Mindfulness-based treatment of addiction: current state of the field and envisioning the next wave of research

Virtual reality-based Mindfulness-Oriented Recovery Enhancement (MORE-VR) as an adjunct to medications for opioid use disorder: a Phase 1 trial

INTRODUCTION

Medications for opioid use disorder (MOUD) are the most effective interventions for this condition, yet many patients discontinue treatment. Though adjunct psychosocial treatments are recommended to increase retention and reduce relapse, the scarcity of trained providers hinders access to and utilization of evidence-based interventions. We conducted a Phase 1 study to assess the feasibility of a virtual reality-delivered Mindfulness-Oriented Recovery Enhancement (MORE-VR) intervention for patients receiving MOUD.

PATIENTS AND METHODS

Patients receiving buprenorphine or methadone for OUD (N = 34) were scheduled for 8 weekly sessions of MORE-VR. Enrollment and retention rates were analyzed. Participants reported on the usability and acceptability of MORE-VR, opioid use, and craving and affect before and after each VR session. Heart rate was monitored during one session of MORE-VR.

RESULTS

Twenty-three participants completed four or more MORE-VR sessions (minimum recommended intervention dose). Participants reported high usability and acceptability of MORE-VR, which had an excellent safety profile. Illicit opioid use decreased significantly from pre- to post-treatment (F = 4.44, p=.04). We observed a significant within-session decrease in opioid craving (F = 39.3, p<.001) and negative affect (F = 36.3, p<.001), and a significant within-session increase in positive affect (F = 23.6, p<.001). Heart rate shifted during cue-exposure and mindfulness practices (F = 6.79, p<.001).

CONCLUSIONS

High retention, usability and acceptability rates and low adverse events demonstrated that MORE-VR is a feasible, engaging, and safe intervention. Our findings show that MORE-VR can be delivered as an adjunctive intervention to MOUD and suggest that MORE-VR may improve OUD treatment outcomes and modulate autonomic responses. MORE-VR's efficacy will be tested in a subsequent Phase 2 trial.

Neuromodulation and meditation: A review and synthesis toward promoting well-being and understanding consciousness and brain

The neuroscience of meditation is providing insight into meditation's beneficial effects on well-being and informing understanding of consciousness. However, further research is needed to explicate mechanisms linking brain activity and meditation. Non-invasive brain stimulation (NIBS) presents a promising approach for causally investigating neural mechanisms of meditation. Prior NIBS-meditation research has predominantly targeted frontal and parietal cortices suggesting that it might be possible to boost the behavioral and neural effects of meditation with NIBS. Moreover, NIBS has revealed distinct neural signatures in long-term meditators. Nonetheless, methodological variations in NIBS-meditation research contributes to challenges for definitive interpretation of previous results. Future NIBS studies should further investigate core substrates of meditation, including specific brain networks and oscillations, and causal neural mechanisms of advanced meditation. Overall, NIBS-meditation research holds promise for enhancing meditation-based interventions in support of well-being and resilience in both non-clinical and clinical populations, and for uncovering the brain-mind mechanisms of meditation and consciousness.

Glutamate concentration of medial prefrontal cortex is inversely associated with addictive behaviors: a translational study

In both preclinical and clinical settings, dysregulated frontostriatal circuits have been identified as the underlying neural substrates of compulsive seeking/taking behaviors manifested in substance use disorders and behavioral addictions including internet gaming disorder (IGD). However, the neurochemical substrates for these disorders remain elusive. The lack of comprehensive cognitive assessments in animal models has hampered our understanding of neural plasticity in addiction from these models. In this study, combining data from a rat model of compulsive taking/seeking and human participants with various levels of IGD severity, we investigated the relationship between regional glutamate (Glu) concentration and addictive behaviors. We found that Glu levels were significantly lower in the prelimbic cortex (PrL) of rats after 20-days of methamphetamine self-administration (SA), compared to controls. Glu concentration after a punishment phase negatively correlated with acute drug-seeking behavior. In addition, changes in Glu levels from a drug naïve state to compulsive drug taking patterns negatively correlated with drug-seeking during both acute and prolonged abstinence. The human data revealed a significant negative correlation between Glu concentration in the dorsal anterior cingulate cortex (dACC), the human PrL counterpart, and symptoms of IGD. Interestingly, there was a positive correlation between Glu levels in the dACC and self-control, as well as mindful awareness. Further analysis revealed that the dACC Glu concentration mediated the relationship between self-control/mindful awareness and IGD symptoms. These results provide convergent evidence for a protective role of dACC/PrL in addiction, suggesting interventions to enhance dACC glutamatergic functions as a potential strategy for addiction prevention and treatment.

Strengthening Neuroplasticity in Substance Use Recovery Through Lifestyle Intervention

The incidence of substance use and behavioral addictions continues to increase throughout the world. The Global Burden of Disease Study shows a growing impact in disability-adjusted life years due to substance use. Substance use impacts families, communities, health care, and legal systems; yet, the vast majority of individuals with substance use disorders do not seek treatment. Within the United States, new legislation has attempted to increase the availability of buprenorphine, but the impact of substance use continues. Although medications and group support therapy have been the mainstay of treatment for substance use, lifestyle medicine offers a valuable adjunct therapy that may help strengthen substance use recovery through healthy neuroplastic changes.

Influence of physical activity on problematic smartphone use in medical students: mediating effects of social anxiety and the moderating role of gender

Objective

This study investigates the mediating role of social anxiety in the relationship between physical activity and problematic smartphone use among college students, and examines the moderating role of gender within this model.

Methods

From April to May 2023, a survey was conducted involving 2905 undergraduate students from various medical schools in Shandong, China. Participants completed the Physical Activity Rating Scale (PARS-3), Mobile Phone Addiction Tendency Scale for College Students (MPATS), and the Social Anxiety Scale (IAS). Descriptive statistics, correlation analysis, and hierarchical regression analysis and other methods were employed to explore the relationships between the variables. The mediating effect of social anxiety on physical activity and mobile phone addiction was assessed using the bootstrapping method, while the moderating role of gender on social anxiety and mobile phone addiction was evaluated using the PROCESS macro's model 14.

Results

The findings revealed that the scores of problematic smartphone use among medical students was 44.00 (35.00, 50.00), physical activity score was 16.00 (8.00, 32.00), and social anxiety score was 45.00 (42.00, 52.00). Physical activity was significantly and negatively correlated with both problematic smartphone use and social anxiety (P < 0.001), and social anxiety was significantly and positively correlated with problematic smartphone use (P < 0.001). Social anxiety partially mediated the effect between physical activity and problematic smartphone use (β = -0.04, 95%CI = -0.05 to -0.02), with a mediation effect proportion of 57.14%. Sex played a moderating role between social anxiety and problematic smartphone use (β = -0.30, 95%CI = -0.39 to -0.21).

Conclusion

Physical activity influences problematic smartphone use among medical students both directly and indirectly through social anxiety. Sex significantly moderates the influence of social anxiety on problematic smartphone use, highlighting the need for gender-specific interventions in this demographic.

Effects of physical activity and self-control on mobile phone addiction in college students: a cross-lagged study in China

Purpose

This study aims to investigate the impact of physical activity and self-control on college students' mobile phone addiction through cross-lagged longitudinal surveys, addressing the limitations of previous cross-sectional studies.

Patients and methods

A total of 414 college students were tracked three times during a 12-month period using the Physical Activity Rating Scale-3 (PARS-3), the Mobile Phone Addiction Tendency Scale (MPATS), and the Brief Self-Control Scale (BSCS). AMOS25.0 software was used to construct the cross-lagged relationship model, and the maximum likelihood approach was employed to investigate the model fitting. The asynchronous correlation between variables was investigated from the time series through the cross-lagged path coefficient.

Results

The fitting indexes of the cross-lagged model showed x 2/df = 5.098, GFI = 0.977, NFI = 0.969, IFI = 0.975, CFI = 0.974; RMSEA = 0.100, and SRMR = 0.030. The calculation conducted by combining the path coefficient of the model shows that PA and SC are the antecedent variables of MPA, and PA is the antecedent variable of SC. In addition, SC serves as a mediator in the path of PA, affecting MPA.

