RESUMO
OBJECTIVE: Despite the heightened urgency of the current prescription opioid crisis, few psychotherapies have been evaluated for chronic pain patients receiving long-term opioid analgesics. Current psychological pain treatments focus primarily on ameliorating negative affective processes, yet basic science suggests that risk for opioid misuse is linked with a dearth of positive affect. Interventions that modulate positive psychological processes may produce therapeutic benefits among patients with opioid-treated chronic pain. The aim of this study was to conduct a theory-driven mechanistic analysis of proximal outcome data from a Stage 2 randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE), an integrative intervention designed to promote positive psychological health. METHOD: Patients with opioid-treated chronic pain (N = 95; age = 56.8 ± 11.7; 66% female) were randomized to 8 weeks of therapist-led MORE or support group (SG) interventions. A latent positive psychological health variable comprised of positive affect, meaning in life, and self-transcendence measures was examined as a mediator of the effect of MORE on changes in pain severity at posttreatment and opioid misuse risk by 3-month follow-up. RESULTS: Participants in MORE reported significantly greater reductions in pain severity by posttreatment (p = .03) and opioid misuse risk by 3-month follow-up (p = .03) and significantly greater increases in positive psychological health (p < .001) than SG participants. Increases in positive psychological health mediated the effect of MORE on pain severity by posttreatment (p = .048), which in turn predicted decreases in opioid misuse risk by follow-up (p = .02). CONCLUSIONS: Targeting positive psychological mechanisms via MORE and other psychological interventions may reduce opioid misuse risk among chronic pain patients receiving long-term opioid therapy.

BACKGROUND: Among opioid-treated chronic pain patients, deficient response inhibition in the context of emotional distress may contribute to maladaptive pain coping and prescription opioid misuse. Interventions that aim to bolster cognitive control and reduce emotional reactivity (e.g., mindfulness) may remediate response inhibition deficits, with consequent clinical benefits. PURPOSE: To test the hypothesis that a mindfulness-based intervention, Mindfulness-Oriented Recovery Enhancement (MORE), can reduce the impact of clinically relevant, negative affective interference on response inhibition function in an opioid-treated chronic pain sample. METHODS: We examined data from a controlled trial comparing adults with chronic pain and long-term prescription opioid use randomized to either MORE (n = 27) treatment or to an active support group comparison condition (n = 30). Participants completed an Emotional Go/NoGo Task at pre- and post-treatment, which measured response inhibition in neutral and clinically relevant, negative affective contexts (i.e., exposure to pain-related visual stimuli). RESULTS: Repeated-measures analysis of variance indicated that compared with the support group, participants in MORE evidenced significantly greater reductions from pre- to post-treatment in errors of commission on trials with pain-related distractors relative to trials with neutral distractors, group × time × condition F(1,55) = 4.14, p = .047, η2partial = .07. Mindfulness practice minutes and increased nonreactivity significantly predicted greater emotional response inhibition. A significant inverse association was observed between improvements in emotional response inhibition and treatment-related reductions in pain severity by 3-month follow-up. CONCLUSIONS: Study results provide preliminary evidence that MORE enhances inhibitory control function in the context of negative emotional interference.

