Mindfulness-based treatment to prevent addictive behavior relapse: theoretical models and hypothesized mechanisms of change

Being able to think when caught in the maelstrom - how adolescents used mindfulness when facing exams

PURPOSE

Research indicates that exam anxiety may decline with mindfulness-based interventions but there is a lack of research on adolescents' accounts of the processes involved. We explored high-school students' descriptions of how they perceived and applied mindfulness in managing anxiety-inducing thoughts related to academic performance following an 8-week Mindfulness-Based Stress Reduction (MBSR) course.

METHOD

Post-course individual semi-structured interviews with 22 high school students (2 males, mean age 17.8 years) were transcribed verbatim and analysed using reflexive thematic analysis.

RESULTS

The analyses identified six themes: (1) Noticing and attending to the attention-binding "maelstrom" of anxious thoughts and feelings (2) Attending to the breath to cope with the maelstrom, (3) "removing" and "getting rid of" anxious thoughts (4) Being able to "think" (5) awareness of more helpful thoughts, and (6) Agency and control. The findings are discussed in light of the Buddhist notion of "unwholesome thoughts" and the distinction between thought suppression and the use of breathing as a benign distraction. We propose that mindfulness encompasses both a receptive, nonjudgmental awareness and an active, intentional redirection of attention.

CONCLUSION

Mindfulness training aided participants by enhancing their capacity to disengage from fear-engaging thoughts, thereby maintaining them within their window of tolerance and facilitating cognitive processing.

Development and initial testing of mindful journey: a digital mindfulness-based intervention for promoting recovery from Substance use disorder

BACKGROUND/OBJECTIVES

There is a great unmet need for accessible adjunctive interventions to promote long-term recovery from substance use disorder (SUD). This study aimed to iteratively develop and test the initial feasibility and acceptability of Mindful Journey, a novel digital mindfulness-based intervention for promoting recovery among individuals with SUD.

PATIENTS/MATERIALS

Ten adults receiving outpatient treatment for SUD.

METHODS

Phase 1 (n = 5) involved developing and testing a single introductory digital lesson. Phase 2 included a separate sample (n = 5) and involved testing all 15 digital lessons (each 30- to 45-minutes) over a 6-week period, while also receiving weekly brief phone coaching for motivational/technical support.

RESULTS

Across both phases, quantitative ratings (rated on a 5-point scale) were all at or above a 4 (corresponding with 'agree') for key acceptability dimensions, such as usability, understandability, appeal of visual content, how engaging the content was, and helpfulness for recovery. Additionally, in both phases, qualitative feedback indicated that participants particularly appreciated the BOAT (Breath, Observe, Accept, Take a Moment) tool for breaking down mindfulness into steps. Qualitative feedback was used to iteratively refine the intervention. For example, based on feedback, we added a second core mindfulness tool, the SOAK (Stop, Observe, Appreciate, Keep Curious), and we added more example clients and group therapy videos. In Phase 2, 4 out of 5 participants completed all 15 lessons, providing initial evidence of feasibility. Participants reported that the phone coaching motivated them to use the app. The final version of Mindful Journey was a smartphone app with additional features, including brief on-the-go audio exercises and a library of mindfulness practices. Although, participants used these additional features infrequently.

CONCLUSIONS

Based on promising initial findings, future acceptability and feasibility testing in a larger sample is warranted. Future versions might include push notifications to facilitate engagement in the additional app features.

The methods and baseline characteristics of a multi-site randomized controlled trial evaluating mindfulness-based relapse prevention in conjunction with peer support to improve adherence to medications for opioid use disorders

Introduction

Medications for opioid use disorders (MOUD) remain the gold standard for treating OUD, but treatment initiation and adherence remain challenging. Exclusive utilization of pharmacotherapy as a treatment modality for OUD is sub-optimal, and a combination of psychotherapies and pharmacotherapies is recommended. General trends indicate the benefits of peer mentoring and MBRP separately. Therefore, we hypothesize that the combined effect of MBRP and Peer mentoring will produce synergistic improvements in MOUD adherence compared to an enhanced twelve-step facilitation (TSF).

Methods

This paper describes the methods and baseline characteristics of a multi-site randomized controlled trial evaluating the effectiveness of a combination of MBRP and peer support (MiMP) compared to an enhanced TSF in improving adherence to MOUD. Both MiMP and TSF are 12-week manualized protocols that utilize licensed therapists. The interventions are delivered in weekly group sessions that last about 75-90 minutes per session. The primary outcome is MOUD adherence. Secondary and exploratory outcomes include relapse, cravings, depression, anxiety, stress, quality of life, and pain catastrophizing.

Results

The participants' ages ranged from 21 years to 77 years, with a mean age of 44.5 (SD ± 11.5 years). There was an almost equal distribution of gender and place of residence. Overall, 51.9% (n=54) of participants identified as female and 48.1% (n=50) were male. Similarly, 51.9% (n=54) of participants resided in urban areas, while 48.1% (n=50) resided in rural areas. Participants identified as either black or white, with over three-quarters identifying as white (77.9%, n= 81) and 22.1% (n= 23) as black. Most participants randomized to the 12-step facilitation group were white (93.1%). Relationships and employment status were well distributed between categories. Over half of the participants reported some college or higher education. Over 90% of the participants made less than $75,000 per year. Some participants indicated that they had both public and private health insurance.

Discussion and conclusion

This study is innovative in several ways including combining MBRP and peer support, addressing comorbid mental health issues among individuals with OUD, utilizing manualized protocols, and evaluating of both physiological and self-reported measures in assessing cortisol reactivity as a predictor of relapse and treatment outcomes.

Effects of brief mindfulness training on smoking cue-reactivity in tobacco use disorder: Study protocol for a randomized controlled trial

BACKGROUND

The prevalence of Tobacco Use Disorder (TUD) represents a significant and pressing global public health concern, with far-reaching and deleterious consequences for individuals, communities, and healthcare systems. The craving caused by smoking cue is an important trigger for relapse, fundamentally hindering the cessation of cigarette smoking. Mindfulness interventions focusing on cue-reactivity was effective for the treatment of related dependence. Brief mindfulness training (BMT) meets the short-term needs for intervention but the effects still need to be examined. The objective of the present study is to investigate the impact of BMT intervention on smoking cue-reactivity among Chinese college students with TUD, to uncover the dynamic models of brain function involved in this process.

METHOD

A randomized control trial (RCT) based on electroencephalography (EEG) was designed. We aim to recruit 90 participants and randomly assign to the BMT and control group (CON) with 1:1 ratio. A brief mindfulness training will be administered to experimental group. After the intervention, data collection will be conducted in the follow-up stage with 5 timepoints of assessments. EEG data will be recorded during the smoking cue-reactivity task and 'STOP' brief mindfulness task. The primary outcomes include subjective reports of smoking craving, changes in EEG indicators, and mindfulness measures. The secondary outcomes will be daily smoking behaviours, affect and impulsivity, as well as indicators reflecting correlation between mindfulness and smoking cue-reactivity. To evaluate the impact of mindfulness training, a series of linear mixed-effects models will be employed. Specifically, within-group effects will be examined by analysing the longitudinal data. Additionally, the effect size for all statistical measurements will be reported, offering a comprehensive view of the observed effects.

DISCUSSION

The current study aims to assess the impact of brief mindfulness-based intervention on smoking cue-reactivity in TUD. It also expected to enhance our understanding of the underlying processes involved in brain function and explore potential EEG biomarkers at multiple time points.

Examining the validity of the addictions neuroclinical assessment domains in a crowdsourced sample of adults with current alcohol use

Several dimensional frameworks for characterizing heterogeneity in alcohol use disorder (AUD) have been proposed, including the Addictions Neuroclinical Assessment (ANA). The ANA is a framework for assessing individual variability within AUD across three domains corresponding to the proposed stages of the addiction cycle: reward (binge-intoxication stage), negative emotionality (withdrawal-negative affect stage), and cognitive control (preoccupation-anticipation stage). Recent work has evaluated the ANA's three-factor structure and construct validity, primarily in treatment-seekers with AUD. We extended this research by examining the factor structure, bias across alcohol use severity, longitudinal invariance, and concurrent and predictive validity of a novel assessment of the ANA domains in adults with past 12-month regular (10 + alcohol units/week) alcohol use. Participants recruited from Prolific (N = 732), a crowdsourced data collection platform, completed various self-report measures. A test-retest subsample (n = 234) completed these measures 30 days later. Split-half exploratory factor analysis and confirmatory factor analysis supported the three-factor structure of the ANA. The overall factor structure was invariant across 30 days. Concurrently and prospectively, ANA domains demonstrated convergent validity concerning theoretically aligned alcohol-related, psychological, and personality measures. However, there was evidence of poor discriminant validity, and several cognitive control and reward items demonstrated bias across alcohol use severity. Future research is needed to improve the measurement of ANA domains using multimodal indicators, examine longitudinal changes in domains and their relationship with alcohol use severity, characterize phenotypic subgroups based on relative levels of domains, and compare the utility of the ANA with other proposed frameworks for measuring AUD heterogeneity.

