Abstract
BACKGROUND Orthopedic patients report pain as their main symptom complaint. Subjective pain experience is correlated with self-reported psychological state, such as distress. PURPOSE This study tests whether scores from a measure of mindful attention are associated with subjective pain levels and whether psychological distress scores function as a mediation path. METHODS During routine visits to a single orthopedic clinic in East Los Angeles, California, 525 patients were recruited to participate in the study. Participants reported on measures of pain (Universal Pain Assessment Tool [UPAT]), mindful attention (Five-Facet Mindfulness Questionnaire [FFMQ]), and psychological distress (Depression, Anxiety, Stress Scale [DASS]). We used Pearson correlations to examine relationships between FFMQ and UPAT scores and mediation analyses to test indirect effects of DASS scores as a mediation path. RESULTS The average age of the sample was 54 years (range 18-98 years), 61% were male, and 64% were non-Hispanic White individuals. The locations of injury were the shoulder (72%), elbow (21%), and clavicle or wrist (7%). Ninety-one percent reported mild or greater pain in the prior 2 weeks (mean = 4.2 ± 2.5, range 0-10), and 49% reported mild or more severe distress symptoms (DASS: 13.0 ± 11.5). FFMQ scores inversely predicted UPAT scores (β = -0.22, P < .01), mediated through DASS scores. DASS subscale scores for depression (β = -0.10, P = .02) and stress (β = -0.08, P = .04) but not anxiety (β = -0.03, P = .33) produced significant indirect effects. FFMQ acting-with-awareness and non-judging subscales had the largest effect on depression and stress DASS subscale scores. CONCLUSIONS We find statistical support to suggest that distress-particularly depressed mood and stress-mediates the association between mindful attention and pain intensity among orthopedic patients. A disposition of mindful attention might counter distress ailments that exacerbate subjective pain, and this has possible implications for mindfulness training interventions offered to orthopedic patients.

Abstract
BACKGROUND Cigarette smoking is the leading cause of preventable cancers. A majority of the 34 million people who currently smoke report wanting to quit. Mindfulness training apps offer a guided telehealth intervention to foster individuals' behavioral meditation practice. We present the main outcomes of a parallel-group randomized controlled trial that tested app-based mindfulness training vs attention control on smoking behavior. METHODS We enrolled adult residents from across California who smoked daily and were willing to make a quit attempt (N = 213). Participants completed daily sessions in 10-minute segments for 14 consecutive days. Participants then started a quit attempt and reported daily smoking for 28 days following the quit date using the timeline follow-back measure. RESULTS Seven-day point-prevalence abstinence for each week during the 4-week quit period ranged from 21.8% to 27.7% for app-based mindfulness training and 17.9% to 19.6% for controls. The intention-to-treat sample revealed that app-based mindfulness training outperformed controls on the proportion of abstinence days during the quit period (odds ratio = 2.00, 95% confidence interval = 1.03 to 3.87, P = .041). Although the 7-day point prevalence abstinence for week 4 favored app-based mindfulness training, significance was not reached (odds ratio = 1.65, 95% confidence interval = 0.84 to 3.23, P = .148). The mean number of cigarettes smoked per day among smokers was 4.95 for app-based mindfulness training vs 5.69 for controls (odds ratio = 0.81, 95% confidence interval = 0.71 to 0.92, P = .002), suggesting harm reduction in continued smokers. CONCLUSION A mindfulness training app prescribed for 2 weeks leading up to a quit date showed an advantage over controls for total abstinence days and fewer cigarettes smoked in a diverse sample consisting of urban and rural residents. These findings yield implications for the use of apps to reduce exposure to the carcinogenic properties of cigarette smoke.

Abstract
A majority of the 34 million people who currently smoke cigarettes report wanting to quit smoking yet most attempts to quit end in relapse. A mindfulness based intervention (MBI) is an intervention package used to reinforce an individual's practice of mindfulness meditation in daily life. MBIs delivered by phone app offer daily prompts to guide bouts of mindfulness meditation, that is, sustained attention to moment-by-moment experience without behavior reactivity. Daily bouts of mindfulness meditation offer individuals a replacement behavior for smoking during a quit attempt, and MBI app instruction aims to increase an individual's skill in non-reactivity when they experience cravings. Our study objective is to test the effect of an app-based MBI on abstinence during a scheduled quit attempt among people who currently smoke and who are willing to make a voluntary quit attempt on a selected near-term date. Our delivery of a smartphone app-based MBI occurs daily for the two weeks preceding a planned quit date. Study participants are randomized to a either a app-based MBI or an app-based psychoeducation control group and asked to self-administer their intervention two times a day in 10-min segments for 14 sequential days for a total of 280 min. This preparatory period capitalizes on time to help participants orient toward a near-term goal to quit smoking, practice mindfulness meditation, and increase the skill of non-reactivity during states of craving to smoke. We recruit people who smoke cigarettes from all 58 counties in California. We test the hypothesis that an app-based MBI will outperform a time-matched psychoeducation control on increasing smoking abstinence. Findings contribute knowledge to the addictions treatment field about whether MBIs delivered by app can increase smoking cessation in a geographically diverse sample.

Abstract
Background: Whether affective states acutely predict the hypothalamic–pituitary–adrenal (HPA) axis activities and whether energy balance-related behaviors moderate the affect–HPA axis relationship in obese youths are not well-understood. Methods: 87 mostly obese (94.3% obese) minority adolescents (mean: 16.3 ± 1.2 years old; 56.8% Latino and 43.2% African American) participated in a randomized crossover trial in an observation laboratory, where they received either high-sugar/low-fiber (HSLF) or low-sugar/high-fiber (LSHF) meals first and then crossed over in the next visit 2–4 weeks later. During each visit, they rated five affective states and provided a saliva sample every 30 min for the first 5 h and wore a waist-worn accelerometer. The association between the affect ratings and cortisol levels in the subsequent 30 min and the moderation effect of energy balance-related behavior were examined using multilevel models. Results: Within-person negative affect (β = 0.02, p = 0.0343) and feeling of panic (β = 0.007, p = 0.004) were acutely related to the subsequent cortisol level only during the HSLF condition. The time spent in moderate-to-vigorous physical activity did not moderate the acute relationship between affect and the subsequent cortisol level. Conclusions: Negative affect could be acutely related to heightened HPA axis activities in youths, but only when they were exposed to meals with high sugar and low fiber content. These results suggest that the meals’ sugar and fiber content may modulate HPA axis reactivity to negative affect in youths.

