Exploration of a cultural-adaptation of the EQ-5D for Thai population: A "bolt-on" experiment.

PURPOSE: As the EQ-5D was developed in western countries with only five dimensions, it might be insensitive to non-western populations including Thai. This study examined the impact of adding two candidate dimensions, "interpersonal relationships (IR)" and "activities related to bending knees (AK)," to the EQ-5D questionnaire, and evaluated their psychometric properties in a Thai population sample. METHODS: Face-to-face interviews were conducted with 600 Thai. Ceiling effect for the EQ-5D and the EQ-5D-5L+AK+IR were compared. Spearman's rho correlation was used to determine whether the two new dimensions were redundant with the existing EQ-5D dimensions. Correlations between the two dimensions and similar dimensions of the SF-36v2 were also assessed. Hierarchical multiple regression was performed to evaluate the incremental value of the EQ-5D-5L+AK+IR over the EQ-5D in predicting VAS scores. RESULTS: The two new dimensions were not redundant with the existing five dimensions of the EQ-5D. The highest correlation (0.371) was found between MO and AK. The overall ceiling effect decreased by 5% (50.5-45.5%) when using the EQ-5D-5L+AK+IR. Moderate correlations were found between the candidate dimensions and similar dimensions of the SF-36v2. Multiple regression indicated that adding AK (adjusted r2 0.329 vs. 0.306) but not IR (adjusted r2 0.307 vs. 0.306) significantly increased ability to predict VAS scores. CONCLUSIONS: Our preliminary results suggested that AK holds promise for making the EQ-5D more relevant to Thai while it is premature to conclude on the impact of IR. Nevertheless, more work is required to carefully assess the value of the new dimensions as well as the trade-off for the modification.

Adding two culture-specific 'bolt-on' dimensions on the Thai version of EQ-5D-5L: an exploratory study in patients with diabetes.

BACKGROUND: This study explored whether addition of culture-specific bolt-on dimensions, 'interpersonal relationships (IR)' and 'activities related to bending knees (AK)' improves the relevance and validity of the EQ-5D among Thai patients with diabetes. METHODS: A cross-sectional study was conducted among 200 diabetic patients. Ceiling/floor effects, known-groups validity and test-retest reliability were evaluated. Hierarchical multiple regressions was performed to evaluate the incremental value of the EQ-5D+AK+IR over the EQ-5D-5L in predicting utility measured by visual analog scale (VAS). RESULTS: The EQ-5D+AK+IR reduced ceiling effects by 34%. For known-groups validity, women and lower educated patients reported more AK problems (p-value< 0.05); however, none of the IR dimension hypotheses were supported. Both IR and AK had the weighted kappa coefficients of 0.49, indicating good reliability. Hierarchical multiple regression found that adding AK (adjusted r2: 0.182 vs 0.156), but not IR (adjusted r2: 0.157 vs 0.156) significantly increased the explained variance in VAS score. CONCLUSION: Preliminary findings suggest that AK, but not IR, may be a useful addition to the EQ-5D questionnaire for use with Thai patients. Further studies in diverse populations are needed to examine the impacts of the proposed new dimensions and determine if these cultural adaptations are justified.

Reiki for Pain During Hemodialysis: A Feasibility and Instrument Evaluation Study.

PURPOSE: Pain is a problem for individuals undergoing hemodialysis. Renal disease, comorbidities, concurrent symptoms, and dialysis procedures pose barriers to adequate pain management. The purpose of this study was to evaluate feasibility, examine construct validity of The Patient-Reported Outcomes Measurement Information System (PROMIS) computerized adaptive testing (CAT) instruments, and explore pain benefits of Reiki sessions conducted during hemodialysis. DESIGN: A one group, repeated-measures design was used. METHOD: Fifteen participants received Reiki for 20 minutes, twice a week for 4 weeks. Pain, fatigue, and depression were evaluated using established symptom scales and PROMIS CAT instruments. FINDINGS: Participants reported general relaxation feelings with Reiki and acceptability of using a touch-screen device to respond to web-based measures. Although staff were initially reluctant to engage patients for Reiki, they reported Reiki did not interfere with workflow and thought Reiki could be integrated into the practice setting. Significant, strong correlations with established symptom scales support construct validity of PROMIS CAT instruments. There was a significant decrease in mean symptom scores after four weeks of Reiki. Effect size values suggest a range of practical significance. CONCLUSIONS: Findings suggest Reiki provides symptom relief for individuals receiving hemodialysis, and randomized clinical trials to establish Reiki's pain benefits in this population are warranted.

