RESUMO

BACKGROUND: Opioid use among pregnant women has more than quadrupled over the past 20 years; however, comorbid risk factors such as emotion dysregulation confound the developmental consequences of prenatal opioid use. Maternal respiratory sinus arrhythmia (RSA) may help to disentangle the comorbid risk factors of prenatal emotion dysregulation and substance use and isolate their consequences on newborn neurobehavior. METHODS: We examined maternal RSA in response to a mild, infant-related stress task in pregnant people (N = 192; 30 on medications for opioid use disorder) recruited from hospitals and a specialty prenatal clinic for substance use disorder. RESULTS: Three latent profiles emerged based on maternal RSA reactivity. Mothers with RSA increasing (Profile 3; more nervous system dysregulation) had higher levels of emotion dysregulation than mothers with RSA decreasing (Profile 1; well-regulated nervous system responses) but were not more likely to use opioids. Additionally, RSA profiles were associated with newborn neurobehavior, including attention, regulation, handling, and arousal. CONCLUSIONS: Given the variability in opioid use across RSA profiles and profile associations with newborn neurodevelopment, future studies should examine protective factors in pregnant individuals using opioids who show more flexible RSA responses. IMPACT: Our study examined maternal psychophysiology and newborn outcomes in a unique population with high levels of emotion dysregulation and opioid use. Three profiles of maternal respiratory sinus arrythmia (RSA) reactivity were identified during pregnancy: decreasing, blunted, and increasing. The RSA increasing and blunted profiles were associated with higher emotion dysregulation than the decreasing profile. Most pregnant people on medications for opioid use disorder (65%) were grouped into the blunted profile, suggesting they might be more at risk for dysregulated RSA reactivity. Differences in RSA profiles were associated with newborn outcomes, with increasing and blunted RSA predicting more newborn neurobehavioral dysregulation.

RESUMO

The opioid crisis emerged in part due to the overprescribing of opioid analgesics for chronic pain. Although not the only source of the current epidemic of opioid use disorder (OUD), the prescription of opioids for chronic pain remains one vector for the development of opioid misuse and OUD. However, opioid tapering is not appropriate for all patients, and some patients may need to remain on opioid therapy for the long term. To reduce the risk of opioid-related harm among people with chronic pain and to treat incipient or entrenched addictive behaviours, new interventions are needed. This review discusses the clinical outcomes, biobehavioural mechanisms and implementation considerations for a novel, evidence-based intervention for chronic pain, opioid use and OUD called Mindfulness-Oriented Recovery Enhancement (MORE). MORE unites complementary aspects of mindfulness training, cognitive behavioural therapy and principles from positive psychology to simultaneously address addictive behaviour, emotion dysregulation and chronic pain by targeting brain reward and stress systems. MORE has been tested in 13 completed randomized clinical trials, including over 1300 patients, and has demonstrated efficacy against a range of active control conditions for reducing opioid dosing, opioid misuse, illicit drug use, depression, post-traumatic stress symptoms and chronic pain. Opportunities for implementing MORE include facilitating opioid tapering and promoting safe opioid use in primary care and specialty pain clinics, decreasing opioid misuse and enhancing medication-assisted treatment for OUD. Given evidence of MORE's efficacy, it is now time to consider disseminating this evidence-based treatment in the United States, the United Kingdom and worldwide.

RESUMO

BACKGROUND: Neuropsychopharmacologic effects of long-term opioid therapy (LTOT) in the context of chronic pain may result in subjective anhedonia coupled with decreased attention to natural rewards. Yet, there are no known efficacious treatments for anhedonia and reward deficits associated with chronic opioid use. Mindfulness-Oriented Recovery Enhancement (MORE), a novel behavioral intervention combining training in mindfulness with savoring of natural rewards, may hold promise for treating anhedonia in LTOT. METHODS: Veterans receiving LTOT (N = 63) for chronic pain were randomized to 8 weeks of MORE or a supportive group (SG) psychotherapy control. Before and after the 8-week treatment groups, we assessed the effects of MORE on the late positive potential (LPP) of the electroencephalogram and skin conductance level (SCL) during viewing and up-regulating responses (i.e. savoring) to natural reward cues. We then examined whether these neurophysiological effects were associated with reductions in subjective anhedonia by 4-month follow-up. RESULTS: Patients treated with MORE demonstrated significantly increased LPP and SCL to natural reward cues and greater decreases in subjective anhedonia relative to those in the SG. The effect of MORE on reducing anhedonia was statistically mediated by increases in LPP response during savoring. CONCLUSIONS: MORE enhances motivated attention to natural reward cues among chronic pain patients on LTOT, as evidenced by increased electrocortical and sympathetic nervous system responses. Given neurophysiological evidence of clinical target engagement, MORE may be an efficacious treatment for anhedonia among chronic opioid users, people with chronic pain, and those at risk for opioid use disorder.

