The high incidence of poor sleep and associated negative health consequences substantiates the need for effective behavioral sleep interventions. We offer an integrative model of sleep disturbance whereby key risk factors for compromised sleep quality and quantity are targeted through mindfulness practice-namely, experiential awareness, attentional control, and acceptance. Theoretical considerations and burgeoning evidence suggest that mindfulness-based interventions (MBIs) may be promising treatments for improving sleep outcomes. However, evidence is mixed due to heterogeneity in design and methods across studies. More rigorous RCTs are needed to determine the efficacy and underlying mechanisms of MBI's for sleep. MBIs that are affordable, accessible, and scalable are needed to improve sleep outcomes at the population level.

We conducted a 26-month follow-up of a previously reported 12-month study that compared mindfulness-based cognitive therapy (MBCT) to a rigorous active control condition (ACC) for depressive relapse/recurrence prevention and improvements in depressive symptoms and life satisfaction. Participants in remission from major depression were randomized to an 8-week MBCT group (n = 46) or the ACC (n = 46). Outcomes were assessed at baseline; postintervention; and 6, 12, and 26 months. Intention-to-treat analyses indicated no differences between groups for any outcome over the 26-month follow-up. Time to relapse results (MBCT vs. ACC) indicated a hazard ratio = .82, 95% CI [.34, 1.99]. Relapse rates were 47.8% for MBCT and 50.0% for ACC. Piecewise analyses indicated that steeper declines in depressive symptoms in the MBCT vs. the ACC group from postintervention to 12 months were not maintained after 12 months. Both groups experienced a marginally significant rebound of depressive symptoms after 12 months but were still improved at 26 months compared to baseline (b = -4.12, p <= .008). Results for life satisfaction were similar. In sum, over a 26-month follow-up, MBCT was no more effective for preventing depression relapse/recurrence, reducing depressive symptoms, or improving life satisfaction than a rigorous ACC. Based on epidemiological data and evidence from prior depression prevention trials, we discuss the possibility that both MBCT and ACC confer equal therapeutic benefit. Future studies that include treatment as usual (TAU) control conditions are needed to confirm this possibility and to rule out the potential role of time-related effects. Overall findings underscore the importance of comparing MBCT to TAU as well as to ACCs.

This study examined the potential buffering role of trait mindfulness in the relationship between perceived discrimination and depressive symptoms in a community-based sample of racial and ethnic minority adults. Analyses conducted on 97 participants indicated that self-reported trait mindfulness moderated the relationship between perceived discrimination and depressive symptoms. Individuals low in mindfulness experienced elevated depressive symptoms at high levels of discrimination. However, individuals high in mindfulness reported lower depressive symptoms at high levels of discrimination. Results remained robust when controlling for potential confounding effects of age, sex, and income. Results suggest mindfulness is an important individual difference that may confer resilience for racial and ethnic minority communities who experience disproportionate levels of discrimination-related stressors and health disparities. Findings point to the potential utility of interventions that target mindfulness as a modifiable skill that can be used specifically to cope with discrimination. Socio-cultural considerations for the use of mindfulness-based approaches in racial and ethnic minority communities are discussed.

BACKGROUND:Elevated stress is associated with adverse cardiovascular disease outcomes and accounts in part for the poorer recovery experienced by women compared with men after myocardial infarction (MI). Psychosocial interventions improve outcomes overall but are less effective for women than for men with MI, suggesting the need for different approaches. Mindfulness-based cognitive therapy (MBCT) is an evidence-based intervention that targets key psychosocial vulnerabilities in women including rumination (i.e., repetitive negative thinking) and low social support. This article describes the rationale and design of a multicenter randomized controlled trial to test the effects of telephone-delivered MBCT (MBCT-T) in women with MI. METHODS:We plan to randomize 144 women reporting elevated perceived stress at least two months after MI to MBCT-T or enhanced usual care (EUC), which each involve eight weekly telephone sessions. Perceived stress and a set of patient-centered health outcomes and potential mediators will be assessed before and after the 8-week telephone programs and at 6-month follow-up. We will test the hypothesis that MBCT-T will be associated with greater 6-month improvements in perceived stress (primary outcome), disease-specific health status, quality of life, depression and anxiety symptoms, and actigraphy-based sleep quality (secondary outcomes) compared with EUC. Changes in mindfulness, rumination and perceived social support will be evaluated as potential mediators in exploratory analyses. CONCLUSIONS:If found to be effective, this innovative, scalable intervention may be a promising secondary prevention strategy for women with MI experiencing elevated perceived stress.

Two emotion regulation strategies-cognitive reappraisal and acceptance-are both associated with beneficial psychological health outcomes over time. However, it remains unclear whether these 2 strategies are associated with differential consequences for emotion, physiology, or perceived cognitive costs in the short-term. The present study used a within-subjects design to examine the effects of reappraisal (reframing one's thoughts) and acceptance (accepting feelings without trying to control or judge them) on the subjective experience of negative emotions, positive emotions, and physiological responses during and following recovery from sad film clips shown in the laboratory. Participants also reported on perceived regulatory effort, difficulty, and success after deploying each emotion regulation strategy. In 2 samples of participants (N = 142), reappraisal (vs. acceptance) was associated with larger decreases in negative and larger increases in positive emotions, both during the film clips and recovery period. However, acceptance was perceived as less difficult to deploy than reappraisal, and was associated with a smaller dampening of skin conductance level (indicating more successful regulation) during the film clips in 1 sample. These results suggest that reappraisal and acceptance may exert differential short-term effects: Whereas reappraisal is more effective for changing subjective experiences in the short term, acceptance may be less difficult to deploy and be more effective at changing one's physiological response. Thus, these 2 strategies may both be considered "effective" for different reasons. (PsycINFO Database Record

The purpose of this study was to test the association between a self-report measure of 24-hour adherence to antihypertensive medication and blood pressure (BP) among African Americans. The primary analysis included 3558 Jackson Heart Study participants taking antihypertensive medication who had adherence data for at least one study examination. Nonadherence was defined by self-report of not taking one or more prescribed antihypertensive medications, identified during pill bottle review, in the past 24 hours. Nonadherence and clinic BP were assessed at Exam 1 (2000-2004), Exam 2 (2005-2008), and Exam 3 (2009-2013). Associations of nonadherence with clinic BP and uncontrolled BP (systolic BP >/= 140 mm Hg or diastolic BP >/= 90 mm Hg) were evaluated using unadjusted and adjusted linear and Poisson repeated measures regression models. The prevalence of nonadherence to antihypertensive medications was 25.4% at Exam 1, 28.7% at Exam 2, and 28.5% at Exam 3. Nonadherence was associated with higher systolic BP (3.38 mm Hg) and diastolic BP (1.47 mm Hg) in fully adjusted repeated measures analysis. Nonadherence was also associated with uncontrolled BP (prevalence ratio = 1.26; 95% confidence interval = 1.16-1.37). This new self-report measure may be useful for identifying nonadherence to antihypertensive medication in future epidemiologic studies.