Substance use disorders (SUDs) are a pervasive public health problem with deleterious consequences for individuals, families, and society. Furthermore, SUD intervention is complicated by the continuous possibility of relapse. Despite decades of research, SUD relapse rates remain high, underscoring the need for more effective treatments. Scientific findings indicate that SUDs are driven by dysregulation of neural processes underlying reward learning and executive functioning. Emerging evidence suggests that mindfulness training can target these neurocognitive mechanisms to produce significant therapeutic effects on SUDs and prevent relapse. The purpose of this manuscript is to review the cognitive, affective, and neural mechanisms underlying the effects of mindfulness-based interventions (MBIs) on SUDs. We discuss the etiology of addiction and neurocognitive processes related to the development and maintenance of SUDs. We then explore evidence supporting use of MBIs for intervening in SUDs and preventing relapse. Finally, we provide clinical recommendations about how these therapeutic mechanisms might be applied to intervening in SUDs and preventing relapse.
RESUMO
Contemporary advances in addiction neuroscience have paralleled increasing interest in the ancient mental training practice of mindfulness meditation as a potential therapy for addiction. In the past decade, mindfulness-based interventions (MBIs) have been studied as a treatment for an array addictive behaviors, including drinking, smoking, opioid misuse, and use of illicit substances like cocaine and heroin. This article reviews current research evaluating MBIs as a treatment for addiction, with a focus on findings pertaining to clinical outcomes and biobehavioral mechanisms. Studies indicate that MBIs reduce substance misuse and craving by modulating cognitive, affective, and psychophysiological processes integral to self-regulation and reward processing. This integrative review provides the basis for manifold recommendations regarding the next wave of research needed to firmly establish the efficacy of MBIs and elucidate the mechanistic pathways by which these therapies ameliorate addiction. Issues pertaining to MBI treatment optimization and sequencing, dissemination and implementation, dose-response relationships, and research rigor and reproducibility are discussed.

Background: Internet gaming disorder (IGD) is characterized by signs and symptoms similar to substance use and gambling disorders, and associated with psychosocial impairments. Research suggests that maladaptive gaming-related cognitions and coping may be implicated in IGD; therefore, interventions for IGD need to target these underlying mechanisms. Mindfulness-based treatment is effective in changing maladaptive cognitive processes and increasing adaptive coping among people with addictions. Aims: This study used data from an RCT of Mindfulness-Oriented Recovery Enhancement (MORE) for IGD to further examine changes in maladaptive gaming-related cognitions and positive reappraisal as mediators of the effects of MORE on IGD signs/symptoms. Methods: Participants (N = 30, Age M = 25.0, SD = 5.4) were randomized to 8-weekly sessions of MORE or a support group (SG) control condition. IGD severity, levels of craving for video game playing, maladaptive gaming-related cognitions, and positive reappraisal were measured at pre-and posttreatment, and 3-month follow-up. Results: Multivariate path analyses revealed that effects of MORE in reducing IGD and craving were statistically mediated by changes in maladaptive gaming-related cognitions. Though changes in positive reappraisal did not significantly mediate effects of MORE on IGD or craving, MORE enhanced positive reappraisal to a significantly greater extent than the SG at posttreatment. Discussion: Findings suggest that effects of mindfulness treatment in reducing maladaptive gaming-related cognitions might lead to reductions in IGD severity and cravings for video game playing. This cognitive mechanism should be evaluated in a future, full-scale RCT.