RESUMO

BACKGROUND: Improving pain management for persons with chronic low back pain (LBP) undergoing surgery is an important consideration in improving patient-centered outcomes and reducing the risk of persistent opioid use after surgery. Nonpharmacological treatments, including physical therapy and mindfulness, are beneficial for nonsurgical LBP through complementary biopsychosocial mechanisms, but their integration and application for persons undergoing surgery for LBP have not been examined. This study (MIND-PT) is a multisite randomized trial that compares an enriched pain management (EPM) pathway that integrates physical therapy and mindfulness vs usual-care pain management (UC) for persons undergoing surgery for LBP. DESIGN: Participants from military treatment facilities will be enrolled before surgery and individually randomized to the EPM or UC pain management pathways. Participants assigned to EPM will receive presurgical biopsychosocial education and mindfulness instruction. After surgery, the EPM group will receive 10 sessions of physical therapy with integrated mindfulness techniques. Participants assigned to the UC group will receive usual pain management care after surgery. The primary outcome will be the pain impact, assessed with the Pain, Enjoyment, and General Activity (PEG) scale. Time to opioid discontinuation is the main secondary outcome. SUMMARY: This trial is part of the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative, which is focused on providing scientific solutions to the opioid crisis. The MIND-PT study will examine an innovative program combining nonpharmacological treatments designed to improve outcomes and reduce opioid overreliance in persons undergoing lumbar surgery.

RESUMO

Given the severity of the ongoing opioid epidemic, it is essential to understand the mechanisms of risk for development and maintenance of opioid use disorder (OUD). The aim of the current large-scale psychophysiological investigation was to test whether patients with OUD had lower resting-state high-frequency heart rate variability (HF-HRV) than those without OUD, controlling for sociodemographic and clinical confounds. Additionally, we tested whether HF-HRV was associated with opioid craving in this population. Participants in this cross-sectional study were 490 chronic pain patients (50.4% female) treated with long-term opioid therapy. OUD diagnosis was determined by psychiatric interview. HF-HRV was measured at resting baseline. We computed the association between OUD and resting-state HF-HRV, controlling for age, gender, race, pain severity, emotional distress and opioid dose. Opioid craving was measured with visual analogue scales to assess whether HF-HRV was associated with craving. Results showed that resting HF-HRV was significantly lower for patients with OUD than for those without OUD (p < 0.001, d = 0.36), indicating deficits in autonomic flexibility. OUD diagnosis (p = 0.002) and OUD severity (p = 0.03) were associated with lower HF-HRV in regression models accounting for a range of confounders. Additionally, lower HF-HRV was significantly (but weakly) correlated with heightened opioid craving (r = -0.166, p < 0.001). Overall, findings suggest that resting-state HF-HRV may serve as a valid biomarker of addiction among people on long-term opioid therapy.

RESUMO

Background: Modeling addictive behavior among individuals with, or at risk for, opioid use disorder (OUD) in a way that is accurate, ethical, and reproducible presents a pressing concern. OUD risk is elevated among people with chronic pain on long-term opioid therapy (LTOT).Objectives: To provide initial validation of a novel opioid preference task as an index of OUD and its symptomatology among veterans prescribed opioids for chronic pain, a population at high risk for poor opioid-related outcomes. The relative ease by which such a paradigm can be implemented and performed in clinical contexts, including enabling investigation of opioid reinforcement and drug-seeking behavior while avoiding ethical pitfalls associated with direct drug administration, could make this task an attractive approach for potentially tracking OUD symptoms.Methods: We studied 87 veterans (74 males, 13 females) on LTOT for chronic pain - 33 of whom had OUD diagnoses. Participants completed a picture-viewing choice task to assess preference for viewing opioid-related images in comparison with standardized pleasant, unpleasant, neutral, and blank images. Opioid-related choice, measured by vigor of button pressing, was tested for association with OUD severity (measured by symptom counts), as well as craving and anhedonia.Results: Choice for opioid-related images was positively correlated with OUD severity (i.e., number of DSM-5 measured OUD symptoms) (r = 0.38, p < .001), particularly among those meeting diagnostic criteria for OUD (r = 0.47, p = .006). Neither craving nor anhedonia correlated with opioid-related choice.Conclusions: Our results provide initial validation for a new opioid picture-choice paradigm in patients with chronic pain.

