ABSTRACT

Importance: Although psychological distress is common among survivors of critical illness, there are few tailored therapies. Objective: To determine the optimal method for delivering a mindfulness intervention via a mobile app for critical illness survivors. Design, Setting, and Participants: This randomized clinical trial used a 2 × 2 × 2 factorial design and was conducted at 3 sites among survivors of critical illness with elevated postdischarge symptoms of depression. The study was conducted between August 2019 and July 2023. Interventions: Participants were randomized to 1 of 8 different groups as determined by 3 two-level intervention component combinations: intervention introduction method (mobile app vs therapist call), mindfulness meditation dose (once daily vs twice daily), and management of increasing symptoms (mobile app vs therapist call). Main Outcomes and Measures: The primary outcome was the 9-item Patient Health Questionnaire (PHQ-9) depression scale score (range, 0-27) at 1 month. Secondary outcomes included anxiety (7-item Generalized Anxiety Disorder) and posttraumatic stress disorder (Posttraumatic Stress Scale) symptoms at 1 and 3 months, adherence, and feasibility. General linear models were used to compare main effects and interactions of the components among intervention groups. A formal decisional framework was used to determine an optimized intervention version. Results: A total of 247 participants (mean [SD] age, 50.2 [15.4] years; 104 [42.1%] women) were randomized. Twice-daily meditation compared with once-daily meditation was associated with a 1.2 (95% CI, 0.04-2.4)-unit lower mean estimated PHQ-9 score at 1 month and a 1.5 (95% CI, 0.1-2.8)-unit lower estimated mean score at 3 months. The other 2 intervention components had no main effects on the PHQ-9. Across-group adherence was high (217 participants [87.9%] using the intervention at trial conclusion) and retention was strong (191 [77.3%] and 182 [73.7%] at 1 and 3 months, respectively). Conclusions and Relevance: A mindfulness intervention for survivors of critical illness that included an app-based introduction, twice-daily guided meditation, and app-based management of increasing depression symptoms was optimal considering effects on psychological distress symptoms, adherence, and feasibility. Trial Registration: ClinicalTrials.gov Identifier: NCT04038567.

ABSTRACT

Higher trait mindfulness may be associated with better cognitive functioning and academic achievement in college students. Although mediating mechanisms are unclear, lower stress levels could explain this relationship. Participants: Cross-sectional online survey (n = 534; 33% non-white; Apr 2018 - Sep 2019). Path analysis tested Perceived Stress as a mediator between specific facets of trait mindfulness and three measures of self-reported cognitive functioning and academic achievement: Cognitive Abilities, Cognitive Concerns, and GPA. Perceived Stress fully or partially mediated the relationship between all facets of trait mindfulness and perceived cognitive functioning. Only Decentering, however, was associated with higher GPA as a function of lower stress. Lower stress can explain the link between higher trait mindfulness and better cognitive functioning, but not necessarily academic achievement. Future research is needed to address causality, examine objective measures of cognitive functioning, and extend this explanatory model to mindfulness training.

ABSTRACT

Background: Although meditation and yoga have been associated with higher trait mindfulness in general, they may help practitioners cultivate different qualities of mindfulness that manifest in different trait mindfulness profile scores. Primary Study Objective: This study tested the hypothesis that college students who practice both meditation and yoga report the highest overall trait mindfulness scores and also explored the possibility that scores on specific facets of mindfulness may differ as a function of the meditation or yoga experience. Methods/Design: The study used a cross-sectional online survey (n = 529). Analysis of covariance (ANCOVA) controlling for gender was used to compare students with neither meditation nor yoga experience, only meditation experience, only yoga experience, and both meditation and yoga experience, in terms of overall trait mindfulness (CAMS-R), five specific facets of trait mindfulness (FFMQ), decentering, and self-compassion. An exploratory analysis was also conducted to assess the construct validity of the FFMQ as a function of the meditation/yoga experience. Setting: Public university in Mid-Atlantic U.S. Participants: An undergraduate student convenience sample (age: 18-56 years; gender: 66% F; ethnicity: 32% racial minority). Results: There were no significant effects of the meditation/yoga experience on any outcome measure. Pairwise comparisons show that non-reactivity was significantly higher in the practitioners of both meditation and yoga compared to non-practitioners (P = .046, d = .026). Overall trait mindfulness was significantly higher in practitioners of both, compared to meditators only (P = .045, d = .064). Reliability and convergent validity of the FFMQ-SF were generally worse in non-practitioners. Conclusion: Testing for differences in trait mindfulness using the FFMQ-SF may not be reliable or valid in college students, particularly when students have little meditation or yoga experience. Future research with this population should utilize the long form of the FFMQ, collect additional data about participants' meditation and yoga practice, and strongly consider using multiple methods to assess mindfulness.