A Holistic Clustering Methodology for Liver Transplantation Survival.

BACKGROUND: Liver transplants account for a high number of procedures with major investments from all stakeholders involved; however, limited studies address liver transplant population heterogeneity pretransplant predictive of posttransplant survival. OBJECTIVE: The aim of the study was to identify novel and meaningful patient clusters predictive of mortality that explains the heterogeneity of liver transplant population, taking a holistic approach. METHODS: A retrospective cohort study of 344 adult patients who underwent liver transplantation between 2008 through 2014. Predictors were summarized severity scores for comorbidities and other suboptimal health states grouped into 11 body systems, the primary reason for transplantation, demographics/environmental factors, and Model for End Liver Disease score. Logistic regression was used to compute the severity scores, hierarchical clustering with weighted Euclidean distance for clustering, Lasso-penalized regression for characterizing the clusters, and Kaplan-Meier analysis to compare survival across the clusters. RESULTS: Cluster 1 included patients with more severe circulatory problems. Cluster 2 represented older patients with more severe primary disease, whereas Cluster 3 contained healthiest patients. Clusters 4 and 5 represented patients with musculoskeletal (e.g., pain) and endocrine problems (e.g., malnutrition), respectively. There was a statistically significant difference for mortality between clusters (p < .001). CONCLUSIONS: This study developed a novel methodology to address heterogeneous and high-dimensional liver transplant population characteristics in a single study predictive of survival. A holistic approach for data modeling and additional psychosocial risk factors has the potential to address holistically nursing challenges on liver transplant care and research.

Mindfulness-based resilience training to reduce health risk, stress reactivity, and aggression among law enforcement officers: A feasibility and preliminary efficacy trial.

The primary objective of this study was to assess feasibility and gather preliminary outcome data on Mindfulness-Based Resilience Training (MBRT) for law enforcement officers. Participants (n = 61) were randomized to either an 8-week MBRT course or a no intervention control group. Self-report and physiological data were collected at baseline, post-training, and three months following intervention completion. Attendance, adherence, post-training participant feedback, and interventionist fidelity to protocol all demonstrated feasibility of MBRT for law enforcement officers. Compared to no intervention controls, MBRT participants experienced greater reductions in salivary cortisol, self-reported aggression, organizational stress, burnout, sleep disturbance, and reported increases in psychological flexibility and non-reactivity at post-training; however, group differences were not maintained at three-month follow-up. This initial randomized trial suggests MBRT is a feasible intervention. Outcome data suggest MBRT targets key physiological, psychological, and health risk factors in law enforcement officers, consistent with the potential to improve officer health and public safety. However, follow-up training or "booster" sessions may be needed to maintain training gains. A fully powered longitudinal randomized trial is warranted.

Usability and clinical efficacy of diabetes mobile applications for adults with type 2 diabetes: A systematic review.

OBJECTIVES: To assess the usability and clinical effectiveness of diabetes mobile applications (diabetes apps) developed for adults with type 2 diabetes. METHOD: A systematic review of the usability and effectiveness of diabetes apps was conducted. Searches were performed using MEDLINE, EMBASE, COMPENDEX, and IEEE XPLORE for articles published from January 1, 2011, to January 17, 2017. Search terms included: diabetes, mobile apps, and mobile health (mHealth). RESULTS: The search yielded 723 abstracts of which seven usability studies and ten clinical effectiveness studies met the inclusion criteria from 20 publications. Usability, as measured by satisfaction ratings from experts and patients, ranged from 38% to 80%. Usability problem ratings ranged from moderate to catastrophic. Top usability problems are multi-steps task, limited functionality and interaction, and difficult system navigation. Clinical effectiveness, measured by reductions in HbA1c, ranged from 0.15% to 1.9%. CONCLUSION: Despite meager satisfaction ratings and major usability problems, there is some limited evidence supporting the effectiveness of diabetes apps to improve glycemic control for adults with type 2 diabetes. Findings strongly suggest that efforts to improve user satisfaction, incorporate established principles of health behavior change, and match apps to user characteristics will increase the therapeutic impact of diabetes apps.