RESUMO

BACKGROUND: Both acute and chronic pain can disrupt reward processing. Moreover, prolonged prescription opioid use and depressed mood are common in chronic pain samples. Despite the prevalence of these risk factors for anhedonia, little is known about anhedonia in chronic pain populations. METHODS: We conducted a large-scale, systematic study of anhedonia in chronic pain, focusing on its relationship with opioid use/misuse, pain severity, and depression. Chronic pain patients across four distinct samples (N = 488) completed the Snaith-Hamilton Pleasure Scale (SHAPS), measures of opioid use, pain severity and depression, as well as the Current Opioid Misuse Measure (COMM). We used a meta-analytic approach to determine reference levels of anhedonia in healthy samples spanning a variety of countries and diverse age groups, extracting SHAPS scores from 58 published studies totaling 2664 psychiatrically healthy participants. RESULTS: Compared to healthy samples, chronic pain patients showed higher levels of anhedonia, with ~25% of patients scoring above the standard anhedonia cut-off. This difference was not primarily driven by depression levels, which explained less than 25% of variance in anhedonia scores. Neither opioid use duration, dose, nor pain severity alone was significantly associated with anhedonia. Yet, there was a clear effect of opioid misuse, with opioid misusers (COMM ⩾13) reporting greater anhedonia than non-misusers. Opioid misuse remained a significant predictor of anhedonia even after controlling for pain severity, depression and opioid dose. CONCLUSIONS: Study results suggest that both chronic pain and opioid misuse contribute to anhedonia, which may, in turn, drive further pain and misuse.

RESUMO

BACKGROUND: The USA is currently enduring an opioid crisis. Identifying cost-effective, easy-to-implement behavioral measures that predict treatment outcomes in opioid misusers is a crucial scientific, therapeutic, and epidemiological goal. METHODS: The current study used a mixed cross-sectional and longitudinal design to test whether a behavioral choice task, previously validated in stimulant users, was associated with increased opioid misuse severity at baseline, and whether it predicted change in opioid misuse severity at follow-up. At baseline, data from 100 prescription opioid-treated chronic pain patients were analyzed; at follow-up, data were analyzed in 34 of these participants who were non-misusers at baseline. During the choice task, participants chose under probabilistic contingencies whether to view opioid-related images in comparison with affectively pleasant, unpleasant, and neutral images. Following previous procedures, we also assessed insight into choice behavior, operationalized as whether (yes/no) participants correctly self-reported the image category they chose most often. RESULTS: At baseline, the higher choice for viewing opioid images in direct comparison with pleasant images was associated with opioid misuse and impaired insight into choice behavior; the combination of these produced especially elevated opioid-related choice behavior. In longitudinal analyses of individuals who were initially non-misusers, higher baseline opioid v. pleasant choice behavior predicted more opioid misuse behaviors at follow-up. CONCLUSIONS: These results indicate that greater relative allocation of behavior toward opioid stimuli and away from stimuli depicting natural reinforcement is associated with concurrent opioid misuse and portends vulnerability toward future misuse. The choice task may provide important medical information to guide opioid-prescribing practices.