ABSTRACT

Objective: Trait mindfulness is associated with well-being in college students, yet it is unclear whether these associations are consistent across demographics. Participants: Undergraduate students (n = 534; 33% nonwhite; Apr2018-Sep2019). Methods: A cross-sectional online survey was performed. Pearson correlations tested the relationship between specific facets of trait mindfulness and four domains of mind-body health: stress, well-being, cognitive functioning, and health behaviors. Gender, race, and ethnicity were tested as moderators. Results: In general, higher trait mindfulness is consistently associated with better mind-body health across demographics. However, in men, some health behavior variables correlated more strongly with mindfulness. Among Black students, the relationship between Non-Reactivity and some outcome variables was null or counterintuitive. In Asian students, several predicted associations were significantly stronger. Conclusion: Trait mindfulness corresponds to mind-body health in college students, but relationships may not be universal. Future research is needed to replicate these findings and to examine possible demographic differences in response to mindfulness training.

ABSTRACT

Objective: The purpose of this systematic review was to assess the current literature on mindfulness-based school interventions (MBSIs) by evaluating evidence across specific outcomes for youth. Methods: We evaluated 77 studies with a total sample of 12,358 students across five continents, assessing the quality of each study through a robust coding system for evidence-based guidelines. Coders rated each study numerically per study design as 1++ (RCT with a very low risk of bias) to 4 (expert opinion) and across studies for the corresponding evidence letter grade, from highest quality ('A Grade') to lowest quality ('D Grade') evidence. Results: The highest quality evidence ('A Grade') across outcomes indicated that MBSIs increased prosocial behavior, resilience, executive function, attention and mindfulness, and decreased anxiety, attention problems/ADHD behaviors and conduct behaviors. The highest quality evidence for well-being was split, with some studies showing increased well-being and some showing no improvements. The highest quality evidence suggests MBSIs have a null effect on depression symptoms. Conclusion: This review demonstrates the promise of incorporating mindfulness interventions in school settings for improving certain youth outcomes. We urge researchers interested in MBSIs to study their effectiveness using more rigorous designs (e.g., RCTs with active control groups, multi-method outcome assessment, and follow-up evaluation), to minimize bias and promote higher quality-not just increased quantity-evidence that can be relied upon to guide school-based practice.

ABSTRACT

Objectives: The mindfulness stress buffering account posits mindfulness may benefit physical health by reducing stress. Previous research supports this account and suggests the non-judging facet of mindfulness may be most strongly associated with physical symptoms of stress, via lower perceived stress. The current replication study used structural equation modeling to analyze relationships between multiple facets of mindfulness, perceived stress, and physical symptoms of stress. Methods: Undergraduate students (n = 534, 68% White, 65% female) completed surveys measuring trait mindfulness (Five Facet Mindfulness Questionnaire-Short Form), perceived stress (Perceived Stress Scale), and physical symptoms of stress (Cohen-Hoberman Inventory of Physical Symptoms). Results: As hypothesized, results showed the negative relationship between four facets of mindfulness (describing, non-judging, non-reactivity, and acting with awareness) and physical symptoms of stress was partially mediated by lower perceived stress. Observing, however, was associated with more physical symptoms of stress. Conclusions: The current findings successfully replicated the results of two previous studies in an independent sample, using a more parsimonious analytic strategy that included all variables in a single path model. Results confirm the stress-buffering effect of trait mindfulness, particularly non-judging. Future research may test whether changes in trait mindfulness, particularly non-judging, explain individual differences in objective measures of stress and physical health.

