RESUMEN

OBJECTIVE: This randomized clinical trial evaluated the efficacy of Mindfulness-Oriented Recovery Enhancement (MORE) among past and present U.S. military personnel with prescriptions for long-term opioid therapy for chronic pain. METHODS: In this clinical trial, 230 past and present military personnel with prescriptions for long-term opioid therapy were randomized in a 1:1 ratio to MORE or supportive psychotherapy (initially delivered in person and then via videoconferencing after the onset of the COVID-19 pandemic). Primary outcomes were chronic pain, measured by the Brief Pain Inventory, and aberrant drug-related behaviors, measured by the Current Opioid Misuse Measure, through 8 months of follow-up. Opioid dose was a key secondary outcome. Other outcomes included psychiatric symptoms, catastrophizing, positive affect, ecological momentary assessments of opioid craving, and opioid attentional bias. RESULTS: MORE was superior to supportive psychotherapy through the 8-month follow-up in reducing pain-related functional interference, pain severity, and opioid dose. MORE reduced daily opioid dose by 20.7%, compared with a dose reduction of 3.9% with supportive psychotherapy. Although there was no overall between-group difference in opioid misuse, the in-person MORE intervention outperformed supportive psychotherapy for reducing opioid misuse. MORE reduced anhedonia, pain catastrophizing, craving, and opioid attentional bias and increased positive affect to a greater extent than supportive psychotherapy. MORE also modulated therapeutic processes, including mindful reinterpretation of pain sensations, nonreactivity, savoring, positive attention, and reappraisal. CONCLUSIONS: Among past and present U.S. military personnel, MORE led to sustained decreases in chronic pain, opioid use, craving, and opioid cue reactivity. MORE facilitated opioid dose reduction while preserving adequate pain control and preventing mood disturbances, suggesting its utility for safe opioid tapering.

RESUMEN

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.

RESUMEN

IMPORTANCE: Successful treatment of opioid misuse among people with chronic pain has proven elusive. Guidelines recommend nonopioid therapies, but the efficacy of mindfulness-based interventions for opioid misuse is uncertain. OBJECTIVE: To evaluate the efficacy of Mindfulness-Oriented Recovery Enhancement (MORE) for the reduction of opioid misuse and chronic pain. DESIGN, SETTING, AND PARTICIPANTS: This interviewer-blinded randomized clinical trial enrolled patients from primary care clinics in Utah between January 4, 2016, and January 16, 2020. The study included 250 adults with chronic pain receiving long-term opioid therapy who were misusing opioid medications. INTERVENTIONS: Treatment with MORE (comprising training in mindfulness, reappraisal, and savoring positive experiences) or supportive group psychotherapy (control condition) across 8 weekly 2-hour group sessions. MAIN OUTCOMES AND MEASURES: Primary outcomes were (1) opioid misuse assessed by the Drug Misuse Index (self-report, interview, and urine screen) and (2) pain severity and pain-related functional interference, assessed by subscale scores on the Brief Pain Inventory through 9 months of follow-up. Secondary outcomes were opioid dose, emotional distress, and ecological momentary assessments of opioid craving. The minimum intervention dose was defined as 4 or more completed sessions of MORE or supportive group psychotherapy. RESULTS: Among 250 participants (159 women [63.6%]; mean [SD] age, 51.8 [11.9] years), 129 were randomized to the MORE group and 121 to the supportive psychotherapy group. Overall, 17 participants (6.8%) were Hispanic or Latino, 218 (87.2%) were White, and 15 (6.0%) were of other races and/or ethnicities (2 American Indian, 3 Asian, 1 Black, 2 Pacific Islander, and 7 did not specify). At baseline, the mean duration of pain was 14.7 years (range, 1-60 years), and the mean (SD) morphine-equivalent opioid dose was 101.0 (266.3) mg (IQR, 16.0-90.0 mg). A total of 203 participants (81.2%) received the minimum intervention dose (mean [SD], 5.7 [2.2] sessions); at 9 months, 92 of 250 participants (36.8%) discontinued the study. The overall odds ratio for reduction in opioid misuse through the 9-month follow-up period in the MORE group compared with the supportive psychotherapy group was 2.06 (95% CI, 1.17-3.61; P = .01). At 9 months, 36 of 80 participants (45.0%) in the MORE group were no longer misusing opioids compared with 19 of 78 participants (24.4%) in the supportive psychotherapy group. Mixed models demonstrated that MORE was superior to supportive psychotherapy through 9 months of follow-up for pain severity (between-group effect: 0.49; 95% CI, 0.17-0.81; P = .003) and pain-related functional interference (between-group effect: 1.07; 95% CI, 0.64-1.50; P < .001). Participants in the MORE group reduced their opioid dose to a greater extent than those in the supportive psychotherapy group. The MORE group also had lower emotional distress and opioid craving. CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, among adult participants in a primary care setting, the MORE intervention led to sustained improvements in opioid misuse and chronic pain symptoms and reductions in opioid dosing, emotional distress, and opioid craving compared with supportive group psychotherapy. Despite attrition caused by the COVID-19 pandemic and the vulnerability of the sample, MORE appeared to be efficacious for reducing opioid misuse among adults with chronic pain.