Development, feasibility, and acceptability of SPoRT: a dating violence and sexual risk prevention intervention for college student-athletes

BACKGROUND

Student-athletes are one subgroup of college students in the USA at risk for dating violence and sexual risk behaviors. Despite this, research on student-athletes' dating behaviors is limited; existing research pertains primarily to the National Collegiate Athletic Association (NCAA) Division I athletes and focuses on male student-athletes as perpetrators of dating and sexual violence. While some existing programs aim to reduce dating violence and promote healthy relationships, these programs are education based, and not tailored to the specific strengths and challenges of student-athletes. We therefore designed Supporting Prevention in Relationships for Teams (SPoRT), a novel, four-session prevention intervention for Division III student-athletes of all genders to reduce dating violence and sexual risk behavior by targeting knowledge and skills identified in pilot research, incorporating psychoeducation with techniques from cognitive-behavioral therapy, mindfulness, bystander intervention, and normative feedback.

METHODS

This study represents stage 1 of the National Institutes of Health (NIH) Stage Model for Behavioral Intervention Development, evaluating the feasibility and acceptability of SPoRT. We describe the development, content, and proposed delivery methods for SPoRT and evaluated the feasibility and acceptability of the program using a mixed-methods approach. Thirty college student-athletes (12 men, 18 women) completed questionnaires and participated in focus groups to provide feedback on the program's length, timing, group size and dynamics, content, and suggestions for making the SPoRT prevention intervention more feasible and acceptable.

RESULTS

Our recruitment procedures were successful, and participants rated the program as feasible in terms of delivery methods and logistics. Participants liked that SPoRT was developed based on pilot data collected from student-athletes, brief, and skills based and tailored to athletic team needs. SPoRT was perceived as appropriate and relevant to student-athlete needs in terms of dating violence and sexual risk prevention knowledge and skills. Most participants (63%) rated the program as "excellent" and said they would recommend it to others.

CONCLUSIONS

We found SPoRT to be both feasible and acceptable in terms of content and delivery. Suggested modifications will be incorporated into the SPoRT healthy relationships prevention intervention to be tested in an NIH Stage 1 efficacy trial.

Five Challenges in Implementing Cognitive Remediation for Patients with Substance Use Disorders in Clinical Settings

Many patients with substance use disorders (SUDs) present cognitive deficits, which are associated with clinical outcomes. Neuropsychological remediation might help rehabilitate cognitive functions in these populations, hence improving treatment effectiveness. Nardo and colleagues (Neuropsychology Review, 32, 161-191, 2022) reviewed 32 studies applying cognitive remediation for patients with SUDs. They underlined the heterogeneity and lack of quality of studies in this research field but concluded that cognitive remediation remains a promising tool for addictive disorders. We capitalize on the insights of this review to identify the key barriers that currently hinder the practical implementation of cognitive remediation in clinical settings. We outline five issues to be addressed, namely, (1) the integration of cognitive remediation in clinical practices; (2) the selection criteria and individual factors to consider; (3) the timing to be followed; (4) the priority across trained cognitive functions; and (5) the generalization of the improvements obtained. We finally propose that cognitive remediation should not be limited to classical cognitive functions but should also be extended toward substance-related biases and social cognition, two categories of processes that are also involved in the emergence and persistence of SUDs.

Efficacy of mindfulness-based relapse prevention in a sample of veterans in a substance use disorder aftercare program: A randomized controlled trial

BACKGROUND

Complementary integrative medicine, such as mindfulness-based interventions, (MBI) have demonstrated efficacy in the treatment of depression, anxiety, substance use disorders (SUDs), and pain. Mindfulness-based relapse prevention (MBRP) is an aftercare intervention targeting SUD relapse that integrates cognitive-behavioral relapse prevention and mindfulness meditation practices, raising awareness of substance use triggers and reactive behavioral patterns. This study evaluated the efficacy of MBRP in reducing relapse in veterans following completion of an SUD treatment program.

METHODS

This study was a two-site, randomized controlled trial comparing MBRP to 12-step facilitation (TSF) aftercare in military veterans following completion of intensive treatment for SUDs. The 8 weeks of 90-minute, group-based MBRP or TSF sessions were followed by 3-, 6- and 10-month follow-up periods with assessments of alcohol/substance use and secondary outcomes of depression, anxiety, and mindfulness.

RESULTS

Forty-seven percent of veterans attended ≥75 % of sessions. Veterans in both the MBRP and TSF aftercare groups maintained reductions in alcohol and illicit substance use during the aftercare treatment. Nineteen participants (11 %; 19/174) reported returning to alcohol use during the study treatment period and the study found no difference between study groups [MBRP: 9 % vs. TSF 13 %; p = 0.42]. Thirteen participants (7.5 %; 13/174) reported a return to illicit substance use during study treatment [MBRP: 5.4 % vs. TSF 10.3 % p = 0.34]. The number of days of drinking and illicit substance use was not different between groups (alcohol, p = 0.53; illicit substance use, p = 0.28).

CONCLUSION

Although retention in treatment limits interpretation of the findings, both MBRP and TSF were effective in maintenance of treatment gains following an intensive treatment program for veterans with SUDs. Future studies should focus on strategies to improve treatment participation.

Precision medicine in alcohol use disorder: Mapping etiologic and maintenance mechanisms to mechanisms of behavior change to improve patient outcomes

Precision medicine has been advanced as a potential solution to the problem of alcohol use disorder heterogeneity and modest alcohol use disorder treatment efficacy. The success of precision medicine lies in our ability to first identify the etiologic and maintenance mechanisms at play for a given person and then choose the treatment that is most likely to address such mechanisms. There exist several frameworks that describe empirically supported substance use disorder (SUD) etiologic and maintenance mechanisms (e.g., the Etiologic, Theory-based, Ontogenetic, Hierarchical [ETOH] Framework). There also exists a large literature on mechanisms of behavior change in alcohol use disorder treatment. However, the mechanism of behavior change literature on alcohol use disorder treatments has focused broadly on mechanisms of change rather than more specifically on core alcohol use disorder etiologic and maintenance mechanisms. Thus, the two types of mechanisms have never been integrated or systematically evaluated for their overlap. As such, the aim of the present brief review is to demonstrate how commonly used alcohol use disorder treatments may overlap with and directly target certain alcohol use disorder etiologic and maintenance mechanisms (specifically those described by the ETOH framework). We delineate empirically plausible overlapping mechanisms and theoretically plausible overlapping mechanisms that warrant more research. Last, based on the identification of empirically and theoretically plausible overlapping mechanisms, we elaborate on how ongoing work related to alcohol use disorder precision medicine may test specific hypotheses regarding which treatments work best for whom.

Associations of thalamocortical networks with reduced mindfulness in alcohol use disorder

Background

Increased mindfulness is associated with reduced alcohol consumption in patients with alcohol use disorder (AUD) after residential treatment. However, the underlying neurobiological mechanism of mindfulness in AUD is unclear. Therefore, we investigate the structural and functional alterations of the thalamocortical system with a focus on the mediodorsal thalamic nucleus (MD-TN), the default mode and the salience network (DMN/SN) which has previously been associated with mindfulness in healthy subjects. We hypothesized lower mindfulness and reduced structural and functional connectivity (FC) of the thalamocortical system, particularly in the DMN/SN in AUD. We assumed that identified neurobiological alterations in AUD are associated with impairments of mindfulness.

Methods

Forty-five abstinent patients with AUD during residential treatment and 20 healthy controls (HC) were recruited. Structural and resting-state functional MRI-scans were acquired. We analysed levels of mindfulness, thalamic volumes and network centrality degree of the MD-TN using multivariate statistics. Using seed-based whole brain analyses we investigated functional connectivity (FC) of the MD-TN. We performed exploratory correlational analyses of structural and functional DMN/SN measurements with levels of mindfulness.