ABSTRACT

OBJECTIVE: Mindfulness stress buffering theory (Creswell & Lindsay, 2014) posits higher dispositional (trait) mindfulness can protect cardiovascular health by buffering physiological stress reactivity - a risk marker for hypertension and cardiac events. Yet, empirical evidence is mixed. This study used baseline data from the Serenity Study - a recently completed, two-site randomized clinical trial - to assess the link between trait mindfulness and cardiovascular stress reactivity in adults with unmedicated prehypertension (n=153, Mage=50, 47% male, 69% White, 28% African-American). METHODS: Latent growth curve modeling was used to determine whether specific facets of trait mindfulness, measured by the Five Facet Mindfulness Questionnaire and the Decentering subscale of the Experiences Questionnaire, predict blood pressure (BP) and heart rate (HR) responses to a brief laboratory stressor (5-min anger recall task). BP and HR taken 1-min apart were used in latent growth curve models. We hypothesized after controlling for known covariates of cardiovascular health, higher trait mindfulness would predict lower cardiovascular reactivity to, and faster recovery from, acute emotional stress. RESULTS: Contrary to predictions, no mindfulness facets predicted cardiovascular reactivity or recovery. CONCLUSIONS: These findings indicate trait mindfulness facets may not independently affect BP and HR responses to acute emotional stress among prehypertensive but otherwise healthy adults with normal stress levels, prior to mindfulness training. Mindfulness-based interventions may therefore be necessary to engender benefits of mindfulness on stress physiology, as a putative biological mechanism of cardiovascular risk reduction and health promotion. Trial registration number and date of registration: NCT02371317, 1/21/2015.

ABSTRACT

Although mindfulness-based stress reduction (MBSR) can improve health and well-being, less is known about factors that predict outcomes. This prospective observational study examined gender and baseline anxiety and sleep quality as predictors of change in emotion regulation and stress symptoms following an 8-week MBSR program. Women and men reported similar improvement in stress symptoms and cognitive reappraisal, whereas men improved more in emotion suppression. Individuals with higher anxiety and worse sleep pre-treatment benefited most in terms of decreased stress. Evaluating pre-treatment characteristics could help determine optimal candidates for MBSR training, and could optimize outcomes for both women and men.

ABSTRACT

INTRODUCTION: Although as many as 75% of the >2 million annual intensive care unit (ICU) survivors experience symptoms of psychological distress that persist for months to years, few therapies exist that target their symptoms and accommodate their unique needs. In response, we developed LIFT, a mobile app-based mindfulness intervention. LIFT reduced distress symptoms more than either a telephone-based mindfulness program or education control in a pilot randomized clinical trial (LIFT1). OBJECTIVE: To describe the methods of a factorial experimental clinical trial (LIFT2) being conducted to aid in the development and implementation of the version of the LIFT intervention that is optimized across domains of effect, feasibility, scalability, and costs. METHODS AND ANALYSIS: The LIFT2 study is an optimization trial conceptualized as a component of a larger multiphase optimization strategy (MOST) project. The goal of LIFT2 is to use a 2 × 2 × 2 factorial experimental trial involving 152 patients to determine the ideal components of the LIFT mobile mindfulness program for ICU survivors across factors including (1) study introduction by call from a therapist vs. app only, (2) response to persistent or worsening symptoms over time by therapist vs. app only, and (3) high dose vs. low dose. The primary trial outcome is change in depression symptoms 1 month from randomization measured by the PHQ-9 instrument. Secondary outcomes include anxiety, post-traumatic stress disorder, and physical symptoms; measures of feasibility, acceptability, and usability; as well as themes assessed through qualitative analysis of semi-structured interviews with study participants conducted after follow up completion. We will use general linear models to compare outcomes across the main effects and interactions of the factors.