Conclusion

(1) physical activity can positively affect subsequent self-control; (2) physical activity can negatively influence subsequent mobile phone addiction; (3) self-control can negatively affect subsequent mobile phone addiction; and (4) physical activity can indirectly influence subsequent mobile phone addiction through self-control.

Behavioral therapies targeting reward mechanisms in substance use disorders

Behavioral therapies are considered best practices in the treatment of substance use disorders (SUD) and used as first-line approaches for SUDs without FDA-approved pharmacotherapies. Decades of research on the neuroscience of drug reward and addiction have informed the development of current leading behavioral therapies that, while differing in focus and technique, have in common the overarching goal of shifting reward responding away from drug and toward natural non-drug rewards. This review begins by describing key neurobiological processes of reward in addiction, followed by a description of how various behavioral therapies address specific reward processes. Based on this review, a conceptual 'map' is crafted to pinpoint gaps and areas of overlap, serving as a guide for selecting and integrating behavioral therapies.

Mindfulness programs for problematic usage of the internet: A systematic review and meta-analysis

Introduction

Problematic usage of the internet (PUI) is an umbrella term for a range of uncontrolled, excessive, and potentially harmful online behaviors. Recently, numerous studies have examined the potential of mindfulness programs (MPs) for reducing PUI. We conducted a comprehensive systematic review and meta-analysis in this emerging field.

Methods

We searched eight databases from inception to October 18, 2022, with no language restrictions. We included randomized controlled trials (RCTs) and nonrandomized trials (NRTs). The primary outcome was change in self-reported PUI, the secondary outcome was change in screen time.

Results

Of 3,473 identified records, 19 RCTs and 20 NRTs with a total of 1,549 participants were included. Participation in an MP was associated with large reductions in PUI in between-group analysis in RCTs (k = 19; g = -1.67; 95% CI -2.15, -1.19) and in within-group pre-post analysis in all studies (k = 35; g = -1.67; 95% CI -1.99, -1.36). Screen time showed a medium reduction in within-group pre-post analysis (k = 10; g = -0.65; 95% CI -0.90, -0.41). The effects for PUI remained significant in a series of sensitivity analyses, such as excluding low quality studies, excluding outliers, adjusting for publication bias, or using follow-up data. Heterogeneity between studies was high and the overall quality of evidence was rated low.

Discussion and conclusions

MPs are probably effective in reducing PUI and might be effective in reducing screen time. Shortcomings in the quality of evidence highlight the need for high-quality controlled trials with long-term follow-ups to confirm results.

[Substance use disorder: Epidemiology, medical consequences and treatment]

Substance use is a common health problem, and substance use disorder, which is its most severe presentation, is associated with multiple medical consequences and a negative impact on individual and on population health. Substance use disorder needs to be addressed as any chronic medical condition; therefore, it has to be detected at the early stages and has to be properly treated to prevent drug-related harm. Internists should be able to recognize and treat intoxication and abstinence. Internists should also be able to refer the patient to state of the art long term treatment, aimed to detoxification and treatment induction to promote abstinence and prevent relapse. In this narrative review we will discuss substance use epidemiology, its main medical consequences and its treatment, with a focus on alcohol, opiates, cocaine and other stimulants, cannabis and benzodiazepines.

Evaluating the effectiveness of a mobile app-based self-guided psychological interventions to reduce relapse in substance use disorder: protocol for a randomized controlled trial

Background

Substance Use Disorder (SUD) persists as a significant public health challenge worldwide, with an estimated prevalence of approximately 10-15% across the global populace. This condition is characterized by a notably high risk of lapses and relapses, even subsequent to treatment interventions. Mobile health interventions, owing to their widespread accessibility, emerge as a promising approach to diminish the risk of relapse post-treatment and to broaden the scope of care, especially in regions with a scarcity of trained medical professionals.

Method

This study is designed to assess the effectiveness of mobile interventions in mitigating cravings and preventing lapses among individuals diagnosed with SUD. Employing a two-armed, randomized controlled trial framework, the study will evaluate a self-administered psychological intervention delivered through a mobile application, Nałogometr 2.0. Over a period of three months, participants will engage with intervention modules that primarily incorporate mindfulness techniques and Cognitive Behavioral Therapy (CBT) principles. Ecological Momentary Assessment (EMA) will be utilized to gather longitudinal data on a range of variables that are indicative of craving intensity and the risk of lapse. In addition to this, a monthly-administered battery of questionnaires will be employed to gauge the severity of substance dependence, as well as to measure levels of anxiety, depression, and overall life satisfaction.

Results

Results will be submitted for publication in peer-reviewed journals.

The Effectiveness of Mindfulness in the Treatment of Methamphetamine Addiction Symptoms: Does Neuroplasticity Play a Role?

INTRODUCTION

Methamphetamine is a highly stimulating psychoactive drug that causes life-threatening addictions and affects millions of people around the world. Its effects on the brain are complex and include disturbances in the neurotransmitter systems and neurotoxicity. There are several known treatment methods, but their effectiveness is moderate. It must be emphasised that no drugs have been approved for treatment. For this reason, there is an urgent need to develop new, effective, and safe treatments for methamphetamine. One of the potential treatments is mindfulness meditation. In recent years, this technique has been researched extensively in the context of many neurological and psychiatric disorders.

METHODS

This review explores the use of mindfulness in the treatment of methamphetamine addiction. Searches were conducted in the PubMed/Medline, Research Gate, and Cochrane databases.

RESULTS

Ten studies were identified that used mindfulness-based interventions in the treatment of methamphetamine addiction. The results show that mindfulness is an effective form of reducing hunger, risk of relapses, stress indicators, depression, and aggression, alone or in combination with transcranial direct current stimulation (tDCS). Mindfulness also improved the cognitive function in addicts. The included studies used only behavioural measures. The potential mechanisms of mindfulness in addiction were explained, and it was proposed that it can induce neuroplasticity, alleviating the symptoms of addiction.

CONCLUSIONS

Evidence from the studies suggest that mindfulness may be an effective treatment option for methamphetamine addiction, used alone or in combination with tDCS. However, further high-quality research is required to establish the role of this treatment option in this field. The use of neuroimaging and neurophysiological measures is fundamental to understand the mechanisms of mindfulness.

Ten years of research on the treatments of internet gaming disorder: A scoping review and directions for future research

Background

Although internet gaming disorder (IGD) has been listed in section III of the DSM-5 for approximately 10 years, the study of treatments for IGD remains in early stages. Nonetheless, a summary of findings to date and discussion of future research needs are warranted.

Methods

The current study reviewed scientific treatment studies with control groups and randomized controlled trials. We summarized the strengths and weaknesses of different treatment strategies and identified gaps in the research literature that may inform the direction of future research efforts.

Results

Sixteen studies were reviewed. Existing treatment studies may be categorized into cognitive behavioural therapy (CBT), pharmacotherapies, non-invasive brain stimulation (NIBS), and others.

Conclusions

CBT is the most widely studied treatment strategy for IGD thus far. Future studies should consider IGD-specific CBT treatment strategies. Medication-based treatment should be implemented with caution. NIBS is promising, and future studies should explore the most efficacious parameters and targets. In addition, studies should consider sex differences in the treatment of IGD.

A call for mindfulness-based interventions for cannabis-use disorders

Cannabis use is being increasingly liberalized worldwide, and an increasing prevalence of cannabis-use disorder (CUD) is observed. The few current therapeutic options for CUD are only modestly effective. Mindfulness-based interventions offer promising prospects for the management of substance-use disorders. However, despite proliferating literature on mindfulness and substance use, few studies have explored mindfulness in terms of cannabis use and CUD. There are many possibilities for the implementation of mindfulness-based interventions for cannabis use reduction, especially for younger users, who are more vulnerable to cannabis-related harms. Accordingly, large controlled trials are needed to reliably assess the potential of such interventions.

