Mindful positive emotion regulation as a treatment for addiction: from hedonic pleasure to self-transcendent meaning

My new theory paper was just published online in Current Opinion in Behavioral Sciences. This paper outlines my recent ideas about how an addictions treatment approach based on mindfulness can enhance healthy pleasure, joy, and meaning in life. Most addictions treatments are focused on decreasing negative psychological experiences (e.g., stress, craving) and unhealthy behaviors. Few have focused on increasing positive psychological experiences as a core treatment approach. This oversight ignores fundamental discoveries from addiction neuroscience that demonstrate the plasticity of the brain reward circuitry underlying addiction. Therapies that use mindfulness techniques to savor natural rewarding objects and events, self-generate internal reward responses, and access self-transcendence may remediate the dysfunction in the reward system and thereby reduce addictive behavior.

The abstract is below:

Chronic drug use is theorized to induce cortico-striatal neuroplasticity, driving an allostatic process marked by increased sensitivity to drug-related cues and decreased sensitivity to natural rewards that results in anhedonia and a dearth of positive affect. As such, positive emotion regulation represents a key mechanistic target for addictions treatment. This paper provides a conceptual model detailing how mindfulness may synergize a range of positive affective mechanisms to reduce addictive behavior, from savoring the hedonic pleasure derived from natural rewards, to self-generating interoceptive reward responses, and ultimately to cultivating self-transcendent meaning. These therapeutic processes may restructure reward processing from overvaluation of drug-related rewards back to valuation of natural rewards, and hypothetically, ‘reset’ the default mode network dysfunction that undergirds addiction.

Research on MORE and Mindfulness Covered in the News

Results from a new Stage 2 randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE), to be published later this summer in the Journal of Consulting and Clinical Psychology, have been covered in a news story that also details findings from a recently published study of the effects of mindfulness on deautomatization of habit behaviors. A second news story also did a really nice job describing results from this study.

Results from this study, conducted in 95 people with chronic pain who had been prescribed long-term opioid therapy, demonstrate that MORE significantly decreased chronic pain intensity and significantly decreased the risk of future opioid misuse. Further, MORE boosted a range of positive psychological functions, including positive emotions, savoring, meaning in life, and the sense of self-transcendence. Importantly, the MORE’s effects on reducing pain and opioid misuse were linked with these increases in positive psychological functioning, suggesting that teaching people to “savor the good” and increase the sense of joy, meaningfulness, and natural healthy pleasure in life may be an antidote to the current pain and opioid crises in America – modern epidemics that have been termed “diseases of despair.”

This is the second randomized controlled trial to demonstrate therapeutic effects of MORE on chronic pain symptoms and opioid misuse, providing compelling evidence of MORE’s efficacy as a means of alleviating the suffering caused by the opioid crisis.

First fMRI Pilot Study Published on the Effects of Mindfulness-Oriented Recovery Enhancement on Reward Processing in Addiction

IMORE-fMRI-SB‘m pleased to announce that the first fMRI brain imaging study of Mindfulness-Oriented Recovery Enhancement (MORE) has been published in the open-access journal Evidence-Based Complementary and Alternative Medicine (Froeliger et al., 2017). My colleague Brett Froeliger and I conducted this proof-of-concept pilot study at his TRAIN Lab at the Medical University of South Carolina to examine the effects of MORE on reward processes in the brains of people addicted to cigarettes. A sample of 13 smokers participated in a study testing MORE versus a comparison group. All participants underwent two fMRI scans 8 weeks apart. Between the first and second fMRI scan, participants in the MORE group learned mindfulness and reappraisal skills to decrease addictive reactions to cigarettes and savoring skills to increase responsiveness to natural rewards (e.g., social connection, natural beauty, healthy behaviors). Participants in the comparison group completed research measures but did not receive any treatment. Relative to the comparison group, MORE was associated with significant decreases in smoking (66% decrease) and significant increases in positive emotions. Crucially, MORE participants evidenced significant decreases in neural activity while viewing cigarette images in reward-related brain regions including the ventral striatum and ventromedial prefrontal cortex. MORE participants also demonstrated significant increases in neural activity in these same reward-related brain regions while they savored positive, natural-reward related images. Importantly, increases in brain activity during savoring were significantly correlated with smoking reduction and increased positive affect. These pilot findings provide preliminary evidence that MORE may facilitate the restructuring of reward processes and play a role in treating the pathophysiology of nicotine addiction. These findings converge with results from our other psychophysiological studies indicating that MORE may restructure reward processes in prescription opioid misuse (Garland, Froeliger, & Howard, 2014; Garland, Froeliger, & Howard, 2015; Garland, Howard, Zubieta, & Froeliger, 2017). Taken together, these data provide initial support for my restructuring reward hypothesis which asserts that mindfulness training may enhance a domain-general cognitive resource for restructuring reward learning from valuation of drug-related rewards to valuation of natural rewards and thereby reverse the downward spiral of addiction.