Abstract
Mindfulness-based interventions (MBIs) may offer a means for Latinx families to ameliorate stress, enhance emotion regulation, and foster social support. We assessed pilot data from Latinx parents in Eastside Los Angeles (n = 27) matched with their children aged 10-16 (n = 32) to determine whether participation in a community-derived MBI was associated with greater improvements in dispositional mindfulness, perceived stress, emotion regulation, and family social support compared to a control condition. Compared to the control group, parents in the MBI group showed greater reductions in perceived stress scale (PSS) scores (B = - 2.94, 95% CI [- 5.58, - 0.39], p = 0.029), while their children reported greater increases in perceived social support from family (B = 2.32, 95% CI [0.26, 4.38], p = 0.027). Findings show a community-derived MBI may improve stress in Latinx parents and social support for their children.

Abstract
OBJECTIVE To examine the association of perceived distress tolerance-one's ability to endure aversive experiences-with subsequent substance use frequency during adolescence. METHODS High school students (N = 3,203) were surveyed semiannually from 2013 to 2017. The Distress Tolerance Scale (DTS) was administered at baseline (9th grade) and self-reported past 30-day number of days used of alcohol, cigarettes, e-cigarettes, cannabis, and opioids (range: 0-30) were assessed at all timepoints. Self-reported baseline ever (vs. never) use of each substance and depressive/anxiety symptom status (clinical and subclinical vs. none) were tested as moderators. RESULTS Among baseline never substance users, a greater baseline mean DTS score was associated with fewer days of alcohol, cigarette, and opioid use in past-30 days over 4 years of follow-up (IRR range = 0.60-0.84); among ever-users, baseline mean DTS was not significantly associated with substance use across follow-up timepoints (p-interaction = 0.03). The association of DTS and frequency of substance use did not differ by baseline mental health status for any substance (all ps > 0.05). CONCLUSIONS Greater perceived distress tolerance at the start of high school may be a protective factor against substance use frequency prior to initial use. Interventions that build distress tolerance in early adolescence may be warranted to prevent higher frequency substance use throughout high school.

Abstract
Background: Telephone calls and text messages function as cues to elicit patient behavior. Objective: We tested the effect of telephone call and text message reminders on patient return to acupuncture follow-up treatment. Design: This is a randomized controlled trial. Setting and Subjects: We recruited adults visiting an acupuncture clinic for a new treatment consultation. Our sample contained 120 participants with 40 per study group. Interventions: Consenting patients were randomized to 1 of 3 study exposures: single voice call, single text message, or treatment as usual (TAU/no reminder). Exposures were sent 3 days after patient's initial treatment. Outcome Measures: Data from clinic charts were abstracted to quantify the absence/presence of a follow-up treatment return in the 30 days after initial treatment. Participants provided self-report of pain symptoms 10 and 30 days after initial treatment on the pain disability index (PDI) to measure change in PDI by return to follow-up treatment as a secondary outcome. Results: Telephone call (56%, P = 0.98) and text message (57%, P = 0.99) groups showed similar proportion of follow-up treatment returns compared with TAU group (57%). Presence of a follow-up appointment scheduled at the initial treatment predicted patient treatment return (odds ratio: 5.87, P < 0.01). Follow-up treatment return predicted reduced PDI scores at day 30 (β = -3.09, P = 0.02). Conclusions: Adding a 1-time telephone call or text message reminder to standard clinic practice did not improve patient return to acupuncture follow-up treatment within 30 days of initial treatment. Scheduling a future appointment date at initial treatment visit may improve treatment return, and return attendance appears protective of pain disability in the short term.

Abstract
Introduction Translational evidence for mind-body interventions in hand therapy is limited. This pilot study aimed to determine potential benefits of including a mindful body scan or sonographic biofeedback at the outset of a hand therapy session on key psychological states. Methods A randomized, repeated-measures, cross-over design was used to evaluate a mindful body scan and sonographic biofeedback at the outset of a hand therapy session. Measures of pain, anxiety, and stress (i.e., salivary cortisol) were obtained from 21 hand therapy patients at the start, after 20 minutes, and at the end of each of three 60-minute treatments. Trends were examined, and mixed-effects regression compared effects across time within and across the sessions for each of the outcome measures. Results For all intervention types, anxiety and stress decreased across the treatment session (p<0.001); no statistically significant changes were noted in pain. Using either mind-body intervention before standard care resulted in a meaningful decrease and statistical trend toward improvement in stress. The use of a mindful body scan produced an immediate, statistically significant reduction in anxiety (β = -0.14, p = 0.03), a lowered level that was maintained throughout the therapy session. Discussion These data provide preliminary support for integrating mind-body interventions as preparatory activities in hand therapy. Mindful body scans may prepare patients for therapeutic interventions by more quickly reducing anxiety, and the use of either intervention may reduce patient stress more than would occur during a standard care session. These effects should be evaluated in an adequately powered clinical trial.

Abstract
Racial/ethnic and sexual minorities may experience excess stress from social prejudice and structural disadvantage, which is associated with family relationship problems and poorer psychosocial health. There is increasing evidence that certain positive psychological processes can attenuate these negative outcomes at the individual and interpersonal levels; however, the mechanisms of these effects remain poorly understood. Based on previous research and two extant conceptual frameworks, we constructed a preliminary model of how dispositional mindfulness operated in the context of minority stress among Latino/a sexual minority young adults and their families. We then conducted semi-structured interviews in a life history format with 21 Latino/a sexual minority young adults and 15 family members to test our preliminary model and refine it. We mixed content analysis and grounded theory techniques, whereby we initially used deductive coding with pre-established codes based on our preliminary model, and subsequently used inductive coding to account for novel categories in the interview data that could not be explained by the preliminary model. The refined model revealed pathways by which five constructs of dispositional mindfulness (act with awareness, observe, describe, non-judge, non-react) buffered negative effects of minority stress on psychosocial health in young adults, and were qualitatively associated with compassion, acceptance of sexual minorities, and closeness among family members. Young adults reporting deficiencies in mindfulness reported greater suffering and negative coping related to minority stress. Our model provides a framework to explore modes of resilience and adaptation to minority stress, and offers a basis for further refinement in other affected populations.

