change in Asthma Quality of Life Questionnaire score for MBSR vs control: 0.66 (95% CI 0.30 to 1.03; p<0.001)) but not in lung function (morning PEF, PEF variability and forced expiratory volume in 1 s). MBSR also resulted in clinically significant improvements in perceived stress (differential change in PSS score for MBSR vs control: -4.5 (95% CI -7.1 to -1.9; p=0.001)). There was no significant difference (p=0.301) in percentage of patients in MBSR with well controlled asthma (7.3% at baseline to 19.4%) compared with the control condition (7.5% at baseline to 7.9%). CONCLUSIONS: MBSR produced lasting and clinically significant improvements in asthma-related quality of life and stress in patients with persistent asthma, without improvements in lung function.

RESUMEN

Background. Meditation practices are associated with a reduction in adrenergic activity that may benefit patients with severe cardiac arrhythmias. This paper describes the design and methods of a pilot study testing the feasibility of a phone-delivered mindfulness-based intervention (MBI) for treatment of anxiety in patients with implantable cardioverter defibrillators (ICDs). Design and Methods. Consecutive, clinically stable outpatients (n = 52) will be screened for study eligibility within a month of an ICD-related procedure or ICD shock and will be randomly assigned to MBI or to usual care. MBI patients will receive eight weekly individual phone sessions based on two mindfulness practices (awareness of breath and body scan) plus home practice with a CD for 20 minutes daily. Patients assigned to usual care will be offered the standard care planned by the hospital. Assessments will occur at baseline and at the completion of the intervention (between 9 and 12 weeks after randomization). The primary study outcome is feasibility; secondary outcomes include anxiety, mindfulness, and number of administered shocks during the intervention period. Conclusions. If proven feasible and effective, phone-delivered mindfulness-based interventions could improve psychological distress in ICD outpatients with serious cardiovascular conditions.

RESUMEN

The characteristics of dispositional mindfulness have rarely been explored in unhealthy populations. We sought to evaluate its association(s) with psychological morbidity and disease severity in 30 outpatients with implantable cardioverter defibrillators naïve to mindfulness training. We used the Five Facets of Mindfulness and the Hospital Anxiety and Depression Scale to measure dispositional mindfulness and anxiety/depression, respectively. Associations were estimated using linear regression models. Higher dispositional mindfulness was observed in patients with lower anxiety scores (ß = - 1.10, CI: -1.71, -0.49) and no history of depression (ß = - 7.95; CI: -14.31, -1.6) by univariate analysis. No associations were observed with disease severity or other covariates. In conclusion, psychological well-being and psychological morbidity, and not disease severity, appear to be associated with dispositional mindfulness in patients with implantable cardioverter defibrillators. Further research is needed to confirm these findings.

RESUMEN

OBJECTIVE: The aim of this study was to analyze the effect of participation in a mindfulness training program (mindfulness-based stress reduction, [MBSR]) on the degree of bother from hot flashes and night sweats. METHODS: This study was a randomized trial of 110 late perimenopausal and early postmenopausal women experiencing an average of 5 or more moderate or severe hot flashes (including night sweats)/day. A wait-list control (WLC) was used with 3-month postintervention follow-up. The main outcome was the degree of bother from hot flashes and night sweats in the previous 24 hours. Secondary measures were hot flash intensity, quality of life, insomnia, anxiety, and perceived stress. RESULTS: Baseline average (SD) hot flash frequency was 7.87 (3.44) and 2.81 (1.76) night sweats/day. Mean (SD) bothersomeness score was 3.18 (0.55; "moderately bothered/extremely bothered"). All analyses were intention to treat and were controlled for baseline values. Within-woman changes in bother from hot flashes differed significantly by treatment arm (week × treatment arm interaction, P = 0.042). At completion of the intervention, bother in the MBSR arm decreased on average by 14.77% versus 6.79% for WLC. At 20 weeks, total reduction in bother for MBSR was 21.62% and 10.50% for WLC. Baseline-adjusted changes in hot flash intensity did not differ between treatment arms (week × treatment arm interaction, P = 0.692). The MBSR arm made clinically significant improvements in quality of life (P = 0.022), subjective sleep quality (P = 0.009), anxiety (P = 0.005), and perceived stress (P = 0.001). Improvements were maintained 3 months postintervention. CONCLUSIONS: Our data suggest that MBSR may be a clinically significant resource in reducing the degree of bother and distress women experience from hot flashes and night sweats.

RESUMEN

Therapeutic interventions that incorporate training in mindfulness meditation have become increasingly popular, but to date little is known about neural mechanisms associated with these interventions. Mindfulness-Based Stress Reduction (MBSR), one of the most widely used mindfulness training programs, has been reported to produce positive effects on psychological well-being and to ameliorate symptoms of a number of disorders. Here, we report a controlled longitudinal study to investigate pre-post changes in brain gray matter concentration attributable to participation in an MBSR program. Anatomical magnetic resonance (MR) images from 16 healthy, meditation-naïve participants were obtained before and after they underwent the 8-week program. Changes in gray matter concentration were investigated using voxel-based morphometry, and compared with a waiting list control group of 17 individuals. Analyses in a priori regions of interest confirmed increases in gray matter concentration within the left hippocampus. Whole brain analyses identified increases in the posterior cingulate cortex, the temporo-parietal junction, and the cerebellum in the MBSR group compared with the controls. The results suggest that participation in MBSR is associated with changes in gray matter concentration in brain regions involved in learning and memory processes, emotion regulation, self-referential processing, and perspective taking.