Positive Psychology Intervention (PPI) Program for Persons Who Use Drugs (PWUDS): A Pilot Study

Building on the premises of Positive Psychology, this undertaking conducted a pilot study of the designed 14-session Positive Psychology Intervention (PPI) program established based on the character strengths and virtues (CSV) of persons who use drugs (PWUDs) to assess its usefulness, delivery details, and impacts. Conducted in one of the biggest Drug Abuse Treatment and Rehabilitation Center in the Philippines, 24 PWUDs were randomly selected by the program staff to participate in its pilot run while securing all necessary ethical guidelines and requirements. Via within-subjects pretest-posttest experimental design, the especially adapted and developed tools were used to assess the PWUDs' progress as they were facilitated by the said program. Results yielded significant improvements in the PWUDs' mental wellbeing (M = 1.29, SD = 0.35; t(21) = 9.30, P < .00001), life satisfaction (M = 1.82, SD = 0.24; t(21) = 9.89, P < .00001), and psychological functioning (M = 1.65, SD = 0.19; t(21) = 8.58, P < .00001). Moreover, the PWUDs regarded the designed PPI program very highly and experienced it with positive outcomes, especially for their CSVs. Further improvement of the said program centers around proper time allotment, number of participants in the program sessions, appropriate activities per session, including specific ice breaker games, activity materials needed, and the proper sequencing of each session. These data are used to improve the PPI program structures and components. Pertinent conclusions about the gathered data were drawn, and relevant recommendations were also thereby provided.

Mindfulness meditation and psychedelics: potential synergies and commonalities

There has been increasing scientific and clinical interest in studying psychedelic and meditation-based interventions in recent years, both in the context of improving mental health and as tools for understanding the mind. Several authors suggest neurophysiological and phenomenological parallels and overlaps between psychedelic and meditative states and suggest synergistic effects of both methods. Both psychedelic-assisted therapy and meditation training in the form of mindfulness-based interventions have been experimentally validated with moderate to large effects as alternative treatments for a variety of mental health problems, including depression, addictions, and anxiety disorders. Both demonstrated significant post-acute and long-term decreases in clinical symptoms and enhancements in well-being in healthy participants, in addition. Postulated shared salutogenic mechanisms, include, among others the ability to alter self-consciousness, present-moment awareness and antidepressant action via corresponding neuromodulatory effects. These shared mechanisms between mindfulness training and psychedelic intervention have led to scientists theorizing, and recently demonstrating, positive synergistic effects when both are used in combination. Research findings suggest that these two approaches can complement each other, enhancing the positive effects of both interventions. However, more theoretical accounts and methodologically sound research are needed before they can be extended into clinical practice. The current review aims to discuss the theoretical rationale of combining psychedelics with mindfulness training, including the predictive coding framework as well as research findings regarding synergies and commonalities between mindfulness training and psychedelic intervention. In addition, suggestions how to combine the two modalities are provided.

Integrated Alcohol Use and Sexual Assault Prevention Program for College Men Who Engage in Heavy Drinking: Randomized Pilot Study

BACKGROUND

Sexual assault is prevalent on college campuses and most commonly is perpetrated by men. Problematically, there is a dearth of evidence-based prevention programs targeting men as perpetrators of sexual aggression. The Sexual Assault and Alcohol Feedback and Education (SAFE) program is an integrated alcohol and sexual assault prevention intervention for college men who engage in heavy drinking that aims to address sexual aggression proclivity and alcohol use outcomes by incorporating social norms theory, bystander intervention, and motivational interviewing.

OBJECTIVE

This study aims to examine the initial feasibility-, acceptability-, and efficacy-related outcomes of a randomized pilot trial of an integrated alcohol and sexual assault prevention program for college men who engage in heavy drinking.

METHODS

This study included 115 college men who engaged in heavy drinking, who were randomly assigned to the SAFE program or a mindfulness-based control condition (MBCC). The feasibility of implementation, adequacy of participant retention, fidelity and competency of program administration, and satisfaction and utility of the intervention were evaluated. The primary outcomes of alcohol use and sexual aggression were evaluated at 2 and 6 months after baseline. The secondary outcomes of perceived peer norms, risks for sexual aggression, and bystander intervention were also assessed. The extent to which the motivational interviewing session with personalized normative feedback facilitated changes in the proximal outcomes of drinking intentions, motivation to change, and self-efficacy was also examined.

RESULTS

The study procedures resulted in high program completion and retention (>80%), high fidelity to the program manual (>80% of the content included), high competency in program administration, and high ratings of satisfaction and program utility in addressing sexual relationships and alcohol use. Both groups reported declines in the number of drinks per week and number of heavy drinking days. Compared with the MBCC participants, the SAFE participants reported higher motivation to change alcohol use after the program, as well as greater use of alcohol protective behavioral strategies at 6 months. Compared with the MBCC participants, the SAFE participants also reported lower perceived peer engagement in sexual coercion, perceived peer comfort with sexism, and peer drinking norms at 2 and 6 months. However, no group differences were observed in sexual aggression severity, rape myth acceptance, or the labeling of sexual consent. Results regarding bystander intervention intentions were mixed, with the MBCC group showing decreased intentions at 2 months and the SAFE group reporting increased intentions at both 2 and 6 months.

CONCLUSIONS

The findings provide promising evidence for the feasibility, acceptability, utility, and preliminary efficacy of the SAFE program in reducing alcohol use and positively influencing perceived peer norms and intentions for bystander intervention among college men who drink.

Be more mindful: Targeting addictive responses by integrating mindfulness with cognitive bias modification or cue exposure interventions

This review provides an overview of the most prominent neurocognitive effects of cognitive bias modification (CBM), cue-exposure therapy and mindfulness interventions for targeting addictive responses. It highlights the key insights that have stemmed from cognitive neuroscience and brain imaging research and combines these with insights from behavioural science in building a conceptual model integrating mindfulness with response-focused CBM or cue-exposure interventions. This furthers our understanding of whether and how mindfulness strategies may i) facilitate or add to the induced response-focused effects decreasing cue-induced craving, and ii) further weaken the link between craving and addictive responses. Specifically, awareness/monitoring may facilitate, and decentering may add to, response-focused effects. Combined awareness acceptance strategies may also diminish the craving-addiction link. The conceptual model presented in this review provides a specific theoretical framework to deepen our understanding of how mindfulness strategies and CBM or cue-exposure interventions can be combined to greatest effect. This is important in both suggesting a roadmap for future research, and for the further development of clinical interventions.

Mindfulness as an early intervention for hazardous alcohol use among non-treatment seeking Latine emerging adults: A mini-review

The age cohort referred to as emerging adults (ages 18-29 years old) demonstrates the most hazardous alcohol use in the United States (U.S.) Approximately one-third of emerging adults regularly engage in heavy episodic drinking (4/5 drinks in two hours females/males). Compared to their non-Latine White peers, Latine emerging adults in the U.S. report lower rates of heavy episodic drinking (HED) yet are at greater risk of developing a substance use disorder and experience more severe negative consequences from drinking alcohol. Despite their high-risk status, Latine emerging adults are less likely to seek treatment and have less access to innovative health-promoting resources, further exacerbating health inequities. Research has shown that practicing mindfulness can interrupt habituated cognitions, intrusive thinking, and automatic behaviors associated with hazardous drinking. However, Latine representation in MBI trials is minimal. This mini-review explores the potential value of mindfulness as an early intervention for hazardous alcohol use among Latine emerging adults. The review provides future directions for research, highlighting the need to design culturally and developmentally tailored MBIs that can provide a respectful, non-judgmental, and discrimination-free environment that appeals to Latine emerging adults. Additionally, conclusions are drawn regarding the possible benefits of pairing MBI with contingency management strategies to decrease attrition rates in MBI trials.

Psychosocial-spiritual well-being is related to resilience and mindfulness in patients with severe and/or life-limiting medical illness

BACKGROUND

Improvement of psychosocial-spiritual well-being in patients with life-threatening or life-limiting illness is desirable. Resilience and mindfulness are considered to be helpful for enhancing psychosocial-spiritual well-being. Mindfulness-based interventions have been shown to promote resilience to stress and enhance well-being. However, in medical patients, evidence for the associations between mindfulness and resilience is lacking. We hypothesize patients with higher levels of psychosocial-spiritual well-being demonstrate greater resilience and mindfulness.