Abstract
Recent research in functional genomics shows that social stressors affect the expression of immune response genes. These effects are mediated in part via our adaptive capacity for intracellular molecules to respond to extracellular signals, a process called signal transduction. Under this framework, one-way stressors can be transduced into cellular changes is through central nervous system (CNS) modulation of peripheral neural, endocrine, and molecular activity. Mindfulness meditation is a consciousness discipline used to cultivate attention and self-regulation, and may thus be relevant to the signal transduction process outlined in the social genomics literature. In this opinion article, we briefly review results from existing controlled trials that test the effects of mindfulness meditation on gene expression. We then speculate on a mind-body conceptual model, grounded in existing social genomics theory. In the spirit of hypothesis generation, we argue that mindfulness meditation changes brain activity patterns related to attention, self-regulation, and threat evaluation and so may alter the signal transduction process that regulates the expression of immune response genes.

Abstract
In this study we test the efficacy of Moment-by-Moment in Women's Recovery (MMWR), a mindfulness-based intervention adapted to support women with substance use disorder (SUD) while in residential treatment. We use a parallel-group randomized controlled trial with a time-matched psychoeducation control to test MMWR effects on residential treatment retention. We used clinical staff-determined residential site discharge status and discharge date from the SUD treatment site record to determine retention. We tested for study group differences in retention defined as time to treatment non-completion without improvement (i.e., patient left treatment before completion of the treatment plan and made little or no progress toward achieving treatment goals based on clinical team determination), as well as differences in self-report of study intervention mechanisms of action (i.e., mindfulness, perceived stress, distress tolerance, emotion regulation, distress, affect, and drug and alcohol craving). The analytic timeframe for the survival analysis was from study intervention start date to 150 days later. The sample (N = 200) was female, majority amphetamine/methamphetamine users (76%), Hispanic (58%), with a history of incarceration (62%). By the 150-day analytic endpoint, the sample had 74 (37%) treatment Completers, 42 (21%) still In-residence, 26 (13%) Non-completers with satisfactory progress, and 58 (29%) Non-completers without satisfactory progress. Survival analysis of the intent-to-treat sample showed the risk of non-completion without improvement was lower in MMWR as compared to the control group (adjusted hazard ratio = 0.42, 95% CI: 0.16-1.08, p = .07). Both groups improved on select self-reported mechanism measure scores at immediate post-intervention, but only in the MMWR group did class attendance (dosage) have a large-size correlation with improved mindfulness (r = .61, p < .01), distress tolerance (r = 0.55, p < .01) and positive affect (r = 0.52, p < .01) scores. The hazard ratio for retention was of medium-to-large effect size, suggesting the clinical relevance of adding MMWR to an all-women's, ethnoracially diverse, SUD residential treatment center. An extended curriculum may be helpful considering the protective benefits of class attendance on psychological health indicators.

Abstract
OBJECTIVES The first aim was to test the factor structure and item-loadings of the 10-item Perceived Stress Scale (PSS) when administered to early adolescents. The second aim was to examine associations between PSS factors, mindfulness disposition, and executive function. METHODS We analyzed data collected from 331 students in grade seven (M age=12.4, 48.9% female, 47.1% White, 26.0% Hispanic, 37.8% received free-lunch) classrooms from two ethnically/racially and socio-economically diverse schools. Participants completed paper and pencil self-report measures of stress (PSS), mindfulness disposition (Mindful Awareness Attention Scale, MAAS), and executive function (Behavior Rating Inventory of Executive Function, BRIEF). We tested the statistical association between two factors of the PSS: perceived coping and perceived distress with MAAS and BRIEF. RESULTS A two-factor model of the PSS, inclusive of perceived coping and perceived distress, fit the data better than a one-dimensional model. MAAS and BRIEF scores were inversely associated with PSS distress scores (β = -.62, p <.0001 and β = -.66, p <.0001, respectively), but not PSS coping scores (β = -.04, p = .21 and β = -.02, p = .57, respectively) in a model adjusted for sex, race, and socio-economic status. CONCLUSIONS Two factors in the PSS emerged among early adolescents and differentially associated with mindfulness disposition and executive function to similar magnitudes. Findings encourage future assessment of perceived stress in a more refined manner across developmental stages in order to examine trajectories of perceived distress versus perceived coping in relation to mindfulness disposition and executive function.

Abstract
Objectives: Acupuncture uses needle stimulation upon the body's meridian points to alleviate physical and psychologic symptoms. In clinical practice, acupuncturists often recommend patients to attend follow-up treatment to achieve cumulative benefit over time. Adherence to acupuncture treatment was studied, and demographic and clinical factors were tested that may predict adherence. Design and subjects: A retrospective chart review at an acupuncture teaching clinic was conducted using data from 2014, where patients routinely received recommendations to return for follow-up visits to continue their management of the same health condition. A total of 131 patients were included with an initial consultation in this analysis (mean age = 43 ± 15, 40% male). Outcome measures: Rates of adherence to acupuncture follow-up treatment were determined by tracking whether patients had any subsequent follow-up visits in 30 days after their initial consultation. Demographic and clinical characteristics that differed between adherers (≥1 follow-up visit) and nonadherers (no follow-up visit) were then tested. Among the adherer sample, the authors tested whether these characteristics were associated with a higher number of follow-up visits was tested. Results: Half (50%) of the patient sample adhered to ≥1 follow-up visits in 30 days after their initial consultation. Patients reporting multiple chief complaints were more likely to have a follow-up visit than those with a single complaint (63% vs. 42%, p = 0.02). Receipt of a treatment plan (incidence rate ratio [IRR]: 1.37, p = 0.02) and first follow-up visit within 7 days of initial treatment (IRR: 1.42, p = 0.01) were associated with a higher number of follow-up visits among adherers, after adjusting for covariates. The predicted number of follow-up visits for patients with a treatment plan was 2.5 (standard error [SE] = 0.3) and that for those without a treatment plan was 1.8 (SE = 0.2) among adherers. Conclusion: The rate of return to an acupuncture clinic for follow-up treatment was low (50%). Patient adherence to acupuncture follow-up treatments may be improved by clinical administrative protocols that formalize treatment plans and appointment scheduling.