Telephone-adapted Mindfulness-based Stress Reduction (tMBSR) for patients awaiting kidney transplantation.

BACKGROUND: Patients with progressive kidney disease experience increasing physiologic and psychosocial stressors and declining health-related quality of life (HRQOL). METHODS: We conducted a randomized, active-controlled, open-label trial to test whether a Mindfulness-based Stress Reduction (MBSR) program delivered in a novel workshop-teleconference format would reduce symptoms and improve HRQOL in patients awaiting kidney transplantation. Sixty-three transplant candidates were randomized to one of two arms: i) telephone-adapted MBSR (tMBSR, an 8-week program of meditation and yoga); or ii) a telephone-based support group (tSupport). Participants completed self-report questionnaires at baseline, post-intervention, and after 6-months. Anxiety, measured by the State-Trait Anxiety Inventory (STAI) post-intervention served as the primary outcome. Secondary outcomes included: depression, sleep quality, pain, fatigue, and HRQOL assessed by SF-12 Physical and Mental Component Summaries (PCS, MCS). RESULTS: 55 patients (age 54±12yrs) attended their assigned program (tMBSR, n=27; tSupport, n=28). 49% of patients had elevated anxiety at baseline. Changes in anxiety were small and did not differ by treatment group post-intervention or at follow-up. However, tMBSR significantly improved mental HRQOL at follow-up: +6.2 points on the MCS - twice the minimum clinically important difference (95% CI: 1.66 to 10.8, P=0.01). A large percentage of tMBSR participants (≥90%) practiced mindfulness and reported it helpful for stress management. CONCLUSIONS: Neither mindfulness training nor a support group resulted in clinically meaningful reductions in anxiety. In contrast, finding that tMBSR was more effective than tSupport for bolstering mental HRQOL during the wait for a kidney transplant is encouraging and warrants further investigation.

Predictors of Liver Transplant Patient Survival.

OBJECTIVE: Liver transplantation is a costly and risky procedure, representing 25 050 procedures worldwide in 2013, with 6729 procedures performed in the United States in 2014. Considering the scarcity of organs and uncertainty regarding prognosis, limited studies address the variety of risk factors before transplantation that might contribute to predicting patient's survival and therefore developing better models that address a holistic view of transplant patients. This critical review aimed to identify predictors of liver transplant patient survival included in large-scale studies and assess the gap in risk factors from a holistic approach using the Wellbeing Model and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. DATA SOURCE: Search of the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, and PubMed from the 1980s to July 2014. STUDY SELECTION: Original longitudinal large-scale studies, of 500 or more subjects, published in English, Spanish, or Portuguese, which described predictors of patient survival after deceased donor liver transplantation. DATA EXTRACTION: Predictors were extracted from 26 studies that met the inclusion criteria. DATA SYNTHESIS: Each article was reviewed and predictors were categorized using a holistic framework, the Wellbeing Model (health, community, environment, relationship, purpose, and security dimensions). CONCLUSIONS: The majority (69.7%) of the predictors represented the Wellbeing Model Health dimension. There were no predictors representing the Wellbeing Dimensions for purpose and relationship nor emotional, mental, and spiritual health. This review showed that there is rigorously conducted research of predictors of liver transplant survival; however, the reported significant results were inconsistent across studies, and further research is needed to examine liver transplantation from a whole-person perspective.

Well-Being and Self-Assessment of Change: Secondary Analysis of an RCT That Demonstrated Benefit of Inhaled Lavender and Sleep Hygiene in College Students with Sleep Problems.