METHODS

200 patients (mean age = 50.2, SD = 15.5) with serious and or life-limiting illnesses were recruited from the NIH Clinical Center. Patients completed a demographic questionnaire, the NIH-HEALS measure of psychosocial-spiritual well-being, the Connor-Davidson Resilience Scale (CD-RISC-10), and the Mindful Attention Awareness Scale (MAAS). The demographic questionnaire also included a question on current stress level.

RESULTS

The NIH-HEALS was positively correlated to CD-RISC-10 (rs=0.44, p < 0.001) and MAAS (rs=0.32, p < 0.001). These findings were consistent across all three NIH-HEALS factors. Additionally, CD-RISC-10 and MAAS demonstrated a meaningful relationship to each other (rs=0.46, p < 0.001). All three constructs were inversely related to current stress level.

CONCLUSIONS

Findings suggest that there is a meaningful relationship between psychosocial-spiritual well-being, mindfulness, and resilience. Mindfulness and resilience are positively correlated in a medical population. Clinical interventions aimed at enhancing psychosocial-spiritual well-being through mindfulness and resilience can be highly promising for patients with severe and or life limiting illness.

Toward personalized circuit-based closed-loop brain-interventions in psychiatry: using symptom provocation to extract EEG-markers of brain circuit activity

Symptom provocation is a well-established component of psychiatric research and therapy. It is hypothesized that specific activation of those brain circuits involved in the symptomatic expression of a brain pathology makes the relevant neural substrate accessible as a target for therapeutic interventions. For example, in the treatment of obsessive-compulsive disorder (OCD), symptom provocation is an important part of psychotherapy and is also performed prior to therapeutic brain stimulation with transcranial magnetic stimulation (TMS). Here, we discuss the potential of symptom provocation to isolate neurophysiological biomarkers reflecting the fluctuating activity of relevant brain networks with the goal of subsequently using these markers as targets to guide therapy. We put forward a general experimental framework based on the rapid switching between psychiatric symptom states. This enable neurophysiological measures to be derived from EEG and/or TMS-evoked EEG measures of brain activity during both states. By subtracting the data recorded during the baseline state from that recorded during the provoked state, the resulting contrast would ideally isolate the specific neural circuits differentially activated during the expression of symptoms. A similar approach enables the design of effective classifiers of brain activity from EEG data in Brain-Computer Interfaces (BCI). To obtain reliable contrast data, psychiatric state switching needs to be achieved multiple times during a continuous recording so that slow changes of brain activity affect both conditions equally. This is achieved easily for conditions that can be controlled intentionally, such as motor imagery, attention, or memory retention. With regard to psychiatric symptoms, an increase can often be provoked effectively relatively easily, however, it can be difficult to reliably and rapidly return to a baseline state. Here, we review different approaches to return from a provoked state to a baseline state and how these may be applied to different symptoms occurring in different psychiatric disorders.

Incidence of stroke and its predictors among hypertensive patients in Felege Hiwot comprehensive specialized hospital, Bahir Dar, Ethiopia, a retrospective follow-up study

BACKGROUND

Globally, one in three adults has hypertension, a condition that causes 51% of all deaths from stroke. Stroke is becoming a major public health problem and the most common cause of morbidity and mortality among non-communicable diseases in the world and Ethiopia. Therefore, this study assesses the incidence of stroke and its predictors among hypertensive patients in Felege Hiwot Comprehensive Specialized Hospital, Bahir Dar, Ethiopia 2021.

METHODS

A hospital-based retrospective follow-up study design was used, simple random sampling technique was used to select 583 hypertensive patients that had follow-up registration between January 2018 and December 30th, 2020. Data were entered into Epi-data version 3.1 and exported to STATA version 14. The adjusted hazard ratio for each predictor with a 95% confidence interval was calculated using the Cox proportional hazards regression model, and a P-value ≤  0.05 was used to denote statistical significance.

RESULTS

From 583 hypertensive patients 106(18.18%) [95% CI 15-20] were developed stroke. The overall incidence rate was 1 per 100 person-years (95% CI 0.79-1.19). Comorbidities (Adjusted hazard ratio(AHR): 1.88, 95% CI 1.0-3.5), stage two hypertension (AHR = 5.21, 95%CI 2.75-9.8), uncontrolled systolic blood pressure (AHR: 2, 95% CI 1.21-354), uncontrolled diastolic blood pressure (AHR:1.9, 95% CI 1.1-3.57), alcohol consumption (AHR = 2.04, 95%CI 1.2-3.49), age 45-65 (AHR = 10.25, 95%CI 7.47-11.1); and drug discontinuation (AHR = 2.05,95% CI 1.26-3.35) were independent predictors for the incidence of stroke among hypertensive patients.

CONCLUSION

The incidence of stroke among hypertensive patients was high and various modifiable and non-modifiable risk factors highly contributed to its incidence. This study recommends early screening of blood pressure, giving priority to comorbid patients and patients with advanced stage hypertension, and giving health education about behavioral risks and drug adherence.

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.

Primary Care at the Intersection of Lifestyle Interventions and Unhealthy Substance Use

Primary care physicians are well-positioned to integrate lifestyle interventions into the management of patients with unhealthy substance use, who may also have mental and physical chronic health comorbidities. However, the COVID-19 pandemic exacerbated the U.S.'s poor state of health, revealing that its current approach to chronic disease management is neither effective nor sustainable. Today's full spectrum comprehensive care model requires an expanded toolkit. Lifestyle interventions broaden current treatment approaches and may enhance Addiction Medicine care. Primary care providers have the potential to have the greatest impact on unhealthy substance use care because they are experts in chronic disease management and their frontline accessibility minimizes healthcare barriers. Individuals with unhealthy substance use are at an increased risk of chronic physical conditions. Incorporating lifestyle interventions with unhealthy substance use care at every level of medicine, from medical school through practice, normalizes both as part of the standard care of medicine and will drive evidence-based best practices to support patients through prevention, treatment, and reversal of chronic diseases.

The Craving-Manager smartphone app designed to diagnose substance use/addictive disorders, and manage craving and individual predictors of relapse: a study protocol for a multicenter randomized controlled trial

Background

The rate of individuals with addiction who are currently treated are low, and this can be explained by barriers such as stigma, desire to cope alone, and difficulty to access treatment. These barriers could be overcome by mobile technologies. EMI (Ecological Momentary Intervention) is a treatment procedure characterized by the delivery of interventions (messages on smartphones) to people in their daily lives. EMI presents opportunities for treatments to be available to people during times and in situations when they are most needed. Craving is a strong predictor of relapse and a key target for addiction treatment. Studies using Ecological Momentary Assessment (EMA) method have revealed that, in daily life, person-specific cues could precipitate craving, that in turn, is associated with a higher probability to report substance use and relapse in the following hours. Assessment and management of these specific situations in daily life could help to decrease addictive use and avoid relapse. The Craving-Manager smartphone app has been designed to diagnose addictive disorders, and assess and manage craving as well as individual predictors of use/relapse. It delivers specific and individualized interventions (counseling messages) composed of evidence-based addiction treatments approaches (cognitive behavioral therapy and mindfulness). The Craving-Manager app can be used for any addiction (substance or behavior). The objective of this protocol is to evaluate the efficacy of the Craving-Manager app in decreasing use (of primary substance(s)/addictive behavior(s)) over 4 weeks, among individuals on a waiting list for outpatient addiction treatment.

Methods/design

This multicenter double-blind randomized controlled trial (RCT) will compare two parallel groups: experimental group (full interventional version of the app, 4 weeks, EMA + EMI), versus control group (restricted version of the app, 4 weeks, only EMA). Two hundred and seventy-four participants will be recruited in 6 addiction treatment centers in France.

Discussion

This RCT will provide indication on how the Craving-Manager app will reduce addictive use (e.g., better craving management, better stimulus control) in both substance and behavioral addictions. If its efficacy is confirmed, the app could offer the possibility of an easy to use and personalized intervention accessible to the greatest number of individuals with addiction.