ABSTRACT

BACKGROUND: Health coaching promotes healthy lifestyles and may be particularly helpful for employees with chronic disease. OBJECTIVE: Evaluate the effects of a health coaching program that targeted health-system employees with at least one cardiovascular disease (CVD) risk factor. METHODS: Fifty-four employees volunteered for a health coaching program (6-session, 12-week program, at least one cycle). 40 (74%) completed (mean age [SD] = 53.3 [10.3] years, Female = 95%, Caucasian = 83%). A certified and integrative health coach/nutritionist provided coaching. Self-reported outcomes were collected using a pre-post design. RESULTS: Participants reported high rates of obesity (75%), hypertension (52.5%), diabetes/prediabetes (47.5%), and hyperlipidemia (40%). In addition, 20% reported chronic pain/rehabilitation needs, 17.5% seasonal depression, and 30% other significant co-morbidities. Following coaching, participants reported significant weight loss (mean [SD] 7.2 [6.6] pounds, p < 0.0001, d = 1.11), increased exercise (from 0.8 to 2.3 sessions/week, p < 0.001, d = .89), reduced perceived stress (p < 0.04, d = .42), and a trend for improved sleep (p = 0.06, d = .38). Reduced stress correlated with both increased exercise (r = -.39, p < 0.05) and decreased fatigue (r = .36, p = 0.07). CONCLUSION: Health coaching for healthcare employees with obesity and other CVD risk factors is a promising approach to losing weight, reducing stress, making healthy lifestyle changes, and improving health and well-being.

ABSTRACT

Many of today's most common, chronic, and costly diseases-from high blood pressure, to chronic pain-are related to stress. Mindfulness, considered a state, a trait, and a training, might help treat or prevent stress-related physical symptoms. A concise review of current scientific evidence shows that both higher levels of trait mindfulness as well as mindfulness training are associated with better psychological well-being, coping, and quality of life. Effects on objective measures of disease, however, are often non-significant or await replication. Larger trials with active control groups, clear diagnostic criteria, objective outcome measures, and longer-term follow-up are needed to generate better quality evidence. Yet, many studies do support integrating mindfulness into health care as part of self-care and disease management.

ABSTRACT

BACKGROUND: Patients who are sick enough to be admitted to an intensive care unit (ICU) commonly experience symptoms of psychological distress after discharge, yet few effective therapies have been applied to meet their needs. METHODS: Pilot randomised clinical trial with 3-month follow-up conducted at two academic medical centres. Adult (≥18 years) ICU patients treated for cardiorespiratory failure were randomised after discharge home to 1 of 3 month-long interventions: a self-directed mobile app-based mindfulness programme; a therapist-led telephone-based mindfulness programme; or a web-based critical illness education programme. RESULTS: Among 80 patients allocated to mobile mindfulness (n=31), telephone mindfulness (n=31) or education (n=18), 66 (83%) completed the study. For the primary outcomes, target benchmarks were exceeded by observed rates for all participants for feasibility (consent 74%, randomisation 91%, retention 83%), acceptability (mean Client Satisfaction Questionnaire 27.6 (SD 3.8)) and usability (mean Systems Usability Score 89.1 (SD 11.5)). For secondary outcomes, mean values (and 95% CIs) reflected clinically significant group-based changes on the Patient Health Questionnaire depression scale (mobile (-4.8 (-6.6, -2.9)), telephone (-3.9 (-5.6, -2.2)), education (-3.0 (-5.3, 0.8)); the Generalized Anxiety Disorder scale (mobile -2.1 (-3.7, -0.5), telephone -1.6 (-3.0, -0.1), education -0.6 (-2.5, 1.3)); the Post-Traumatic Stress Scale (mobile -2.6 (-6.3, 1.2), telephone -2.2 (-5.6, 1.2), education -3.5 (-8.0, 1.0)); and the Patient Health Questionnaire physical symptom scale (mobile -5.3 (-7.0, -3.7), telephone -3.7 (-5.2, 2.2), education -4.8 (-6.8, 2.7)). CONCLUSIONS: Among ICU patients, a mobile mindfulness app initiated after hospital discharge demonstrated evidence of feasibility, acceptability and usability and had a similar impact on psychological distress and physical symptoms as a therapist-led programme. A larger trial is warranted to formally test the efficacy of this approach. TRIAL REGISTRATION NUMBER: Results, NCT02701361.