CONTEXT: Sleep issues are prevalent and affect health and well-being. The aspects of well-being that are impacted by sleep interventions have not been well studied. OBJECTIVES: To investigate the impact of lavender and sleep hygiene (LSH) compared to sleep hygiene (SH) alone on well-being as measured by the Self-assessment of Change questionnaire (SAC) at post-intervention and two-week follow-up, and secondarily to compare the SAC sleep item to results from standardized sleep surveys. DESIGN: Secondary analysis of a randomized controlled trial (RCT) where one group received a lavender inhalation patch and practiced sleep hygiene (LSH) and the other group received a placebo inhalation patch and practiced sleep hygiene (SH) for five consecutive nights. SETTING: Usual sleep setting. PARTICIPANTS: Seventy-nine college students with self-reported sleep issues. MAIN OUTCOME MEASURES: The SAC was completed at post-intervention and follow-up. RESULTS: Exploratory analysis showed significantly improved well-being for the LSH group at post-intervention for well-being domains of sleep, energy, and vibrancy (P = .01, .03, and .05, respectively) and an overall trend of improved well-being in comparison to the SH group at post-intervention and follow-up. The SAC sleep item showed a similar pattern of change to the standardized sleep surveys with a statistically significant improvement in sleep for the LSH group at follow-up (P = .02). CONCLUSIONS: Findings demonstrate the positive impact of the lavender intervention on three domains of self-assessed well-being are energy, vibrancy, and sleep. SAC results extend and complement prior findings of improved sleep quality.

Emotional and Financial Experiences of Kidney Donors over the Past 50 Years: The RELIVE Study.

BACKGROUND AND OBJECTIVES: Most kidney donors view their experience positively, but some may experience psychosocial and financial burdens. We hypothesized that certain donor characteristics, poor outcome of the recipient, negative perceptions of care, and lack of support may be associated with poor psychosocial outcomes for donors. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The Renal and Lung Living Donors Evaluation Study (RELIVE) examined long-term medical and psychosocial outcomes for kidney donors (at three U.S. transplant centers) who donated between 1963 and 2005. Standardized questionnaires evaluated donor perspectives, recovery time, social support, motivation, financial impact, insurability after donation, and current psychological status. Questionnaires were mailed to 6909 donors. RESULTS: Questionnaires were returned by 2455 donors, who had donated 17 ± 10 years earlier (range, 5-48 years), a response rate of 36%. Most (95%) rated their overall donation experience as good to excellent. Rating the overall donor experience more negatively was associated with donor complications, psychological difficulties, recipient graft failure, and longer time since donation. Nine percent (n=231) reported one or more of the following poor psychosocial outcomes: fair or poor overall donor experience, financial burden, regret or discomfort with decision to donate, or psychological difficulties since donation. Recipient graft failure was the only predictor for reporting one or more of these poor psychosocial outcomes (odds ratio, 1.77; 95% confidence interval, 1.33 to 2.34). Donors with lower educational attainment experienced greater financial burden. One of five employed donors took unpaid leave; 2% reported health and life insurability concerns. CONCLUSIONS: Although the majority of donors viewed their overall donation experience positively, almost 1 in 10 donors reported at least one negative consequence related to donation. Recipient graft failure was associated with poor psychosocial outcome, defined as one or more of these negative consequences. Some donors were financially disadvantaged, and some experienced insurance difficulties. Interventions to avoid negative psychosocial and financial consequences are warranted.

Telephone-adapted mindfulness-based stress reduction (tMBSR) for patients awaiting kidney transplantation: Trial design, rationale and feasibility.