Staying with the silence: Silence as affording care in online alcohol and other drug counselling

As the name 'talk therapy' suggests, a key aim of alcohol and other drug counselling, psychotherapy and other talk therapies is to discuss issues, concerns and feelings with a health professional. Implicit here is the therapeutic value of talking through issues with a trained professional. But as with all interactions, therapeutic encounters involve silences and pauses as key aspects of the communicative process. Despite their ubiquity in the therapeutic encounter, research tends to either dismiss silences as inconsequential or as having undesirable effects, such as generating awkwardness or even disengagement from treatment. Drawing on Latour's (2002) concept of 'affordance' and a qualitative study of an Australian alcohol and other drug counselling service, we explore the varied functions of silences in online text-based counselling sessions. For clients, these include the role of silence in affording opportunities to engage in other everyday practices, such as socialising, caregiving or working - practices that can generate comfort and reduce distress, which in turn may support the therapeutic encounter. Similarly, for counsellors, temporal silences provide opportunities to confer with other counsellors and provide tailored care. However, protracted silences can raise concerns about the safety and wellbeing of clients who do not respond promptly or who exit encounters unexpectedly. Similarly, the sudden cessation of online care encounters (often associated with technical difficulties) can leave clients feeling frustrated and confused. In tracking these diverse affordances of silence, we draw attention to its generative potential in care encounters. We conclude by exploring the implications of our analysis for conceptions of care that underpin alcohol and other drug treatment.

Examining neurobehavioral differences that support success in recovery from alcohol and other substance use disorders

OBJECTIVE

Substance use disorders (SUDs) are brain disorders associated with impairments resulting from the recurrent use of alcohol, drugs, or both. Though recovery is possible, SUDs are chronic, relapsing-remitting disorders, with estimates of SUD relapse at 40-60%. Currently, we know little about the mechanisms underlying successful recovery processes and whether substance-specific mechanisms exist. The current study sought to examine delay discounting (a measure of future valuation), executive skills, abstinence duration, and health behaviors in a population of individuals in recovery from alcohol, stimulants, opioids, and other substances.

METHODS

In this observational study, we utilized a cohort of individuals (n = 238) from the International Quit and Recovery Registry, an online registry for those in recovery from SUDs around the world. We assessed delay discounting through a neurobehavioral task, and assessed abstinence duration, executive skills, and engagement in positive health behaviors through self-report measures.

RESULTS

We found that delay discounting, executive skills, and engagement in positive health behaviors were similar among individuals in recovery from different substances. Abstinence duration was associated with delay discounting and engagement in health behaviors. Additionally, executive skills and engagement in health behaviors were positively associated.

CONCLUSION

These findings suggest that common behavioral mechanisms support recovery from misuse of various substances. As both delay discounting and executive skills are dependent upon executive brain centers, such as the prefrontal cortex, strategies that target executive functioning, such as episodic future thinking, meditation, or exercise, may be efficient strategies for optimizing recovery from SUDs.

Exploring potential moderators of depressive symptoms and treatment outcomes among patients with opioid use disorder

BACKGROUND

Depressive symptoms are common in patients seeking medication treatment for opioid use disorder (MOUD treatment) and decrease quality of life but have been inconsistently related to opioid treatment outcomes. Here, we explore whether depressive symptoms may only be related to adverse treatment outcomes among individuals reporting high opioid use-related coping motives (i.e., use of opioids to change affective states) and high trait impulsivity, two common treatment targets.

METHODS

Patients seeking MOUD treatment (N = 118) completed several questionnaires within two weeks of their treatment intake. Treatment outcomes (opioid-positive urine screens and days retained in treatment) were extracted from treatment records. Moderation analyses controlling for demographic characteristics and main effects were conducted to explore interaction effects between depressive symptoms and two distinct moderators.

RESULTS

Depressive symptoms were only related to opioid use during early treatment among patients reporting high opioid use-related coping motives (B = 2.67, p =.004) and patients reporting high trait impulsivity (B = 2.01, p =.039). Further, depressive symptoms were only inversely related to days retained among individuals with high opioid use-related coping motives (B = -10.12, p =.003).

CONCLUSIONS

Individuals presenting to treatment with opioid-related coping motives and/or impulsivity in the context of depressive symptoms may confer unique risk for adverse treatment outcomes. Clinicians may wish to consider these additive risk factors when developing their treatment plan.

Interoception Within the Context of Impulsivity and Addiction

Purpose of Review

The goal of this review is to examine the relationship between impulsivity and interoception in addiction, to summarize the current understanding of the topic, identify any gaps in knowledge, and provide directions for future research.

Research Findings

Interoception may be a contributing factor to impulsive behaviour and, thus, addiction. Substance abuse can negatively impact the brain's ability to process interoceptive information and impact the reward system, leading to decreased sensitivity to natural rewards and increased sensitivity to drugs. There is potential for new therapies, such as mindfulness, interoceptive training, brain stimulation, or vagal nerve stimulation to target both impulsivity and interoception in the treatment of addiction.

Summary

Despite a growing interest in interoception in addiction research, further research is needed to better understand the role of interoception in addiction and to develop new methods for studying how individuals with addiction process and perceive internal bodily sensations.

The Evolution of Telepsychiatry for Substance Use Disorders During COVID-19: a Narrative Review

Purpose of Review

This article aims to review and synthesize the current research evidence regarding the efficacy of telepsychiatry-delivered substance use disorder treatment using a narrative review with a focus on the effects of remote healthcare delivery within the substance abuse treatment space.

Recent Findings

The COVID-19 pandemic exerted substantial pressures on all levels of society. Social isolation, loss of employment, stress, physical illness, overburdened health services, unmet medical needs, and rapidly changing pandemic restrictions had particularly severe consequences for people with mental health issues and substance use disorders. Since the start of the pandemic, addiction treatment (and medical treatment overall) using remote health platforms has significantly expanded to different platforms and delivery systems. The USA, in particular, reported transformational policy developments to enable the delivery of telehealth during the COVID-19 pandemic. However, systemic barriers such as a widespread lack of internet access and insufficient patient and provider digital skills remain.

Summary

Overall, telepsychiatry is a promising approach for the treatment of substance use disorders, but more randomized controlled trials are needed in the future to assess the evidence base of available interventions.

Culturally adapted motivational interviewing with cognitive behavior therapy and mindfulness-based relapse prevention for substance use disorder in Pakistan (CAMAIB): protocol for a feasibility factorial randomised controlled trial

BACKGROUND

The use of psychoactive substances significantly impacts the health, social and economic aspects of families, communities and nations. There is a need to develop and test psychological interventions aimed for individuals with substance use disorder (SUD) in lower- and middle-income countries (LMICs), such as in Pakistan. The aim of this exploratory trial is to test the feasibility and acceptability of two culturally adapted psychological interventions in a factorial randomised controlled trial (RCT).

METHODS

The proposed project will be conducted in three phases. The first phase of the study will focus on cultural adaptation of the interventions through qualitative interviews with key stakeholders. The second phase will be to refine and produce manually assisted interventions. Third and last stage would be to assess the feasibility of the culturally adapted interventions through a factorial RCT. The study will be carried out in Karachi, Hyderabad, Peshawar, Lahore and Rawalpindi, Pakistan. Recruitment of participants will take place from primary care and volunteer organisations/drug rehabilitation centres. A total of 260 individuals diagnosed with SUD (n = 65) in each of the four arms will be recruited. The intervention will be delivered weekly over a period of 12 weeks in both individual and group settings. Assessments will be carried out at baseline, at 12th week (after completion of intervention) and 24th week post-randomisation. The analysis will determine the feasibility of recruitment, randomisation, retention and intervention delivery. Acceptability of intervention will be determined in terms of adherence to intervention, i.e. the mean number of sessions attended, number of home assignments completed, attrition rates, as well as through process evaluation to understand the implementation process, context, participants' satisfaction, and impact of the study intervention. The health resource use and impact on the quality of life will be established through health economic data.

DISCUSSION

This study will provide evidence for feasibility and acceptability of culturally adapted manually assisted psychological interventions for individuals with SUD in the context of Pakistan. The study will have clinical implications if intervention is proven feasible and acceptable.

A randomised controlled feasibility study of food-related computerised attention training versus mindfulness training and waiting-list control for adults with overweight or obesity: the FOCUS study

BACKGROUND

In a feasibility randomised controlled trial in people with overweight/obesity with and without binge eating disorder (BED) symptoms, we assessed eight weekly sessions of attention bias modification training (ABMT) and mindfulness training (MT) versus waiting list (WL) and explored potential mechanisms.