Results

In AUD we found significantly lower levels of mindfulness, lower bilateral thalamic and left MD-TN volumes, reduced FC between MD-TN and anterior cingulum/insula and lower network centrality degree of the left MD-TN as compared to HC. In AUD, lower mindfulness was associated with various reductions of structural and functional aspects of the MD-TN.

Conclusion

Our results suggest that structural and functional alterations of a network including the MD-TN and the DMN/SN underlies disturbed mindfulness in AUD.

Use of a sequential multiple assignment randomized trial to test contingency management and an integrated behavioral economic and mindfulness intervention for buprenorphine-naloxone medication adherence for opioid use disorder

BACKGROUND

Buprenorphine-naloxone is a medication shown to improve outcomes for individuals seeking treatment for opioid use disorder (OUD); however, outcomes are limited by low medication adherence rates. This is especially true during the early stages of treatment.

METHODS

The present study proposes to utilize a sequential multiple assignment randomized trial design to compare two psychological interventions targeting buprenorphine-naloxone adherence: (1) contingency management (CM) and (2) brief motivational interviewing plus substance-free activities session plus mindfulness (BSM). Participants will be N = 280 adults who present to a university-based addictions clinic seeking treatment for OUD. Participants will be randomized to condition to receive 4 sessions of their assigned intervention (CM or BSM). Participants who are adherent, defined as attending physician appointments and having buprenorphine present in urine toxicology, will enter maintenance intervention for an additional 6 months. Those who are not adherent will be re-randomized to receive either the other intervention or both interventions. Follow-up will occur at 8 months post-randomization.

CONCLUSIONS

This novel design will examine the benefit of sequential treatment decisions following non-adherence. The primary outcome of this study is buprenorphine-naloxone medication adherence, as assessed by physician visit attendance and presence of buprenorphine in urine. Results will elicit the relative efficacy of CM and BSM compared to one another and whether keeping the initial treatment approach when adding the alternative approach for initially non-adherent individuals is beneficial.

The role of mindfulness, meditation, and peer support in recovery capital among Recovery Dharma members

INTRODUCTION

Recovery Dharma (RD) is a Buddhist-based peer support program for the treatment of addiction that incorporates mindfulness and meditation into meetings, program literature, and the recovery process, creating the opportunity to study these variables in a peer-support program context. Mindfulness and meditation are beneficial for people in recovery, yet we know little about their relationship to recovery capital, a positive indicator of recovery outcomes. We explored mindfulness and meditation (average length of sessions and average frequency per week) as predictors of recovery capital and examined perceived support in relation to recovery capital.

METHODS

The study recruited participants (N = 209) through the RD website, newsletter and social media pages for an online survey that included measures of recovery capital, mindfulness, perceived support, and questions about meditation practices (e.g., frequency, duration). Participants' mean age was 46.68 years (SD = 12.21), with 45 % female (5.7 % non-binary), and 26.8 % from the LGBTQ2S+ community. The mean time in recovery was 7.45 years (SD = 10.37). The study fitted univariate and multivariate linear regression models to determine significant predictors of recovery capital.

RESULTS

As anticipated, multivariate linear regressions indicated that mindfulness (β = 0.31, p < .001), meditation frequency (β = 0.26, p < .001), and perceived support from RD (β = 0.50, p < .001) were all significant predictors of recovery capital when controlling for age and spirituality. However, longer time in recovery and the average duration of meditation sessions did not predict recovery capital as anticipated.

CONCLUSIONS

Results indicate the importance of a regular meditation practice for recovery capital rather than engaging in prolonged sessions infrequently. The results also support previous findings, which point to the influence of mindfulness and meditation on positive outcomes for people in recovery. Further, peer support is associated with higher recovery capital in RD members. This study is the first examination of the relationship between mindfulness, meditation, peer support, and recovery capital in recovering people. The findings lay the groundwork for the continued exploration of these variables as they relate to positive outcomes both within the RD program and in other recovery pathways.

Neural Correlates of Cue Reactivity and the Regulation of Craving in Substance Use Disorders

Abstract. Theoretical background: Considerable progress has been made in illuminating the neural basis of the compulsive use patterns characterizing substance use disorders. It has been suggested to utilize these findings to alleviate the health burden associated with substance use. Objective: We address how neuroimaging research can provide these benefits. Methods: Based on neurobiological models of addiction, we highlight neuroimaging research elucidating neural predictors of relapse and how treatments modify these markers. Results: With the focus on cue reactivity, brain activity related to the motivational salience of drugs and automatized use behaviors can predict relapse. Cue reactivity changes with abstinence, and it remains to be determined whether such changes confer periods of critical relapse susceptibility. Conclusions: Several established and emerging interventions modulate brain activity associated with drug value. However, executive deficits in addiction may compromise interventions targeting control-related prefrontal brain areas. Lastly, it remains more difficult to change the brain responses mediating habitual behaviors.

Mindfulness to Manage Moral Injury: Rationale and development of a live online 7-week group intervention for veterans with moral injury

Background

Military service puts service members at risk for moral injury. Moral injury is an array of symptoms (e.g., guilt, shame, anger) that develop from events that violate or transgress one's moral code.

Objective

We describe adaption of in-person mindfulness training program, Mindfulness to Manage Chronic Pain (MMCP), to address symptoms of moral injury to be delivered live via the web. We discuss how we will assess benchmarks (i.e., recruitment, credibility and acceptability, completion rates, and adherence) of the Mindfulness to Manage Moral Injury (MMMI) program.

Methods

Aim 1: To develop and then adapt the MMCP program based on feedback from experts and veterans who took part in Study 1. Aim 2: To develop an equally intensive facilitator-led online Educational Support (ES) program to serve as a comparison intervention and conduct a run-through of each program with 20 veterans (10 MMMI; 10 ES). Aim 3: To conduct a small-scale randomized controlled trial (N = 42 veterans; 21 MMMI; 21 ES) in which we will collect pre-post-test and weekly benchmark data for both refined intervention arms.

Results

Study 1 and 2 are completed. Data collection for Study 3 will be completed in 2022.

Conclusion

MMMI is designed to provide a live facilitated mindfulness program to address symptoms of moral injury. If Study 3 demonstrates good benchmarks, with additional large-scale testing, MMMI may be a promising treatment that can reach veterans who may not seek traditional VAMC care and/or who prefer a web-based program.

Mindfulness-Based Smoking Cessation Delivered Through Telehealth and Text Messaging for Low-Income Smokers: Protocol for a Randomized Controlled Trial

BACKGROUND

Tobacco use is the leading cause of preventable morbidity and mortality. Adults with low income and members of certain racial and ethnic minority groups are less likely to quit, and therefore, they experience profound tobacco-related health disparities. Mindfulness training can increase the rates of smoking cessation and lapse recovery, and telehealth and SMS text messaging have the potential to provide more accessible treatment.

OBJECTIVE

This study aims to test the efficacy of delivering mindfulness-based smoking cessation treatment through text messaging (iQuit Mindfully) and telehealth (group videoconferencing), both as stand-alone interventions and in combination. In addition, it aims to examine the underlying mechanisms of mindfulness treatment.

METHODS

In this 2×2 randomized controlled trial, participants are randomized into 1 of 4 groups based on assignment to iQuit Mindfully text messages (yes or no) and mindfulness videoconference groups (yes or no). The primary outcomes are biochemically verified smoking abstinence at 8, 12, and 24 weeks after the start of treatment. Secondary outcomes include the frequency of home mindfulness practice and self-reported levels of mindfulness, emotions, craving, withdrawal, dependence, self-efficacy, and social support.

RESULTS

Recruitment, treatment, and assessment began in spring and summer 2021, and data collection is expected to continue through spring 2024.

CONCLUSIONS

This project aims to improve smoking cessation outcomes for low-income, racially and ethnically diverse smokers through mindfulness-based telehealth group counseling and text messaging support. We also aim to advance the scientific study of the mechanisms of action of mindfulness treatment, which could inform the development of more efficacious and efficient treatments to reduce tobacco disparities.