Abstract
Mindfulness-based interventions (MBIs) are in the fourth decade of adaptation and testing, yet little is known about their level of treatment fidelity. Treatment fidelity is a methodological strategy used to monitor and enhance the reliability and validity of behavioral interventions. The Treatment Fidelity Workgroup of the National Institutes of Health Behavior Change Consortium (BCC) put forth recommendations covering five components of treatment fidelity: design, training, delivery, receipt, and enactment. We conducted a literature review to describe how these five components of treatment fidelity are reported in published main outcomes articles of MBI efficacy trials among adult participants. Our search yielded 202 articles and we identified 25 (12%) described study treatment fidelity. All 25 studies reported on design, n=24 (96%) reported on training, n=23 (92%) reported on delivery, n=23 (92%) reported on receipt, and n=16 (64%) reported on enactment. Eleven (44%) articles analyzed measures of receipt and enactment with a participant outcome. Fourteen (56%) articles reported on all five fidelity components. There was high variation in the way each component was conducted and/or reported, making comparisons across articles difficult. To address the prevailing limitation that the majority of MBI efficacy studies did not detail treatment fidelity, we offer the Treatment Fidelity Tool for MBIs adapted from the BCC guidelines to help researchers monitor and report these methods and measures in a simple and standardized format. By using this tool, researchers have the opportunity to improve the transparency and interpretability of the MBI evidence base.

Abstract
BACKGROUND Many cancer survivors experience fatigue as a nagging symptom lasting years after treatment. To learn of the relevant biological pathways involved in fatigue among cancer survivors, the authors tested for an association between fatigue levels and leukocyte gene expression profiles and determined the specific mediating immune cell types. METHODS A sample of 89 Hispanic/Latino adults aged 60.5 years, 62% of whom were male, who were diagnosed with colorectal cancer and were 2.9 years since diagnosis provided blood for transcriptome profiling and completed a validated measure of fatigue (Multidimensional Fatigue Symptom Inventory-Short Form). The authors applied genome-wide transcriptional profiling of leukocyte RNA to identify gene expression activity associated with fatigue, tested for the activity of specific transcription factors involved in previously established markers of inflammation and immunologic activation, and identified the specific cell types mediating these transcriptional alterations. RESULTS In analyses adjusting for demographic and behavioral health risk factors, results linked fatigue with increased activation of B lymphocytes and CD8-positive T cells, as well as several transcription factors involved in immune activation (nuclear factor κB [NF-κB], signal transducer and activator of transcription [STAT], and cAMP responsive element-binding protein [CREB]). Results also replicated several specific genomic effects previously observed in fatigued cancer survivors, including upregulated expression of α-synuclein (SNCA) and hemoglobin subunits (HBA and HBB). CONCLUSIONS Cancer survivors' heightened fatigue levels may be partially explained by activation of specific immune cell subsets, thereby providing a potential molecular biomarker for clinical interventions targeting the remediation of fatigue.

Abstract
PURPOSE OF REVIEW The purpose of our critical examination is to present results and provide a synthesis of this body of work. RECENT FINDINGS Sleep problems among cancer survivors are gaining research attention. To our knowledge, there have been six randomized control trials published from 2013 to 2015 that test the effects of mindfulness-based interventions (MBIs) on sleep as a primary or secondary outcome. Our examination of the literature highlights important methodological issues and variability among trials. We conclude our review by offering solutions to facilitate more scientific rigor in future studies.

Abstract
Although therapeutic treatments exist for substance use disorder (SUD), about half of individuals who enter treatment leave early and relapse to substance use. Early dropout from residential treatment places individuals at risk of relapse, and women in SUD residential treatment represent a vulnerable population. Evidence gaps persist for the use of mindfulness-based interventions (MBIs) among racially and ethnically diverse women with SUDs, especially regarding the efficacy of MBIs adapted to prevent residential dropout and relapse. We previously developed and pilot tested an MBI, Moment-by-Moment in Women's Recovery (MMWR), adapted to support women with SUD during residential treatment. The 12-session MMWR program tested in the present study integrates relapse prevention, addresses literacy level and trauma experiences and mental health problems, and is relevant to issues surrounding treatment- and relapse-related stressors among women. The primary objective of the current Phase II randomized controlled trial is to adequately test the efficacy of MMWR on residential treatment retention and substance use relapse and determine psychosocial and neural mechanisms of action underlying MMWR. Participants are women in residential SUD treatment from a community-based residential site that serves mainly women who are low-income and racially and ethnically diverse. A subgroup of participants from each treatment group also completes functional and structural neuroimaging assessments before and after the intervention to explore possible structural and functional brain correlates of change associated with participation in the MMWR program. Findings are expected to inform the utility of adapting MBIs to improve treatment success among vulnerable women in SUD residential treatment.

Abstract
BACKGROUND The objective of this randomized clinical experiment was to test the influence of a mindfulness meditation practice, when delivered during 1 session of active chemotherapy administration, on the acute salivary cortisol response as a marker of neuroendocrine system activity in cancer patients. METHODS A mindfulness, attention-control, or resting exposure was assigned to 57 English- or Spanish-speaking colorectal cancer patients at 1 county oncology clinic and 1 university oncology clinic at the start of chemotherapy. Saliva samples were collected at the start of chemotherapy and at subsequent 20-minute intervals during the first 60 minutes of chemotherapy (4 samples in all). Self-reporting on biobehavioral assessments after chemotherapy included distress, fatigue, and mindfulness. RESULTS An area-under-the-curve analysis (AUC) showed a relative increase in cortisol reactivity in the mindfulness group after adjustments for biological and clinical measures (β = 123.21; P = .03). More than twice as many patients in the mindfulness group versus the controls displayed a cortisol rise from the baseline to 20 minutes (69% vs 34%; P = .02). AUC values were uncorrelated with biobehavioral measure scores, although mindfulness scores were inversely correlated with fatigue (r = -0.46; P < .01) and distress scores (r = -0.54; P < .01). CONCLUSIONS Findings suggest that mindfulness practice during chemotherapy can reduce the blunting of neuroendocrine profiles typically observed in cancer patients. Implications include support for the use of mindfulness practice in integrative oncology. Cancer 2017;123:3088-96. © 2017 American Cancer Society.