RESUMO

BACKGROUND: The Defense Health Agency has prioritized system-level pain management initiatives within the Military Health System (MHS), with low back pain as one of the key focus areas. A stepped care model focused on nonpharmacologic treatment to promote self-management is recommended. Implementation of stepped care is complicated by lack of information on the most effective nonpharmacologic strategies and how to sequence and tailor the various available options. The Sequential Multiple-Assignment Randomization Trial for Low Back Pain (SMART LBP) is a multisite pragmatic trial using a SMART design to assess the effectiveness of nonpharmacologic treatments for chronic low back pain. DESIGN: This SMART trial has two treatment phases. Participants from three military treatment facilities are randomized to 6 weeks of phase I treatment, receiving either physical therapy (PT) or Army Medicine's holistic Move2Health (M2H) program in a package specific to low back pain. Nonresponders to treatment in phase I are again randomized to phase II treatment of combined M2H + PT or mindfulness-based treatment using the Mindfulness-Oriented Recovery Enhancement (MORE) program. The primary outcome is the Patient-Reported Outcomes Measurement Information System pain interference computer-adapted test score. SUMMARY: This trial is part of an initiative funded by the National Institutes of Health, Veterans Affairs, and the Department of Defense to establish a national infrastructure for effective system-level management of chronic pain with a focus on nonpharmacologic treatments. The results of this study will provide important information on nonpharmacologic care for chronic LBP in the MHS embedded within a stepped care framework.

RESUMO

Preclinical studies have shown effects of chronic exposure to addictive drugs on glutamatergic-mediated neuroplasticity in frontostriatal circuitry. These initial findings have been paralleled by human functional magnetic resonance imaging (fMRI) research demonstrating weaker frontostriatal resting-state functional connectivity (rsFC) among individuals with psychostimulant use disorders. However, there is a dearth of human imaging literature describing associations between long-term prescription opioid use, frontostriatal rsFC, and brain morphology among chronic pain patients. We hypothesized that prescription opioid users with chronic pain, as compared with healthy control subjects, would evidence weaker frontostriatal rsFC coupled with less frontostriatal gray matter volume (GMV). Further, those opioid use-related deficits in frontostriatal circuitry would be associated with negative affect and drug misuse. Prescription opioid users with chronic pain (n = 31) and drug-free healthy controls (n = 30) underwent a high-resolution anatomical and an eyes-closed resting-state functional scan. The opioid group, relative to controls, exhibited weaker frontostriatal rsFC, and less frontostriatal GMV in both L.NAc and L.vmPFC. Frontostriatal rsFC partially mediated group differences in negative affect. Within opioid users, L.NAc GMV predicted opioid misuse severity. The current study revealed that prescription opioid use in the context of chronic pain is associated with functional and structural abnormalities in frontostriatal circuitry. These results suggest that opioid use-related abnormalities in frontostriatal circuitry may undergird disturbances in affect that may contribute to the ongoing maintenance of opioid use and misuse. These findings warrant further examination of interventions to treat opioid pathophysiology in frontostriatal circuitry over the course of treatment.

RESUMO

BACKGROUND: Low back pain is a prevalent condition that causes a substantial health burden. Despite intensive and expensive clinical efforts, its prevalence is growing. Nonpharmacologic treatments are effective at improving pain-related outcomes; however, treatment effect sizes are often modest. Physical therapy (PT) and cognitive behavioral therapy (CBT) have the most consistent evidence of effectiveness. Growing evidence also supports mindfulness-based approaches. Discussions with providers and patients highlight the importance of discussing and trying options to find the treatment that works for them and determining what to do when initial treatment is not successful. Herein, we present the protocol for a study that will evaluate evidence-based, protocol-driven treatments using PT, CBT, or mindfulness to examine comparative effectiveness and optimal sequencing for patients with chronic low back pain. METHODS: The Optimized Multidisciplinary Treatment Programs for Nonspecific Chronic Low Back Pain (OPTIMIZE) Study will be a multisite, comparative effectiveness trial using a sequential multiple assessment randomized trial design enrolling 945 individuals with chronic low back pain. The co-primary outcomes will be disability (measured using the Oswestry Disability Index) and pain intensity (measured using the Numerical Pain Rating Scale). After baseline assessment, participants will be randomly assigned to PT or CBT. At week 10, participants who have not experienced at least 50% improvement in disability will be randomized to cross-over phase-1 treatments (e.g., PT to CBT) or to Mindfulness-Oriented Recovery Enhancement (MORE). Treatment will consist of 8 weekly sessions. Long-term outcome assessments will be performed at weeks 26 and 52. DISCUSSION: Results of this study may inform referring providers and patients about the most effective nonoperative treatment and/or sequence of nonoperative treatments to treat chronic low back pain. TRIAL REGISTRATION: This study was prospectively registered on March 1, 2019, with Clinicaltrials.gov under the registration number NCT03859713 (https://clinicaltrials.gov/ct2/show/NCT03859713).