METHODS

45 participants were randomly allocated to one of three trial arms. Primary outcomes were recruitment, retention and treatment adherence rates. Secondary outcomes included measures of eating behaviour, mood, attention and treatment acceptability. Assessments were conducted at baseline, post-intervention (week 8), and follow-up (week 12).

RESULTS

Participant retention at follow-up was 84.5% across groups. Session completion rates in the laboratory were 87% for ABMT and 94% for MT, but home practice was much poorer for ABMT. Changes in BMI and body composition were small between groups and there was a medium size BMI reduction in the MT group at follow-up. Effect sizes of eating disorder symptom changes were not greater for either intervention group compared to WL, but favoured ABMT compared to MT. Hedonic hunger and mindful eating scores favoured MT compared to ABMT and WL. ABMT reduced attention biases towards high-calorie food cues, which correlated with lower objective binge eating days at post-intervention. No significant changes were observed in the MT, or WL conditions.

CONCLUSIONS

Both ABMT and MT have potential value as adjuncts in the treatment of obesity and BED, and a larger clinical trial appears feasible and indicated.

Adaptive interventions for opioid prescription management and consumption monitoring

OBJECTIVES

While opioid addiction, treatment, and recovery are receiving attention, not much has been done on adaptive interventions to prevent opioid use disorder (OUD). To address this, we identify opioid prescription and opioid consumption as promising targets for adaptive interventions and present a design framework.

MATERIALS AND METHODS

Using the framework, we designed Smart Prescription Management (SPM) and Smart Consumption Monitoring (SCM) interventions. The interventions are evaluated using analytical modeling and secondary data on doctor shopping, opioid overdose, prescription quality, and cost components.

RESULTS

SPM was most effective (30-90% improvement, for example, prescriptions reduced from 18 to 1.8 per patient) for extensive doctor shopping and reduced overdose events and mortality. Opioid adherence was improved and the likelihood of addiction declined (10-30%) as the response rate to SCM was increased. There is the potential for significant incentives ($2267-$3237) to be offered for addressing severe OUD.

DISCUSSION

The framework and designed interventions adapt to changing needs and conditions of the patients to become an important part of global efforts in preventing OUD. To the best of our knowledge, this is the first paper on adaptive interventions for preventing OUD by addressing both prescription and consumption.

CONCLUSION

SPM and SCM improved opioid prescription and consumption while reducing the risk of opioid addiction. These interventions will assist in better prescription decisions and in managing opioid consumption leading to desirable outcomes. The interventions can be extended to other substance use disorders and to study complex scenarios of prescription and nonprescription opioids in clinical studies.

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.

Individually delivered mindfulness-based cognitive therapy in concomitant problematic substance use and emotional symptoms: A process-based case study

The process-based approach assumes that transdiagnostic psychological processes are involved in the onset and maintenance of mental disorders. Case conceptualization is used to identify such psychological processes and to individualize the intervention accordingly. This approach is fundamentally different from syndrome-based approaches in which standardized treatments are administered for psychiatric diagnoses or symptoms. In the current case, we proposed a process-based conceptualization and treatment for a woman with concomitant problematic substance use and emotional symptoms. Our idiosyncratic process-based conceptualization showed that for this person, substance abuse consisted in a maladaptive coping strategy to deal with repetitive negative thinking and poor emotion regulation skills, for which we decided to use a mindfulness-based intervention. Treatment comprised 8 weeks of individually delivered mindfulness-based cognitive therapy sessions. A comprehensive assessment of psychiatric symptoms and psychological processes was conducted at baseline, post-intervention and 3-month follow-up. The post-treatment assessment revealed that psychological processes targeted by the intervention were improved, together with the mindfulness trait. At the symptom-based level, we observed a significant reduction in substance abuse and emotional symptoms. Treatment gains were maintained at follow-up. From a process-based perspective, this result implies that the intervention successfully targeted the psychological processes underlying the presenting symptoms. Adopting a process-based approach rather than symptom- or syndrome-based approaches is a valuable alternative in the conceptualization and treatment of complex cases presenting with multiple comorbidities.

Reducing craving and lapse risk in alcohol and stimulants dependence using mobile app involving ecological momentary assessment and self-guided psychological interventions: Protocol for a randomized controlled trial

Background

The prevalence of alcohol consumption in Poland is estimated to be as high as 80% of the adult population. The use of stimulants is the second most common reason for seeking addiction treatment. However, treatment outcomes remain unsatisfactory, as 40-85% of individuals who complete various treatment programs relapse and fall back into addiction within 2 years following program completion.

Methods

The 13-armed randomized controlled trial aimed to assess the effectiveness of a mobile app-based self-guided psychological intervention delivered via a smartphone app (Nałogometr) in reducing craving and lapse risk in problematic alcohol or stimulants use. Participant recruitment and data collection will be performed from June 2022 to September 2022. The 4-week mobile intervention program will include short-term and long-term intervention modules based mainly on mindfulness and cognitive-behavioral therapy. Intervention effectiveness assessment will include Ecological Momentary Assessment. That is, we will collect longitudinal data on a set of characteristics of day-to-day functioning. The primary outcomes will include a self-reported number of lapses and addiction craving level. In contrast, the secondary outcomes will be the severity of problematic substance use, anxiety and depression scores, and life satisfaction scores.

Conclusion

This study will establish how mobile app-based self-guided psychological interventions can help reduce craving and lapse risk in alcohol and stimulant dependence. If successful, this randomized controlled trial (RCT) may provide an innovative, easily available, and cost-effective mHealth approach for craving and lapse risk in substance addictions.

The Treatment of Substance Use Disorders: Recent Developments and New Perspectives

Substance-related disorders are complex psychiatric disorders that are characterized by continued consumption in spite of harmful consequences. Addiction affects various brain networks critically involved in learning, reward, and motivation, as well as inhibitory control. Currently applied therapeutic approaches aim at modification of behavior that ultimately leads to decrease of consumption or abstinence in individuals with substance use disorders. However, traditional treatment methods might benefit from recent neurobiological and cognitive neuroscientific research findings. Novel cognitive-behavioral approaches in the treatment of addictive behavior aim at enhancement of strategies to cope with stressful conditions as well as craving-inducing cues and target erroneous learning mechanisms, including cognitive bias modification, reconsolidation-based interventions, mindfulness-based interventions, virtual-reality-based cue exposure therapy as well as pharmacological augmentation strategies. This review discusses therapeutic strategies that target dysregulated neurocognitive processes associated with the development and maintenance of disordered substance use and may hold promise as effective treatments for substance-related disorders.

Effects of a trauma‐informed mindful recovery program on comorbid pain, anxiety, and substance use during primary care buprenorphine treatment: A proof‐of‐concept study

BACKGROUND

A mindfulness-based intervention that reduces comorbid pain, anxiety, and substance use during office-based opioid treatment (OBOT) could enhance retention and prevent overdose. We conducted a pilot study of the Mindful Recovery OUD Care Continuum (M-ROCC), a 24-week trauma-informed program with a motivationally-sensitive curriculum.

METHODS

Patients prescribed buprenorphine (N = 18) enrolled in M-ROCC. We collected urine toxicology biweekly. At 0, 4, and 24 weeks, participants completed PROMIS-Pain, PROMIS-Anxiety, Mindfulness (FFMQ), Experiential Avoidance (BEAQ), Interoceptive Awareness (MAIA), and Self-Compassion (SCS-SF) scales. We estimated changes over time using mixed models. Participants completed qualitative interviews at 4 and 24 weeks.

RESULTS

Positive urine toxicology decreased over time for cocaine (β = -.266, p = .008) and benzodiazepines (β = -.208, p = .028). M-ROCC reduced PROMIS-Pain (Z = -2.29; p = .022), BEAQ (Z = -2.83; p = .0005), and increased FFMQ (Z = 3.51; p < .001), MAIA (Z = 3.40; p = .001), and SCS-SF (Z = 2.29; p = .022). Participants with co-morbid anxiety had decreased PROMIS-Anxiety (Z = -2.53; p = .012). Interviewed participants commonly used mindfulness practices for stress and anxiety (12/12, 100%), and to reduce pain catastrophizing and rumination (7/12, 58%).