Abstract
OBJECTIVES To compare changes in food-purchasing knowledge, self-efficacy, and behavior after viewing nutrition education videos among Los Angeles, California Latinas responsible for household grocery shopping. METHODS From February to May 2015, a convenience sample of 113 Latinas watched 1 video (El Carrito Saludable) featuring MyPlate guidelines applied to grocery shopping (1-video intervention) and another convenience sample of 105 Latinas watched 2 videos (El Carrito Saludable and Ser Consciente), the latter featuring mindfulness to support attention and overcome distractions while grocery shopping (2-video intervention). We administered questionnaires before and after intervention. A preselected sample in each intervention condition (n = 72) completed questionnaires at 2-months after intervention and provided grocery receipts (before and 2-months after intervention). RESULTS Knowledge improved in both intervention groups (P < .001). The 2-video group improved more in self-efficacy and use of a shopping list (both P < .05) and purchased more healthy foods (d = 0.60; P < .05) at 2 months than did the 1-video group. CONCLUSIONS Culturally tailored videos that model food-purchasing behavior and mindfulness show promise for improving the quality of foods that Latinas bring into the home.

Abstract
OBJECTIVE Complementary and integrative health (CIH) use among Hispanic adults with colorectal cancer (CRC) diagnosis is not well documented. Understanding the prevalence and patterns of CIH use among Hispanics offers insights to uncover potential needs for clinical services. DESIGN Participants were age 21 years or older with a first-time diagnosis of CRC from population-based cancer registries in California. In-person and/or telephone-based interviews were administered to collect data on CIH use. Demographic and clinical diagnosis data were abstracted from medical records. Descriptive statistical and logistic regression was used to analyze the frequencies and associations between selected patient characteristics and CIH use. RESULTS Among 631 Hispanic patients, 40.1% reported ever using CIH. Herbal products/dietary supplements were used most often (35.3%), followed by bodywork (16.5%), mind-body practices (7.8%), and homeopathy (6.7%). About 60% of participants reported CIH use to address specific health conditions; however, most patients did not discuss CIH use with their physicians (76.3%). Women reported higher CIH use than did men (45.1% versus 35.9%; odds ratio, 1.49 [95% confidence interval, 1.07-2.08]; p = 0.02). CIH use did not differ by clinical stage, time since diagnosis, or preferred language. CONCLUSIONS CIH use is prevalent among Hispanic patients with CRC, especially women. Little communication about CIH use occurs between participants and their healthcare providers. Efforts aimed at improving integrative oncology services provide an opportunity to address such gaps in healthcare service.

Abstract
OBJECTIVE Mindfulness-based interventions (MBIs) include the application of meditation and mind-body practices used to promote mindful awareness in daily life. Operationalizing the construct of mindfulness is important in order to determine mechanisms of therapeutic change elicited by mindfulness practice. In addition to existing state and trait measures of mindfulness, process measures are needed to assess the ways in which individuals apply mindfulness in the context of their practice. METHOD This report details three independent studies (qualitative interview, N = 8; scale validation, N = 134; and replication study, N = 180) and the mixed qualitative-quantitative methodology used to develop and validate the Applied Mindfulness Process Scale (AMPS), a 15-item process measure designed to quantify how mindfulness practitioners actively use mindfulness to remediate psychological suffering in their daily lives. RESULTS In Study 1, cognitive interviewing yielded a readily comprehensible and accessible scale of 15 items. In Study 2, exploratory factor analysis derived a potential three-factor solution: decentering, positive emotion regulation, and negative emotion regulation. In Study 3, confirmatory factor analysis verified better model fit with the three-factor structure over the one-factor structure. CONCLUSIONS AMPS functions as a measure to quantify the application of mindfulness and processes of change in the context of MBIs and general mindfulness practice.

Abstract
Mindfulness meditation represents a mental training framework for cultivating the state of mindful awareness in daily life. Recently, there has been a surge of interest in how mindfulness meditation improves human health and well-being. Although studies have shown that mindfulness meditation can improve self-reported measures of disease symptomatology, the effect that mindfulness meditation has on biological mechanisms underlying human aging and disease is less clear. To address this issue, we conducted the first comprehensive review of randomized controlled trials examining the effects of mindfulness meditation on immune system parameters, with a specific focus on five outcomes: (1) circulating and stimulated inflammatory proteins, (2) cellular transcription factors and gene expression, (3) immune cell count, (4) immune cell aging, and (5) antibody response. This analysis revealed substantial heterogeneity across studies with respect to patient population, study design, and assay procedures. The findings suggest possible effects of mindfulness meditation on specific markers of inflammation, cell-mediated immunity, and biological aging, but these results are tentative and require further replication. On the basis of this analysis, we describe the limitations of existing work and suggest possible avenues for future research. Mindfulness meditation may be salutogenic for immune system dynamics, but additional work is needed to examine these effects.

Abstract
PURPOSE The aim of this paper was to determine individual and shared levels of psychosocial, behavioral, and symptomological health characteristics among Hispanics with recent history of cancer and their primary social support person (PSSP) in the years following diagnosis. PATIENTS AND METHODS Recruited from a population-based cohort study were 409 Hispanic patients with a previous diagnosis of colorectal cancer. Forty-seven patients identified a PSSP, who assists with medical decision-making and health-related matters, who also participated in the study. Current behavioral (smoking, alcohol use, physical activity, and complementary and alternative medicine use), psychosocial (stress and mindfulness), and physical symptom (fatigue) data were obtained using validated instruments. Analyses tested the individual and shared (between patients and PSSPs) variance in these health measures. RESULTS The sample was diagnosed on average 3.1 years (standard deviation = 1.7) prior to assessment. PSSPs were mainly spouses/partners (63%) or children (28%) of patients. Among patients, stress was positively associated with being a current smoker (p < 0.01) and with fatigue (r = 0.45, p < 0.001); stress was negatively correlated with mindfulness (r = -0.41, p < 0.001); mindfulness was negatively associated with smoking (odds ratio (OR) = 0.72, p < 0.01) and alcohol consumption (OR = 0.83, p < 0.05); the inverse relationship between mindfulness and fatigue was partially mediated through lower levels of stress (β = -0.17, p < 0.001). Similar patterns were observed among PSSPs. Patient mindfulness was negatively correlated with PSSP stress (r = -0.45, p < 0.01). Complementary and alternative medicine use showed interdependence between patients and PSSPs for use of herbal remedies (OR = 6.2; p < 0.01) and bodywork (OR = 8.3, p < 0.05). CONCLUSION Hispanic colorectal cancer patients and their PSSP share a common health milieu in the years following a cancer diagnosis, offering opportunities for advancing interpersonal intervention approaches in cancer care.