Comparative effectiveness of mindfulness and mindful eating programmes among low-income overweight women in primary health care: A randomised controlled pragmatic study with psychological, biochemical, and anthropometric outcomes

Obesity is a chronic and multifactorial disease, with growing rates in the last 50 years worldwide, reaching pandemic levels. It is a major public health problem and is difficult to treat. Different approaches have been used to improve this scenario, including mindfulness-based interventions to enhance dietary behaviour and nutritional status. We compared the effectiveness of a 10-week mindful eating programme with that of a 10-week mindfulness programme and of a no-treatment control group. The sample was composed of adult, low-income women with a body mass index (BMI) ≥ 25 to < 40 receiving primary health care in São Paulo, Brazil. The participants (n = 284) were randomised into 3 groups: the control, mindfulness, and mindful eating. We took anthropometric and body composition measurements, applied psychometric measures, and performed biochemical tests at pre-intervention, post-intervention, and after 3 months. We estimated the regression coefficients among the analysis of adherent participants (per protocol: PP) and among those of all participants randomised to treatment (intention-to-treat: ITT) in addition to multiple imputation (MI). Both groups showed improvement in eating behaviour and reduction of binge eating both in the post-intervention and follow-up periods, but without significant changes in weight or most of the biological tests. Those in the mindful eating programme performed slightly better than those in the mindfulness and control groups in terms of improving eating behaviour and reducing binge eating among low-income overweight women.

Acting with awareness moderates the association between lifetime exposure to interpersonal traumatic events and craving via trauma symptoms: a moderated indirect effects model

BACKGROUND

History of exposure to traumatic events (ETE) is common among women in substance use disorder (SUD) treatment and is related to craving. We examined whether ETE (i.e., emotional, physical, sexual abuse) in childhood, adulthood, or both is related to craving via trauma symptoms and how trait mindfulness might attenuate this association.

METHODS

Baseline data from a larger randomized clinical trial of a mindfulness-based intervention for women (N = 245) in SUD treatment were used. Inclusion criteria were: 18-65 years of age, SUD diagnosis, English fluency, no cognitive impairment, and willingness to be audio recorded and provide consent. Demographics and validated measures of ETE, posttraumatic stress symptoms, trait mindfulness, and substance use craving were collected via in-person interviews. Descriptive statistics, correlational analysis, and relative direct, indirect, and conditional indirect effects models were run.

RESULTS

Most participants identified as Hispanic (58.5%), had at least a high school education (52.2%), with a mean age of 32.2. Women reported ETE in childhood only (20.4%), adulthood only (17.5%), both childhood and adulthood (50.0%), and never (11.4%). Compared to women with ETE in both childhood and adulthood, those with exposure in adulthood only (β = -.10, 95% CI = -.20, -.02) or no exposure (β = -.11, 95% CI = -.23, -.03; [∆R2= .347, F(8, 245) = 15.7, p < .001) had lower craving via lower trauma symptomatology but no difference when compared to those with ETE only in childhood. Acting with awareness moderated this indirect effect (∆R2 = .04, F(3, 245) = 4.66, p = .004. At low levels of awareness, women with ETE during both childhood and adulthood reported higher craving via trauma symptomatology than women with no exposure or only adulthood exposure.

CONCLUSIONS

Low levels of acting with awareness may worsen trauma symptoms after ETE, which in turn may lead to more craving for women in substance use treatment. Despite a small moderating effect size, acting with awareness may have clinical significance due to the prevalence of trauma symptoms among women in SUD treatment.

Teacher's Corner: An R Shiny App for Sensitivity Analysis for Latent Growth Curve Mediation

Mechanisms of behavior change are the processes through which interventions are hypothesized to cause changes in outcomes. Latent growth curve mediation models (LGCMM) are recommended for investigating the mechanisms of behavior change because LGCMM models establish temporal precedence of change from the mediator to the outcome variable. The Correlated Augmented Mediation Sensitivity Analyses (CAMSA) App implements sensitivity analysis for LGCMM models to evaluate if a mediating path (mechanism) is robust to potential confounding variables. The CAMSA approach is described and applied to simulated data, and data from a research study exploring a mechanism of change in the treatment of substance use disorder.

Mechanisms of Behavior Change in Substance Use Disorder With and Without Formal Treatment

This article provides a narrative review of studies that examined mechanisms of behavior change in substance use disorder. Several mechanisms have some support, including self-efficacy, craving, protective behavioral strategies, and increasing substance-free rewards, whereas others have minimal support (e.g., motivation, identity). The review provides recommendations for expanding the research agenda for studying mechanisms of change, including designs to manipulate putative change mechanisms, measurement approaches that expand the temporal units of analysis during change efforts, more studies of change outside of treatment, and analytic approaches that move beyond mediation tests. The dominant causal inference approach that focuses on treatment and individuals as change agents could be expanded to include a molar behavioral approach that focuses on patterns of behavior in temporally extended environmental contexts. Molar behavioral approaches may advance understanding of how recovery from substance use disorder is influenced by broader contextual features, community-level variables, and social determinants of health. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Cognitive behavioural group therapy with mindfulness for kleptomania: an open trial

Kleptomania is an addiction to stealing without an economic motive; therefore, an examination of effective interventions as a preventive measure is needed. The effectiveness of cognitive behavioural therapy (CBT) combined with mindfulness for the treatment of addiction has been previously indicated, and it is presumed to be effective for kleptomania; however, this relationship remains unstudied. Therefore, this study aimed to examine the effectiveness of cognitive behavioural group therapy (CBGT) combined with mindfulness for treating kleptomania. The results of a 12-session programme of CBGT combined with mindfulness for 22 patients with kleptomania showed that kleptomania symptoms and quality of life (QOL) improved. Furthermore, the recovery process revealed that the improvement of distress tolerance affected the improvement of kleptomania symptoms and that the improvement of reward perception and distress tolerance affected the improvement of stress response and QOL. These results suggest that CBGT combined with mindfulness may be effective in improving symptoms and QOL in kleptomania.

Association Between the Patterns of Five Unhealthy Behaviors and Suicidal Behaviors Among Adolescents in Six Provinces of China

BACKGROUND

In adolescents, multiple unhealthy behaviors frequently occur together and are likely to be associated with suicidal behaviors (SBs), increasing the risk of suicide. This study aimed to clarify the potential patterns of unhealthy behaviors in Chinese adolescents and to examine the associations between the different patterns of unhealthy behaviors and SBs.

METHODS

A total of 22,628 middle school students were enrolled in this study. Self-reported unhealthy behaviors and SBs were investigated using questionnaires. Latent class analysis (LCA) was performed based on five unhealthy behaviors [smoking, alcohol use (AU), diet pill use (DPU), screen time (ST), and problematic mobile phone use (PMPU)]. Multivariate logistic regressions were used to examine associations between the different patterns of unhealthy behaviors and SBs.

RESULTS

Four subgroups of unhealthy behaviors were identified by LCA, including high-risk class (smoking/AU/DPU/PMPU/ST), moderate-risk class 1 (DPU/PMPU), moderate-risk class 2 (smoking/AU/ST), and low-risk class. Compared with the low-risk class, moderate-risk class 1, moderate-risk class 2, and high-risk class had higher risks of suicidal ideation, suicide plan, and suicide attempt.

CONCLUSIONS

These findings suggested that patterns of unhealthy behaviors were related to SBs in Chinese adolescents. Accordingly, considerations of different classes of unhealthy behaviors may be essential for developing effective preventive programs.

Effective psychological therapies to improve lifestyle behaviors in (pre)pregnant women: A systematic review

Poor lifestyle behaviors impact (pre)pregnant women by affecting pregnancy outcomes and offspring health. This systematic review provides an overview of psychological therapies to support lifestyle behavior changes among (pre)pregnant women.

Scientific databases were searched from their inception to 20 December 2020 for studies investigating the effects of psychological therapies on improvements in lifestyle behaviors.

Studies were eligible if they included (pre)pregnant women, examined the effects of a psychological therapy on at least one lifestyle behavior and used a control group receiving usual pregnancy care or a non-psychological intervention. Lifestyle behaviors of interest were dietary intake, physical activity, smoking, alcohol consumption, drug use, body weight loss and body weight gain during pregnancy. Pregnancy complications were included as outcome measures.

Motivational interviewing (MI) (n = 21), cognitive behavioral therapy (CBT) (n = 8), incentive-based contingency management (IBCM) (n = 9), mindfulness (n = 1) and hypnosis (n = 1) were investigated as lifestyle behavior interventions. The findings revealed that MI was effective in reducing (self-reported) smoking and alcohol consumption and restricting gestational weight gain (GWG). CBT was only studied as an intervention to restrict GWG and the results predominantly confirmed its effectiveness. IBCM showed the strongest effect on reducing smoking and substance use. The studies using hypnosis or mindfulness to reduce smoking or restrict GWG, respectively, showed no associations.