OBJECTIVE: Although opioid-treated chronic pain patients evidence blunted responsiveness to natural rewards, focusing on naturally rewarding stimuli can produce analgesia in these patients. A prior randomized controlled trial (RCT) demonstrated that a social work intervention-Mindfulness-Oriented Recovery Enhancement (MORE)-enhanced natural reward processing as indicated by event-related brain potentials (ERPs). The aim of the present study was to perform a secondary data analysis on ERPs collected in this RCT to explore whether improvements in electrocortical response to natural reward predicted pain relief. METHOD: The sample for this secondary analysis included opioid-treated chronic pain patients with complete ERP data (N = 29). Participants were randomized to 8 weeks of MORE or a support group control condition, and ERPs to images representing naturally rewarding stimuli were measured before and after 8 weeks of treatment. We explored associations between changes in brain reward response, chronic pain symptoms, and pain coping. RESULTS: Increases in ERP reward response were significantly associated with decreased pain severity from pretreatment to posttreatment (ß = -.48, p = .007) and improvements in pain catastrophizing (ß = -.36, p = .05) and diverting attention as a means of pain coping (ß = .38, p = .043). Increased ERP reward response predicted decreased pain interference by 3-month follow-up (ß = -.37, p = .048). CONCLUSIONS: Chronic pain may be alleviated by enhancing brain response to natural rewards.
RESUMO
Mindfulness-based interventions have been heralded as promising means of alleviating chronic stress. While meta-analyses indicate that mindfulness-based interventions significantly reduce global measures of stress, how mindfulness-based interventions modulate the specific mechanisms underpinning chronic stress as operationalized by the National Institute of Mental Health research domain criteria (RDoC) of sustained threat has not yet been detailed in the literature. To address this knowledge gap, this article aims to (1) review evidence that mindfulness-based interventions ameliorate each of the 10 elements of behavioral dysregulation characterizing sustained threat via an array of mindful counter-regulatory strategies; (2) review evidence that mindfulness-based interventions modify biological domains implicated in sustained threat, such as the hypothalamic-pituitary-adrenal axis, as well as brain circuits involved in attentional function, limbic reactivity, habit behavior, and the default mode network; and (3) integrate these findings into a novel conceptual framework of mindful self-regulation in the face of stress-the Mindfulness-to-Meaning Theory. Taken together, the extant body of scientific evidence suggests that the practice of mindfulness enhances a range biobehavioral factors implicated in adaptive stress coping and induces self-referential plasticity, leading to the ability to find meaning in adversity. These mechanistic findings can inform the treatment development process to optimize the next generation of mindfulness-based interventions for greater therapeutic efficacy.
RESUMO
Empirical studies have identified increasing rates of Internet gaming disorder (IGD) and associated adverse consequences. However, very few evidence-based interventions have been evaluated for IGD or problematic video gaming behaviors. This study evaluated Mindfulness-Oriented Recovery Enhancement (MORE) as a treatment for IGD. Thirty adults (Mage = 25.0, SD = 5.4) with IGD or problematic video gaming behaviors were randomized to 8 weeks of group-based MORE or 8 weeks of a support group (SG) control condition. Outcome measures were administered at pre- and posttreatment and 3-months following treatment completion using self-report instruments. Linear mixed models were used for outcome analyses. MORE participants had significantly greater reductions in the number of Diagnostic and Statistical Manual of Mental Disorders-5 IGD criteria they met, craving for video gaming, and maladaptive cognitions associated with gaming than SG participants, and therapeutic benefits were maintained at 3-month follow-up. MORE is a promising treatment approach for IGD. (PsycINFO Database Record

BACKGROUND: Given the risk of opioid misuse among chronic pain patients being treated with long-term opioid pharmacotherapy, non-pharmacological treatments are needed. Further, in light of hedonic deficits in this population, therapies that enhance positive affect may be useful. The purpose of this study was to examine effects of a Mindfulness-Oriented Recovery Enhancement (MORE) intervention on ecological momentary assessments (EMA) of pain and positive affective experience, and to determine if changes in pain, affect, and their interaction were associated with opioid misuse at post-treatment. METHODS: This study examined unpublished EMA data from a subset of participants (N=55) in a previously published RCT (NCT01505101) of MORE versus a support group (SG) control. Across 8 weeks of treatment, patients completed up to 224 EMA measures of pain and affect. Multilevel models and generalized estimating equations examined effects of treatment on momentary pain and positive affect, and generalized linear models examined associations between pain and affect and changes in opioid misuse by post-treatment. RESULTS: Patients in MORE reported significantly greater improvements in momentary pain (p=0.01) and positive affect (p=0.004) than patients in the SG. Further, over the entire course of treatment, patients in MORE were significantly more likely to exhibit positive affect regulation (OR=2.75) than patients in the SG. Finally, improvements in positive affect (but not pain) over the course of intervention were associated with reduced risk of misusing opioids by post-treatment (p=0.02). CONCLUSION: MORE may be a useful non-pharmacological treatment for pain and hedonic deficits among chronic pain patients at risk for opioid misuse.