RESUMO

OBJECTIVE: Mindfulness-based interventions target novel pain relief mechanisms not captured by legacy pain scales, including 1) cultivating awareness of pleasant and neutral sensations proximal to unpleasant sensations and 2) interoceptively mapping sensation location and spatial distribution. METHODS: We created a digital sensation manikin (SM) by overlaying a human figure silhouette with a grid of 469 "sensation" pixels. A series of five research questions examined the SM's discriminant validity, construct validity, incremental validity, convergence with an objective measure of pain attentional bias, and sensitivity to a mindfulness-based psychological treatment, Mindfulness-Oriented Recovery Enhancement (MORE). A sample of opioid treated chronic pain patients (n = 108; age, 53.79 (12.94) years; female, 65%) was recruited to answer research questions 1 to 5, and a sample of healthy controls (n = 91; age, 36.47 (13.50) years; female, 55%) was recruited as the comparison group for research question 1. RESULTS: Chronic pain patients reported significantly more unpleasant sensations than did healthy controls (p < .001, d = 1.23) and significantly fewer pleasant sensations (p = .001, d = 0.50). The SM also evidenced expected relationships with multiple measures of pain (r = 0.26-0.29) and well-being (r = -0.21 to 0.28), uniquely predicted pain interference (ß = -0.18), and exhibited a significant association with pain attentional bias (r = 0.25). Finally, mindfulness-based intervention via MORE significantly increased the ratio of pleasant to unpleasant sensations reported by chronic pain patients relative to an active control condition (p = .036, d = 0.51). CONCLUSIONS: This study supports the SM's validity and indicates that assessing both pleasant and unpleasant sensations broadens the scope of pain measurement. Although the SM would benefit from further optimization, its continued use is likely to contribute to improved assessment and treatment options for chronic pain patients.

RESUMO

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.

RESUMO

Through autonomic and affective mechanisms, adverse childhood experiences (ACEs) may disrupt the capacity to regulate negative emotions, increasing craving and exacerbating risk for opioid use disorder (OUD) among individuals with chronic pain who are receiving long-term opioid analgesic pharmacotherapy. This study examined associations between ACEs, heart rate variability (HRV) during emotion regulation, and negative emotional cue-elicited craving among a sample of female opioid-treated chronic pain patients at risk for OUD. A sample of women (N = 36, mean age = 51.2 ± 9.5) with chronic pain receiving long-term opioid analgesic pharmacotherapy (mean morphine equivalent daily dose = 87.1 ± 106.9 mg) were recruited from primary care and pain clinics to complete a randomized task in which they viewed and reappraised negative affective stimuli while HRV and craving were assessed. Both ACEs and duration of opioid use significantly predicted blunted HRV during negative emotion regulation and increased negative emotional cue-elicited craving. Analysis of study findings from a multiple-levels-of-analysis approach suggest that exposure to childhood abuse occasions later emotion dysregulation and appetitive responding toward opioids in negative affective contexts among adult women with chronic pain, and thus this vulnerable clinical population should be assessed for OUD risk when initiating a course of extended, high-dose opioids for pain management.

RESUMO

BACKGROUND: Medical management of acute pain among hospital inpatients may be enhanced by mind-body interventions. OBJECTIVE: We hypothesized that a single, scripted session of mindfulness training focused on acceptance of pain or hypnotic suggestion focused on changing pain sensations through imagery would significantly reduce acute pain intensity and unpleasantness compared to a psychoeducation pain coping control. We also hypothesized that mindfulness and suggestion would produce significant improvements in secondary outcomes including relaxation, pleasant body sensations, anxiety, and desire for opioids, compared to the control condition. METHODS: This three-arm, parallel-group randomized controlled trial conducted at a university-based hospital examined the acute effects of 15-min psychosocial interventions (mindfulness, hypnotic suggestion, psychoeducation) on adult inpatients reporting "intolerable pain" or "inadequate pain control." Participants (N = 244) were assigned to one of three intervention conditions: mindfulness (n = 86), suggestion (n = 73), or psychoeducation (n = 85). KEY RESULTS: Participants in the mind-body interventions reported significantly lower baseline-adjusted pain intensity post-intervention than those assigned to psychoeducation (p < 0.001, percentage pain reduction: mindfulness = 23%, suggestion = 29%, education = 9%), and lower baseline-adjusted pain unpleasantness (p < 0.001). Intervention conditions differed significantly with regard to relaxation (p < 0.001), pleasurable body sensations (p = 0.001), and desire for opioids (p = 0.015), but all three interventions were associated with a significant reduction in anxiety (p < 0.001). CONCLUSIONS: Brief, single-session mind-body interventions delivered by hospital social workers led to clinically significant improvements in pain and related outcomes, suggesting that such interventions may be useful adjuncts to medical pain management.