The use of psychological therapies to improve lifestyle behaviors among (pre)pregnant women is new and the scientific proof is promising. Before wide implementation is legitimated, more evidence is needed on the consequences of lifestyle change for pregnancy outcomes.

The Choice Point Model of Acceptance and Commitment Therapy With Inpatient Substance Use and Co-occurring Populations: A Pilot Study

Objectives: Acceptance and Commitment Therapy (ACT) is an empirically supported treatment which aims to enhance self-acceptance and a commitment to core values. The present study examined the effectiveness of the Choice Point model of ACT in a residential substance use disorder (SUD) setting. Choice Point is a contemporary approach to ACT and targets transdiagnostic processes.

Methods: This uncontrolled quasi-experimental design assessed 47 participants taking part in Choice Point for Substances (CHOPS) in order to investigate its influence on psychological inflexibility, values-based action, and self-compassion over time. The study additionally assessed for sleeper effects and associations between transdiagnostic processes and warning signs of relapse.

Results: Findings demonstrated a decrease in psychological inflexibility and increases in values-based action and self-compassion over time. Gains were maintained at follow-up, and sleeper effects were observed for psychological inflexibility and mindfulness. Correlational analysis suggested that all transdiagnostic processes were related to warning signs of relapse at follow-up.

Conclusion: These results provide preliminary evidence for the feasibility, acceptability, and effectiveness of CHOPS for SUD. Observed sleeper effects in psychological inflexibility and mindfulness indicate that CHOPS may provide longer-term benefits critical to a population where relapse is common. While encouraging, these findings should be interpreted with caution. Future research should utilize comparison groups when investigating CHOPS.

Mindfulness-based interventions for substance use disorders

BACKGROUND

Substance use disorders (SUDs) are highly prevalent and associated with a substantial public health burden. Although evidence-based interventions exist for treating SUDs, many individuals remain symptomatic despite treatment, and relapse is common.Mindfulness-based interventions (MBIs) have been examined for the treatment of SUDs, but available evidence is mixed.

OBJECTIVES

To determine the effects of MBIs for SUDs in terms of substance use outcomes, craving and adverse events compared to standard care, further psychotherapeutic, psychosocial or pharmacological interventions, or instructions, waiting list and no treatment.

SEARCH METHODS

We searched the following databases up to April 2021: Cochrane Drugs and Alcohol Specialised Register, CENTRAL, PubMed, Embase, Web of Science, CINAHL and PsycINFO. We searched two trial registries and checked the reference lists of included studies for relevant randomized controlled trials (RCTs).

SELECTION CRITERIA

RCTs testing a MBI versus no treatment or another treatment in individuals with SUDs. SUDs included alcohol and/or drug use disorders but excluded tobacco use disorders. MBIs were defined as interventions including training in mindfulness meditation with repeated meditation practice. Studies in which SUDs were formally diagnosed as well as those merely demonstrating elevated SUD risk were eligible.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

Forty RCTs met our inclusion criteria, with 35 RCTs involving 2825 participants eligible for meta-analysis. All studies were at high risk of performance bias and most were at high risk of detection bias. Mindfulness-based interventions (MBIs) versus no treatment Twenty-four RCTs included a comparison between MBI and no treatment. The evidence was uncertain about the effects of MBIs relative to no treatment on all primary outcomes: continuous abstinence rate (post: risk ratio (RR) = 0.96, 95% CI 0.44 to 2.14, 1 RCT, 112 participants; follow-up: RR = 1.04, 95% CI 0.54 to 2.01, 1 RCT, 112 participants); percentage of days with substance use (post-treatment: standardized mean difference (SMD) = 0.05, 95% CI -0.37 to 0.47, 4 RCTs, 248 participants; follow-up: SMD = 0.21, 95% CI -0.12 to 0.54, 3 RCTs, 167 participants); and consumed amount (post-treatment: SMD = 0.10, 95% CI -0.31 to 0.52, 3 RCTs, 221 participants; follow-up: SMD = 0.33, 95% CI 0.00 to 0.66, 2 RCTs, 142 participants). Evidence was uncertain for craving intensity and serious adverse events. Analysis of treatment acceptability indicated MBIs result in little to no increase in study attrition relative to no treatment (RR = 1.04, 95% CI 0.77 to 1.40, 21 RCTs, 1087 participants). Certainty of evidence for all other outcomes was very low due to imprecision, risk of bias, and/or inconsistency. Data were unavailable to evaluate adverse events. Mindfulness-based interventions (MBIs) versus other treatments (standard of care, cognitive behavioral therapy, psychoeducation, support group, physical exercise, medication) Nineteen RCTs included a comparison between MBI and another treatment. The evidence was very uncertain about the effects of MBIs relative to other treatments on continuous abstinence rate at post-treatment (RR = 0.80, 95% CI 0.45 to 1.44, 1 RCT, 286 participants) and follow-up (RR = 0.57, 95% CI 0.28 to 1.16, 1 RCT, 286 participants), and on consumed amount at post-treatment (SMD = -0.42, 95% CI -1.23 to 0.39, 1 RCT, 25 participants) due to imprecision and risk of bias. The evidence suggests that MBIs reduce percentage of days with substance use slightly relative to other treatments at post-treatment (SMD = -0.21, 95% CI -0.45 to 0.03, 5 RCTs, 523 participants) and follow-up (SMD = -0.39, 95% CI -0.96 to 0.17, 3 RCTs, 409 participants). The evidence was very uncertain about the effects of MBIs relative to other treatments on craving intensity due to imprecision and inconsistency. Analysis of treatment acceptability indicated MBIs result in little to no increase in attrition relative to other treatments (RR = 1.06, 95% CI 0.89 to 1.26, 14 RCTs, 1531 participants). Data were unavailable to evaluate adverse events.

AUTHORS' CONCLUSIONS

In comparison with no treatment, the evidence is uncertain regarding the impact of MBIs on SUD-related outcomes. MBIs result in little to no higher attrition than no treatment. In comparison with other treatments, MBIs may slightly reduce days with substance use at post-treatment and follow-up (4 to 10 months). The evidence is uncertain regarding the impact of MBIs relative to other treatments on abstinence, consumed substance amount, or craving. MBIs result in little to no higher attrition than other treatments. Few studies reported adverse events.

The Role of Pretreatment Expectancy on Substance Use Outcomes in Women Mandated to Mindfulness-Based Relapse Prevention

Background: More than one-third of justice-involved individuals meet the criteria for substance use disorder (SUD). Many studies show that treatment expectancy predicts longitudinal SUD outcomes; however, results are inconsistent, and the role of treatment expectancy on SUD outcomes for individuals mandated to a mindfulness-based intervention (MBI) is unknown. Mindfulness-based relapse prevention (MBRP) has shown efficacy with justice-involved populations; however, enrollment in MBRP is typically voluntary. The current study assessed whether pretreatment expectancy predicted SUD- and affect-related outcomes in a sample of women (n = 54) mandated to MBRP as part of their residential SUD programming. Method: The authors employed a quasiexperimental design and administered measures at pre-, mid-, and postcourse. Results: Following mandatory participation in MBRP, significant reductions in craving and substance use were observed. However, contrary to hypotheses, higher pretreatment expectancy predicted greater substance dependence at postcourse. Conclusions: Positive treatment expectancy within the context of an MBI was not related to favorable posttreatment outcomes; in fact, it was related to higher postcourse substance dependence. This suggests that MBIs may be suitable for mandated individuals who may not have voluntarily chosen to participate in such an intervention, and thus may have lower expectancy for the treatment. This finding needs to be replicated in a larger sample to warrant a firmer conclusion.

An exploration of thriving over time in recovery

INTRODUCTION

Emerging models of recovery have redirected the traditional focus on relapse prevention to an emphasis on wellness. According to this new framework of recovery, aspects of thriving can strengthen recovery and prevent relapse in substance use. However, the empirical support for these models is sparse. To fill the gap in the literature, the authors sought to predict the risk of relapse based on factors of thriving.

METHOD

Participants consisted of a stratified sample of 412 adults in early, middle, and late stages of recovery (based on length of time in recovery) who the study recruited via Qualtrics Online Panels. We utilized a sequential regression to examine the ability of factors of thriving, the influence of time in recovery and demographic variables to predict relapse risk.