RESUMEN

OBJECTIVE: Mind-Body Bridging (MBB) has been shown to be effective for improving disturbed sleep. In this prospective randomized controlled trial, we evaluated the efficacy of sleep-focused MBB compared with sleep education control (SED) for improving sleep in previously deployed Gulf War veterans. METHODS: US military service members with sleep and physical health complaints who were deployed in 1990-1991 were randomized to receive three weekly sessions of either MBB (n = 33) or SED (n = 27) between 2012 and 2015. The primary outcome of Medical Outcomes Study Sleep Scale was completed at baseline, weekly during treatment, postintervention, and 3-month follow-up. Secondary outcome measures for posttraumatic stress disorder, depression, fatigue, quality of life, symptom severity, and mindfulness were completed at baseline, postintervention and 3-month follow-up. Salivary samples were collected at five time points per day at each visit for cortisol and α-amylase assessment. Clinician-administered assessments of sleep and co-occurring conditions were conducted at baseline and postintervention. RESULTS: MBB was significantly more efficacious than SED in reducing disturbed sleep at follow-up (F(1,180.54) = 4.04, p = .046). In addition, self-reported posttraumatic stress disorder (F(1,56.42) = 4.50, p = .038) for the treatment effect, depression (F(1,93.70) = 4.44, p = .038), and fatigue symptoms (F(1,68.58) = 3.90, p = .050) at follow-up improved in MBB compared with those in SED. Consistently higher percentages of veterans in MBB reported improvements of sleep, pain, and composite sleep/general co-occurring symptoms at the postclinical evaluation, as compared with veterans in SED. Finally, the mean waking level of salivary α-amylase in the MBB declined to a greater extent than that in the SED, at follow-up (F(1,88.99) = 3.78, p = .055), whereas no effects were found on cortisol. CONCLUSIONS: Sleep-focused MBB can improve sleep and possibly also co-occurring symptoms in Gulf War veterans. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov, NCT01543997.

RESUMEN

Cancer survivors experience high levels of distress, associated with a host of negative psychological states, including anxiety, depression, and fear of recurrence, which often lead to sleep problems and reduction in quality of life (QOL) and well-being. As a neuropeptide hormone associated with affiliation, calmness, and well-being, oxytocin may be a useful biological measure of changes in health outcomes in cancer survivors. In this exploratory study, which comprised a subset of participants from a larger study, we evaluated (a) the feasibility and reliability of salivary oxytocin (sOT) levels in cancer survivors and (b) the effects of 2 sleep-focused mind-body interventions, mind-body bridging (MBB) and mindfulness meditation (MM), compared with a sleep hygiene education (SHE) control, on changes in sOT levels in 30 cancer survivors with self-reported sleep disturbance. Interventions were conducted in 3 sessions, once per week for 3 weeks. Saliva samples were collected at baseline, postintervention (~1 week after the last session), and at the 2-month follow-up. In this cancer survivor group, we found that intra-individual sOT levels were fairly stable across the 3 time points, of about 3 months' duration, and mean baseline sOT levels did not differ between females and males and were not correlated with age. Correlations between baseline sOT and self-report measures were weak; however, several of these relationships were in the predicted direction, in which sOT levels were negatively associated with sleep problems and depression and positively associated with cancer-related QOL and well-being. Regarding intervention effects on sOT, baseline-subtracted sOT levels were significantly larger at postintervention in the MBB group as compared with those in SHE. In this sample of cancer survivors assessed for sOT, at postintervention, greater reductions in sleep problems were noted for MBB and MM compared with that of SHE, and increases in mindfulness and self-compassion were observed in the MBB group compared with those in SHE. The findings in this exploratory study suggest that sOT may be a reliable biological measure over time that may provide insight into the effects of mind-body interventions on health outcomes in cancer survivors.