Abstract
IMPORTANCE Sleep disturbances are most prevalent among older adults and often go untreated. Treatment options for sleep disturbances remain limited, and there is a need for community-accessible programs that can improve sleep. OBJECTIVE To determine the efficacy of a mind-body medicine intervention, called mindfulness meditation, to promote sleep quality in older adults with moderate sleep disturbances. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial with 2 parallel groups conducted from January 1 to December 31, 2012, at a medical research center among an older adult sample (mean [SD] age, 66.3 [7.4] years) with moderate sleep disturbances (Pittsburgh Sleep Quality Index [PSQI] >5). INTERVENTIONS A standardized mindful awareness practices (MAPs) intervention (n = 24) or a sleep hygiene education (SHE) intervention (n = 25) was randomized to participants, who received a 6-week intervention (2 hours per week) with assigned homework. MAIN OUTCOMES AND MEASURES The study was powered to detect between-group differences in moderate sleep disturbance measured via the PSQI at postintervention. Secondary outcomes pertained to sleep-related daytime impairment and included validated measures of insomnia symptoms, depression, anxiety, stress, and fatigue, as well as inflammatory signaling via nuclear factor (NF)-κB. RESULTS Using an intent-to-treat analysis, participants in the MAPs group showed significant improvement relative to those in the SHE group on the PSQI. With the MAPs intervention, the mean (SD) PSQIs were 10.2 (1.7) at baseline and 7.4 (1.9) at postintervention. With the SHE intervention, the mean (SD) PSQIs were 10.2 (1.8) at baseline and 9.1 (2.0) at postintervention. The between-group mean difference was 1.8 (95% CI, 0.6-2.9), with an effect size of 0.89. The MAPs group showed significant improvement relative to the SHE group on secondary health outcomes of insomnia symptoms, depression symptoms, fatigue interference, and fatigue severity (P < .05 for all). Between-group differences were not observed for anxiety, stress, or NF-κB, although NF-κB concentrations significantly declined over time in both groups (P < .05). CONCLUSIONS AND RELEVANCE The use of a community-accessible MAPs intervention resulted in improvements in sleep quality at immediate postintervention, which was superior to a highly structured SHE intervention. Formalized mindfulness-based interventions have clinical importance by possibly serving to remediate sleep problems among older adults in the short term, and this effect appears to carry over into reducing sleep-related daytime impairment that has implications for quality of life.

Abstract
Background Mindfulness-based interventions (MBIs) have previously been associated with structural gray matter changes in normal healthy adults. However, it remains unknown if standardized MBIs can induce similar changes in older adults and those with health complaints as well. The objective of this investigation was to examine the effect of a standardized MBI on the gray matter tissue of older adults with sleep disturbances. Methods This exploratory single-group pilot longitudinal study examined local gray matter changes over a six-week MBI period. Participants included six older adult community volunteers (M=66.5 years of age, SD=5.5, range=58–75; 66% female) with sleep disturbances recruited through advertisement in local newspapers/flyers posted at a university medical center and affiliated clinics in Los Angeles, CA. The MBI was delivered as a weekly, two-hour, six-session, group-based course in mindfulness meditation. Gray matter was measured voxel-wise pre- and post-intervention. Results A significant gray matter increase was identified within the precuneus, possibly implicating meditation-induced changes of the default mode network. In contrast, observed significant gray matter decreases may have been driven by MBI-related remediation of brain architecture subserving sleep complaints. Conclusions Exploratory findings suggest that mindfulness meditation practice is associated with a detectable alteration of cerebral gray matter in older adults.

Abstract
This field intervention trial evaluated the effect of a 5-week mindfulness-based curriculum on teacher-ratings of student classroom behavior at a Richmond, CA public elementary school, and examined if the addition of more sessions provided added benefit to student outcomes. Seventeen teachers reported on the classroom behaviors of 409 children (83 % enrolled in a California free lunch program and 95.7 % ethnic minority) in kindergarten through sixth grade at pre-intervention, immediate post-intervention, and 7 weeks post-intervention. Results showed that teachers reported improved classroom behavior of their students (i.e., paying attention, self-control, participation in activities, and caring/respect for others) that lasted up to 7 weeks post-intervention. Overall, improvements were not bolstered by the addition of extra sessions, with the exception of paying attention. The implications of this study are limited due to the lack of a mindfulness program-naïve control group, yet findings suggest that mindfulness training might benefit teacher-based perceptions of improved classroom behavior in a public elementary school, which has practice implications for improving the classroom learning environment for lower-income and ethnically-diverse children.

Abstract
PURPOSE Poorly managed stress leads to detrimental physical and psychological consequences that have implications for individual and community health. Evidence indicates that U.S. adults predominantly use unhealthy strategies for stress management. This study examines the impact of a community-based mindfulness training program on stress reduction. DESIGN This study used a one-group pretest-posttest design. SETTING The study took place at the UCLA Mindful Awareness Research Center in urban Los Angeles. SUBJECTS A sample of N = 127 community residents (84% Caucasian, 74% female) were included in the study. INTERVENTION Participants received mindfulness training through the Mindful Awareness Practices (MAPs) for Daily Living I. MEASURES Mindfulness, self-compassion, and perceived stress were measured at baseline and postintervention. ANALYSIS Paired-sample t-tests were used to test for changes in outcome measures from baseline to postintervention. Hierarchical regression analysis was fit to examine whether change in self-reported mindfulness and self-compassion predicted postintervention perceived stress scores. RESULTS There were statistically significant improvements in self-reported mindfulness (t = -10.67, p < .001, d = .90), self-compassion (t = -8.50, p < .001, d = .62), and perceived stress (t = 9.28, p < .001, d = -.78) at postintervention. Change in self-compassion predicted postintervention perceived stress (β = -.44, t = -5.06, p < .001), but change in mindfulness did not predict postintervention perceived stress (β = -.04, t = -.41, p = .68). CONCLUSION These results indicate that a community-based mindfulness training program can lead to reduced levels of psychological stress. Mindfulness training programs such as MAPs may offer a promising approach for general public health promotion through improving stress management in the urban community.