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

This is the first study to report the effects of a 24-week mindfulness program during buprenorphine treatment on common comorbidities, including pain interference, anxiety, cocaine, and benzodiazepine use. The findings that M-ROCC is associated with reduced experiential avoidance, as well as increased interoceptive awareness and self-compassion, align with proposed mechanisms that are now extended to OUD treatment. Future larger randomized controlled trials are needed before effectiveness can be established and the role of these mechanisms can be confirmed.

Dispositional mindfulness and its relationship to exercise motivation and experience

Mindfulness is the psychological state of staying attuned to the present moment, without ruminating on past or future events, and allowing thoughts, feelings, or sensations to arise without judgment or attachment. Previous work has shown that heightened dispositional mindfulness is associated with the awareness of the importance of exercise, exercise self-efficacy, exercise motivation, and self-reported exercise level. However, more methodologically rigorous studies are needed to understand the relationship between mindfulness and the psychological mechanisms related to exercise motivation, including the identification of why individuals are motivated to engage in exercise, the subjective experience of exercise, and the propensity for exercise dependence and addiction. In this cross-sectional investigation, we utilized the framework of the Self-Determination Theory to examine the hypothesis that heightened dispositional mindfulness (as measured by the Mindful Attention Awareness Scale) would be associated with increased levels of exercise motivation that were derived by higher levels of autonomous self-regulation. Individuals were recruited from urban areas who self-reported either low (exercising 2 or fewer times per week for 20 min or less; n = 78) or moderate (exercising 1 or 2 times per week for 20 min or more; n = 127) levels of exercise engagement. As hypothesized, heightened dispositional mindfulness was significantly associated with heightened levels of exercise self-determination as measured by the Behavioral Regulations in Exercise Questionnaire, with this effect being driven by negative associations with amotivation, external regulation, and introjected regulation. Additionally, we found that heightened dispositional mindfulness was associated with lower levels of psychological distress upon exercise and decreased exercise dependence/addiction. Overall, increased dispositional mindfulness may support a healthy relationship with exercise. These findings have implications for the utility of mindfulness interventions to support the regulation of exercise behaviors in service of enhancing exercise motivation and engagement.

Effects of exercise and psychological interventions on smartphone addiction among university students: A systematic review

Background and aims

Among the large number of studies on smartphone addiction, only a few randomized controlled trials on exercise and psychological interventions for smartphone addiction by university students have been published. This study aims to systematically investigate the impact of exercise and psychological interventions on smartphone addiction among university students.

Methods

The PRISMA guidelines were adopted for this systematic literature review. Prominent academic databases such as Web of Science, PubMed, ProQuest, Cochrane Library, China National Knowledge Infrastructure (CNKI) and PsycINFO were searched to find eligible studies published before Aug 2021. The overall quality of the articles was checked using the "QualSyst" tool by Kmet et al.

Results

From among 600 papers, 23 met the inclusion criteria and were incorporated into our systematic review. All of the studies were randomized controlled trials. The following thematic areas emerged as a result of the content analysis: study selection and design, as well as study characteristics (participants, intervention, comparisons, and outcomes).

Discussion and conclusion

The literature on exercise and psychological interventions for smartphone addiction is scarce. There is a need to introduce new interventions and to validate the effectiveness of combined interventions. Our findings suggest that exercise and psychological interventions may help to reduce smartphone addiction. This combination was more effective compare to exercise or psychological intervention on mental health and addiction among university students. Future research should combine exercise and psychological interventions, focusing on university students, especially females, who are vulnerable to smartphone addiction. Further studies should focus on the cross-section of neuropsychology, cognitive psychology, and sports science to provide combined interventions in physiological and psychological direction.

Pre-Molecular Assessment of Self-Processes in Neurotypical Subjects Using a Single Cognitive Behavioral Intervention Evoking Autobiographical Memory

In the last 20 years, several contributions have been published on what concerns the conceptual and empirical connections between self-processes. However, only a limited number of publications addressed the viability of those processes to characterize mental health in neurotypical subjects with a normative pattern of neurodevelopment. Furthermore, even fewer experiments focused explicitly on the complexity of studying neurotypical phenomenal data. On the one hand, this normative pattern is commonly associated with mental health and a multifaceted self-concept and well-being. On the other hand, well-being is often related to a healthy cognitive life. However, how such intricate and complex relation between self-processes is established in neurotypical subjects requires further evidence. The novelty of this work is thus studying the first-person experience, which is correlated with the mental events aroused by a cognitive behavioral intervention. The prior methodology that led to the complete characterization of a neurotypical sample was already published by the authors, although the materials, the methods, the sample screening, and the sample size study required further explanation and exploration. This paper's innovation is hence the phenomenological assessment of subjects' self-regulation, which is used for mental health profiling, providing the basis for subsequent molecular typing. For that matter, a convenience sample of 128 (19-25-year-old) neurotypical young adults, healthy university students at the University of Lisbon, non-medicated and with no serious, uncontrolled, or chronic diseases, are characterized according to their cognitive functioning and self-concept. The procedure comprised (i) a mental status examination (psychological assessment) and (ii) a psychological intervention, i.e., a single cognitive behavioral intervention (intervention protocol). The psychological assessment was a standardized and structured clinical interview, which comprised the use of 4 psychological scales complementary to the classical Mental Status Examination (MSE). The intervention protocol applied a combined exercise of psychophysical training and autobiographical-self memory-recalling. The results permitted identifying and isolating four different subgroups (self awareness, self consciousness, reflective self, and pre-reflective self) in neurotypical subjects with discrete self-processes. The outcome of this study is screening four different aspects of self-reflection and the isolation between various forms of self-directed attention and their interconnections in these four mental health strata. The practical implication of this study is to fulfill an a priori pre-molecular assessment of self-regulation with separate cognitive characteristics. The reliability of these mental strata, their distinct neurophysiology, and discrete molecular fingerprint will be tested in a future publication by in silico characterization, total protein profiling, and simultaneous immunodetection of the neuropeptide and neuroimmune response of the same participants.

Mindfulness for internet use disorder: a study protocol of a systematic review and meta-analysis

INTRODUCTION

Internet use disorder (IUD) is on the rise and is associated with detrimental health consequences. Growing evidence suggests that mindfulness-either as a trait or cultivated in mindfulness-based programmes (MBPs)-is promising in preventing and treating IUD. With this systematic review and meta-analysis, we will examine (1) the association between trait mindfulness (TM) and IUD and (2) the effectiveness of MBPs in reducing IUD.

METHODS AND ANALYSIS

In October 2022, we will screen Medline, PsycINFO, PSYINDEX, CINAHL, Web of Science, and the Cochrane Register of Controlled Trials without language or publication date restrictions. We will conduct backward and forward citation searches of included studies and relevant reviews. We will include studies that evaluate either (1) the association between TM and IUD or (2) the effectiveness of MBPs in reducing IUD. Two reviewers will independently screen records, select and extract data, and rate the risk of bias. In total, we will conduct three meta-analyses: a first meta-analysis will be on the correlation between TM and IUD, a second meta-analysis will be on between-group data examining the effectiveness of MBPs in reducing IUD in randomised controlled trials (RCTs), and a third meta-analysis will be on within-group pre-postdata examining the effectiveness of MBPs in reducing IUD in all kinds of intervention studies. For the second and third meta-analyses, the primary outcome will be changes in IUD. We will explore moderators and sources of between-study heterogeneity and pursue a narrative synthesis of results. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the overall quality of evidence across intervention studies.

ETHICS AND DISSEMINATION

Ethics approval is not required. Results will be published in a peer-reviewed journal and presented at (inter)national conferences.