New R01 Grant from the National Institute on Drug Abuse: Targeting Chronic Pain and Prescription Opioid Misuse in Primary Care with Mindfulness-Oriented Recovery Enhancement

nidaRecently, I was awarded a R01 grant from the National Institute on Drug Abuse to conduct a full-scale clinical trial of Mindfulness-Oriented Recovery Enhancement (MORE) as an intervention to reduce chronic pain and prescription opioid misuse in primary care. This five-year study will compare the efficacy of MORE to supportive therapy for 260 chronic pain patients receiving long-term opioid therapy who are at risk for opioid misuse.

Opioids may be medically necessary for some individuals experiencing prolonged and intractable pain, and most patients take medicine as prescribed. Unfortunately, opioids rarely completely alleviate chronic pain, and when taken in high doses or for long periods of time, can lead to serious side effects, including death by overdose, as well as risk for opioid misuse, which affects about 1 in 4 opioid-treated patients. Misusing opioids by taking higher doses than prescribed or by taking opioids to self-medicate negative emotions can alter the brain’s capacity for hedonic regulation, making it difficult to cope with pain (e.g., causing hyperalgesia – an increased sensitivity of the nervous system to pain) and experience pleasure in life (e.g., reducing sensitivity of the brain to natural reward). As such, non-opioid pain treatments that target hedonic dysregulation may be especially helpful for reducing chronic pain and prevent opioid misuse.

Multiple studies suggest that MORE improves hedonic regulation in the brain, resulting in decreased pain and an increased ability to savor natural, healthy pleasure. People who participate in MORE show heightened brain and body responses to healthy pleasures, and report feeling more positive emotions by using of mindfulness as a tool to enhance savoring. These therapeutic effects of MORE on savoring may be critically important, because findings from several studies show that increasing sensitivity to natural reward through savoring may lead to decreased craving for drugs – a completely novel finding for the field of addiction science (Garland, 2016). Our NIDA-funded R01 will provide a rigorous test of whether MORE improves chronic pain and opioid misuse by targeting hedonic dysregulation.

In our NIDA-funded R01, patients are receiving MORE at community medical clinics throughout Salt Lake City. Providing MORE in the naturalistic setting where most chronic pain patients seek medical care will make the therapy accessible to the people who need it the most. Ultimately, my hope is that this project will advance a new form of integrative healthcare, in which doctors and nurses work alongside social workers and other behavioral health professionals to help patients reclaim a meaningful life from pain.

New Research Funding: Neuroimaging Research on the Effects of Mindfulness-Oriented Recovery Enhancement on Hedonic Regulation

mindfulness-centered-regulation-in-brainChronic pain is often treated with extended use of opioid analgesics, yet these drugs can alter the brain in ways that may make it difficult to cope with pain and may reduce the experience pleasure in life. Mindfulness-based interventions appear to be a promising means of addressing these issues, but research is needed to understand how such interventions change the brain to reduce suffering.

To that end, in September, 2016, I was recently awarded a five-year phased innovation grant from the National Institutes of Health’s (NIH) National Center for Complementary and Integrative Health entitled Effects of Mindfulness-Oriented Intervention on Endogenous Opioid Mechanisms of Hedonic Regulation in Chronic Pain (R61AT009296). The objective of the project is to study the effects of an innovative mindfulness-based intervention on brain mechanisms linked with pain and pleasure.

In the first two-year phase of the study ($800,000), I (Principal Investigator), along with my Co-Principal Investigator Jon-Kar Zubieta (Co-Principal Investigator), chair of the University of Utah’s Department of Psychiatry, will use positron emission tomography (PET) neuroimaging to assess the effects of Mindfulness-Oriented Recovery Enhancement (MORE) on restoring brain levels of endorphins in patients with chronic back pain who are being treated with prescription opioids.

This study represents the first use of PET in the history of science to quantify the effects of a mindfulness-based therapy on levels of endogenous opioids in the brain.

We will also use functional magnetic resonance imaging (fMRI) methods to assess how mindfulness training through MORE may increase people’s capacity to savor natural pleasure from positive and meaningful events in everyday life – a capacity that becomes diminished over time through the deleterious effects of chronic pain and prolonged opioid use on the brain. We will use a fMRI paradigm developed by my Co-Investigator Brett Froeliger, Assistant Professor of Neuroscience at the Medical University of South Carolina.

This study aims to test whether MORE might reverse this insensitivity to natural reward by targeting the endogenous opioid system and brain reward functions.

Following a successful first phase of the project, a three-year second phase ($2.2 million) will investigate whether patients with a particular genetic makeup that affects the expression of opioid receptors in the brain might benefit more from the mindfulness-based treatment. The second phase of the project will also assess the dose of mindfulness skill practice as a predictor of changes in endogenous opioid function and clinical correlates.

Based on the results of previous research, we hypothesize that mindfulness meditation training through MORE will restore proper function to the brain’s opioid receptors.  We will be able to measure how MORE changes the brain’s ability to regulate pain and respond to natural rewards, as well as deepen our understanding of exactly how these changes in neural mechanisms happen.

Overall, this project will unite expertise in mindfulness-based interventions with expertise in neurogenetics and the use of PET and fMRI to probe the neurobiological mechanisms of pain and emotional experience. By elucidating a key mechanism of meditation-based therapies, this program of translational research will further the emerging field of social work neuroscience and enable us to rapidly optimize MORE to increase the effectiveness of the intervention as it is rolled out in clinical practice.