RESUMEN

OBJECTIVE: The main aim of this exploratory study was to assess whether salivary α-amylase (sAA) and salivary cortisol levels would be positively modulated by sleep-focused mind-body interventions in female and male cancer survivors. METHODS: We conducted a randomized controlled trial in which 57 cancer survivors with self-reported sleep disturbance received either a Sleep Hygiene Education (SHE; n=18) control, or one of two experimental mind-body interventions, namely, Mind-Body Bridging (MBB; n=19) or Mindfulness Meditation (MM; n=20). Interventions were three sessions each conducted once per week for three consecutive weeks. Saliva cortisol and sAA were measured at baseline and 1 week after the last session. Participants also completed a sleep scale at the same time points when saliva was collected for biomarker measurement. RESULTS: Our study revealed that at post-intervention assessment, mean sAA levels upon awakening ("Waking" sample) declined in MBB compared with that of SHE. Mean Waking cortisol levels did not differ among treatment groups but declined slightly in SHE. Self-reported sleep improved across the three interventions at Post-assessment, with largest improvements in the MBB intervention. CONCLUSION: In this exploratory study, sleep focused mind-body intervention (MBB) attenuated Waking sAA levels, suggesting positive influences of a mind-body intervention on sympathetic activity in cancer survivors with sleep disturbance.

RESUMEN

PURPOSE: After completing treatment, cancer survivors may suffer from a multitude of physical and mental health impairments, resulting in compromised quality of life. This exploratory study investigated whether two mind-body interventions, i.e., Mind-Body Bridging (MBB) and Mindfulness Meditation (MM), could improve posttreatment cancer survivors' self-reported sleep disturbance and comorbid symptoms, as compared to sleep hygiene education (SHE) as an active control. METHODS: This randomized controlled trial examined 57 cancer survivors with clinically significant self-reported sleep disturbance, randomly assigned to receive MBB, MM, or SHE. All interventions were conducted in three sessions, once per week. Patient-reported outcomes were assessed via the Medical Outcomes Study Sleep Scale and other indicators of psychosocial functioning relevant to quality of life, stress, depression, mindfulness, self-compassion, and well-being. RESULTS: Mixed effects model analysis revealed that mean sleep disturbance symptoms in the MBB (p = .0029) and MM (p = .0499) groups were lower than in the SHE group, indicating that both mind-body interventions improved sleep. In addition, compared with the SHE group, the MBB group showed reductions in self-reported depression symptoms (p = .040) and improvements in overall levels of mindfulness (p = .018), self-compassion (p = .028), and well-being (p = .019) at postintervention. CONCLUSIONS: This study provides preliminary evidence that brief sleep-focused MBB and MM are promising interventions for sleep disturbance in cancer survivors. Integrating MBB or MM into posttreatment supportive plans should enhance care of cancer survivors with sleep disturbance. Because MBB produced additional secondary benefits, MBB may serve as a promising multipurpose intervention for posttreatment cancer survivors suffering from sleep disturbance and other comorbid symptoms. IMPLICATIONS FOR CANCER SURVIVORS: Two brief sleep-focused mind-body interventions investigated in the study were effective in reducing sleep disturbance and one of them further improved other psychosocial aspects of the cancer survivors' life. Management of sleep problems in survivors is a high priority issue that demands more attention in cancer survivorship.