High rates of relapse following substance misuse treatment highlight an urgent need for effective therapies. Although the number of empirical studies investigating effects of mindfulness treatment for substance misuse has increased dramatically in recent years, few reviews have examined findings of mindfulness studies. Thus, this systematic review examined methodological characteristics and substantive findings of studies evaluating mindfulness treatments for substance misuse published by 2015. The review also includes the first meta-analysis of randomized controlled trials of mindfulness treatments for substance misuse. Comprehensive bibliographic searches in PubMed, PsycInfo, and Web of Science, identified 42 pertinent studies. Meta-analytic results revealed significant small-to-large effects of mindfulness treatments in reducing the frequency and severity of substance misuse, intensity of craving for psychoactive substances, and severity of stress. Mindfulness treatments were also effective in increasing rates of posttreatment abstinence from cigarette smoking compared to alternative treatments. Mindfulness treatment for substance misuse is a promising intervention for substance misuse, although more research is needed examining the mechanisms by which mindfulness interventions exert their effects and the effectiveness of mindfulness treatments in diverse treatment settings.

Dysregulated processing of natural rewards may be a central pathogenic process in the etiology and maintenance of prescription opioid misuse and addiction among chronic pain patients. This study examined whether a Mindfulness-Oriented Recovery Enhancement (MORE) intervention could augment natural reward processing through training in savoring as indicated by event-related brain potentials (ERPs). Participants were chronic pain patients at risk for opioid misuse who were randomized to 8 weeks of MORE (n = 11) or a support group control condition (n = 18). ERPs to images representing naturally rewarding stimuli (e.g., beautiful landscapes, intimate couples) and neutral images were measured before and after 8 weeks of treatment. Analyses focused on the late positive potential (LPP)--an ERP response in the 400-1,000 ms time window thought to index allocation of attention to emotional information. Treatment with MORE was associated with significant increases in LPP response to natural reward stimuli relative to neutral stimuli which were correlated with enhanced positive affective cue-responses and reductions in opioid craving from pre- to post-treatment. Findings suggest that cognitive training regimens centered on strengthening attention to natural rewards may remediate reward processing deficits underpinning addictive behavior.

CONTEXT: Chronic pain impacts one-third of the U.S. population, and its effects are debilitating for individuals and costly to the medical system. Although opioids are commonly prescribed to address chronic pain, they confer risk for misuse and addiction in some patients and may not fully restore life function-particularly with regard to psychosocial factors. Because of the multiplicity of impacts that chronic pain may have on daily functioning, broad-spectrum behavioral interventions are needed. OBJECTIVES: The purpose of this study was to conduct follow-up analyses from a pilot randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE) to assess specific effects of MORE on various biopsychosocial aspects of pain-related impairment. METHODS: Chronic pain patients (N = 115; mean age, 48 ± 14 years; 68% female) were randomly assigned to either eight weeks of MORE or a support group. Domains of pain-related functional interference were measured with the Brief Pain Inventory at pre- and post-treatment and at a three-month follow-up. Treatment effects were analyzed with multivariate intention-to-treat models. RESULTS: MORE participants reported significantly greater reductions in functional interference than support group participants at post-treatment across all domains, including general activity, mood, walking ability, normal work, relationships, sleep, and enjoyment of life. These effects were largely maintained by the three-month follow-up; however, general activity level and walking ability were no longer significant, indicating differential long-term effects between physiological and psychological functioning. CONCLUSION: Findings demonstrate preliminary efficacy of MORE as a treatment for pain-related functional impairments and suggest that effects may be more pronounced and durable for aspects of psychological function.

RATIONALE: Dysregulated reward processing is a hallmark feature of drug addiction; however, scant research has evaluated restructuring reward processing in the context of addiction treatment. OBJECTIVES: We examined effects of Mindfulness-Oriented Recovery Enhancement (MORE) on reward responsiveness (RR) and opioid cue-reactivity in a sample of chronic pain patients with opioid use problems. We previously reported that MORE decreased pain, opioid misuse, and craving relative to a social support control group (SG). Here, we examined whether these outcomes were linked to changes in RR in a subset of participants. METHODS: Participants were chronic pain patients (71 % women, age 46.6 ± 13.9) who received MORE (n = 20) or SG (n = 29). RR was measured before and after 8 weeks of treatment via heart rate (HR) and heart rate variability (HRV) responses during a dot probe task that included opioid-related, pain-related, and natural reward stimuli, as well as craving ratings. RESULTS: The MORE group, who reported decreased opioid misuse and opioid craving during treatment, evidenced less subjective opioid cue-reactivity, greater HR decelerations, and greater increases in HRV to all cues after treatment compared to the SG; HR and HRV effects were most pronounced for natural reward cues. Within the MORE group, HR deceleration to natural reward cues was correlated with increased subjective arousal to the cues, whereas HR deceleration to opioid cues was correlated with decreased subjective arousal. Effects of MORE on craving were mediated by enhanced RR. CONCLUSIONS: Results suggest that during treatment with MORE, cardiac-autonomic responsiveness to non-drug reward increases, while reactivity to opioid reward decreases. Studies are needed to discern whether changes in RR were a result or a determinant of reductions in opioid misuse and craving. RR may play a role in addiction treatment.