BACKGROUND: Mindfulness-based stress reduction (MBSR) has demonstrated benefits for stress-related symptoms; however, for patients with burdensome treatment regimens, multiple co-morbidities and mobility impairment, time and travel requirements pose barriers to MBSR training. PURPOSE: To describe the design, rationale and feasibility results of Journeys to Wellness, a clinical trial of mindfulness training delivered in a novel workshop and teleconference format. The trial aim is to reduce symptoms and improve quality of life in people waiting for a kidney transplant. METHODS: The standard 8-week MBSR program was reconfigured for delivery as two in-person workshops separated in time by six weekly teleconferences (tMBSR). A time and attention comparison condition (tSupport) was created using the workshop-telephone format. FEASIBILITY RESULTS: Kidney transplant candidates (N = 63) were randomly assigned to tMBSR or tSupport: 87% (n = 55) attended ≥ 1 class, and for these, attendance was high (6.6 ± 1.8 tMBSR and 7.0 ± 1.4 tSupport sessions). Fidelity monitoring found that all treatment elements were delivered as planned and few technical problems occurred. Patients in both groups reported high treatment satisfaction, but more tMBSR (83%) than tSupport (43%) participants expected their intervention to be quite a bit or extremely useful for managing their health. Symptoms and quality of life outcomes collected before (baseline, 8 weeks and 6 months) and after kidney transplantation (2, 6 and 12 months) will be analyzed for efficacy. CONCLUSIONS: tMBSR is an accessible intervention that may be useful to people with a wide spectrum of health conditions. Clinicaltrials.gov: NCT01254214.

Development of an adverse-event coping scale (AECS) using item response theory.

BACKGROUND: Adverse drug events (ADEs) cause significant morbidity and mortality to patients. A brief questionnaire asking patients how they coped with such problems could be a useful tool for providing timely interventions. OBJECTIVE: The aim of this study was to develop an adverse-event coping scale (AECS) to measure patients' coping responses to their ADE. METHODS: Data were collected from subjects recruited from community pharmacies. Psychometric analyses based on item response theory (IRT) were performed to calibrate items and assess reliability. Convergent validity was evaluated by testing a priori formulated hypotheses about expected correlations between the coping scores and other related scales. RESULTS: A total of 140 patients participated in this study by answering the developed items. Confirmatory factor analysis supported a one-dimensional item bank with 11 items. The developed scale was reliable with the reliability coefficient of 0.82. Coping scores were positively correlated with seriousness of the ADE and health literacy, but not coping self-efficacy. Overall, results suggest that the score reflects problem magnitude and coping effort rather than coping efficacy. CONCLUSION: A high score on the AECS indicates an ADE serious enough to prompt a patient to invest substantial efforts to cope with it. The final AECS item bank and its short-form can help clinicians better understand their patients' ADE-coping efforts.

Healthcare utilization and costs in persons with insomnia in a managed care population.

OBJECTIVES: To better understand the direct costs of insomnia. Our study aimed to compare healthcare costs and utilization of patients diagnosed with insomnia who received care in a managed care organization with a set of matched controls. DESIGN: Our observational, retrospective cohort study compared 7647 adults with an insomnia diagnosis with an equally sized matched cohort of health plan members without an insomnia diagnosis between 2003 and 2006. We also compared a subset of patients diagnosed with and treated for insomnia with those diagnosed with insomnia but not treated. SETTING: A large Midwestern health plan with more than 600,000 members. RESULTS: Multivariate analysis was used to estimate the association between insomnia diagnosis and costs, controlling for covariates, in the baseline and follow-up periods. Although we cannot conclude a causal relationship between insomnia and healthcare costs, our analysis found that insomnia diagnosis was associated with 26% higher costs in the baseline and 46% in the 12 months after diagnosis. When comorbidities were recognized, the insomnia cohort had 80% higher costs, on average, than the matched control cohort. CONCLUSIONS: These outcomes suggest the need to look beyond the direct cost of insomnia to how its interaction with comorbid conditions drives healthcare cost and utilization.

Quality of life in elderly kidney transplant recipients.