RESULTS

Thriving, length of recovery, and demographics significantly predicted risk of relapse (p < .001, R² = 65%), with Thriving accounting for 55% of the variance (ΔR² = 55%).

CONCLUSION

These findings demonstrate that the natural developmental process that comes from the passage of time dedicated to recovery is significant but thriving or the quality of that time serves as a stronger protective factor preventing relapse. Addiction treatment and prevention specialists could benefit from including thriving in conceptual models and interventions for recovery. Further, these findings provide support for holistic models of addiction recovery.

Mindfulness-based relapse prevention for cannabis regular users: Preliminary outcomes of a randomized clinical trial

Mindfulness-based approaches have shown their effectiveness in caring for patients with substance use disorders (SUD). Mindfulness-based relapse prevention (MBRP) integrates practices from mindfulness-based interventions and cognitive-behavioral relapse prevention (RP) approaches. This article presents the preliminary results of a study that measures the effectiveness of an MBRP protocol for volunteer cannabis users willing to reduce or stop their consumptions. Twenty cannabis users were randomly assigned to either receive an eight-week outpatient MBRP program or treatment as usual (TAU). Cannabis use was assessed weekly through the timeline follow back (TLFB). Eighty percent of individuals received MBRP treatment and 60% of individuals received TAU completed treatment. Preliminary results did not find significant difference at the end of treatment (week 8) regarding the number of joints smoked. Despite the absence of any significant difference between the two groups, the contribution of mindfulness in the caring of SUD seems encouraging and promising. Many MBRP group participants reported qualitative changes in the way they consumed. This study will be continued in order to evaluate the effectiveness of MBRP on a larger number of subjects.

Efficacy of mindfulness-based relapse prevention in veterans with substance use disorders: Design and methodology of a randomized clinical trial

Mindfulness based interventions have been shown to be efficacious in treating depression, anxiety, pain and substance use disorders (SUDs). Mindfulness-Based Relapse Prevention (MBRP) is an intervention that integrates cognitive-behavioral relapse prevention and mindfulness meditation practices, in an 8-week, manualized group intervention designed to treat SUDs by helping patients regulate negative emotional states and reactive behavior. This paper describes the rationale, study design and methodology of a two-site, randomized controlled trial comparing MBRP to 12-Step Facilitation (TSF) in military Veterans following completion of intensive outpatient treatment for SUDs. The 8 weeks of 90-min, group-based MBRP or TSF sessions are followed by 3-, 6- and 10-month follow-up period with assessments of alcohol/drug use, quality of life, depression, anxiety, mindfulness and other functional outcomes, such as employment. The primary hypothesis is that MBRP will be significantly better than TSF in promoting recovery and prevention of relapse to substance use in a military Veteran population. The secondary hypothesis is that MBRP will lead to greater improvements in quality of life, depression/anxiety, and functional outcomes, such as employment. This study is designed to provide information about the use of group-based MBRP as a relapse prevention strategy for military Veterans who have completed an intensive SUD clinical treatment program. Clinical Trial Identifier: NCT02326363.

Craving management: Exploring factors that influence momentary craving-related risk of cannabis use among young adults

Young adult frequent cannabis use has increased in prevalence and some frequent users have problems reducing their use. A strong link between momentary craving and subsequent use behaviors among individuals with problematic cannabis use has been reported in the literature, including young adults. In treatment contexts, interventions based on associative learning and reinforcement aim to reduce the prevalence of problematic substance use by altering the association between craving and use by increasing craving management skills such as mindfulness and reducing unhelpful responding such as avoidance or suppression. However, this model has not been tested among young adult cannabis users. The current study examined the influence of trait and state craving management strategies (mindfulness, coping style, experiential avoidance, and craving beliefs) on the link between momentary craving and use, using ecological momentary assessment in a sample of young adults with problematic use interested in reducing their use. Results demonstrated that two craving management constructs were associated with use: non-reactivity (p = 0.02) and non-judgment (p < 0.01). Interactions with momentary craving were observed for two constructs: non-judgmentalness (p = 0.02) and craving beliefs (p < 0.01). Findings suggest that treatments that increase non-reactivity and non-judgmentalness may reduce the occurrence of cannabis use for young adults contemplating reduction during an important period of biopsychosocial development by mitigating the impact of craving or directly reducing use. Additionally, negative beliefs about craving may serve a protective function during acute periods of elevation in momentary craving, an unexpected finding deserving further investigation.

Minding the Gap: Leveraging Mindfulness to Inform Cue Exposure Treatment for Substance Use Disorders

Despite extinction-based processes demonstrating efficacy in the animal extinction and human anxiety literatures, extinction for substance use disorders (SUD) has shown poor efficacy (i. e., cue exposure treatment [CET]). Reasons for this lack of success include common threats to extinction, such as renewal and reinstatement. In recent decades, research on mindfulness for SUD has flourished, and a key aspect of these mindfulness-based interventions includes teaching individuals to stay present with whatever experience they have, even if unpleasant, without trying to change/escape/avoid it. Similarly, CET teaches individuals to not escape/avoid conditioned responses (e.g., craving) by engaging in drug use behavior. This paper discusses how mindfulness-based research and practices could positively influence CET through future research (e.g., Could mindfulness practice attenuate renewal? Might mindfulness training + CET enhance the ability to extinguish the most salient or motivational cues?), with the long-term goal of improving SUD treatment.

A dismantling study on imaginal retraining in smokers

Imaginal retraining is a noncomputerized variant of cognitive bias modification, an intervention aimed at reducing craving in substance use disorders and behavioral addictions. We conducted a dismantling study to elucidate which of its multiple components are effective and hence essential ingredients of the training and which are ineffective (and hence perhaps dispensable) in reducing craving. We randomized 187 smokers to one out of six conditions that instructed participants to perform a brief intervention. In four of these, participants were instructed to perform isolated components of the imaginal retraining protocol, and in the two other conditions participants either suppressed or simply observed (control condition) the image of a cigarette. Before and after the intervention, participants were asked to rate their level of craving and how pleasant they found three smoking-related images. We examined within-group changes by means of paired t-tests separately across conditions (trial registration: DRKS00021044). Mental distancing from cigarettes (without a corresponding actual physical movement; non-motor retraining) led to a significant decline in craving (paired t-test), which remained significant when compared to the control condition. The effects of other components of the retraining were less consistent. The present study shows that a single therapeutic "dose" of distinct components involved in imaginal retraining can reduce craving for cigarettes. Future trials should investigate the effectiveness of components of imaginal retraining not yet tested (e.g., mood induction) and whether combinations and repetition of single components strengthen or dilute efficacy.

The Pornography "Rebooting" Experience: A Qualitative Analysis of Abstinence Journals on an Online Pornography Abstinence Forum

A growing number of individuals using online forums are attempting to abstain from pornography (colloquially termed "rebooting") due to self-perceived pornography-related problems. The present qualitative study explored phenomenological experiences of abstinence among members of an online "rebooting" forum. A total of 104 abstinence journals by male forum members were systematically analyzed using thematic analysis. A total of four themes (with a total of nine subthemes) emerged from the data: (1) abstinence is the solution to pornography-related problems, (2) sometimes abstinence seems impossible, (3) abstinence is achievable with the right resources, and (4) abstinence is rewarding if persisted with. Members' primary reasons for initiating "rebooting" involved desiring to overcome a perceived addiction to pornography and/or alleviate perceived negative consequences attributed to pornography use, especially sexual difficulties. Successfully achieving and maintaining abstinence was typically experienced to be very challenging due to habitual behavior patterns and/or cravings triggered by a multiplicity of cues for pornography use, but a combination of internal (e.g., cognitive-behavioral strategies) and external (e.g., social support) resources made abstinence attainable for many members. A range of benefits attributed to abstinence by members suggest that abstaining from pornography could potentially be a beneficial intervention for problematic pornography use, although future prospective studies are needed to rule out possible third variable explanations for these perceived effects and to rigorously evaluate abstinence as an intervention. The present findings shed light on what the "rebooting" experience is like from members' own perspectives and provide insights into abstinence as an approach for addressing problematic pornography use.