A Randomized Controlled Trial Evaluating the Effect of Tai Chi on the Drug Craving in Women

This study was conducted in the purpose of investigating the effect of Tai Chi on drug craving for women with drug disorders. One hundred and twelve women were recruited from a drug rehabilitation center in China, and 47 and 48 were finally analyzed in the control group and exercise group, respectively. The exercise group underwent a 3-month Tai Chi training, whereas the control group experienced no exercise intervention during the same time period. The drug craving was measured by the visual analog scale. In data analysis, repeated-measures were utilized to test the differences between the control and exercise group over the course of the experiment time. The mean of the craving score significantly dropped from pre-test (control: mean = 5.38, SD = 3.04; exercise: mean = 4.68, SD = 2.93) to post-test (control: mean = 4.03, SD = 2.73; exercise: mean = 1.91, SD = 1.90) in both groups (control group: t = 3.84, df = 46, p < 0.001; exercise group: t = 5.941, df = 47, p < 0.001), with more decrease witnessed in the exercise group. Repeated-measures analysis with a Huynh-Feldt correction showed the significant effect of time (F = 27.383, p < 0.001) as well as the study group by time interaction (F = 3.52, p = 0.024). Tai Chi can ameliorate the drug craving in women and it could be a supportive treatment for drug addiction.

Associations between specific sleep and circadian characteristics and alcohol use disorder criteria and problems

Given the significant heterogeneity of alcohol use disorder (AUD) and the increasing priority to understand individual profiles of AUD, pursuing symptom-level examinations of AUD is important. Disturbances in sleep and circadian rhythms have demonstrated robust associations with alcohol consumption and AUD, yet little research has examined these associations at the symptom- or problem-levels and research to date has focused on one or two sleep/circadian characteristics. We sought to investigate the associations between (a) specific AUD symptoms and (b) domains of alcohol-related problems, and multiple sleep characteristics, collected at a daily level in the naturalistic environment. Young adult drinkers were recruited from the community (N = 159, Mage = 23.9, 58.5% female, 6.3% Asian, 35.9% Black or African American, 51.6% White, 5.0% multiracial) and completed a baseline visit as well as up to 18 days of naturalistic assessment. Several sleep/circadian characteristics, including eveningness, later midsleep timing, and shorter total sleep time, were consistently associated with the hazardous use symptom, above and beyond alcohol consumption. Eveningness (beta[SE] = 0.21[0.00], p <.01) was a significant predictor of the alcohol-related problem domain of role interference. Exploratory analyses did not find significant associations between sleep/circadian characteristics and cannabis-related problems. The relationship between sleep/circadian characteristics and AUD and related problems may be driven by a narrower set of symptoms, such as hazardous use and role interference. This may be due to shared mechanistic dysfunction in domains such as reward processing or cognitive control. Thus, these alcohol-related symptoms and problems may be addressed through transdiagnostic treatment approaches that target these underlying mechanisms.

Exploring Contributing Factors of Solitary Drinking among Hong Kong Chinese Adolescents and Young Adults: A Descriptive Phenomenology

Adolescents and young adults mostly drink alcohol because of social activities. However, some drink outside of normative social contexts, exhibiting a behaviour pattern known as solitary drinking. Increasing evidence indicates that solitary drinking is strongly associated with problematic drinking in adolescents and young adults. However, it remains unclear why individuals initiate and maintain this drinking habit. To address this gap in the existing literature, the current study explored the factors contributing to solitary drinking in this population. Descriptive phenomenology was used. A convenience sample of 44 solitary drinkers aged between 10 and 24 were invited to undergo individual semi-structured interviews. All interviews were audio-recorded and transcribed verbatim. The data were analysed by two researchers separately using Colaizzi’s method. Using qualitative descriptions, the following factors were identified as explaining the initiation and continuation of solitary drinking among adolescents and young adults: (1) enhancement and coping drinking motives, (2) social discomfort, (3) reduced self-control, (4) automatic mental process, and (5) a desperate response to stressors. Since reduced self-control plays an important role in long-term addiction, future studies should be conducted to determine potential applications of mindfulness-based interventions to improve self-control, which may prevent the progression from solitary drinking to alcohol use disorder.

Brief Online Negative Affect Focused Functional Imagery Training Improves 2-Week Drinking Outcomes in Hazardous Student Drinkers: a Pilot Randomised Controlled Trial

BACKGROUND

Negative affect plays an important role in motivating problematic alcohol use. Consequently, training imagery-based adaptive responses to negative affect could reduce problematic alcohol use. The current study tested whether personalised online functional imagery training (FIT) to utilise positive mental imagery in response to negative affect would improve drinking outcomes in hazardous negative affect drinking students.

METHOD

Participants were 52 hazardous student drinkers who drink to cope with negative affect. Participants in the active group (n = 24) were trained online over 2 weeks to respond to personalised negative drinking triggers by retrieving a personalised adaptive strategy they might use to mitigate negative affect, whereas participants in the control group (n = 28) received standard risk information about binge drinking at university. Measures of daily drinking quantity, drinking motives, self-efficacy and use of protective behavioural strategies were obtained at baseline and 2 weeks follow-up.

RESULTS

There were three significant interactions between group and time in a per-protocol analysis: the active intervention group showed increased self-efficacy of control over negative affect drinking and control over alcohol consumption and decreased social drinking motives from baseline to 2-week follow-up, relative to the control intervention group. There were no effects on drinking frequency.

CONCLUSION

These findings provide initial evidence that online training to respond to negative affect drinking triggers by retrieving mental imagery of adaptive strategies can improve drinking-related outcomes in hazardous, student, negative affect drinkers. The findings support the utility of FIT interventions for substance use.

Addiction and COVID: Issues, Challenges, and New Telehealth Approaches

In recent decades, the United States has seen a substantial increase in the number of people diagnosed with substance use disorder (SUD). Both SUDs and COVID-19 separately have had, and continue to have, a widespread impact on our society. While they are two distinct entities, they are intricately related and have been shown to influence one another. Lockdown mandates intended to enhance public safety produced unintended consequences for people with SUDs by decreasing access to treatment and disrupting their current care. Telehealth could offer a solution to this disruption as its utilization expands the provider’s reach and increases access to treatment in underserved populations, including those with SUDs. The use of telemedicine seems to result in higher rates of patient satisfaction, compliance, and treatment retention rates while maintaining the need for social distancing. Even when pandemic restrictions resolve, telehealth can continue to provide invaluable benefits to individuals with addiction, particularly those in rural America. In summary, ongoing research regarding telehealth delivery and the expansion of telehealth is a byproduct of the pandemic and can advance the American healthcare system beyond the days of COVID-19. This manuscript will review studies regarding the use of telehealth in SUD with the hope that further research within and beyond the COVID-19 pandemic will lead to the increased use of telehealth by those involved in and those receiving care for SUDs.

Comparing a mindfulness- and CBT-based guided self-help Internet- and mobile-based intervention against a waiting list control condition as treatment for adults with frequent cannabis use: a randomized controlled trial of CANreduce 3.0

BACKGROUND

Though Internet- and mobile-based interventions (IMIs) and mindfulness-based interventions (generally delivered in-situ) appear effective for people with substance use disorders, IMIs incorporating mindfulness are largely missing, including those targeting frequent cannabis use.

METHODS

This paper details the protocol for a three-arm randomized controlled trial comparing a mindfulness-based self-help IMI (arm 1) and cognitive-behavioral therapy (CBT)-based self-help IMI (arm 2) versus being on a waiting list (arm 3) in their effectiveness reducing cannabis use in frequent cannabis users. Predictors of retention, adherence and treatment outcomes will be identified and similarities between the two active intervention arms explored. Both active interventions last six weeks and consist of eight modules designed to reduce cannabis use and common mental health symptoms. With a targeted sample size of n = 210 per treatment arm, data will be collected at baseline immediately before program use is initiated; at six weeks, immediately after program completion; and at three and six months post baseline assessment to assess the retention of any gains achieved during treatment. The primary outcome will be number of days of cannabis use over the preceding 30 days. Secondary outcomes will include further measures of cannabis use and use of other substances, changes in mental health symptoms and mindfulness, client satisfaction, intervention retention and adherence, and adverse effects. Data analysis will follow ITT principles and primarily employ (generalized) linear mixed models.

DISCUSSION

This RCT will provide important insights into the effectiveness of an IMI integrating mindfulness to reduce cannabis use in frequent cannabis users.