ABSTRACT

Mindfulness-Based Stress Reduction (MBSR) is an 8-week meditation program known to improve anxiety, depression, and psychological well-being. Other health-related effects, such as sleep quality, are less well established, as are the psychological processes associated with therapeutic change. This prospective, observational study (n = 213) aimed to determine whether perseverative cognition, indicated by rumination and intrusive thoughts, and emotion regulation, measured by avoidance, thought suppression, emotion suppression, and cognitive reappraisal, partly accounted for the hypothesized relationship between changes in mindfulness and two health-related outcomes: sleep quality and stress-related physical symptoms. As expected, increased mindfulness following the MBSR program was directly correlated with decreased sleep disturbance (r = -0.21, p = 0.004) and decreased stress-related physical symptoms (r = -0.38, p < 0.001). Partial correlations revealed that pre-post changes in rumination, unwanted intrusive thoughts, thought suppression, experiential avoidance, emotion suppression, and cognitive reappraisal each uniquely accounted for up to 32% of the correlation between the change in mindfulness and change in sleep disturbance and up to 30% of the correlation between the change in mindfulness and change in stress-related physical symptoms. Results suggest that the stress-reducing effects of MBSR are due, in part, to improvements in perseverative cognition and emotion regulation, two "transdiagnostic" mental processes that cut across stress-related disorders.

ABSTRACT

OBJECTIVES: Mindfulness-based stress reduction (MBSR) promotes numerous psychological benefits, but few studies have identified for whom MBSR is most effective. The current study tested the hypothesis that lower baseline mindfulness invites more "room to grow" and, thus, predicts greater improvement during MBSR. METHOD: We examined three facets of mindfulness (awareness, acceptance, decentering) among 131 MBSR participants prior to enrollment, to test the hypothesis that lower baseline mindfulness predicts greater improvements in perceived stress, positive affect (PA), and negative affect (NA) following MBSR. RESULTS: Lower acceptance and decentering predicted greater decreases in perceived stress. Higher awareness, acceptance, and decentering predicted greater increases in PA. Higher awareness predicted greater reductions in NA. Lower decentering predicted greater reductions in NA. CONCLUSION: Findings partly supported the hypothesis that lower baseline mindfulness predicts greater improvement following MBSR and emphasize the importance of assessing multiple mindfulness facets given their unique, contrasting relations to outcomes.

ABSTRACT

OBJECTIVE AND METHODS: Research supports relationships between stress and gastrointestinal (GI) symptoms and disorders. This pilot study assesses relationships between perceived stress, quality of life (QOL), and self-reported pain ratings as an indicator of symptom management in patients who self-reported gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD). RESULTS: In the full sample (n = 402) perceived stress positively correlated with depression (r = 0.76, P < .0001), fatigue (r = 0.38, P < .0001), sleep disturbance (r = 0.40, P < .0001), average pain (r = 0.26, P < .0001), and worst pain (r = 0.25, P < .0001). Higher perceived stress also correlated with lower mental health-related QOL. Similar correlations were found for the participants with GERD (n = 188), IBS (n = 132), and IBD (n = 82). Finally, there were significant correlations in the GERD cohort between perceived stress, and average pain (r = 0.34, P < .0001) and worst pain (r = 0.29, P < .0001), and in the IBD cohort between perceived stress, and average pain (r = 0.32, P < .0001), and worst pain (r = 0.35, P < .01). CONCLUSIONS: Perceived stress broadly correlated with QOL characteristics in patients with GERD, IBS, and IBD, and their overall QOL was significantly lower than the general population. Perceived stress also appeared to be an indicator of symptom management (self-reported pain ratings) in GERD and IBD, but not IBS. While future research using objective measures of stress and symptom/disease management is needed to confirm these associations, as well as to evaluate the ability of stress reduction interventions to improve perceived stress, QOL and disease management in these GI disorders, integrative medicine treatment programs would be most beneficial to study.