Development of a mindfulness-based treatment for smoking cessation and the modification of alcohol use: A protocol for a randomized controlled trial and pilot study findings

The combined use of cigarettes and alcohol is associated with an increased risk of morbidity and mortality. Yet, efficacious interventions that address both behaviors concurrently are lacking. Smoking cessation and alcohol modification not only garner health benefits, but there is also value in addressing alcohol use in the context of smoking cessation to reduce the risk for smoking relapse. In this paper we describe the development of mindfulness-based relapse prevention for smoking cessation and alcohol modification (MBRP-SA) and pilot study findings (Phase 1). Next, details regarding the methods and design of an ongoing, randomized controlled trial, Project RISE (Phase 2), are described. MBRP-SA is a group-based intervention that consists of eight weekly treatment sessions. Results from the Phase 1 pilot study (N = 21 enrolled) indicated that participants planned to use the skills learned in their everyday activities and to address their smoking and alcohol goals. Based on the progression of Phase 1 cohorts, modifications were made to the inclusion/exclusion criteria and recruitment methods that will be implemented in Phase 2. Phase 2 will assess the feasibility and acceptability of MBRP-SA, delivered via live online groups, as a primary treatment option for smoking cessation and alcohol use modification.

Mindfulness-Based Intervention Effects on Substance Use and Relapse Among Women in Residential Treatment: A Randomized Controlled Trial With 8.5-Month Follow-Up Period From the Moment-by-Moment in Women's Recovery Project

OBJECTIVE

We tested the efficacy of Moment-by-Moment in Women's Recovery (MMWR), a mindfulness training program adapted for ethnoculturally diverse women with complex social and clinical histories in residential treatment for substance use disorder, on substance use and relapse outcomes.

METHODS

Participants were randomized to MMWR (n = 100; 60% Hispanic/Latina, 18% non-Hispanic Black) or the attention control condition, Neurobiology of Addiction (n = 100; 56% Hispanic/Latina, 21% non-Hispanic Black). Substance use outcomes (days until first use, days of use, and relapse status: abstained, lapsed, relapsed) were obtained from interviewer-assisted timeline followback for an 8.5-month follow-up period spanning the intervention start through the 6-week intervention period and 7 months after the intervention ended.

RESULTS

An intent-to-treat survival analyses showed that time delay to first marijuana use favored MMWR (hazard ratio = 0.44, 95% confidence interval = 0.20-0.98, p = .049) with a medium-to-large effect size. In negative binomial hurdle models, the MMWR group showed fewer days of marijuana use at 3.5 months (B = -1.71, SE = 0.79, incidence rate ratio = 0.18, p = .030) and a trend at 7 months after the intervention (B = -0.90, standard error = 0.55, incidence rate ratio = 0.41, p = .10). For marijuana, mindfulness practice time during the intervention predicted time delay to first use (B = 0.28, p = .006) and total abstinence days (B = 0.34, p = .002) across the 7 months after MMWR. No other substance use outcomes showed differential response to MMWR relative to controls. Only in MMWR, number of study intervention sessions attended (dose) correlated with a greater length of time to alcohol intoxication (r = .48, p < .001), fewer days of alcohol intoxication (r = -.24, p = .020), and greater improvement in mindfulness skills (r = .61, p < .01).

CONCLUSIONS

MMWR added to an ongoing intensive residential treatment program serving vulnerable women is protective against marijuana use but no other substance use outcomes. Mindfulness practice time predicted a delay in time to first marijuana use. MMWR class attendance, an indicator of intervention dose, appears protective of alcohol intoxication at follow-up; thus, extended MMWR exposure might be useful.

The MET(T)A Protocol: Mindfulness and EMDR Treatment Template for Agencies

Evidence indicating the relationship between trauma and substance use disorders (SUDs), in addition to relapse and treatment retention rates for this population, suggests there is a need for a trauma-focused solution to treat SUDs. Eye movement desensitization and reprocessing (EMDR) therapy has been studied extensively as an effective approach for treating trauma and Posttraumatic Stress Disorder (PTSD). The research evaluating its treatment for other mental health disorders such as SUDs is promising. Merging mindfulness and ethical mindfulness practices with EMDR therapy lends additional evidence-based elements to make the case for this integrative system of treatment to be studied as a trauma-focused primary psychotherapy to treat SUDs. The resulting treatment, the MET(T)A Protocol (Mindfulness and EMDR Treatment Template for Agencies), has been created to address the need for a trauma-focused solution to treat SUDs. Procedures of the MET(T)A Protocol as applied in each of the 8 phases of EMDR therapy are described in detail. Clinical examples are provided to explain the application of the MET(T)A Protocol.

Disrupting the path to craving: Acting without awareness mediates the link between negative affect and craving

Low treatment utilization, relapse, and chronicity are characteristic of substance use disorders (SUDs). Craving is an important predictor of relapse. Individuals with an SUD report using various coping strategies in response to negative affect, two of which are investigated in the current study: suppression and acting with awareness. Suppression is typically understood to be avoidance of unwanted experience through turning attention away from unwanted stimuli. Acting with awareness (AWA) is a facet of mindfulness, which includes turning toward experience with kindness and curiosity, even when the experience is unwanted. Evidence suggests mindfulness may reduce craving, while suppression has been associated with increased craving. In the current study, participants (N = 210) had recently completed inpatient or intensive outpatient SUD treatment followed by a randomized controlled trial of aftercare. Participants completed measures within 2 weeks following the completion of the aftercare intervention. Negative affect and severity of dependence were both positively associated with craving. Structural equation modeling evaluated AWA and suppression as partial mediators of the link between negative affect and craving. Suppression was positively associated and AWA was negatively associated with craving. Mediation analyses revealed the indirect effect of negative affect on craving through AWA was significant, but the path through suppression was not. These findings suggest that AWA may inhibit the development of craving from negative affect, but further research is needed. Future research should investigate the path from negative affect to craving with greater temporal resolution to evaluate how these phenomena function with increased ecological validity.

Approach coping and substance use outcomes following mindfulness-based relapse prevention among individuals with negative affect symptomatology

Objectives

Mindfulness-based relapse prevention (MBRP) for substance use disorders (SUDs) appears to be particularly effective among individuals with high levels of co-occurring affective symptoms. We sought to understand whether changes in approach and avoidance coping may explain the effects of MBRP among this subpopulation.

Method

The sample included 286 individuals with SUDs randomized to MBRP, relapse prevention (RP), or treatment-as-usual (TAU) as an aftercare treatment. We conducted conditional indirect effect models with treatment condition as the predictor, baseline affective symptoms as the moderator, changes in approach and avoidance coping over time from baseline through 6-months post-treatment as mediators, and substance use and substance-related problems at 12-months post-treatment as the outcome. Affective symptomatology at baseline was modeled as a latent factor indicated by depression, anxiety, and PTSD symptoms. Change in approach and avoidance coping was modeled using latent growth curve analyses.

Results

We found significant conditional indirect effects of MBRP, such that the interaction of MBRP vs. TAU by affective symptoms predicted increases in approach coping, which in turn predicted fewer heavy drinking days and substance-related problems at month 12. Follow-up analyses showed that increases in approach coping mediated the therapeutic effect of MBRP on these outcomes among those with high, but not low or moderate, affective symptoms. We did not find indirect or conditional indirect effects when comparing RP to TAU, or when avoidance coping was the mediator.

Conclusions

The pronounced therapeutic effects of MBRP among individuals with SUD and relatively higher negative affective symptoms may be due to increases in approach coping over time.

The Role of Affect in Psychosocial Treatments for Substance Use Disorders

PURPOSE OF REVIEW

This paper provides a narrative review of studies published over the past five years that have examined the role of affect, including both affective symptoms and affective disorders, in psychosocial treatments for substance use disorder.

RECENT FINDINGS

A growing body of literature suggests that affective symptoms and affective disorders may moderate substance use disorder treatment efficacy, mediate the effects of treatment on substance use outcomes, and may be directly changed by substance use disorder treatment.

SUMMARY

Substance use disorders and affective disorders commonly co-occur, and both affect and affective disorders are associated with substance use disorder treatment outcomes. Future research should continue to examine affect as a moderator, mediator, and outcome of substance use disorder treatments. In particular, new studies that are designed to test precision medicine hypotheses would greatly expand our understanding of the role of affective symptoms and disorders in substance use disorder treatment.

Stress Allostasis in Substance Use Disorders: Promise, Progress, and Emerging Priorities in Clinical Research

Clinicians and researchers alike have long believed that stressors play a pivotal etiologic role in risk, maintenance, and/or relapse of alcohol and other substance use disorders (SUDs). Numerous seminal and contemporary theories on SUD etiology posit that stressors may motivate drug use and that individuals who use drugs chronically may display altered responses to stressors. We use foundational basic stress biology research as a lens through which to evaluate critically the available evidence to support these key stress-SUD theses in humans. Additionally, we examine the field's success to date in targeting stressors and stress allostasis in treatments for SUDs. We conclude with our recommendations for how best to advance our understanding of the relationship between stressors and drug use, and we discuss clinical implications for treatment development.