Abstract
Sleep problems are prevalent among older adults, often persist untreated, and are predictive of health detriments. Given the limitations of conventional treatments, non-pharmacological treatments such as mindfulness-based interventions (MBIs) are gaining popularity for sleep ailments. However, nothing is yet known about the impact of MBIs on sleep in older adults with prodromal sleep disturbances. This article details the design and methodology of a 6-week parallel-group RCT calibrated to test the treatment effect of the Mindful Awareness Practices (MAPs) program versus sleep hygiene education for improving sleep quality, as the main outcome, in older adults with prodromal sleep disturbances. Older adults with current sleep disturbances will be recruited from the urban Los Angeles community. Participants will be randomized into two standardized treatment conditions, MAPs and sleep hygiene education. Each condition will consist of weekly 2-hour group-based classes over the course of the 6-week intervention. The primary objective of this study is to determine if mindfulness meditation practice as engaged through the MAPs program leads to improved sleep quality relative to sleep hygiene education in older adults with prodromal sleep disturbances.

Abstract
Mindfulness-based interventions (MBIs) targeting eating behaviours have gained popularity in recent years. A literature review was conducted to determine the effectiveness of MBIs for treating obesity-related eating behaviours, such as binge eating, emotional eating and external eating. A search protocol was conducted using the online databases Google Scholar, PubMed, PsycINFO and Ovid Healthstar. Papers were required to meet the following criteria to be included in this review: (i) describe a MBI or the use of mindfulness exercises as part of an intervention; (ii) include at least one obesity-related eating behaviour as an outcome; (iii) include quantitative outcomes; and (iv) be published in English in a peer-reviewed journal. A total of N = 21 papers were included in this review. Interventions used a variety of approaches to implement mindfulness training, including combined mindfulness and cognitive behavioural therapies, mindfulness-based stress reduction, acceptance-based therapies, mindful eating programmes, and combinations of mindfulness exercises. Targeted eating behaviour outcomes included binge eating, emotional eating, external eating and dietary intake. Eighteen (86%) of the reviewed studies reported improvements in the targeted eating behaviours. Overall, the results of this first review on the topic support the efficacy of MBIs for changing obesity-related eating behaviours, specifically binge eating, emotional eating and external eating.

Abstract
Adolescence is characterized by incredible development in the prefrontal cortex of the brain, which is responsible for behavioral and emotional self-regulation, and higher order cognitive decision-making skills (that is, executive function). Typically late prefrontal cortical development and its integration with limbic areas of the brain associated with reward, pleasure, novelty seeking, and emotion can contribute to substance misuse vulnerability during adolescence. In this chapter, literature on the developmental integration of the prefrontal cortex with emotion and motivation centers of the brain is reviewed. Then this research is applied to school-based adolescent substance misuse prevention, highlighting two examples of preventive interventions incorporating neurocognitive models into comprehensive prevention approaches. Finally, innovative strategies (for example, mindfulness training) for promoting neurocognition as a mediator to substance misuse vulnerability are discussed.

Abstract
We examined feasibility, acceptability, and benefits of a mindfulness-based relapse prevention (MBRP) intervention in a racially and ethnically diverse sample of 318 low-income women in substance use disorder treatment (2003-2006). The study used a single group, repeated measures design. Participant satisfaction was high (M = 3.4, SD = .3), but completion was modest (36%). Linear regressions examining change in addiction severity and psychological functioning by dosage showed that higher dosage was associated with reduced alcohol (β = -.07, p < .05), drug severity (β = -.04, p < .05), and perceived stress (β = -2.29, p < .05) at 12 months. Further research on MBRP efficacy for this population is warranted. The study's limitations are noted.

Abstract
The cultivation of mindfulness as an approach to human perception through the practice of meditation has become an increasingly popular treatment for medical and psychological symptoms and as a topic of scientific investigation. Substance user programs are also increasingly embracing this treatment strategy as either a stand-alone therapeutic modality or a complement to ongoing treatment. In this article, I supply an introduction to the special theme issue concerning mindfulness and substance use intervention by first providing a brief historical account of the secular Mindfulness-Based Stress Reduction program to introduce new readers to the more general topic of mindfulness-based interventions (MBIs), and to contextualize historical publishing trends observed in mindfulness research across the past four decades. I then examine the implications of MBIs for substance use, misuse, and addiction, especially in areas related to craving and suffering. To conclude, I outline the empirical and conceptual compendium of contributions offered in this special issue.

Abstract
Adolescence is marked by several key development-related changes, including neurocognitive changes. Cognitive abilities associated with self-regulation are not fully developed until late adolescence or early adulthood whereas tendencies to take risks and seek thrilling and novel experience seem to increase significantly throughout this phase, resulting in a discrepancy between increased susceptibility to poor regulation and lower ability to exercise self-control. Increased vulnerability to drug use initiation, maintenance, and dependence during adolescence may be explained based on this imbalance in the self-regulation system. In this paper, we highlight the relevance of schools as a setting for delivering adolescent drug use prevention programs that are based on recent findings from neuroscience concerning adolescent brain development. We discuss evidence from school-based as well as laboratory research that suggests that suitable training may improve adolescents' executive brain functions that underlie self-regulation abilities and, as a result, help prevent drug use and abuse. We note that considerable further research is needed in order (1) to determine that self-regulation training has effects at the neurocognitive level and (2) to effectively incorporate self-regulation training based on neuropsychological models into school-based programming.