RESUMEN

BACKGROUND: Uncertainty about potentially painful events affects how pain is experienced. Individuals with fibromyalgia (FM) often exhibit anxiety and catastrophic thoughts regarding pain and difficulties dealing with pain uncertainty. OBJECTIVES: The effects of pain uncertainty in predictably high odds (HO), predictably low odds (LO), and even odds (EO) conditions on subjective ratings of pain (PR) and skin conductance responses (SCR) following the administration of a painful stimulus were examined for individuals with fibromyalgia (IWFM), healthy volunteers (HVs), and yoga practitioners (YPs). We hypothesized IWFM would demonstrate the greatest physiological reactivity to pain uncertainty, followed by HVs and YPs, respectively. METHODS: Nine IWFM, 7 YPs, and 10 HVs participated. RESULTS: Custom contrast estimates comparing responses for HO, LO, and EO pain conditions showed higher SCR for IWFM (CE = 1.27, p = 0.01) but not for HVs or for YPs. PR for the EO condition were significantly greater than for HO and LO conditions for IWFM (CE = 0.60, p = 0.012) but not for HVs or YPs. YPs had lower SCR and PR than did HVs. CONCLUSIONS: Results show that uncertainty regarding pain increases the experience of pain, whereas certainty regarding pain may reduce pain ratings for individuals with fibromyalgia.

RESUMEN

The defense response theory implies that individuals should respond to increasing levels of painful stimulation with correlated increases in affectively mediated psychophysiological responses. This paper employs structural equation modeling to infer the latent processes responsible for correlated growth in the pain report, evoked potential amplitudes, pupil dilation, and skin conductance of 92 normal volunteers who experienced 144 trials of three levels of increasingly painful electrical stimulation. The analysis assumed a two-level model of latent growth as a function of stimulus level. The first level of analysis formulated a nonlinear growth model for each response measure, and allowed intercorrelations among the parameters of these models across individuals. The second level of analysis posited latent process factors to account for these intercorrelations. The best-fitting parsimonious model suggests that two latent processes account for the correlations. One of these latent factors, the activation threshold, determines the initial threshold response, while the other, the response gradient, indicates the magnitude of the coherent increase in response with stimulus level. Collectively, these two second-order factors define the defense response, a broad construct comprising both subjective pain evaluation and physiological mechanisms.

RESUMEN

Few controlled clinical trials of psychological interventions for cancer pain relief exist in spite of frequent support for their importance as adjuncts to medical treatment. This study compared oral mucositis pain levels in 4 groups of cancer patients receiving bone marrow transplants (BMT): (1) treatment as usual control, (2) therapist support, (3) relaxation and imagery training, and (4) training in a package of cognitive-behavioral coping skills which included relaxation and imagery. A total of 94 patients completed the study which involved two training sessions prior to treatment and twice a week 'booster' sessions during the first 5 weeks of treatment. Results confirmed our hypothesis that patients who received either relaxation and imagery alone or patients who received the package of cognitive-behavioral coping skills would report less pain than patients in the other 2 groups. The hypothesis that the cognitive-behavioral skills package would have an additive effect beyond relaxation and imagery alone was not confirmed. Average visual analogue scale (VAS) report of pain within the therapist support group was not significantly lower than the control group (P = 0.103) nor significantly higher than the training groups. Patient reports of relative helpfulness of the interventions for managing pain and nausea matched the results of VAS reports. From these results, we conclude that relaxation and imagery training reduces cancer treatment-related pain; adding cognitive-behavioral skills to the relaxation with imagery does not, on average, further improve pain relief.

RESUMEN

Few controlled clinical trials have tested the efficacy of psychological techniques for reducing cancer pain or post-chemotherapy nausea and emesis. In this study, 67 bone marrow transplant patients with hematological malignancies were randomly assigned to one of four groups prior to beginning transplantation conditioning: (1) hypnosis training (HYP); (2) cognitive behavioral coping skills training (CB); (3) therapist contact control (TC); or (4) treatment as usual (TAU; no treatment control). Patients completed measures of physical functioning (Sickness Impact Profile; SIP) and psychological functioning (Brief Symptom Inventory; BSI), which were used as covariates in the analyses. Biodemographic variables included gender, age and a risk variable based on diagnosis and number of remissions or relapses. Patients in the HYP, CB and TC groups met with a clinical psychologist for two pre-transplant training sessions and ten in-hospital "booster" sessions during the course of transplantation. Forty-five patients completed the study and provided all covariate data, and 80% of the time series outcome data. Analyses of the principal study variables indicated that hypnosis was effective in reducing reported oral pain for patients undergoing marrow transplantation. Risk, SIP, and BSI pre-transplant were found to be effective predictors of inpatient physical symptoms. Nausea, emesis and opioid use did not differ significantly between the treatment groups. The cognitive behavioral intervention, as applied in this study, was not effective in reducing the symptoms measured.