Socioeconomic status, mindfulness, and momentary associations between stress and smoking lapse during a quit attempt

BACKGROUND

Models of health disparities highlight stress among low socioeconomic status (SES) smokers as a barrier to cessation. Recent studies suggest that mindfulness may improve cessation outcomes by reducing stress during a quit attempt. The current study examined associations of SES and mindfulness with ecological momentary assessments (EMAs) of stress and smoking lapse during a quit attempt.

METHODS

EMAs (N = 32,329) were gathered from 364 smokers engaged in a quit attempt. A multilevel structural equation model estimated within person paths from momentary stress to subsequent smoking lapse. Between person paths estimated paths from a latent variable for SES and mindfulness to stress and smoking lapse, the indirect effect of SES and mindfulness on lapse through stress, and moderation of within person stress-lapse associations by SES and mindfulness.

RESULTS

Within person estimates found that momentary increases in stress predicted increased risk of subsequent smoking lapse. Between person estimates found that lower SES was indirectly associated with greater risk for smoking lapse through increased stress; and, higher mindfulness was indirectly associated with lower risk for smoking lapse through reduced stress. Additionally, higher SES participants, who reported lower stress during the quit attempt, showed a stronger relationship between momentary increases in stress and risk for subsequent smoking lapse.

CONCLUSIONS

Among low SES smokers engaged in a quit attempt, both SES and mindfulness uniquely influenced smoking lapse through their influence on stress. Findings support reports that mindfulness presents a promising intervention target to reduce stress and improve cessation outcomes among low SES smokers.

The Addictions Neuroclinical Assessment Negative Emotionality Domain Among Treatment-Seekers with Alcohol Use Disorder: Construct Validity and Measurement Invariance

BACKGROUND

The Addictions Neuroclinical Assessment (ANA), a framework for measuring heterogeneity in alcohol use disorder (AUD), focuses on 3 domains that reflect neurobiological dysfunction in addiction and correspond to the cycles of addiction: executive function, incentive salience, and negative emotionality. Kwako and colleagues (Am J Psychiatry 176:744, 2019) validated a 3-factor model of the ANA with neuropsychological and self-report indicators among treatment-seekers and non-treatment-seekers with and without AUD. The present analysis replicated and extended these findings in a treatment-seeking sample, focusing on the negative emotionality domain.

METHODS

Participants (n = 563; 58.8% male; mean age = 34.3) were part of a multisite prospective study of individuals entering AUD treatment. We examined the factor structure of the negative emotionality domain at the baseline, 6-month follow-up, and 12-month follow-up assessments. The Beck Depression Inventory, Beck Anxiety Inventory, State-Trait Anger Expression Inventory-Trait Anger Subscale, and 3 Drinker Inventory of Consequences items assessing negative affective consequences were indicators in the model.

RESULTS

Results indicated that a 1-factor model was an excellent fit at all assessments and that the negative emotionality domain was time and gender invariant. Furthermore, negative emotionality was associated with drinking patterns and reasons for alcohol use (i.e., drinking because of negative emotions and urges/withdrawal) at all assessments.

CONCLUSIONS

This analysis provides evidence for the construct validity and measurement invariance of the ANA negative emotionality domain among AUD treatment-seekers. Future studies are needed to evaluate prospective associations between negative emotionality and specific treatment modalities, and whether individuals with greater negative emotionality are more likely to respond to treatment that targets drinking to relieve negative affective states.

The relationship of mindfulness and mindfulness-related practices with alcohol use among Hispanics/Latinx

Hispanics/Latinx (H/Ls) are the largest ethnic minority group in the U.S., and three of the four leading causes of death are associated with problematic alcohol use. This study examined the relationship between mindfulness and alcohol use among H/Ls and whether differences emerged by sub-ethnicity. Participants (N = 341; 49.7% female; average age=28.57) were H/Ls currently living in the U.S. Survey questions were answered online in English or Spanish. Participants primarily endorsed engaging in informal mindfulness practices (47.5%), spiritual practices (25.2%), and mindfulness meditation (24.6%). No significant differences emerged among H/L sub-ethnicities. Spiritual practices and higher mindfulness were associated with less problematic alcohol use among the entire sample. Similar results were found among drinkers-only. Findings shed light on commonly used mindfulness practices and indicate that very few differences emerge among H/L sub-ethnicities on mindfulness practices and general mindfulness. The delivery/tailoring of mindfulness-based interventions (MBIs) may not need to differ amongst H/L sub-ethnicities in the U.S. Aspects of mindfulness appear protective regarding problematic alcohol use, suggesting that future MBIs that increase mindfulness should be explored for this population.

Spiritual experiences are related to engagement of a ventral frontotemporal functional brain network: Implications for prevention and treatment of behavioral and substance addictions

BACKGROUND AND AIMS

Spirituality is an important component of 12-step programs for behavioral and substance addictions and has been linked to recovery processes. Understanding the neural correlates of spiritual experiences may help to promote efforts to enhance recovery processes in behavioral addictions. We recently used general linear model (GLM) analyses of functional magnetic resonance imaging data to examine neural correlates of spiritual experiences, with findings implicating cortical and subcortical brain regions. Although informative, the GLM-based approach does not provide insight into brain circuits that may underlie spiritual experiences.

METHODS

Spatial independent component analysis (sICA) was used to identify functional brain networks specifically linked to spiritual (vs. stressful or neutral-relaxing) conditions using a previously validated guided imagery task in 27 young adults.

RESULTS

Using sICA, engagement of a ventral frontotemporal network was identified that was engaged at the onset and conclusion of the spiritual condition in a manner distinct from engagement during the stress or neutral-relaxing conditions. Degree of engagement correlated with subjective reports of spirituality in the scanner (r = .71, p < .001) and an out-of-the-magnet measure of spirituality (r = .48, p < .018).

DISCUSSION AND CONCLUSION

The current findings suggest a distributed functional neural network associated with spiritual experiences and provide a foundation for investigating brain mechanisms underlying the role of spirituality in recovery from behavioral addictions.

A pilot study of Vipassana meditation with female drug users at a rehabilitation centre, Thailand

Purpose

Substance abuse has become a major health issue in Thailand, contributing to high numbers of premature deaths and requiring considerable expenditure on treatment and rehabilitation programs. The purpose of this paper is to explore use of Vipassana meditation to reduce depression and improve empathy and self-awareness in drug dependent women at a rehabilitation centre.

Design/methodology/approach

Mixed methods were employed. Data were collected in a randomised controlled trial and focus group interviews with 24 intervention subjects and 22 controls.

Findings

Findings showed no significant differences in depression, empathy or mindfulness levels between intervention and control groups, but intervention subjects had a small decline in depression at one-month follow up. The focus group interviews showed that drug users had developed self-awareness, moral values and greater understanding of right and wrong acts.

Originality/value

Findings suggest that Vipassana meditation which is cultural appropriate for Thai culture and religion, should be incorporated into treatments in rehabilitation centres to increase successful outcomes.

Mindfulness Training plus Nature Exposure for Veterans with Psychiatric and Substance Use Disorders: A Model Intervention

There is a need to develop novel complementary interventions aimed at enhancing treatment engagement and/or response for veterans with psychiatric and substance use disorders. There is evidence that both mindfulness training and nature exposure (MT/NE) may be beneficial for this population and that combining the two approaches into one intervention might result in synergistic benefit. However, to date, the MT/NE concept has not been tested. This article reports a pilot feasibility and acceptability study of MT/NE which was, in this case, provided via recreational sailing. The primary aim of this project was to develop a model intervention and evaluation process that could be used for future studies of MT/NE interventions using a variety of methods of nature exposure (e.g., hiking, skiing, mountain biking). Results indicate preliminary evidence that it is feasible to utilize MT/NE interventions for the population studied and that the MT/NE model described can serve as a template for future investigations. Further, there were significant pre- to post-intervention decreases in state anxiety, as well as increases in trait mindfulness. Three psychological instruments were identified that might be used in future studies to evaluate MT/NE outcomes. Results from this project provide a model MT/NE intervention template along with evaluation metrics for use in future studies.