Abstract
Spirituality has long been integrated into treatments for addiction. However, how spirituality differs from other related constructs and implications for recovery among nonspiritual persons remains a source of discussion. This article examines ways in which spirituality is delineated, identifies variables that might mediate the relations between spirituality and recovery from substance abuse disorders, describes distinctions between spiritual and nonspiritual facets of addictions treatment, and suggests means to assist in further clarification of this construct.

Abstract
OBJECTIVE By enhancing positive affect and cognitive flexibility, mindfulness practice may promote reappraisal of stressors. We hypothesized that coping through mindful reappraisal would be common among mindfulness practitioners from an array of traditions. METHOD A sample of 118 meditation practitioners completed an online survey comprising assessments of the prevalence and frequency of mindful reappraisal, as well as measures of well-being and distress. RESULTS Regular use of mindful reappraisal was reported by over half of the sample and was significantly correlated with years of meditation practice (r = .31, p = .01), meditation practice days per month (r = .30, p = .001), and meditation hours per week (r = .30, p = .001). Controlling for frequency of meditation practice and trait mindfulness, mindful reappraisal frequency explained significant portions of variance in well-being (P <.001) and distress (P <.001). CONCLUSIONS Meditation practitioners commonly employ mindful reappraisal coping as a positive emotion regulatory strategy in stressful contexts.

Abstract
BACKGROUND Leprosy is a chronic infection of the skin and peripheral nerves caused by the bacterium Mycobacterium leprae, which causes peripheral insensitivity and disfigurements of the skin, limbs, and digits. Social stigma is a common consequence of leprosy and may differ according to level of physical disfigurement and geographic location. The objective of this study was to assess social stigma encountered by patients with leprosy in clinical settings located in rural Tanzania and urban USA and to compare the social stigma reported in these regions. METHODS A total of 56 respondents were recruited from one leprosy inpatient facility in Shirati, Tanzania (n = 28), and one outpatient clinic in Los Angeles, USA (n = 28). Cross-sectional data were obtained from face-to-face interviews, which were conducted with respondents at each clinic location. Measures of perceived stigma were assessed in family relationship, vocational, social interaction, and interpersonal contexts. RESULTS Patients in Tanzania, as compared with those in the USA, reported significantly higher levels of stigma in family relationship and vocational contexts. Tanzanian patients also reported higher levels of stigma in social interaction and self-esteem contexts, but these differences were marginally significant and may reflect the small sample size. CONCLUSIONS Leprosy-related social stigma is a major problem in regions of both developed and developing countries; however, patients with leprosy in developing countries reported higher levels of stigma in four social contexts. A public health role in dermatology is discussed as an agent of early diagnosis, control, and education in order to reduce social stigma and promote social rehabilitation.

Abstract
BACKGROUND Although yoga and meditation have been used for stress reduction with reported improvement in inflammation, little is known about the biological mechanisms mediating such effects. The present study examined if a yogic meditation might alter the activity of inflammatory and antiviral transcription control pathways that shape immune cell gene expression. METHODS Forty-five family dementia caregivers were randomized to either Kirtan Kriya Meditation (KKM) or Relaxing Music (RM) listening for 12 min daily for 8 weeks and 39 caregivers completed the study. Genome-wide transcriptional profiles were collected from peripheral blood leukocytes sampled at baseline and 8-week follow-up. Promoter-based bioinformatics analyses tested the hypothesis that observed transcriptional alterations were structured by reduced activity of the pro-inflammatory nuclear factor (NF)-κB family of transcription factors and increased activity of Interferon Response Factors (IRFs; i.e., reversal of patterns previously linked to stress). RESULTS In response to KKM treatment, 68 genes were found to be differentially expressed (19 up-regulated, 49 down-regulated) after adjusting for potentially confounded differences in sex, illness burden, and BMI. Up-regulated genes included immunoglobulin-related transcripts. Down-regulated transcripts included pro-inflammatory cytokines and activation-related immediate-early genes. Transcript origin analyses identified plasmacytoid dendritic cells and B lymphocytes as the primary cellular context of these transcriptional alterations (both p<.001). Promoter-based bioinformatic analysis implicated reduced NF-κB signaling and increased activity of IRF1 in structuring those effects (both p<.05). CONCLUSION A brief daily yogic meditation intervention may reverse the pattern of increased NF-κB-related transcription of pro-inflammatory cytokines and decreased IRF1-related transcription of innate antiviral response genes previously observed in healthy individuals confronting a significant life stressor.

Abstract
PURPOSE The cognitive tendency toward mindfulness may influence the enactment of health and risk behaviors by its bringing increased attention to and awareness of decision-making processes underlying behavior. The present study examined the moderating effect of trait mindfulness on associations between intentions to smoke (ITS)/smoking refusal self-efficacy (SRSE) and smoking frequency. METHODS Self-reports from Chinese adolescents (N = 5,287; mean age = 16.2 years, standard deviation = .7; 48.8% female) were collected in 24 schools. Smoking frequency was regressed on latent factor interactions Mindful Attention Awareness Scale*ITS and Mindful Attention Awareness Scale*SRSE, adjusting for school clustering effects and covariates. RESULTS Both interaction terms were significant in cross-sectional analyses and showed that high ITS predicted higher smoking frequency among those low, relative to high, in trait mindfulness, whereas low SRSE predicted higher smoking frequency among those low, relative to high, in trait mindfulness. CONCLUSIONS Findings suggest trait mindfulness possibly shields against decision-making processes that place adolescents at risk for smoking.

Abstract
Mindfulness refers to an enhanced attention to and awareness of present moment experience. This study examined how trait mindfulness, as measured with six items from Mindfulness Attention Awareness Scale, might influence adolescent cigarette smoking frequency through its impact on depressive affect, anger affect and perceived stress mediators. Self-reported data from Chinese adolescents (N = 5287, mean age = 16.2 years, SD = 0.7; 48.8% females) were collected within 24 schools. The product of coefficients test was used to determine significant mediation paths. Results from baseline cross-sectional data indicated that trait mindfulness had a significant indirect effect on past 30-day smoking frequency through depressive affect, anger affect and perceived stress mediators. Results from 13-month longitudinal data indicated that these indirect effects remained significant for depressive affect and perceived stress but not for anger affect. Findings from this study may suggest that heightening mindfulness among adolescents may indirectly reduce cigarette smoking perhaps by improving affect regulation competencies.