ABSTRACT

Both dispositional mindfulness and mindfulness training may help to uncouple the degree to which distress is experienced in response to aversive internal experience and external events. Because emotional reactivity is a transdiagnostic process implicated in numerous psychological disorders, dispositional mindfulness and mindfulness training could exert mental health benefits, in part, by buffering emotional reactivity. The present studies examine whether dispositional mindfulness moderates two understudied processes in stress reactivity research: the degree of concordance between subjective and physiological reactivity to a laboratory stressor (Study 1); and the degree of dysphoric mood reactivity to lapses in executive functioning in daily life (Study 2). In both studies, lower emotional reactivity to aversive experiences was observed among individuals scoring higher in mindfulness, particularly non-judging, relative to those scoring lower in mindfulness. These findings support the hypothesis that higher dispositional mindfulness fosters lower emotional reactivity. Results are discussed in terms of implications for applying mindfulness-based interventions to a range of psychological disorders in which people have difficulty regulating emotional reactions to stress.

ABSTRACT

BACKGROUND: This study investigated whether the selective serotonin reuptake inhibitor (SSRI) citalopram downregulates the expression of the human immunodeficiency virus (HIV) receptor cluster of differentiation 4 (CD4) and coreceptors chemokine receptor type 5 and chemokine-related receptor type 4 (CCR5 and CXCR4) on peripheral blood mononuclear cells (PBMCs) and macrophages ex vivo as a potential mechanism of reducing susceptibility to HIV infection. METHODS: The sample included 150 participants 18-58 years old (59% women, 65% African American, 61% with depression). Monocyte-depleted PBMCs were treated with phytohemagglutinin for 72 hours and then cultured in the presence of interleukin-2 with vehicle control or the SSRI (10(-6) mol/L) for 2 hours. To generate monocyte-derived macrophages, monocytes were cultured for 7 days, after which either vehicle control or SSRI (10(-6) mol/L) was added for 2 hours. RNA was collected from both cell types, and messenger RNA expression of CD4, CCR5, and CXCR4 was measured by real-time polymerase chain reaction. RESULTS: In PBMCs, SSRI treatment decreased expression of CD4 (p = .009), CCR5 (p = .008), and CXCR4 (p < .0001). In monocyte-derived macrophages, SSRI treatment decreased expression of CD4 (p < .0001) and CXCR4 (p = .0003), but not CCR5 (p = .71). The suppressive effects of the SSRI on receptor expression did not differ as a function of depression diagnosis or depressive symptom severity. CONCLUSIONS: Treatment with the SSRI at a physiologic dose decreased CD4, CCR5, and CXCR4 expression on PBMCs and macrophages ex vivo. These findings suggest that SSRI treatment, independent of depression status, downregulates HIV receptor and coreceptor expression and may reduce susceptibility of immune cells to HIV infection and decrease inflammation. If clinical trials confirm the present findings, ultimately there may be a role for using SSRI treatment adjunctively in HIV and acquired immunodeficiency syndrome.