RESUMO

BACKGROUND: Research indicates that dispositional mindfulness is associated with positive psychological functioning. Although this disposition has been linked with beneficial outcomes in the broader mental health literature, less is known about dispositional mindfulness in cancer survivors and how it may be linked with indices of psychological and physical health relevant to cancer survivorship. METHODS: We conducted a multivariate path analysis of data from a heterogeneous sample of cancer patients (N = 97) to test the Mindfulness-to-Meaning Theory, an extended process model of emotion regulation linking dispositional mindfulness with cancer-related quality of life via positive psychological processes. RESULTS: We found that patients endorsing higher levels of dispositional mindfulness were more likely to pay attention to positive experiences (ß = .56), a tendency which was associated with positive reappraisal of stressful life events (ß = .51). Patients who engaged in more frequent positive reappraisal had a greater sense of meaning in life (ß = .43) and tended to savor rewarding or life affirming events (ß = .50). In turn, those who engaged in high levels of savoring had better quality of life (ß = .33) and suffered less from emotional distress (ß = -.54). CONCLUSIONS: Findings provide support for the Mindfulness-to-Meaning Theory and help explicate the processes by which mindfulness promotes psychological flourishing in the face of cancer. IMPLICATIONS FOR CANCER SURVIVORSHIP: Cancer survivors may benefit from enhancing mindfulness, reappraisal, and savoring. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

The association between mindfulness and selflessness is firmly grounded in classical Indo-Sino-Tibetan contemplative traditions, but has received limited empirical attention from Western researchers. In Buddhism, the relationship between mindfulness and the self is of central concern to the cultivation of well-being. Mindfulness is believed to encourage insight into the truly insubstantial nature of the self, an understanding that is thought to encourage well-being. The present study explores these relationships, attending to dispositional mindfulness, the self as it exists on a continuum from self-centered to selfless, and psychological well-being. Results indicate a positive relationship between selflessness, dispositional mindfulness, and psychological well-being. It appears that construing the self as interdependent and interconnected with a broader social, natural, and cosmic context is linked with greater psychological well-being and dispositional mindfulness. Path analyses revealed that selflessness mediated the relationship between dispositional mindfulness and psychological well-being.

RESUMO

Emerging research suggests that prescription opioid craving is associated with negative mood and depression, but less is known about cognitive factors linking depressive symptoms to opioid craving among adults with chronic pain. The present cross-sectional study examined thought suppression as a mediator of the relation between depression and prescription opioid craving in a sample of chronic pain patients receiving long-term opioid pharmacotherapy. Data were obtained from 115 chronic pain patients recruited from primary care, pain, and neurology clinics who had taken prescription opioids daily or nearly every day for ≥90 days prior to assessment. In this sample, 60 % of participants met DSM-IV criteria for current major depressive disorder. Depressed mood (r = .36, p < .001) and thought suppression (r = .33, p < .001) were significantly correlated with opioid craving. Multivariate path analyses with bootstrapping indicated the presence of a significant indirect effect of thought suppression on the association between depressed mood and opioid craving (indirect effect = .09, 95 % CI .01, .20). Sensitivity analyses showed a similar indirect effect of suppression linking major depressive disorder diagnosis and opioid craving. Attempts to suppress distressing and intrusive thoughts may result in increased craving to use opioids among chronic pain patients with depressive symptoms. Results highlight the need for interventions that mitigate thought suppression among adults with pain and mood disorders.

RESUMO

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.