OBJECTIVE: Opioid pharmacotherapy is now the leading treatment for chronic pain, a problem that affects nearly one third of the U.S. population. Given the dramatic rise in prescription opioid misuse and opioid-related mortality, novel behavioral interventions are needed. The purpose of this study was to conduct an early-stage randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE), a multimodal intervention designed to simultaneously target mechanisms underpinning chronic pain and opioid misuse. METHOD: Chronic pain patients (N = 115; mean age = 48 ± 14 years; 68% female) were randomized to 8 weeks of MORE or a support group (SG). Outcomes were measured at pre- and posttreatment, and at 3-month follow-up. The Brief Pain Inventory was used to assess changes in pain severity and interference. Changes in opioid use disorder status were measured by the Current Opioid Misuse Measure. Desire for opioids, stress, nonreactivity, reinterpretation of pain sensations, and reappraisal were also evaluated. RESULTS: MORE participants reported significantly greater reductions in pain severity (p = .038) and interference (p = .003) than SG participants, which were maintained by 3-month follow-up and mediated by increased nonreactivity and reinterpretation of pain sensations. Compared with SG participants, participants in MORE evidenced significantly less stress arousal (p = .034) and desire for opioids (p = .027), and were significantly more likely to no longer meet criteria for opioid use disorder immediately following treatment (p = .05); however, these effects were not sustained at follow-up. CONCLUSIONS: Findings demonstrate preliminary feasibility and efficacy of MORE as a treatment for co-occurring prescription opioid misuse and chronic pain.

Prominent neuroscience models suggest that addictive behavior occurs when environmental stressors and drug-relevant cues activate a cycle of cognitive, affective, and psychophysiological mechanisms, including dysregulated interactions between bottom-up and top-down neural processes, that compel the user to seek out and use drugs. Mindfulness-based interventions (MBIs) target pathogenic mechanisms of the risk chain linking stress and addiction. This review describes how MBIs may target neurocognitive mechanisms of addiction at the attention-appraisal-emotion interface. Empirical evidence is presented suggesting that MBIs ameliorate addiction by enhancing cognitive regulation of a number of key processes, including: clarifying cognitive appraisal and modulating negative emotions to reduce perseverative cognition and emotional arousal; enhancing metacognitive awareness to regulate drug-use action schema and decrease addiction attentional bias; promoting extinction learning to uncouple drug-use triggers from conditioned appetitive responses; reducing cue-reactivity and increasing cognitive control over craving; attenuating physiological stress reactivity through parasympathetic activation; and increasing savoring to restore natural reward processing. Treatment and research implications of our neurocognitive framework are presented. We conclude by offering a temporally sequenced description of neurocognitive processes targeted by MBIs through a hypothetical case study. Our neurocognitive framework has implications for the optimization of addiction treatment with MBIs.
RESUMO
BACKGROUND: Chronic pain involves hypervigilance for pain-related stimuli. Selective attention to pain-related stimuli, known as pain attentional bias (AB), can exacerbate chronic pain, prolong suffering, and undermine quality of life. The aim of this study was to determine if a multimodal mindfulness-oriented intervention could significantly reduce pain AB among chronic pain patients receiving opioid analgesics. METHODS: A total of 67 chronic pain patients were randomized to an 8-week Mindfulness-Oriented Recovery Enhancement (MORE) intervention or a social support group intervention and began treatment. A dot probe task was used to measure pain AB. Primary outcomes were pain AB scores for cues presented for 2,000 and 200 ms. RESULTS: Prior to intervention, participants exhibited a significant bias towards pain-related cues presented for 2,000 ms, but no bias for cues presented for 200 ms. A statistically significant time × intervention condition interaction was observed for 2,000 ms pain AB, such that participants in MORE evidenced significantly reduced posttreatment pain AB relative to pretreatment levels, whereas no significant pre-post treatment changes in pain AB were observed for support group participants. Decreases in pain AB were associated with increased perceived control over pain and attenuated reactivity to distressing thoughts and emotions. CONCLUSION: Study findings provide the first indication that a mindfulness-oriented intervention may reduce pain AB among adults suffering from chronic pain. Given the magnitude of chronic pain in postindustrial societies, coupled with the dramatic escalation in prescription opioid misuse, future studies should evaluate MORE as a nonpharmacological means of addressing factors linked with chronic pain.