OBJECTIVES: To evaluate quality of life (QOL) in kidney transplant recipients aged 65 and older, identify predictors of impaired physical and mental QOL cross-sectionally and compare QOL over time with that of younger transplant recipients and general population controls. DESIGN: Comparison of serial Medical Outcomes Study 36-item Short-Form Survey (SF-36) QOL scores in transplant recipients aged 65 and older with those of transplant recipients younger than 65 and with those of general population controls from the National Health Measurement Study (NHMS). SETTING: University of Minnesota. PARTICIPANTS: Individuals aged 65 and older (n = 150) and younger than 65 (n = 1,544) who received a primary kidney transplant between 1963 and 2009. MEASUREMENTS: Two-sample t-tests and logistic regression were used to assess the risk of significant impairment in physical and mental QOL, defined as 1 standard deviation below the general population norms (<40 points) for the SF-36 Physical (PCS) and Mental Component Subscale (MCS) scores. RESULTS: PCS scores were 39.3 for transplant recipients aged 65 and older, 43.5 for recipients younger than 65, and 49.2 for NHMS controls (P < .005 for each pairwise comparison). MCS scores were 54.6 for transplant recipients aged 65 and older, 51.0 for recipients younger than 65, and 53.8 for NHMS controls (P < .005 for ≥ 65 vs <65 and NHMS vs <65). These scores did not change significantly from the first (3.6 years after transplant) to the last (6.2 years after transplant) survey. Longer time since transplantation in elderly participants was associated with having significantly impaired physical QOL, but no predictors were associated with significantly impaired mental QOL. In younger recipients, rejection, diabetes mellitus, delayed graft function, coronary artery disease, and longer time on dialysis were associated with impaired physical QOL. Rejection, smoking, diabetes mellitus, and longer time on dialysis were predictors of impaired mental QOL. CONCLUSION: Physical QOL is lower in elderly recipients but mental QOL is maintained and is higher than in younger recipients.

Outcome measures of behavioral weight loss programs in perimenopause.

Obesity and being overweight are associated with many comorbid conditions and are major contributing factors to cardiovascular disease. The increased proportion of overweight and obese people in Western societies has been attributed largely to behaviors that include sedentary lifestyle and dietary excess. Women are at particular risk during perimenopause, when hormones change and metabolism slows. The purpose of this review was to examine published studies of weight loss programs for perimenopausal women using behavioral change strategies of diet alone, regular physical activity alone, or both in combination to determine the range of potential outcomes and reduction of cardiovascular risks. Based on the findings from this review, practice applications and recommendations for future research are proposed.

Satisfaction With Life Among Living Kidney Donors: A RELIVE Study of Long-Term Donor Outcomes.

BACKGROUND: Little is known about living kidney donors' satisfaction with life (SWL) after donation. We compared donors' SWL to previously reported general population samples and investigated predictors of donors' SWL. METHODS: Three transplant centers mailed questionnaires to assess SWL, physical health, optimism, retrospective evaluation of the donation experience, and demographic characteristics to living kidney donors' homes between 2010 and 2012. Two thousand four hundred fifty-five donors who were between 5 and 48 years from the time of their donor surgery completed the questionnaire. RESULTS: Eighty-four percent of donors were satisfied with their lives (scores ≥ 20 on the Satisfaction With Life Scale). Donors were at least as satisfied with their lives as previously reported general population samples. After adjusting for physical health, optimism, and demographics, donors' SWL was significantly associated with donors' recalled experience of donation. Social support and positive effects of the donation on relationships predicted greater SWL. Financial difficulties associated with donation and longer recovery times predicted lower SWL. Recipient outcomes were not significantly related to donor SWL. DISCUSSION: Limitations include the lack of predonation SWL data, potential bias in postdonation SWL because of the situational context of the questionnaire, and a sample that is not representative of all U.S. living kidney donors. Nonetheless, strategies focused on improving the donation experience, particularly related to recovery time, financial issues, and social support, may result in greater SWL after donation.

Change in Balance Confidence and Its Associations With Increasing Disability in Older Community-Dwelling Women at Risk for Falling.

OBJECTIVES: To describe change in balance confidence, and to identify associated factors and disabling consequences. METHOD: Secondary analysis of 2 years of data collected from 272 older women enrolled in a randomized clinical trial of fall prevention. Balance confidence and disability measures were assessed at baseline, after the 12 week intervention, and at 1 and 2 years follow-up. Associated factors were measured at baseline. RESULTS: Balance confidence varied at baseline and decreased 5% over 2 years, but no variables predicted this decline. Baseline balance confidence was associated with poor physical function and mental health. Decreasing balance confidence was associated with increasing impairments in balance and hip flexion strength, increasing functional limitations in mobility and chair rises, reduced physical activity levels, increased activity restrictions, and decreasing social networks. DISCUSSION: Decreasing balance confidence plays an important role in disablement. More research is needed to identify predictors of decreasing balance confidence.