ABSTRACT

OBJECTIVE: Despite the well-known stress of medical school, including adverse consequences for mental and behavioral health, there is little consensus about how to best intervene in a way that accommodates students׳ intense training demands, interest in science, and desire to avoid being stigmatized. The objective of this study, therefore, was to evaluate the feasibility, acceptability, and initial effectiveness of an adapted, four-week stress management and self-care workshop for medical students, which was based on the science and practice of mind-body medicine. METHODS: The current study used a prospective, observational, and mixed methods design, with pretest and posttest evaluations. Participants (n = 44) included medical and physician-scientist (MD/PhD) students from a large, southeastern medical school. Feasibility was assessed by rates of workshop enrollment and completion. Acceptability was assessed using qualitative ratings and open-ended responses that queried perceived value of the workshop. Quantitative outcomes included students׳ ratings of stress and mindfulness using validated self-report surveys. RESULTS: Enrollment progressively increased from 6 to 15 to 23 students per workshop in 2007, 2009, and 2011, respectively. Of the 44 enrolled students, 36 (82%) completed the workshop, indicating that the four-session extracurricular format was feasible for most students. Students reported that the workshop was acceptable, stating that it helped them cope more skillfully with the stress and emotional challenges of medical school, and helped increase self-care behaviors, such as exercise, sleep, and engaging in social support. Students also reported a 32% decrease in perceived stress (P < .001; d = 1.38) and a 16% increase in mindfulness (P < .001; d = 0.92) following the workshop. Changes in stress and mindfulness were significantly correlated (r = -0.42; P = .01). CONCLUSION: Together, these findings suggest that a brief, voluntary mind-body skills workshop specifically adapted for medical students is feasible, acceptable, and effective for reducing stress, increasing mindfulness, and enhancing student self-care.

ABSTRACT

OBJECTIVE: Mindfulness-based stress reduction (MBSR) is a secular meditation training program that reduces depressive symptoms. Little is known, however, about the degree to which a participant's spiritual and religious background, or other demographic characteristics associated with risk for depression, may affect the effectiveness of MBSR. Therefore, this study tested whether individual differences in religiosity, spirituality, motivation for spiritual growth, trait mindfulness, sex, and age affect MBSR effectiveness. METHODS: As part of an open trial, multiple regression was used to analyze variation in depressive symptom outcomes among 322 adults who enrolled in an 8-week, community-based MBSR program. RESULTS: As hypothesized, depressive symptom severity decreased significantly in the full study sample (d=0.57; p<0.01). After adjustment for baseline symptom severity, moderation analyses revealed no significant differences in the change in depressive symptoms following MBSR as a function of spirituality, religiosity, trait mindfulness, or demographic variables. Paired t tests found consistent, statistically significant (p<0.01) reductions in depressive symptoms across all subgroups by religious affiliation, intention for spiritual growth, sex, and baseline symptom severity. After adjustment for baseline symptom scores, age, sex, and religious affiliation, a significant proportion of variance in post-MBSR depressive symptoms was uniquely explained by changes in both spirituality (ß=-0.15; p=0.006) and mindfulness (ß=-0.17; p<0.001). CONCLUSIONS: These findings suggest that MBSR, a secular meditation training program, is associated with improved depressive symptoms regardless of affiliation with a religion, sense of spirituality, trait level of mindfulness before MBSR training, sex, or age. Increases in both mindfulness and daily spiritual experiences uniquely explained improvement in depressive symptoms.

ABSTRACT

The purpose of this study was to test the feasibility and effectiveness of an adapted 8-week Mindfulness-Based Stress Reduction (MBSR) program for elders in a continuing care community. This mixed-methods study used both quantitative and qualitative measures. A randomized waitlist control design was used for the quantitative aspect of the study. Thirty-nine elderly were randomized to MBSR (n = 20) or a waitlist control group (n = 19), mean age was 82 years. Both groups completed pre-post measures of health-related quality of life, acceptance and psychological flexibility, facets of mindfulness, self-compassion, and psychological distress. A subset of MBSR participants completed qualitative interviews. MBSR participants showed significantly greater improvement in acceptance and psychological flexibility and in role limitations due to physical health. In the qualitative interviews, MBSR participants reported increased awareness, less judgment, and greater self-compassion. Study results demonstrate the feasibility and potential effectiveness of an adapted MBSR program in promoting mind-body health for elders.