Mindfulness-based interventions may decrease addictive behaviors while promoting non-reactivity to stressors. This study employed qualitative methods to enhance understanding of mindfulness-related treatment effects. Study participants were eighteen alcohol dependent adults residing in a therapeutic community who had participated in a Mindfulness-Oriented Recovery Enhancement (MORE) intervention. Interviews were conducted to elicit participant narratives. Responses to open-ended questions were analyzed using a grounded theory approach and the method of constant comparison. Narrative accounts suggested that MORE enhanced self-awareness while helping clients to cope more effectively with emotional distress and addictive impulses. MORE appears to be acceptable to participants and feasible to implement within a residential treatment setting. Mindfulness training may assist marginalized persons recover from addiction.
RESUMO
Although mindfulness has been linked with salutary clinical outcomes, less is known about its relation to cognitive mechanisms implicated in the onset and maintenance of alcohol dependence. Because trait mindfulness is associated with attentional control and emotion regulation, we hypothesized that trait mindfulness would be inversely associated with attentional bias towards visual alcohol cues. We tested this hypothesis in a sample of alcohol-dependent adults residing in a treatment facility, who completed questionnaires on trait mindfulness, craving, and stress, as well as a spatial cueing task designed to assess alcohol attentional bias. Recovering alcohol-dependent individuals high in trait mindfulness exhibited less alcohol attentional bias (AB), stress, and craving, and greater alcohol-related self-efficacy, than their counterparts low in trait mindfulness. Multiple linear regression analyses indicated that trait mindfulness was more predictive of alcohol AB than stress, craving, alcohol-related self-efficacy, time in treatment, or pre-treatment level of alcohol consumption. Identification of malleable traits that can offset automatic cognitive mechanisms implicated in addiction may prove to be crucial to treatment development efforts.
RESUMO
RATIONALE: Identification of malleable neurocognitive predictors of relapse among alcohol-dependent individuals is important for the optimization of health care delivery and clinical services. OBJECTIVES: Given that alcohol cue-reactivity can predict relapse, we evaluated cue-elicited high-frequency heart rate variability (HFHRV) and alcohol attentional bias (AB) as potential relapse risk indices. METHOD: Alcohol-dependent patients in long-term residential treatment who had participated in mindfulness-oriented therapy or an addiction support group completed a spatial cueing task as a measure of alcohol AB and an affect-modulated alcohol cue-reactivity protocol while HFHRV was assessed. RESULTS: Post-treatment HFHRV cue-reactivity and alcohol AB significantly predicted the occurrence and timing of relapse by 6-month follow-up, independent of treatment condition and after controlling for alcohol dependence severity. Alcohol-dependent patients who relapsed exhibited a significantly greater HFHRV reactivity to stress-primed alcohol cues than patients who did not relapse. CONCLUSIONS: Cue-elicited HFHRV and alcohol AB can presage relapse and may therefore hold promise as prognostic indicators in clinical settings.