How mindfulness changed my sleep: focus groups with chronic insomnia patients.

BACKGROUND: Chronic insomnia is a major public health problem affecting approximately 10% of adults. Use of meditation and yoga to develop mindful awareness ('mindfulness training') may be an effective approach to treat chronic insomnia, with sleep outcomes comparable to nightly use of prescription sedatives, but more durable and with minimal or no side effects. The purpose of this study was to understand mindfulness training as experienced by patients with chronic insomnia, and suggest procedures that may be useful in optimizing sleep benefits. METHODS: Adults (N = 18) who completed an 8-week mindfulness-based stress reduction (MBSR) program as part of a randomized, controlled clinical trial to evaluate MBSR as a treatment for chronic insomnia were invited to participate in post-trial focus groups. Two groups were held. Participants (n = 9) described how their sleep routine, thoughts and emotions were affected by MBSR and about utility (or not) of various mindfulness techniques. Groups were audio-recorded, transcribed and analyzed using content analysis. RESULTS: Four themes were identified: the impact of mindfulness on sleep and motivation to adopt a healthy sleep lifestyle; benefits of mindfulness on aspects of life beyond sleep; challenges and successes in adopting mindfulness-based practices; and the importance of group sharing and support. Participants said they were not sleeping more, but sleeping better, waking more refreshed, feeling less distressed about insomnia, and better able to cope when it occurred. Some participants experienced the course as a call to action, and for them, practicing meditation and following sleep hygiene guidelines became priorities. Motivation to sustain behavioral changes was reinforced by feeling physically better and more emotionally stable, and seeing others in the MBSR class improve. The body scan was identified as an effective tool to enable falling asleep faster. Participants described needing to continue practicing mindfulness to maintain benefits. CONCLUSIONS: First-person accounts are consistent with published trial results of positive impacts of MBSR on sleep measured by sleep diary, actigraphy, and self-report sleep scales. Findings indicate that mindfulness training in a group format, combined with sleep hygiene education, is important for effective application of MBSR as a treatment for chronic insomnia.

Mindfulness: a systematic review of instruments to measure an emergent patient-reported outcome (PRO).

PURPOSE: Mindfulness has emerged as an important health concept based on evidence that mindfulness interventions reduce symptoms and improve health-related quality of life. The objectives of this study were to systematically assess and compare the properties of instruments to measure self-reported mindfulness. METHODS: Ovid Medline(®), CINAHL(®), and PsycINFO(®) were searched through May 2012, and articles were selected if their primary purpose was development or evaluation of the measurement properties (validity, reliability, responsiveness) of a self-report mindfulness scale. Two reviewers independently evaluated the methodological quality of the selected studies using the COnsensus-based Standards for the selection of health status Measurement INstruments checklist. Discrepancies were discussed with a third reviewer and scored by consensus. Finally, a level of evidence approach was used to synthesize the results and study quality. RESULTS: Our search strategy identified a total of 2,588 articles. Forty-six articles, reporting 79 unique studies, met inclusion criteria. Ten instruments quantifying mindfulness as a unidimensional scale (n = 5) or as a set of 2-5 subscales (n = 5) were reviewed. The Mindful Attention Awareness Scale was evaluated by the most studies (n = 27) and had positive overall quality ratings for most of the psychometric properties reviewed. The Five Facet Mindfulness Questionnaire received the highest possible rating ("consistent findings in multiple studies of good methodological quality") for two properties, internal consistency and construct validation by hypothesis testing. However, none of the instruments had sufficient evidence of content validity. Comprehensiveness of construct coverage had not been assessed; qualitative methods to confirm understanding and relevance were absent. In addition, estimates of test-retest reliability, responsiveness, or measurement error to guide users in protocol development or interpretation of scores were lacking. CONCLUSIONS: Current mindfulness scales have important conceptual differences, and none can be strongly recommended based solely on superior psychometric properties. Important limitations in the field are the absence of qualitative evaluations and accepted external referents to support construct validity. Investigators need to proceed cautiously before optimizing any mindfulness intervention based on the existing scales.
